Population genetic structure of an estuarine and a reef fish species exploited by Brazilian artisanal fishing

open access: yesScientia Marina, 2016
In this study, we used microsatellite markers to examine the genetic structures of Centropomus undecimalis (Bloch, 1792) and Epinephelus marginatus (Lowe, 1834) populations collected from artisanal fishing sites along a stretch of coastline in ...

Common snook fed in alternate and continuous regimens with diet supplemented with Bacillus subtilis probiotic. [PDF]

open access: yes, 2017
The objective of this work was to evaluate the addition of Bacillus subtilis probiotic to the feed of common snook (Centropomus undecimalis) fingerlings, in alternate and continuous regimens. Six hundred and sixty fish, with verage length of 5.90±0.88 cm

Precursor-mediated crystallization process in suspensions of hard spheres

open access: yes, 2010
We report on a large scale computer simulation study of crystal nucleation in hard spheres. Through a combined analysis of real and reciprocal space data, a picture of a two-step crystallization process is supported: First dense, amorphous clusters form ...

Field‐based evidence of impaired sperm quality associated with conventional farming in two passerine birds

open access: yesIbis, Volume 168, Issue 2, Page 504-519, April 2026.
The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,

Analysis of the Structure and Genesis of the June 23, 2016, Funing Tornado Based on 100‐Meter‐Scale Numerical Simulation

open access: yesMeteorological Applications, Volume 33, Issue 2, March/April 2026.
Structural characteristics of an EF4 tornado in Funing were reproduced through numerical simulation with a hectometer‐scale resolution. Results demonstrate that the tornado initiated in the mid‐ to upper‐levels, with the stretching term of the vorticity equation playing a dominant role throughout its development. ABSTRACT Tornadoes are characterized by

Partial Characterization of Digestive Proteases in the Common Snook Centropomus undecimalis

open access: yesInternational Journal of Biology, 2016
<p class="1Body">Common snook (<em>Centropomus undecimalis</em>) is a marine species with high aquaculture potential; although its digestive physiology is still unknown and knowledge of that could allow the development of a balanced feed for commercial culture of this fish. The objective of this study was to partially characterize the

Dietary resilience of coral reef fishes to habitat degradation

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

A new species of Acantholochus (Copepoda: Bomolochidae) parasitic on Centropomus undecimalis (Osteichthyes: Centropomidae) from the coastal zone of the State of Rio de Janeiro, Brazil

open access: yesMemorias do Instituto Oswaldo Cruz, 2003
A new species of Acantholochus Cressey, 1984 (Copepoda: Bomolochidae) parasitic on the gills of common snook, Centropomus undecimalis, from the coastal zone of the State of Rio de Janeiro, Brazil, is described and illustrated.
