Os cromossomos sexuais como fonte geradora de diferenciação genética. O gênero Pyrrhulina (Characiformes, Lebiasinidae) como modelo
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosBiotecnologia - Biotec, 2021-11-11)
Allopatric processes are generally considered among the main causes of the striking
Neotropical biodiversity. However, the role of chromosomal rearrangements and neo-sex
chromosomes in genetic diversity and speciation ...
Pre- and postcopulatory traits of Salvator male lizards in allopatry and sympatry
(Hindawi Limited, 2016-03)
The reproductive traits of males are under influence of sexual pressures before and after copulation. The strength of sexual selection varies across populations because they undergo varying competition for mating opportunities. ...
Ecological specialization and niche overlap of subterranean rodents inferred from DNA metabarcoding diet analysis
(Wiley-Blackwell, 2020-07-30)
Knowledge of how animal species use food resources available in the environment can increase our understanding of many ecological processes. However, obtaining this information using traditional methods is difficult for ...
Assessing biodiversity within the range of Heleobia chimbaensis (Caenogastropoda: Cochliopidae) on the Atacama Desert coast
(Taylor and Francis, 2020)
Heleobiais the most specious genus in the family Cochliopidae, in which many species are morphologically similar. Here we used morphological, microstructural and phylogenetic criteria to investigate species delimitation ...
Thermal biology of Liolaemus lizards from the high Andes: Being efficient despite adversity
(Pergamon-elsevier Science Ltd, 2013-01-03)
We studied the efficiency of thermoregulation in four high elevation Liolaemus species in the Andes of Salta, Argentina; L. irregularis, L. multicolor, L. albiceps and L. yanalcu. One of the species, L. irregularis, shows ...
Divergence and evolution of reproductive barriers among three allopatric populations of Rhagoletis cingulata across eastern North America and México
(Wiley, 2015-09)
Geography is often a key factor facilitating population divergence and speciation. In this regard, the geographic distributions of flies in the genus Rhagoletis (Diptera: Tephritidae) in temperate North America have been ...
Historical allopatry and secondary contact or primary intergradation in the Puerto Rican crested anole, Anolis cristatellus, on Vieques Island in the CaribbeanAlopatría histórica y contacto secundario o intergradación primaria en el ánulo coronado puertorriqueño, Anolis cristatellus, en la isla de Vieques en el Caribe

Morfologia funcional das estruturas alimentares de duas espécies simpátricas do gênero Aegla (crustacea, anomura, aeglidae).
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2017-10-20)
The Aeglidae family has an important participation in the decomposition of organic matter in streams of first and second order. This dissertation aims to analyze morphological characters in sympatric populations of Aegla ...
