“…Finalmente, la presencia de individuos adultos que apor tan cober tura y hojarasca son amenazados usualmente por acciones antrópicas (incendios, ganadería, cor ta de individuos, urbanización) (Sotes et al 2006). La extracción de hojarasca para horticultura y jar dinería, práctica habitual por las comunidades humanas locales en el matorral de Chile central (Lienlaf 1996), también representa una amenaza para esta especie y probablemente para otras presentes en esta zona.…”

ARTÍCULO DE INVESTIGACIÓN RESUMENPouteria splendens (lúcumo chileno, palo colorado) es un árbol endémico de Chile central con problemas de conservación. Es la única especie representante de la familia Sapotaceae en el país y se conoce muy poco de su ciclo de vida. En este trabajo describimos el patrón de distribución espacial de plántulas en la población remanente de mayor tamaño de la especie, e investigamos el efecto de la disponibilidad de agua, la presencia de pericarpo en las semillas y de la hojarasca en la capacidad de germinación. La densidad de plántulas fue mayor bajo el dosel de las plantas madres, que fuera de estas. Solo la disponibilidad de agua tuvo un efecto signifi cativo sobre la germinación. La especie tiene el potencial de regenerar, en futuros planes de conservación y restauración de la especie hay que aprovechar el efecto nodriza que estaría ejerciendo el dosel.Palabras clave: árbol endémico, dosel, especie amenazada, hojarasca, pericarpo. ABSTRACTPouteria splendens (Chilean lúcumo, red wood) is an endemic and endangered tree from Central Chile. It is the only member of the Sapotaceae family in the country and little is known about his life cycle. In this work we described the spatial distribution of seedlings in the biggest remained population of the species, and we investigated the effect of the water availability, presence of pericarp in the seeds and the leaf litter on the capacity of germination in the species. Seedling density was higher under the canopy of mother plants, than outside its. Only water availability had a signifi cant effect on the germination. The species has the potential to regenerate, in future plans of conservation and restoration of the species must take advantage the nurse effect of the canopy.

RESUMO: "Gênero Pouteria: Química e atividade biológica". O gênero Pouteria pertence à família Sapotaceae e pode ser encontrado em muitos continentes. As plantas desse gênero têm sido utilizadas na construção civil, na alimentação e também na medicina popular. Algumas atividades biológicas são reportadas às espécies desse gênero, tais como, antioxidante, anti-inflamatória, antibacteriana e antifúngica, mas seu real potencial como fonte de novos fármacos ainda é pouco conhecido. Assim, uma revisão sobre a composição química e as atividades biológicas de Pouteria é apresentada, com o intuito de estimular a continuação dos estudos das espécies aqui citadas, e a investigação de outras espécies para as quais não foram encontrados relatos.Unitermos: Pouteria, Sapotaceae, triterpenos, flavonoides, plantas medicinais. ABSTRACT:The genus Pouteria belongs to the family Sapotaceae and can be widely found around the World. These plants have been used as building material, as food, because the eatable fruits, as well as remedies in folk medicine. Some biological activities have been reported to species of this genus such as antioxidant, anti-inflammatory, antibacterial and antifungal. However, the real potential of this genus as source of new drugs or phytomedicines remains unknown. Therefore, a review of the so far known chemical composition and biological activities of this genus is presented to stimulate new studies about the species already reported moreover that species have no reference about chemistry or biological activities could be found until now.

“…The few studies available for P. splendens have been focused in understanding the species autoecology (i.e., Sotes et al 2006; Nuñez et al 2009; Henríquez et al 2012; Sotes et al 2013), and until now there have been no studies at larger scales that may provide answers to the original metapopulation hypothesis. This lack of information is not only limiting our understanding about potential causes of the current fragmented distribution of P. splendens populations, but also our ability to gauge the urgency to develop conservation efforts.…”

21Background: Pouteria splendens (lúcumo chileno) is an endemic shrub to the coastal areas 22 of Central Chile classified as Endangered and Rare by the Chilean threatened species list, 23 but as Lower Risk (LR) by IUCN. Based in historical records some authors have 24 hypothesized that P. splendens originally formed a large metapopulation, but due to habitat 25 loss and fragmentation these populations have been reduced to two main areas separated by 26 100 km, neither of both currently protected by the Chilean system of protected areas. 27Knowledge about this species is scarce and no studies have provided evidence to support 28 the large metapopulation hypothesis. This gap of knowledge limits our availability to gauge 29 the real urgency to conserve remaining P. splendens populations, which can generate tragic 30 consequences in light of the increasing land-use change and climatic change that are facing 31 these populations. In this study we combined niche modelling, land-use information, future 32 climatic scenarios, and conservation genetics techniques, to test the hypothesis of a 33 potential original large metapopulation, evaluate the role of land-use change in population 34 decline, assess the threats this species may face in the future, and combine the generated 35 information to re-assess its conservation status using the IUCN criteria. 36Results: Our results show that locations with P. splendens are fewer than described in the 37 literature. Results from the niche modelling and genetic analyses support the hypothesis of 38 an originally large metapopulation that was recently reduced and fragmented by 39 anthropogenic land-use change. Future climate change could increase the range of suitable 40 habitats for P. splendens towards inland areas; however the high level of fragmentation of 41 these new areas is expected to preclude colonization processes. 42Conclusions: Based on our results we recommend urgent actions towards the conservation 43 of this species, including (1) re-evaluating its current IUCN conservation status and 44 reclassifying it as Endangered (EN), and (2) take immediate actions to develop strategies 45 that effectively protect the remaining populations. 46 47
