Hybridization in a warmer world
Climate change is profoundly affecting the evolutionary trajectory of individual species and ecological communities, in part through the creation of novel species assemblages. How climate change will influence competitive interactions has been an active area of research. Far less attention, however, has been given to altered reproductive interactions. Yet, reproductive interactions between form...
متن کاملDoes a Warmer World Mean a Greener World? Not Likely!
Despite the “gloom and doom” scenarios depicted by most climate change scientists, the warmer world that we are creating can’t be all bad, can it? After all, hundreds of studies have shown that plant productivity is higher when temperatures are warmer and atmospheric carbon dioxide is high. Many models even predict an increase in global plant productivity, which has provided fodder for many to ...
متن کاملSurviving in a warmer world: environmental and genetic responses
There are numerous reports in the literature of advancing trends in phenophases of plants, insects and birds attributed to rising temperature resulting from human-driven climate warming. One mechanism that enables a population to respond rapidly to changes in the environment is termed phenotypic plasticity. This plasticity grants a degree of flexibility to enable the timing of developmental sta...
متن کاملThe costs of being big in a warmer world
Scientists first documented that animals have smaller body sizes in warmer environments back in the 19th century. Today, scientists know from laboratory studies that most ectotherms (i.e. previously called cold-blooded animals), such as fish, grow faster but to smaller maximum body sizes at higher temperatures. Yet, the mechanisms driving these patterns are somehow still unknown. Hypotheses hav...
متن کاملWill Roe Deer Persist in a Warmer World?
The Earth’s climate is rapidly changing at the hands of human activities. There is little doubt about this. There is doubt, however, about how Earth’s inhabitants will respond to this change. By combining models of expected climate change with models that match climates to the distributions of species, ecologists can project scenarios of future biodiversity. These projections are usually rather...
