Genotyping-by-sequencing informs conservation of Andean palms sources of non-timber forest products. [PDF]

Evol Appl
Abstract Conservation and sustainable management of lineages providing non‐timber forest products are imperative under the current global biodiversity loss. Most non‐timber forest species, however, lack genomic studies that characterize their intraspecific variation and evolutionary history, which inform species' conservation practices.

Evaluation of a compounding phospholipid base for the percutaneous absorption of high molecular weight drugs using the Franz finite dose model.

Skin Res Technol
Abstract Background Permeation‐enhancing compounding bases are aimed to facilitate the penetration of the active pharmaceutical ingredients (APIs) across the skin barrier. Objectives The purpose of this study was to evaluate the percutaneous absorption of radiolabeled human insulin (14C‐isototpe) when incorporated in a proprietary phospholipid base ...

Pollination ecology in the tropical Andes: moving towards a cross-scale approach. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

The fate and transit time of carbon in a tropical forest

Journal of Ecology, Volume 109, Issue 8, Page 2845-2855, August 2021., 2021
The transit time distribution quantifies the time it takes for photosynthates to appear in the respiration flux. For a tropical forest in Colombia, it predicts that 50% of fixed carbon is respired in <0.5 years, and 95% in <69 years. Editor's Choice Abstract Tropical forests fix large quantities of carbon from the atmosphere every year; however, the ...

Shading and controlled-release fertilizer in the production of Oenocarpus bataua Mart. Seedlings

Comunicata Scientiae, 2023
When associated an adequate shading and nutrition the seedlings to reach characteristics that allow them tosurvive in the field and increase production. Thus, this work aimed to evaluate the production of Oenocarpusbataua seedlings in response to different shade environments and controlled-release fertilizer doses.

Useful palms (Arecaceae) near Iquitos, Peruvian Amazon

Revista Peruana de Biología, 2014
This paper describes the uses of 64 species of palms in 28 villages in Departamento de Loreto, Peru. There, the palms are of great use as food (Bactris gasipaes, Mauritia flexuosa, Euterpe precatoria, Oenocarpus bataua), for fiber production ...

Pleistocene climatic fluctuations promoted alternative evolutionary histories in Phytelephas aequatorialis, an endemic palm from western Ecuador

Journal of Biogeography, Volume 48, Issue 5, Page 1023-1037, May 2021., 2021
Abstract Aim Pleistocene (2.58 Ma–11.7 ka) climatic fluctuations have shaped intraspecific genetic patterns worldwide; however, their impact on species in many regions remains unknown. In order to determine the impact of Pleistocene climatic fluctuations on the tropical rain forests of western Ecuador, we explored the evolutionary history of the ...

Defaunation Increases Clustering and Fine-Scale Spatial Genetic Structure in a Small-Seeded Palm Despite Remaining Small-Bodied Frugivores. [PDF]

Mol Ecol
ABSTRACT Anthropogenic pressures such as hunting are increasingly driving the localised functional extinctions of large‐ and medium‐sized wildlife in tropical forests, a phenomenon broadly termed ‘defaunation’. Concurrently in these areas, smaller‐bodied species benefit from factors such as competitive release and increase in numbers.

Trophic relationships between palms and bruchids (Coleoptera: Bruchidae: Pachymerini) in Peruvian Amazonia [PDF]

, 1995
Qualitative and quantitative host plant data are provided for palm bruchids in a part of Amazonia from where previously few or no data were available. The host range and geographical distribution of several species are extended.

Modeling the stipe growth of the Oenocarpus bataua palm in the Central Cordillera of the Andes, Colombia [PDF]

Forest Ecology and Management, 2014
Abstract Over 9.4 years in the premontane natural forest of Colombia, we measured the annual rates of growth in length (RGL) of the stipes, the stipe length (l) and the annual rates of leaf scars (RLS) in 109 palms of Oenocarpus bataua. We counted leaf scars on the stipes and the leaves of the crown of each palm (SPL) and determined the position of ...
