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.

Talla de madurez y época de desove de la reineta (Brama australis Valenciennes, 1836) en la costa central de Chile [PDF]
Investigaciones marinas, 2003 Landings of Pacific pomfret (Brama australis) is acquiring an increasing importance to the Chilean artisanal fishery. However, lack of information regarding its basic biology, in particular, reproductive dynamics, still persists. In this work we determine the spawning season of B. australis in the central coast of Chile and the length of maturity (LM).

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.

Gayana (Concepción), 2002 Los resultados muestran un valor de heterocigosidad de 11% si se considera los 12 loci presuntivos analizados. El polimorfismo es de 25%, semejante al reportado en distintas especies de peces marinos. Por otro lado el analisis estadistico de las pruebas Fst y X2 sugieren que las poblaciones de Valparaiso y Lebu se ajustan al equilibrio de Hardy ...

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.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 1, January 2024.Abstract Soft shoreline engineering is increasingly used to combine shoreline fortification with the enhancement of biodiversity and biological production of land–water transitions. From 2016 to 2021, the large‐scale ecosystem restoration project Marker Wadden has created new multiple wetland islands from local sediments in the highly modified Lake ...
