Compared with mammals and birds, plants are underrepresented in translocation programs, and little is known about the potential taxonomic and phylogenetic biases of plant translocation efforts. We aimed to assess how translocated plant species may contribute to the conservation of phylogenetic diversity (PD) among European countries. Focusing on angiosperms across 4 European countries with well-documented flora and comprehensive sampling of translocated plant species, we determined whether species translocations were related to species conservation status with binomial generalized linear mixed models with threat status as a binary response variable. Then, we evaluated the taxonomic and phylogenetic biases of translocated plant species relative to national floras based on PD and evolutionary distinctiveness (ED). To evaluate PD and ED, we constructed null models to assess the deviation of observed values from those expected under a scenario in which translocated species were randomly sampled from the species pool of national floras in each country. Although most species lacked conservation status assessment, plant translocations mainly targeted species with high extinction risk at national, European, and global scales. Although plant orders with a higher representativeness of translocated species also tended to have a higher representativeness of native species, the probability of species being translocated varied significantly across plant order, suggesting a significant taxonomic bias. Based on null models and considering all countries, PD and mean ED of translocated plants were higher than expected by chance in most countries. These results suggest that although translocation programs were implemented independently across countries, the diversity of translocated plant species is relevant to conserving PD from national to continental scales and restoring evolutionarily distinct species when these species succeed. We argue that PD indicators should be incorporated into translocation planning to restore target species' evolutionary trajectories and to contribute to conservation of PD.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":" ","pages":"e14451"},"PeriodicalIF":5.2,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143064128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She focuses on power in conservation and provides a toolbox of ideas about power relations for users, not simply readers—as she emphasizes. “Most power is well meaning. Most power in conservation does not even know itself as power or as governing. This book is about those sorts of power”—she writes. Money, influence, and coercive control—this is what people often understand under power, but as Carpenter argues, “most of the power in conservation lies with mistaken assumptions conservationists hold about people, misunderstandings about their relation with the environment, and assumptions about our own superior knowledge, and our sense that we have a right to intervene based on that assumed superior knowledge.” The book introduces the different understanding of power by Marx and Foucault and shows what we can learn if we replace the winner and looser opposition of Marx, where power is a fixed property of some agents, with examining concretely how power is generated by and located in different strategies of government, as suggested by Foucault. Carpenter shows, using a great selection of local ethnographies, that the how question is best answered by nuanced ethnographic accounts, where people and nature are seen as inextricably interwoven parts of the same complex system.

In the western Indian Ocean, this situation is exacerbated by limited population data on these fishes, including from conventional visual census methods, which limit the surface area surveyed. We developed a rapid timed scuba swim survey approach for application over large areas for estimation of the abundance of large-bodied reef fishes and assessment of the effectiveness of marine protected areas (MPAs) in maintaining these species' populations. Using this method, we sampled 7 regions in the western central Indian Ocean and Gulf of Aden, including 2 remote reference locations where fishing is prohibited.

We considered whether taking an interdisciplinary approach to parasite conservation research will generate novel insights and solutions concerning why and how parasite conservation should be practiced for the benefit of parasites, their hosts, ecosystems, and people. We argue that 2 of the main barriers to more widespread parasite conservation are the knowledge gap concerning the role of sociocultural factors affecting the willingness to enact parasite conservation and the lack of a consistent and cohesive philosophical basis for parasite conservation. Possible sociocultural barriers to parasite conservation include misconceptions of the risks posed by parasites, taxonomic bias, differences in conservation values, economic constraints, and technical challenges. The use of social science can generate insights into levels of awareness and support for parasite conservation and improve understanding of how human values and attitudes mediate conservation practices concerning parasites. Such knowledge will have a critical role in addressing sociocultural barriers and improving support for parasite conservation. Issues with the current philosophical basis for parasite conservation include contradictory accounts of which parasites merit conservation, insufficient explanation of how different conservation values apply to parasite biodiversity, and the existence of a false antagonism between host and parasite conservation.

Recent research modeling coral reef fisheries globally has estimated multispecies sustainable reference points (i.e., the maximum reef fish yields that can be harvested sustainably and the corresponding reef fish standing biomass at which those are expected to be achieved) based on environmental indicators. These global reference points are a promising tool for assessing data-poor reef fisheries but need to be downscaled to be relevant to resource practitioners. Using a small-scale multispecies reef fishery in Papua New Guinea, we estimated sustainable reference points and assessed the sustainability of the fishery by integrating global-scale analyses with local-scale environmental conditions (i.e., coral cover, sea surface temperature, ocean productivity, and whether the reef is an atoll), reef area, fish catch and standing biomass estimates, and fishers' perceptions. Local-scale relevant data were obtained from a combination of remote sensing products, underwater visual censuses, catch surveys, and household structured social surveys. Our sustainability assessment based on downscaled estimated sustainable reference points was consistent with local fishers' perceptions. Specifically, our downscaled results suggested that the fishing community was overfishing their reef fish stocks and stocks were below biomass levels that maximize production, making the overall reef fishery unsustainable. These results were consistent with fisher perceptions that reef fish stocks were declining in abundance and mean fish length and that fishers had to spend more time finding fish. Our downscaled site-level assessment revealed severe local resource exploitation, the dynamics of which were masked in national-scale assessments, emphasizing the importance of matching assessments to the scale of management.
