Ecophysiological Analysis Of Drought And Salinity Stress Of Quinoa (<i>Chenopodium Quinoa</i>willd.)
(Taylor & Francis, 2003) H. Bosque Sanchez; Raoul Lemeur; Patrick Van Damme; Sven‐Erik Jacobsen
Abstract We assessed the relative influence of drought or salinity stress with similar soil water potentials on growth, plant water relations, and photosynthesis rate of Chenopodium quinoaWilld., as well as the suitability of common techniques used in stress physiology studies. Our results from greenhouse pot experiments showed that salt stress induced better absolute and relative growth rates, and that the plant developed adaptation mechanisms to drought through high water use efficiency and high root shoot ratios. The stomatal resistance and the leaf water potential increased with an increased stress level. Variable to maximal chlorophyll fluorescence (Fv/Fm) and quenching analysis (qP and qN) showed that dehydrated plants are less protected from photoinhibition. The dynamic diffusion porometer is of limited use in leaves with salt glands. #Master of Science thesis. Article submitted to the First International Workshop of Quinoa. 10-14 May, 1999. Lima, Peru.

<i>Susto</i> Etiology and Treatment According to Bolivian Trinitario People:
(Wiley, 2009) Evert Thomas; Ina Vandebroek; Patrick Van Damme; Lucio Semo; Zacaria Noza
This article addresses two concepts that are quite widespread among Latin American cultures: susto or "'fright sickness," and the "masters of the animal species" philosophy, whereby individual animal spirits are believed to be "owned" by species-specific spiritual masters. This is the first article to integrate both these aspects, drawing from ethnographic data from the Trinitario people in Bolivia collected through participant-observation and semistructured ethnobotanical interviews on medicinal plants. Although Trinitarios have a long history of agriculture, their worldview is still partly one of animistic hunter and fisherman societies. This worldview is reflected in Trinitario susto etiology and treatment. Susto is locally believed to originate through soul theft by a variety of masters of the animal species and landscape spirits. Treatment is partly based on the principle of similia similibus curantur or "like cures like" and magicoritual ceremonies, but ethnopharmacological preparations are also well known and frequently used.
Mapping Genetic Diversity of Cherimoya (Annona cherimola Mill.): Application of Spatial Analysis for Conservation and Use of Plant Genetic Resources

There is a growing call for inventories that evaluate geographic patterns in diversity of plant genetic resources maintained on farm and in species' natural populations in order to enhance their use and conservation. Such evaluations are relevant for useful tropical and subtropical tree species, as many of these species are still undomesticated, or in incipient stages of domestication and local populations can offer yet-unknown traits of high value to further domestication. For many outcrossing species, such as most trees, inbreeding depression can be an issue, and genetic diversity is important to sustain local production. Diversity is also crucial for species to adapt to environmental changes. This paper explores the possibilities of incorporating molecular marker data into Geographic Information Systems (GIS) to allow visualization and better understanding of spatial patterns of genetic diversity as a key input to optimize conservation and use of plant genetic resources, based on a case study of cherimoya (Annona cherimola Mill.), a Neotropical fruit tree species. We present spatial analyses to (1) improve the understanding of spatial distribution of genetic diversity of cherimoya natural stands and cultivated trees in Ecuador, Bolivia and Peru based on microsatellite molecular markers (SSRs); and (2) formulate optimal conservation strategies by revealing priority areas for in situ conservation, and identifying existing diversity gaps in ex situ collections. We found high levels of allelic richness, locally common alleles and expected heterozygosity in cherimoya's putative centre of origin, southern Ecuador and northern Peru, whereas levels of diversity in southern Peru and especially in Bolivia were significantly lower. The application of GIS on a large microsatellite dataset allows a more detailed prioritization of areas for in situ conservation and targeted collection across the Andean distribution range of cherimoya than previous studies could do, i.e. at province and department level in Ecuador and Peru, respectively.
Passiflora venusta, a New Species of Passiflora series Laurifoliae (Passifloraceae) from Bolivia
(Missouri Botanical Garden Press, 2007) Roberto Vásquez; Marleen Delanoy; Xavier Scheldeman; Patrick Van Damme; Stephan Beck
Passiflora venusta R. Vásquez & M. Delanoy, a new species of subgenus Passiflora L. ser. Laurifoliae Killip ex Cervi (Passifloraceae) is described and illustrated. Passiflora venusta differs from the other species belonging to this series by a unique combination of characteristics: flowers are large (ca. 12 cm diam.) and solitary; sepals and petals are white outside and red-purple inside; outside, sepal veins are white whereas petal veins are red; corona filaments are long and the outermost rank of filaments is noticeably shorter and thinner than the second rank; and fruits are 3.9–5.9 cm long with an endocarp no more than 0.5 cm thick.

The cultural importance of traditional medicine and the physical isolation of communities, both in general and from PHCs, are factors that influence the use of and knowledge about medicinal plants.
