Article
Full-text available
Neospora caninum, Toxoplasma gondii and Hammondia spp. are coccidian parasites similar in morphology. Molecular techniques are necessary to detect parasite DNA isolated from stool samples in wild canids because they were reported as definitive hosts of N. caninum life cycle. The objective of this study was to develop a highly sensitive and accurate...
Article
Felids are among the species most threatened by habitat fragmentation resulting from land-use change. In the Uruguayan Savanna ecoregion, about 30% of natural habitats have been lost, large felids have been eradicated from most of the region, and the impact of anthropogenic threats over the smaller species that remain is unknown. To develop managem...
Chapter
Uruguay is located in the Neotropical region in a transitional zone with assemblage of diverse ecotypes being the austral limit of the distribution for several species of tropical plants and animals. The aim of this chapter is to provide a review of the Uruguayan ungulate species knowledge: the current distribution patterns, ecology, and evolutiona...

Using non–invasive genetic techniques to assist in maned wolf conservation in a remnant fragment of the Brazilian Cerrado. The maned wolf is a South American canid considered a keystone species of the Cerrado. We performed a genetic assessment of maned wolves that inhabit a small remnant fragment of the Cerrado in Brazil. We collected 84 fecal samp...
Article

The maned wolf Chrysocyon brachyurus is the largest South American canid and categorized as Near Threatened on the IUCN Red List. The major threat to conservation efforts is the drastic reduction of suitable habitat for the species. A large portion of its range has been converted into farm and ranch lands as well as urban areas. To better understan...
Article
Strategies to evaluate and monitoring elusive mammal species require the development of genetic techniques and their application to unambiguous biological material for ecological and genetic studies. In order to assess cytochrome c oxidase subunit II gene inter- and intraspecific variation, we compared sequences from different Neotropical canids an...
Article
Taxonomic identity and genetic variation of three bone samples from a late Holocene earth mound in the eastern Uruguayan lowlands were analyzed. Samples were initially identified by morphology as being from pampas deer (Ozotoceros bezoarticus), a middle-sized cervid that occupies open environments forming herds of up to 50 animals. Prehistoric huma...
Article
Full-text available
We describe a fast and reliable genetic method for sexing Neotropical canids by high resolution melting analysis of amplicons obtained by real time polymerase chain reaction. We used a primer set that amplifies a 195 bp fragment of the ZFX and ZFY genes to determine the sex of pampas fox (Pseudalopex gymnocercus), crab eating fox (Cerdocyon thous),...
Article
The Andean bear (Tremarctos ornatus) is found throughout the Andes Mountains from Venezuela to Bolivia. However, little is known about its distribution and range in southern areas, including Argentina. Our objective was to develop a genetic marker to identify this species by analysis of non-invasive samples (i.e., hair or feces). We designed a prim...
Article
Full-text available
Ctenomys pearsoni (Pearson's tuco-tuco) is a subterranean rodent native to Uruguay. We tested the amplification pattern of 12 microsatellite loci, designed for C. sociabilis and C. haigi in a C. pearsoni population. DNA extractions were made from hair samples, and PCR amplification products were run on an ABI 3100 microcapillary gel. Eight loci wer...

Project
“Tell Science” is a ongoing Uruguayan educational project that aims to promote science education at early stages (7-11 years old), facilitating current scientific information of limited access to public schools, in a format suitable for children (FB_Los niños que cuentan ciencia). Our project is in cooperation with the National Council for Elementary School (CEIP-ANEP) and it is a long-term three-pillar program based on direct experiences, generation of educational resources, and its popularization. We mainly work on reverting children fear and disgust perceptions toward different organisms, as well as demystifying biology misconceptions, by means of scientific information and experiences. This can transform the negative image of unpopular organisms, endeavouring to make an important contribution to environmental education.
