Is top-down control by predators driving insect abundance and herbivory rates in fragmented forests?
(2012)
The effects of forest fragmentation on ecological interactions and particularly on food webs have scarcely been analysed. There is usually less herbivory in forest fragments than in continuous forests. Here we hypothesize ...
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 ...
Physical stress modifies top-down and bottom-up forcing on plant growth and reproduction in a coastal ecosystem
(Ecological Society of America, 2015-08)
Bottom-up and top-down effects act together to exert strong control over plant growth and reproduction, but how physical stress modifies those interactive forces remains unclear. Even though empirical evidence is scarce, ...
Top-down and bottom-up regulation of planktonic communities in a warm temperate wetland
(Oxford University Press, 2010-02)
This field experimental study simultaneously analysed the effects of predation (top-down) and nutrients (bottom-up) on planktonic communities (phytoplankton, zooplankton, heterotrophic nanoflagellates and ciliates) in a ...
O que controla o crescimento do Fitoplâncton em lagoas costeiras tropicais? um modelo para a lagoa de Extremoz (RN)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-graduação em Engenharia SanitáriaSaneamento Ambiental; Meio Ambiente; Recursos Hídricos e Hidráulica, 2014-03-26)
The phytoplankton growth is dependent of several abiotic (nutrients, temperature)
and biotic (predation by zooplankton) variables. In this work, a mathematical model was
developed in Stella software to understand ...
