Novel microsatellite markers suggest significant genetic isolation in the Eastern Pacific sponge Aplysina gerardogreeni.

Background: The Eastern Tropical Pacific (ETP) harbors a great diversity of Porifera. In particular, the Aplysina genus has acquired biotechnological and pharmacological importance. Nevertheless, the ecological aspects of their species and populations have been poorly studied.

Regional variation in multiple paternity in the brown smooth-hound shark Mustelus henlei from the northeastern Pacific.

Multiple paternity (MP) in the brown smooth-hound shark (Mustelus henlei) was assessed in 15 litters (15 mothers and 97 embryos) collected in the northern Gulf of California of which 86.7% were sired by more than one male (i.e.

Possible female philopatry of the smooth hammerhead shark Sphyrna zygaena revealed by genetic structure patterns.

We assessed the spatial pattern of genetic structure of smooth hammerhead shark Sphyrna zygaena in 10 localities from the Northern Mexican Pacific. A total of 35 haplotypes were identified in 129 sequences of the mtDNA control region. The results showed slight but significant genetic structure among localities (Φ = 0.

Complete mitochondrial genome of the Devil Ray, (Lloyd, 1908) (Myliobatiformes: Myliobatidae).

The Devil Ray () is a species with global distribution and is an important species in conservation terms, here we present its complete mitochondrial genome assembled with Illumina sequencing data. The circular genome was 17,610 bp in length, and consists of 13 protein-coding, two ribosomal RNAs (rRNAs), and 22 transfer RNA (tRNA) genes. Base composition is 30.

Complete mitochondrial genome of the Chihuil sea catfish (Siluriformes: Ariidae).

The chihuil sea catfish () is endemic of the Eastern Pacific and is a species of fishery importance in the Mexican Pacific. The complete mitochondrial genome of has been assembled from Illumina sequencing data. The circular genome was 16,714 bp in lengh, and consist of 13 protein-coding, two ribosomal RNAs (rRNAs), and 22 transfer RNA (tRNA) genes.

Complete mitochondrial genome of Cominate sea catfish (Siluriformes: Ariidae).

The mitochondrion genome of was assembled from Illumina short reads, and consisted of 16,714 base pairs, with 13 protein-coding, two ribosomal RNAs (rRNAs), and 22 transfer RNA (tRNA) genes. Base composition is 30.7% A, 26.

Mitochondrial Genetic Structure and Matrilineal Origin of White Sharks, Carcharodon carcharias, in the Northeastern Pacific: Implications for Their Conservation.

White sharks (Carcharodon carcharias, WS henceforth) are globally and regionally threatened. Understanding their patterns of abundance and connectivity, as they relate to habitat use, is central for delineating conservation units and identifying priority areas for conservation. We analyzed mitochondrial data to test the congruence between patterns of genetic connectivity and of individual movements in the Northeastern Pacific (NEP) and to trace the matrilineal origin of immature WS from coastal California and Baja California to adult aggregation areas.

Testing the genetic predictions of a biogeographical model in a dominant endemic Eastern Pacific coral (Porites panamensis) using a genetic seascape approach.

The coral fauna of the Eastern Tropical Pacific (ETP) is depauperate and peripheral; hence, it has drawn attention to the factors allowing its survival. Here, we use a genetic seascape approach and ecological niche modeling to unravel the environmental factors correlating with the genetic variation of Porites panamensis, a hermatypic coral endemic to the ETP. Specifically, we test if levels of diversity and connectivity are higher among abundant than among depauperate populations, as expected by a geographically relaxed version of the Abundant Center Hypothesis (rel-ACH).
