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.

Synthesis of 24(28)-methylene-1α-hydroxyvitamin D3, a novel vitamin D3 analogue

Posted on 8. May, 2014.

In healthy humans, vitamin D3 which is produced from 7-dehydrocholesterol by UV exposure on skin surface, undergoes two metabolic oxidations to afford the physiologically active form of vitamin D3 (1α, 25-dihydroxyvitamin D3, calcitriol).

Free to read: Avian Models for Research in Toxicology and Endocrine Disruption

Posted on 16. April, 2014.

In the 1960s, populations of wild birds showed dramatic declines. This, in association with environmental pollution, led to long-range interests in avian toxicology and more recently to investigating chemical pollutants that may cause endocrine disruption in avian species.

Free to read: Water or ice? – the challenge for invertebrate cold survival

Posted on 16. April, 2014.

Some insects freeze, others do not. Some insects die when frozen, others do not. This encapsulates the problem facing insects and other invertebrates living in cold environments in which there is a potential to freeze. Nature has chosen not to solve the problem in a single or simple way – a wide variety of adaptations has evolved to cope with cold stress in many different environments.

A new alkaloid from the mycelium of Inonotus obliquus

Posted on 11. April, 2014.

Inonotus obliquus, a white rot fungus that belongs to the family Hymenochaetaceae (Basidiomycetes), is mainly distributed in Europe, Asia, and North America. It has been used for the treatment of gastrointestinal cancer, cardiovascular disease and diabetes since the 16th century in Russia, Poland and the Baltic countries and has been reported to have anti-inflammatory, antioxidant, immunomodulatory and hepatoprotective effects.
