Portable X‐Ray Fluorescence in the Assessment of Zinc Along Grizzly Bear Hair

X-Ray Spectrometry, EarlyView.
ABSTRACT As a biomarker of past uptake of zinc, hair presents an interesting option since its growth can provide a stored record over time. This study investigates the distribution of zinc in hairs gathered from a series of grizzly bears (Ursus arctos horribilis).

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Remote acoustic monitoring of aquatic mammals

Remote acoustic monitoring of aquatic mammals
Underwater ultrasonic sound of finless porpoises Neophocaena phocaenoides were monitored concurrent with visual observations in the Yangtze River, China. In a total of a 774 km cruise, 588 finless porpoises were sighted by visual observation and 44, 864 ultrasonic pulses were recorded. The acoustic monitoring system could detect presence of the finless

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.
