Color polymorphism in Leptodactylus fuscus (Anura, Leptodactylidae): A defensive strategy against predators?
(2010-06-10)
Color patterns are strongly related to defensive strategies in anurans. Some anurans present more than one morphotype. Leptodactylus fuscus, for example, present two morphotypes (with and without vertebral white line). The ...

The evolution of behavioural systems: a study of grooming in rodents
(Brill Academic Publishers, 2013-01-01)
In the present paper we focus on the study of complex behavioural systems, within an explicit phylogenetic framework. We reconstruct the phylogeny of rodents using grooming sequences from 12 terminals. Using a method derived ...
Phylogenetic analysis of the evolutionary correlation using likelihood
Many evolutionary processes can lead to a change in the correlation between continuous characters over time or on different branches of a phylogenetic tree. Shifts in genetic or functional constraint, in the selective ...
Development and evolution of the gynoecium in Myrteae (Myrtaceae)
(Csiro Publishing, 2014-01-01)
Characters of the gynoecium are considered potentially significant for the systematics of Myrtaceae. However, only two such characters - ovule number and placentation - have been addressed from an evolutionary perspective. ...
Molecular phylogenetics and character evolution of the ""sacaca"" clade: Novel relationships of Croton section Cleodora (Euphorbiaceae)
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Phylogenetic relationships of Croton section Cleodora (Klotzsch) Baill. were evaluated using the nuclear ribosomal ITS and the chloroplast trnl-F and trnH-psbA regions. Our results show a strongly supported clade containing ...
Occurrence of biflagellate spermatozoa in Cetopsidae, Aspredinidae, and Nematogenyidae (Teleostei : Ostariophysi : Siluriformes)
(Springer, 2006-08-01)
In the present study spermiogenesis was investigated in Cetopsis coecutiens (Cetopsidae), and Bunocephalus amazonicus (Aspredinidae), while spermatozoa ultrastructure was investigated in C. coecutiens, B. amazonicus, and ...
