Abundance, Diversity and Distribution of Benthic Macro-Invertebrates in the Flat Bayou Drainage Area, Jefferson County, Arkansas [PDF]
, 1979 The main ditch of Flat Bayou Drainage in north central Jefferson County carries water southward into Plum Bayou which then shortly empties into the Arkansas River.

Dual stable isotope abundances unravel trophic position of estuarine nematodes [PDF]
, 2005 The role and quantitative importance of free-living nematodes in marine and estuarine soft sediments remain enigmatic for lack of empirical evidence on the feeding habits and trophic position of most nematode species.

Tracking the impact of bottom trawling on benthic habitat status
Conservation Biology, EarlyView.Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Benthos Ecology Working Group (BEWG) [PDF]
, 2020 The Benthos Ecology Working Group (BEWG) aims to study, describe and update on all aspects relevant to the ecology, functioning and interactions of marine benthic species (living in or within the sediment), either macro, meio and epifauna across the North Eastern Atlantic.

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Influence of Trophic Relations in the Shelf Communities on Benthos: Trophic Structure and the Effects of Grazing Pressure [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2013 Influence of the plankton and nekton on the benthos, which form total shelf community is considered. Trophic structure of benthos of different parts of the World Ocean shelves has been reviewed and made its classification.

EFFECTS OF TOWED DEMERSAL FISHING GEAR ON BIOGENIC SEDIMENTS: A 5-YEAR-STUDY [PDF]
, 2000 Experimental scallop fishing was carried out using towed commercial dredges on sediments deposited by unattached coralline algae in order to quantify their sensitivity to damage from current fishing practices.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates
Journal of Fish Biology, EarlyView.Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Journal of Phycology, EarlyView.Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).

Knowledge and Management of Aquatic Ecosystems, 2016 Biotic changes and a salinity increase (from 13 to 40 g.L-1) occurred in Lake Qarun (Egypt) since 1901. Was salinity increasing a cause of observed biotic changes? To answer this question we used benthos as a model group.
