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.

Free from the Archives - Artificial transmembrane channels for sodium and potassium

Posted on 5. June, 2014.

Transport of alkali metals, particularly sodium and potassium, across cell membranes is an essential function performed by special proteins that enable cells to regulate inter- and extracellular ion concentrations with exceptional selectivity. The importance of these channel-forming proteins has led to researchers emulating of their structural features: an ion-specific filter and conduction at rates up to 108 ions per second.

Pyrolysis of trifluoromethane over activated carbon: role of the surface oxygen groups

Posted on 12. May, 2014.

Trifluoromethane (CHF3, HFC-23) is the major byproduct during the manufacture of HCFC-22 (CHClF2) which is one of the key feedstocks for the production of various materials, such as PTFE, PVDF, refrigerants, fire extinguishing agents and foams.

Free for the next 7 days - Chemical synthetic biology

Posted on 10. May, 2014.

The new and fashionable term synthetic biology (SB) is used mostly to indicate a field that is aimed at synthesising biological structures or life forms in the laboratory which do not exist in nature; this is based on the engineering principles of standardisation, modularisation and characterisation, coupled to systematic design.

The evolutionary ecology of nest construction: insight from recent fish studies

Posted on 9. May, 2014.

Nests are built by a wide variety of animals as functional receptacles for developing eggs and offspring, and they play a critical role in the reproductive biology of many species. Traditionally, research on the ecology and evolution of nest building and construction behaviour has focused primarily on birds, and avian studies have dominated the literature. However, as researchers working on non-bird models have realised the importance of nest construction in evolutionary ecology, the number of studies published on the nesting behaviour of nonbird taxa has increased.
