Phylogenomic evidence reveals non‐monophyly of Paepalanthoideae (Eriocaulaceae) and challenges the broad concept of Paepalanthus

open access: yesTAXON, Volume 74, Issue 5, Page 1054-1066, October 2025.
Abstract Eriocaulaceae is a pantropical family of approximately 1200 species across 18 genera, with its highest diversity in the Neotropical region. Traditionally, the family has been divided into two subfamilies, Eriocauloideae and Paepalanthoideae, based on floral traits. Here, we use target‐capture sequencing of nuclear markers to test the monophyly

A review of the biologic and pharmacologic role of docosapentaenoic acid n-3 [v2; ref status: indexed, http://f1000r.es/41a]

open access: yesF1000Research, 2014
Fish oil contains a complex mixture of omega-3 fatty acids, of which eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA) are the three predominant forms.

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 ...

Draft genome of Puya raimondii (Bromeliaceae), the Queen of the Andes

open access: yesGenomics, 2021
Puya raimondii, the Queen of the Andes, is an endangered high Andean species in the Bromeliaceae family. Here, we report its first genome to promote its conservation and evolutionary study. Comparative genomics showed P. raimondii diverged from Ananas comosus about 14.8 million years ago, and the long terminal repeats were likely to contribute to the ...

So Young, So Rich: Habitat Shifts Combined With Trait Evolution Promoted Species Radiation in Senecio in the Andes

open access: yesJournal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim The outstanding Andean biodiversity has been linked to the occurrence of evolutionary radiations that are common among high‐elevation plant lineages. One of the most iconic examples is found in the species‐rich genus Senecio, with an impressive variation in growth forms and habitat preference.

Marcescence and prostrate growth in tree ferns are adaptations to cold tolerance

open access: yesEcography, Volume 2025, Issue 6, June 2025.
Cold tolerance strategies in plants vary from structural to biochemical permitting many plants to survive and grow on sites that experience freezing conditions intermittently. Although tree ferns occur predominantly across the tropics, they also occur in temperate zones and occasionally in areas that experience sub‐zero temperatures, and how these ...

Queen of the Andes: the ecology and conservation of Puya raimondii

open access: yesFrontiers in Conservation Science
Puya raimondii is the world’s largest bromeliad and a prime example of a “charismatic megaflora”. Indeed, its grand stature and remarkable once-in-a-lifetime flowering event have earned it the name “Queen of the Andes”.
