Seasonal Changes of Fish Assemblages in a Subtropical Lagoon in the SE Gulf of California

open access: yesThe Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The composition and seasonal changes of the fish assemblage in a coastal lagoon system in southeastern Gulf of California were assessed from December 2001 to July 2005. A total of 20,877 organisms belonging to 191 species and 47 families were analyzed. We determined that almost all the species inhabiting the system were found; however some rare species

Evolutionary patterns of DNA base composition at polymorphic sites highlight the role of the environment in shaping barley and rice genomes

open access: yesThe Plant Genome, Volume 17, Issue 2, June 2024.
Abstract Insights into changes in genome base composition underlying crop domestication can be gained by using comparative genomics. With this approach, previous studies have reported that crop genomes during domestication accumulate more nucleotides adenine (A) and thymine (T) (termed as [AT]‐increase) across polymorphic sites.
