Atlas of birds in the Province of Ancona
Rivista Italiana di Ornitologia - Research in Ornithology, 2012 In the years 2005-2006 the monitoring of breeding birds populations in the province of Ancona, on 66 quadrants of land measuring about 36 square kilometers was carried out. 126 nesting species were detected, of which 120 confirmed and 6 probable.

Magnetoreception of Directional Information in Birds Requires Nondegraded Vision [PDF]
Current Biology, 2010 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

INITIAL FLIGHT DIRECTIONS OF HOMING BIRDS
The Biological Bulletin, 1955 1. The initial flight directions of common terns and Leach's petrels were observed for as long as possible after release in unknown, inland areas. In some experiments two observers obtained cross bearings on each tern for as long as it could be seen through binoculars (maximum 12 minutes and two miles distance).This procedure is strongly recommended ...

Sensing Magnetic Directions in Birds: Radical Pair Processes Involving Cryptochrome [PDF]
Biosensors, 2014 Birds can use the geomagnetic field for compass orientation. Behavioral experiments, mostly with migrating passerines, revealed three characteristics of the avian magnetic compass: (1) it works spontaneously only in a narrow functional window around the intensity of the ambient magnetic field, but can adapt to other intensities, (2) it is an ...

Global Ecology and Conservation, 2020 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.

Evaluation of national parks on the basis of Nature 2000 areas
Environmental Protection and Natural Resources, 2017 The goal of this work is to present the valorisation of national park based on the criteria resulting from standard data forms (SDF). The analysis covered a number of areas protected under the Birds Directive and Habitats Directive with the A, B or C ...
