THE EVOLUTIONARY ENIGMA OF BONEFISHES (ALBULA SPP.): CRYPTIC SPECIES AND ANCIENT SEPARATIONS IN A GLOBALLY DISTRIBUTED SHOREFISH
TLDR
Despite multiple cases of sympatry, sister-taxa relationships inferred from mtDNA indicate that divergence in allopatry has been the predominant speciation mechanism in Albula, and stabilizing selection in the homogeneous habitat occupied by bonefishes could promote the retention of highly conserved morphology and ecology.
Elemental stoichiometry of Drosophila and their hosts
TLDR
Total body N and P contents were determined in seven species of wild-caught Drosophila, their natural hosts, and artificial diets routinely used to rear these flies in the laboratory, suggesting phosphorus demands during oogenesis are high.

DNA Barcodes and Insights into the Relationships and Systematics of Buckeye Butterflies (Nymphalidae: Nymphalinae: Junonia) from the Americas
TLDR
DNA barcodes, although failing to resolve all recognized species and subspecies level taxa of New World Junonia, can provide valuable tools for identifying the two major lineages, and when used in conjunction with morphological, ecological, behavioral and life history information can provide insights into the taxonomy and evolution of this difficult group.
Genetic variation, population structure, and phylogenetic relationships of Triatoma rubida and T. recurva (Hemiptera: Reduviidae: Triatominae) from the Sonoran Desert, insect vectors of the Chagas'
TLDR
Phylogenetic analyses of gene and amino acid sequences employing both Bayesian and parsimony methods showed that T. recurva clustered within the phyllosoma complex of Triatoma species from central and southern Mexico with high statistical support, and that it was closely related to T. longipennis.
Population genetics of the swimming crab Callinectes bellicosus (Brachyura: Portunidae) from the eastern Pacific Ocean
TLDR
Maximum-likelihood estimates of long-term effective population size obtained with the program FLUCTUATE, in addition to highly significant values obtained from neutrality tests and mismatch analysis, are consistent with a population expansion dating to the Pleistocene epoch.
Phylogenetic relationships of elopomorph fishes inferred from mitochondrial ribosomal DNA sequences.
The superorder Elopomorpha, a grouping which includes all teleost fishes that possess a specialized leptocephalous larva [true eels (Anguilliformes), gulpers and bobtail snipe eels
Genetic, ecological and morphological differences among populations of the cactophilic Drosophila mojavensis from southwestern USA and northwestern Mexico, with descriptions of two new subspecies
TLDR
Evidence from studies on population genetics, ecology and behaviour that supports the subspecies assignments in D. mojavensis is reviewed, and descriptions of D. m.
Identification, structural analysis and function of hyaluronan in developing fish larvae (leptocephali).
TLDR
In addition to its presumed role in maintaining the structural integrity and hydration of the gelatinous body of the leptocephalus, HA is postulated to function as a storage polysaccharide in those species in which it is the predominant GAG.
