The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

The dynamic spore [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
Most bacteria can, at least to some degree, hunker down during periods of stress and wait for good times to return. No cells, however, do this as effectively as those Bacilli and Clostridia that form spores. Dormant cells produced by these bacteria can survive most environmental challenges found on earth and even a few in outer space and can remain ...

Phenomics and Genomics Reveal Adaptation of Virgibacillus dokdonensis Strain 21D to Its Origin of Isolation, the Seawater-Brine Interface of the Mediterranean Sea Deep Hypersaline Anoxic Basin Discovery

open access: yesFrontiers in Microbiology, 2019
The adaptation of sporeformers to extreme environmental conditions is frequently questioned due to their capacity to produce highly resistant endospores that are considered as resting contaminants, not representing populations adapted to the system.
