Effects and observation of migrating birds on a boundary-layer windprofiler in Eastern Germany
Meteorologische Zeitschrift, 1998 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 ...

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 ...

The Anatomical Record, EarlyView.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Reviving a Legacy Citizen Science Project to Illuminate Shifts in Bird Phenology
International Journal of Zoology, 2012 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 ...

Methods of quantitative and qualitative analysis of bird migration with a tracking radar [PDF]
Methods of analyzing bird migration by using tracking radar are discussed. The procedure for assessing the rate of bird passage is described. Three topics are presented concerning the grouping of nocturnal migrants, the velocity of migratory flight, and ...

Modeling highly pathogenic avian influenza transmission in wild birds and poultry in West Bengal, India. [PDF]
, 2013 Wild birds are suspected to have played a role in highly pathogenic avian influenza (HPAI) H5N1 outbreaks in West Bengal. Cluster analysis showed that H5N1 was introduced in West Bengal at least 3 times between 2008 and 2010.

The Anatomical Record, EarlyView.Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...
