Conservation of limpet populations: a heavily exploited resource in Azores, NE-...

10th International Temperate Reefs Symposium, The University of Western Australia, 12-17 de janeiro. ; Limpet harvesting in Azores (NE Atlantic) has been taking place probably since the islands were first colonized in the XV century. Limpet species are highly exploited and populations from most islands have declined steadily bringing about catastrophic effects on coastal communities. Despite their economic imp...

Conectividade em populações de lapas nas ilhas da Macaronésia (Atlântico-NE): u...

Jornadas "Ciência nos Açores – que futuro? Tema Ciências Naturais e Ambiente", Ponta Delgada, 7-8 de Junho de 2013. ; De uma forma geral, é consensual que a sobre-exploração de um dado recurso natural exerce um impacto profundo na respectiva comunidade, sobretudo quando se trata de uma espécie chave para o ecossistema. Por exemplo, as lapas que têm tradicionalmente sido exploradas para consumo humano em todos ...

Temporal variation in reproductive phenology of Patella spp.: past and present.

World Congress of Malacology, Universidade dos Açores, Ponta Delgada, 21-28 de julho. ; Global changes occurring in the biogeochemistry o f the oceans may influence the ecology of the biota. There is evidence that species are reacting to changes in climate through variations in the abundance and phenology with many species showing a poleward shift in their distributional range. The rocky intertidal is a relati...

Evidence of long-term changes in the distribution of key intertidal species

World Congress of Malacology, Ponta Delgada, July 22-28, 2013. ; Globally, changes are occurring in the biogeochemistry and ecology of the oceans, which may influence the physiology, phenology, and species distribution. Biological communities are reacting to climate change through changes in the abundance and phenology of the organisms and through the poleward shift in species distribution. Rocky shores are re...

Synthesis of meeting and recommendations from the Net-Biome round table discuss...

Net-Biome Final Meeting (Paris, 15 & 16 February, 2012). ; This brief report summarizes the deliberations of the Round-Table presentations and discussion held during the Net-Biome Final Meeting (Paris, 15 & 16 February, 2012). The participants identified relevant key issues to support of Biodiversity management and underpinning science in ORs and OCTs. Two major themes emerged: a) Policy context and engagement...

Illegal harvesting affects the success of fishing closure areas.

Copyright © Marine Biological Association of the United Kingdom 2010. ; There is clear evidence that marine reserves can be used as effective tools to foster the recovery of disturbed ecosystems. In the Azores, intense exploitation of the patellid limpets Patella candei and P. aspera has led to a rapid decline in their populations and subsequent collapse of the fishery in 1985. In 1993, legislation was passed ...

Exploitation of keystone species: population and community-level effects

Recruitment, growth and population size structure of Pollicipes pollicipes in S...

A general model for the life cycle of Pollicipes pollicipes in SW Portugal is proposed integrating results from a study on recruitment, growth and population size structure. A brief summary of literature concerning Pollicipes published since Margaret Barnes' review paper of 1996 is presented. Recruitment of P. pollicipes on conspeci␣cs (number of cyprids and juveniles with Rostro-Carinal length (RC) b 0.6 mm pe...

Enhancing stocks of the exploited limpet Patella candei d'Orbigny via modificat...

Copyright © 2009 Elsevier Ltd. All rights reserved. ; It is widely recognised that microhabitats are important for a variety of marine organisms, yet this knowledge has rarely been applied in the construction of engineered structures as a means of enhancing biodiversity or populations of species at risk. Here we examined the influence of microhabitats on the distribution and survival of the exploited limpet Pa...
