Aim: We conduct a biogeographical assessment of orchids in a global biodiversity hotspot to explore their distribution and occurrences of local hotspots while identifying geographic attributes underpinning diversity ...

Hotspots are generated by partial melting due to hot plumes rising within the Earth's mantle, and when tectonic plates move relative to the plume source, hotspot tracks form. Off South America, the oceanic Nazca Plate hosts ...

Tropical reforestation is a significant component of global environmental change that is far less understood than tropical deforestation, despite having apparently increased widely in scale during recent decades. The ...

We report here the first detailed 2D tomographic image of the crust and upper mantle structure of a Cretaceous seamount that formed during the interaction of the Pacific plate and the Louisville hotspot. Results show ...

Any conservation strategy must deal with the uncertainty caused by anthropogenic climate change. In order to forecast such changes, the climate change velocity approach has been used to measure ecosystem exposure to this ...

The Brasiliensis subcomplex is a monophyletic group formed by the species Triatoma brasiliensis brasiliensis, T. b. macromelasoma, T. juazeirensis, T. melanica, and T. sherlocki. However, using cytogenetic data and ...

More than 50% of the Mexican flora is represented by 11,001 species of endemic vascular plants. These high levels of endemisms should be a primal criterion for the recognition of areas for conservation. However, it is ...

Dispersal and in situ speciation are seen as the main mechanisms behind the accumulation of species in an area. Biodiversity hotspots are often composed of a particular vegetation type that occupies a discrete geographical ...

The main goal of using global biodiversity hotspots for conservation purposes is to protect taxa with small geographic ranges because these are highly vulnerable to extinction. However, the extent to what different hotspots ...
