Ecologia de Tropidurus torquatus (Squamata: Tropiduridae) no bioma Pampa, extremo sul do Brasil
(Universidade Federal de Santa Maria, 2009-04-03)
Lizards are considered model organism in ecology, allowing the understanding of patterns and relations between organisms and environment. Tropidurus torquatus is a species with a broad distribution, with populations in ...

História evolutiva dos elementos homo1 e howilli2 de espécies de drosofilídeos neotropicais
(Universidade Federal de Santa Maria, 2013-03-01)
Transposable elements (TEs) are DNA fragments that can move within and between genomes causing great impact on the evolution of organisms. The hAT superfamily belongs to class II, subclass I of TEs and despite having ...
Macroinvertebrados associados às folhas em decomposição de riachos neotropicais: influência da qualidade química, variedade de espécies vegetais, biomassa de fungos e tempo de exposição
(Universidade Federal de Santa Maria, 2013-03-08)
In low-order freshwater ecosystems, macroinvertebrates have an important role in nutrient cycling, as they participate in the shredding of detritus, which are the main energy source for the trophic chain in these systems. ...

DNA barcode de drosofilídeos micófagos pertencentes aos gêneros Hirtodrosophila, Mycodrosophila e Zygothrica
(Universidade Federal de Santa Maria, 2011-02-28)
The biodiversity that exists in our planet is huge and far from being known. Most of the times
the techniques that are used in species identification are based in the morphology of the
specimens, and the description is ...
Variabilidade da atividade do elemento de transposição mariner em populações naturais de Drosophila simulans
(Universidade Federal de Santa Maria, 2012-02-24)
Transposition elements (TEs) are DNA sequences with the ability to move from one
chromosome region to another. These elements have different mechanisms of transposition
and diversity in their sequences, giving them wide ...
Aegla platensis (Schimit, 1942): um complexo de espécies? Evidências a partir do gene mitocondrial COI
(Universidade Federal de Santa Maria, 2011-02-22)
Aeglid crabs have attracted researchers because they represent the only
anomuran family entirely restricted to continental waters, besides being endemic to
the tropical and temperate regions of South America, occurring ...
Uso do habitat por pequenos mamíferos em um mosaico de floresta - campo no extremo sul da Floresta Atlântica
(Universidade Federal de Santa Maria, 2013-02-25)
The macro and microhabitat use by small-mammal was investigated in an Atlantic Forest- Pampa mosaic. A grid with 88 traps was used, being 27 installed in the understory every two traps placed on the ground, which were 70 ...
Diversidade e distribuição espacial de comunidades de macroinvertebrados aquáticos em áreas de cultivo de arroz e banhados no extremo sul do Brasil
(Universidade Federal de Santa Maria, 2013-02-25)
The role of rice fields in representing alternative refugees for wetland-expelled
macroinvertebrates, in various scales, was assessed in southern Brazil. It is expected that rice
fields sustain a representative version, ...
