Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

The Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Individual Mechanical Energy Expenditure Regimens Vary Seasonally with Weather, Sex, Age and Body Condition in a Generalist Carnivore Population: Support for Inter-Individual Tactical Diversity

Animals
Diverse individual energy-budgeting tactics within wild populations provide resilience to natural fluctuations in food availability and expenditure costs.

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

The Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Neural Code for Ambient Heat Detection in Elaterid Beetles

Frontiers in Behavioral Neuroscience, 2020
Environmental thermal conditions play a major role at all levels of biological organization; however, there is little information on noxious high temperature sensation crucial in behavioral thermoregulation and survival of small ectothermic animals such ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Behaviorally mediated, warm adaptation: A physiological strategy when mice behaviorally thermoregulate

Journal of Thermal Biology, 2014
Laboratory mice housed under standard vivarium conditions with an ambient temperature (Ta) of ~22°C are likely to be cold stressed because this Ta is below their thermoneutral zone (TNZ). Mice raised at Tas within the TNZ adapt to the warmer temperatures, developing smaller internal organs and longer tails compared to mice raised at 22°C.

Photoplethysmography for Quantitative Assessment of Sympathetic Nerve Activity (SNA) During Cold Stress [PDF]

, 2019
The differences in the degree of sympathetic nerve activity (SNA) over cutaneous blood vessels, although known to be more prominent in the periphery than the core vasculature, has not been thoroughly investigated quantitatively.
