Buterfly Species Diversity and Abundance in Taraba State College of Agricultural Science and Technology, Jalingo Taraba State, Nigeria

Butterflies are in the order Lepidoptera, which are insect with scaled wings. Over 28,000 species of butterflies exist in the world today contributing to one-quarter of all named species on the earth. Lepidoptera is important to man and the health of the environment. Butterflies play a significant role in the pollination of crops and as aesthetics. The study assessed the diversity and abundance of butterfly species in the Taraba State College of Agricultural Science and Technology, Jalingo, Nigeria. Line transects were used to survey two study sites within the School using handheld sweep nets in January to March, 2024. Data were analyzed using descriptive statistics. A total of 1,153 individuals representing 21 butterfly species belonging to 3 families were recorded across the two study sites. Out of these, members belonging to the family Lyceanidae were the most csommon with 6 species being recorded accounting for 46.2% of the total species and 93.2% of total number of individuals collected in engineering complex while members belonging to the family Nymphalidae were the most common with 10 species being recorded accounting for 52.6% of the total species and low in the total number of individuals with 37.8% collected in staff quarters. Species richness, evenness and diversity varied from study sites to sites (R= 2.7014 – 2.0293), (e= 0.6691 – 0.6317), (H1= 1.9700 – 1.6203). It was recommended that management effort towards conservation be put in place so as to ensure sustenance of butterflies and ecosystem services derived from them, and further exploration of butterfly species be done to update this checklist.

Diversity of Ichthyofauna and their Abundance in Ghaghara River, Siwan District, Bihar, India

The Ghaghara River, a significant tributary of the holy River Ganga, travels across northern India., providing essential water resources for agriculture, communities and biodiversity. The river's fish diversity is vital for maintaining local ecological balance and supporting livelihoods. Fish biodiversity and different diversity indices were evaluated in the study area from August 2021 to July 2022. Data was collected from four locations namely Darauli (S-1), Rakauli (S-2), Phulwariya (S-3) and Semariya (S-4) of the Ghaghara River and we found 61 species belongs to 47 genera, 21 families and 07 orders. Cypriniformes were the most common order, accounting for 42% of fish species, followed by Siluriformes (31%), and Perciformes (18%). The most prevalent family is Cyprinidae, which accounts for 39.3% of the fish fauna (24 species), followed by Bagridae (06 species) and Sisoridae (4 species). Total number of individuals, relative abundance (percentage catch), minimum and maximum size of each species were calculated. However, the river’s aquatic ecosystems, particularly its fish populations are increasingly under threat due to human activities, including habitat degradation, pollution, overfishing and the construction of hydropower projects. This study aims to assess the fish diversity of the Ghaghara River and explore the current conservation challenges and opportunities.

Pawpaws prevent predictability: A locally dominant tree alters understory beta‐diversity and community assembly

AbstractWhile dominant species are known to be important in ecosystem functioning and community assembly, biodiversity responses to the presence of dominant species can be highly variable. Dominant species can increase the importance of deterministic community assembly by competitively excluding species in a consistent way across local communities, resulting in low site‐to‐site variation in community composition (beta‐diversity) and nonrandom community structure. In contrast, dominant species could increase the importance of stochastic community assembly by reducing the total number of individuals in local communities (community size), resulting in high beta‐diversity and more random community structure. We tested these hypotheses in a large, temperate oak‐hickory forest plot containing a locally dominant tree species, pawpaw (Asimina triloba; Annonaceae), an understory tree species that occurs in dense, clonal patches in forests throughout the east‐central United States. We determined how the presence of pawpaw influences local species diversity, community size, and beta‐diversity by measuring the abundance of all vascular plant species in 1 × 1‐m plots both inside and outside pawpaw patches. To test whether the presence of pawpaw influences local assembly processes, we compared observed patterns of beta‐diversity inside and outside patches to a null model in which communities were assembled at random with respect to species identity. We found lower local species diversity, lower community size, and higher observed beta‐diversity inside pawpaw patches than outside pawpaw patches. Moreover, standardized effect sizes of beta‐diversity from the null model were lower inside pawpaw patches than outside pawpaw patches, indicating more random species composition inside pawpaw patches. Together these results suggest that pawpaw increases the importance of stochastic relative to deterministic community assembly at local scales, likely by decreasing overall numbers of individuals and increasing random local extinctions inside patches. Our findings provide insights into the ecological processes by which locally dominant tree species shape the assembly and diversity of understory plant communities at different spatial scales.

Length–weight relations and condition factors of several endemic and native fish species from Anatolian freshwater

This study analyzed the length–weight relations and condition factors of 13 species belonging to three highly endemic genera: Oxynoemacheilus (6), Seminemacheilus (2) and Cobitis (5). Fish were sampled in several streams and lakes using a backpack electroshocker. Analyses were based on a total number of individuals, which was n = 304. A linear regression model was applied to determine the relationship between fish length and weight. The coefficient of determination (R2) ranged from 0.950 to 0.980 for all populations (p < 0.05). Allometric coefficient ‘b’ values ranged from 2.498 to 3.201 for Oxynoemacheilus, from 2.970 to 2.127 for Seminemacheilus, and from 2.111 to 3.076 for Cobitis populations. Fulton’s condition factor for Oxynoemacheilus, Seminemacheilus and Cobitis ranged from 0.391 to 3.080. This study addresses gaps in LWR and CF information for a number of ecologically important freshwater fish species. It is expected that the results of this research provide baseline data for further fisheries management studies and may support conservation studies of related species.

The impact of contact-network structure on important epidemiological quantities of infectious disease transmission and the identification of the extremes.

An individual-based stochastic model was developed to simulate the spread of an infectious disease in an SEIR-type system on all possible contact-networks of size between six and nine nodes. We assessed systematically the impact of the change in the population contact structure on four important epidemiological quantities: i) the epidemic duration, ii) the maximum number of infected individuals at a time point during the epidemic, iii) the time at which the maximum number of infected individuals is reached, and iv) the total number of individuals that have been infected during the epidemic. We considered the potential relationship of these quantities as the network changes and identified the networks that maximise and minimise each of these in the case of an epidemic outbreak. Chain-like networks minimise the peak and final epidemic size, but the disease spread is slow on such contact structures which leads to the maximisation of the epidemic duration. Star-like networks maximise the time to the peak whereas highly connected networks lead to faster disease transmission, and higher peak and final epidemic size. While the pairwise relationship of most of the quantities becomes almost linear, or inverse linear, as the network connectivity increases and approaches the complete network, the relationships are non-linear towards networks of low connectivity. In particular, the pairwise relationship between the final epidemic size and other quantities is changed in a 'bow-shaped' manner. There is a strong inverse linear relationship between epidemic duration and peak epidemic size with increasing network connectivity. The (inverse) linear relationships between quantities are more pronounced in cases of high disease transmissibility. All the values of the quantities change in a non-linear way with the increase of network connectivity and are characterised by high variability between networks of the same degree. The variability decreases as network connectivity increases.

Tracing Leprosy: The paleopathological study of the individuals excavated from the Sant Llàtzer leprosarium in Barcelona, Spain (12th-18th c.)

ObjectiveOur objectives are twofold: to analyse the frequency of leprosy-related pathological lesions in the cemetery of Sant Llàtzer Hospital (12th-18th c.); and to examine how individuals affected by the disease were perceived and integrated into society during that period in Barcelona. MaterialsThe skeletal remains of 87 individuals recovered from the cemetery. MethodsAll remains were analysed macroscopically and, when required, radiographed. ResultsOf the total number of individuals (n=87), 21 (24.1 %) showed evidence indicative of leprosy. Notably, the frequency of leprosy cases was lower in the 13th-15th c. (10 %; n = 50), the only period for which multi-person graves were documented. ConclusionsThe frequency of leprosy-related lesions in Sant Llàtzer is similar to that observed in other European Christian leprosaria, although it varies across the centuries. There is no funerary evidence that leprosy sufferers were treated differently than other citizens. SignificanceThe cemetery of Sant Llàtzer, the first in Spain directly linked to a leprosarium, uniquely spans a significant period of activity. Its exceptionally preserved remains and rich records have offered unparalleled insight into the disease and its profound social implications. LimitationsLeprosy affects the bone in only a small percentage of untreated cases. Moreover, poor preservation of skeletal remains may prevent diagnosis. Suggestions for Further ResearchBiochemistry, genomics, and proteomics might provide new insights into the disease, the origin and migrations of the individuals buried in Sant Llàtzer, as well as other aspects of their daily lives.

Thousands of Years of Pastoralism Don't Count: Coprophagous Beetles Prefer Exotic Alpaca Dung to That of Cattle.

Dung beetles mostly feed on mammal dung. Throughout the European Alps, the dung produced by local domestic ungulates attracts many species of dung beetles, giving rise to rich and diversified communities that play an important role in the Alpine agricultural ecosystem. There is, therefore, understandable concern about the introduction of exotic livestock, such as alpacas (Vicugna pacos (Linnaeus, 1758)), into the region. This research studied dung beetle assemblages in an Alpine valley where both cattle and alpacas are raised. We used standardized pitfall traps baited with alpaca or cow dung along altitudinal transects to assess the "attractiveness" of the two resources to dung beetles. Most species entered both trap types. The average number of species per trap did not vary significantly and the nMDS trap ordination largely overlapped, but the total number of individuals and the average number of individuals per trap were higher in traps baited with alpaca dung. This difference was largely due to the preference of the dominant species Euheptaulacus carinatus (Germar, 1824) for alpaca dung-baited traps. Moreover, both the abundance and specific richness changed with altitude, being greatest in alpaca traps during July at intermediate altitudes. IndVal analyses showed that eight out of nine species (all Aphodiinae) showed a preference for alpaca traps. Since the microclimatic conditions (i.e., temperature) of the two trap types were virtually the same, it is reasonable to consider trophic preferences as the source of the observed differences. Finally, we also sampled the beetles present in the alpaca latrines and cow dung pats deposited on pastures, providing confirmation that dung beetles do indeed visit the dung of both species. Our results emphasize the usefulness of polyphagia and the trophic flexibility of dung beetles, providing evidence that the long history of pastoralism in the Alps has not led local species to adapt to the dung of domestic ungulates. The results also suggest that alpaca breeding could be a sustainable activity since, thanks to the work of dung beetles which feed upon and move the dung into their tunnels (as occurs with cattle dung), there is less need for farmers to remove the dung from pastures.

Floristic diversity and species composition along altitudinal gradient in the alpine ecosystem of the cold desert region in Western Himalaya, India.

In India, the Trans-Himalayan zone lies in the rain shadow of the main Himalayan region and is usually described as a "high-altitude cold desert". These regions are represented by sparse but unique vegetation composition. The present study is an attempt to investigate the vegetation composition in the alpine ecosystem of the cold desert landscape of the Nelang Valley in Western Himalayas (Uttarakhand), India. The result of the study reveals the existence of a total of 68 taxa of higher plants (56 genera and 28 families). These include herbs (51 species), shrubs (13 species), climbers (one species), and trees (three species). Herbaceous species (52 species) contributed the maximum species richness; Artemisia, Astragalus, and Juniperus were the dominant genera, followed by Aster, Lonicera, Oxytropis, Poa, and Salix. The valley showed irregular distribution of plant species richness along the altitudinal gradient, and maximum taxa exhibited between 3,500 m and 3,600 m of altitude band. In the Nelang Valley, the total number of phytodiversity individuals exhibited a significant linear decline with increasing altitude (3,100-4,300 m). Further, the study recorded 33 important medicinal plants used in the traditional system of herbal medicine in the Himalayan region. Juniperus semiglobosa shows dominance with a maximum important value index (IVI) (31.77), followed by Pinus wallichiana (29.19) and Cedrus deodara (10.72) in the treeline ecotone of the valley. Rapid Threat Assessment shows that Artemisia dubia and Artemisia roxburghiana were the most vulnerable herb species in the region. The information thus generated will be useful for suggesting ecological management and conservation planning.

Fruit flies (Diptera: Teprithidae) and their parasitoid (Hymenoptera: Braconidae) species from registered snake fruit production during early rainy and dry seasons in the Special Region of Yogyakarta, Indonesia

Exportation of snake fruit from Indonesia to China, Australia, and New Zealand has been hindered due to fruit fly infestations (Diptera: Teprithidae). The goal of this study was to identify fruit flies and their parasitoid species from registered snake fruit productions in Turi, Sleman, that have reached packaging houses during early rainy and dry seasons. Fruit fly species were morphologically identified from collected rejected or damaged snake fruit. Parasitization was calculated by dividing the number of emerging parasitoid species by the total number of parasitoid and fruit fly individuals. The population of fruit flies and parasitoids was then compared to climatic data. Female fruit flies that emerged from snake fruit possessed spots on their front preapical femur, concluding that these species were Bactrocera carambolae. The average fruit fly that emerged per fruit was 16.5 individuals. Only one parasitoid species emerged and possessed notauli on mesonotum that elongated to the center and petiole and longitudinal metasomal tergum 2, implying that this parasitoid species was Fopius arisanus with an average population of 5.71 individuals with a parasitization percentage of 26.86%. Results from this research concluded that the fruit fly species collected from registered snake fruit productions in Turi, Sleman, during the early rainy season and dry season was Bactrocera carambolae with a low parasitization level by Fopius arisanus. This parasitization level may be affected by fruit fly density and climatic factors, such as humidity and rainfall.

Parental Birth Order and the First Stage of Tracking Into Schools: Evidence From General Upper Secondary Educational Attainment in Finland

ABSTRACTNo previous study on the interrelation between parental birth order and offspring educational attainment has analysed the first stage of tracking into schools, which in many countries is highly selective of persons who aim for university studies. We do so and examine how parental birth order is associated with attainment of general upper secondary education in Finland. Three‐generational register data on the total population are used to assess how the probability of having the matriculation examination at age 20 is associated with parental birth order. The total number of individuals in the child generation is 377,038. We find that the probability of having the matriculation examination decreases with parental birth order. Within‐family analyses using cousin fixed effects models, which account for unobserved characteristics in the extended family, show that having later‐born parents, and in particular a later‐born father, is negatively associated with first tracking into schools. These patterns can solely be attributed to the fact that earlier‐born parents are highly educated and found in higher social classes than later‐born parents. The results largely corroborate findings from similar analyses of length of schooling in Sweden, although the contribution of parental education and social class is notably stronger in our study context.

Estimating the Reduction of Socioeconomic Inequalities for a More Physically Active Society: A Cross-Sectional Study of the European Union Country Members.

Socioeconomic inequalities significantly impact the accessibility of resources necessary for physical activity, thereby influencing overall physical activity levels and contributing to broader health disparities. Nevertheless, evidence is lacking on quantifying the increase of people who would be physically active through reducing inequalities by a higher socioeconomic position. We conducted secondary data analysis on the 2017 cross-sectional survey of the European Union's population aged ≥18years (n = 27,538). By estimating socioeconomic status percentages and odds ratios between socioeconomic status (education, occupational social class, and economic issues) and physical activity, we calculated age-standardized Prevented Fraction for Population and the total number of individuals that would meet physical activity guidelines by a higher socioeconomic status (eg,from low to middle or high socioeconomic status), along with scenarios of reduced socioeconomic disparities, controlling for age, gender, place of residence, and marital status. A higher socioeconomic status could promote physical activity for a total of 93.0 (84.5-101.8) million people through university education, 28.5 million via high-ranked occupations (24.6-32.8), and 137.9 (129.5-146.2) million by less economic issues (compared with primary education, low-manual occupations, and having economic issues most of the time, respectively)-equivalent to 35.46%, 14.49%, and 55.42% of the Prevented Fraction for Population. Reducing socioeconomic inequalities by 50% could raise these estimations to 148.1 million (134.0-162.8) through education, 43.5 million (37.5-50.3) through occupation, and 223.6 million (209.3-237.8) through less economic issues. Enhancing access to university education, high-ranked occupations, and income impacts physical activity population levels in the European Union.

Nutritional management, skipping breakfast, glycemic control, and cardiovascular risk on type 2 diabetes mellitus

Abstract Background Meal timing is an emerging field that investigates the influence of eating patterns on circadian rhythm and general health. There is still disagreement in the literature as to whether eating windows could impact weight gain and biochemical markers. Purpose 1- Evaluate the impact of nutritional interventions on weight, body mass index (BMI), waist circumference (WC), fasting blood glucose (FG), glycated hemoglobin (HbA1c), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglycerides, systolic blood pressure (SBP), and diastolic blood pressure (DBP), between 0th and 12th month in Type 2 Diabetes Mellitus (T2D); 2-Observe breakfast skipping and sleep disorders, and also analyze the influence of these data with possible changes in anthropometric and biochemical markers. Methods This experimental and observational study recruited 44 participants with T2D. The assessments were carried out in October 2022 and 2023. The nutritional assessment consisted of prescribing a personalized eating plan (Mediterranean diet and DASH). Statistical analysis: For the variables "breakfast habits", "nocturnal awakenings", and "sleep duration", the numbers of participants were converted into percentages of the total number of individuals. Parametric variables were compared using the paired t-test and non-parametric variables were compared by the Wilcoxon test. To evaluate the influence of the habit of eating breakfast and sleep disorders on quantitative variables, variations were calculated between the 0th and 12th month between participants who had or did not have the habit of eating breakfast and had or did not have sleep disorders. Parametric variables were compared using the unpaired t test and non-parametric variables using the Mann-Whitney test. Parametric data were presented as mean ± standard deviation and non-parametric data as median ± interquartile range, both accompanied by the dispersion of all repetitions. α<0.05 and P<0.05 were adopted. Results Significant reductions were found between the 0th and 12th month of FG, HbA1c, LDL-C, triglycerides, SBP, DBP, BMI, WC, and weight (p<0.0001). Regarding breakfast habits, in the 1st month, 77.3% of participants skipped this meal, reducing to 13.6% in the 12th month. For sleep duration, in the 1st month, 90.9% of participants slept less than 6 hours, reducing to 40.9% in the 12th month. For nocturnal awakenings, 70.5% of participants had at least 1 awakening in the 1st month, reducing to 54.5% in the 12th month. For influence analysis, no significant differences were found between changes in FG, HbA1c, LDL-C, triglycerides, SBP, DBP, BMI, WC, and weight on breakfast habit or sleep disorders, except for HDL-C and sleep disorders (p<0.005). Conclusion Nutritional management improved biochemical markers, reduced anthropometric data, regulated the eating window, reduced nocturnal awakenings, and optimized sleep duration in patients with T2D.

Evaluation of variability of morphometric traits of plants and age spectrum of cenopopulations of Matthiola daghestanica (Brassicaceae) of the Piedmont and Mid‐mountain Dagestan, Russia

Aim: Study of intra‐ and interpopulation variability of quantitative traits of Matthiola daghestanica (Conti) N. Busch and assessment of the age spectrum of natural cenopopulations of Piedmont and Mid‐mountain Dagestan. The material consisted of 90 plants (shoots with inflorescences) taken from coenopopulations of various locations of the studied species (450, 610 and 960 m above sea level). An analysis of the variability of 12 morphological traits of M. daghestanica was carried out. To assess the age spectrum, 5x5 m test plots were laid out at three points (75 m²), where the age (ontogenetic) states of M. daghestanica guided by methods from the works of T.A. Rabotnov (1950) and A.A. Uranov (1957).The variability of the morphological traits of the Dagestan endemic M. daghestanica has been studied and its age spectrum in the natural cenopopulations of Piedmont and Mid‐mountain Dagestan has been assessed. The most variable were the weight traits. Analysis of the significance of the differences between the selected groups using the t‐test confirmed that “Chakh‐Chakh” is highly isolated from other coenopopulations, and to the greatest extent from “Chirkata”. The linear trait “length vegetative features” introduces the greatest significant differences between all coenopopulations. The percentage of age states from the total number of individuals varies among populations. The age spectrum of M. daghestanica in the “Chirkata” cenopopulation is represented by a predominance of the juvenile (25 %) and virginal (25 %) groups and in the “Ashilta” cenopopulation by the adult group (23.9 %). Among the age states of the generative period in all cenopopulations, young generative individuals prevail (16.7–19.4 %). The largest number of middle‐aged generative individuals is in the “Chakh‐Chakh” cenopopulation (16.3 %).Analysis of the variability of morphological characteristics of M. daghestanica plants showed that linear and numerical traits for the three cenopopulations are less variable. Significant variability was revealed in weight characteristics: “mass caulis and leaves” (518.3–818.7 mg); “total mass shoot” (990.7–1342.8 mg). The squared Mahalanobis distances of the characters studied revealed the isolation of the “Chakh‐Chakh” cenopopulation from the other two (“Achilta”, “Chirkata”). The age spectrum of M. daghestanica coenopopulations is similar in the Piedmont and Mid‐mountain Dagestan, despite the different number of age states. Cenopopulations of M. daghestanica are normal, capable of self‐renewal, characterized by recovery indices of 1.2–2.8 %.

Application of bevacizumab in the management of meningiomas: a systematic review and meta-analysis.

Meningiomas are the most common intracranial lesions and constitute one-third of diagnoses. Surgical resection is the gold-standard treatment option. In case of treatment failure, therapeutic options are limited. Bevacizumab is a vascular endothelial growth factor ligand-binding monoclonal antibody that prevents angiogenesis. This study aims to investigate the efficacy and feasibility of bevacizumab in meningiomas On December 30, 2023, a systematic search was conducted according to PRISMA guidelines using the PubMed, Scopus, Web of Science, and Embase databases. This study is conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flowchart. Our study included 12 studies, comprising 243 individuals and 310 tumors. Most of the studies were retrospective (80%). Most of the patients were male (47.9%). The bevacizumab was mostly administered intravenously at 10mg/kg every two weeks (77.8%). The mean progression-free survival (PFS) and overall survival (OS) were 19.1 ± 4.7 and 23.9 ± 8.4 months, respectively. The response rate was 0.33 (95%CI: 0.14-0.60). The PFS-6, PFS-12, and PFS-24 were 0.80 (95% CI: 0.64-0.89), 0.66 (95%CI: 0.46-0.82), and 25% (95%CI: 0.16-0.37), respectively. The OS-6, OS-12, and OS-24 were 0.89 (95% CI: 0.80-0.96), 0.86 (95%CI: 0.65-0.95), and 0.48 (95%CI: 0.16-0.82), respectively. The meta-regression identified the total number of individuals, number of tumors, gender, WHO II/III, and prior resection as a possible source of heterogeneity for outcomes. This study highlights the effectiveness of bevacizumab in meningiomas, especially in refractory, high-grade, or neurofibromatosis patients.

Biochemical profile of the native seaweed fly Fucellia maritima (Haliday, 1838) (Diptera: Anthomyiidae) reared on five different substrates

Abstract The sustainability of aquaculture production is crucial for the industry’s long-term viability. Diversification of feed ingredients is a key component in achieving this sustainability. Considered a promising alternative to traditional feed ingredients, terrestrial insect meals often lack sufficient n-3 polyunsaturated fatty acids (PUFA). This study explores the potential of marine insect species, specifically evaluating the influence of five different substrates on the growth and composition of the European native seaweed fly, Fucellia maritima. The substrates tested include a brown seaweed (Fucus sp.), a green seaweed (Ulva sp.), a red seaweed (the invasive Agarophyton vermiculophyllum), the invasive freshwater hyacinth (Eichhornia crassipes), and fish processing waste (codfish Gadus morhua frames). Results show no significant difference in the number of individuals per substrate, although Fucus sp. had a higher total number of individuals completing their life cycle. In contrast, feeding on codfish frames resulted in a lower number of completed life cycles, while E. crassipes led to no survival. Protein content in adult flies ranged from 55.2% to 56.7%, and in pupae, it ranged from 46.1% to 48.7% across different feeding substrates. Notably, pupae fed with Ulva sp., exhibited the highest protein content at 48.7%. Lipid content in adult flies ranged from 10.0% to 13.0%, while in pupae, it ranged from 8.8% to 11.4%. Codfish frames had the highest lipid content in both pupae (11.4%) and adults (13%). The most abundant fatty acid in Fucus sp. – fed pupae and adult flies was oleic acid (18:1 n-9), while palmitoleic acid (16:1 n-7) dominated in other treatments. It is worth highlighting that docosahexaenoic acid (22:6 n-3) was reported for the first time in a seaweed fly, namely when supplied with fish processing waste. These findings suggest that Fucellia maritima may be a promising complementary ingredient for formulating marine aquafeeds.

P45: Multimorbidity Patterns and their association with depressive symptoms among elderly: A Latent Class Analysis of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) data

Objectives: To explore how clusters of chronic health problems can impact depression in older adults.Methods: We performed a latent class analysis using the baseline data from The Brazilian Longitudinal Study of Aging (ELSI-Brazil). Depression was assessed using the Center for Epidemiological Studies Depression Scale (CES- D8). Scores of 4 or higher on the CES-D8 were considered positive for depression. Fourteen self-reported conditions (Diabetes, Systemic Arterial Hypertension, Angina, Myocardial Infarction, Chronic Kidney Disease, Heart Failure, Stroke, Low Back Pain, Arthritis, Osteoporosis, Asthma, Chronic Obstructive Pulmonary Disease, High Cholesterol, and Cancer) were evaluated and combined as a total number of chronic conditions.Results: The total number of individuals in the sample was 4672. The best resulting model is composed of 4 latent classes. The latent classes were organized as follows: Cardiovascular Multimorbidity (Class1); No multimorbidity (Class 2); Musculoskeletal Multimorbidity (Class 3); and Inflammatory Multimorbidity (Class 4). We identified that, in comparison with class 2, (considered the reference class due to the absence of multimorbidity), the odds ratio for depression was 2.56 for the Cardiovascular Multimorbidity class, 2.86 for the Musculoskeletal Multimorbidity class, and 4.59 for the Inflammatory Multimorbidity class.Conclusions: We found that various patterns of multimorbidity are associated with depression when compared with a single disease and that Inflammatory Multimorbidity has the greatest impact on depression.

Bioarchaeological analysis of human skeletal remains associated with the wrecking of the retourschip “Batavia”, 1629: burials BIB 11–14

The voyage and subsequent mutiny associated with the wrecking of the VOC retourschip “Batavia” (1629) in the Houtman Abrolhos, off the western coast of Australia, represents one of the earliest documented European encounters with Australia. Much of our understanding of events surrounding the mutiny is detailed in a rich historical record, supplemented in the modern period with targeted archaeological research. Most recently, a large-scale multidisciplinary project, ‘Shipwrecks of the Roaring Forties’ (2014–2019), resulted in the archaeological excavation and analysis of a further 11 individuals on Beacon Island, long dubbed ‘Batavia’s Graveyard’, where the survivors of the wrecking spent several months trying to survive. The latter work brings the total number of individuals recovered from Beacon Island to 21. The present paper considers research undertaken on Beacon Island between 2015 and 2018, specific to the archaeological excavation and analysis of four individuals, designated BIB-11 to BIB-14. These burials represent the first discovery of human remains on the Island through archaeological investigations and for which their burial context and physical integrity had not been compromised by prior human actions, intentional or otherwise. The archaeological and biological anthropological interpretation of these individuals and their burial context, relative to the other sites excavated on the Island, facilitates new and significant insight into these people and the events surrounding their untimely demise on Beacon Island in the early seventeenth century.

Continuous data-gathering system on migrants: a critical review

The investigation examines the continuous system as one of the two most common forms of migrant data-gathering today. The system is defined as a set of tools that obtains migration data on changes in the registration of the place of previous residence within the country or immigration record, including the total number of individuals entering or leaving the country and the type of visa issued to them. The strengths of the continuous system are noted, which lie in its ability to generate data on a regular basis and be useful to the authorities at the national level during the management of migration challenges and forecasting of various processes. The factors that influence the rejection of this data-gathering form today are highlighted, such as: 1) difficulty of conducting a comparative analysis between countries; 2) blurring of the entry category, which makes its unification problematic; 3) issues with monitoring of persons with unsettled (legal) status; 4) lack of recording of undocumented individuals in the continuous record of migrants; 5) system bias in focusing on emigration, ignoring the dimension of immigration. The idea about the lower level of use of the continuous system in our time due to the need for large financial resources, technological support, real agreement and coordination of joint actions between the governments of national states is substantiated as an unlikely scenario, taking into account the political, economic, cultural and social, etc. differentiation in the world. Attention is paid to the issue of prospects for the implementation of a continuous data-gathering system in the future based on the analysis of recent research and changes in the status of migration in the context of sustainable development. It is emphasized that, given the current challenges, the form will be used in the future, continuously recording data on displaced persons, but not claiming primacy in the process of systematizing information on global flows of migrants.
