Nature Climate Change, 2019
With climate change, marine species are on the move and changing in abundance. Now, research shows that the ecological impacts of climate change will differentially affect fishing communities, even within the same region.

Fish community responses to metal pollution
Environmental Pollution, 2005The effect of metal pollution on fish communities was assessed at 47 sites, including a Cd and Zn gradient. Fish community structure was assessed by applying diversity indices, index of biotic integrity and the abundance/biomass comparison method (ABC-index).

This chapter uses the community model to repeat many of the classic impact calculations of a single stock on the entire community. Here, a focus is the appearance of trophic cascades initiated by the removal of large predators. When a component of an ecosystem is perturbed, the effects are not isolated to the component itself but cascade through the ...

Effects of trap fishing on reef fish communities
Aquatic Conservation: Marine and Freshwater Ecosystems, 2006Abstract Trap fishing is widespread on coral reefs but the sustainability of this practice is causing concern because it is efficient and unselective. The effects of trap fishing were investigated by comparing fish assemblages among six Caribbean islands subject to different trapping pressures.

Visual Communication in Fishes
1980The intensity and spectral distribution of the light encountered by an animal species set reasonably broad operational limits for the efficient generation and reception of visual signals. This phenomenon is of special importance to fishes because aquatic environments cause profound changes in the nature of light that penetrates to any depth (Blaxter ...

1991
Abstract There is a remarkable benthic fish community in deep water in Lake Tanganyika that is rich in endemic species and genetically diverse. Its lower limit is determined by oxygen concentration, some species ranging down to about 200 m depth at the south of the lake where the oxygenated layer is deepest.

Density-Dependent Coexistence in Fish Communities
Ecology, 1998A set of stage-structured competition models is considered. The models are parameterized using allometric relationships specific to four fish life history strategies, constraining the model to biologically plausible regions in parameter space. Using a coupled consumer–resource competition model, I get the paradoxical result that two populations can ...

Understanding the Fishing ‘Community’: The Role of Communities of the Mind
Sociologia Ruralis, 2015AbstractThis article explores what is meant by the term fishing ‘community’ by evidencing shared ‘communities of the mind’ from people living and working in coastal areas linked to fishing. Using empirical data collected through in‐depth interviews and participant observation in three Scottish case‐study locations, this article identifies three key ...
