Vertebrate florivory of vascular epiphytes: the case of a bromeliad

Braz. j. biol; 79 (2), 2019
Abstract The avoidance of vertebrate herbivory is thought to be one of the possible drivers for the evolution of epiphytism. Scarce literature suggests that epiphyte herbivory is mainly related to insect attack on reproductive structures. In a pine-oak forest we observed almost all inflorescences of an ...

Galápagos macroalgae: A review of the state of ecological knowledge

Rev. biol. trop; 65 (1), 2017
Abstract:Previous work has highlighted the critical role of macroalgal productivity and dynamics in supporting and structuring marine food webs. Spatio-temporal variability in macroalgae can alter coastal ecosystems, a relationship particularly visible along upwelling-influenced coastlines. As a result o...

Frugivory and seed dispersal of Solanum granuloso-leprosum Dunal (Solanaceae) by birds in deciduous seasonal forest

Braz. j. biol; 76 (4), 2016
Abstract The goal of this study was to identify which bird species consume Solanum granuloso-leprosum fruits and disperse its seeds. 60 hours of focal observations were carried out between April and May 2006 on the edge of a deciduous forest fragment in the Uruguay River region, Rio Grande do Sul state, ...

Resource allocation in Copaifera langsdorffii (Fabaceae): how supra-annual fruiting affects plant traits and herbivory?

Rev. biol. trop; 64 (2), 2016
AbstractPlants have limited resources to invest in reproduction, vegetative growth and defense against herbivorous. Trade-off in resources allocation promotes changes in plant traits that may affect higher trophic levels. In this study, we evaluated the trade-off effect between years of high and low frui...

Interactions between frugivorous bats (Chiroptera: Phyllostomidae) and Piper tuberculatum (Piperaceae) in a tropical dry forest in Valle del Cauca, Colombia

Rev. biol. trop; 64 (2), 2016
AbstractIn any ecosystem, fruits are resources that vary in time and space as well as in nutritional content. Coexistence of species from a trophic guild depends on the division and use of resources. Therefore, the organisms that depend on them as a food source, tend to show a certain degree of specializ...
