Effects and observation of migrating birds on a boundary-layer windprofiler in Eastern Germany
Boundary-layer windprofilers recently have become more and more a standard technique for measuring lower atmospheric wind profiles operationally. Although the availability of reasonable data is quite high, there are about 2 % of all profiles which show ...

Radar studies of bird migration [PDF]
Observations of bird migration with NASA radars were made at Wallops Island, Va. Simultaneous observations were made at a number of radar sites in the North Atlantic Ocean in an effort to discover what happened to those birds that were observed leaving ...

Avian Haemosporidian blood parasite infections at a migration hotspot in Eilat, Israel [PDF]
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 ...

A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Reviving a Legacy Citizen Science Project to Illuminate Shifts in Bird Phenology
Climate change has been of high interest to both the scientific community and the public at large since the phenomenon was first suggested. Subsequently, and with growing evidence of its impending ramifications, numerous studies have attempted to ...

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

Global analysis of threat status reveals higher extinction risk in tropical than in temperate bird sister species [PDF]
Given increasing pressures upon biodiversity, identification of species’ traits related to elevated extinction risk is useful for more efficient allocation of limited resources for nature conservation.

Pre‐oviposition development of the brown anole (Anolis sagrei)
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...
