Mountain biodiversity and elevational gradients [PDF]

open access: yesFrontiers of Biogeography, 2021
Mountains are excellent systems for studying species responses to changing conditions because climatic conditions and related productivity measures change rapidly over short distances (Korner 2007).  Mountains also often have high biodiversity and high levels of endemism (Hoorn et al. 2018, Rahbek et al.

Why mountains matter for biodiversity [PDF]

open access: yesJournal of Biogeography, 2019
Mountains are arguably Earth’s most striking features. They play a major role in determining global and regional climates, are the source of most rivers, act as cradles, barriers and bridges for species, and are crucial for the survival and sustainability of many human societies. The complexity of mountains is tightly associated with high biodiversity,

Mountain biodiversity in Brazil [PDF]

open access: yesRevista Brasileira de Botânica, 2007
The high species richness and diversity found in tropical montane habitats are often related to: 1) an effect of climatic and geological history on biotic evolution; 2) the various environmental impacts on species adaptation mechanisms; and 3) the continuous dispersal of fauna and flora in time.
