How do ants affect spider populations in coffee plants?

Biotic interactions play a central role in determining species distribution and abundance. Indeed, some organisms can have particularly strong effects on the distribution of other species because they act as keystone species or ecosystem engineers whose effects cascade...

January Cover

I hope you haven't missed that Oikos from 2015 changes cover each month! Each month a photo from one of the papers in the issue will be featured on the cover. The January cover photo was taken by David W. Inouye. The paper in questions is "Phenological shifts and the...

Only few invading individuals, still dangerous?

Invasive species have negative economic and environmental consequences worldwide and, in our changing world, it has become increasingly important to understand their impacts. However, when assessing the impacts of invasive species, scientists often compare un-invaded...

Travelling around to catch more parasites?

Do migratory birds catch more parasites? This is explored in the Oikos Early View paper "Flying with diverse passengers: greater richness of parasitic nematodes in migratory birds" by Janet Koprivnikar and tommy L.F. Leung. Below is their short summary of the study:...

Stay or go for next clutch?

Moving to a new site for next brood? Good or bad? And why? These questions are answered in the Early View paper “Mechanisms and reproductive consequences of breeding dispersal in a specialist predator under temporally varying food conditions” by Julien Terraube and co-...

Now or never: adaptive phenology and biotic interactions

Timing is everything. For an interaction to take place, organisms not only have to be at the same place, they need to be there at the same time. The timing of flowering has likely been an important trait ever since the first flowers appeared on Earth ~200 million years...

Welcome new SE: Francois Massol

We are very happy to welcome Dr. Francois Massol to Oikos Editorial Board. Get to know him here: What’s your main research focus at the moment? These days, I try and focus my efforts on the evolution of dispersal and the evolutionary ecology of interaction networks...

How small rodents in the Arctic affect birds in New Zealand

The complicated predator-prey interactions are one of the most fascinating fields in ecology. They have been studied for decades, and the more we learn, the more surprising and unpredicted stories that we find. For me, finding that small rodents (lemmings) in the high...

Not easy being a seedling…

Who will eat me and how fast will I be out-competed? Questions about the future for eucalyptus seedlings in a kangaroo world. Read more in Early View paper “Associational refuge in practice: can existing vegetation facilitate woodland restoration?” by Rebecca S. Stutz...

Butterfly resilience to climate warming

How species may cope with global warming is studied in the Early View paper “Geographic mosaics of phenology, host preference, adult size and microhabitat choice predict butterfly resilience to climate warming” by Nichole L. Bennett and coworkers. Below is their...
