Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

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.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

NEW INFORMATION ON THE COURTSHIP FEEDING BEHAVIOR OF COTINGAS OF THE GENUS CARPORNIS FROM BRAZIL

, 2023
Birds have varied pre-reproduction behaviors such as courtship feeding behavior, which is the delivery of a nuptial gift to the female by the male. The family Cotingidae comprises Neotropical birds that perform some pre-reproduction behaviors, but the ...

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

Journal of Animal Ecology, EarlyView.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Redescription and validation of Bothriechis supraciliaris (Serpentes: Viperidae)

Revista de Biología Tropical, 1998
The populations of pit vipers from South West CostaRica, have traditionally been identified as Bothriechis schlegelii(Berthold). However, in 1954 E. H. Taylor described one specimen fromthe area as a new subspecies, B.
