Environmental Impacts of the Bioeconomy: A Systematic Review of Variables, Methods, Sectors and Policy Relevance

Sustainable Development, EarlyView.
ABSTRACT The bioeconomy has become a component of sustainability strategies addressing climate change, resource scarcity and economic transformation. Despite a growing body of literature, evidence on the environmental impacts of the bioeconomy remains fragmented, heterogeneous and distributed across sectors and regions. This paper provides a systematic

Threats to Our Ocean Heritage: Bottom Trawling [PDF]

This open access book focuses on the destruction of our Ocean Heritage from bottom trawling. It brings together the natural and cultural sides of the marine environment to further our understanding of the importance of this heritage, how it is threatened

Ecosystem Functioning Under the Influence of Bottom-Trawling Disturbance: An Experimental Approach and Field Observations From a Continental Slope Area in the West Iberian Margin

Frontiers in Marine Science, 2020
Understanding the effects of bottom-trawling induced changes in benthic community structure, diversity and ecosystem functioning across different benthic-size components is imperative to determine the future sustainability of bottom-trawling fisheries in

Comparing environmental metabarcoding and trawling survey of demersal fish communities in the Gulf of St. Lawrence, Canada

Environmental DNA, 2021
Biodiversity assessment is an important part of conservation management that ideally can be accomplished with noninvasive methods without influencing the structure and functioning of ecosystems.

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Ecological and economic effects of banning bottom trawling in Natura 2000 sites and reducing its effort in the western Mediterranean

Ecological Indicators
In the Mediterranean Sea, several fished stocks remain overexploited and several marine protected areas (MPAs) permit high-impact gears such as bottom trawling.

Trawling in the Mediterranean: An Exploration of Empirical Relations Connecting Fishing Gears, Otterboards and Propulsive Characteristics of Fishing Vessels

Frontiers in Marine Science, 2019
Fishing pressure is often expressed in terms of a vessels physical attributes, like tonnage and engine power, while a common definition of fishing capacity identifies vessel size as a convenient proxy for the size of the gear used.

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

Wildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Long‐term recovery and food web response of benthic macrofauna following cessation of bottom trawling in a marine protected area

Conservation Science and Practice
The understanding of the depletion of species and communities and recovery following the reduction of pressures is fundamental in conservation biology. The impact of bottom trawl fisheries on benthic communities has been well studied, but there are few ...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,
