Post-Meiotic Intra-Testicular Sperm Senescence in a Wild Vertebrate [PDF]

, 2012
There is growing interest in sperm senescence, both in its underlying mechanisms and evolutionary consequences, because it can impact the evolution of numerous life history traits. Previous studies have documented various types of sperm senescence, but

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly

Inferring Brown Bear Hair Snare Interactions by Automatically Detecting Bipedalism on Camera Trap Images Using Pose Estimation and a Multilayer Perceptron

Remote Sensing in Ecology and Conservation, EarlyView.
This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

Assessing the Hibernation Ecology of the Endangered Amphibian, Pelophylax chosenicus Using PIT Tagging Method

Animals
The Gold-spotted pond frog (Pelophylax chosenicus (Okada, 1931)), classified as an endangered species in South Korea, has experienced significant population declines due to habitat loss, primarily driven by agricultural expansion and urbanization.

Microbicidal ability across the hibernation period.

, 2013
Microbicidal ability, expressed as percent microbe killed, against E. coli (A) and S. aureus (B) in blood plasma collected from little brown myotis hibernating in the affected Aeolus Cave during the 2008–2009 hibernation period.

Artificial supplementary food influences hedgehog occupancy and activity patterns more than predator presence or natural food availability

Wildlife Biology, EarlyView.
Supplementary feeding for declining hedgehog Erinaceus europaeus populations is popular in Great Britain and has been suggested as an important factor in explaining higher densities in urban areas compared with rural ones. Occupancy modelling was used to test whether spatial variation in supplementary feeding, natural food, habitat, or predator ...

Dietary Lipids Affect the Onset of Hibernation in the Garden Dormouse (Eliomys quercinus): Implications for Cardiac Function

Frontiers in Physiology, 2018
Dietary lipids strongly influence patterns of hibernation in heterotherms. Increased dietary uptake of n-6 polyunsaturated fatty acids (PUFAs), particularly of linoleic acid (LA, C18:2 n-6), enables animals to reach lower body temperatures (Tb ...

Myocardial Hibernation in Patients with Arterial Hypertension and Ischemic Heart Disease as a Cause of Heart Failure

, 2013
Introduction. Myocardial hibernation refers to “new ischemic syndromes,” which in recent years have increasingly attracted the attention of cardiologists and cardiac surgeons.

Nocturnal neighbors: exploring residents' perceptions of urban wildlife related to animal traits identified by camera traps and literature

Wildlife Biology, EarlyView.
Wildlife in urban areas is often a source of conflict, yet relatively few efforts have been directed toward fostering coexistence in these human‐dominated landscapes. While previous research has focused on socio‐demographic factors influencing perceptions of wildlife, the role of specific animal traits in shaping acceptance remains underexplored.

Hibernating ribosomes as drug targets?

Frontiers in Microbiology
When ribosome-targeting antibiotics attack actively growing bacteria, they occupy ribosomal active centers, causing the ribosomes to stall or make errors that either halt cellular growth or cause bacterial death. However, emerging research indicates that
