Sistemas socio-ecológicos como unidad de manejo: el caso de las pesquerías de Campeche, México

Economía, Sociedad y Territorio, 2021
La unidad de manejo más utilizada en pesquerías está limitada a las especies objetivo y sus especies asociadas. La finalidad de este estudio fue adecuar una metodología para regionalizar y caracterizar los sistemas socio-ecológicos (SSE) para la ...

Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia. [PDF]

Conserv Biol
Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Reconstructing historical catch trends of threatened sharks and rays based on fisher ecological knowledge. [PDF]

Conserv Biol
Abstract Small‐scale fisheries often lack historical shark and ray catch information, hampering their management. We reconstructed historical catch trends and current fishing pressure by combining local ecological knowledge, satellite‐based vessel counts, and a short‐term landing‐site survey.

Fine Characterization of the Contact Zones of <i>Mazzaella laminarioides</i> in the Southeastern Pacific Using Mitochondrial and Nuclear Markers. [PDF]

Ecol Evol
This study investigates the genetic structure of Mazzaella laminarioides, an ecologically and economically important species from the rocky coast of Chile. Using more accurate sampling and a set of microsatellite, nuclear, and mitochondrial markers, we were able to identify with high resolution the contact zones between the previously described ...

Evidence for a fisher-designed solution to manta and devil ray bycatch in tuna fisheries. [PDF]

Conserv Biol
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.

Key drivers of at-vessel mortality in demersal sharks. [PDF]

Conserv Biol
Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.

Insights on the roles of women in effective and procedurally just environmental governance from coastal fisheries management in Fiji. [PDF]

Conserv Biol
Women are widely viewed as the backbone of their villages, yet their participation in fisheries management is limited by restrictive gender roles. Men and women alike agree that women have valuable knowledge to contribute, and that men can serve as powerful allies.

A multiscale seasonal examination of the risk of harm to seabirds from vessels based on co-occurrence in Alaskan waters. [PDF]

Conserv Biol
Abstract Alaska's seascape supports globally significant seabird populations, including vulnerable and threatened species, and hosts economically important commercial fisheries and marine transportation corridors. Seasonal patterns of seabird movements and vessel traffic create a complex landscape of risk, defined as high levels of co‐occurrence ...

Importance and spatial patterns of invisible fisheries in Amazonian clear-water rivers as revealed by fisher knowledge and collaboration. [PDF]

Conserv Biol
The graphical abstract highlights the research collaboration with fishers through interviews to record fishers' knowledge and participatory monitoring, to provide data on small‐scale fisheries in three clear water rivers (Trombetas, Tapajos and Tocantins).
