Urban developmental environments alter tadpole phenotypes depending on origin
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

Altica ampelophaga Guerin-Meneville, 1858 - new record of Flea Beetle for Malta (Coleoptera, Chrysomelidae) [PDF]
The Chrysomelidae is a very large family of phytophagous beetles with some 40,000 described species. The majority of adults are leaf feeders, with some species specializing on a wide variety of seeds, and fewer species are associated with pollen.

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 ...

Minimising insect mortality during grassland mowing: The potential of insect chasing devices
Insect chasing devices have a great potential to deter arthropods prior to mowing, thereby reducing mortality. The effectiveness of mechanical flushing bars is limited and depends on driving speed, vegetation structure and species composition. The blowing device is the most independent of external factors and therefore the most effective.

A new trapping concept has been proposed based on a volatile compound, allyl isothyocianate, known to be attractant to some of these insects for a long time. (l) The first question was whether this compound is effectively attractive to all flea beetle

ABSTRACT Chemical communication using pheromones is crucial for the reproductive success of many insect species, including beetles (Coleoptera). Pheromones are detected by specialised odorant receptors (ORs), called pheromone receptors (PRs), in the sensory neurons of the antennae.
