TL;DR: A novel method is used to compare the current network placement to results produced from Zonation prioritisation software and suggests that the method could be used to model the optimal PA network for a wide range of species and/or regions, something which will support the assessment and attainment of CBD targets.

TL;DR: Assessments of site suitability should be undertaken, focusing on food availability and isolation from predators to maximise the likelihood of attaining levels of productivity and survival that avoid creation of a sink population to the detriment of the overall metapopulation size.
Abstract: Habitat management to restore or create breeding sites may allow metapopulations to increase in size and reduce the risk of demographic stochasticity or disasters causing metapopulation extinction. However, if newly restored or created sites are of low quality, they may act as sinks that draw individuals away from better quality sites to the detriment of metapopulation size. Following intensive conservation effort, the metapopulation of roseate tern (Sterna dougallii) in NW Europe is recovering from a large crash in numbers, but most former colonies remain unoccupied and hence are potential targets for restoration. To inform conservation efforts, we studied the dynamics of this metapopulation with a multistate integrated population model to assess each of the three main colonies for important demographic contributors to population growth rate, source/sink status and possible density dependence. All three study colonies are managed for roseate terns (and other tern species) in similar ways, but the demographic processes vary considerably between colonies. The largest colony is a source involved in almost all dispersal, and its growth is determined by survival rates and productivity. Productivity and juvenile apparent survival at the largest colony appear to be density-dependent. Although the mechanisms are unclear, this may provide an increasing impetus for emigration of recruits to other colonies in future. The smallest of the three colonies is a sink, relying on immigration for its growth. Simulation models suggest the metapopulation would be c. 10% larger in the absence of dispersal to the sink colony. This work indicates that, due to variable site quality, aims to enhance both distribution and size of metapopulations may be mutually exclusive. In this case, before future attempts to encourage recolonisation of former sites, assessments of site suitability should be undertaken, focusing on food availability and isolation from predators to maximise the likelihood of attaining levels of productivity and survival that avoid creation of a sink population to the detriment of the overall metapopulation size.

TL;DR: Drawing on three MPA processes currently occurring in the UK North Sea, this work examines the real-world problems that make the designation of MPA networks challenging and argues for a more pragmatic approach to marine protection that embraces the complexity of the social and political arena in which decisions are made.
Abstract: The North Sea is one of the most economically important seas in the world due to productive fisheries, extensive oil and gas fields, busy shipping routes, marine renewable energy development and recreational activity. Unsurprisingly, therefore, the use of marine protected areas (here defined widely to include fisheries closed areas and no-take marine reserves) in its management has generated considerable controversy-particularly with regards to the design of a regional ecologically coherent MPA network to meet international obligations. Drawing on three MPA processes currently occurring in the UK North Sea, we examine the real-world problems that make the designation of MPA networks challenging. The political problems include: disagreement among (and within) sectors over policy objectives and priorities, common access to fisheries resources at the EU level increasing the scale at which decisions have to be made and lack of an integrated strategy for implementing protected areas in the North Sea. The scientific problems include the patchy knowledge of benthic assemblages, limited knowledge of fishing gear-habitat interactions, and the increased risk of unforeseen externalities if human activity (predominantly fishing) is displaced from newly protected sites. Diverging stakeholder attitudes to these problems means that there is no consensus on what ecological coherence actually means. Ultimately, we caution against 'quick-fix' solutions that are based on advocacy and targets, as they create confusion and undermine trust in the planning process. We argue for a more pragmatic approach to marine protection that embraces the complexity of the social and political arena in which decisions are made.

TL;DR: In this article, the authors compared the breeding biology of urban and rural populations of a very common old-world raptor, the Eurasian sparrowhawk (Accipiter nisus).
Abstract: The conversion of rural habitat into built-up areas often affects animal species negatively. However, some generalist bird species and raptors relying on avian prey have colonised urban environments. Surprisingly, no study has compared the breeding biology of urban and rural populations of a very common old-world raptor, the Eurasian sparrowhawk (Accipiter nisus). Here, we compare the territory occupancy rate, breeding success and productivity (i.e., the number of fledglings) over four years (2009–2012) of an urban and a rural sparrowhawk population in Scotland. Our results showed that urban sparrowhawk territories were occupied significantly more frequently (mean % years occupied ± se: 66.8 ± 5.9%) than rural territories (42.8 ± 4.7%). Clutch size, brood size and the number of fledglings produced did not differ between the populations. However, the breeding success was significantly higher in the urban (annual mean ± se: 97.2 ± 2.3% nests successful) than in the rural population (80.5 ± 6.6%) bec...
