Ecology and Evolution, 2020 The consequences of bird mortality caused by collisions with wind turbines are increasingly receiving attention. So‐called acceptable mortality limits of populations, that is, those that assume that 1%–5% of additional mortality and the potential ...

, 2016 The movements of birds are among their most captivating traits. The regular seasonal movements of avian migrants are remarkably diverse: phalaropes (Phalaropus species) from the high Arctic spend their non‐breeding season in upwelling areas on open tropical seas; Northern Wheatears (Oenanthe oenanthe) traverse most of the northern hemisphere in their ...

The relative importance and biological significance of non-stop and intermittent flight strategies in bird migrants crossing the Sahara [PDF]
, 2007 IX Summary The aim of this thesis was to investigate the flight and resting strategies of birds crossing the Sahara on migration. In order to overcome the severe limitations of ground observations, we chose radar to obtain continuous data of the temporal

Oikos, EarlyView.Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

The global ecology of bird migration: patterns and processes
Frontiers of Biogeography, 2016 Nearly 20% of bird species are migratory, their seasonal movements causing a redistribution of bird diversity that radically changes avian community composition worldwide.

Cytokines of Birds: Conserved Functions [PDF]
, 2001 Targeted disruptions of the mouse genes for cytokines, cytokine receptors, or components of cytokine signaling cascades convincingly revealed the important roles of these molecules in immunologic processes. Cytokines are used at present as drugs to fight

Digital surveillance of animals and nature recovery
People and Nature, EarlyView.Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

, 2019 Migratory connectivity describes linkages between breeding and non-breeding areas. An ongoing challenge is tracking avian species between breeding and non-breeding areas and hence estimating migratory connectivity and seasonal survival.

Micro-magnetic resonance imaging study of live quail embryos during embryonic development [PDF]
, 2011 Eggs containing live Japanese quail embryos were imaged using micro-magnetic resonance imaging (μMRI) at 24-h intervals from Day 0 to 8, the period during which the main body axis is being laid down and organogenesis is taking place.

People and Nature, EarlyView.Abstract High nature value (HNV) pastoral systems, that is those maintained by herding, transhumance and extensive grazing practices, are recognised as cornerstones of European biodiversity, cultural heritage and ecosystem service provision. Yet these systems are currently under significant pressure from a range of economic, social and environmental ...
