Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume

Plant Biology, EarlyView.
Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

Restoration Ecology, EarlyView.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

Elements of the Structure of Macrophyte Metacommunities in Coastal Wetlands: Relationships With Limnological and Climatic Variables

Ecological Research, Volume 41, Issue 2, March 2026.
We applied the Elements of Metacommunity Structure (EMS) framework to macrophyte communities across coastal wetlands in southern Brazil, identifying distinct distribution patterns among functional groups. Our results show that environmental and climatic factors shape these patterns differently, with emergent species forming Clementsian communities and ...

When Calves Get Vulnerable, Ocelots (Leopardus pardalis) Get Bold: A Camera Trap Record of Opportunistic Foraging in a Fragmented Landscape

Biotropica, Volume 58, Issue 2, March 2026.
We report the first confirmed record of an ocelot (Leopardus pardalis) dragging a newborn calf in a degraded forest fragment of southeastern Brazil. Using camera trap records, we reveal an opportunistic foraging event involving a vulnerable domestic prey within a highly fragmented landscape.
