Now available on Fast Track: Egg size and shape variation in Rufous Bush Chats (Cercotrichas galactotes) breeding in date palm plantations: hatching success increases with egg elongation

Posted on 23. April, 2018.

In oviparous taxa such as birds, clutch characteristics (e.g. egg size, egg mass and the number of eggs) can be considered as energetic investment in reproduction. In this paper, we study variation in the principal component indices of egg size and shape in Rufous Bush Chats (Cercotrichas galactotes) breeding in date palm plantations in the Al Amri Oasis, north Algeria, in 2008–2009 and 2011–2013.

New species of seabird discovered in Hawaiian Islands

Posted on 13. September, 2011.

For the first time in decades, researchers have found a new bird species in the United States. Based on a specimen collected in 1963 on Midway Atoll, Northwestern Hawaiian Islands, biologists have described a new species of seabird, Bryan’s Shearwater (Puffinus bryani), according to differences in measurements and physical appearance compared to other species of shearwaters. Scientists at the Smithsonian Conservation Biology Institute analysed the specimen’s DNA to confirm that it is an entirely new species. Their findings have been published online in The Condor.

Wildfires and climate change beneficial to some desert birds

Posted on 13. September, 2011.

Some bird species in the US desert southwest are less affected, and even positively influenced, by widespread fire through their habitat. Baylor University researchers say that fire actually helps some bird species because of the habitat that is formed after a fire is positive for the birds' prey needs. The study is published in the June 2011 issue of Conservation Biology.

The quick bird catches his mate

Posted on 13. September, 2011.

While the early bird might catch the worm, it's the quick bird that lands the ladies, according to new research into the running performance of an Arctic cousin of the grouse. The study was published in the August 17, 2011, issue of Proceedings of the Royal Society B.

The Promiscuous T-cell

Posted on 8. September, 2011.

T-cells are a vital type of white blood cell that scan for cellular abnormalities and infections. They recognise disease-associated antigens via a surface receptor called the T-cell antigen receptor (TCR). If there were a specific TCR for every single antigen, no mammal could possibly contain all the T-cells it needs. This suggests that T-cell recognition must be highly degenerate. Yet highly promiscuous TCRs would appear to be equally impossible: they are bound to recognise self as well as non-self antigens.  In the next issue of Science Progress, mathematical analysis helps to resolve the paradox of the promiscuous TCR.
