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...

Editor's Choice and Editorial January

This month, Dries has asked me to write the blog post for Oikos and elaborate on the editorial we wrote for the January issue of Oikos. But first, the editor’s choice of papers for this month. Mokany et al. argue that there is insufficient integration in models between...

How can so similiar species co-exist?

Some ecosystems contain assemblages of species that can be surprisingly similar in their morphology, feeding niche and ecological function, but whose diversity can facilitate the persistence of the entire ecosystems (Duffy 2006). For example, a high diversity of...

Finding the nectar robbers....

Robbers, larcenists, illegitimate visitors, parasites, exploiters… all these terms are used for animals which sometimes display a particular behaviour: they open and use a hole in the flowers to get to the nectar within. Far from being a rare event, nectar robbing is a...

December Cover!

The cover for Oikos December Issue shows "A male southwestern fence lizard (Sceloporus cowlesi) carrying a radio-transmitter displays to rivals at White Sands National Monument, New Mexico, USA". Photo by H. Streby Link to the paper: Evidence for ecological release...

Biodiversity beyond species

When people think about nature, they usually think in terms of species -- whether it be an oak tree, a red squirrel, or a sunflower. Sometimes, ecological studies fall into the same trap and categorize organisms by species when there's a lot more variation going on at...

Selection, habitat preference and the evolution of sexual size dimorphism in arvicoline voles

In mammals, the male generally is the larger sex. For example, a mature male of southern elephant seal weights 3,200 Kg on average, whereas the females in his harem typically weigh five times less. However, females do still outweigh males in some species. For example,...

Does fish size affect trophic cascades?

Understanding the ecological consequences of human activities has become a central issue in ecology. A large number of studies have shown that anthropogenic biodiversity loss is not random, but is biased against large vertebrate consumers at the top of trophic networks...

Editor's choice December

EC papers for our last issue of 2015 are Mrowicki et al’s contribution on the context dependency of species loss effects in a marine system and Maino and Kearney’s synthesis on the variation in metabolic scaling in insects according to body size. The impact of species...

Welcome Silke Langenheder - new SE

We're very happy and proud to welcome Dr Silke Langenheder, Uppsala University to our editorial board. Get to know Silke in the interview below. What's your main research focus at the moment? I am a microbial community ecologist and the overall aim with my research is...

The power-law nature of individual body size variation

The ubiquitous Taylor’s law (TL) scaling between the mean and the variance of species population density was discovered more than half a century ago. The mechanistic basis of TL has been the focal point of research, and little attention was paid to its application...

What's the colour of environmental noise?

Understanding the environmental conditions that a species can tolerate is a growing concern in ecology and evolutionary biology. Research is beginning to reveal that the environmental factors that actually challenge organisms in nature (e.g., temperature, precipitation...

Welcome new SE - Yngvild Vindenes

We're very happy to welcome Dr Yngvild Vindenes, Oslo, Norway, to our Editorial Board. Get to know her in the mini-interview below! And visit her webpage here . What's you main research focus at the moment? I use demographic approaches (such as matrix models and...

November Cover

The cover on the November Issue is an illustration made by K. Curtis-Hill, asociated with the paper "Recognizing cross-ecosystem responses to changing temperatures: soil warming impacts pelagic food webs" by Samuel B. Fey et al. "Lakes respond to direct and cross-...

Spatial effects in mycorrhizal communities

The symbiosis between plants and arbuscular mycorrhizal fungi (AMF) is a crucial interaction that mediates nutrient cycling in terrestrial ecosystems. It is hypothesized that this symbiosis was essential for the evolutionary radiation of terrestrial plants...

Digging into the data – what can we learn from decades of monitoring?

Our recent article in Oikos seeks to understand biological interactions and long-term trends in northern Baltic Sea phytoplankton communities. At the heart of this article, however, is long-term monitoring data collected by Stockholm University as part of the Swedish...

Timing is crucial for consequences of migratory connectivity

Migratory animals typically visit several places throughout their journeys. It is widely acknowledged that ‘migratory connectivity’ - the geographic linking of individuals and populations between one life cycle stage and another - has consequences for migrant fitness...
