Monitoring status and trends in genetic diversity for the Convention on Biological Diversity: An ongoing assessment of genetic indicators in nine countries

AbstractRecent scientific evidence shows that genetic diversity must be maintained, managed, and monitored to protect biodiversity and nature's contributions to people. Three genetic diversity indicators, two of which do not require DNA‐based assessment, have been proposed for reporting to the Convention on Biological Diversity and other conservation and policy initiatives. These indicators allow an approximation of the status and trends of genetic diversity to inform policy, using existing demographic and geographic information. Application of these indicators has been initiated and here we describe ongoing efforts in calculating these indicators with examples. We specifically describe a project underway to apply these indicators in nine countries, provide example calculations, address concerns of policy makers and implementation challenges, and describe a roadmap for further development and deployment, incorporating feedback from the broader community. We also present guidance documents and data collection tools for calculating indicators. We demonstrate that Parties can successfully and cost‐effectively report these genetic diversity indicators with existing biodiversity observation data, and, in doing so, better conserve the Earth's biodiversity.

Diversity, Composition and Abundance of Avian Species of Oxbow Lake and Surrounding Area in Purbasthali, West Bengal, India

Purbasthali oxbow lake is an important habitat for thousands of migratory and resident avian species. This study aimed to determine the current status of avifaunal diversity of Purbasthali oxbow lake and its surrounding area. During this study, diversity, composition and abundance, feeding guilds and the relationship between their habitat preferences and the numbers of individuals were determined. Direct observation, line transects and point count methods were applied for bird surveys for three consecutive years from 2019 to 2022. A total of 145 species of birds were documented, belonging to 19 orders and 49 families. Among the total species, 57 are migratory in nature and 47 are showing declining global trend. Quantitative diversity estimation were performed during the study are the Shannon-Weiner index, Simpson's Diversity Index, Shannon equitability index and relative diversity. Density and diversity of avian species was highest during post-monsoon and lowest in pre monsoon. This indicates the winter assemblages of many migratory birds choose this lake as their feeding and resting grounds.

Food Insecurity and Dietary Diversity of the Vulnerable Group in Nigeria: Drivers and Coping Strategies

The vulnerable group is the most prone to artificial or natural shocks, which could expose them food insecurity. Yet, there exists a dearth of practical information on their dietary diversity and food security status. This study, therefore, assessed the food security status and dietary diversity of the vulnerable group of Fadama III Additional Financing in Nigeria. Primary data collected from 165 respondents were analyzed using descriptive statistics, cost-of-calories, logit model, household dietary diversity score and Tobit model. The results revealed that the vulnerable group was aged smallholder farmers with a low average monthly income of N13,718 (USD 37.13). The majority (88.5%) were food insecure, while only 11.5% met the daily calorie intake of 2,260 kcal per capita. Educational level, income, and value of productive assets positively influenced their food security status, while household size negatively impacted them. Most of the vulnerable group had low dietary diversity, with a range of 0.31 to 0.40, indicating poor nutrition among them. The determinants of dietary diversity among them were gender, educational level, and household size. The most commonly employed food insecurity coping strategies were allowing children to eat first, collecting food from the wild, selling assets to buy food, eating once a day and purchase food on credit. This study suggests policy measures for educating the vulnerable group ,providing production assets and better family planning for the vulnerable group to enhance their dietary diversity and food security.

A U.S. National Study of Family Resilience During the COVID-19 Pandemic.

The COVID-19 pandemic has significantly disrupted the lives of children and their caregivers. Recent research has examined the impact of the pandemic on child and caregiver functioning but there is a paucity of work examining the impact of the pandemic on the broader family system. The current study examined family resilience during the COVID-19 pandemic across three aims: Aim 1 tested whether meaning, control, and emotion systems form a unitary family adaption factor, Aim 2 evaluated a concurrent model of family resilience, and Aim 3 examined whether parent gender and vaccination status moderated paths in the final model. A nationally representative sample of U.S. parents (N = 796; 51.8% fathers, M age = 38.87 years, 60.3% Non-Hispanic White) completed a cross-sectional survey about themselves and one child (5-16 years old) between February-April 2021, including measures of COVID-19 family risk and protective factors, pre-existing family health vulnerabilities, race, COVID-19 stressors, and family adaptation. Confirmatory Factor Analysis demonstrated that the meaning (i.e., family making meaning of COVID-19), control (i.e., stability in routines), and emotional (i.e., family support) facets of family adaptation are unique but related. A path model revealed that there were concurrent effects from COVID-19 exposure, pre-existing vulnerabilities, and racial diversity status to the family protective, vulnerability, and adaptation variables. Additionally, parent COVID-19 vaccination status altered the association between pre-existing family health vulnerabilities and the family protective factor. Overall, results underscore the importance of examining pre-existing and concurrent risk and protective factors for family resilience during a stressful, global, and far-reaching event.

Vegetation composition, diversity, stand structure, and carbon storage of Lolkisale Village Land Forest Reserve in the Northeastern part of Tanzania

Abstract. Mwakalukwa EE, Mwakisu A, Madundo S, Maliondo SMS. 2023. Vegetation composition, diversity, stand structure, and carbon storage of Lolkisale Village Land Forest Reserve in the Northeastern part of Tanzania. Nusantara Bioscience 15: 79-90. Little is known about the effects of human activities on the condition of the Lolkisale Village land Forest reserve located in Monduli District, Arusha region, in the northeastern part of Tanzania. This study assessed the status of woody species diversity, composition, structure, and available potential of the forest on carbon storage. The vegetation data were collected from 33 concentric sample plots of 5 m, 15 m, and 20 m radius laid systematically across the forest area of 960 ha. A total of 58 plant species belonging to 30 families were identified. Diversity indices have indicated a high woody species diversity in the forest reserve. The most important species were Commiphora schimperi (O.Berg) Engl., Dombeya rotundifolia (Hochst.) Planch., Acacia tortilis (Forssk.) Hayne, and Combretum molle R.Br. ex G. Don. Stand structure comprises 190 ± 117 stems ha-1, basal area of 7.68 ± 5.17m2ha-1 and standing volume of 64.04 ± 45.85 m3ha-1, while the mean above-ground carbon stocks and the mean below-ground carbon stocks were 19.55 ± 13.38 Mg C ha-1 and 3.91 ± 2.68 Mg C ha-1 respectively. Generally, the reserve was found to be in good condition. The observed high diversity of woody species signifies the importance of legally protecting this area as a village land forest reserve. In addition, quantifying other carbon pools, such as soil, dead wood, and surface litter, should be considered for estimating this forest's total carbon stock potential. In this regard, measures to control the use of the forest as a grazing area would be useful to allow new regrowth and young trees to attain maturity stages without being interfered with by the livestock.

Species Diversity, Structure, and Regeneration Status of Woody Plants in Saleda Yohans Church Forest, South Wollo, Ethiopia.

The study was conducted to determine woody plant species composition, structure, and regeneration status in Saleda Yohans Church forest, South Wollo Zone, Ethiopia. Five transect lines oriented to north-south directions at a distance of about 500 m were laid down along transects across the forest. Fifty main plots of 20 m × 20 m were laid for tree/shrub data collection. Within each main plot, 5 small quadrats of 5 m × 5 m were laid in the corners and centre for the collection of seedling and sapling data of woody species. All vegetation data within the plots were counted and recorded. Tree height and diameters at the breast height of plants were also measured and estimated. Moreover, frequency, basal area, diversity, evenness, and other vegetation data were analyzed. The result showed that this Church forest is composed of 50 woody plant species distributed in 31 families. The Shannon-Wiener diversity index and evenness values of the forest were found to be 3.82 and 0.84, respectively. Lamiaceae was the dominant family followed by Fabaceae in their species composition. The density of trees/shrubs, saplings, and seedlings was 625, 650, and 935 ha-1, respectively. Based on the result, the entire vegetation of Saleda Yohans Church forest is in good regeneration status. In conclusion, although this Church forest appears to be in a good regeneration status, its species richness is low compared to a similar study of some other vegetation. Therefore, attention should be given to the rehabilitation of this forest.

Length–Weight Relationships and Diversity Status of Fishes in the Midstream of the Jialing River, a Tributary of the Upper Yangtze River, China

The study described the length–weight relationships (LWRs) and diversity status of fishes in the midstream of the Jialing River, which is the largest tributary of the upper Yangtze River, China. A total of 4592 specimens from 53 fish species belonging to three orders and eight families were collected from December 2021 to November 2022. The results showed that Culter oxycephaloides, Xenocypris davidi, Hemibarbus labeo, Hemiculter tchangi were dominant fish species in the study region. Twenty-five fish species (IRI ≥ 10) were subjected to LWR analysis, and the regression parameters a and b for fish species varied from 0.006 to 0.333 and 2.129 to 3.391. Eleven fish species were determined to have isometric growth, and 14 fish species were determined to have allometric growth. The diversity analyses suggested that the diversity status of fishes were kept relatively stable during the sampling period and that the fishes suffered moderate disturbance in the midstream of the Jialing River. The present study provided basic biology data for fish conservation and management after the fishing ban in the Jialing River.

Diversity, endemism, indigenous uses and threat status of medicinal plants in Shivalik Hills of Himachal Pradesh, North Western Himalaya, India

Indian Himalayan Region is known globally since the Vedic time for its rich resources. Due to less accessibility to basic facilities, communities of the Himalaya are well adopted with forests for curing various ailments. The present study has been conducted in Shivalik Hills of Himachal Pradesh. A total of 330 medicinal plants belonging to 85 families and 263 genera were recorded. 40 species were native to the Himalayan Region and 27 species were native to the Himalayan Region and other biogeographical regions, together, 01 species was endemic, 23 species were near endemic. Leaves, roots and whole plants were utilized in majority of cases. The analysis revealed that maximum species were used for fever, skin diseases, cough, dysentery and stomach problems. Acorus calamus, Berberis asiatica, Cheilocostus speciosus, Cinnamomum tamala, Gloriosa superba, Pittosporum eriocarpum, Rauvolfia serpentina, Terminalia chebula, etc. were identified as threatened species. Due to habitat degradation, biological invasion, over-exploitation and changing environmental conditions, the populations of these medicinal plants are facing high pressures. Therefore, identification of Medicinal Plants Conservation Areas (MPCAs), frequent monitoring of habitats, extraction trend of medicinal plants, education, awareness and participation of the local inhabitants have been suggested.

Ecological impact assessment of dam construction: A case study of Diamer Basha Dam Gilgit‐Baltistan, Pakistan

AbstractDam construction poses significant ecological impact, both during the initial construction phase and long after the dam is completed. The Diamer Basha Dam, situated on the River Indus in the Gilgit‐Baltistan district of Pakistan, is receiving significant attention due to the ecological consequences of the proposed and ongoing construction. The Dam is a 272‐m‐tall reservoir with a 9867.912 Mm3 (million cubic meter) capacity and will be the world's highest roller compact concrete dam. The assessment of local ecological impacts was compiled in a checklist and matrices format to discuss the impacts on the status of species diversity in the study area. Using a random sample methodology, line transects, and quadrats were employed to evaluate phytosociological properties of vegetation. The floral parameters recorded were percent cover, species richness, vegetation composition, frequency, and density. The ecological analysis included principal component analysis to compare the distributions of sustained and lost vegetation in response to water flow variables. This research showed that several plant species withstand periods of high peak flow, like Salix tetrasperma, Rumex dentatis, Trifolium resupinatum, and Polygonum. Additionally, visual observations, plot surveys, transects, and published reports were used to compile the faunal data used to determine habitat distribution. According to the analysis, immediate effects of dam construction activities such as blasting, quarrying, and traffic noise cause severe disturbances to existing biodiversity and habitats with high ecological vulnerability, and have long‐term effects on ecological integrity and environmental health in downstream and upstream habitats. The study presents the present status of biological and ecological conditions, as a baseline reference datum for a comparative analysis of the changes caused by the dam's construction.

Genetic diversity and IUCN Red List status.

The International Union for Conservation of Nature (IUCN) Red List is an important and widely used tool for conservation assessment. The IUCN uses information about a species' range, population size, habitat quality and fragmentation levels, and trends in abundance to assess extinction risk. Genetic diversity is not considered, although it affects extinction risk. Declining populations are more strongly affected by genetic drift and higher rates of inbreeding, which can reduce the efficiency of selection, lead to fitness declines, and hinder species' capacities to adapt to environmental change. Given the importance of conserving genetic diversity, attempts have been made to find relationships between red-list status and genetic diversity. Yet, there is still no consensus on whether genetic diversity is captured by the current IUCN Red List categories in a way that is informative for conservation. To assess the predictive power of correlations between genetic diversity and IUCN Red List status in vertebrates, we synthesized previous work and reanalyzed data sets based on 3types of genetic data: mitochondrial DNA, microsatellites, and whole genomes. Consistent with previous work, species with higher extinction risk status tended to have lower genetic diversity for all marker types, but these relationships were weak and varied across taxa. Regardless of marker type, genetic diversity did not accurately identify threatened species for any taxonomic group. Our results indicate that red-list status is not a useful metric for informing species-specific decisions about the protection of genetic diversity and that genetic data cannot be used to identify threat status in the absence of demographic data. Thus, there is a need to develop and assess metrics specifically designed to assess genetic diversity and inform conservation policy, including policies recently adopted by the UN's Convention on Biological Diversity Kunming-Montreal Global Biodiversity Framework.

Undernutrition and Associated Factors among HIV-Infected Adults Receiving ART at Health Centers, Lega Tafo and Surrounding, Ethiopia, 2021

Background: Globally, 38 million people were living with HIV in 2019. In Africa, 25 million people are living with HIV/AIDS undernutrition and food insecurity is endemic. Hence, the study aimed to assess the magnitude of undernutrition and associated factors among HIV-infected adults receiving ART. Methods: Institutional based cross-sectional study was conducted among HIV/AIDS patients who followed the ART service was selected by a simple random sampling method. The data were collected by direct interview, using a structured questionnaire. Descriptive statistics and a logistic regression model were employed. Result: The study revealed that the magnitude of undernutrition was 18.8%. The history of opportunistic infection (AOR=4.518:95% CI: 2.304-8.857), Patients taking ART for less than one year (AOR=3.675:95% CI: 1.831-7.377) household food insecure (AOR= 3.113:95% CI: 1.628-5.950) and dietary diversity score (AOR=2.340:95% CI: 1.221-4.485) were found to have a statistically significant association with undernutrition. Conclusion: The magnitude of undernutrition among people living with HIV/AIDS was found to be high. Having an opportunistic infection, duration of taking ART treatment, household food security status, and dietary diversity status were found to statistically significant association with undernutrition.

Status of diversity, abundance and seasonal variations of gill net catches of cichlids in Lake Bosumtwi, Ghana

The cichlids in Lake Bosumtwi are under increasing pressure with a recent build-up in local fishing pressure. This study was conducted to assess the status and seasonal catch rates of fish species using gillnets over a two-year period. Four species and one introduced fish belonging to the Cichlidae family were encountered in the study. Coptodon discolor (Günther, 1903) was the most abundant species, making up 75.5% of the total fish caught (100.1 kg). Tilapia busumana (Günther, 1903) was the least abundant species, representing only 0.6% of biomass. Catch per unit effort was significantly affected by seasonality; however, species diversity, richness and evenness were not influenced by seasonal variations. The highest catch rates (975.62 g net−1 night−1) were recorded in the minor wet season (August to November). No statistical differences were detected in the diversity indices estimated for all three seasons of study. The key physico-chemical parameters (conductivity, salinity, temperature and pH) measured were within the tolerance range for tilapia survival and growth, with the exception of dissolved oxygen that decreased below 3 mg l−1 during the lake’s deep mixing events in August. Overall, physico-chemical factors explained 75% of fish catches, with salinity levels correlating significantly with catch per unit effort.

Amphibians of Rwanda: Diversity, Community Features, and Conservation Status

The diversity and distribution of the amphibians in Rwanda was critically reviewed to provide a reliable species inventory for informed conservation management. The checklist of the amphibian species of Rwanda is based on results of our own fieldwork, historical records compiled from the literature, and examination of voucher specimens in museum collections. A total of 62 species are recorded, and 22 further species listed in field guides and open-access data bases are discussed, identified as erroneous records, and consequently not included in the country list. We provide diagnostic characters of external morphology and the advertisement call for each validated species, and a short synopsis of geographic distribution, altitudinal range, occurrence in the provinces of Rwanda, and habitat preference. We provide keys to all genera, and all taxonomically described species based on morphological characters and additional keys based on features of the advertisement calls. We discuss features of amphibian communities including local community structure and delimitation of altitudinal metacommunities. Based on the IUCN red list assessment and our field surveys, we propose for the first time a national red list of amphibians in Rwanda.

The land snail family Clausiliidae (Gastropoda, Pulmonata, Stylommatophora) in Georgia: overview, novel records and a new species

The Caucasus ecoregion is one of the most important biodiversity hotspots in western Eurasia. Georgia is situated in the middle of this area, between the ranges of the Greater and Lesser Caucasus, a position providing exceptionally balanced environmental conditions for its flora and fauna. Animal groups of low mobility, such as land snails, are important indicators of the past and present geographic and climatic events shaping these unique ecosystems. We give an overview of the land snail family Clausiliidae in Georgia that includes 30 species, among which eight are endemic to this country. Their distribution areas are reassessed in the light of novel georeferenced occurrence data resulting from recent field work. Aspects of the origin, diversity, habitat requirements and conservation status of the Georgian Clausiliidae fauna are discussed. Additionally, Mucronaria (Mucronaria) kartvelica sp. n. is described from the Racha-Lechkhumi and Kvemo Svaneti Region.

New analysis of the endemic vascular plants of Algeria, their diversity, distribution pattern and conservation status

In this study, we provide a new analysis on strict-endemic vascular plant taxa of Algeria and discuss their taxonomic diversity, geographical distribution and conservation status, based on a large literature review and our own field observations. Overall, 248 taxa (species, subspecies and varieties) are currently considered as Algerian endemics, from 41 families and 128 genera. They constitute about 6.3% of the total known flora of Algeria. The northern floristic regions are richer in endemic species: K1, K2, AS3, C1+C2 and O1 are by far the richest floristic regions for strict-endemic taxa, highlighting the importance of their mountain ranges. Most (59%) of the endemic plants have a narrow geographical distribution range (range-restricted). An overview of the IUCN conservation status of the Algerian endemics indicates that only 16 taxa (6.4%) are evaluated, out of which 5.6% of the taxa are threatened. Overall, 44% of the Algerian endemics are legally protected and 43% are included in the protected areas network. Finally, we focus on the shortfalls of knowledge that could orient further research on endemism data in Algeria. They concern taxonomic, chorological or conservation figures and above all the actual presence of the endemic species. It is, therefore, urgent to carry out targeted field expeditions in order to find and re-collect these species, most of which are strictly localized and have probably never been searched or found for 60 years to over a century.

Food consumption diversity and nutritional status among children aged 6-23 months in Indonesia: The analysis of the results of the 2018 Basic Health Research.

Stunting among children under five years of age is among the highest in Indonesia. The objective of this study was to investigate the association between food consumption diversity and nutritional status among children aged 6-23 months in Indonesia. The data used came from the results of the 2018 Basic Health Research. The main independent variable was the diversity of food consumption. Control variables included breastfeeding practices and demographic and socioeconomic factors. Using ordinal logistic regression, the role of food consumption diversity in influencing nutritional status was examined after controlling for breastfeeding practices and demographic and socioeconomic factors. The results of the study showed that the diversity of food consumption (AOR = 1.15; 95%CI: 1.07-1.24) significantly and statistically influenced nutritional status of children age 6-23 months in Indonesia even after controlling for the effects of breastfeeding practices and demographic and socioeconomic factors. Higher odds of having normal nutritional status compared to being stunted or severely stunted was associated with consuming food according to the dietary diversity. Higher odds of having normal nutritional status compared to being stunted or severely stunted was also significantly and statistically associated with being ever breastfed (AOR = 1.33; 95%CI: 1.22-1.46), aged 6-11 months (AOR = 3.07; 95%CI: 2.79-3.38), female (AOR = 1.35; 95%CI: 1.25-1.46), children of non-working mothers (AOR = 1.12; 95%CI: 1.04-1.21), children of higher educated mothers (AOR = 1.50; 95%CI: 1.30-1.72), children from higher wealth quintile households (AOR = 1.65; 95%CI: 1.44-1.85), children from smaller size family (AOR = 1.07; 95%CI: 1.05-1.10), and urban children (AOR = 1.16; 95%CI:1.08-1.25). A profound percentage of children aged 6-23 months in Indonesia experienced stunting and severely stunting. Children who did not receive minimum dietary diversity were more likely to suffer from stunting. The findings from this study suggest that to ensure the achievement of national goal of preventing stunting and sustainable development goal of ending all forms of malnutrition in Indonesia, the strategy should promote the fulfillment of minimum food consumption diversity.

Rojolelo Forest Park (TAHURA) is a green open space in Central Bengkulu Regency. The research aimed to determine the species, diversity, and conservation status of birds in the Rojolelo Forest Park (TAHURA) Central Bengkulu Regency. The research was conducted February-April 2022 in three locations such as Shrubs, Irrigation dan TAHURA Office. The sample used point counts method. The Research showed 33 bird species from 21 families and 115 individuals, the diversity index (H’) = 3, 01. The family most commonly was founded Nectariniidae (4 species). Five bird species were protected such as Meiglyptes tukki (Buff-necked woodpecker), Eurylaimus ochromalus (Black and yellow broadbill), Ictinaetus malayensis (Black Eagle), Spilornis cheela (Crested serpent Eagle), and Pitta sordida (Hooded Pitta).

Diversity, Distribution, Systematics and Conservation Status of Podocarpaceae

Among conifer families, Podocarpaceae is the second largest, with amazing diversity and functional traits, and it is the dominant Southern Hemisphere conifer family. However, comprehensive studies on diversity, distribution, systematic and ecophysiological aspects of the Podocarpaceae are sparse. We aim to outline and evaluate the current and past diversity, distribution, systematics, ecophysiological adaptations, endemism, and conservation status of podocarps. We analyzed data on the diversity and distribution of living and extinct macrofossil taxa and combined it with genetic data to reconstruct an updated phylogeny and understand historical biogeography. Podocarpaceae today contains 20 genera and approximately 219 taxa (201 species, 2 subspecies, 14 varieties and 2 hybrids) placed in three clades, plus a paraphyletic group/grade of four distinct genera. Macrofossil records show the presence of more than 100 podocarp taxa globally, dominantly from the Eocene-Miocene. Australasia (New Caledonia, Tasmania, New Zealand, and Malesia) is the hotspot of living podocarps diversity. Podocarps also show remarkable adaptations from broad to scale leaves, fleshy seed cones, animal dispersal, shrubs to large trees, from lowland to alpine regions and rheophyte to a parasite (including the only parasitic gymnosperm-Parasitaxus) and a complex pattern of seed and leaf functional trait evolution.
