Caracterização das assembléias de peixes de riachos de cabeceira no período chuvoso na bacia do rio Cachoeira (SE da Bahia, NE do Brasil)
(Instituto Virtual da Biodiversidade (BIOTA/FAPESP), 2009-06-01)
Visando conhecer a riqueza de espécies e aspectos ecológicos das assembléias ícticas de riachos de cabeceira da Bacia do Rio Cachoeira, foram realizadas coletas de peixes, de variáveis estruturais do ambiente e da água de ...
New evidence for nucleolar dominance in hybrids of Drosophila arizonae and Drosophila mulleri
(2006-12-18)
Drosophila mulleri (MU) and D. arizonae (AR) are cryptic species of the mulleri complex, mulleri subgroup, repleta group. Earlier cytogenetic studies revealed that these species have different regulatory mechanisms of ...

Non-random reef use by fishes at two dominant zones in a tropical, algal-dominated coastal reef
(SPRINGER, 2010)
Habitat use and the processes which determine fish distribution were evaluated at the reef flat and reef crest zones of a tropical, algal-dominated reef. Our comparisons indicated significant differences in the majority ...
Partilha de néctar de Eucalyptus spp., territorialidade e hierarquia de dominância em beija-flores (Aves: Trochilidae) no sudeste do Brasil
(2003-06-01)
Territorial behavior in hummingbirds minimizes competition through aggressive interactions, resulting in a dominance hierarchy among species and individuals. Interactions among seven hummingbird species visiting flowering ...
Herbivory and presence of a dominant competitor interactively affect salt marsh plant diversity
(Wiley Blackwell Publishing, Inc, 2017-11)
Question: Do herbivory and the presence of a dominant grass competitor interactively affect herbaceous communities and assembly rules in a SW Atlantic salt marsh?. Location: Upper salt marsh, Mar Chiquita coastal lagoon, ...
Herbivores safeguard plant diversity by reducing variability in dominance
(Wiley Blackwell Publishing, Inc, 2018-01)
Reductions in community evenness can lead to local extinctions as dominant species exclude subordinate species; however, herbivores can prevent competitiveexclusion by consuming otherwise dominant plant species, thus ...
Effect of male aggressivity profile on female chemical choice in Nile tilapia
(2019-09-13)
Selection favors females that make use of reliable information on the genetic quality of males, which affects mating decisions. Although studies have shown that females prefer dominant males, it may not be adaptive for ...
