Biodiversity in mountain soils above the treeline
Biological Reviews, EarlyView.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 ...

Further records of ants (Hymenoptera: Formicidae) from Iran
, 2018 Wide ranging surveys of the ant fauna of Iran have enabled us to add a further 30 named species to the country list. A review of almost all the published literature and of photographs of unidentified specimens within the public domain gives a grand total

The pace and shape of ant ageing
Biological Reviews, EarlyView.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 ...

Effect of trail bifurcation asymmetry and pheromone presence or absence on trail choice by Lasius niger ants [PDF]
, 2014 During foraging, ant workers are known to make use of multiple information sources, such as private information (personal memory) and social information (trail pheromones).

Ants do not prey upon an extrafloral‐nectar‐feeding predatory mite
Ecological Entomology, EarlyView.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.
