Local Land-Use Planning to Conserve Biodiversity: Planners' Perspectives on What Works.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Because habitat loss due to urbanization is a primary threat to biodiversity, and land-use decisions in urbanizing areas are mainly made at the local level, land-use planning by municipal planning departments has a potentially important-but largely unrealized-role in conserving biodiversity. To understand planners' perspectives on the factors that facilitate and impede biodiversity conservation in local planning, we interviewed directors of 17 municipal planning departments in the greater Seattle (Washington, U.S.A.) area and compared responses of planners from similar-sized jurisdictions that were "high" and "low perf...

Comanagement Practices Enhance Fisheries in Marine Protected Areas.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Fishing activities worldwide have dramatically affected marine fish stocks and ecosystems. Marine protected areas (MPAs) with no-take zones may enhance fisheries, but empirical evidence of this is scant. We conducted a 4-year survey of fish catches around and within an MPA that was previously fully closed to fishing and then partially reopened under regulated comanaged fishing. In collaboration with the fishers and the MPA authority, we set the fishing effort and selected the gear to limit fishing impact on key fish predators, juvenile fish stage, and benthic communities and habitats. Within an adaptive comanagement fr...

Spontaneous Interspecific Hybridization and Patterns of Pollen Dispersal in Ex Situ Populations of a Tree Species (Sinojackia xylocarpa) that is Extinct in the Wild.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
For endangered plants interspecific hybridization occurring in ex situ collections may lead to failure of reintroduction actions. We used Sinojackia xylocarpa, a well documented Chinese endemic species that is extinct in the wild, as a model case to address this concern. We used paternity analyses to assess the spontaneous hybridization and patterns of pollen flow between S. xylocarpa and its congener species, S. rehderiana, in conserved populations in Wuhan Botanic Garden. Interspecific hybridization events were detected in seven out of eight maternal trees of S. xylocarpa, and an average of 32.7% seeds collected from...

Ecosystem Services as a Common Language for Coastal Ecosystem-Based Management.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Ecosystem-based management is logistically and politically challenging because ecosystems are inherently complex and management decisions affect a multitude of groups. Coastal ecosystems, which lie at the interface between marine and terrestrial ecosystems and provide an array of ecosystem services to different groups, aptly illustrate these challenges. Successful ecosystem-based management of coastal ecosystems requires incorporating scientific information and the knowledge and views of interested parties into the decision-making process. Estimating the provision of ecosystem services under alternative management sche...

Priority Wetland Invertebrates as Conservation Surrogates.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Invertebrates are important functionally in most ecosystems, but seldom appraised as surrogate indicators of biological diversity. Priority species might be good candidates; thus, here we evaluated whether three freshwater invertebrates listed in the U.K. Biodiversity Action Plan indicated the richness, composition, and conservation importance of associated wetland organisms as defined respectively by their alpha diversity, beta diversity, and threat status. Sites occupied by each of the gastropods Segmentina nitida, Anisus vorticulus, and Valvata macrostoma had greater species richness of gastropods and greater conser...

The Value of Species and the Ethical Foundations of Assisted Colonization.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Discourse around assisted colonization focuses on the ecological risks, costs, and uncertainties associated with the practice, as well as on its technical feasibility and alternative approaches to it. Nevertheless, the ethical underpinnings of the case for assisted colonization are claims about the value of species. A complete discussion of assisted colonization needs to include assessment of these claims. For each type of value that species are thought to possess it is necessary to determine whether it is plausible that species possess the type of value and, if so, to what extent their possessing it justifies assisted...

Influence of a Threatened-Species Focus on Conservation Planning.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conservation efforts at local, regional, and global scales often focus on threatened species despite recent calls to adopt more equitable and potentially more economically rational approaches. Critics contend that conservation planning centered only on threatened species fails to deliver cost-efficient conservation outcomes.

We found that the explicit protection of threatened species delivered cost-efficient outcomes in this situation, afforded adequa...

Effects of Harvest of Nontimber Forest Products and Ecological Differences between Sites on the Demography of African Mahogany.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The demographic impacts of harvesting nontimber forest products (NTFP) have been increasingly studied because of reports of potentially unsustainable harvest. Nevertheless, our understanding of how plant demographic response to harvest is altered by variation in ecological conditions, which is critical for developing realistic sustainable-use plans, is limited. We built matrix population models to test whether and how variation in ecological conditions affects population responses to harvest. In particular, we examined the effect of bark and foliage harvest on the demography of populations of African mahogany (Khaya se...

Devising Appropriate Policies and Instruments in Support of Private Conservation Areas: Lessons Learned from the Klein Karoo, South Africa.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The amount of privately conserved land is increasing worldwide. The potential of these areas to contribute to the global conservation of biodiversity is significant, given that statutory protected areas alone will not suffice. Nevertheless, there is still inadequate support for private conservation areas, and further research on appropriate, flexible, and generally applicable incentive measures is necessary. We conducted 25 semistructured interviews with the owners of private conservation areas in the Little Karoo, South Africa, to examine landowner opinions of existing conservation policies and their relationships wit...

Consistent Ecological Selectivity through Time in Pacific Island Avian Extinctions.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Understanding the ecological mechanisms that lead to extinction is a central goal of conservation. Can understanding ancient avian extinctions help to predict extinction risk in modern birds? I used classification trees trained on both paleoecological and historical data from islands across the Pacific to determine the ecological traits associated with extinction risk. Intrinsic traits, including endemism, large body size, and certain feeding guilds, were tightly linked with avian extinction over the past 3500 years. Species ecology and phylogeny were better predictors of extinction risk through time than extrinsic or ...

Effectiveness of Marine Protected Areas in the Philippines for Biodiversity Conservation.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Quantifying the extent to which existing reserves meet conservation objectives and identifying gaps in coverage are vital to developing systematic protected-area networks. Despite widespread recognition of the Philippines as a global priority for marine conservation, limited work has been undertaken to evaluate the conservation effectiveness of existing marine protected areas (MPAs). Targets for MPA coverage in the Philippines have been specified in the 1998 Fisheries Code legislation, which calls for 15% of coastal municipal waters (within 15 km of the coastline) to be protected within no-take MPAs, and the Philippine...

Demographic stability metrics for conservation prioritization of isolated populations.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Systems of geographically isolated habitat patches house species that occur naturally as small, disjunct populations. Many of these species are of conservation concern, particularly under the interacting influences of isolation and rapid global change. One potential conservation strategy is to prioritize the populations most likely to persist through change and act as sources for future recolonization of less stable localities. We propose an approach to classify long-term population stability (and, presumably, future persistence potential) with composite demographic metrics derived from standard population-genetic data...

Impact and dynamics of disease in species threatened by the amphibian chytrid fungus, Batrachochytrium dendrobatidis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Estimating disease-associated mortality and transmission processes is difficult in free-ranging wildlife but important for understanding disease impacts and dynamics and for informing management decisions. In a capture-mark-recapture study, we used a PCR-based diagnostic test in combination with multistate models to provide the first estimates of disease-associated mortality and detection, infection, and recovery rates for frogs endemically infected with the chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes the pandemic amphibian disease chytridiomycosis. We found that endemic chytridiomycosis was associ...

Conservation and aid: designing more effective investments in natural resource governance reform.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Biodiversity conservation outcomes are closely related to the rules and institutions governing resource use. Creating local incentives for conservation through more secure resource tenure is central to conservation outcomes on private and communal lands, where the preponderance of biodiversity occurs. Conservation efforts in sub-Saharan Africa are therefore centrally concerned with governance dynamics and institutional reform processes, such as the decentralization of property rights, and how best to achieve such reforms. Traditional mechanisms for financing conservation efforts in Africa rely heavily on funds channele...

Quantifying habitat requirements of tree-living species in fragmented boreal forests with Bayesian methods.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Quantitative conservation objectives require detailed consideration of the habitat requirements of target species. Tree-living bryophytes, lichens, and fungi are a critical and declining biodiversity component of boreal forests.

The importance of unexplained between-stand variation in occurrence of species was estimated, and the ability of derived models to predict species' occurrence ...

Moreover, we searched for a synergistic effect of these traits and of trophic level. We collected mined leaves and recorded plant, leaf miner, and parasitoid species interactions in five 100-m2 transects in 19 Chaco Serran...

World chocolate demand is expected to more than double by 2050. Decisions about how to meet this challenge will have profound effects on tropical rainforests and wild species in cocoa-producing countries.

The current trend to reduce or eliminate shade cover raises concerns about the potential loss of biodiversity. Nevertheless, few studies have assessed the ecological consequences and economic trade-offs under different management options in cocoa plantations. He...

Amphibians worldwide are facing rapid declines due to habitat loss and fragmentation, disease, and other causes. Where habitat alteration is implicated, there is a need for spatially explicit conservation plans. Models built with geographic information systems (GIS) are frequently used to inform such planning.

We used genetic assignment tests to characterize isolation of marbled salamander populations and evaluated whether the relative amount of modified habit...
