Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, Volume 108, Issue 6, Page 1778-1787, June 2026.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Applying the Ecological Trap Concept to Cetaceans

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Wild animals may select poor‐quality habitats due to mismatches between perceived and actual habitat quality, creating ecological traps. Although well explored in terrestrial systems, this concept remains underutilized for marine species.

Habitat Preferences and Short‐Term Dynamics of Alien Fishes Revealed by Environmental DNA in River Floodplains

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Based on eDNA metabarcoding, the study revealed habitat‐use patterns and the temporal dynamics of non‐native fish species in two Danubian floodplains. Hydrological connectivity played a major role in shaping alien fish community assembly. ABSTRACT Floodplains are among the most diverse freshwater ecosystems, yet they are increasingly threatened by ...

Habitat use and diel activity of insectivorous bats across land‐cover types on an Afrotropical oceanic island

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
Using acoustic surveys, we investigated habitat use and diel activity patterns of insectivorous bats across the main land‐use types of the endemic‐rich Príncipe Island, in Central West Africa. We sampled bat activity at 48 sites spanning old‐growth forests, secondary regrowth forests, shaded cocoa plantations, and horticultural areas.

Grassland management, soil biota and ecosystem services in sandy soils [PDF]

, 2010
Recent legislative restrictions on the use of fertilizers and irrigation, and a quest for sustainable farming systems have drawn renewed attention to the functioning of the soil and the ecosystem services it provides. Soil biota play an important role in

Factors Influencing Species Distribution Model Performance in Tropical Reef Fishes

Diversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim Reliable biodiversity assessments using species distribution models (SDMs) are essential for effective conservation and management. Understanding factors influencing SDM performance is crucial for improving model reliability, yet such links remain underexplored in marine systems.
