Karyotypic diversity and evolution of Loricariidae (Pisces, Siluriformes)
Article Abstract:
The diversity and nucleolar organizing regions (NORs) macro-karyotypic evolution in four fish species are examined in relation to the evolution of the Loricariidae. The terminal location is the most frequent NOR phenotype observed in H. loricariformis whereas interstitial NORs are found in the remaining Harttia species.

Extreme polymorphism in a Y-linked sexually selected trait
Article Abstract:
The ways in which locus or loci controlling the male color polymorphism is linked to the Y-chromosome is demonstrated through pedigree analysis. The alternative male-mating strategies, sperm competition and other processes, which override female preferences, are discussed.

Deciphering the swordtail's tale: a molecular and evolutionary quest
Article Abstract:
The idea that morphological traits can evolve in response to mating preference and/or competition for mates is further studied. A molecular insight into the development of the swordtail and its history is put forth.
