Managing for resilience with ecological structure: Portfolio effects in the Laurentian Great Lakes

open access: yesFrontiers in Ecology and the Environment, Volume 24, Issue 6, August 2026.
Combined effects of global change, including land conversion, biological invasions, and overexploitation, have degraded the resilience of ecosystems and the services they provide. Here, we identify key ecological structures and processes that can be targeted by management to improve resilience at scales ranging from single species to entire landscapes.

WDS-YOLO: A Marine Benthos Detection Model Fusing Wavelet Convolution and Deformable Attention

open access: yesApplied Sciences
Accurate marine benthos detection is a technical prerequisite for underwater robots to achieve automated fishing. Considering the challenges of poor underwater imaging conditions during the actual fishing process, where small objects are easily occluded ...

Secondary production (zooplankton and benthos)

open access: yes, 1983
In order to understand the dynamics of an ecosystem, it is necessary to determine the contribution of the different groups to total biomass as well as to evaluate their turnover rates and the amount of organic matter that each produces per unit time.

Strong spatial partitioning of mesozooplankton in a dynamic frontal zone shapes trophic transfer efficiency

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Frontal zones are often areas of increased biological productivity and have hydrographic gradients on short spatial scales. The small scale of gradients poses a challenge in identifying differences in zooplankton community structure and trophic transfer efficiency through the pelagic food web.

Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...

Influence of environmental factors on the dynamics of macrobenthic crustaceans on soft-bottoms of the Ebro Delta continental shelf (northwestern Mediterranean)

open access: yesScientia Marina, 2011
Short-term temporal variability in infaunal crustacean communities was evaluated against environmental variability. The area of study was located at two stations at 45 and 60 m depth under the influence of the Ebro River.

Limited connectivity of zooplankton communities across the Labrador Front: role of physical oceanography, insights from individual motility

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Near the western margin of the highly productive Labrador Sea, the Labrador Current creates a large and steep oceanographic front between the Arctic‐origin shelf waters and the Atlantic offshore waters (i.e. the Labrador Front), presumably segregating or accumulating plankton communities.

Lethal by Design? Resolving Differences Between Experimental and Real‐World Alkalinity Perturbations in Ocean Alkalinity Enhancement

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ocean alkalinity enhancement (OAE) aims to mitigate climate change by increasing the chemical capacity of seawater to store anthropogenic CO2. OAE can be implemented through multiple pathways, each of which intentionally modifies marine carbonate chemistry through increases in total alkalinity (TA).

Spatial and temporal changes in macrobenthic communities in the Amazon coastal zone (Guajará Estuary, Brazil) caused by discharge of urban effluents

open access: yesScientia Marina, 2012
Spatial and temporal changes in the structure of soft-bottom macrobenthic communities caused by discharges of urban wastewater were studied in the Guajará Estuary, Amazon coastal zone, Brazil.

Ocean acidification, more than warming or heatwaves, constrains shoaling behaviour in a range‐extending fish through habitat simplification

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1386-1400, August 2026.
We show that ocean acidification, more than warming or marine heatwaves, alters shoaling behaviour indirectly by simplifying reef habitat and reducing population densities and shoal sizes. Because fish behaviour can be strongly mediated by shoal size, climate‐driven habitat change may reshape social dynamics that influence how range‐extending fishes ...
