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 of Lake Orta in the year 1996

Journal of Limnology, 2001
Lake Orta has been interested since 1926 by severe industrial pollution, due to the effluents of a rayon (artificial silk) factory that discharged huge amounts of copper and ammonia.

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.

Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

Journal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Energy Flows in the Vistula Lagoon of the Baltic Sea [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2012
Energies of the Vistula Lagoon ecosystem is estimated based on observations made by authors in the northern Vistula Lagoon literature data. The pelagic and bottom communities are represented by euryhaline species: phytoplankton - 412, zooplankton - 74 ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Feasibility of restoring native oyster reefs in highly modified urban estuaries

Restoration Ecology, EarlyView.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

Limited effects of structural restoration on ecosystem functioning in an urban tropical stream

Restoration Ecology, EarlyView.
Abstract Introduction Hydromorphological restoration through structural interventions is commonly used to mitigate urbanization impacts on lotic freshwater systems, but their effects on ecosystem functioning in urban tropical streams remain unexplored.

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.
