Avian Haemosporidian blood parasite infections at a migration hotspot in Eilat, Israel [PDF]
, 2016 Haemosporidian blood parasites are frequent amongst passerines. Though they often do not cause detectable consequences to host health, however, their presence or absence and also their prevalence across host populations may potentially carry ...

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures
Ibis, EarlyView.Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Islands contribute disproportionately high amounts of evolutionary diversity in passerine birds [PDF]
, 2015 Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major ...

Ibis, EarlyView.Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

Low breeding propensity in a declining Arctic‐breeding swan revealed by telemetry data
Ibis, EarlyView.Many migratory bird populations are declining in the face of habitat degradation and climate change, making it important to identify which stages of their annual cycle are most affected in order to guide conservation measures. The Bewick's Swan Cygnus columbianus bewickii, an Arctic‐breeding waterfowl species, has suffered a dramatic population decline

A protracted phenology: Post‐diapause larval development of a threatened butterfly
Insect Conservation and Diversity, EarlyView.Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.
