Fitness in invasive social wasps

Figure 1: Foraging common wasp worker carrying its prey. The beech forests in Nelson Lakes National Park, New Zealand, are filled with the buzzing sound of wasps. Nests are well hidden in the ground but in this forest, they can be easily spotted by observing foraging...

The who, when, where, how and why of partial migration

We were amazed when we first heard rumours that giant tortoises migrated up and down the volcanoes of the Galapagos Islands. Darwin had first mentioned the possibility after discussing with local farmers why tortoise trails went uphill! Later, several researchers found...

Complexity and structure of food webs in the Barents Sea

A food web describes the diversity of species and their feeding relationships, i.e. "who eats whom". Food webs are essential parts of ecology as they summarize who is present in an ecosystem and how species interact with one another, here as consumer and prey. It may...

More species, more genes?

More species, more genes? Why positive correlations between species and genetic diversity might not be the rule Diversity is an essential facet of natural ecosystems that cuts through many organizational scales. The diversity of species observed in a given area (...

March cover

The photo on the cover for our March Issue was shot by Johannes Foufopoulos. A male Aegean Wall Lizard (Podarcis erhardii) photographed on the Cycladic island of Naxos (Greece). The species occurs in numerous relict populations across land-bridge islands that were...

Does density dependence matter in foraging?

When explaining animal distributions in ecosystems, ecologists have long debated the relative importance of food availability on the one hand, and density-dependence on the other. A high availability of food typically attracts and concentrates animals. Foragers may...

How do the foragers respond to masting?

Masting is the synchronous production of large seed crops across individuals within a plant population, and is thought to have evolved (at least in part) as a mechanism to escape seed predators. How does this work? Theory predicts that superabundant, synchronous seed...

Editor's choice February

Organisms respond to predation risk in multiple ways. Induced defences are not restricted to plants in response to herbivore attack, but are also prominently present in vertebrates and arthropods. Induced responses can be of behavioural or morphological origin and...

Sigmoidal function of infections

Infectious diseases that can be contracted from the environment form a persistent threat to human health, livestock and wildlife. With the changing environment, there is increasing need for predictive modelling of environmentally transmitted disease dynamics...

On carnivorous plants, seed banks, and uncertainty

Plant demographers have it easy, as the saying goes. Plants don't move and their fates may be followed through time in permanent plots - as the photo of M. Paniw, taking measurements of Drosophyllum lusitanicum in a heathland patch, shows. What happens, though, to...
