On Mixotrophy

Bacteria appear not to be aware of the paradigm shift in the 'microbial loop'. There is a new player in the game, he is pigmented, he is efficient, he is flexible - 'The Mixotroph'." Read more about the success of mixotrophs, here http://onlinelibrary.wiley.com/doi/10...

What happens when the neighbour is eaten?

An important current focus in ecology is to better understand how species interactions can change in response to biotic and abiotic contexts. Herbaceous plants in many forests of the world face increased impacts from growing ungulate herbivore populations. However not...

Field work at home - in the tropics

Most biologists in temperate countries wonder how it is to study ecological systems in megadiverse tropical countries. Yes, it is thrilling, a true privilege. By walking in pristine tropical forests, savannas, and grasslands sometimes you have a sensation similar to a...

Species richness and biomass-how are they related?

Figure 1: More diverse assemblages of herbivores, like these algal grazers living on seagrass, produce more grazer biomass. Hundreds of experiments have shown that changes in species richness affect the biomass of a species assemblage. Have they converged on a single...

Welcome EriK T Aschehoug - new SE

We are very happy to welcome Erik T Aschehoug from Louisiana State University in Baton Rouge. Get to know him on his website: http://aschehouglab.com/about.html and in my interview with him: What's your main research focus at the moment? Most of my work is focused on...

INTEGRATING TOOLS OF ECOLOGICAL STOICHIOMETRY AND NUTRITIONAL GEOMETRY

Background: ES/NG working group at Woodstoich III Upon meeting at the Woodstoich III workshop in Sydney, Australia in the summer of 2014, we and four other working groups sought to explore connections between ecological stoichiometry (ES), nutritional geometry (NG),...

Coexisting or not coexisiting? That's the....

A lot of species coexist. A lot don’t. Distinguishing between the two groups is a core component of community ecology. The inherent complexity of natural systems, and the quantity of data needed to fill in theoretical models, makes species coexistence particularly...

Of birthday cakes and interactions of density-dependence

There are few things that we perceive as exclusively good or bad. Whether something is good or bad often depends on conditions and circumstances. Take, for example, a birthday party. Most of us like to be surrounded by many dear friends to celebrate. It’s just more fun...

Cover September

The cover for our September Issue comes from the study "Host nutritional status mediates degree of parasitoid virulence" by Fanny Maure et al. The photo shows a "Spotted lady beetle (Coleomegilla maculata) attending a newly emerged parasitoid larva on a maize plant in...

How do herbivores find the plants?

Can herbivores use sight and smell to detect preferred plants from afar? Our study shows that these senses are used by a model browser, the swamp wallaby, to find and consume eucalypt seedlings. However, the use of odour and visual cues is dependent on the context -...

Can tropical forests recover after major disturbance?

Can tropical dry forests recover their species richness and composition after major disturbance? Secondary forests recovering after previous deforestation account for a substantial proportion of the world’s remaining area of tropical forest and their importance is...

Lichen it up in the trees

To recycle or steal?

Have you ever wondered how plants could save energy by doing things more efficiently? Like other organisms, plants can develop strategies that allow them to be more efficient in acquiring and conserving nutrients. To optimize the benefits of nutrient conservation,...

Stress hormones provide a cloudy picture of environmental quality and fitness

Wildlife are facing many stressors spanning climate change, loss and alteration of habitats, and pollutants. In an effort to determine whether organisms can cope with an altered environment, many ecologists and conservation biologists have begun to turn to measures of...

July Cover

The photo on Oikos' July cover shows a group of Northern gannets (Morus bassanus) foraging near their breeding colony at Bass Rock (east coast of Scotland) and is taken by Richard Shucksmith (www.ecologicalphotography.co.uk) . This photo illustrates the study "Colony...

How does temperature influence the winter moth’s phenology?

In most species phenology, or the timing of biological events such as flowering, migration, or reproduction, is crucial for survival and fitness. Several external and internal factors such as light, temperature, endogenous clocks, food-availability and density are...

Consequences of eating infected prey

We investigate the ways in which consuming pathogen-infected prey influence some important life-history parameters of insect predators. Pathogens are used in a variety of biocontrol programs, especially to control crop pests. We focused on crop-pests due to their short...

Sometimes “less is more”… ecological networks also prove us right

The networks of plant-animal interactions represent a perfect tool to capture the complexity of ecological communities, and, simultaneously, to relate the effect of this complexity on ecosystem functioning. For example, seed dispersal, an important ecological process...

All Biology is Local

All Biology is Local One of the most interesting aspects of global climate change is that, while its extent is global, its effects at the regional scale are quite variable. Yet the vast majority of studies focused on the effects of climate change have relied on work at...
