Unofficially, it had gone by the common name Thinlip Chub. It was thought to be closely related to the two other barbeled Cyprinella species: Thicklip Chub, …

Shell Translucency: A Novel Eggshell Quality Parameter In Broiler Breeders, Duarte Neves, Austin Jasek, Colwayne Morris, Raquel Burin, Kevin Stephens, Marco Rebollo

Proceedings of the Arkansas Nutrition Conference

In the United States, nearly 240 million commercial broiler breeder eggs are incubated weekly with an average hatchability of 79.1% (Third Party Reporting). Between 160 eggs/hen and 125 chicks/hen the loss is considerable. In 2007, an estimated 1% improvement in hatchability would escalate profits by over $25 million to hatcheries and markedly increase profitability in broiler operations (Schaal and Gherian, 2007). In order to tap into top hatchability performances, egg management in commercial hatcheries such as egg storage time and conditions, incubation temperature and humidity, as well as turning frequency are of utmost importance (Vick et al., 1993; Reis et …

Turkish Journal of Veterinary & Animal Sciences

Cow behavior is a crucial indicator for monitoring health, reproductive status, and welfare in livestock management. However, methods that rely on wearable devices often face significant challenges, including high costs, maintenance difficulties, and potential impacts on animal welfare. To address these limitations, this study explored the potential of using YOLOv8, a cutting-edge computer vision model, for non-invasive monitoring of cow behavior. The research methodology involved four key steps: data collection, preliminary data processing, model training, and validation. The findings revealed that YOLOv8 is capable of accurately detecting and localizing key cow behaviors—lying, standing, eating, and ruminating—achieving a mean average precision …

Clustered Setation On The Pedipalps Of Buthid Scorpions (Scorpiones: Buthidae), Graeme Lowe, Victoria Tang

Euscorpius

Chaetotaxy of the external pedipalp femur and distal ventral pedipalp movable finger was studied in 120 species, 69 genera and 17 families of scorpions. Setation was generally denser in the ‘Buthus’ group, a major arid-adapted buthid lineage distributed across Palearctic deserts. On the external femur, macrosetae formed a prominent cluster, the ‘distal external macrosetal cluster’ (DEMC); on the distal ventral movable finger they formed a dense patch, the ‘distal ventral macrosetal cluster’ (DVMC). In other buthids and non-buthids, the DEMC and DVMC were mostly absent, except in a few arid-adapted genera. Relative setation densities of DEMC and DVMC in different …

A Multivariate Approach To Assessing Landscape Structure Effects On Wildlife Crossing Structure Use, Thomas J. Yamashita, Humberto L. Perotto-Baldivieso, David B. Wester, Kevin W. Ryer, Richard J. Kline, Michael E. Tewes, John H. Young Jr., Jason V. Lombardi

School of Earth, Environmental, & Marine Sciences Faculty Publications

Background

Complexity in landscape structure is often assessed using individual metrics related to ecological processes. However, this rarely incorporates important relationships among metrics and may miss landscape structure effects. Multivariate statistics provide techniques for assessing overall landscape structure effects. We assessed how multivariate statistics could be used to connect landscape structure with an ecological process [bobcat (Lynx rufus) wildlife crossing structure (WCS) use]. We tested how landscape structure at WCS sites compared to the surrounding landscape and how structure affected detections at WCS sites. Our study was conducted in Cameron County, Texas, USA where WCSs are in various …

Temperature Affects Nest Box Selection, Nest Success, And Nestling Size In A Southeastern Population Of Eastern Bluebirds, Katie Stumpf

Georgia Journal of Science

Given the critical role of temperature in avian reproduction, rising global temperatures will likely impact reproductive success of many bird populations. We examined the effect of nest box temperature, nest box color, entrance orientation, distance to forest cover, and distance to water on net box selection, nest success, and nestling size in eastern bluebirds (Sialia sialis) in central Georgia. White painted nest boxes had significantly cooler temperatures than control nest boxes (P < 0.05). However, model selection revealed that eastern bluebird females selected control boxes, despite their overall warmer temperatures. Nest success was associated with year, likely because of high nest predation during the warmer 2022 breeding season (P < 0.05). Nest success was also associated with cooler nest boxes, possibly because incubating females spend more time incubating which can reduce predation risks. Larger nestlings fledged from painted nest boxes, nest boxes with cooler temperatures, and nests from 2021, which we attribute to decreased thermoregulatory demands enabling faster nestling growth in cooler boxes and years. These seemingly opposing results suggest there may be an optimal temperature range where nest box temperature maximizes reproductive fitness while minimizing energetic demands on incubating adults. Determining this temperature range can help target management efforts to ensure specific goals are met.

Albinism In Olivierus Martensii (Karsch, 1879) (Scorpiones: Buthidae), Victoria Tang, Zhenbang Liu

Euscorpius

This is a formal case report for the albinism in Olivierus martensii (Karsch, 1879). Albino phenotype is compared with its normal counterpart in terms of their morphology and behavior by cursory experiments. The examined 7 albino individuals (5 of which were adults) were smaller and more slender than their normal counterparts. However, these quantitative differences were not statistically significant and should be treated with caution due to the low sample size. Their abilities to detect both white light and UV light or UV-excited fluorescence were not significantly undermined, although their tendency to ensure a clear vision through self-cleaning behavior appeared …
