A Meta-Analysis of Quantitative Collecting Techniques for Spiders
Quantitative sampling of organisms is often used to provide information in ecological studies, monitor populations, and aid in biodiversity projects. Many studies involve the quantitative sampling of spiders. In this meta-analysis study, 207 peer-reviewed journal articles formed the basis of an initial data set for a quantitative analysis of spider collection techniques. Data collected included country of study, mode of study, trapping techniques used, spider diversity, and number of specimens collected. Our meta-analysis gathered research articles that included 33 different countries of study. Trapping techniques greatly vary depending on the habitat in which spiders dwell. These were divided into aerial, arboreal, terrestrial, and subterrestrial. From the gathered data, 5% of the articles included aerial trapping, 20% included arboreal trapping, 1% included subterrestrial trapping, and 80% included terrestrial trapping. 60% of the terrestrial studies utilized pitfall trapping, 20% used hand collecting, 15% used sweep netting, and 5% used branchbeating.https://scholarworks.moreheadstate.edu/celebration_posters_2022/1033/thumbnail.jp
Survey of Spiders within Eastern Kentucky
Biodiversity is known to be the variation of living organisms compromising several levels, beginning from genes, then species, communities, then finally ecosystems. Biodiversity is crucial in maintaining ecological balance, boosting ecosystem productivity, and determining the quality of ecosystem services such as pest management in agriculture. Being aware of biodiversity\u27s importance can also help with the prevention of continuous threats to biodiversity and be best prepared to manage conservation challenges. Typically, mammals, birds, and plants are used to assess biodiversity. However, spiders may be effective in indicating environmental change because they are taxonomically quite diverse, species fill a variety of ecological niches, and they are easy to trap. Spiders can also be very numerous and reflect the heterogeneity of their environment. We assessed spider biodiversity within Eastern Kentucky using pan traps, net hunting, and sifting leaf litter. We have collected a couple thousand spiders so far and identified spiders from 20 families, including Agelenidae (grass spiders), Antrodiaetidae (Folding door Spiders), Anyphaenidae (ghost spiders), Araneidae (orb-weaver spiders), Atypidae (pursueweb spiders), Clubionidae (sac spiders), Ctenizidae (trapdoor spiders), Dictynidae (mesh web spiders), Dysderidae (Woodlouse Spiders), Hahniidae (dwarf sheet spiders), Linyphiidae (money spiders), Lycosidae (wolf spiders), Oxyopidae (lynx spiders), Philodromidae (running crab spiders), Pholcidae (cellar spiders), Pisauridae (nursery-web spiders), Salticidae (jumping spiders), Tetragnathidae (long-jawed orb weaver spiders), Theridiidae (tangle-web spiders), and Thomisidae (crab spiders). Most spiders that were found are Wolf Spiders (Lycosidae) whereas Antrodiaetidae (folding door spiders) and Atypidae (pursue-web spiders) were very rare. We have also discovered 3 genera of tarantula cousins.https://scholarworks.moreheadstate.edu/celebration_posters_2022/1032/thumbnail.jp
Nutrient Intakes among Brazilian Children Need Improvement and Show Differences by Region and Socioeconomic Level
Brazil is the most populous country in South America. Using 24 h dietary data, we compared the nutrient intakes of 4–13-year-olds to reference values and tested for regional and socioeconomic (SES) differences. A considerable proportion reported intakes below the Estimated Average Requirements (EAR) for vitamins E (78.1%, 96.5%), D (100% for both), and calcium (80.5%, 97.7%) for 4–8 and 9–13-year-olds, respectively. Few exceeded Adequate Intakes (AI) for potassium or fiber. Older children reported greater inadequacies and, while there was regional variability, patterns of inadequacy and excess tended to be similar. For vitamin C, the percent of children below EAR in the Northeast and Southeast was lower than in the South. Most children, regardless of SES, had energy intakes within the Acceptable Macronutrient Distribution Ranges (AMDRs) for carbohydrates and protein. Over a quarter reported total energy from fat less than the AMDR, and inversely associated with SES (low 50.9%, moderate 26.0%, and high 15.0%), but also exceeding the percentage of energy recommendation for saturated fat, increasing with SES (low 18.1%, moderate 38.9%, and high 48.8%). The contrast observed between the diets of young Brazilians and recommendations underscores the need for individual and regional environmental interventions to promote healthier dietary patterns
