Proximate effects of temperature versus evolved intrinsic constraints for embryonic development times among temperate and tropical songbirds
Riccardo Ton, Thomas E. Martin
2017, Scientific Reports (7) 1-9
The relative importance of intrinsic constraints imposed by evolved physiological trade-offs versus the proximate effects of temperature for interspecific variation in embryonic development time remains unclear. Understanding this distinction is important because slow development due to evolved trade-offs can yield phenotypic benefits, whereas slow development from low temperature can yield...

2017, Ecology Letters (20) 539-553
Drought events are increasing globally, and reports of consequent forest mortality are widespread. However, due to a lack of a quantitative global synthesis, it is still not clear whether drought-induced mortality rates differ among global biomes and whether functional traits influence the risk of drought-induced mortality. To address these uncertainties,...
