trophic levels, so they would prove to be best indicators and can reflect the relationship between environmental disturbance and trophic levels in a better way, because bio accumulation and metabolic capacity of diet increases in animals as positions increases in the food chain (Alleva et al., ...
(1) Three tropical grassland systems were examined in the Serengeti region of Tanzania with respect to changes in grass off-take by ungulates, small mammals and grasshoppers, within the annual cycle. These groups comprised most of the herbivore trophic level. (2) Within all three grassland system...
Trophic levels responded differently to these stressors (QM = 22.28,p = 0.035; Supplementary Table3). Primary producers benefited from OA, while meso-predators and top-predators remained unaffected. Combining meso-predators and top-predators (Predator) resulted in a marginal negative OA eff...
Abstract. The ingestion of carnivores and omnivores was determined during the investigation of higher trophic levels in a North Adriatic benthic community. The ingestion rate was calculated from respiration data using a respiration-production equation and an assumed assimilation efficiency. In the case ...
In particular, the biomass of the high trophic levels decreased whereas the lower trophic levels displayed a relative stability or an increase. This could be linked to a fishing effect due to a release of predation on the lower trophic levels of the demersal fish community. In Senegal, the ...
This region is known to have high primary productivity (Vernet et al., 2008) in some coastal regions, known as biological ‘hotspots’ (Sherrell et al., 2018), featuring abundant organisms at all trophic levels (Kavanaugh et al., 2015; Schofield et al., 2013). The regional productivity ...
State of the art and challenges for physical models of biophysical interaction in the North Atlantic State of the art and challenges for biogeochemical and lower trophic level models of the North Atlantic Higher trophic levels modelling: state of the art, challenges and gaps Climate change projection...
The year 2023 marks the mid-point of the 15-year period envisaged to achieve the Sustainable Development Goals, targets for global development adopted in September 2015 by all United Nations Member States. To help track where we are on this journey, and to amplify success stories, in this ...
Differential responses among the trophic levels resulted in consistent rainfall-driven shifts in the shape of biomass pyramids across sites (i.e., no site vs. rainfall interactions for biomass ratios; Fig.2d, Table1). Biomass pyramids comprised of all predators (meso and top predators) consistentl...
zooplankton provides important sinks and vectors for their transport in the marine environment by egestion through sinking fecal pellets and decaying biomass (Berrojalbiz et al.2009). Moreover, they transfer oil hydrocarbons to higher trophic levels in the oceanic food web through cellular ingestion ...
