Silversides of the genus Labidesthes (Atheriniformes: Atherinopsidae)
Zootaxa, 2015The two species of Labidesthes, L. sicculus and L. vanhyningi, are herein redescribed. Labidesthes sicculus is separated from L. vanhyningi by the presence of an anterolateral process of the post temporal that is longer than it is wide (versus wider than long), a ratio of thoracic length to abdominal length greater than two (versus less than two), and ...

The complete mitochondrial genome ofOdontesthessp. (Atheriniforms, Atherinopsidae)
Mitochondrial DNA, 2014In this study, the complete mitochondrial genome of Odontesthes sp. has been studied first. The genome is 16,528 bp in length and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and 1 putative control region. The mitochondrial genome of Odontesthes sp.

Abstract The shortfin silverside Chirostoma humboldtianum has been considered for culture in Mexico, but success has been limited by a poor knowledge of its early development. First synthesis of the early development of the shortfin silverside is presented to determine conditions suitable for rearing.

Copeia, 2003
Abstract Population structure of the California grunion, Leuresthes tenuis, was asssessed by examining patterns of allozymic variation. Six specimens from each of four southern California locations (Goleta, Malibu, San Pedro, and Imperial Beach) were examined electrophoretically for the gene products of 55 presumptive loci; nine loci were found to be ...

Copeia, 2006
Abstract Vertebral number is used frequently as a diagnostic species character in fishes, but it varies not only among but also within species. Much of the variation in vertebral number is associated with geographic gradients such as latitude, and it likely reflects both environmental and genetic influences on phenotype. Hence, comparison of intra- and
