Similarities among ectoparasite fauna of sigmodontine rodents: phylogenetic and geographical influences
(Cambridge University Press, 2012-11-01)
Phylogenetic and geographical overlaps in host distributions influence the compositional similarity of ectoparasite fauna in a host-parasite system. In these systems, hosts that are more closely related (phylogenetically) ...

Sensibilidad de Elmidae (Insecta: Coleoptera) a la perturbación del hábitat y la calidad fisicoquímica del agua en ambientes lóticos de los Andes colombianosSensitivity of Elmidae (Insecta: Coleoptera) to habitat disturbance and physicochemical water quality in lotic environments of the colombian Andes
(Universidad de Costa Rica, 2020-06)
Introducción: Los élmidos son organismos acuáticos frecuentemente asociados con aguas corrientes, limpias y bien oxigenadas. Sin embargo, algunos géneros de esta familia también se encuentran en aguas moderadamente ...
Efeitos espaciais e ambientais sobre a distribuição e diversidade beta de peixes em riachos da bacia do Alto Rio Paraná, Brasil
(Universidade Federal de Mato GrossoBrasilInstituto de Biociências (IB)UFMT CUC - CuiabáPrograma de Pós-Graduação em Ecologia e Conservação da Biodiversidade, 2014-05-02)
We aimed to evaluate whether variation in stream fish community composition is better explained by environmental factors, spatial factors or by both, over local and regional scales. We also analyzed whether fish beta ...
Ecomorfologia trófica de peixes bioindicadores de riachos submetidos a diferentes graus de antropização
(Universidade Tecnológica Federal do ParanáLondrinaBrasilPrograma de Pós-Graduação em Engenharia AmbientalUTFPR, 2020-02-27)
Aquatic ecosystems have suffered recurrent environmental impacts that imply changes in biota, with repercussions for their conservation. In this context, the present study evaluates the variations in ecomorphological and ...
Geographical variation in head shape of a Neotropical group of toads: the role of physical environment and relatedness
(Wiley-Blackwell, 2017-02-01)
In this study we review the morphological variation within the Rhinella crucifer species group using geometric morphometrics. We sampled 270 specimens from 78 localities comprising all genetic units delimited for the group. ...
Evaluating microevolutionary models for the early settlement of the New World: The importance of recurrent gene flow with Asia
(Wiley-liss, Div John Wiley & Sons Inc, 2011-12)
Different scenarios attempting to describe the initial phases of the human dispersal from Asia into the New World have been proposed during the last two decades. However, some aspects concerning the population affinities ...
