Prioritizing and making efficient conservation plans for threatened populations requires information at both evolutionary and ecological timescales. Nevertheless, few studies integrate multidisciplinary approaches, mainly because of the difficulty for conservationists to assess simultaneously the evolutionary and ecological status of populations. Here, we sought to demonstrate how combining gen...

In this paper we describe a simple approach using double peaks in chromatograms generated as artefacts in the vicinity of heterozygous indels, to identify the specific sequences present in individual strands of a given DNA fragment. This method is useful to assign bases in individuals that are heterozygous at multiple sites. In addition, the relative sizes of the double peaks help to determine ...

En el presente escrito se presenta la simulación del hábitat físico de un tramo río Lozoya, con finalidad estimar disponibilidad potencialmente utilizable (HPU) para especie Chondrostoma polylepis, así como determinar caudal que maximiza dicho HPU. Para tal efecto utilizó Sistema PHABSIM (Physical Habitat Simulation System), y identificó HPU es 1.5 m3/s estadio vida juvenil, 0.65 alevín, 4.00 a...

Scanning electron microscopy (SEM) has been widely used to describe interspecific differences in egg quality of teleost freshwater fish, but potential intraspecific are poorly studied. Eggs many rheophilic cyprinids covered with adhesive structures such as attaching villi facilitating attachment at substrates spawning grounds high currents. Recent findings indicate that the cyprinid common nase...
