Basal rate of metabolism (BMR) is a physiological parameter that should be measured
under strictly defined experimental conditions. In comparative analyses among mammals …

The mechanisms underlying the high extant biodiversity in the Neotropics have been
controversial since the 19th century. Support for the influence of period-specific changes on …

Bats are incredibly diverse, both morphologically and taxonomically. Bats are the only
mammalian group to have achieved powered flight, an adaptation that is hypothesized to …

For centuries, biologists have been captivated by the vast disparity in species richness
between different groups of organisms. Variation in diversity is widely attributed to …

Dietary adaptation is a major feature of phenotypic and ecological diversification, yet the
genetic basis of dietary shifts is poorly understood. Among mammals, Neotropical leaf …

Assessing the levels of oxidative stress markers and antioxidant enzymes in the brain is
crucial in evaluating its antioxidant capacity and understanding the influence of various …

Understanding causes and consequences of ecological specialization is of major concern in
conservation. Specialist species are particularly vulnerable to human activities. If their food …

Diseases emerging from wildlife have been the source of many major human outbreaks.
Predicting key sources of these outbreaks requires an understanding of the factors that …

In large man-made reservoirs such as those resulting from hydroelectric dam construction,
bacteria transform the relatively harmless inorganic mercury naturally present in soil and the …

Introduction Evolutionary theory suggests that the ancestors of all placental animals were
nocturnal. Visual perceptive function of mammalian brain has evolved extensively, but …
