The mean curved carapace length of all nesting female turtles was 98.2 cm. A total of 28 clutches …

Empowering Young Innovators Through School-Based Agricultural Education: Insights From A Nigerian Secondary School Teacher, Mary O. Olumide-Oyaniyi

National Collaborative for Research on Food, Energy, and Water Education (NC-FEW)

Nigeria faces challenges like food insecurity and economic instability, worsened by a growing youth population. School-Based Agricultural Education (SBAE) engages youth in agricultural innovations. This study implemented SBAE principles in a Nigerian school, combining poultry farming and aquaculture. Students managed a poultry farm, using chicken droppings to breed maggots as feed for catfish in rainwater-filled tanks. The project enhanced students' skills, improved local food production, and engaged the community. Despite funding and management challenges, the initiative demonstrated SBAE's potential to empower youth and advance agricultural practices, offering a model for similar projects in other regions.

Salmon As An Ecological Pathway Of Contaminants Into Alaskan Food Webs, Miranda Brohman, Gretchen Roffler, Dimitri G. Giarikos, David Kerstetter, Amy C. Hirons

SECLER Data

Salmon are important fish taxa for humans and animals in hemiboreal and subarctic ecosystems. Trace elements and their marine food web bioaccumulation raises biomagnification and potential human health risk concerns. Sixteen trace element concentrations and their health risk assessments were determined in seven different tissues of two Southeast Alaska salmon species (chum, Oncorhynchus keta and pink, Oncorhynchus gorbuscha). Chum tissues had overall higher trace element concentrations compared to pink, which may be attributed to a difference of diets, generally longer-lived and spending more time in the open ocean. All kidney and liver samples exceeded the tolerable daily intake for …

Continuous Exposure To An Aversive Mixture: A Means Of Maintaining Aversion In Sheep Averted To Geigeria Ornativa O. Hoffm. (Vermeerbos) - An Assessment, Leendert D. Snyman

Poisonous Plant Research (PPR)

Establishing aversion to Geigeria ornativa only lasts for some time, after which the induced aversion disappears and sheep start eating G. ornativa again. This behavior is aggravated by the social influence of non-averted sheep in mixed grazing situations. Exposing sheep continuously to a so-called “aversive mixture”, containing an aversive substance (lithium chloride) and the sensory characteristics of the plant (hexane extract of G. ornativa) mixed with a tasty meal (maize meal), following an initial aversion treatment, resulted in sustained aversion to G. ornativa in the field. This method proved to be applicable to mixed grazing situations with averted and …

Influence Of Inselbergs On Bat Diversity In Afrotropical Ecosystems, Amanda Lee Grunwald

Dissertations and Theses

Humans are altering biological communities on local to global scales, driving profound changes in biodiversity and ecosystem functioning. However, significant gaps and biases in biodiversity data hinder our understanding of ecosystem interactions, making it challenging to develop effective, data-driven policies to protect remaining biodiversity. Bats, the second most species-rich groups of mammals, have a global distribution, and perform a broad array of vital ecosystem functions. Their diversity peaks in the tropics, where they often constitute more than 50% of mammal species diversity. The Afrotropics host substantial bat diversity, yet have historically been perceived as having lower species richness compared to …

Transcriptional Profiles Reveal Physiological Mechanisms For Compensation During A Simulated Marine Heatwave In Yellowtail Kingfish (Seriola Lalandi), Sharon E. Hook, Ryan J. Farr, Jenny Su, Alistair J. Hobday, Catherine Wingate, Lindsey Woolley, Luke Pilmer

Fisheries Research Articles

Background

Changing ocean temperatures are already causing declines in populations of marine organisms. Predicting the capacity of organisms to adjust to the pressures posed by climate change is a topic of much current research effort, particularly for species we farm or harvest. To explore one measure of phenotypic plasticity, the physiological compensations in response to heat stress as might be experienced in a marine heatwave, we exposed Yellowtail Kingfish (Seriola lalandi) to sublethal heat stress, and used the transcriptome in gill and muscle, benchmarked against heat shock proteins and oxidative stress indicators, to characterise the acute heat stress …

Restricted Feeding Of Goats During The Last Third Of Gestation And Trans-Generational Effects On Plasma Progesterone In Their Female Offspring, Andrew A. Ponter, Bérengère Laporte, Sabine Roussel, Winai Kaewlamun, Pascale Chavatte-Palmer, Christine Duvaux-Ponter

The Thai Journal of Veterinary Medicine

Feeding levels can vary in goat farms for several reasons. Underfeeding of gestating dairy goats can occur and may influence fetal follicle development and future reproductive performance in their offspring. The objective of this experiment was to study the effect of restricted feeding during the last third of gestation on some reproductive parameters in female offspring (F1). Two feeding groups were formed using 60 Alpine and Saanen dairy goats to produce the F1 female offspring. The control group (C, n = 30) was fed to requirements. The restricted group (R, n = 30) was given the same diet, but the …

The Philippine Agricultural Scientist

Lake Batur in Bangli Regency, Bali Province is a priority area for ecological quality restoration in Indonesia due to its vulnerability to environmental changes caused by diverse and intensive utilization. Agricultural activities, fisheries, and tourism affect the lake’s water quality, leading to the uncontrolled growth of water weeds such as water hyacinth (Pontederia crassipes). To determine the relationship between water quality, community activities, and water weed presence, water samples were collected from 9 locations consisting of residential, tourist, aquaculture, and agricultural areas. In situ analysis was then conducted to measure turbidity, pH, temperature, dissolved oxygen (DO), total dissolved …

2024–2025 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

For the second year in a row, all twenty CBCs [Christmas Bird Counts] were run during the 2024–2025 season. The weather was generally cooperative, although five circles reported fog and two others had rain. Branched Oak-Seward was postponed a week due to icy conditions on the originally scheduled day. The average high temperature for all circles on count day was 41 and the average low temperature was 22. Because December had remained relatively mild, there was a good deal of open water, which encouraged many species of water birds to remain. Consequently, most of the circles reported species totals higher …

Winter Field Report, December 2024–February 2025, W. Ross Silcock

Nebraska Bird Review

Since I started a few years ago to compare each season’s reports with the status of each species as presented in BONO (Species Accounts – Birds of Nebraska – Online), I had expected that “Routine reports” would apply to an increasing number of species as the BONO database firmed up, but this hasn’t happened. My comments from last winter continue to be valid this winter, now for the third winter in a row: As was the case for winter 2022–2023, the big general story was the large number of reports of tardy fall migrants and unexpectedly northerly occurrences in mid-winter… …

Widespread Detection Of Second Generation Anticoagulant Rodenticides In Australian Native Marsupial Carnivores, Michael T. Lohr, Cheryl Anne Lohr, Judy Dunlop, Melissa Snape, Stephanie Pulsford, Evan Webb, Robert A. Davis

Research outputs 2022 to 2026

Anticoagulant rodenticides (ARs) have been detected in non-target wildlife species worldwide but information on exposure in Australian mammals is extremely limited. To address this, we analysed liver tissue from the five largest sized species of native Australian carnivorous and scavenging mammals for all SGARs currently used in Australia. A total of 52 individual animals from five dasyurid species were tested for exposure to ARs with 26 individuals (50 %) testing positive. Eleven individuals (21 %) tested positive for more than one AR compound, and two individuals tested positive for three types of AR. This study is the first to document …

Microbial Communities Associated With Endangered West Texas Springsnails And Their Potential Roles In Conservation, Russell L. Minton, Kathryn E. Perez

School of Integrative Biological & Chemical Sciences Faculty Publications

Desert springs are one of the most threatened ecosystems globally. Those in Southwestern North America support high numbers of threatened and endemic species. Human activities present the greatest threats to springs and the organisms they support. Freshwater snails in the genera Pyrgulopsis and Tryonia are two groups of such organisms, representing diverse and threatened groups of springsnails in the Southwestern United States. Desert springs also harbour unique microbial diversity that faces similar threats from water usage and freshwater habitat degradation. Understanding springsnails and the bacteria they host represent potential exemplars for interdisciplinary conservation efforts. We studied the bacterial communities associated …

Predation Of The Scorpion Hottentotta Saulcyi (Scorpiones: Buthidae) By The Long-Eared Hedgehog (Hemiechinus Auritus) (Mammalia: Eulipotyphla: Erinaceidae) In Şırnak Province, Türkiye, Rıdvan Kurt, Ersen A. Yağmur, Tarkan Yorulmaz

Euscorpius

In this study, we report the predation of Hottentotta saulcyi (Simon, 1880) by the insectivorous mammal Hemiechinus auritus (Gmelin, 1770) in Şırnak Province, southeastern Türkiye. During a nighttime field trip, we observed a long-eared hedgehog biting a H. saulcyi individual on its prosoma. This observation confirms that long-eared hedgehogs feed on and prey upon scorpions.

Current Challenges And Preliminary Morphological Reassessment Of The Genus Chaerilus Simon, 1877 In China (Scorpiones: Chaerilidae), Victoria Tang

Euscorpius

The genus Chaerilus Simon, 1877 in China is preliminarily revised on a morphological basis, derived from the available literature and newly examined specimens. The robustness of several commonly applied species-level diagnostic criteria are evaluated. Ten species are provisionally recognized for China, including one new morphospecies, Chaerilus herta sp. n., described from 9 females, 40 males, and 2 juvenile females collected in Mêdog County. The current study only reveals and resolves several most elementary issues in the taxonomy of Chinese Chaerilus. Further molecular investigations are warranted until topotypes of certain species become available.

Be Aware Of Basis Volatility When Using Price Risk Management For Calves And Feeder Cattle, Jay Parsons, Aaron Berger

Cornhusker Economics

Understanding basis volatility and the impact it has on the actual price received for calves or feeder cattle in relation to the CME Feeder Cattle Futures is important when considering price risk management opportunities. Currently, cattle markets are in a time frame where volatility appears to be like market conditions experienced in 2014 and 2015. These conditions should prompt producers to think through how basis volatility could impact the expected price they will receive for their calves or feeder cattle.
