Kleinia neriifolia Haw. is an endemic species on the Canarian archipelago, this species is widespread in the coastal thicket of all the Canarian islands. In the present study, genetic diversity and population structure of K. neriifolia were investigated using chloroplast gene sequences and nuclear SSR (simple sequence repeat). The differentiation among island populations, the historical demogra...

The 14 species of Crambe L. sect. Dendrocrambe DC. (Brassicaceae) form a monophyletic group endemic to the Canary and Madeira archipelagos. Both parsimony and maximum likelihood analyses of sequence data from the two internal transcribed spacer regions of nuclear ribosomal DNA were used to estimate phylogenetic relationships within this section. These analyses support the monophyly of three maj...

The Canary Islands have been a focus for phylogeographic studies on the colonization and diversification of endemic angiosperm taxa. Based on phylogeographic patterns, both inter island colonization and adaptive radiation seem to be the driving forces for speciation in most taxa. Here, we investigated the diversification of Micromeria on the Canary Islands and Madeira at the inter- and infraspe...

The invasion of non-native plant species is one of the greatest threats to natural ecosystems, and oceanic islands are especially susceptible to this threat. Fire, as a disturbance factor, has been found to promote non-native species invasion and fire intensity is one of the variables determining the severity of invasions. This study was designed to determine the impact of non-native species in...

The sub-alpine zones of oceanic islands are unique and dynamic ecosystems with high levels endemism, making them particularly suitable model systems in which to investigate evolutionary biogeographic processes. flora the Canary Islands is restricted Tenerife La Palma. Its origins poorly understood. Echium wildpretii Hook.f. an iconic species subalpine these two islands, distinct subspecies reco...

Extreme geohazards (volcanic eruptions, earthquakes, landslides, and tsunamis) have the potential to inflict cascading effects whose associated risks are difficult predict prepare for. Thus, these events generally not taken into account in hazard assessment. Anticipating occurrence of such extreme is thus key if our life-styles remain safe sustainable. Volcanic islands often source complex succ...

[1] We present a high resolution 3 dimensional (3D) P wave velocity model for Tenerife Island, Canaries, covering the top of Teide volcano (3,718 m a.s.l.) down to around 8 km below sea level (b.s.l). The tomographic inversion is based on a large data set of travel times obtained from a 3D active seismic experiment using offshore shots (air guns) recorded at more than 100 onshore seismic statio...
