Syntheses and structures of a class of bridged bis(amidinate)s and derivatives

Amidinates are versatile ligands used in the fields of coordination and organometallic chemistry because their steric and electronic properties can be easily modulated by varying the substituents on the C and N atoms.

Condition dependence of structural plumage coverage in Indigo Buntings

Nuptial plumage colouration is seemingly favoured by females of avian species with regards to sexual selection. This particular secondary sexual characteristic has been previously shown to be a condition-dependent signal of individual quality among passerines with pigment-based colouration (i.e. yellows and reds).

Investigation of reaction mechanisms and kinetics of the radical scavenging ability of 5-tert-butylbenzene-1,2,3-triol and 3,5-di-tert-butylbenzene-1,2-diol compounds towards OOH radical

Reactive oxygen species (ROS) is a collective term used by biologists to refer to oxygen-centred radicals, such as the superoxide (O₂⁻) and hydroxyl radical (OH•), as well as some non-radical derivatives of O₂, such as hydrogen peroxide (H₂O₂), singlet oxygen (¹O₂) and hypohalites [e.g. hypochlorous acid (HOCl)] Organic derivatives of oxygen species such as alkoxyl r...

Pollinator decline – an ecological calamity in the making?

Pollination is an ecosystem function that is fundamental to plant reproduction, agricultural production and the perpetuation of terrestrial biodiversity. An estimated 87.5% (approximately 308,000 species) of the world’s flowering plants are pollinated by insects and other animals, and more than three quarters of the major types of global food crops derive at least some benefit from animal pollination.
