Magnetoreception in birds: II. Behavioural experiments concerning the cryptochrome cycle
Behavioural tests of the magnetic compass of birds and corresponding immunohistological studies on the activation of retinal cryptochrome 1a, the putative receptor molecule, showed oriented behaviour and activated Cry1a under 373 nm UV, 424 nm blue, 502 nm turquoise and 565 nm green light, although the last wavelength does not allow the first step of photoreduction of cryptochrome to the semiqu...

Cause Chlamydiosis refers to an infection with organisms of the genus Chlamydia sp., which are bacteria that live within animal cells. Chlamydia psittaci is the species generally associated with this disease in birds. The severity of the disease differs by the strain of C. psittaci and the susceptibility of different species of birds. As a result, chlamydiosis may range from an inapparent infec...
متن کاملKnocking birds
Students on a Florida campus who strayed too close to a mockingbird nest found themselves under personal attack, according to a new study. A species of songbird has been shown to identify individual people in a crowd in order to target them aggressively if they pose a threat to their nests. In the new study, by Douglas Levey and colleagues at the University of Florida, Gainsville, in the Procee...

Concern is growing about the impact of climate change on organisms but there's much uncertainty about its effects. A new European study of two bird species does not provide good news.
متن کاملDynamics of Mhc evolution in birds and crocodilians: amplification of class II genes with degenerate primers.
Genes of the major histocompatibility complex (Mhc) are the most polymorphic functional loci in mammalian populations, but little is known of Mhc variability in natural populations of nonmammalian vertebrates. To help extend such studies to birds and relatives, we present a pair of degenerate primers that amplify polymorphic segments of one chain (the beta chain) of the class II genes from the ...
