I CONGRESO LATINOAMERICANO DE MASTOZOOLOGIA
POSTER
Biodiversidad del ecosistema Andino.El ecosistema montañoso de los Andes ha jugado un papel importante en la evolución y diversificación de la biota Sudamericana. Sin embargo, es muy poco lo que aún conocemos sobre la riqueza y abundancia de sus especies animales y vegetales. El Grupo de Investigaciones de la Biodiversidad (GiB-IADIZA)preparó este póster que acerca al público en general la riqueza de los mamíferos de las tierras Andinas. Material para difusión institucional, educación, actividades docentes y divulgación al público. Se puede adquirir en MAGRAF, CCT (CRICYT,Mendoza).

Food habits and impact of rooting behaviour of the invasive wild boar, Sus scrofa, in a protected area of the Monte Desert, Argentina
The wild boar, Sus scrofa, was introduced in the central region of Argentina in the early 20th century. A small feral population invaded the western area of the Man and Biosphere Reserve of Ñacuñán, Argentina in the early 1980’s. The purpose of our study was to provide information about the diet of wild boars in the semiarid region of Argentina and assess their potential effect on vegetation through soil rooting. We analyzed 41 faecal samples and compared cover plant composition between rooted and non rooted soil. Our results showed that 95% of the diet consisted of different parts (leaves, stems, glumes, fruits, seeds, and bulbs) of 36 plant species, while arthropods and animal tissue represented only 5% of the diet. Two plant species (Sphaeralcea miniata and Pitraea cuneato-ovata) composed the bulk of the diet, representing almost 50% of the total items found in the faeces. Plant cover was significantly different between rooted and non rooted areas. Rooted areas were dominated by Pitraea cuneato-ovata, whereas the cover of Lycium sp was higher in non rooted areas. This is the first study addressing the ecology of the wild boar in a protected area of the Monte Desert biome of Argentina.

Phylogeography and genetic variation in the South American rodent Tympanoctomys barrerae (Rodentia: Octodontidae)
The red viscacha rat, Tympanoctomys barrerae, is an octodontid rodent endemic to the arid west-central and
southern regions of Argentina. It is solitary, lives in complex burrows built in soft soil, and occurs at low
population densities in patches associated with salt basins and sand dunes in lowland habitats of the Monte and
Patagonia deserts. The purpose of this study was to investigate the genetic structure and biogeography of this
desert specialist. To assess genetic variation an 800-base pair fragment of the mitochondrial control region was
sequenced for 60 individuals from 8 localities across the species’ range. Relationships among haplotypes were
inferred from phylogenetic analyses (maximum parsimony, Bayesian, and networks). Genetic structure and
demographic history were analyzed with descriptive statistics, mismatch distributions, neutrality tests (Tajima’s
and Fu’s), and analyses of molecular variance (AMOVAs). In total, 26 haplotypes were found, most restricted
to single populations. The presence of unshared haplotypes was consistent with low migration rates. Within the
distribution (between 29uS and 39uS) southern and northern populations showed higher genetic diversity values
than central populations. Populations of T. barrerae showed moderate to high genetic differentiation on the
basis of haplotypes of central populations. AMOVA analyses indicated a moderate level of geographic structure
for all populations. Low haplotype and nucleotide diversities in central populations suggest a possible
bottleneck associated with Pleistocene glaciations or volcanic activity in this part of the range of the viscacha
rat. Phylogeographic structure was moderate, and the analyses recovered 2 principal clades: A (with central and
a part of the southern distribution) and B (with northern and another part of the southern distribution). Most
populations were polyphyletic, indicating that they have not been isolated long enough to reach reciprocal
monophyly. Demographic analyses conducted for clades A and B suggest a recent history of population
expansion. (Agustina Ojeda, Journal of Mammalogy, 91(2):302–313, 2010)
