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...

The place to study litter decomposition

This paper is based on field work mostly done in the Ohu Village. This is a village in Papua New Guinea that runs its own small rainforest conservation area of approximately 300 ha. The surrounding lands have been largely converted to food gardens or are covered by...

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...

Welcome Miguel Verdu - new SE

We are very happy to welcome Dr Miguel Verdu, Valencia, Spain to our editoral board. Below is a short interview with Miguel: What's you main research focus at the moment? I am interested in the signature that evolution leaves into ecological processes acting at species...

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...

Editor's Choice January

2017, a new year of Oikos to kick-off with two selected contributions as editor’s choices for the January issue. The first EC is the forum by Houlahan and colleagues on the priority of prediction in ecological understanding . The authors provide series of argument to...

Cover February

The February cover shows a bull moose on Isle Roylae foraging on deciduous forage in early spring. Parikh et al. show that increasingly diverse diet is associated with better nutritional status in "The influence of plant defensive chemicals, diet composition, and...

Welcome German Orizaola as new SE

We have the great pleasure to welcome Dr German Orizaola, Uppsala Univeristy to our Editorial Board. You can read more about German on his website www.gorizaola.wordpress.com and of course in myinterview with him below. What's you main research focus at the moment? My...

Plant Diversity and Decomposition

CO2 becomes plant biomass through photosynthesis and then returns to the atmosphere through respiration, including the decomposition of this biomass, forming the basis of the terrestrial carbon cycle. Research has shown that higher biodiversity of plants can increase...

Meta-analyses on sub-lethal effects of hypoxia

Findings from this meta-analysis, led by graduate students Allison Hrycik (@ahrycik) and Zoe Almeida (@almeida_zoe), suggest that the biologically relevant threshold of hypoxia for fish is 4.5 mg/l of dissolved oxygen. This is higher than the ‘typical’ definition of...

December Cover

The photo on the December cover relates to the study "Immune gene variability influences roe deer natal dispersal" by Cecile Vapné and co-workers. "The photo is taken by Olivier Villa. It shows a roe buck in a meadow. This roe buck seems particurlary healthy and in...

Editor's Choice December

We chose the forum paper of Siteur and colleagues as our first EC for the December issue. The forum focusses on how relevant deviations from steady-state may change predictions of critical transitions and resilience in current ecosystem models. Such a perspective is...

Editor's Choice November

Dear Oikos-followers. It has been a long time since we updated you on the papers that were selected as editor’s choice. In November, editor’s choices were two research papers. Jakub Szymkowiak tested the intriguing hypothesis that birds may use specific social...

Where do arctic foxes go in winter?

Tracking wild carnivores is never easy. They are fast, elusive, often nocturnal, and rarely abundant. This task can be even more daunting when a species is too small to wear a tracking device that is remotely heavy or if individuals have the ability to travel very long...

Can single species responses predict community change under global warming?

In previous experiments we grew grassland mesocosms in sunlit controlled growth chambers under different climate conditions. We investigated whether grassland species would maintain their current level of stress resistance when the global climate continues to change...

Life balance - to eat or be eaten?

Food availability and predation risk can have drastic impacts on animal behaviour and populations. The trade-off between foraging and predator avoidance is fundamental for survival of animals and will strongly modify individual body mass, since large fat reserves are...

November cover

The photo on the November cover shows "a masked flowerpiercer (Diglossa cyanea) robbing the flowers of Oreocallis grandiflora (Proteaceae) in Manu National Park, Peru. Avian nectar robbing has the potential to elicit trait-mediated indirect effects on plants by...

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...
