Colouration in amphibians as a reflection of nutritional status : the case of tree frogs in Costa Rica [PDF]

open access: yes, 2017
Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status.

The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

open access: yes, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...

Developments in plant breeding for improved nutritional quality of soya beans I. Protein and amino acid content [PDF]

open access: yes, 2000
Soya beans, like other legumes, contain low concentrations of the nutritionally essential sulphur amino acid, methionine. Cysteine, although not an essential amino acid because it can be synthesized from methionine, also influences the nutritional ...

To respond or not to respond? Natural variation of root architectural responses to nutrient signals [PDF]

open access: yes, 2017
The amino acid glutamate (Glu) acts as a fast excitatory neurotransmitter in mammals. Its importance in plant signalling was recognized with the discovery of channel proteins similar to mammalian Glu receptors, as well as distinct changes in root-system ...

The epidemiological consequences of optimisation of the individual host immune response [PDF]

open access: yes, 2002
We present a simple unscaled, quantitative framework that addresses the optimum use of resources throughout a host's lifetime based on continuous exposure to parasites (rather than evolutionary, genetically explicit trade-offs). The principal assumptions
