Demography and Population Dynamics of a Small Mammal Assemblage in Chilean Semiarid Thorn-Scrub Habitat: A 30-Year Study. [PDF]

open access: yesEcol Evol
Using the longest and most comprehensive demographic database available in temperate South America, we characterize the population dynamics of an entire community of small mammals in a semiarid environment in north‐central Chile using a superpopulation CMR modeling framework.

Differential utilization of surface and arboreal water bodies by birds and mammals in a seasonally dry Neotropical forest in southern Mexico

open access: yesEcology and Evolution, Volume 13, Issue 11, November 2023., 2023
This study examined the utilization of surface and arboreal water sources by birds and mammals in a seasonally dry tropical forest in southern Mexico. Camera traps were deployed in waterholes, rock pools, and water‐filled tree holes in the Calakmul Biosphere Reserve, Mexico.

Control of Source‐To‐Sink Processes on the Dispersal, Fractionation, and Deposition of Magnetic Minerals in a Tropical Mesotidal Estuarine System

open access: yesGeochemistry, Geophysics, Geosystems, Volume 24, Issue 11, November 2023., 2023
Abstract This study aims to elucidate the control of source‐to‐sink processes on the sediment dynamics of a complex mesotidal tropical estuarine system using rock magnetic, sedimentological, mineralogical, and geochemical methods. Integration of multiproxy data of catchment rocks, riverbank and hinterland soils, and bedload sediments from various ...

Neo‐tropical felid activity patterns in relation to potential prey and intraguild competitors in the Calakmul Biosphere Reserve, Mexico

open access: yesBiotropica, Volume 55, Issue 5, Page 969-977, September 2023., 2023
There is little temporal segregation between the nocturnal activities of jaguars, pumas, and ocelots in Mexico's Calakmul Biosphere Reserve, although pumas were more active closer to dawn. Jaguars had low activity overlap with species likely to be common prey, whereas ocelots had high overlap with their potential prey.

Cenozoic Exhumation and Deformation of the Intermontane Pastos Chicos Basin in the Southern Central Andes: Implications for the Tectonic Evolution of the Andean Plateau (Puna) and the Eastern Cordillera Between 23° and 24°S, NW Argentina

open access: yesTectonics, Volume 42, Issue 2, February 2023., 2023
Abstract The Andean Plateau of north‐western Argentina (Puna) at a mean elevation of ca. 4.2 km constitutes the southern continuation of the Altiplano; it is a compressional basin‐and‐range province comprising fault‐bounded, high‐elevation mountain ranges and largely internally drained basins with often thick sedimentary and volcaniclastic fill ...

Variation in whale (Cetacea) inner ear anatomy reveals the early evolution of "specialized" high-frequency hearing sensitivity. [PDF]

open access: yesJ Anat
Our findings support sensitivity to low‐frequency sound in the archaeocete Zygorhiza kochii and an early toothed mysticete cf. Aetiocetus. Narrow‐band high‐frequency hearing was present in Oligocene odontocetes and stem delphinidans, suggesting it evolved earlier than expected and could represent an ancestral trait rather than a recent innovation ...
