When Raptors Are Away, Opossums Will Play: Woolly Opossums as Carrion Feeders in Harpy Eagle Nests

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Scavenging by New World marsupials is rarely documented. We recorded woolly opossums (Caluromys lanatus) scavenging prey remains from a Harpy eagle’s nest in central Brazil. The low overlap in activity periods between the two species may facilitate the behavior observed here.

From Hot to Cold Spots: Climate Change is Projected to Modify Diversity Patterns of Small Mammals in a Biodiversity Hotspot

open access: yesDiversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Climate change represents one of the main threats to global biodiversity, and such alterations are expected to induce shifts in distribution ranges and diversity patterns. We evaluate if protected areas and forest remnants in the Atlantic Forest in South America (AF) are projected to ensure the taxonomic diversity (TD) and phylogenetic ...

Male influence on oestrous cycles in female woolly opossum (Caluromys philander) [PDF]

open access: yesReproduction, 1991
Plasma progesterone concentrations and the occurrence of oestrous cycles were studied in isolated woolly opossums subsequently subjected to male influences during a 40-day period. Pairing (N = 48) or exposure to male urine (N = 15) resulted in all females exhibiting oestrous during the stimulation phase, providing evidence that the activation of ...

Segregação de recursos por diferentes espécies de morcegos (Mammalia: Chiroptera) na Reserva Biológica de Sooretama [PDF]

open access: yes, 2013
Em ecologia, uma das ideias mais importantes é o princípio da exclusão competitiva, ou Lei de Gause, que afirma que duas espécies competindo pelos mesmos recursos não podem coexistir de modo estável se todos os outros fatores ecológicos forem constantes.

Down to earth: therian mammals became more terrestrial towards the end of the Cretaceous

open access: yesPalaeontology, Volume 68, Issue 2, March/April 2025.
Abstract The end Cretaceous extinctions had a profound effect on mammalian diversity, especially on metatherians (marsupials and their extinct relatives). Could mammalian substrate preference have influenced differential survival patterns? The plant fossil record shows changing angiosperm leaf anatomy during the last ten million years of the Cretaceous

Latitudinal Variation in the Timing of Nest Predator Activity Is Habitat Specific

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim The goal of this work was to investigate whether the community of avian nest predators shifts from nocturnal to diurnal with changes in latitude. This hypothesis was formulated 70 years ago, under the rationale that longer day length during the bird breeding season at high latitudes increases opportunities for visual predators.
