Oviductal fluid counterbalances the negative effect of high temperature on sperm in an ectotherm model

open access: yesBiology Open, 2021
Global warming is affecting biodiversity; however, the extent to which animal reproductive processes respond to predicted temperature increments remains largely unexplored. The thermal environment has a pronounced impact on metabolic rates of ectotherms;

The influence of environmental factors on pond activity of aquatic red-spotted newts Notophthalmus viridescens

open access: yesJournal of Freshwater Ecology, 2017
Many important components of animal behavior, growth, and reproduction are tightly linked to environmental conditions, particularly for ectothermic freshwater organisms.

Variation in Thermal Tolerance and Its Relationship to Mitochondrial Function Across Populations of Tigriopus californicus

open access: yesFrontiers in Physiology, 2019
Variation in thermal tolerance plays a key role in determining the biogeographic distribution of organisms. Consequently, identifying the mechanistic basis for thermal tolerance is necessary for understanding not only current species range limits but ...

Oxidative phosphorylation efficiency, proton conductance and reactive oxygen species production of liver mitochondria correlates with body mass in frogs [PDF]

open access: yes, 2015
ody size is a central biological parameter affecting most biological processes (especially energetics) and mitochondria is a key organelle controlling metabolism and is also the cell's main source of chemical energy.

Electroactive macromolecular motors as model materials of ectotherm muscles

open access: yesRSC Advances, 2021
The electrochemical reaction in liquid electrolytes of conducting polymers, carbon nanotubes, graphenes, among other materials, replicates the active components (macromolecular electro-chemical motors, ions and solvent) and volume variation of the ...

Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]

open access: yes, 2015
The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.

Assessing thermal ecology of herpetofauna across a heterogeneous microhabitat mosaic in a changing aridland riparian system

open access: yesEnvironmental Research: Ecology, 2023
Species–environmental relationships, including drivers of body temperature ( T _B ), are important for understanding thermal ecology and physiological needs of species during climate change.

Mitochondria and the thermal limits of ectotherms [PDF]

open access: yesJournal of Experimental Biology, 2020
ABSTRACTTemperature is a critical abiotic factor shaping the distribution and abundance of species, but the mechanisms that underpin organismal thermal limits remain poorly understood. One possible mechanism underlying these limits is the failure of mitochondrial processes, as mitochondria play a crucial role in animals as the primary site of ATP ...

Predicting the fundamental thermal niche of ectotherms. [PDF]

open access: yesEcology
AbstractClimate warming is predicted to increase mean temperatures and thermal extremes on a global scale. Because their body temperature depends on the environmental temperature, ectotherms bear the full brunt of climate warming. Predicting the impact of climate warming on ectotherm diversity and distributions requires a framework that can translate ...

Low temperatures impact species distributions of jumping spiders across a desert elevational cline. [PDF]

open access: yes, 2020
Temperature is known to influence many aspects of organisms and is frequently linked to geographical species distributions. Despite the importance of a broad understanding of an animal's thermal biology, few studies incorporate more than one metric of ...
