Co-management between local communities and government agencies is promoted as a strategy to improve fisheries management. This paper considers the potential for co-management of sea turtle fisheries within four UK Overseas Territories (OTs) in the Caribbean, and for co-ordinated management among those territories. We focus on fisher incentives for engaging in co-management and on the potential to scale up co-management to a regional level. This paper presents data from Anguilla, British Virgin Islands, Montserrat, and Turks and Caicos Islands, where 110 turtle fishers participated in a socio-economic survey undertaken as part of the ‘Turtles in the UK Overseas Territories in the Caribbean’ project. Based on three established criteria for co-management (perceived crisis in stock, willingness to participate and community cohesion), results suggest that fisher support for co-management exists within each OT, but the extent of support for and views of specific management interventions varies among OTs. The implications of results for co-management in each territory, and for establishing co-ordinated management regimes in the region, are discussed in the context of current debates about the nature of resources and scalar (mis)matches between resource and management regimes. 相似文献

In general, the health of Poles improved markedly in the thirty years after the Second World War, but there was some deterioration
after 1989 before improvement resumed. Only in the case of cancer is there an upward trend and so Poles are now healthier
than they have been at any time in the past. However there are sharp regional variations well exemplified by the incidence
of tuberculosis, where there appears to be some correlation with poorer housing and atmospheric pollution. High death rates
in Lodz (consistently the highest in the country at the voivodship level between 1989 and 1996), may also be linked with environmental
pollution as well as the ageing of the population. Variations between town and country are small, but Poland shows up in a
poor light when compared with other European countries. These are important issues for the administration and financing of
the welfare services.

Results are discussed of an interview survey on consumer outshopping behaviour. Outshopping is defined and the survey area of Cwmbran New Town, UK, described. Two thirds of households are shown to be outshoppers. The frequency and extent of outshopping is analysed. The most common frequency is monthly with non-food purchases dominating buying habits at outcentres. The socio-economic characteristics of outshopper households are compared with those of local shoppers. The intensity of outshopping is considered and five types of outshopper isolated. Some determinents of outshopping behaviour are considered and price differentials appear to be a major trigger in the outshopper decision process. Other work on outshopping is discussed and compared with the results of the present survey. 相似文献

Two experimental populations of Gammarus duebeni have been found to contain high levels of what appeared to be pollutants in their gill neutral lipids. Detailed analysis, involving capillary gas chromatography-mass spectrometry, confirmed the presence of hydrocarbons, a plasticizer and silicone compounds. Such a localized concentration of lipophilic pollutants in a tissue such as the gills might be sufficient to influence the metabolism of the whole organism even though the total body burden is low. 相似文献

The fatty acid composition of the gill lipids from Gammarus duebeni have been compared in relation to the degree of contamination of the gills by lipophilic materials. The results indicate that at higher levels of gill contamination a greater proportion of polyunsaturated 20:5 fatty acid occurs in the gill phospholipids. We suggest this may be a response to a change in the physical state of the gill membranes resulting from the contamination. 相似文献

The Western Alps’ active tectonics is characterized by ongoing widespread extension in the highest parts of the belt and transpressive/compressive tectonics along its borders. We examine these contrasting tectonic regimes using a multidisciplinary approach including seismotectonics, numerical modeling, GPS, morphotectonics, fieldwork, and brittle deformation analysis. Extension appears to be the dominant process in the present-day tectonic activity in the Western Alps, affecting its internal areas all along the arc. Shortening, in contrast, is limited to small areas located along at the outer borders of the chain. Strike-slip is observed throughout the Alpine realm and in the foreland. The stress-orientation pattern is radial for σ3 in the inner, extensional zones, and for σ1 in the outer, transcurrent/tranpressional ones. Extensional areas can be correlated with the parts of the belt with the thickest crust. Quantification of seismic strain in tectonically homogeneous areas shows that only 10–20% of the geodesy-documented deformation can be explained by the Alpine seismicity. We propose that, Alpine active tectonics are ruled by isostasy/buoyancy forces rather than the ongoing shortening along the Alpine Europe/Adria collision zone. This interpretation is corroborated by numerical modeling. The Neogene extensional structures in the Alps formed under increasingly brittle conditions. A synthesis of paleostress tensors for the internal parts of the West-Alpine Arc documents major orogen-parallel extension with a continuous change in σ3 directions from ENE–WSW in the Simplon area, to N–S in the Vanoise area and to NNW–SSE in the Briançon area. Minor orogen-perpendicular extension increases from N to S. This second signal correlates with the present-day geodynamics as revealed by focal-plane mechanisms analysis. The orogen-parallel extension could be related to the opening of the Ligurian Sea during the Early-Middle Miocene and to compression/rotation of the Adriatic indenter inducing lateral extrusion. 相似文献
