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

open access: yesJ 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]

open access: yesPlant 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.

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

open access: yesEcol 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 ...

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

open access: yesHoehnea, 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

Effects of low nitrogen supply on biochemical and physiological parameters related to nitrate and water, involving nitrate transporters and aquaporins in Citrus macrophylla

open access: yesPlant Biology, Volume 25, Issue 6, Page 944-955, October 2023., 2023
Reduction of nitrogen fertilization in Citrus sp. impacts physiology, revealing a new relationship between aquaporins, nitrate transporters, and growth of new leaves as a mechanism for ensuring growth. Abstract A reduction in chemical N‐based fertillizer was investigated in Citrus plants.

Acid waters in tank bromeliads: Causes and potential consequences

open access: yesAmerican Journal of Botany, Volume 110, Issue 1, January 2023., 2023
Abstract Premise The consequences of acidity for plant performance are profound, yet the prevalence and causes of low pH in bromeliad tank water are unknown despite its functional relevance to key members of many neotropical plant communities. Methods We investigated tank water pH for eight bromeliad species in the field and for the widely occurring ...

AngleCam: Predicting the temporal variation of leaf angle distributions from image series with deep learning

open access: yesMethods in Ecology and Evolution, Volume 13, Issue 11, Page 2531-2545, November 2022., 2022
Abstract Vertical leaf angles and their variation through time are directly related to several ecophysiological processes and properties. However, there is no efficient method for tracking leaf angles of plant canopies under field conditions. Here, we present AngleCam, a deep learning‐based approach to predict leaf angle distributions from horizontal ...
