Relating trophic resources to community structure: a predictive index of food availability [PDF]

Royal Society Open Science, 2017
The abundance and the distribution of trophic resources available for consumers influence the productivity and the diversity of natural communities. Nevertheless, assessment of the actual abundance of food items available for individual trophic groups ...

Bridging the gap from ocean models to population dynamics of large marine predators: A model of mid-trophic functional groups [PDF]

, 2009
The modeling of mid-trophic organisms of the pelagic ecosystem is a critical step in linking the coupled physical–biogeochemical models to population dynamics of large pelagic predators. Here, we provide an example of a modeling approach with definitions

Neonicotinoid Seed Treatments Influence Soil Nematode Taxonomic Composition and the Soil Microbial Cooccurrence Networks

Phytobiomes Journal, 2023
Neonicotinoid insecticides are widely used to control early-season and foliar-feeding pests. Some studies have revealed their nontarget impacts on pollinators and other invertebrates but few investigated their effects on soil microbiota.

Trophic links between functional groups of arable plants and beetles are stable at national scale [PDF]

, 2011
1. There is an urgent need to accurately model how environmental change affects the wide-scale functioning of ecosystems, but advances are hindered by a lack of knowledge of how trophic levels are linked across space.

Biodiversity of Nematode Communities Associated with Wheat (Triticum aestivum L.) in Southern Morocco and Their Contribution as Soil Health Bioindicators

Diversity, 2022
Soil nematodes are major soil organisms known to reduce wheat production worldwide. However, they are a crucial part of soil biodiversity. Due to the limited data available regarding nematode biodiversity associated with cereal crops in Morocco, a survey

Composition and location of trophic groupings of zoobenthos in the Arctic Ocean

E3S Web of Conferences, 2023
This study is devoted to the distribution of trophic groups of zoobenthos in the Arctic Ocean. The patterns of distribution of detritus feeders, seston feeders, and predators along the bottom of the Arctic polar basin are analyzed. The object of the study is the geoecology of the distribution of food groups of benthic animals in the polar regions.

Effects of silver, gold and platinum nanoparticles on selected nematode trophic groups

Journal of Horticultural Research, 2023
Abstract Nematodes represent different trophic groups in the soil. They therefore play an important role in the soil environment: they regulate populations of other soil organisms, mineralize nutrients into plant-available forms, provide a source of food for other soil organisms and feed on pathogenic organisms and plant pests.

Generation of raptor diversity in Europe: linking speciation with climate changes and the ability to migrate [PDF]

PeerJ, 2022
Europe holds a rich community of diurnal birds of prey, and the highest proportion of transcontinental migratory raptorial species of any landmass. This study will test the hypotheses that the high diversification of the raptor assemblage in Europe is a ...
