Weighted parsimony phylogeny of the family Characidae (Teleostei: Characiformes) [PDF]

Cladistics, 2009
AbstractThe family Characidae, including more than 1000 species, lacks a phylogenetic diagnosis, with many of its genera currently considered as incertae sedis. The aims of the present study are to propose a phylogenetic diagnosis and to assess higher‐level relationships of and within Characidae. In this regard, 360 morphological characters are studied

The dynamics of parental care of Copeina arnoldi (pisces, characidae)

Behavioral Biology, 1976
The parental behavior of 10 isolated male Copeina arnoldi with single spawns was monitored throughout the parental cycle. Parental splashing frequency decreased daily after spawning. Daily mean splashing frequencies observed ranged from 38.5 to 0.2 splashes per hour. No diurnal cycle of parental splashing could be discerned. Bouts of parental splashing
