Now available on Fast Track: Oganesson: a most unusual ‘inert gas’

Posted on 18. May, 2018.

Oganesson, with the symbol Og, is the artificially prepared (i.e. ‘man-made’) elementwith atomic number 118, previously known as eka-radon or Uuo (‘ununoctium’), and recently ‘blessed’ with an official name by IUPAC3. Atoms of the element were first produced using the U400 cyclotron at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, via a heavy-ion fusion reaction utilising collision of a 4820Ca beam with a 24998Cf target.

An Open Access article: A compact reaction mechanism of methane oxidation at high pressures

Posted on 27. April, 2018.

In the past decade, there has been increasing interest in fuel propellants for in-space and launcher rocket propulsion that reduce the operational cost of launching and improve rocket operating efficiency and performance. Hydrogen provides the best performance in terms of specific impulse at a high cost for the rocket engine while kerosene provides a cost optimised option for the launch vehicle.

Now available on Fast Track: Consequences of multi-scale habitat selection on reproductive success of riverine sandbar-nesting birds in Cambodia

Posted on 26. April, 2018.

Habitat selection occurs at multiple spatial scales and affects demographic processes including reproductive success. Few studies, however, have linked multi-scale habitat selection to reproductive success. We investigated breeding habitat selection at three spatial scales (nest site, nest area and territory), and the consequences of habitat selection on reproductive success of four riverine sandbar-nesting bird species in Cambodia.

Global restriction of using antibiotic growth promoters and alternative strategies in poultry production

Posted on 24. April, 2018.

The use of antibiotics in animal and poultry feed has been a global practice since the middle of the last century. Antibiotics are used both at therapeutic and subtherapeutic levels to promote growth and feed efficiency. However, judicial use of antibiotics in food animals for growth promotion and disease prevention has been controversial for a long time due to the development of antibiotic resistant bacteria in animals and humans, resulting in treatment failure when needed.

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.

Now available on Fast Track: Migration routes and stopover sites of Upland Geese (Chloephaga picta) in South America

Posted on 17. April, 2018.

The Upland Goose (Chloephaga picta picta) is a migratory species of South America, which breeds from September to April in Patagonia (Argentina and Chile) and winters from May to September in the southern Pampas (Argentina). Despite some protection in both countries, this species is still persecuted and large numbers are killed by unregulated hunting.

Kinetic studies of the reactions between dichlorido(1,2-diaminoethane)zinc(II) and biologically relevant nucleophiles in the presence of chloride

Posted on 16. April, 2018.

The mole-ratio method was used for determining metal–ligand stoichiometry for the reaction between [ZnCl2(en)] (where en = 1,2-diaminoethane or ethylenediamine) and chloride ion at pH 7.2. The results have shown step-wise formation of 1:1 and 1:2 complexes and indicate additional coordination of chloride ions in the first coordination sphere.

Now available on Fast Track: Cryoprotective effect of glycerol concentrations on Indian Red Jungle Fowl (Gallus gallus murghi) spermatozoa

Posted on 13. April, 2018.

Semen cryopreservation protocols for wild avian species need to be optimised in order to achieve optimum post-thaw sperm quality and fertility. The present study was designed to evaluate the cryoprotective effect of different glycerol concentrations (11%, 15% and 20%) on post-thaw quality, recovery rates, absolute livability index and fertility of Indian Red Jungle Fowl (Gallus gallus murghi) semen.
