‘Fixed direction’-responses of birds in the geomagnetic field
IN A RECENT PAPER, WE DESCRIBED THE ORIENTATION BEHAVIOR OF TWO PASSERINE MIGRANTS UNDER DIM RED LIGHT: the birds headed westward in spring as well as in autumn, displaying a 'fixed direction'-response. 'Fixed direction'-responses in other directions were observed under abnormal light regimes.

Magnetoreception of Directional Information in Birds Requires Nondegraded Vision [PDF]
The magnetic compass orientation of birds is light dependent. The respective directional information, originating in radical pair processes, is mediated by the right eye. These findings suggest possible interactions between magnetoreception and vision, in particular with the perception of contours, because the right eye has been found to be dominant in

Direct Innervation of GnRH Neurons by Encephalic Photoreceptors in Birds [PDF]
In nonmammalian vertebrates, photic cues that regulate the timing of seasonal reproductive cyclicity are detected by nonretinal, nonpineal deep brain photoreceptors. It has long been assumed that the underlying mechanism involves the transmission of photic information from the photoreceptor to a circadian system, and thence to the reproductive axis. An

Broiler chickens have been selected for their rapid growth rate as well as for high carcass yields, with particular regard to the breast, and reared in intensive systems at high stocking density ranging from 30 to 40 kg live weight/m2.

Biodiversity conservation often requires a landscape perspective. When establishing the Natura 2000 (N2k) network, the effectiveness of the sites and the influence of the surrounding landscapes for species of interest was often disregarded.
