Our latest issue covers an impressive array of subjects: from metabarcoding (with associated presentation), to population genetics and population monitoring (with video explaining a microphone array system). Modelling and monitoring dispersal also features heavily with four articles, one of which is accompanied by a video for a novel telemetry system to track wild animals. Articles also include topics such as transient dynamics, a review on hormone assay, phylogenetic comparative analysis, stable isotopes (featuring our cover article), plant physiology and finally, statistical methods.
About the cover
Stable-isotope ratios measured in migrating animals have proven to be of great value in understanding migration. For example, when a dragonfly emerges from the water, the isotope signature in that water body is fixed in its wing tissues, which thus provide information about its geographic origin. In A dragonfly (δ2H) isoscape for North America: a new tool for determining natal origins of migratory aquatic emergent insects, Keith Hobson, David Soto, Dennis Paulson, Leonard Wassenaar and John Matthews compared the isotope value from dragonfly wings of known origin with spatially explicit isoscapes based on water isotopes in precipitation. The relationship was strong, confirming the value of the method to study dragonfly migration.
One of the species used in the analysis was Pachydiplax longipennis. This individual was photographed at Red Slough Wildlife Management Area, Oklahoma. Photo © Dennis Paulson.
