An empirical analysis of the cost of rearing dairy heifers from birth to first calving and the time taken to repay these costs.
Rearing quality dairy heifers is essential to maintain herds by replacing culled cows. Information on the key factors influencing the cost of rearing under different management systems is, however, limited and many farmers ...
Effects of latitude and depth on the beta diversity of New Zealand fish communities.
Marine ecosystems are difficult to sample quantitatively at increasing depth. Hence, few studies attempt to measure patterns of beta diversity for ecological communities in the deep sea. Here we (i) present and quantify ...
Environmental characteristics drive variation in Amazonian understorey bird assemblages.
Tropical bird assemblages display patterns of high alpha and beta diversity and, as tropical birds exhibit strong habitat specificity, their spatial distributions are generally assumed to be driven primarily by environmental ...
