A University of Illinois team found tropical birds can handle thermal variation, disproving the climate variability hypothesis. The study, which measured metabolic rates across a range of temperatures, suggests that birds in the Neotropics may be more resilient to warming than previously thought.
Researchers have created the DEBBIES dataset to enhance understanding of cold-blooded animals' responses to novel environmental shifts. The dataset contains estimates of eight life history traits for 185 ectotherm species, allowing users to develop general predictions on animal responses using a few key characteristics.
A new study from North Carolina State University reveals that carrying pollen increases the body temperature of bumble bees, potentially putting them at risk due to rising environmental temperatures. The research has significant implications for bumble bee populations and ecosystems, particularly in areas experiencing climate change.
Researchers found that endotherms have well-developed turbinates and larger nasal cavities than ectotherms, helping to cool their brains. This discovery sheds light on the evolution of nasal cooling in warm-blooded animals from their theropod dinosaur ancestors.
Researchers at North Carolina State University found that ants do not adjust their behavior in response to rising temperatures, persisting in sub-optimal microhabitats. The study suggests that ants may not be able to adapt to warmer ecosystems, with potential implications for forest ecosystems.
A new study reveals that global warming can lead to an exponential increase in heat injury accumulation for ectothermic organisms, with temperatures exceeding their tolerance level resulting in severe injuries. The rate of heat injury doubles for each degree the temperature rises.
A University of Liverpool study found that ant colour and size are strongly influenced by their environment, with larger bodied ectotherms with dark colouration thriving in cold places. The study also revealed that ants adapt to changing temperatures by shifting from darker to lighter colours and smaller body sizes.
A recent study found that ectothermic animals have limited ability to acclimate to increasing temperatures, making them vulnerable to global warming. The research suggests that these animals will need to rely on behavioral or evolutionary changes to survive as temperatures rise.
Scientists at the University of Granada have confirmed Bergmann's rule for ectotherms, revealing that long-tailed lizards are larger and retain heat longer in high-altitude habitats. This study resolves decades-long debates on the mechanism behind the Bergmann clines, showing that larger animals indeed have slower cooling rates.
