Assumption 0 analysis: comparative phylogenetic studies in the age of complexity [PDF]

open access: yes, 2008
Darwin's panoramic view of biology encompassed two metaphors: the phylogenetic tree, pointing to relatively linear (and divergent) complexity, and the tangled bank, pointing to reticulated (and convergent) complexity.

Islands contribute disproportionately high amounts of evolutionary diversity in passerine birds [PDF]

open access: yes, 2015
Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major ...

Biogeography of the Greater Antillean mosses [PDF]

open access: yes, 1990
The distinctions between dispersal and vicariance are discussed and shown how they relate to geological history. Postulated theories on the tectonic origins and history of the Greater Antilles are reviewed, as well as possible climatic events that would ...

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Network analysis identifies weak and strong links in a metapopulation system [PDF]

open access: yes, 2008
The identification of key populations shaping the structure and connectivity of metapopulation systems is a major challenge in population ecology. The use of molecular markers in the theoretical framework of population genetics has allowed great advances
