Comparative diet of three sympatric Sceloporus in the semiarid Zapotitlan Valley, Mexico Comparación de la dieta de tres especies simpátridas de Sceloporus en el valle semiárido de Zapotitlán, México

open access: yesRevista Mexicana de Biodiversidad, 2008
Ecology, morphology, and phylogeny contribute to the organization of lizard assemblages; however, the number of lizard assemblages for which detailed knowledge of closely related sympatric species is available is limited.

Beyond Species Diversity: Functional Approaches Reveal Consistent Fauna Community Responses to Exotic Grass Invasion in Arid Lands

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
To assess whether the impacts of exotic plant invasion can be generalised across taxa, we developed a conceptual framework predicting faunal responses to grass invasion in open, arid ecosystems and tested our predictions using data on birds, reptiles and ants from sites invaded by buffel grass (Cenchrus ciliaris) and paired uninvaded sites.

Selective Harvests of Brown Bears Associated With Increasing Skull Size and Older Age Structure

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Figure 1 shows brown bear hunt areas on the Kodiak Archipelago, Alaska, USA. ABSTRACT Legal harvests of wildlife occur throughout North America, where some big game hunters preferentially target individuals with larger body parts (e.g., horn, antler, body size), a practice referred to as selective harvest.

Population dynamics of a long‐lived pitviper inferred from capture–recapture data spanning four decades

open access: yesEcosphere, Volume 17, Issue 3, March 2026.
Abstract Long‐term studies of plant and animal populations are rare, particularly for long‐lived species with slow life histories. However, such studies are necessary to understand how population dynamics are affected by variation in vital rates. We used a large capture–recapture dataset spanning four decades (1983–2019) to estimate several population ...

A new taxon of saurischian dinosaur from the Coelophysis Quarry of New Mexico, USA (Triassic: latest Norian or Rhaetian) highlights herrerasaurian diversity in the latest Triassic

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The most complete record of the earliest dinosaur lineages is from the Carnian from the higher latitudes of Pangea (e.g. present‐day Brazil, Argentina), but dinosaurian assemblages from the upper stages of the Upper Triassic are better known from the low latitudes of Pangea (present day southwestern USA).
