Víctor Pacheco
Principal  Professor and Curator of Mammals, Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Peru.

My main interest is the systematics, morphology, biogeography, and conservation of Neotropical mammals. I am currently working on the systematic revision of the genus
Thomasomys  and phylogenetic analyses of the thomasomyine group of rodents, and the effect of forests fragmentation on the diversity of small mammals communities in montane habitats.

Besides that, other current projects deal with biodiversity of the dry forests in Tumbes, macrozonification and ecology of montane forests in Huanuco, assessment of endangered species in the rio Apurimac valley, zoonosis (leptospirosis, arbovirus, hantavirus and lyssavirus) and consulting on environmental issues. My undergraduate and postgraduate students work on systematics, biogeography, ecology and conservation of mammals, frogs and fishes.
