Insulin binding and receptor tyrosine kinase activity in skeletal muscle of carnivorous and omnivorous fish

, 1994
We characterized the insulin receptors in skeletal muscle from several fish species with different nutritional preferences: brown trout (Salmo trutta fario), gilthead sea bream (Sparus aurata), tilapia (Tilapia mossambica), and carp (Cyprinus carpio ...

Global sensitivity analysis of an end-to-end marine ecosystem model of the North Sea : factors affecting the biomass of fish and benthos [PDF]

, 2014
Comprehensive analysis of parameter and driver sensitivity is key to establishing the credibility of models of complex systems. This is especially so for models of natural systems where experimental manipulation of the real-world to provide controlled ...

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Effect of dietary plant proteins on flesh quality traits of rainbow trout (Oncorhynchus mykiss)

Italian Journal of Animal Science, 2011
The reduction of fish meal in aquaculture feeds is a priority goal for the further expansion and sustainability of the farmed fish production. Some encouraging results, also in carnivorous species as salmonids, are obtained by partial and even total ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

Journal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Mercury exposure and source tracking in distinct marine-caged fish farm in southern China

, 2017
Coasts of South China have experienced an unprecedented growth in its marine-caged fish industry. We analyzed mercury concentrations and stable mercury isotope ratios in fourteen fish species from two cage-cultured farms in Southern China.

Data and code for 'Climate-driven zooplankton shifts cause large-scale declines in food quality for fish'

, 2023
Zooplankton are the primary energy pathway from phytoplankton to fish. Yet, there is limited understanding about how climate change will modify zooplankton communities and the implications for marine food webs globally.

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Distribuição de selênio em organismos marinhos da Baía de Guanabara/ RJ Distribution of selenium in marine organisms from Guanabara Bay/ RJ

Química Nova, 2007
The study assessed selenium concentrations in the muscle tissues and liver samples of three fish species and in the soft tissues of a mussel species. The samples were analyzed by GF-AAS using Zeeman background correction.
