The difference between rapid morphological evolutionary changes observed in populations and the long periods of stasis detected in the fossil record has raised a decade-long debate about the exact role played by intraspecific mechanisms at the interspecific level. Although they represent different scales of the same evolutionary process, micro- and macroevolution are rarely studied together and...

This is an especially interesting article that tries to identify how many variables are defining the oscillatory variation in the hare population. A logical assumption is that hare population, predator population and hare food (e.g. grass) amount are related, but which relation is responsible for the oscillation (periodicity) in the hare population. In order to determine this, the authors perfo...

Three video-formatted experiments investigated the categorization of 'above' and 'below' spatial relations in baboons (Papio papio). Using an identity matching-to-sample task, six baboons correctly matched line-dot stimuli based on the 'above' or 'below' location of the dot relative to the line (Experiment 1). Positive transfer of performance was then observed when the line-dot distance depicte...

Understanding functional traits that capture species response to overgrazing can help optimize ecosystem functioning. However, most studies have ignored the effects of life-form on above- and below-ground overgrazing. Here, we determined whether respond similarly overgrazing; does vary between annual vs. perennial life-forms. We compared common grassland fenced overgrazed meadows at four elevat...

Climate strongly influences ecological patterns and processes at scales ranging from local to global. Studies of responses climate usually rely on data derived weather stations, where temperature humidity may differ substantially that in the microenvironments which organisms reside. To help remedy this, we present a model leverages first principles physics predict microclimate above, within, be...
