Rizospheric Microbiota of Espeletia spp. from Santa Inés and Frontino-Urrao Paramos in Antioquia, Colombia

open access: yesActa Biológica Colombiana, 2015
The frailejón (Espeletia spp.) is the emblematic shrub of the paramo. This is an important ecosystem because they are sources of water and organic matter, and are inhabited by a high number of endemic biological species. Considering the importance of the

Global variability in hydraulic traits and water use strategies of mountain shrubs and dwarf shrubs. [PDF]

open access: yesPlant Biol (Stuttg)
Shrubs show a wide range of hydraulic strategies to achieve a balanced and favourable water status in mountain areas. Abstract Shrubs are perennial, multi‐stemmed woody plants whose adaptation to stress factors allows them to colonise extreme habitats, including high elevations. Accordingly, shrubs are one of the most important growth forms in mountain

Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems. [PDF]

open access: yesEcol Evol
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Diversity of insects associated with Espeletia spp. in the Chingaza páramo (Colombia) and their agroecosystem relevance

open access: yesCiencia y Agricultura
The Chingaza paramo is a strategic ecosystem with high entomological richness, where plant-insect interactions often mediated by chemical signals are fundamental to ecological balance.

The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae). [PDF]

open access: yesNew Phytol, 2016
Summary The tropical Andes of South America, the world's richest biodiversity hotspot, are home to many rapid radiations. While geological, climatic, and ecological processes collectively explain such radiations, their relative contributions are seldom examined within a single clade.

An empirical assessment of a single family-wide hybrid capture locus set at multiple evolutionary timescales in Asteraceae. [PDF]

open access: yesAppl Plant Sci, 2019
Premise Hybrid capture with high‐throughput sequencing (Hyb‐Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family‐specific Hyb‐Seq probe set and the outcomes of different phylogenetic analyses are investigated here.

Measurement of actual evapotranspiration in a páramo ecosystem using portable closed chambers: Comparison between giant rosettes, tussock grasses and shrubs

open access: yesEcohydrology, Volume 16, Issue 4, June 2023., 2023
Abstract The páramos are Neotropical alpine tundra‐like ecosystems that play a crucial role as biodiversity hotspots and also act as water sources for the inter‐Andean regions and cities. Improving our understanding of hydrological processes, here evapotranspiration, is crucial, especially in the context of global changes.

The best of two worlds: ecology and evolution of ambophilous plants

open access: yesBiological Reviews, Volume 98, Issue 2, Page 391-420, April 2023., 2023
ABSTRACT Ambophily, the mixed mode of wind and insect pollination is still poorly understood, even though it has been known to science for over 130 years. While its presence has been repeatedly inferred, experimental data remain regrettably rare. No specific suite of morphological or ecological characteristics has yet been identified for ambophilous ...
