Long‐term community dynamics in vascular epiphytes on Annona glabra along the shoreline of Barro Colorado Island, Panama

Journal of Ecology, Volume 109, Issue 4, Page 1931-1946, April 2021., 2021
We analysed data from three censuses of epiphytes growing on Annona glabra trees along the shore of Barro Colorado Island, Panama, spanning 21 years. Our study shows that previously reported short‐term patterns of epiphyte community dynamics hold true in the long term.

Climate influences the response of community functional traits to local conditions in bromeliad invertebrate communities

Ecography, Volume 44, Issue 3, Page 440-452, March 2021., 2021
Functional traits determine an organism's performance in a given environment and as such determine which organisms will be found where. Species respond to local conditions, but also to larger scale gradients, such as climate. Trait ecology links these responses of species to community composition and species distributions.

Fertility of Vriesea gigantea Gaud. (Bromeliaceae) in southern Brazil [PDF]

American Journal of Botany, 2007
Plant fertility is a central subject of many questions in plant evolutionary and conservation biology. Pollen availability, abiotic resources, and flowering pattern can limit fruit and seed production. Open pollination and pollen supplementation studies are used to estimate any pollen limitation in natural populations.

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 ...

Different processes shape the patterns of divergence in the nuclear and chloroplast genomes of a relict tree species in East Asia

Ecology and Evolution, Volume 10, Issue 10, Page 4331-4342, May 2020., 2020
We infer that different markers reflecting divergent processes may owe to the heredity and ploidy difference of genomes, while divergent extent of significant patterns in northern and southern regions may owe to different population history between regions.

Direct sampling technique of bees on Vriesea philippocoburgii (Bromeliaceae, Tillandsioideae) flowers [PDF]

Biotemas, 2004
In our study on Vriesea philippocoburgii Wawra pollination, due to the small proportion of flowers in anthesis on a single day and the damage caused to inflorescences when netting directly on flowers, we used the direct sampling technique (DST) of bees ...
