Molecular phylogenetics, historical biogeography and character evolution in Dyckia (Bromeliaceae, Pitcairnioideae) [PDF]

open access: yesBotanical Journal of the Linnean Society, 2016
Dyckia is a xeromorphic bromeliad genus with 168 species distributed throughout south-eastern South America, with the centre of diversity in Brazil. Previous phylogenetic studies based on sequence data revealed, in general, poor resolution among species.

Topography, Seed Dispersal, and Climate Change Reduce Future Habitat for an Endangered Tropical High‐Altitude Plant

open access: yesBiological Diversity, Volume 2, Issue 2-3, Page 95-105, September 2025.
Combining topographic preferences of endangered high‐elevation Puya raimondii rosettes, seed dispersal distances, and future climate scenarios, we project habitat availability in the year 2100 in the Cordillera Blanca, Peru. We predict a significant decrease in occupied habitat patches, with almost complete loss for the +5°C climate change scenario ...

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

open access: yesNordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Disentangling the effects of key innovations on the diversification of Bromelioideae (bromeliaceae). [PDF]

open access: yes, 2013
The evolution of key innovations, novel traits that promote diversification, is often seen as major driver for the unequal distribution of species richness within the tree of life.

Influence of Seasonality and Habitat Variability on the Thermal Ecology of Gymnodactylus geckoides Spix, 1825 (Squamata, Phyllodactylidae) in Semi‐Arid Caatinga Biome in Northeastern Brazil

open access: yesAustral Ecology, Volume 50, Issue 7, July 2025.
ABSTRACT Temperature trends influence the behaviour of animals, mainly ectotherms, with thermoregulation led by a contingent of biotic and abiotic factors, such as seasonality and habitat quality, especially regarding nocturnal lizards. Therefore, in the present study, we aimed to analyse the microhabitat use and thermal ecology of Gymnodactylus ...

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.
