What causes underwater plant collapses?

Underwater plants play a keystone role in shallow aquatic ecosystems: they stabilize clear-water conditions with high biodiversity and their decline can cause a shift to a turbid state with phytoplankton dominance. Various mechanisms have been suggested triggering...

Is phenological asynchrony associated with climate?

Trophic levels and species within them usually respond differently to global warming (Walther et al. 2002, Thackeray et al. 2010). This can lead to disruptions of many ecological interactions and, thus, different ecological processes may be altered, for instance the...

The key to success - for aliens and native species

The question why some species are rare while others are common has puzzled ecologists since decades and it has not lost any of its relevance. Especially in times of globalization, species invasions are among the most pressing issues in ecology. More recently it has...

Disturbance effects on specialists and generalists

In nature, species differ by many characteristics, such as dispersal ability, competitiveness or fecundity, that can be associated one with another. In addition, species can display distinct levels of habitat specialisation. This means that some species (‘specialist...

Does functional diversity follow changes in communities?

Ecological studies based on time-series often investigate community changes centered on species abundance or biomass but rarely expose the consequential functional aspects underlying such changes. Various measures of functional diversity (FD) gained much attention in...

Common or rare - all about the soil?

The question why some species are rare while others are common has puzzled ecologists since decades and it has not lost any of its relevance. Especially in times of globalization, species invasions are among the most pressing issues in ecology. More recently it has...

Skip the tropics to avoid malaria?

Animal migrations play a major role in our understanding of how species are distributed across space and time. Many migratory animals travel enormous distances each year, leaving us to wonder why such long migration routes are necessary. One possible explanation is the...

Does stress induce variations in mating system?

A classical hypothesis is that colonizing plants are more selfing and non-colonizing plants, found later in ecological successions, are more outcrossing. We proposed to refine this framework in the context if the Grime's CSR theory of ecological strategies. Without...

What role do monkeys play in seed dispersal?

Seed dispersal by vertebrate is a key process affecting the movement of offspring away from a parent plant. But, if plants are limited mobility, they strongly rely on the effective dispersal by vertebrates. In addition to merely transportation, fleshy-fruited plants...

Are birds faster in spring than in autumn?

In "Towards a new understanding of migration timing: slower spring than autumn migration in geese reflects different decision rules for stopover use and departure” we reveal how some birds differ from migration theory. By analyzing 65 GPS migration tracks, we showed...
