▪ Abstract Since the delineation of 12 bacterial phyla by comparative phylogenetic analyses
of 16S ribosomal RNA in 1987 knowledge of microbial diversity has expanded dramatically …

▪ Abstract The eutrophication of many ecosystems in recent decades has led to an increased
interest in the ecology of nitrogen transformation. Chemolitho-autotrophic ammonia …

In spite of technical advances that have provided increases in orders of magnitude in
sequencing coverage, microbial ecologists still grapple with how to interpret the genetic …

John Dupré explores recent revolutionary developments in biology and considers their
relevance for our understanding of human nature and human society. Epigenetics and …

To help advance the species definition for prokaryotes, we have compared the gene content
of 70 closely related and fully sequenced bacterial genomes to identify whether species …

Coral reefs are the most biodiverse of all marine ecosystems; however, very little is known
about prokaryotic diversity in these systems. To address this issue, we sequenced over 1000 …

The species concept is a recurrent controversial issue that preoccupies philosophers as well
as biologists of all disciplines. Prokaryotic species concept has its own history and results …

Vibrios are ubiquitous and abundant in the aquatic environment. A high abundance of
vibrios is also detected in tissues and/or organs of various marine algae and animals, eg …

The diversity of bacteria and archaea associating on the surface and interior of maize roots
(Zea mays L.) was investigated. A bacterial 16S rDNA primer was designed to amplify …

Accumulating prokaryotic gene and genome sequences reveal that the exchange of genetic
information through both homology-dependent recombination and horizontal (lateral) gene …
