Taxonomic and phylogenetic biases in translocated angiosperm plant species across European countriesNARA Subscribed
Conservation translocations are a well‐known conservation tool used to reverse the effects of local population extinctions and restore ecosystems. 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 p...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
Achieving conservation outcomes in plant mitigation translocations: the need for global standardsNARA Subscribed
Many countries have legislation intended to limit or offset the impact of anthropogenic disturbance and development on threatened plants. Translocations are often integral to those mitigation policies. When translocation is used exclusively to mitigate development impacts, it is often termed a ‘mitigation translocation.’ However, both the terminology and processes vary regarding interpretation and application, resulting in inc...
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the NeotropicsNARA Subscribed
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos,...

Role of Corridors in Plant Dispersal: an Example with the Endangered Ranunculus nodif lorusNARA Subscribed
The proposition that the migration of organisms between habitat patches could be enhanced by corridors has been much discussed among conservation biologists. But the few experimental studies supporting the usefulness of corridors have all concerned animal species. We investigated the role of corridors in seed dispersal, studying population genetic and demographic structure in metapopulations of the rare, pond‐dwelling, autogam...
Population structure of an endangered species living in contrasted habitats: Parnassia palustris (Saxifragaceae)NARA Subscribed
In endangered species, it is critical to analyse the level at which populations interact (i.e. dispersal) as well as the levels of inbreeding and local adaptation to set up conservation policies. These parameters were investigated in the endangered species Parnassia palustris living in contrasted habitats. We analysed population structure in 14 populations of northern France for isozymes, cpDNA markers and phenotypic traits re...
Fire and species range in Mediterranean landscapes: an experimental comparison of seed and seedling performance among Centaurea taxaNARA Subscribed
Aim Fire is a major disturbance event in Mediterranean landscapes. In this paper, we experimentally assess the effects of fire and post‐fire conditions on seed germination and establishment of twenty Centaurea taxa to test whether differences among taxa are associated with range size. Methods The taxa (species and subspecies) considered were classified as rare and widespread according to their `area of occupancy' in the Medite...
Predicting Endemism from Population Structure of a Widespread Species: Case Study in Centaurea maculosa Lam. (Asteraceae)NARA Subscribed
Amounts of genetic variability, genetic differentiation among taxa and populations, and population sizes were studied in five populations of Centaurea maculosa ssp. maculosa (a widespread taxon), all six populations of C. corymbosa (a narrowly endemic species), and the single population of C. maculosa ssp. albida . Seventeen isozyme loci were studied, of which nine were polymorphic. Results suggest that C. corymbosa and C. mac...
