An Investigation on the Food and Feeding Habit of <i>Sarotherodon Galilaeus </i>(Cichlidae) in Egbe Reservoir, Ekiti State, Nigeria

A study on the food and feeding ecology of <i>Sarotherodon galilaeus</i>, a species of cichlid found in Nigeria's Egbe Reservoir. For the investigation, 305 fish specimens were used. The stomach contents were analyzed using diet indices such as stomach fullness, numerical approach, and frequency of occurrence method. Additionally, the Geometric Index of value (GII) was used to determine the relative value of these food products. The findings showed that both adult and juvenile <i>Sarotherodon galilaeus</i> fed on nine various food sources. The variety of food items included rotifers, algae, desmids, diatoms, protozoa, detritus, aquatic insects, aquatic plants, and insect larvae. The inclusion of detritus in the food items suggests that the fish species graze on both surface water and bottom sediments. Algae had the highest frequency of occurrence (46.39%) in both sizes and seasons, whereas rotifer had the lowest value (1.55%). Since it is possible to create the artificial diet required for this species' mass production in Nigeria, the findings of this study are very significant for the culture of that species<i>. Sarotherodon galilaeus</i> can be classified as an omnivore because it consumed a variety of foods. Since feeding accounts for 60–65% of the aquaculture industry for any species being raised, research on fish diet and feeding habits is essential to developing an effective aquaculture management system. As a result, the fish species may be raised in our garden.

Light Precipitation rather than Total Precipitation Determines Aerosol Wet Removal.

Precipitation scavenging is an important sink for both organic and inorganic pollutants in the atmosphere. However, there has been controversy over the relative importance of different precipitation characteristics (i.e., the precipitation amount, intensity, frequency, and duration) in the removal of air pollutants. It is critical to reach a consensus on which precipitation characteristics are most significant for aerosol wet removal. In this study, the analysis of multisource in situ observations of aerosol wet deposition worldwide indicates that the precipitation frequency plays a first-order role in scavenging aerosols. This is because large amounts of air pollutants are efficiently removed at precipitation initiation. As the duration and amount of precipitation increase, the scavenging efficiency decreases sharply. Consequently, it is featured that light precipitation, due to its high frequency of occurrence, rather than total precipitation, determines climatological aerosol wet deposition. To further confirm this, a state-of-the-art global climate model with convection resolved is modified to reduce the light precipitation frequency in both stratiform and convective cloud regimes. Results show widespread increases in aerosol optical depth (AOD) due to the reduced wet deposition. The spatial distribution of aerosol wet deposition changes resembles that of changes in the light precipitation frequency rather than that of total precipitation changes. These findings are consistent with those from the Coupled Model Intercomparison Project Phase 6 multimodel simulations, which show that the intermodel uncertainty in simulated AOD correlates more strongly with the uncertainty in light precipitation frequency than with that in total precipitation.

The Mycobiota of Library Books in Russia.

Abstract-Numerous studies of microorganisms isolated from the surface of cultural heritage objects, including library documents, are regularly carried out in different countries. Although the micromycete composition in each case varies, some species are constantly isolated. The structure of micromycete communities that inhabit library documents was studied in 57 cities of Russia located in seven federal districts (Northwestern, Central, Southern, Volga, Ural, Siberian, and Far Eastern). Micromycetes of 95 species from 32 genera were isolated and identified. The mycobiota of the library documents represented by Ascomycota has more than 90% of the species richness; Mucoromycota make up 3-9% and Basidiomycota, 3-4%. The Aspergillaceae family was the leading family: it accounted for 48.5-67.3% of the total species richness. In all regions, species diversity is moderate: the Shannon index ranged from 2.7 to 3.3. The Mcintosh species richness index is high everywhere (48-126), except in the Ural district (15.3). The McIntosh (0.76-0.84) and Pielow (0.80-0.91) dominance indices indicate a high level of species evenness in the mycobiota. The obtained values demonstrate the stability the document mycobiota in libraries from different regions. Significant species similarity between the districts was revealed by calculation of binary coefficients: the Jaccard coefficient was from 0.44 to 0.60; the Sørensen's qualitative measure of similarity was from 0.63 to 0.75; the quantitative similarity measure of Sørensen was from 0.44 to 0.71, and Morisita-Horn was from 0.66 to 1.0. The groups of dominant species in different regions are quite similar. The study of the ecological diversity of mycobiota on library books demonstrated the moderate diversity and the stability of the community. A high degree of similarity of taxonomic structures was established regardless of the climate conditions of the regions. Cosmopolitans characterized by high frequency of occurrence formed the major core of the library book mycobiota: Alternaria alternata, Aspergillus niger, Cladosporium cladosporioides, Mucor plumbeus, and Penicillium aurantiogriseum.

ОЦЕНКА КОРОВ-ПЕРВОТЁЛОК ЧЁРНО-ПЁСТРОЙ ПОРОДЫ ПО ДНК-МАРКЕРАМ, АССОЦИИРОВАННЫХ С ХОЗЯЙСТВЕННО-ПОЛЕЗНЫМИ ПРИЗНАКАМИ

At present time are widely used genetic markers as means in the selection of highly productive animals. Since the genes: CSN3 (kappa-casein), PIT-1 (pituitary-specific transcription factor), PRL (prolactin), GH (somatotropin) are polymorphic and encode various proteins, the study of their influence on the productive traits of cattle is relevant. In this regard, the goal of the work is to determine the influence of complex genotypes of the studied genes on the milk productivity of first-calf cows of the Black-and-White breed bred in the collective farm-breeding plant «Kazminsky» in the Kochubeevsky district of the Stavropol Territory. The place of research is the Department of Genetics and Biotechnology, VNIIOK, a branch of the North Caucasian Federal National Research Center. This article presents the results of DNA genotyping of allelic polymorphism for the CSN3, PIT-1, PRL, GH genes using PCR-RFLP methods in first-calf cows of the Black-and-White breed. It was established that these genes in the studied sample are polymorphic. The frequency of occurrence of the desired CSN3B allele in the studied sample was 0.23. The presence of alleles PIT-1A and PIT-1B of the pituitary-specific transcription factor gene was noted with a frequency of occurrence of 0.52 and 0.48. A feature of the PRL gene polymorphism was the fairly high frequency of occurrence of the PRLA allele (0.60). In this study sample of dairy cattle, the frequency of occurrence of the desired GHL allele of the somatotropin gene was 0.62. All variants of complex genotypes were also identified and their relationship with milk productivity in black-and-white cows was noted. The study sample was dominated by animals carrying complex desirable genotypes, consisting of four and three marker alleles of three and two genes (CSN3AB/PIT-1BB/GHLV; CSN3AB/PIT1AB/GHLL or PIT-1AB/PRLAB/GHLV; PIT-1AA/GHLL ) - 46.7 %. Milk yield per lactation between groups of black-and-white first-calf cows with different complex genotypes ranged from 5839.14 to 8611.33 kg. The mass fraction of fat in milk ranged from 3.93 to 4.04 %, and protein from 2.99 to 3.14 %.

Clinical effects of CYP2D6 phenoconversion in patients with psychosis.

Pharmacogenetics is considered a promising avenue for improving treatment outcomes, yet evidence arguing for the use of pharmacogenetics in the treatment of psychotic disorders is mixed and clinical usefulness is under debate. Many patients with psychosis use multiple medications, which can alter the metabolic capacity of CYP enzymes, a process called phenoconversion. In clinical studies, treatment outcomes of drugs for psychosis management may have been influenced by phenoconversion. Here we evaluate the impact and predictive value of CYP2D6 phenoconversion in patients with psychotic disorders under pharmacological treatment. Phenoconversion-corrected phenotype was determined by accounting for inhibitor strength. Phenoconversion-corrected and genotype-predicted phenotypes were compared in association with side effects, subjective well-being and symptom severity. Phenoconversion led to a large increase in poor metabolizers (PMs; 17-82, 16% of sample), due to concomitant use of the serotonin reuptake inhibitors fluoxetine and paroxetine. Neither CYP2D6-predicted nor phenoconversion-corrected phenotype was robustly associated with outcome measures. Risperidone, however, was most affected by the CYP2D6 genotype. Polypharmacy and phenoconversion were prevalent and accounted for a significant increase in PMs. CYP2D6 may play a limited role in side effects, symptoms and well-being measures. However, due to the high frequency of occurrence, phenoconversion should be considered in future clinical trials.

Fish eggs in the diet of White Sea cod Gadus morhua marisalbi (Gadiformes: Gadidae): species identification using DNA-based methods

Trophic relationships reflect the peculiarities of the functioning of communities of aquatic organisms and analysis of their structure and dynamics can be used to improve fisheries management and assess the state of marine ecosystems. Populations at the margins of the species' range have particular adaptations, including feeding habits, to extreme conditions, which makes them a convenient model object for studying the possible consequences of ecosystem changes under the influence of global factors. The cod Gadus morhua marisalbi Derjugin, 1920 permanently inhabits the coastal waters of the subarctic White Sea, located at the northeastern margin of the geographic range of the Atlantic cod G. morhua Linnaeus, 1758. This coastal cod population strongly depends on the local environmental conditions and available food resources during the summer feeding period. In addition to the main food organisms (fish, polychaetes, crustaceans), the eggs of fish spawning in shallow coastal areas in summer are also important in the diet of cod at this time. According to published data, fish eggs found in significant quantities and most often in the stomachs of cod belonged to threespine stickleback and lumpfish, but this has not been confirmed by any experimental research. Besides, the possible presence of herring eggs in the diet of cod remains unproven due to the difficulties of its visual identification. In this work, we used molecular genetic methods for species identification of fish eggs found in cod stomachs. At the first stage, the species identification of DNA isolated from eggs was done using two sets of species-specific primers: the first which we designed for the mitochondrial COI gene of stickleback, cod, and herring, and the second, published for a microsatellite locus of herring. At the second stage, the species identity of DNA extracted from fish eggs was checked using DNA barcoding. The results showed that cod stomachs contained herring and stickleback eggs, and in a number of cases we found the co-occurrence of eggs of these species. Of the 29 DNA preparations studied, fourteen were successfully amplified with microsatellite primers for herring, and thirteen amplified with primers for stickleback. Interannual differences in the occurrence of herring eggs in samples were insignificant, while the frequency of occurrence of stickleback eggs in 2018 was higher than in 2017. Our analysis did not reveal significant intra-annual differences between the observed and theoretically expected number of cases of simultaneous occurrences of herring and stickleback eggs. The high frequency of occurrence of herring and stickleback eggs in cod stomachs revealed in this study indicates the importance of these components in the diet of cod and provides new knowledge on the trophic role of cod as a key species in the White Sea ecosystem. Analysis of available data on the spatial and temporal diet patterns of coastal White Sea cod shows that fish eggs can significantly contribute to the total amount of food consumed by this species during the summer.

Research status and hotspots of tight junctions and colorectal cancer: A bibliometric and visualization analysis

BACKGROUND Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer-related death. Over the past two decades, numerous researchers have provided important evidence regarding the role of tight junction (TJ) proteins in the occurrence and progression of CRC. The causal relationship between the presence of specific TJ proteins and the development of CRC has also been confirmed. Despite the large number of publications in this field, a bibliometric study to review the current state of research and highlight the research trends and hotspots in this field has not yet been performed. AIM To analyze research on TJs and CRC, summarize the field’s history and current status, and predict future research directions. METHODS We searched the Science Citation Index Expanded database for all literature on CRC and TJs from 2001-2023. We used bibliometrics to analyze the data of these papers, such as the authors, countries, institutions, and references. Co-authorship, co-citation, and co-occurrence analyses were the main methods of analysis. CiteSpace and VOSviewer were used to visualize the results. RESULTS A total of 205 studies were ultimately identified. The number of publications on this topic has steadily increased since 2007. China and the United States have made the largest contributions to this field. Anticancer Research was the most prolific journal, publishing 8 articles, while the journal Oncogene had the highest average citation rate (68.33). Professor Dhawan P was the most prolific and cited author in this field. Co-occurrence analysis of keywords revealed that “tight junction protein expression”, “colorectal cancer”, “intestinal microbiota”, and “inflammatory bowel disease” had the highest frequency of occurrence, revealing the research hotspots and trends in this field. CONCLUSION This bibliometric analysis evaluated the scope and trends of TJ proteins in CRC, providing valuable research perspectives and future directions for studying the connection between the two. It is recommended to focus on emerging research hotspots, such as the correlations among intestinal microbiota, inflammatory bowel disease, TJ protein expression, and CRC.

Forensic characteristics of damage caused by spherical striking elements of guided multiple-launch rocket system for multiple-launch rocket system type of ammunition

BACKGROUND: Forensic aspects of blast injuries caused by the damaging elements of guided multiple-launch rocket system (GMLRS) type for MLRS ammunition are currently of particular interest because of the high frequency of occurrence and the lack of diagnostic criteria. AIM: To study the morphological features of injuries caused by spherical impactors of GMLRS-type ammunition for MLRS in conjunction with electron microscopy and elemental analysis of impactors. MATERIALS AND METHODS: The study was conducted using visual, metric methods, X-ray examination, and scanning electron microscopy (Hitachi FlexSem1000 II scanning electron microscope) with energy-dispersive X-ray analysis (Bruker Quantax 80 energy-dispersive X-ray spectrometer). RESULTS: The morphological features of injuries caused by the damaging elements of GMLRS-type ammunition for MLRS were analyzed. Scanning electron microscopy and energy-dispersive analysis made it possible to identify the characteristic chemical composition of the damaging elements. X-ray examination of corpses revealed characteristic round shadows of metallic density. CONCLUSION: The established morphological features of external and internal injuries caused by spherical damaging elements of GMLRS-type ammunition for MLRS, in combination with electron microscopy and elemental analysis, make it possible to establish, with high reliability, damage to the human body caused by the striking elements of the specified type of ammunition.

Spatiotemporal patterns in persistent precipitation extremes of the Chinese mainland (1961–2022) and association with the dynamic factors

Previous studies on extreme precipitation events have primarily focused on the intensity of such events during fixed periods, without considering the entirety of extreme precipitation events and conducting a comprehensive examination of the intensity and frequency of more disastrous persistent extreme precipitation (PEP) events. In this paper, persistent extreme precipitation indices (PEPIs) related to intensity, frequency, duration, and contribution rates were constructed, utilizing a gridded daily precipitation dataset and atmospheric circulation indices data from China for the period 1961–2022 to analyze the spatial distribution, spatiotemporal trends, and seasonal patterns and variations of PEPIs across different regions of China and the potential impact of the dynamic factors on the spatiotemporal variations of PEPIs. The results are crucial for effectively predicting future changes and informing planning for adaptation strategies: From 1961 to 2022, (1) China's PEP pattern displays distinct regional variations. PEP has been prevalent in Western Arid (Semi-Arid) Zone (WAS) and Qinghai-Tibet Plateau (QT) regions, with higher occurrence frequency, duration, and contribution rates to total extreme precipitation (44.91% and 42.01%) and overall precipitation (26.35% and 29.08%). Conversely, the humid eastern regions exhibit greater event intensity. (2) Intensity-related PEPIs show a significant increase, while the frequency and contribution rate-related PEPIs tend to decrease, indicating less frequent but more concentrated PEP events. (3) Seasonal distribution of PEP events shows a primary concentration in QT, North China (N), the Eastern arid zone (EA), and Northeast China (NE) from June to September and they occur more frequently during spring and summer in Central (C) and South China (S) regions. Summer variations predominantly account for annual PEP variability and trends. (4) WPSHII, SCSSHII, WPWPSII, APVII, NHPVII, NINO3 predominantly affect the WAS, QT, NE, C, and S regions, with WPSHII having the broadest impact, notably on the QT, C, S, and NE regions. In the WAS region during autumn, the interaction of NAO and WPSHII explains 72% of the intensity of PEP events.

Assessment of the genetic similarity between the novoaltayskaya horse breed and the original breeds by microsatellite DNA loci

The research was carried out for the purpose of a comparative assessment of the allele pool of the Novoaltayskaya horse breed and the breeds that participated in its creation. The experimental sample included 5736 horses, including: Novoaltayskaya breed – 363, Altai – 39, Lithuanian Heavy Draft – 159, Russian Heavy Draft – 617, Soviet d Heavy Draft – 288, Orlov trotter – 4,177, Budenny – 93. Population genetic analysis was performed using generally accepted methods. The following indicators were determined: the total number of alleles at 17 loci, the average number of alleles per locus, the level of polymorphism, observed and expected heterozygosity, coefficients of intrapopulation inbreeding, genetic similarity and genetic distances. It was established that horses of the Novo-Altai breed had the highest level of genetic diversity (154 alleles) and polymorphism (Ae = 4,909). Analysis of genetic differentiation showed the absence of intrapopulation inbreeding in the groups of Altai, Lithuanian Heavy Draft and Budenny breeds. Groups of horses of the Novoaltayskaya, Orlov trotter, Russian Heavy Draft and Soviet Heavy Draft breeds were distinguished by a slight deficiency of heterozygotes. It has been established that horses of the Novoaltayskaya and Heavy Draft breeds are characterized by a high frequency of occurrence of the HTG6 O allele, and the Altai breed is characterized by a high frequency of occurrence of the HTG4 M allele. A number of loci of alleles identical in spectrum to those of the Altai, Russian Heavy Draft and Soviet Heavy Draft breeds were identified in the Novoaltayskaya horse. Cluster analysis demonstrated a high level of genetic similarity of horses of the Novoaltayskaya breed with the Russian Heavy Draft (0,903) and Altai (0,899) breeds. As part of the study, using molecular genetic markers, new data was obtained on horses of seven breeds, with the help of which it is possible to improve breeding programs in horse breeding, allowing to control the biodiversity and genetic similarity of populations, preserving the originality and heterogeneity of the allele pool of horses of different breeds.

Impacts of climate change and variability on drought characteristics and challenges on sorghum productivity in Babile District, Eastern Ethiopia

ABSTRACT Examining the characteristics of drought indices in the context of climate variability and change, particularly in semi-arid water-stressed regions, requires adaptation. Observed climate data of the Babile station from 1980 to 2009 were used as a baseline for climate projection. Future climate projection was established under two Representative Concentration Pathway (RCP4.5 and RCP8.5) climate scenarios for the 21st century. Two drought indices, namely standard precipitation index and standard evapotranspiration index (SPI and SPEI) were employed based on temperature and rainfall to characterize droughts. Our study revealed that drought severity and intensity are more likely to increase under RCP4.5 climate forcing in the middle of the 21st century. The average drought severity (S) was 1.1, 1.53, 1.55, and 1.8 in SPEI 3-month time scale; 1.51, 2.1, 2.38, and 2.29 in SPEI 4-month time scale; and 2.15, 2.77, 3.44, and 2.91 in SPEI 6-month time scale, whereas, the drought severity (S) was 1.33, 1.37, and 1.79 in SPEI 3-month time scale; 1.79, 2.05, and 2.19 in SPEI 4-month time scale; and 2.47, 3.19, and 2.69 in SPEI 6-month time scale in observed, near, mid and end of the 21st century under RCP4.5 and 8.5 scenarios, respectively. Increase in drought frequency and severity occurrences under RCP4.5 scenario would have a negative impact on sorghum crop productivity. We recommended further study on practical soil water conservation to drought management in the study area.

Exploring the impact of nocturnal boundary layer stability on wintertime air pollution in a highly polluted basin city using unsupervised learning classification

This study utilizes ten years of wintertime boundary layer meteorological and surface air quality observations to characterize the nocturnal boundary layer (NBL) stability and assess its relationship with air pollution in Taiyuan, a highly polluted basin city in China. An unsupervised learning feature extraction technique known as the self-organizing map (SOM) is applied to objectively classify nocturnal virtual potential temperature (VPT) profiles. The SOM-based classification scheme allows the representation of wintertime day-to-day NBL evolutions by just nine regimes. Special attention is given to four dominant regimes: weak to moderate stability regime (NBL1), cloudy moderate stability regime (NBL3), windy moderate stability regime (NBL7), and strong stability regime (NBL9). These dominant regimes have relatively higher occurrence frequencies (>10%), with the highest frequency associated with the strong stability regime (NBL9) at 25.2%. The diurnal cycles of selected pollutants (CO, NO2, SO2, and PM2.5) exhibit significant distinctions among the different NBL regimes. For instance, in the strong stability regime, CO, NO2, and PM2.5 show explosive growth in the evening due to the accumulation of primary pollutants. However, in the cloudy moderate stability regime, PM2.5 exhibits persistent slow growth throughout the day, likely due to secondary particle formation under high humidity and high SO2 conditions. These findings enhance our understanding of NBL meteorological impacts on surface air pollution in basin cities.

Phenological gap in fruiting period and dispersal of seeds from alien fleshy-fruited plants by medium-sized carnivores in temperate forests of Central Europe

Some biological differences between native and alien plants are relevant to their dispersal mechanisms. One of them is the fruiting period: it is shifted in time, peaking later than in natives. Here we report the case study showing the temporal distance in fruiting phenology between native and alien plants and their seed dispersal via carnivorous mammals. From 2009 to 2011, scats of badgers Meles meles, foxes Vulpes vulpes, martens Martes spp. (M. martes and M. foina) and possibly also raccoon dogs Nyctereutes procyonoides (N = 820) were collected along transects totaling 30.4 km in length each month from June to November. We analyzed the frequency of occurrence of seeds (FO%) and the seed load in sampled scats; 61.7% of the sampled feces contained seeds of 18 fleshy-fruited native and alien plant taxa, and the most abundant seeds were from species with multi-seeded fruits such as Vaccinium myrtillus (94.6%), Rubus sp. (2.0%), and drupes of Prunus serotina (1.0%). The structure of dominance was characterized by seeds of Vaccinium myrtillus (15.0%), Pyrus sp. (14.8%) and Prunus serotina (13.0%) with aliens reaching high frequency of occurrence (FO%). The shares of seed FO% in the samples differed between alien and native plants. For seed load there were also significant interactions between the status of the seeds (alien or native) and the month of the vegetation period. Our data show the coincidence of two factors – the late fruiting period of alien plants and the decreasing availability of native fruits during the vegetation period. Such a set of factors may promote the dispersal of alien plant seeds by carnivorous mammals, which, unlike migrating birds, are constantly present in autumn. The limited availability of native fruits after their fruiting period, creating a phenological gap, makes alien plants the main source of fleshy-fruits at the end of vegetation period in forest ecosystems; this is expressed in high proportion of alien plants in seed FO%, and in significant interactions in the seed load in carnivore scats.

English Adjectives Used by Non-natives in ICNALE Spoken Dialogues

The purpose of this study is to examine English adjectives found in spoken language corpus of English learners in Asia. This study employed theories of adjectives from language typology perspective by Dixon (2010) and Frawley (1992). Descriptive-qualitative approach was applied, using ICNALE Spoken Dialogues as the data source. This study utilized the corpus analysis tools AntConc. The results identified the top 20 adjectives in the corpus, with Value, Human Propensity, and Difficulty each representing 20% of the findings. This study has implications for the significance of foreign language learning. Teachers can use adjectives from these categories to teach students, as they are basic vocabularies for English learners. Students are also expected to gain a better understanding of the functional aspect of adjectives, which could improve their language performance. The interest of this study lies in the high frequency of occurrence in the corpus. However, some limitations should also be considered.

감염병 발생에 대한 연령별 무질서도 및 다차원척도 분석

In this study, we crawled statistical data on 63 infectious diseases from the Korea Disease Control and Prevention Agency (KCDA) and examined the age-specific disease occurrence associations for the top 15 diseases with relatively high frequency of occurrence. Cumulative patient counts for infectious diseases were aggregated from 2001 to 2021, revealing chickenpox had the highest number of cases over the past 21 years, totaling approximately 660,000 cases. The Shannon index, reflecting disorderliness in age-specific occurrence, was highest for chickenpox, indicating concentrated disease occurrence in specific age groups. In contrast, typhoid fever showed the lowest Shannon index value, suggesting a disease with a high potential for occurrence across all age groups. Additionally, various distance metrics such as Euclidean distance, Chi-squared distance, weighted Chi-squared distance in contingency tables, and Hellinger distance were utilized to calculate the distance matrices of infectious diseases and applied multidimensional scaling. In particular, multidimensional scaling based on Hellinger distance for categorical data provided meaningful results in interpretation. According to the findings, diseases such as chickenpox, measles, mumps, and epidemic parotitis demonstrated a high occurrence frequency with a tendency for occurrence in younger age groups, forming a cluster of diseases. On the other hand, diseases like carbapenem infection, pneumococcal infection, trachoma, and hepatitis C formed a group characterized by lower occurrence frequency but occurring predominantly in older age groups.

AFLATOXIN CONTAMINATION AND NUTRITIONAL EVALUATION OF DRIED JUVENILE FISH (Clarias gariepinus) SOLD IN IBADAN METROPOLITAN MARKETS

The contamination of food due to the occurrence of mycotoxigenic fungi is a public health concern. Therefore, fungi and aflatoxin contamination of smoked-dried juvenile fish (SDJF) (Clarias gariepinus) were investigated. The samples were purchased from three major markets in Ibadan. The total fungal count ranged from 1.0 x 103 to 12.0 x 103 CFU/g. Thirty-two fungi were isolated, including Penicillium sp., Rhizopus sp., Alternaria sp., Aspergillus flavus, Aspergillus niger, and Aspergillus ochraceus. A. niger had the highest frequency of occurrence (38%), while A. ochraceus (3%) had the lowest. All the samples were contaminated with aflatoxin. The total aflatoxin content ranged from 0.237 to 1.995 ppb. Of the 11 Aspergillus strains obtained from the samples, 5 were aflatoxigenic, while 6 were not. 85 and 94% of the mycobiota were xerophilic and halophilic. The percentage moisture content, crude protein, crude fat, and ash content in the samples ranged from 12.99–17.82%, 68.72–77.62%, 0.49–6.00%, and 6.97–12.24%. Phosphorus and potassium concentrations of the SDJF samples ranged from 388.2–509.6 mg/100g and 1113.8–1517.0 mg/100g, while lead and cadmium were not detected in the samples. Though the level of aflatoxin contamination in this study was within the maximum limit permitted (20 ppb), proper attention is needed for adequate preservation before sales and consumption.

Influence of Immersion Time on the Frequency Domain Characteristics of Acoustic Emission Signals in Clayey Mineral Rocks.

The frequency domain characteristics of acoustic emission can reflect issues such as rock structure and stress conditions that are difficult to analyze in time domain parameters. Studying the influence of immersion time on the mechanical properties and acoustic emission frequency domain characteristics of muddy mineral rocks is of great significance for comprehensively analyzing rock changes under water-rock coupling conditions. In this study, uniaxial compression tests and acoustic emission tests were conducted on sandstones containing montmorillonite under dry, saturated, and different immersion time conditions, with a focus on analyzing the effect of immersion time on the dominant frequency of rock acoustic emission. The results indicated that immersion time had varying degrees of influence on compressive strength, the distribution characteristics of dominant acoustic emission frequencies, the frequency range of dominant frequencies, and precursor information of instability failure for sandstones. After initial saturation, the strength of the rock sample decreased from 53.52 MPa in the dry state to 49.51 MPa, and it stabilized after 30 days of immersion. Both dry and initially saturated rock samples exhibited three dominant frequency bands. After different immersion days, a dominant frequency band appeared between 95 kHz and 110 kHz. After 5 days of immersion, the dominant frequency band near 0 kHz gradually disappeared. After 60 days of immersion, the dominant frequency band between 35 kHz and 40 kHz gradually disappeared, and with increasing immersion time, the dominant frequency of the acoustic emission signals increased. During the loading process of dry rock samples, the dominant frequency of acoustic emission signals was mainly concentrated between 0 kHz and 310 kHz, while after saturation, the dominant frequencies were all below 180 kHz. The most significant feature before the rupture of dry rock samples was the frequent occurrence of high frequencies and sudden changes in dominant frequencies. Before rupture, the characteristics of precursor events for initially saturated and immersed samples for 5, 10, and 30 days were the appearance and rapid increase in sudden changes in dominant frequencies, as well as an enlargement of the frequency range of dominant frequencies. After 60 days of immersion, the precursor characteristics of rock sample rupture gradually disappeared, and sudden changes in dominant frequencies frequently occurred at various stages of sample loading, making it difficult to accurately predict the rupture of specimens based on these sudden changes.

Pre-contact Indigenous fire stewardship: a research framework and application to a Pacific Northwest temperate rainforest

Fire is a key disturbance process that shapes the structure and function of montane temperate rainforest in the Pacific Northwest (PNW). Recent research is revealing more frequent historical fire activity in the western central Cascades than expected by conventional theory. Indigenous peoples have lived in the PNW for millennia. However, Indigenous people's roles in shaping vegetation mosaics in montane temperate forests of the PNW has been overlooked, despite archaeological evidence of long-term, continuous human use of these landscapes. In this paper, we present a generalizable research framework for overcoming biases often inherent in historical fire research. The framework centers Indigenous perspectives and ethnohistory, leveraging theory in human ecology and archaeology to interpret fire histories. We apply this framework to place-based, empirical evidence of Indigenous land use and dendroecological fire history. Our framework leads us to conclude that the most parsimonious explanation for the occurrence of historical high fire frequency in the western Cascades is Indigenous fire stewardship. Further, our case study makes apparent that scholars can no longer ignore the role of Indigenous people in driving montane forest dynamics in the PNW.
