Commodity risk assessment of Ullucus tuberosus tubers from Peru. [PDF]

open access: yesEFSA J, 2021
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects. This Scientific Opinion covers plant health risks posed by tubers of Ullucus tuberosus imported from Peru ...

Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes. [PDF]

open access: yesAm J Bot
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Ampliación de la distribución geográfica y estado de conservación de Ctenoblepharys adspersa (Tschudi, 1845)

open access: yesRevista Peruana de Biología, 2021
Ampliamos la distribución geográfica de Ctenoblepharys adspersa (Liolaemidae), una especie de saurio endémico y amenazado del desierto peruano. Nuestro nuevo registro extiende la distribucion de esta especie en 60 km (línea recta) de la localidad más ...

A target enrichment probe set for resolving phylogenetic relationships in the coffee family, Rubiaceae

open access: yesApplications in Plant Sciences, Volume 11, Issue 6, November-December 2023., 2023
Abstract Premise Rubiaceae is among the most species‐rich plant families, as well as one of the most morphologically and geographically diverse. Currently available phylogenies have mostly relied on few genomic and plastid loci, as opposed to large‐scale genomic data.

Calceolariaceae809: A bait set for targeted sequencing of nuclear loci

open access: yesApplications in Plant Sciences, Volume 11, Issue 6, November-December 2023., 2023
Abstract Premise The genus Calceolaria (Calceolariaceae) is emblematic of the Andes, is hypothesized to have originated as a recent, rapid radiation, and has important taxonomic needs. Additionally, the genus is a model for the study of specialized pollination systems, as its flowers are nectarless and many offer floral oils as a pollination reward ...

Ecological convergence in phytochemistry and flower–insect visitor interactions along an Andean elevation gradient

open access: yesEcology and Evolution, Volume 13, Issue 8, August 2023., 2023
In this study, we detected patterns of ecological convergence along elevation in floral volatiles as well as cost–benefit ratio in seed versus pollinated seeds. Our results suggest that these evolutionary patterns are the result of biotic and abiotic pressures.

Neutral‐based processes overrule niche‐based processes in shaping tropical montane orchid communities across spatial scales

open access: yesJournal of Ecology, Volume 111, Issue 8, Page 1614-1628, August 2023., 2023
High compositional turnover, even across habitats with the highest degree of human intervention, suggests that both forest‐dwelling and open‐habitat species do not easily disperse across habitats. Species dispersal is the major force of orchid community turnover and might be strongly dependent upon macroevolutionary processes and species life‐history ...

Disentangling microstructure and environmental conditions in high‐altitude Andean microbialite systems (Catamarca, Argentine Puna)

open access: yesEnvironmental Microbiology Reports, Volume 15, Issue 2, Page 92-108, April 2023., 2023
Abstract The study of microbialites development is a key tool to understand environmental pathways during deposition. We provide a detailed analysis of modern Central Andean microbialites from high‐altitude lakes. The stratigraphic record of Turquesa Lake shows a significant short‐term recolonization by microbialite‐producing microorganisms during ...

Mycorrhizal science outreach: Scope of action and available resources in the face of global change

open access: yesPLANTS, PEOPLE, PLANET, Volume 3, Issue 5, Page 506-522, September 2021., 2021
Mycorrhizal associations are acknowledged as key components of global ecosystem functioning. This is especially relevant in the context of global change, since they contribute to the amelioration of adverse soil conditions and play crucial roles in agriculture.

One species with a disjunct distribution or two with convergent evolution? Taxonomy of two South American garlics

open access: yesTAXON, Volume 70, Issue 4, Page 842-853, August 2021., 2021
Abstract The establishment of species boundaries has been a difficult task for biologists since the beginning of classifications. Within South American Allioideae (= Alliaceae), the delimitation of genera and species has long been a major challenge. Consequently, species‐level nomenclature in these groups has been difficult to elucidate.
