Multi‐Scale Habitat Selection of Greater Caribbean Manatees in Sian Ka'an Biosphere Reserve, Mexico

Marine Mammal Science, EarlyView.
ABSTRACT Habitat selection describes population distribution as a function of environmental features. It is a fundamental process with primordial ecological and evolutionary implications. To accurately describe habitat selection, it is important to identify temporal and spatial scales perceived by the population and use these scales when modeling ...

Xylem Pit Anatomy and Minimum Leaf Conductance Drive Drought Mortality in Pinus pinaster

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought‐triggered forest die‐off events are commonly attributed to hydraulic failure, carbon starvation, or a combination of the two. Nevertheless, the anatomical and physiological traits that make trees vulnerable to drought in the field are often unknown, hindering predictive efforts.
