Arboreal camera trapping reveals diel-vertical migrations in arboreal wildlife of the Peruvian Amazon rainforest

open access: yesEnvironmental Research: Ecology
Tropical forests harbor much of Earth’s biodiversity, with the ground to emergent canopy forming dynamic three-dimensional habitats. Arboreal and semi-arboreal species navigate the vertically heterogeneous environment, in temperature, light, predation ...

Influence of ruminal methane on digesta retention and digestive physiology in non-lactating dairy cattle [PDF]

open access: yes, 2016
Enteric methane (CH4) production is a side-effect of herbivore digestion, but it is unknown whether CH4 itself influences digestive physiology. We investigated the effect of adding CH4 to, or reducing it in, the reticulorumen (RR) in a 4 × 4 Latin ...

Sloth biology: an update on their physiological ecology, behavior and role as vectors of arthropods and arboviruses

open access: yesBrazilian Journal of Medical and Biological Research, 2001
This is a review of the research undertaken since 1971 on the behavior and physiological ecology of sloths. The animals exhibit numerous fascinating features. Sloth hair is extremely specialized for a wet tropical environment and contains symbiotic algae.

Evolutionary Signatures amongst Disease Genes Permit Novel Methods for Gene Prioritization and Construction of Informative Gene-Based Networks [PDF]

open access: yes, 2015
Genes involved in the same function tend to have similar evolutionary histories, in that their rates of evolution covary over time. This coevolutionary signature, termed Evolutionary Rate Covariation (ERC), is calculated using only gene sequences from a ...

Arboreal mammal use of canopy walkway bridges in an Amazonian forest with continuous canopy cover [PDF]

open access: yesNeotropical Biology and Conservation
The Amazon Basin is a biodiversity hotspot, with vertically stratified forests fostering complex habitats and high mammal diversity. Although mammals play a critical role in maintaining ecosystem structure, less is known about arboreal mammal activity ...

Leishmaniasis: new approaches to disease control. [PDF]

open access: yes, 2003
The leishmaniases afflict the world's poorest populations. Among the two million new cases each year in the 88 countries where the disease is endemic (fig 1), it is estimated that 80% earn less than $2 a day.

Three-dimensional kinematic analysis of the pectoral girdle during upside-down locomotion of two-toed sloths (Choloepus didactylus, Linné 1758)

open access: yesFrontiers in Zoology, 2010
Background Theria (marsupials and placental mammals) are characterized by a highly mobile pectoral girdle in which the scapula has been shown to be an important propulsive element during locomotion.
