Declines in Freshwater Mussels and Loss of Mussel–Invertebrate Interactions in the Subtropical Waterbodies of Dhaka, Bangladesh

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 11, November 2024.
ABSTRACT Freshwater mussels are a globally threatened taxon, but little is known about population trajectories for species outside Europe and North America. To contribute to understanding of mussel conservation status outside these regions, we surveyed mussel and other invertebrate populations in waterbodies across Dhaka, Bangladesh, to assess ...

An Invasive Predator Substantially Alters Energy Flux Without Changing Food Web Functional State or Stability

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 9, September 2024.
ABSTRACT Understanding how invasive species affect the stability and function of ecosystems is critical for conservation. Here, we quantified the effect of an actively suppressed invasive species on the Yellowstone Lake ecosystem using a food web energetics approach.

Riding the wetland wave: Can ducks locate macroinvertebrate resources across the breeding season?

Ecology and Evolution, Volume 14, Issue 6, June 2024.
Nektonic macroinvertebrate density varies across wetland types and over time during the waterfowl breeding season, with basin wetlands harboring the highest density and the most stable resources. Waterfowl pairs are able to track these densities and are found in the greatest numbers in the wetlands with the highest food density during the breeding ...

Facilitation of benthic assemblages by Bluehead Chubs: Testing the stress‐gradient hypothesis in streams

Ecology of Freshwater Fish, Volume 33, Issue 2, April 2024.
Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

Facies distribution and depositional cycles in lacustrine and palustrine carbonates: The Lutetian–Aquitanian record in the Paris Basin

The Depositional Record, Volume 10, Issue 1, Page 124-158, February 2024.
In this work focussing on the Cenozoic continental carbonates of the Paris Basin, new information is brought to light on the spatialisation of continental carbonates facies thanks to correlations between coastal and palustrine environments. It presents arguments for distinguishing between marine (lagoon‐type) and continental (lake‐type) deposits based ...

The fossil record of freshwater Gastropoda – a global review

Biological Reviews, Volume 99, Issue 1, Page 177-199, February 2024.
ABSTRACT Gastropoda are an exceptionally successful group with a rich and diverse fossil record. They have conquered land and freshwater habitats multiple times independently and have dispersed across the entire globe. Since they are important constituents of fossil assemblages, they are often used for palaeoecological reconstruction, biostratigraphic ...

Biomphalaria subprona (Martens, 1899) (Gastropoda: Planorbidae)

Memorias do Instituto Oswaldo Cruz, 1996
A description is given of the shell, head-foot, pulmonary wall, reproductive system and radula of Biomphalaria subprona (Martens, 1899). A diagnosis between it and two other congeneric species under 10 mm in shell diameter occurring in Middle America ...
