The Quintessential Naturalist: Honoring the Life and Legacy of Oliver P. Pearson (2007)

Kelt, Douglas A, Lessa, Enrique P., Salazar-Bravo, Jorge, Patton, James L.

Oliver P. Pearson's studies on mammalian biology remain standard reading for ecologists, physiologists, taxonomists, and biogeographers. Reflecting this, the papers gathered here continue to expand...

Adaptive Evolution of the Insulin Gene in Caviomorph Rodents (2005)

Opazo, Juan C., Palma, R. Eduardo, Melo, Francisco, Lessa, Enrique P.

Insulin is a conservative molecule among mammals, maintaining both its structure and function. Rodents that belong to the Suborder Hystricognathi represent an exception, having a very divergent...

GENETIC AND GEOGRAPHIC DIFFERENTIATION IN THE RIO NEGRO TUCO-TUCO (CTENOMYS RIONEGRENSIS): INFERRING THE ROLES OF MIGRATION AND DRIFT FROM MULTIPLE GENETIC MARKERS (2003)

Gabriela Wlasiuk, John Carlos Garza, Enrique P. Lessa

Among tuco-tucos, Ctenomys rionegrensis is especially amenable to the study of the forces driving population differentiation because of the restricted geographic range it occupies in Uruguay. Within...

Molecular Evolution of Aldolase A Pseudogenes in Mice: Multiple Origins, Subsequent Duplications, and Heterogeneity of Evolutionary Rates (2001)

Cortinas, María Noel, Lessa, Enrique P.

The Aldolase multigene family comprises three functional genes (A, B, and C) with tissue-specific expression regulated during ontogeny. DGGE analysis and nucleotide sequencing reveal a family of...

Recurrent Amplifications and Deletions of Satellite DNA Accompanied Chromosomal Diversification in South American Tuco-tucos (Genus Ctenomys, Rodentia: Octodontidae): A Phylogenetic Approach (2001)

Slamovits, Claudio H., Cook, Joseph A., Lessa, Enrique P., Susana Rossi, M.

We investigated the relationship between satellite copy number and chromosomal evolution in tuco-tucos (genus Ctenomys), a karyotypically diverse clade of rodents. To explore phylogenetic...

Molecular Phylogeny of Tuco-Tucos, Genus Ctenomys (Rodentia: Octodontidae): Evaluation of the mendocinus Species Group and the Evolution of Asymmetric Sperm (1999)

Cook, Joseph A., D'Elía, Guillermo, Lessa, Enrique P.

The phylogenetic relationships among 23 individuals representing 14 species of underground hystricognath rodents of the genus Ctenomys were studied by analyzing variation of complete cytochrome b...

Multidimensional Analysis of Geographic Genetic Structure (1990)

Lessa, Enrique P.

Multilocus data are an important source of information on genetic variation within and among natural populations. Hierarchical techniques are used widely for examining multilocus data. However, the...

Genetic footprints of demographic expansion in North America, but not Amazonia, during the Late Quaternary

Lessa, Enrique P., Cook, Joseph A., Patton, James L.

The biotic consequences of climate change have attracted considerable attention. In particular, the “refugial debate” centers on the possible retraction of habitats to limited areas that may have...
