Sex in plants depends on their neighbours

Root competition appears to effect sex allocation in plants. Åsa Lankinen and her colleagues have studied this in the Early View paper "Allocation to pollen competitive ability versus seed production in Viola tricolor as an effect of plant size, soil nutrients and...

Effects of monoculture on plant litter decomposition

In the new early view paper "Do physical plant litter traits explain non-additivity in litter mixtures? A test of the improved microenvironmental conditions theory", Marika Makkonen and co-workers, present a new theory on decomposition rates. Here's their own summary...

Why red leaves?

At least here in southern Sweden, the autumn colours have been fantastic this year! As an evolutionary ecologist one starts wonder: why does trees differ in level of coloration? Is it only a benefit to the tree? Or are there costs associated with it as well? And why...

New pollination network model

In the new paper "Adaptive foraging allows the maintenance of biodiversity of pollination networks" Fernanda S. Valdovinos and her colleagues present a new population-dynamics model for plant-pollinator interactions: Here's Fernanda's summary of the model: One of the...

Exotic invaders are modified by natives

Alien, invasive species are an increasing threat to biodiversity. In their paper "Competitive outcomes between two exotic invaders are modified by direct and indirect effects of a native conifer", Kerry Metlen and co-workers has studied what two invasive species - a...

Battlefield study: Grasshoppers vs. wolf spiders

That predator-prey interactions can be temperature-dependent is something that Angela Laws and Anthony Joern shows in the new Early View paper in Oikos "Predator–prey interactions in a grassland food chain vary with temperature and food quality" Read their background...

How Google affects biodiversity

Is there really a connection between biodiversity and conservation and Internet? Oh, yes, read Michal Zmihorski and his colleagues new Early View paper in Oikos, " Ecological correlates of the popularity of birds and butterflies in Internet information resources"...

Relatedness and colonisation

How close to a relative should one settle? David Aguirre et al have shown that relatedness has an effect on colonization and settlement in some species, at least. Here's David's summary of the paper that is now on Early View in Oikos: "In organisms with sessile adults...

On architecture and moose populations

In the new Oikos paper (now on Early View), "Simulated responses of moose populations to browsing-induced changes in plant architecture and forage production", John Pastor and Nathan R. de Jager present a model examining how tree crown architecture affects moose...

What shapes the personality?

Oh, yes, fish have personalities as well! Matthew Edenbrow and his colleague has digged deeper into this to unravel the basis behind it. Now on early View: "Environmental and genetic effects shape the development of personality traits in the mangrove killifish...
