Latin American Journal of Aquatic Research, 2023 The southern rays bream (Brama australis) is a highly migratory, epi-mesopelagic species supporting an important artisanal fishery off central-southern Chile. Despite its importance, several questions exist about this species's demography and migratory routes. The first step in understanding the migratory behavior of B.

Limnology and Oceanography: Methods, Volume 20, Issue 12, Page 789-810, December 2022., 2022 Abstract Mid‐trophic level (MTL) organisms play a key role in the sub‐Antarctic ecosystem food web, linking primary producers and tertiary consumers transferring energy across trophic levels. In this region, the relative abundance of MTLs has been monitored using single‐frequency acoustic data collected opportunistically in a time series of trawl ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 4, Page 948-963, April 2021., 2021 Abstract Invaders affect native species across multiple trophic levels, influencing the structure and stability of freshwater communities. Based on the ‘trophic position hypothesis’, invaders at the top of the food web are more harmful to native species via direct and indirect effects than trophically analogous native predators are. However, introduced

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 30, Issue 12, Page 2240-2253, December 2020., 2020 Abstract The crucian carp Carassius carassius, a cyprinid fish characteristic of small ponds, is in decline throughout most of its European range, including in England where it is currently thought to be non‐native. The present study, undertaken by the Norfolk Crucian Project, reports on reductions in pond populations of crucian carp in Norfolk ...

A New Zealand demersal fish classification using Gradient Forest models
New Zealand Journal of Marine and Freshwater Research, Volume 54, Issue 1, Page 60-85, March 2020., 2020 ABSTRACT Spatial classifications of the environment have previously been used to characterise biodiversity and to facilitate management planning at large spatial scales. Such classifications are more likely to be adopted if they can demonstrate integration of real patterns in habitats or biotic assemblages, in addition to environment.

International Review of Hydrobiology, Volume 104, Issue 5-6, Page 127-136, November 2019., 2019 Abstract The explosive global spread of Sinadonta woodiana, a large‐bodied unionid mussel of East Asian origin, potentially affects the functioning of freshwater habitats and threatens native mussels. Molecular data indicate that its invasion in Europe started with a single colonization event, followed by in situ adaptation.

Tide Management in the Elbe River and Changes in Ecosystem Services
Advances in Ecology, Volume 2016, Issue 1, 2016., 2016 Flood currents (tidal pumping) have led to the increase of transportation of sediments to the river’s upper estuary. In the tidal section of the Elbe River, more sediment is transported to the upper estuary with flood currents (tidal pumping) related to tidal asymmetry.

Interactions between stoneworts (Charales) and waterbirds
Biological Reviews, Volume 99, Issue 2, Page 390-408, April 2024.ABSTRACT Stoneworts (Charales) are green algae that represent an important food resource for many waterbird species in Europe and elsewhere. Browsing avian herbivores (e.g. swan, goose, duck and coot species) consume Charales plant vegetative parts, by head‐dipping, up‐ending or diving.
