Unifying microorganisms and macrograzers in rocky shore ecological networks
(2023)
Over the past decades, our understanding of the vital role microbes play in ecosystem processes has greatly expanded. However, we still have limited knowledge about how microbial communities interact with larger organisms. ...
Seasonal fluctuation of nematodes trophic groups in the ecotonal forest of cypress (Austrocedrus chilensis) in ArgentinaFluctuación estacional de grupos tróficos de nemátodos en un bosque central de Austrocedrus chilensis en Argentina
(Universidad Austral de Chile, Facultad de Ciencias Forestales y Recursos Naturales., 1996)
Species richness and functional structure of fish assemblages in three freshwater habitats: effects of environmental factors and management
(Wiley-Blackwell, 2019-08-12)
In this study, the inverted trophic hypothesis was tested in the freshwater fish communities of a reservoir. The distribution of fish species in three freshwater habitats in the Jurumirim Reservoir, Brazil, was examined ...
Macroinvertebrate trophic responses to nutrient addition in a temperate stream in South America
(E Schweizerbartsche Verlags, 2013-01)
The present continuous anthropogenic pressure has resulted in an enhancement of nutrient inputs into rivers and streams. This situation has worsened, mainly in agricultural areas, causing an accelerated eutrophication. ...
Ecosystem Dynamics Under “top-down” and “bottom-up” Control Situations Generated by Intensive Harvesting Rates
(Hidrobiológica, 2011-01-01)
“Top-down” and “bottom-up” control processes in exploited ecosystems have been characterised using their impacts on the mean trophic level of catches, changes in biomass, and certain ecosystem attributes. Most scientific ...
Resource partitioning between two young-of-year cownose rays Rhinoptera bonasus and R. brasiliensis within a communal nursery inferred by trophic biomarkers
(Wiley-Blackwell, 2019-05-01)
Although interspecific trophic interactions plays a principal role within elasmobranch communal nurseries, little is known over variation in foraging strategies adopted by young-of-year of sympatric species. To test the ...
Sympatric otariids increase trophic segregation in response to warming ocean conditions in Peruvian Humboldt Current System
(Public Library of Science, 2022)
Determining trophic habits of predator communities is essential to measure interspecific interactions and response to environmental fluctuations. South American fur seals, Arctocephalus australis (SAFS) and sea lions Otaria ...
Bird diversity patterns in Neotropical temperate farmlands: The role of environmental factors and trophic groups in the spring and autumn
(Wiley Blackwell Publishing, Inc, 2012-08)
Productivity, habitat heterogeneity and environmental similarity are of the most widely accepted hypotheses to explain spatial patterns of species richness and species composition similarity. Environmental factors may ...
Picoplankton abundance and cytometric group diversity along a trophic and latitudinal lake gradient
(Inter-Research, 2013-03)
The picoplankton (PP) is responsible for major ecosystem functions in most aquatic environments. However, not much is known about the factors that regulate its total abundance and community structure. Using flow cytometry ...
Analysis of the Ecosystem Structure of Laguna Alvarado, Western Gulf of Mexico, by Means of a Mass Balance Model.
(Estuarine Coastal and Shelf Science, 2007-01-01)
Alvarado is one of the most productive estuary-lagoon systems in the Mexican Gulf of Mexico. It has great economic and ecological importance due to high fisheries productivity and because it serves as a nursery, feeding, ...
