Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

open access: yesJournal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Morphological and molecular evidence reveals a new species of Characidium from the Ucayali‐Urubamba Piedmont, Peru, and novel molecular clades are proposed within the genus

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...

A new South American darter (Crenuchidae: Characidium) from rivers draining the Northeastern Mata Atlantica Freshwater Ecoregion, Brazil: morphological and molecular evidence

open access: yesJournal of Fish Biology, EarlyView.
Abstract Characidium tupi, a new species from rivers draining the southern portion of the Northeastern Mata Atlantica Freshwater Ecoregion, is described. The new species can be distinguished from all congeners by its colour pattern, including 7–14 dark bars enlarged and more conspicuous on their ventralmost portion, resulting in a longitudinal series ...

Impact of monomer contamination of isopropanol during post‐rinsing on the accuracy of dental models fabricated by vat photopolymerization

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The aim of this study was to investigate the impact of an increasing level of monomer contamination of isopropanol (isopropyl alcohol [IPA]) during post‐rinsing on the dimensional stability of test samples produced by vat photopolymerization.

Influence of the Azores high on sea level pressure and wind, and on precipitation, in the Eastern Tropical Pacific Ocean [PDF]

open access: yes, 1966
ENGLISH: Intensification of the Azores high pressure cell in mid-year, with concomitant air flow from the Caribbean into the Pacific, is shown to be responsible for a secondary minimum of precipitation observed along the tropical Pacific coast of the ...

Minimally invasive osteosynthesis using a dynamic compression angle‐stable interlocking nail in feline transverse femoral fractures: an ex vivo study

open access: yesJournal of Small Animal Practice, EarlyView.
Objective To evaluate the effectiveness of interfragmentary compression in feline femoral transverse fractures treated with a dynamic compression angle‐stable interlocking nail implanted via minimally invasive nail osteosynthesis. Methods Thirty femurs from 15 feline cadavers were allocated into three groups according to fracture location (n = 10 per ...
