Nectar ecology of the endemic epiphytic hummingbird-pollinated bromeliad Vriesea altodaserrae: secretion dynamics and pollinator visitation pattern

open access: yesActa Botânica Brasílica, 2018
Hummingbirds are the main pollinators of most bromeliad species, whose nectar traits usually respond to the selective pressures imposed by pollinators.

The Structure and Biological Activities With Health Benefits of Luteolin Glycosides From Plants

open access: yesThe Scientific World Journal, Volume 2025, Issue 1, 2025.
Luteolin, a flavonoid in the class of flavones, is found in various plant families. Luteolin is present in plants as both aglycone and glycosides. Luteolin glycosides are found in plants more often than aglycone. In this review, the structure, metabolism, biological activities, and health benefits of luteolin glycosides present in plants are summarized

Ecological stoichiometry of the epiphyte community in a subtropical forest canopy

open access: yesEcology and Evolution, Volume 9, Issue 24, Page 14394-14406, December 2019., 2019
Forest canopies are occupied by nearly 600 epiphytic species (including lichens, bryophytes, ferns, and spermatophytes) in a subtropical montane moist evergreen broad‐leaved forest in Southwest China. However, the nutrient status of epiphytes and their adaptations to nutrient deficiencies in the forest canopy remain unclear.

The Invisible Species: Big Data Unveil Coverage Gaps in the Atlantic Forest Hotspot

open access: yesDiversity and Distributions, Volume 30, Issue 12, December 2024.
ABSTRACT Aim Rapid technological advancements and the biodiversity crisis have motivated efforts to document species before their extinction. However, taxonomic coverage gaps, where certain species are underrepresented in biodiversity databases, can distort our understanding of ecosystems.

Macroevolution of the plant–hummingbird pollination system

open access: yesBiological Reviews, Volume 99, Issue 5, Page 1831-1847, October 2024.
ABSTRACT Plant–hummingbird interactions are considered a classic example of coevolution, a process in which mutually dependent species influence each other's evolution. Plants depend on hummingbirds for pollination, whereas hummingbirds rely on nectar for food.

Expansions and contractions of the inverted repeat, as well as gene loss and potential pseudogenization shape plastome evolution in Hechtioideae (Bromeliaceae, Poales)

open access: yesJournal of Systematics and Evolution, Volume 62, Issue 3, Page 421-437, May 2024.
Analysis of complete plastome sequences obtained by whole‐genome sequencing improved statistical support across different phylogenetic depths in Hechtioideae and allowed the identification of highly informative loci previously unexplored in this lineage.

The Use of Bromeliads as Biomonitors of Air Quality: A Global Review

open access: yesInternational Journal of Forestry Research, Volume 2024, Issue 1, 2024.
Air pollution is a global problem in urban and rural areas, mainly related to vehicular traffic and industrial activities. Bromeliads have been widely used globally for active and passive air quality monitoring. However, a systematic review to facilitate the access and analysis of this information is yet to be made available. The objective of this work
