Bethencourtia Choisy ex Link is an endemic genus of the Canary Islands and comprises three species. Bethencourtia hermosae and Bethencourtia rupicola are restricted to La Gomera, while Bethencourtia palmensis is present in Tenerife and La Palma. Despite the morphological differences previously found between the species, there are still taxonomic incongruities in the group, with evident consequences for its monitoring and conservation. The objectives of this study were to define the species…

Understanding Diversity and Systematics in Australian Fabaceae Tribe Mirbelieae
Novel analyses of available plastid DNA data (trnL-F) suggest that option two of the Pultenaea alliance in tribe Mirbelieae would be feasible once sufficient data are generated to resolve relationships, but the reticulate evolutionary histories or past rapid speciation suggested for this group may prevent the resolution of all nodes.
Molecular evidence of species- and subspecies-level distinctions in the rare Orchis patens s.l. and implications for conservation
This study evaluated levels of genetic diversity and population structuring using 12 new nuclear microsatellite markers and provided support for the recognition of O. canariensis as a sister species to O. patens and the Italian populations as a new subspecies of the species.
Revised Species Delimitation in the Giant Water Lily Genus Victoria (Nymphaeaceae) Confirms a New Species and Has Implications for Its Conservation
This study demonstrates how combining different types of character data into a heuristic, total-evidence approach can enhance the reliability with which biological diversity of morphologically challenging groups can be identified, documented and further studied.
The restoration of the endangered Sambucus palmensis after 30 years of conservation actions in the Garajonay National Park: genetic assessment and niche modeling
To optimize future reintroductions of Sambucus palmensis, a list of specimens that are suitable for the extraction of seeds or cuttings in a greenhouse, as well as new suitable areas obtained by the species distribution models are proposed.
Alpine species in dynamic insular ecosystems through time: conservation genetics and niche shift estimates of the endemic and vulnerable Viola cheiranthifolia
The simulations to estimate genetic diversity loss show that it is correlated to suitability loss, especially in Las Cañadas Wall, and conservation actions should be focused on herbivore control, population reinforcement and surveillance of niche shifts.
Evolution and conservation genetics of an insular hemiparasitic plant lineage at the limit of survival: the case of Thesium sect. Kunkeliella in the Canary Islands.
PREMISE The diversification of island flora has been widely studied. However, the role of environmental niches in insular radiation processes has been less investigated. We combined population


Key Processes for Cheirolophus (Asteraceae) Diversification on Oceanic Islands Inferred from AFLP Data
It is hypothesized that current threat categories assigned to Macaronesian Cheirolophus species do not reflect their respective evolutionary relevance, so future evaluations of their conservation status should take into account the results presented here.
Molecular markers reveal no genetic differentiation between Myrica rivas-martinezii and M. faya (Myricaceae).
Considering that M. rivas-martinezii is classified as at risk of extinction, there should be a change of focus of the current management actions for the conservation of this putatively endangered Canarian endemic.
Contrasting patterns of genetic differentiation in Macaronesian lineages of Ilex (Aquifoliaceae)
The Macaronesian Ilex taxa show that long-distance dispersal syndromes (ornithochory) do not always ensure genetic connectivity across large areas in island systems.
High genetic diversity and population structure in the endangered Canarian endemic Ruta oreojasme (Rutaceae)
The results support the observation that Canarian endemics are characterised by unexpectedly high genetic diversity and provides important insights for potential applications to the conservation of R. oreojasme.
Microsatellite markers unravel the population genetic structure of the Azorean Leontodon: implications in conservation
The results update the current distribution given for theAzorean Leontodon taxa, clearly indicating that conservation measures should be applied to several populations and reveal that a revision of the Azorean Le ontodon should be carried out to clarify species delimitation.
Conservation genetics of the endangered endemic Sambucus palmensis Link (Sambucaceae) from the Canary Islands
The levels of genetic differentiation observed among populations, and the genetic diversity distribution within populations in S. palmensis, indicate that management should aim to conserve as many of the small populations as possible.
Plant genetic diversity in the Canary Islands: a conservation perspective.
A review of allozyme variation in 69 endemic species belonging to 18 genera and eight families indicates that the most effective strategy for preserving genetic variation in species is to conserve as many populations as possible.
An ITS phylogeny of tribe Senecioneae (Asteraceae) and a new delimitation of Senecio L.
Two phylogenies provide new insights into evolutionary relationships in Senecioneae and a new, monophyletic, delimitation of Senecio are proposed, resulting in a first approximation of a comprehensive phylogeny for the tribe.
Diversity, rarity and the evolution and conservation of the Canary Islands endemic flora
To investigate geographical patterns of diversity within the endemic flora, distribution data from published sources together with other field observation and herbarium data were used to compile a data matrix and WORLDMAP was used to investigate patterns of en- demic diversity, range size rarity (a measure of endemicity), phy- logenetic diversity and threatened taxon richness.
Conservation implications of high genetic variation in two closely related and highly threatened species of Crambe (Brassicaceae) endemic to the island of Gran Canaria: C. tamadabensis and C. pritzelii
Data from 12 allozyme loci for two endemic Brassicaceae from Gran Canaria suggest that conservation efforts aimed at maintaining the existing genetic connectivity in each species and ex situ conservation of seeds are the best strategies to conserve their genetic diversity.
