On why and how to incorporate multiple interaction types into network analyses

In ecological communities, every species needs to interact with other species in order to survive and prosper. These ecological interactions are extremely varied in typology, magnitude, and mechanisms, as one would guess given the overwhelming diversity of life forms...

September cover

The cover for our September Issue relates to the paper "Plant–soil negative feedback explains vegetation dynamics and patterns at multiple scales" by Vincenot et al. Description: Simulated plant-soil negative feedback reproduces vegetation ring formation as visible in...

Editor's Choice September

The forum by Flombaum and colleagues puts the role of sampling effects for productivity maximisation central when invasions come into play. To date, most insights into the relevance and importance of biodiversity for ecosystem functioning point at the primary...

Energetic implications of environmental warming

Food webs are complex arrangements of interconnected species, with the food web of a specific ecosystem containing hundreds of species and thousands of interactions between them. From an energetics perspective, food webs can be viewed as networks of energy pathways in...

From molecules to ecosystems

Understanding only arises from organising knowledge to reveal relationships and patterns - what the Periodic Table did for chemistry. Biology is inherently difficult to organise and find general patterns. For example, different bits of biology have referred to the ‘...

Importance of food quality for extinction

In communities of competing prey species of different food quality, predators may supplement their diets of low-quality prey with high-quality prey, leading to indirect interactions between different prey species. We show that this interaction not only ensures the...

Rotifers hedge their bets against environmental unpredictability

Humans are not the only species to hedge their bets against uncertainty. No habitat is completely predictable and organisms –from microorganisms to vertebrates– living in fluctuating environments may exhibit bet-hedging strategies, which are believed to have evolved to...

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...
