Spring arrival of birds depends on the North Atlantic Oscillation
The timing of arrival of 81 migratory species in response to the North Atlantic Oscillation (NAO) was studied at two Finnish bird observatories (1970 /99). Timing was determined for the first migrants and for the peak of migration, as well as for the early, median and late phases of migration, defined as the dates when the seasonal cumulative sum of birds reached 5%, 50% and 95%, respectively. ...

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 کاملSexual size dimorphism and timing of spring migration in birds.
Sexually selected traits are limited by selection against those traits in other fitness components, such as survival. Thus, sexual selection favouring large size in males should be balanced by higher mortality of larger males. However, evidence from red-winged blackbirds (Agelaius phoeniceus) indicates that large males survive better than small males. A survival advantage to large size could re...
متن کاملGenetic Identification of Symbiodinium in Genus Acropora off Farur Island, Persian Gulf
Coral reefs which form some of the most diverse ecosystems on Earth support many symbiotic relationships. Symbiodinium can provide up to 90% of a coral.s energy requirements. Temperature rise, turbid water and high salinity in the Persian Gulf were among the factors separating zooxanthellae from corals and result in bleaching phenomenon. Therefore, it is crucial to identify Symbiodinium of the ...
متن کاملEffect of noise stress on in-vivo fertilization capacity of male rats and subsequent off spring quality
Objective: The present experimental study was designed to investigate the elucidative effect of 50 days of noise stress on fertilization capacity of rat and subsequent offspring quality. Material and Methods: Two groups of 10 male rats were placed in two control and experimental groups for 50 days. In the experimental group, 90-120 dB sound intensity and frequency of 300-350 Hz of the device (...
