Effects of Climate Warming on Consumer-Resource Interactions: A Latitudinal Perspective

open access: yesFrontiers in Ecology and Evolution, 2019
There is increasing evidence that climate warming is impacting biodiversity by disrupting species interactions. Trophic (consumer-resource) interactions, which comprise the fundamental units (modules) of food webs, are of particular importance because ...

Individual Variation in Thermal Reaction Norms Reveals Metabolic-Behavioral Relationships in an Ectotherm

open access: yesFrontiers in Ecology and Evolution, 2022
Ectothermic organisms respond to rapid environmental change through a combination of behavioral and physiological adjustments. As behavioral and physiological traits are often functionally linked, an effective ectotherm response to environmental ...

Fertility loss and recovery dynamics after repeated heat stress across life stages in male Drosophila melanogaster: patterns and processes

open access: yesRoyal Society Open Science
Frequent and extreme temperatures associated with climate change pose a major threat to biodiversity, particularly for organisms whose metabolism is strictly linked to ambient temperatures. Many studies have explored thermal effects on survival, but heat-

Short-term forest management effects on a long-lived ectotherm. [PDF]

open access: yesPLoS ONE, 2012
Timber harvesting has been shown to have both positive and negative effects on forest dwelling species. We examined the immediate effects of timber harvests (clearcuts and group selection openings) on ectotherm behavior, using the eastern box turtle as a

Phenotypically Plastic Responses to Predation Risk Are Temperature Dependent [PDF]

open access: yes, 2019
Predicting how organisms respond to climate change requires that we understand the temperature dependence of fitness in relevant ecological contexts (e.g., with or without predation risk).

Patterns of activity and body temperature of Aldabra giant tortoises in relation to environmental temperature

open access: yesEcology and Evolution, 2018
We studied the temperature relations of wild and zoo Aldabra giant tortoises (Aldabrachelys gigantea) focusing on (1) the relationship between environmental temperature and tortoise activity patterns (n = 8 wild individuals) and (2) on tortoise body ...

Size Matters: Individual Variation in Ectotherm Growth and Asymptotic Size. [PDF]

open access: yesPLoS ONE, 2016
Body size, and, by extension, growth has impacts on physiology, survival, attainment of sexual maturity, fecundity, generation time, and population dynamics, especially in ectotherm animals that often exhibit extensive growth following attainment of ...

The Evolution of Endothermy and Its Diversity in Mammals and Birds [PDF]

open access: yes, 2004
Many elements of mammalian and avian thermoregulatory mechanisms are present in reptiles and the changes involved in the transition to endothermy are more quantitative than qualitative.

Effect of water temperature on the courtship behavior of the Alpine newt Triturus alpestris [PDF]

open access: yes, 2005
peer reviewedTemperature is expected to have an effect on the behavioral patterns of all organisms, especially ectotherms. However, although several studies focused on the effect of temperature on acoustic displays in both insects and anurans, almost ...

A warmer environment can reduce sociability in an ectotherm

open access: yesGlobal Change Biology, 2022
AbstractThe costs and benefits of being social vary with environmental conditions, so individuals must weigh the balance between these trade‐offs in response to changes in the environment. Temperature is a salient environmental factor that may play a key role in altering the costs and benefits of sociality through its effects on food availability ...
