Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

The pace and shape of ant ageing
ABSTRACT Ants have been proposed as good models to study ageing and the effects of extrinsic mortality because of their long lifespans and plasticity of ageing within species. We discuss how age‐dependent extrinsic mortality might influence queen lifespan, and how the effect of age‐independent extrinsic mortality needs further study, accounting for ...

Specialist or generalist? Feeding ecology of the Malagasy poison frog Mantella aurantiaca [PDF]
We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey.

Ants do not prey upon an extrafloral‐nectar‐feeding predatory mite
The predatory mite Amblyseius herbicolus is an important natural enemy of various crop pests and occurs in agroforestry coffee systems, where it feeds on the extrafloral nectar of Inga trees. Because extrafloral nectaries are often vigorously defended by ants, we tested whether ants would attack and kill the mites near nectaries.

Tetramorium Parvioculum Sp. N. (FORMICIDAE: MYRMICINAE), A new species of the T. Simillimum group from Gibraltar [PDF]
We describe a new species of Tetramorium, which has so far only been found in Gibraltar. Tetramorium parvioculum sp. n. belongs to the simillimum-group, which is of Afrotropical origin.

The preference for energetic resources is positively associated with predatory activity in ants
We found that ants exhibit a stronger preference for foraging for carbohydrates and lipids (energetic nutrients) compared to amino acids. The increase in foraging for energetic nutrients compared to amino acids is positively correlated with foraging in larvae (insect predation). The nutrient preference between foraging for energetic nutrients and amino
