Perfect timing:Making the 'switch' from juvenile to adult(图)     Perfect timing  Making  switch  juvenile  adult       font style='font-size:12px;'> 2019/10/23
Very little is known about how the onset of puberty is controlled in humans, but an NSF-funded discovery of a new gene in the roundworm C. elegans could be the "missing link" that determines the juven...

Marine reserves—sections of the ocean where fishing is prohibited—promote coral reef sustainability by preventing overfishing and increasing fish abundance and diversity. But to be effective, they nee...
Calmodulin (CaM) is a major intracellular calcium receptor. There is abundant calmodulin (CaM) in the oocytes and eggs of B. germanica during vitellogenesis and early embryogenesis. The accumulation o...
The interactive effects of nutrient availability and ocean acidification on coral calcification were investigated using post-settlement juvenile corals of Acropora digitifera cultured in nutrient-suf...
The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus as...
Fish were fed to apparent satiation three times daily in an aquarium with automatic temperature control and circulated water. Growth performance, plasma biochemical parameters, hepatic morphology and ...
A 3×2 factorial experiment was conducted to determine the effects of dietary protein and lipid levels on the growth and body composition of juvenile far eastern catfish. Six diets were formulated to c...
New Sr-Nd-O isotopic data are reported for the early Triassic (early Indosinian) Weiya quartz syenite from eastern Central Tianshan, northwestern China, with the aim of documenting its possible source...
The relationship between the lordosis severity and swimming performance in sea bass juveniles was investigated. In total, 149 experimental animals 110-130 days old that ranged from 1.44 to 3.44 g (mea...
This study focuses on understanding the temporal variability in hydrological and thermal conditions in a small mountain stream and its potential implication for two life stages of Atlantic salmon (Sal...
We show that death by dissolution is an important size-dependent mortality factor for juvenile bivalves. Utilizing a new experimental design, we were able to replicate saturation states in sediments ...
Critical Load (CL) methodology is currently used throughout Europe to assess the risks of ecological damage due to sulphur and nitrogen emissions. Critical acid neutralising capacity (ANCCRIT) is used...
This preliminary feeding trial was conducted to study the effects of different dietary selenium (Se) levels on growth performance and toxicity in juvenile black seabream, Acanthopagrus schlegeli (Blee...
There has been a significant downward trend in the annual abundance (= spatfall) of 0-age eastern oysters (Crassostrea virginica) measured in the autumn since 1940 in the Maryland portion of Chesapeak...
In order to disentangle if and when resource supply and adult and young-of-the-year (0+) fish predation affect zooplankton dynamics during spring, we monitored zooplankton during three consecutive yea...
