Exploring community assembly through an individual-based model for trophic interactions
(Elsevier B.V., 2009-01-10)
Traditionally, the dynamics of community assembly has been analyzed by means of deterministic models of differential equations. Despite the theoretical advances provided by such models, they are restricted to questions ...
A critical analysis of the ubiquity of linear local-regional richness relationships
(2013-07-01)
Synthesis Despite theoretical criticisms, the ubiquity of linear relationships between local and regional species richness has long been used to justify it as a valid framework to conclude that local communities are not ...
Trait contributions to fish community assembly emerge from trophic interactions in an individual-based model
(2013-02-04)
Community ecology seeks to understand and predict the characteristics of communities that can develop under different environmental conditions, but most theory has been built on analytical models that are limited in the ...
On the mismatch in the strength of competition among fossil and modern species of planktonic Foraminifera
(2019-12-01)
Aim: Many clades display the macroevolutionary pattern of a negative relationship between standing diversity and diversification rates. Competition among species has been proposed as the main mechanism that explains this ...
The bacterial community structure of hydrocarbon-polluted marine environments as the basis for the definition of an ecological index of hydrocarbon exposure
(Japanese Soc Microbial Ecology, 2014-06-24)
The aim of this study was to design a molecular biological tool, using information provided by amplicon pyrosequencing of 16S rRNA genes, that could be suitable for environmental assessment and bioremediation in marine ...
Community size can affect the signals of ecological drift and niche selection on biodiversity
(2020-06-01)
Ecological drift can override the effects of deterministic niche selection on small populations and drive the assembly of some ecological communities. We tested this hypothesis with a unique data set sampled identically ...
Ecological and evolutionary consequences of living in a defaunated world
(2013-07-01)
Defaunation, the loss or population decline of medium and large native vertebrates represents a significant threat to the biodiversity of tropical ecosystems. Here we review the anthropogenic drivers of defaunation, provide ...
Modelos dinâmicos de assembléia
(2010-07-20)
The structure of an ecological community is shaped by several temporally varying mechanisms. Such mechanisms depend in a large extent on species interactions, which are themselves manifestations of the community's own ...
Is the microcosm approach using meiofauna community descriptors a suitable tool for ecotoxicological studies?
(Elsevier B.V., 2018-01-01)
The usual approaches used in ecological risk assessment have been based on individual and population level standard procedures. Although these have been important tools to assess adverse effects on ecosystems, they are ...
Ecologia de comunidade de Bethylidae (Hymenoptera, Chrysidoidea) da Reserva Ecológica do Roncador, Brasília, Distrito Federal, Brasil
(1999)
Bethylidae specimens from the Reserve were studied in its ecological and faunistic aspects. The material was collected by Malaise and Window traps simultaneously in ten different areas of the Reserve during four years. The ...
