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.

Does the threat of European Pine Marten (Martes martes) predation influence the height of nests built by Blue Tits (Cyanistes caeruleus) and Great Tits (Parus major)?

Posted on 19. August, 2014.

Nesting in tree cavities evolved and was lost repeatedly in different groups of passerines, resulting in specific patterns between and within avian families.  In Paridae, nesting is almost exclusively restricted to holes in trees.

Free for 24 hour only - Feather-damaging behaviour in companion parrots

Posted on 18. August, 2014.

Parrots from over 200 species are maintained in zoos, breeding facilities, private homes, etc. In all captive settings, parrots can develop feather-damaging behaviour, in which birds repetitively chew or pluck out their feathers.  Believed to be rare or absent in wild parrots , this behaviour is of concern for many reasons.

Mechanism of the water-catalysed addition between melamine and formaldehyde: a theoretical investigation

Posted on 18. August, 2014.

The nucleophilic addition reactions of carbonyl compounds with water and amines are of fundamental importance in organic chemistry. The reaction between water and formaldehyde is a simple and typical example of hydration of carbonyl compounds. Theoretical studies have been carried out on this reaction aiming to find those details that cannot be observed by experimental methods.

Fractionation, mobility and multivariate statistical evaluation of metals in marine sediments of Cape Town Harbour, South Africa.

Posted on 15. August, 2014.

In this study, the distribution of possible chemical forms of Al, Si, Sn, Pb, Zn, Fe, Hg, Cd and Cu in marine sediments of Cape Town harbour was investigated using a modified Tessier’s sequential extraction procedure and ICP-MS and ICP-AES for heavy metals determination.

Synthesis and anticholinesterase inhibitory activity of Mannich base derivatives of flavonoids

Posted on 14. August, 2014.

Flavonoids are phenolic secondary metabolites that are widely distributed throughout the plant kingdom. Chalcones which are flavonoids precursors, are open-chain flavonoids in which the two aromatic rings are joined by a three carbon α, β‑unsaturated carbonyl system. They have been identified as antitumour agents, antiinflammatory, antivirus agents, antioxidants and free radical scavengers.

Cross-species utility of 22 microsatellite markers in the Melodious Warbler (Hippolais polyglotta)

Posted on 11. August, 2014.

The Melodious Warbler (Hippolais polyglotta) and the Icterine Warbler (H. icterina) are small, long distance migrating passerines breeding in open to semi-open scrublands or open woodland in the Western Palaearctic.

Free from the archives: The origin of life II: How did it begin?

Posted on 9. August, 2014.

The problem of how a mixture of chemicals can spontaneously transform themselves into even a simple living organism remains one of the great outstanding challenges to science. Various primordial soup theories have been proposed in which chemical self-organization brings about the required level of complexity.
