Leaf damage and density-dependent effects on six Inga species in a neotropical forest
(Universidad de Costa Rica, 2012)
The relationship between leaf nitrogen, nitrogen metabolites and herbivory in two species of Nyctaginaceae from the Brazilian Cerrado
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Guapira graciliflora and Neea theifera are taxonomically related species of the tribe Pisoneae. Both species are found in the same environment, the Brazilian Cerrado, and therefore, are subjected to similar selective ...
Quantifying invertebrate-mediated herbivory across an anthropogenic disturbance gradient in amazonian forestsQuantificando herbivoria mediada por invertebrados ao longo de um gradiente de perturbação antropogênica em florestas amazônicas
(Universidade Federal de LavrasPrograma de Pós-Graduação em Ecologia AplicadaUFLAbrasilDepartamento de Biologia, 2017)
How does cattle raising affect bird communities in the delta of the Paraná River?
(Elsevier Gmbh, 2020-10-18)
We hypothesize that the presence of cattle should increase environmental heterogeneity and therefore maintain more diverse bird communities. Therefore, we analyzed the changes in the structure of vegetation and diversity ...
Fluctuating asymmetry, leaf thickness and herbivory in Tibouchina granulosa: an altitudinal gradient analysis
(Arthropod-Plant Interactions, 2018)
Local spatial distribution of stream macroalgae – does gastropod activity matters?
(2021-12-01)
The effects of gastropod Biomphalaria sp. on the benthic algae community (micro and macroalgae) were experimentally studied in an unshaded artificial stream. Using artificial substrates, two treatments were tested: with ...
Testing the role of biotic stress in the stress gradient hypothesis. Processes and patterns in arid rangelands
(Wiley Blackwell Publishing, Inc, 2011-06)
Since many arid ecosystems are overstocked with domestic herbivores, biotic stress could have a stronger influence in modulating the balance of species interactions than expected from the stress gradient hypothesis (SGH). ...
Is foliar flammability of woody species related to time since fire and herbivory in northwest Patagonia, Argentina?
(Wiley Blackwell Publishing, Inc, 2012-10)
Question: In northwest Patagonia burning of fire-resistant forests creates a community-level positive feedback towards increased fire occurrence because of successional replacement by fire-prone shrublands. We hypothesize ...
Nutrient and herbivore alterations cause uncoupled changes in producer diversity, biomass and ecosystem function, but not in overall multifunctionality
(Nature Publishing Group, 2017-12-01)
Altered nutrient cycles and consumer populations are among the top anthropogenic influences on ecosystems. However, studies on the simultaneous impacts of human-driven environmental alterations on ecosystem functions, and ...
