Mitotic karyotype of the tropical freshwater crayfish Procambarus (Austrocambarus) llamasi (Decapoda: Cambaridae)

open access: yesRevista de Biología Tropical, 2010
In Mexico, the biology of Procambarus has been more studied than the biology of other Cambarids because of its diversity and potential use in aquaculture. We determined the karyotype of the Mexican tropical freshwater crayfish Procambarus (Austrocambarus)

Trisomía parcial 4p por cromosoma 4 recombinante originado por inversión pericéntrica de origen paterno

open access: yesRevista Peruana de Investigación Materno Perinatal, 2015
La trisomía parcial 4p, suele originarse de translocaciones entre el cromosoma 4 y otros cromosomas no homólogos o por inversión pericéntrica del cromosoma 4, originando gametos anómalos entre el cromosoma normal y el invertido, obteniéndose un cromosoma

Chromosome‐scale reference genome of Pectocarya recurvata, the species with the smallest reported genome size in Boraginaceae

open access: yesApplications in Plant Sciences, Volume 13, Issue 3, May-June 2025.
Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.

Sex‐Specific Variation in Foraging Behavior is Related to Telomere Length in a Long‐Lived Seabird

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer

Meristic co‐evolution and genomic co‐localization of lateral line scales and vertebrae in Central American cichlid fishes

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...

Puerto Rican welfare queens and the semiotics of respectability: The language of race, class, and gender

open access: yesJournal of Sociolinguistics, Volume 28, Issue 3, Page 71-93, June 2024.
Abstract In this article, we explore how raciolinguistic parody functions in a society that hegemonically denies racial divisions. Through an analysis of Puerto Rican comedian Natalia Lugo's YouTube portrayals of her character, Francheska the Yal ‘welfare queen,’ we argue that covert racialization operates through a semiotics of respectability, whereby
