A new species of Temnocephala (Platyhelminthes, Temnocephalida) commensal of Pomella megastoma (Mollusca, Ampullariidae) from Misiones, Argentina Una especie nueva de Temnocephala (Platyhelminthes, Temnocephalida) comensal de Pomella megastoma (Mollusca, Ampullariidae) de Misiones, Argentina

open access: yesRevista Mexicana de Biodiversidad, 2008
Temnocephala lamothei n. sp., a commensal of Pomella megastoma (Sowerby, 1825), is described herein from specimens collected at Arroyo Yabotí-Miní (Misiones province, Argentina). Juveniles and adults were removed from the mantle cavity by host relaxation.

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

open access: yesJournal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Cold storage effects on immature calliphoridae: Survival limits and forensic consequences for PMI estimation

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract This study investigated the effects of continuous refrigeration (4°C ± 2°C and 50% ± 5% RH) on the development and survival of immature stages (eggs, first, second, and third instar larvae, and pupae) of four forensically important blowfly species (Chrysomya megacephala, Chrysomya putoria, Hemilucilia segmentaria, and Lucilia cuprina) compared

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it
