The costs and benefits of multiple mating in a mostly monandrous wasp [PDF]

, 2015
Funding: NERC DTGThe taxonomically widespread nature of polyandry remains a puzzle. Much of the empirical work regarding the costs and benefits of multiple mating to females has, for obvious reasons, relied on species that are already highly polyandrous.

The low intestinal and hepatic toxicity of hydrolyzed fumonisin B1 correlates with its inability to alter the metabolism of sphingolipids [PDF]

, 2012
Fumonisins are mycotoxins frequently found as natural contaminants in maize, where they are produced by the plant pathogen Fusarium verticillioides. They are toxic to animals and exert their effects through mechanisms involving disruption of sphingolipid

Experimental culture of snook Centropomus undecimalis and chucumite Centropomus parallelus (Perciformes: Centropomidae) in artisanal earthen ponds

Ciencias Marinas, 2006
 The common snook, Centropomus undecimalis, and the locally called chucumite, Centropomus parallelus, occur naturally in the Gulf of Mexico. They are considered high value species and are regularly exploited in coastal fisheries, particularly in the ...

Contracaecum jorgei in common snooks in Brazil: new host, locality record and remarks on misidentifications of Contracaecum spp. in GenBank

Anais da Academia Brasileira de Ciências
Contracaecum jorgei was recently described as a new anisakid species from the Argentine wolffish Hoplias argentinensis. This study aimed to report a new host and locality for C. jorgei and highlight inconsistencies in some Contracaecum spp.

17α-Methyltestosterone implants accelerate spermatogenesis in common snook, Centropomus undecimalis, during first sexual maturation

Theriogenology, 2018
The common snook, Centropomus undecimalis, is an emerging species for intensive fish culture, however, some reproductive aspects of this species, especially the development of the testes and the action of androgen hormones on spermatogenesis have not been studied. The objective of this study was to evaluate the effects of 17α-methyltestosterone (MT) on

Nonequilibrium Temperature and Thermometry in Heat-Conducting Phi-4 Models

, 2008
We analyze temperature and thermometry for simple nonequilibrium heat-conducting models. We show in detail, for both two- and three-dimensional systems, that the ideal gas thermometer corresponds to the concept of a local instantaneous mechanical kinetic

Community ecology of metazoan parasites of the later juvenile common snook Centropomus undecimalis (Osteichthyes: Centropomidae) from the coastal zone of the state of Rio de Janeiro, Brazil

Brazilian Journal of Biology
Between April and December 2000, seventy-nine specimens of Centropomus undecimalis from Angra dos Reis, coastal zone of the State of Rio de Janeiro (23º01'S, 44º19'W), Brazil, were necropsied to study their infracommunities of metazoan parasites.

Does intensive feeding frequency affect growth performance of common snook Centropomus undecimalis (Bloch, 1792)?

Brazilian Journal of Biology, 2018
Salt water recirculation systems using automatic feeders are a new frontier for marine aquaculture. It is possible to decrease the vulnerability of the traditional fish farming in open systems and reduce wasteful feeding and discharge of effluents, as ...
