Infomap Bioregions: Interactive mapping of biogeographical regions from species distributions [PDF]
Biogeographical regions (bioregions) reveal how different sets of species are spatially grouped and therefore are important units for conservation, historical biogeography, ecology and evolution. Several methods have been developed to identify bioregions

Euarchontan opsin variation brings new focus to primate origins [PDF]
Debate on the adaptive origins of primates has long focused on the functional ecology of the primate visual system. For example, it is hypothesized that variable expression of short- (SWS1) and middle-to-long-wavelength sensitive (M/LWS) opsins, which ...

The Influence of Moonlight on Activity of Woolly Opossums (Caluromys philander) [PDF]
Activity of four radiocollared woolly opossums ( Caluromys philander ) showed an inverse relationship between moonlight and both level and duration of the activity period. However, between new moon and half-moon, both measures of activity in females remained low on average, whereas they decreased sharply in males. The influence of moonlight on activity,

Abstract The binturong Arctictis binturong and yellow‐throated marten Martes flavigula are widely distributed through much of Southeast Asia, yet their natural history remains poorly understood. We radio collared and tracked five male binturongs, and five yellow‐throated martens (four males and one female) for 4–23 months in Phu Khieo Wildlife ...

Morphometrics of genus Caluromys (Didelphimorphia : Didelphidae) in northern South America [PDF]
We reviewed the morphometric relationships between different forms of the woolly opossum, genus Caluromys, in northern South America by means of univariate and multivariate analyses of skull characters.

In this study, we test the hypothesis that body size is a key factor in determining dominance relationships during agonistic encounters between captive males Caluromys philander, and male-male competition was experimentally tested. Physiological and behavioural parameters were investigated during 18 experimental trials including two males alone (6 ...

ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

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

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 ...
