In vitro culture of Vriesea gigantea and Vriesea philippocoburgii: two vulnerable bromeliads native to Southern Brazil [PDF]

Brazilian Archives of Biology and Technology, 2005
Micropropagation studies were carried out using the seeds for establishing an in vitro culture of Vriesea gigantea and Vriesea philippocoburgii. Germination rate of V. gigantea was higher than of V. philippocoburgii. Plantlets of V. philippocoburgii gave

In vitro germination and growth of Vriesea incurvata Gaudich. (Bromeliaceae)

Acta Agronómica, 2018
Vriesea incurvata in the natural environment shows some difficulties associated to the low seed germination capacity. Aiming to provide basis for the seedlings production, the results of the seeds germination percentage and the initial growth of V ...

Drivers of bromeliad leaf and floral bract variation across a latitudinal gradient in the Atlantic Forest. [PDF]

J Biogeogr, 2020
Abstract Aim Understanding the complex interaction and relative contributions of factors involved in species and trait diversification is crucial to gain insights into the evolution of Neotropical biodiversity. Here, we investigated the drivers of morphological variation in bromeliads along a latitudinal gradient in a biodiversity hotspot.

Evolution of UV reflection in bee- and bird-pollinated flowers. [PDF]

Plant Biol (Stuttg)
Pollinators shape floral UV reflection across angiosperms, supporting the bee‐avoidance hypothesis in red flowers and revealing mixed patterns in white and yellow flowers. Abstract Floral colour is a key trait mediating plant–pollinator interactions, with UV reflection hypothesized to evolve in response to the effectiveness of pollinators.

Plant growth-promoting traits of yeasts isolated from the tank bromeliad Vriesea minarum L.B. Smith and the effectiveness of Carlosrosaea vrieseae for promoting bromeliad growth. [PDF]

Braz J Microbiol, 2021
Yeasts can play important roles in promoting plant growth; however, little information is available in this regard for yeasts in water of bromeliad tanks. Here, we characterize the ability of 79 yeast isolates from tank bromeliad Vriesea minarum, an endangered species, to solubilize phosphate, secrete siderophores, and synthesize indole-3-acetic acid ...

Seed morphology of Vriesea friburgensis var. paludosa L.B. Sm. (Bromeliaceae) [PDF]

Hoehnea, 2014
The Brazilian Atlantic Forest is a biodiversity hotspot, and bromeliads are omnipresent in this biome. This study was aimed at characterizing both morphological and histochemical aspects of Vriesea friburgensis var. paludosa L.B. Sm. seeds. The seeds are

Phylogenetic Conservatism and Ambient Temperature Shape Spatial Variation in Bat Occupancy and Species Richness Along a Subtropical Elevational Gradient. [PDF]

Ecol Evol
We investigated how ecological traits and evolutionary history influence the occupancy of 27 bat species along a 1300 m elevational gradient in subtropical Brazil. While ecological traits poorly predicted species' responses, occupancy varied with temperature in a phylogenetically conserved manner, suggesting that elevational niches in bats may be ...
