Jaguar Density at the Northeastern Limit of Its Distribution in Mexico

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study presents the first estimate of jaguar density in northeastern Mexico using a spatial capture–recapture model with random thinning, which incorporates both identified and unidentified camera trap detections. Conducted over 91 days with 104 cameras, the model yielded a density of 1.29 individuals per 100 km2 in the El Cielo–Sierra de Tamalave ...

Negative attitudes of an indigenous community are associated with lethal control of rodents in a temperate forest of Mexico

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
The essential ecological roles of rodents are often overlooked, as they can decimate crops and spread diseases. We aimed to unpack the knowledge, attitudes and control practices of farmers and foresters towards rodents from an indigenous community in Nuevo San Juan, Mexico.

Using Noninvasive Magnetic Resonance Imaging for the Visualization of Embryos of the Viviparous Goodeidae (Pisces; Cyprinodontiformes) at Different Developmental Stages

open access: yesInternational Journal of Zoology, Volume 2026, Issue 1, 2026.
The study of prenatal interactions of embryonic viviparous Cyprinodontidae (Pisces) can illuminate the evolution of this reproductive mode. Yet the small size, relative scarcity, and conservation status severely limit this potential. Magnetic resonance imaging (MRI) can solve or palliate these limitations.

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

open access: yesAntipode, Volume 57, Issue 6, Page 2213-2240, November 2025.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Rethinking the Spanish plume: An airstream analysis challenges the canonical conceptual model

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 773, October 2025 Part B.
Three‐dimensional airstream model showing the history of air‐parcel trajectories arriving at Nottingham on 1200 UTC 1 July 2015 at 950, 850, 650 and 250 hPa, respectively. Four different airstreams are illustrated, none of which can be easily called the Spanish‐plume airstream.

Shortening, Exhumation, and “Flip” in Tectonic Vergence of the Cordillera Central and Southern Dominican Republic

open access: yesTectonics, Volume 44, Issue 10, October 2025.
Abstract In a subduction zone, variability in the buoyancy and structure of the downgoing plate impacts deformation patterns in the overriding plate. Thick and buoyant lithosphere or smaller‐scale indentors entering the trench can lead to significant relief development and exhumation. To investigate such processes, we target the Cenozoic reorganization

Bryozoan internal moulds from the La Meseta Formation (Eocene) of Seymour Island, Antarctic Peninsula

open access: yesPolish Polar Research, 2015
AbstractThe loose, small zooecia of the cheilostome bryozoans have been discovered in the lowermost part of the LaMeseta Formation on Seymour (Marambio) Island. They systemati− cally include the representatives of Beanidae Canu et Bassler, Catenicellidae Busk, Savi− gnyellidae Levinsen, and Calwelliidae MacGillivray.
