The tendency of mammals to increase or decrease body size with respect to geography or
time depends on the abundance, availability, and size of resources. This dependency …

We are currently experiencing a resurgence of interest in ecogeographical rules, which
describe general trends in morphology and related traits along geographical gradients. In …

Islands have long been recognized as distinctive evolutionary arenas leading to
morphologically divergent species, such as dwarfs and giants. We assessed how body size …

The island rule is a hypothesis whereby small mammals evolve larger size on islands while
large insular mammals dwarf. The rule is believed to emanate from small mammals growing …

Along with reproduction, balancing energy expenditure with the limits of resource acquisition
is essential for both a species and a population to survive. But energy is a limited resource …

Oceanic islands have been a test ground for evolutionary theory, but here, we focus on the
possibilities for evolutionary study created by offshore islands. These can be colonized …

Aim The island rule, small animal gigantism and large animal dwarfism on islands, is a topic
of much recent debate. While size evolution of insular lizards has been widely studied …

Coastal marine ecosystems are highly productive and important for global fisheries. To
mitigate over exploitation and to establish efficient conservation management plans for …

There was previously no information on nesting, seasonal body mass or the hibernation
behaviour of the hedgehog in Ireland. Between 2008 and 2009, hedgehogs were caught …

Evolutionary theory predicts that in metapopulations subject to rapid extinction–
recolonization dynamics, natural selection should favour evolution of traits that enhance …
