Climate change is altering the phenology of species across the world, but what are the
consequences of these phenological changes for the demography and population dynamics …

There are multiple observations around the globe showing that in many avian species, both
the timing of migration and breeding have advanced, due to warmer springs. Here, we …

Migration, broadly defined as directional movement to take advantage of spatially distributed
resources, is a dramatic behaviour and an important component of many life histories that …

There is mounting evidence that global climate change has extended growing seasons,
changed distribution patterns, and altered the phenology of flowering, breeding, and …

Behaviour under conditions of mild stress shows consistent patterns in all vertebrates:
exploratory behaviour, boldness, aggressiveness covary in the same way. The existence of …

Ecological processes are changing in response to climatic warming. Birds, in particular,
have been documented to arrive and breed earlier in spring and this has been attributed to …

Climate is a major determinant for the phenology, physiology, distribution and interactions of
plants. The world's recent climate has shown a substantial increase in average temperature …

Migrant birds have been trapped on the island of Helgoland (southeastern North Sea) since
1909, with methods and sampling effort remaining unchanged throughout the last four …

Many organisms fail to adjust their phenology sufficiently to climate change. Studies have
concentrated on adaptive responses within localities, but little is known about how latitudinal …

Across a range of organisms, related species or even populations of the same species
exhibit strikingly different scales and patterns of movement. A significant proportion of the …
