Global comparison of habitat intactness models for predicting extinction risk in terrestrial mammals

open access: yesEcography, Volume 2025, Issue 11, November 2025.
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.

Dental microwear in live, wild‐trapped Alouatta palliata from Costa Rica [PDF]

open access: yesAmerican Journal of Physical Anthropology, 1991
AbstractOne problem with dental microwear analyses of museum material is that investigators can never be sure of the diets of the animals in question. An obvious solution to this problem is to work with live animals. Recent work with laboratory primates has shown that high resolution dental impressions can be obtained from live animals.

Present and Future: Using Ecological Niche Modeling to Understand the Conservation Status of Alouatta caraya (Primates, Atelidae) and Promote Its Protection

open access: yesAmerican Journal of Primatology, Volume 87, Issue 8, August 2025.
Free‐living Alouatta caraya: the male (top left) and his females (bottom left). We used ecological niche modeling to assess the species' climate suitability both now and in future projections. Between now and 2030, there is a 31% reduction in distribution.
