The α and β diversities in the fish assemblages of the promiss̃ao reservoir (SP-Brazil): Scales, complexities and ecotone heterogeneity
(2001-01-01)
This paper characterizes the fish assemblage and its interaction with different ecotones within the reservoir. The transformation of a river basin into a cascade of reservoirs produces new ecotones which interact differentially ...
Saproxylic Beetle Assemblage Selection as Determining Factor of Species Distributional Patterns: Implications for Conservation
(Oxford Univ Press, 2016)
The knowledge of the distributional patterns of saproxylic beetles is essential for conservation biology due to the relevance of this fauna in the maintenance of ecological processes and the endangerment of species. The ...
Substrate-dependent differences between the structures of epiphytic and epilithic diatom assemblages off the southwestern coast of the Gulf of California
(Botanica Marina, 2012)
To test the postulate that diatom assemblage structures differ between those growing on macroalgae and those on rocks used as substratum by macroalgae, we analyzed 29 samples of macroalgae and 15 of rocky substrata from ...
Influence of artificial reefs on fish assemblage of the Barra Bonita Reservoir (São Paulo, Brazil)
(2001-12-01)
This paper deals with the effects of introduced artificial reefs on the diversity of freshwater fish communities in lentic and lotic zones of a very impacted river in southeastern Brazil. To accomplish this goal, artificial ...

Hypogaeic anti epigaeic ant (Hymenoptera: Formicidae) assemblages of atlantic costal rainforest and dry mature and secondary amazon forest in Brazil: Continuums or communities
(2000-12-01)
Meat, flour and sugar baits were used on the soil surface and buried to examine species composition of the ant fauna in three separate tropical forests in Brazil, and to control for the effect of the regional faunal pool. ...
Homogenization of diatom assemblages is driven by eutrophication in tropical reservoirs
(2021-11-01)
Eutrophication is one of the most widespread causes of biotic homogenization in freshwater ecosystems. Biotic homogenization can be characterized as reductions in local diversity (alpha) and occupation of available niches ...
