Resource selection is a dynamic behavioural process by which individuals choose resource units (e.g., pixels or points on a landscape) disproportionate to their availability in order to maximize fitness. Because it influences ...

Allantoin and allantoate, ureides formed during the catabolism of purines, accumulate in plant tissue in response to drought and other abiotic stresses. Allantoin, allantoate, and a precursor molecule, uric acid, have been ...

Personality describes the consistent, individual differences in the behaviour we observe among human and non-human models alike. One of the components of human and animal personality which has sparked interest, is the ...

Clubroot, caused by the protist Plasmodiophora brassicae Woronin, is one of the most serious diseases to affect members of the plant family Brassicaceae. This biotrophic soil-borne pathogen is an emerging threat to canola ...

A full understanding of population dynamics requires knowledge about the relative contributions of both adult survival and recruitment to population growth rate. Avian life cycles consist of a number of reproductive stages ...

Neotropical migrant songbirds have experienced severe and ongoing population declines. The lack of knowledge about migration outside North America inspired me to study the ecology of migration of a group of 11 species to ...

The peritrophic matrix (PM) lines the insect midgut and is composed of chitin and protein. It is required for organization of digestion and for protection of epithelial cells from mechanical damage, pathogens, and toxins. ...

The Arabidopsis TGA family of basic leucine zipper transcription factors regulate the expression of pathogenesis-related genes and are required for resistance to disease. Members of the family possess diverse properties ...

The 80 S cytoplasmic ribosome is the largest of three populations of ribosomes responsible for protein synthesis in plants. It is comprised of two RNA/protein subunits of unequal size: the small (40 S) subunit selects ...

Iron is an essential component of various proteins and pigments for both plants and pathogenic fungi. However, redox cycling between the ferric and ferrous forms of iron can also catalyse the production of dangerous free ...
