Continuous tooth replacement: what can teleost fish teach us?
ABSTRACT Most tooth‐bearing non‐mammalian vertebrates have the capacity to replace their teeth throughout life. This capacity was lost in mammals, which replace their teeth only once at most. Not surprisingly, continuous tooth replacement has attracted much attention. Classical morphological studies (e.g.

To date, little attention has been devoted to possible complementary effects of multiple forms of public information similar information on the foraging behaviour of predators. In order to examine how predators may incorporate multiple information sources, we conducted a series of predator attraction trials in the Lower Aripo River, Trinidad.

Assessing fish diversity in abandoned mining ponds in Madre de Dios, Peru, using environmental DNA
We surveyed four lentic systems in Madre de Dios, Peru: two abandoned mining ponds created by ASGM and two unmined oxbow lakes as a reference to assess fish recolonization. We compared two alternative eDNA processing methods and contrasted our results with historic data from traditional biodiversity monitoring. Our results indicate that eDNA could be a

To date, seven species of Characithecium Mendonza-Franco, Reina and Torchin, 2009 (Monogenea, Dactylogyridae) are valid, parasitizing mainly fishes of the family Characidae (Characiformes) in the Neotropical region. During a parasitological study of fishes in the Batateiras River and Carás stream, Ceará state, Brazil, two species of Characithecium were
