The study of marine benthic resource beds can be undertaken using either an ecological approach, focused on the distribution patterns of the organisms, or a fishery approach, oriented to identify exploitable aggregations of economical interest. These two approaches are rarely brought together in the scientific literature. Herein, we characterized the spatial structuring of benthic resources in Chilean benthic resource management and exploitation areas (BRMEAs), a case of territorial use rights… 
Assessment of Exploitation Intensity of Commercial Species and Associated Benthic Communities, in Chilean Marine Management Areas of North Patagonia
The Aysén region of Chile (North Patagonia), has had limited studies on the effectiveness of management and exploitation areas of benthic resources, and performance relative to open access areas in
Using Drift Video Transects and Maximum Likelihood Geostatistics for Quantifying and Monitoring Exploited Subpopulations of Loxechinus albus at a Mesoscale
Abstract Population monitoring of benthic species has been complicated by difficulties in defining appropriate spatial units for making observations that are relevant to the management of these


Small-scale benthic fisheries in chile: on co-management and sustainable use of benthic invertebrates
We discuss the issues of sustainable use and management in the Chilean inshore benthic small-scale (artisanal) fisheries. The fishery benefits from two features that make it possible to overcome some
Community patterns generated by human harvesting on Chilean shores: a review
Three clear patterns were identified depending on the trophic level adopted by the human gatherers in the food chain of the intertidal zone, which contribute to the evaluation of the state of conservation of the Chilean rocky intert tidal shores.
Patch dynamics of mussels on rocky shores: Integrating process to understand pattern
Comparing the dynamics of natural and experimentally constructed mussel patches in two intertidal habitats, tidepools and emergent rock, and among seasons shows the relative importance of physical and biological processes in determining patch size and structure.
Demographic Theory for an Open Marine Population with Space-Limited Recruitment
A demographic model for a local population of sessile marine invertebrates that have a pelagic larval phase is introduced and suggests that two qualitatively distinct pictures of population structure result, depending on the settlement rate.
Temporal persistence of biological patch structure in an abyssal benthic community
An analysis of living and dead components of a population of deep-sea agglutinated Foraminifera reveals that both segments of the fauna are dispersed nonrandomly on a scale of centimeters, suggesting that dispersion pattern is the result of an active interaction between amimals and a heterogeneous physical and biotic environment.
Although mussel predators were unable to decimate mussels to local extinction, a release of experimental mussel patches from predation with strong recruitment resulted in an approximately sevenfold yearly areal increase in shallow treatments, which would lead to a 100% mussel cover at the site within 1 yr.
Variation and persistence of the middle rocky intertidal community of central Chile, with and without human harvesting
The effects of the exclusion of humans from the rocky intertidal at Las Cruces, central Chile are reported on and species diversity and composition in harvested and non-harvested areas diverged.
The Pisaster-Tegula Interaction: Prey Patches, Predator Food Preference, and Intertidal Community Structure
Analysis of relative growth and reproduction indicates that beyond a certain size (16 mm) large individuals perform less well in the upper than those in the lower intertidal zone, and the zoogeographic homogeneity of the Pacific rocky coastline community are discussed in relation to three intermeshing ecological processes.
