Dinâmica espacial, migração e preferência de micro-hábitat de Aegla longirostri bond-buckup e buckup, 1994 (crustacea, anomura, aeglidae)
(Universidade Federal de Santa Maria, 2014-02-25)
Understanding the population dynamic processes is fundamental to access its viability (health). Great part of these processes is closely related to the organism densities in a studied population. These data can reveal how ...
A influência de gradientes ambientais e da radiação ultravioleta sobre comunidades de anuros do extremo sul da Mata Atlântica
(Universidade Federal de Santa Maria, 2017-02-16)
Amphibians are among the most threatened vertebrate groups on the planet, mainly due

evaluated how the modification of the ...
Fatores determinantes do tamanho corporal, forma do crânio e uso do espaço em mamíferos sul-americanos (Laurasiatheria), com ênfase em felídeos
(Universidade Federal de Santa Maria, 2017-04-26)
The characteristics of animals show similarities or differences according to the environment in which they are inserted and result in selection of characters that determine them, differentiating them phenotypically. ...
Alimentação e desenvolvimento de macroinvertebrados límnicos frente à variação na qualidade do recurso e temperatura do ambiente
(Universidade Federal de Santa Maria, 2018-03-09)
The aquatic ecosystems exhibit a diversity of biotic and abiotic characteristics, which together determine their functioning. In these environments, the macroinvertebrates community depend on the conditions found in the ...
Variação latitudinal nos limites de tolerância e plasticidade térmica em anfíbios em um cenário de mudanças climáticas: efeito dos micro-habitats, sazonalidade e filogenia
(Universidade Federal de Santa Maria, 2018-02-23)
Under the current scenario of climate change, the inclusion of precise knowledge of individually-based thermal exposures estimates with physiological traits, allows to formulate objective metrics to assess present ectotherm ...
Variação ecogeográfica e funcional do crânio de Tayassuidae (Mammalia: Artiodactyla)
(Universidade Federal de Santa Maria, 2018-02-22)
Understanding the determining mechanisms and functional roles of phenotypic variation have been a central topic of ecogeography and evolution. Peccaries are excellent models for testing ecogeographical and functional ...
