Key message L atent environmental effects of genotype by environment interactions could be predicted from observed environmental covariates. Predictions into the wider target population of environments revealed greater insights. Abstract Wheat is grown across a diverse range of environments in Australia with contrasting environmental constraints. Targeted breeding to optimise genotypes in target environments is hindered by lar...

A physically active lifestyle benefits cellular aging, however the mechanisms linking physical activity (PA) with longevity remain unclear. PA is associated with longer telomere length (TL), while shorter TL has been associated with increased cellular aging. Some research suggests increased levels of inflammatory markers, such as C-reactive protein (CRP), are associated with telomere dysfunction. We tested the hypothesis that...

Aim More species‐rich communities are often assumed to contain more specialist species with narrower niches and smaller ranges. Stronger interspecific competition in species‐rich communities is thought to be a key mechanism explaining these patterns. Yet, the relationship between richness and specialisation has so far only been studied for a few taxa, and characterising the effects of interspecific competition on species distr...

Summary A metagenome expression library of bulk DNA extracted from the rumen content of a dairy cow was established in a phage lambda vector and activity‐based screening employed to explore the functional diversity of the microbial flora. Twenty‐two clones specifying distinct hydrolytic activities (12 esterases, nine endo‐β‐1,4‐glucanases and one cyclodextrinase) were identified in the library and characterized. Sequence analy...

Summary A comprehensive annual cycle for stocks and flows of zinc, based on data from circa 1994 and incorporating information on extraction, processing, fabrication, use, discard, recycling, and landfilling, was carried out at three discrete governmental unit levels—54 countries and 1 country group (which together comprise essentially all global anthropogenic zinc stocks and flows), nine world regions, and the planet as a who...
