Understanding how populations and species evolve in response to their environment is a key objective of population and evolutionary genetics. Extremes are useful to understand both where current models break down and to build new ones. Coalescent …
At first look, the harsh physical conditions of the Andes should impose serious physiological constraints on hummingbirds, but instead, they have a wide distribution and are abundant at high altitudes. Several studies suggest highland species are …
Chemosensation detects environmental chemical cues and mediates many behaviors directly related to fitness (e.g. finding food, mates). Mammals have a secondary chemosensory system known as vomerolfaction that is primarily attributed to detecting …
Vicariance and dispersal are the main hypotheses used to explain the distribution and diversification of taxa on both continents and islands. Research on the origin and diversification of island biotas is particularly appealing because these have …
Una población de 134 líneas autógamas recombinantes derivadas del cruce Fanny x Oryzica Llanos 5 fue evaluada cuantitativamente para resistencia al virus de hoja blanca en invernadero. La segregación de 74 marcadores RFLP provenientes del mapa …
