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.

Optimising daily sampling of plant–bee interaction networks

open access: yesJournal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

First record of Micrepeira hoeferi (Araneae, Araneidae) in the state of Ceará, Brazil

open access: yesBiota Colombiana
We report the first two records of Micrepeira hoeferi Levi, 1995 from the state of Ceará, Brazil. These records are based on the collection of 19 specimens from two nearby montane, semi-deciduous tropical forests located in the municipalities of Pacoti ...

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

open access: yesJournal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

A new species of the South American genus Metachaetodus (Coleoptera: Scarabaeoidea: Hybosoridae: Hybosorinae) Una nueva especie del género sudamericano Metachaetodus (Coleoptera: Scarabaeoidea: Hybosoridae: Hybosorinae)

open access: yesRevista de la Sociedad Entomológica Argentina, 2010
A new species of the South American hybosorid genus Metachaetodus is described, M. carolineae Ocampo sp. nov. A key and diagnostic characters for all known species of the genus are presented. A map with the known distribution for the species is provided.

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 Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

open access: yesIntegrative Zoology, EarlyView.
Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.

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
