AbstractKnowledge on how environmental factors shape the genome of marine species is crucial for sustainable management of fisheries and wild populations. The edible cockle (Cerastoderma edule) is a marine bivalve distributed along the Northeast Atlantic coast of Europe and is an important resource from both commercial and ecological perspectives. We performed a population genomics screening using 2b-RAD genotyping on 9,309 SNPs localised in the cockle’s genome on a sample of 536 specimens pertaining to 14 beds in the Northeast Atlantic to ascertain its genetic structure regarding environmental variation. Larval dispersal modelling considering species behaviour and interannual variability in ocean conditions was carried out, as an essential background to compare genetic information with. Cockle populations in the Northeast Atlantic were shown to be panmictic and displayed low but significant geographical differentiation across populations (FST = 0.0240; P < 0.001), albeit not across generations. We identified 441 outlier SNPs related to divergent selection, sea surface temperature being the main environmental driver following a latitudinal axis. Two main genetic groups were identified, northwards and southwards of French Brittany, in accordance with our modelling, which demonstrated a barrier for larval dispersal linked to the Ushant front. Further genetic subdivision was observed using outlier loci and considering larval behaviour. The northern group was divided into the Irish/Celtic Seas and the English Channel/North Sea, while the southern group was divided into three subgroups. This information represents the baseline for management of cockles, designing conservation strategies, founding broodstock for depleted beds, and producing suitable seed for aquaculture production.

The globalization of the economy encourages massive population displacements and inevitably generates a cosmopolitization of societies. This leads to concern, misunderstanding and rejection. The most vulnerable social groups in society can perceive the population as intruders and enemies in social competition. Undoubtedly, the extreme spatial instability of fishery resources is among the many factors affecting migration dynamics. Various reasons for the mobility of fishermen are relevant around this concept. These include aspect related to traditions, to the capitalisation of activity, to technological innovations, and to innovation exchanges concerning the location of fish stocks. This article reflects on spatial increase of fishermen’s. The analyse are part of the paradigm of the sustainable management of common renewable resources, in particular fishery resources. It presents three lines of analysis: the reason for mobility; the choice of destination; and are the integration into host units.

This paper highlights the lessons of using adaptive learning in community forestry that effectively help to resolve forest based conflicts in Terai region of Nepal. The paper is based on a three-year action research carried out in Terai. Qualitative methods including participatory rural appraisal tools and documentation of engaged action and reflections were used. Methods and tools that largely fall under adaptive learning were deployed. The field data was complemented by review of secondary data and literature on environmental history of Terai. We found that policies on land and forest in Terai for the last fifty years have induced and aggravated conflicts over access and control between state and communities and also within diverse groups of local communities. These conflicts have had serious negative impacts on sustainable management of forests and on local people’s livelihoods, particularly resource poor and landless people. Centralised and bureaucratic approaches to control forest and encroachment have largely failed. Despite investing millions of Rupees in maintaining law and order in forestlands, the problem continues to worsen often at the cost of forests and local communities. We found that transferring management rights to local communities like landless and land poor in the form of community forestry (CF) has induced strong local level collective action in forest management and supported local livelihoods. Moreover, adding adaptive learning, as a methodological tool to improve governance and enhance local level collective action significantly improves the benefit of CF. It implies that a major rethinking is needed in the current policies that have often led to hostile relationships with the local inhabitants- particularly the illegal settlers. Instead, transferring forest rights to local communities and supporting them through technical aspects of forest management will strengthen local initiatives towards sustainable management of forests.
