Project Details
Description
The detection of cryptic species complexes is essential to appropriately delimit lineages and estimate the real magnitude of biodiversity; however, few studies have been carried out on Neotropical spiders.
In this work we will investigate whether the orbicular spider Araneus bogotensis corresponds to a cryptic complex of species.
To do this, the mitochondrial COI and nuclear ITS2 locus of populations throughout their distribution in Colombia will be sequenced and phylogenetic trees, divergence times, haplotype networks and genetic distances will be estimated.
Morphological data (landmarks) will be obtained from the same specimens, with which geometric morphometry will be performed.
With all the data, the number of lineages that make up this complex of species will be determined and their historical demography, as well as their evolution, will be studied.

Commitments / Obligations
Have the sequences of the extensions mentioned in the description for all the sampled populations and also have obtained the homologous landmark points of the specimens.
There will be a poster or written report of these results that will be an input for the student's undergraduate thesis, who wants to continue with the project for this purpose.
