El néctar de especies de Puya como recurso para picaflores Altoandinos de Ancash, Perú [PDF]
Revista Peruana de Biología, 2013 En la región altoandina de Ancash la mayor diversidad de flores ornitófilas se encuentran en ambientes de matorral, en contraste a roquedales y pajonales, en los que encontramos rodales de bromelias del género Puya, cuyo néctar podría constituir un ...

Distribución potencial de puya raimondii harms en futuros escenarios del cambio climático [PDF]
Revista de Investigaciones Altoandinas - Journal of High Andean Research, 2020 The anthropogenic climate change is a major cause of biodiversity loss. In this context, there is a need for studies based on the future impacts of large-scale climate change to propose conservation strategies for endangered species such as Puya raimondii Harms, a species of bromeliad endemic to the Andes of Peru and Bolivia.

nlstimedist: An r package for the biologically meaningful quantification of unimodal phenology distributions [PDF]
Methods in Ecology and Evolution, Volume 10, Issue 11, Page 1934-1940, November 2019., 2019 Abstract Phenological investigation can provide valuable insights into the ecological effects of climate change. Appropriate modelling of the time distribution of phenological events is key to determining the nature of any changes, as well as the driving mechanisms behind those changes.

New PhytologistSummary Understanding how life history shapes genetic diversity is a fundamental issue in evolutionary biology, with important consequences for conservation. However, we still have an incomplete picture of the impact of life history on genome‐wide patterns of diversity, especially in long‐lived semelparous plants.

Genetic markers in Andean Puya species (Bromeliaceae) with implications on plastome evolution and phylogeny. [PDF]
Ecol Evol, 2022 Comparative analyses revealed plastome features, genomic evolution, divergence time, and phylogenetic relationships of the genus Puya. Plastomes have great potential for phylogenetic recontraction and species discrimination of Puya. Abstract The Andean plant endemic Puya is a striking example of recent and rapid diversification from central Chile to ...

Estructura y Diversidad Genética de Puya raimondii Harms “El gigante de los Andes Peruanos” [PDF]
, 2021 En los Andes del Perú habita Puya raimondii donde se encontraron diferencias morfológicas (morfotipos) en las poblaciones, motivo que ha impulsado al desarrollo de marcadores microsatélites específicos para la especie. El objetivo de la investigación fue evaluar la diversidad genética y estructura genética de las poblaciones de Choconchaca (Puno ...

Ecosystem services provided by bromeliad plants: A systematic review. [PDF]
Ecol Evol, 2019 Bromeliads have been widely used as a model system for testing fundamental ecological theory; nevertheless, their benefits to the surrounding ecosystems and human society have been largely overlooked. Using a systematic review, we showed that while the publication of studies about supporting ecosystem services have accelerated over the last 30 years ...

'Chimes of resilience': what makes forest trees genetically resilient? [PDF]
New PhytolSummary Forest trees are foundation species of many ecosystems and are challenged by global environmental changes. We assemble genetic facts and arguments supporting or undermining resilient responses of forest trees to those changes. Genetic resilience is understood here as the capacity of a species to restore its adaptive potential following ...

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