Allochthonous chemical cues drive predation by a top carnivore

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Identifying the mechanisms by which mobile predators detect and select prey remains a central challenge in sensory biology and functional ecology. This study provides the first direct evidence that chemical cues associated with allochthonous organic matter (e.g.

Benthic and hyporheic invertebrate community responses to seasonal flow recession in a groundwater-dominated stream [PDF]

, 2011
Natural hydrological variability in lotic ecosystems can include prolonged periods of flow recession. A reduction in discharge is accompanied by abiotic changes in benthic and hyporheic habitats, often including reductions in s habitat availability ...

Shorebird responses to fine‐scale water level fluctuations and macrofauna biomass in a newly constructed freshwater wetland

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Restoration of marine and freshwater wetlands for shorebirds is essential for the recovery of their declining populations. An ongoing approach is to restore shorebird habitats by large‐scale engineering, expecting the return of birds once suitable abiotic conditions are (re)established.

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

Restoration Ecology, Volume 34, Issue 4, May 2026.
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.

Is tagging with visual implant elastomer a reliable technique for marking earthworms? [PDF]

, 2009
Visual implant elastomer (VIE) has recently been employed to investigate different aspects of earthworm ecology. However, a number of fundamental questions relating to the detection and positioning of the tag, its persistence and potential effects on ...

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

Influência da contaminação de solo por creosoto na ocorrência de Oligochaeta em fragmentos da Mata Atlântica

Boletim do Observatório Ambiental Alberto Ribeiro Lamego, 2019
Por sua abundante ocorrência e sua sensibilidade a contaminações e variações da presença de nutrientes, as minhocas são importantes bioindicadores da qualidade do solo.
