Environmental filters and biotic interactions drive species richness and composition in ecotone forests of the northern Brazilian Amazonia
(Museu Paraense Emílio GoeldiBrasil, 2021-09-07)
The structure of tree communities in tropical forests depends on environmental filters and biotic interactions such as competition and facilitation. Many ecotone forests in Northern Amazonia are intriguingly populated by ...
Disentangling the co-structure of multilayer interaction networks: degree distribution and module composition in two-layer bipartite networks
(Nature Publishing Group, 2017-11)
Species establish different interactions (e.g. antagonistic, mutualistic) with multiple species, forming multilayer ecological networks. Disentangling network co-structure in multilayer networks is crucial to predict how ...
Node-by-node disassembly of a mutualistic interaction web driven by species introductions
(National Academy of Sciences, 2013-10)
Interaction webs summarize the diverse interactions among species in communities. The addition or loss of particular species and the alteration of key interactions can lead to the disassembly of the entire interaction web, ...
Mixed biofilms formed by C. albicans and non-albicans species: a study of microbial interactions
(Sociedade Brasileira De Pesquisa Odontologica, 2016-01-01)
Most Candida infections are related to microbial biofilms often formed by the association of different species. The objective of this study was to evaluate the interactions between Candida albicans and non-albicans species ...
Tree species attributes and facilitation of natural regeneration in heterogeneous planting of riparian vegetation
(Ipef-inst Pesquisas Estudos Florestais, 2015-06-01)
Ecological interactions among species, both positive and negative, have a strong influence on the structure of plant communities and their comprehension can contribute to the improvement of techniques for ecological ...
Species abundance and asymmetric interaction strength in ecological networks
(Wiley Blackwell Publishing, Inc, 2007-07)
The strength of interactions among species in a network tends to be highly asymmetric. We evaluate thehypothesis that this asymmetry results from the distribution of abundance among species, so that speciesinteractions ...
Ecological niche similarities of Peponapis bees and non-domesticated Cucurbita species
(ELSEVIER SCIENCE BV, 2011)
Peponapis bees are considered specialized pollinators of Cucurbita flowers, a genus that presents several species of economic value (squashes and pumpkins). Both genera originated in the Americas, and their diversity ...
What makes a species central in a cleaning mutualism network?
(WILEY-BLACKWELL, 2010)
Mutualisms often form networks of interacting species, characterized by the existence of a central core of species that potentially drive the ecology and the evolution of the whole community. Centrality measures allow ...
Fatores associados à diversidade beta de interações entre plantas e beija-flores na Mata Atlântica
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2021-09-29)
The composition of species in communities can vary in space and along geographic and environmental gradients. These changes in species composition can affect the interactions between organisms, which may vary according to ...
