Tropical South America Diatom Database: a tool for studying the macroecology of microorganisms
(Taylor and Francis, 2022-06-28)
Determining the mechanisms of community assembly forms the foundation of biogeography and community ecology. Studies of the biodiversity and distribution of Neotropical macro-organisms have revealed the ...
Nile tilapia broodfish fed high‐protein diets: Digestive enzymes in eggs and larvae
(Wiley, 2019-05-12)
The aim of this study was to assess the activity of gastric, pancreatic and intestinal digestive enzymes during the embryonic and larval development of Nile tilapia (Oreochromis niloticus) GIFT strain ...
Effects of the application of a moderate alternate wetting and drying technique on the performance of different European varieties in Northern Italy rice system
(Elsevier, 2021-07-03)
Alternate wetting and drying (AWD) technique has been developed and evaluated on rice (Oryza sativa) systems in several countries worldwide for increasing water use efficiency and reducing negative ...
Taurine supplementation in high-soy diets affects fillet quality of European sea bass (Dicentrarchus labrax)
(Elsevier, 2019-11-01)
This study evaluated the effects of taurine supplementation to diets containing a high dietary inclusion of soybean meal and soy protein concentrate on growth performance and fillet quality of juvenile ...
Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore
(Wiley, 2018-02-08)
Herbivore outbreaks often trigger catastrophic overgrazing events in marine macrophyte ecosystems. The sea urchin Paracentrotus lividus, the dominant herbivore of shallow Mediterranean seascapes, is ...
Effects of water pollution and river fragmentation on population genetic structure of invasive mosquitofish
(Elsevier, 2018-05-22)
We analyzed variation at the GPI-2 locus and eleven microsatellite loci of eastern mosquitofish Gambusia holbrooki populations introduced to the Ebro River (Spain), sampling above and below a dam (Flix ...
Weaning strategies affect larval performance in yellowfin seabream (Acanthopagrus latus)
(Elsevier, 2021-03-24)
A 30-day study was carried out to determine the influence of different weaning strategies (WS) on growth and survival rates, stress resistance, digestive enzyme activities and whole body fatty acid ...
Predictive score and probability of CTX-like toxicity in fish samples from the official control of ciguatera in the Canary Islands
(Elsevier, 2019-03-30)
This research identifies factors associated with the contamination by ciguatoxins (CTXs) in a population of fish and proposes a predictive score of the presence of CTX-like toxicity in amberjack samples ...
Egg quality variability in common dentex (Dentex dentex, L.): Comparison of different quality indexes
(Elsevier, 2018-11-10)
The egg quality of two common dentex captive broodstocks were monitored for two consecutive years during their natural spawning season. Volume of spawned eggs, volume of buoyant eggs, fertilization rate, ...
Brewery by-products (yeast and spent grain) as protein sources in gilthead seabream (Sparus aurata) feeds
(Elsevier, 2021-05-17)
Two trials were conducted to test the effect of partial replacement of fishmeal by two brewery industry by-products, yeast and spent grain, included in isoproteic and isolipidic diets for gilthead sea ...
