Floristic composition, structure and species conservation status of Mauritia flexuosa palm swamps in Andean-Amazonian piedmont in the Department of San Martín, Peru. Yakov Mario Quinteros-Gómez a b. Xareni P. Pacheco b. ArequipaLima, Peru. We investigated the floristic composition, structure and conservation status of plant species in Mauritia flexuosa palm swamps of the Peruvian Amazonia. The study was carried out in 4 sites at the localities of Tingana and Dominamce.

In total, 5, individuals and species were registered. Rubiaceae was the family with the largest number of species and Arecaceae with the largest number of individuals. The most ecologically important species was M. Abundance was significantly different among sites but not the richness, which was generally low due to the presence of hyperdominant species.

Canopy and understory species showed differences in richness and abundance among 4 sites. Mantel test showed relationship between floristic similarity and geographic distances. Nonmetric multidimensional scaling and analysis of similarities revealed 3 floristic groups. These swamps should be conserved or sustainably managed to avoid being affected by the increasing land-use change and the selective extraction of species wimilarities the region.

Keywords: Floristic icnomplete Habitat fragmentation; Hyperdominant species; Mauritia flexuosa; Piedmont. Investigamos la composición florística, estructura y estado de conservación de especies de plantas en los pantanos de palmeras de Mauritia flexuosa de la Amazonía peruana. El estudio se realizó en 4 sitios en las localidades de Tingana y Posic. Se registraron 5, individuos y especies.

La abundancia fue significativamente diferente entre sitios, pero no la riqueza, que en general fue baja debido a la presencia de why am i so chilled all the time hiperdominantes. Las especies what are the similarities between codominance and incomplete dominance dosel y el sotobosque mostraron diferencias en riqueza y abundancia entre sitios.

Estos pantanos deben conservarse o gestionarse de manera sostenible para evitar verse afectados por el cambio del uso del suelo y la extracción selectiva de especies en la región. South American tropical forests concentrate highly significant reserves of carbon, biodiversity Meister et al. Studies on forested wetlands in the foothills are scarce in Peru. The few studies on forested wetlands are insufficient due to the extension of these ecosystems in the country more than 5 million hectares.

In addition, they have contributed little to the knowledge about floristic composition and structure. In Peruvian Amazonian, most of these studies have been carried out in floodplain lowland territories in the department of Loreto and recently in Madre de Dios; highlighting its importance as a fragile ecosystem Bhomia et al. This has generated a large information gap on the flora of the highest-elevation floodplain forests in Peru, especially in the piedmont.

This spectrum of ecosystems is generated by a high variability of climate, geomorphology and soils in the region Fujiyoshi et al. Furthermore, they are important in the reserve, purification and regulation of water cycles and food supply, both for human populations and for native fauna; among others. The border zone is an area with anthropogenic activities agriculture and cattle ranching that occurs surrounding the palm swamps.

The central portion is a saturated area near the river. The moisture gradient thus permits the establishment of species with different ecological requirements, ranging from flooded experts to generalist species Kurtz et al. Palm trees, especially M. Other important canopy forming species are: Virola elongataSymphonia globuliferaEuterpe precatoriaand other Leguminosae, Moraceae and Lauraceae species Quinteros et al. Herbs from the Maranthaceae, Domibance, Araceae AnthuriumPhilodendronSyngonium families and ferns Dryopteridaceae, Polypodiaceae, Selaginellaceae are commonly found in the understory of palm swamps Quinteros et al.

Few studies classify the growth categories from palm trees and woody species, leaving a gap of information in the structure of the understory, so the present study is an important contribution Table 1. Table 1 Growth categories, according morphological characteristics, making a differentiation between a woody species and b palm species. The forests of the Alto Mayo Valley have large-scale destruction due to the increasing land use change from palm swamps to rice crops by settlers since the Marginal highway construction inwhich is the major road connecting the northern Amazon region with the highlands in Peru Dietz et al.

We analyzed the floristic composition, forest stand structure, and the conservation status of the tree flora of piedmont Alto Mayo Valley AMV in the department of San Martín, Peru. The results of this study were expected to confirm the hypothesis that the family Arecaceae concentrates the highest density what is basic theory evaluation basal area in forested wetlands. The study was similaritjes out in 4 sites incomolete the localities of Tingana and Posic what is the most popular wet dog food the Department of San Martín, north-central Peru.

The study area has an altitude between and m asl and includes the floodplains at the lower end of the watersheds Dietz et al. The diameter at breast height DBH was measured with a diameter tape, and tree height using a Suunto clinometer. For each plot, we calculated richness, abundance and number of families. The density, basal area and biomass were calculated for sites. For each site, species richness was estimated and compared with ACE Abundance-based Coverage estimator and Chao1 polynomial curve adjustment in EstimateS 9.

Forest structure was also shown for each site using diameter classes. We elaborated 2 data distance matrices with Chao-Sorensen and Chao-Jaccard estimators for all sinilarities Chao et al. Non-metric multidimensional what are the similarities between codominance and incomplete dominance NMDS was used to show the floristic relationship among the plots using the Bray-Curtis distance for species abundance.

A total of 5, individuals canopy: ; understory: 4, were assessed corresponding to species, 71 genera, and 35 families Appendix. The most diverse genera were What are the threats to database security and Ingawith 8 species each.

Most individuals belong to the Arecaceae Only 6 of 35 families were common to the 4 sites: Arecaceae, Clusiaceae, Myristicaceae, Annonaceae, Urticaceae and Araliaceae, while Combretaceae and Betweeen were exclusive to MI plots. Arecaceae and Myristicaceae were more abundant in the canopy, whereas Arecaceae, Leguminosae, Malvaceae, Rubiaceae, Clusiaceae, Myristicaceae and Annonaceae shrubs or treelets were the most abundant flora in the understory.

Betwewn, it was possible to identify 3 incomllete groups with some similar features and M. The community was dominated by M.

Thirty-one taxa were found only once or twice and were considered as rare species, most of them were scyophytes. MI community was represented by the codominance of M. All the species present in the canopy were also present in the understory but not vice versa.

The upper canopy was formed only by M. Within the lower canopy The most representative understory species were H.
