• We investigated paired bacteria and protists across ecosystems at the global scale. Predatory dominated in soils, phototrophs aquatic environments. positively correlated with bacterial richness natural soils. Anthropogenic factors might have negative effects on microbiome trophic structures. The colossal project of mapping Earth is rapidly advancing, a focus individual microbial groups. Howev...

Because research on nematode involvement in trophic interactions, foodweb structure, and biodiversity is constrained by lack of an overview of nematode feeding habits, this outline presents a consensus of current thought on nematode feeding habits. The source of food is fundamental to trophic interactions and provides the basis for our definitions of the essential feeding types: 1) plant feeder...

Understanding interspecific interactions, and the influences of anthropogenic disturbance and environmental change on communities, are key challenges in ecology. Despite the pressing need to understand these fundamental drivers of community structure and dynamics, only 17% of ecological studies conducted over the past three decades have been at the community level. Here, we assess the trophic s...

The present study provides data on the trophic structure of benthic macroinvertebrate communities in mountainous and semi-mountainous small streams river sections belonging to Mesta, Struma Vardar River catchments from 7th Ecoregion. macroinvertebrates were assigned seven Functional Feeding Groups. We analyzed their dynamics different seasons. level similarity between sampling localities was co...

Models predict that food-web structure is regulated by both consumers and resources, and the strength of this control is dependent on trophic position and food-web length. To test these hypotheses, a meta-analysis was conducted of 11 fish (consumer)-by-nutrient (resource) factorial plankton community experiments. As predicted, zooplankton biomass was under strong consumer control but was weakly...
