Climate change is most rapid in the Arctic, posing both benefits and challenges for migratory herbivores. However, population‐dynamic responses to climate change are generally difficult to predict, due to concurrent changes in other trophic levels. Migratory species are also exposed to contrasting climate trends and density regimes over the annual cycle. Thus, determining how climate change impacts...
Global warming is one of the greatest threats to the persistence of populations: increased metabolic demands should strengthen pairwise species interactions, which could destabilize food webs at the higher organizational levels. Quantifying the temperature dependence of consumer–resource interactions is thus essential for predicting ecological responses to warming.
We explored feeding interactions...
When in 1824 the French mathematician Jean Baptiste Joseph Fourier suggested that the Earth’s temperature was slowly increasing it was not readily accepted. Some years later Svante Arrhenius (1896) and Guy Callendar (1938) supported this hypothesis and added that the planet’s temperature is increasing due to man’s activities, in particular the production of CO2, which has a crucial role in this matter...
