Macroscale patterns in body size of intertidal crustaceans provide insights on climate change effects
Predicting responses of coastal ecosystems to altered sea surface temperatures (SST) associated with global climate change, requires knowledge of demographic responses of individual species. Body size is an excellent metric because it scales strongly with growth and fecundity for many ectotherms. These attributes can underpin demographic as well as community and ecosystem level processes, provi...
متن کاملEnvironmental and scale-dependent evolutionary trends in the body size of crustaceans.
The ecological and physiological significance of body size is well recognized. However, key macroevolutionary questions regarding the dependency of body size trends on the taxonomic scale of analysis and the role of environment in controlling long-term evolution of body size are largely unknown. Here, we evaluate these issues for decapod crustaceans, a group that diversified in the Mesozoic. A ...
متن کاملBody-Size Regulation: Combining Genetics and Physiology
New research has revealed that the activity of the insulin-signaling pathway in the prothoracic gland of Drosophila modulates ecdysone release and thereby influences both the duration and rate of larval growth.
متن کاملThe genome sizes of ostracod crustaceans correlate with body size and phylogeny
46 47 Within animals a positive correlation between genome size and body size has been detected in 48 several taxa but not in others, such that it remains unknown how pervasive this pattern may be. 49 Here we provide another example of a positive relationship, in a group of crustaceans whose 50 genome sizes have not previously been investigated. We analyze genome size estimates for 46 51 specie...
متن کاملCombined Effects of Ocean Warming and Acidification on Copepod Abundance, Body Size and Fatty Acid Content
Concerns about increasing atmospheric CO2 concentrations and global warming have initiated studies on the consequences of multiple-stressor interactions on marine organisms and ecosystems. We present a fully-crossed factorial mesocosm study and assess how warming and acidification affect the abundance, body size, and fatty acid composition of copepods as a measure of nutritional quality. The ex...
