Duck Tales: Spatio‐temporal dynamics of habitat use and prey relationships of a diving duck and its implication for conservation management

Conservation Science and Practice, EarlyView.
Shows the spatiotemporal predictability of wintering eiders based on monitoring data from 1993–2023 with intertidal and subtidal Marine Protected Areas (yellow and green, respectively), and a depiction of the current mismatch between eider hotspots and protection measures. Abstract Migratory animals often follow predictable spatiotemporal distributions

Beyond species diversity: Functional responses of cave arthropods to microclimatic stability and structural complexity

Ecological Entomology, EarlyView.
Species richness declined along cave microclimatic gradient, while diversity increased with habitat heterogeneity, highlighting distinct roles of abiotic conditions and structural complexity in shaping arthropod communities. Functional traits shifted along the microclimatic gradient, with larger‐bodied and more eye‐regressed arthropods dominating under

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

Ecological Entomology, EarlyView.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

Experimental Investigation on the Impact of Sand Particle Size on the Jet Pump Wall Surface Erosion

Journal of Marine Science and Engineering
Silt removal is crucial for maintaining navigable waterways in harbors. Jet pumps, without moving parts, are highly suitable for underwater operations such as channel dredging in port environments.

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Growth and Condition of Largemouth Bass (Micropterus nigricans) and Bluegill (Lepomis macrochirus) in a Minnesota, USA, Lake with Separate Dredged and Non-Dredged Basins

Limnological Review
The objective of this study was to assess the growth rates and general body condition of two common game fishes (largemouth bass Micropterus nigricans and bluegill Lepomis macrochirus) in a productive midwestern USA lake, Lake Winona, 20+ years after one

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Catastrophic shifts in the aquatic primary production revealed by a small low-flow section of tropical downstream after dredging

Brazilian Journal of Biology
Dredging is a catastrophic disturbance that directly affects key biological processes in aquatic ecosystems, especially in those small and shallow. In the tropics, metabolic responses could still be enhanced by the high temperatures and solar incidence ...
