Habitat architecture influencing microcrustaceans composition: a case study on freshwater Cladocera (Crustacea Branchiopoda)

Brazilian Journal of Biology
Environmental complexity is considered a key factor for diversity enhancement in aquatic ecosystems. Macrophyte stands are a major contributor for this complexity due to their differential architectures.

The dissipation and risk alleviation mechanism of PAHs and nitrogen in constructed wetlands: The role of submerged macrophytes and their biofilms-leaves

Environment International, 2019
The role of submerged macrophytes (Vallisneria natans, Hydrilla verticillata and artificial plant) and their biofilms-leaves for the dissipation and risk alleviation mechanism of PAHs (phenanthrene and pyrene) and nitrogen in constructed wetland systems ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, Volume 42, Issue 7, Page 1474-1499, September 2026.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Mega Mounders: Burrowing Talitrids (Megalorchestia spp.) Excavate Large Quantities of Sand on California Beaches

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract High densities of burrowing talitrid amphipods inhabit beaches around the world. This includes California, where densities of more than 1,000 individuals m−2 are regularly recorded. Here, we provide evidence of Megalorchestia spp. excavating up to 10.38 kg dry sand m−2 d−1 on a beach in southern California, one of the highest mounding rates ...

North Atlantic Ocean–Atmosphere Dynamics Controlled the Hydroclimate in Western Iberia During the Holocene

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Hydroclimate variability in western Iberia during the Holocene remains insufficiently resolved despite the high sensitivity of this region to the North Atlantic atmosphere and ocean dynamics. Here, we present the first source‐resolved reconstruction of centennial‐ to millennial‐scale moisture variability over the last 11,000 years using ...

Trophic relationships between primary producers and associated fauna in a pristine Cerrado pond

Journal of Limnology, 2019
Ponds arising from groundwater in Cerrado of Central Brazil are oligotrophic but highly biodiverse environments. In this study, we used stable isotope ratios to test if there are variations in carbon and nitrogen acquisition by different primary food ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, Volume 95, Issue 9, Page 1616-1628, September 2026.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Status of Polar Blue Carbon: Toward Recognition and Integration in Marine Policy

Global Change Biology, Volume 32, Issue 9, September 2026.
Carbon‐rich habitats in polar regions are globally important, as uptake of CO2 by marine systems is shifting toward the poles. Changing conditions are exposing these regions to anthropogenic exploitation. Timely policy intervention can protect these habitats to prevent further emissions and further integration of polar blue carbon in management ...

Restoration and rehabilitation of floodplain wetlands: a systematic, global review of restoration options and their outcomes

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Floodplain wetlands are vitally important, highly productive, and biodiverse ecosystems. Species dependent on them are facing a range of threats including water extraction, habitat degradation, invasive species, and shifting climates.

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.
