Global comparison of habitat intactness models for predicting extinction risk in terrestrial mammals
The effects of habitat condition on biodiversity have primarily been investigated using discrete (patch‐matrix) habitat models, which consider habitat fragments as islands embedded in an inhospitable matrix. Recently, continuum habitat models, which focus on ecological gradients without defining habitat or matrix, have emerged.

An Analysis of Primate Behavioral Responses to Environmental Change: An Anthropological and Neurobiological Approach [PDF]
This thesis explores the relationship between stress, measured by glucocorticoid levels, and parasites in primate taxa to evaluate physiological and behavioral responses to humaninduced and environmental change.

Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

Methodological considerations in the analysis of fecal glucocorticoid metabolites in tufted capuchins (Cebus apella) [PDF]
Analysis of fecal glucocorticoid (GC) metabolites has recently become the standard method to monitor adrenocortical activity in primates noninvasively. However, given variation in the production, metabolism, and excretion of GCs across species and even ...

Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance
ABSTRACT The external appearance of the human eye has been prominently linked to the evolution of complex sociocognitive functions in our species. The cooperative eye hypothesis (CEH) proposes that human eyeballs, with their weakly expressed conjunctival and scleral pigmentation, are uniquely conspicuous and evolved under selective pressures to behave ...

Trade and ethnozoological use of African lorisiformes in the last 20 years [PDF]
Trade in primates is considered a major impediment to primate conservation globally. The bushmeat trade in West and Central Africa is considered largely unsustainable and represents one of the main threats to biodiversity.
