European bird declines: do we need to rethink approaches to the management of abundant generalist predators?
<ol> <li>Bird species are declining across Europe. Current European policy, i.e. the Birds and Habitats Directives, focus on habitat management as a way of halting the declines. This paper explores the role of predation in causing bird population declines and asks if we need to reconsider our approach to the management of generalist predators. </li> <li>We analysed bird population trends and distribution changes across Europe, Britain and Ireland, reflecting an increasing gradient of generalist predator abundance (principally red fox <i>Vulpes vulpes </i>and species of the family <i>Corvidae</i>). We tested if ground-nesting bird species, considered more vulnerable to predation,were in greater decline compared to other nesting strategies. We also compared Annex I designated species to non-designated species as a proxy for habitat management.</li> <li>We found that across Europe, 74% of ground-nesting bird species were in decline, compared to 41% of other species. This was especially evident in Britain, where the pattern was 66% compared to 31%, and in Ireland, 71% compared to 20%. Ground-nesting species were significantly more likely to be declining than other species.</li> <li>These patterns are consistent with the idea that population declines are at least partially related to the increased abundance of generalist predators. In Britain, ground-nesting species were less likely to be in decline if covered by Annex I designation. However, in Europe and Ireland, Annex I status did not mitigate the effect of nesting strategy. </li> <li> <i>Policy implications</i><span><span><span><span><span><span><span><span><span><span><span>. Current legislation is clearly insufficient to prevent widespread declines in ground-nesting birds, and this is the case across Europe, in Britain and Ireland. Ignoring the role of generalist predators in modern landscapes may lead to further declines and losses. We urgently need large-scale experiments to establish causality in the impact of generalist predators on ground-nesting birds in different landscapes. If we value our ground-nesting bird species, consideration needs to be given to the control of widespread generalist predators, at least until landscapes are restored.</span></span></span></span></span></span></span></span></span></span></span> </li> </ol> <div> <div> <div class="msocomtxt"> <p class="MsoCommentText"> </p> </div> </div> </div>
Data from: Predator-prey trophic relationships in response to organic management practices
A broad range of environmental conditions likely regulate predator-prey population dynamics and impact the structure of these communities. Central to understanding the interplay between predator and prey populations and their importance is characterizing the corresponding trophic interactions. Here we use a well-documented molecular approach to examine the structure of the community of natural enemies preying upon the squash bug, Anasa tristis, a herbivorous cucurbit pest that severely hinders organic squash and pumpkin production in the United States. Primer pairs were designed to examine the effects of organic management practices on the strength of these trophic connections and link this metric to measures of the arthropod predator complex density and diversity within an experimental open-field context. Replicated plots of butternut squash were randomly assigned to three treatments and were sampled throughout a growing season. Row-covers treatments had significant negative effects on squash bug and predator communities. In total, 640 predators were tested for squash bug molecular gut-content, of which 11% were found to have preyed on squash bugs, but predation varied over the season between predator groups (coccinellids, geocorids, nabids, web-building spiders and hunting spiders). Through the linking of molecular gut-content analysis to changes in diversity and abundance, these data delineate the complexity of interaction pathways on a pest that limits the profitability of organic squash production.
