We report on Gomphrena fuscipellita T. Ortuño & Borsch, a species endemic to Bolivia’s dry valleys. This was initially described from type specimen collected in 2005 Cochabamba (Mizque Province) and an additional sample Potosí (Charcas Province). However, after two decades, the has been documented further across southern Bolivia. study provides updated geographical distribution, micro‑morphological trichome descriptions, ecological insights that...
To examine the climate of mid-Holocene and early human settings in Andes when Altiplano was recording most arid phase Holocene, we analyzed plant-related proxies (pollen, phytoliths, diatoms, stable isotopes) from a sediment core sampled at high elevation Eastern Cordillera Bolivia. Our study carried out wetland Tiquimani (16°12′06.8″S; 68°3′51.5″W; 3760 m), on well-known pathway between Amazonia Altiplano. The 7000-year old record shows two-step with dry 6800 5800, followed by wetter period...
Abstract Question: What is the effect of shrubs on herbaceous species richness at three spatial scales: quadrat, site, and region? Location: Prepuna, subtropical semi‐arid Andes. Methods: At eight sites, we recorded presence in spaces beneath shrubs/small trees open areas. quadrat scale, average number per was calculated compared between two microhabitats (shrubs/open). local (site) all quadrats each site were pooled according to microhabitat, sites then combined for regional analysis....
Changes in climate conditions during the Holocene are documented different parts of South America, showing contrasting responses to global changes. This study was conducted wet puna at an elevation 4040 m a.s.l. on eastern side Cordillera Real Bolivia near Lake Titicaca. Pollen, charcoal, and stable isotopes a sediment core collected peatland Escalerani were analyzed. Results revealed environmental changes past 7500 yr BP, with increase from 5900 4700 cal. BP 3500 1300 two dry periods...
Abstract— Gomphrena meyeniana is an extremely variable species from the Andean highlands, which has attracted attention of many botanists because it world’s highest-elevation C 4 eudicot and its wide morphological variability. It typical high-Andean plant morphology, with small leaves tightly clustered on a thick rootstock. The large range variation within this coupled varying opinions existence several or infra-specific taxa lack molecular information made clarification G. complex...
La misión franco-boliviana «Paleoambiente y Arqueología del río Guaquira-Tiwanaku» intenta restituir la evolución paisaje al contacto de una las culturas más emblemáticas los Andes. cultura Tiwanakota se desarrolló en orillas Lago Titicaca final segundo milenio antes nuestra era desapareció entre 1100 1200 d. C. tras sequía que afectó el conjunto Altiplano. Presentamos aquí metodología trabajos curso cuenca hidrográfica permitirán entender mejor interacciones medioambiente inmediato sitio...
Abstract Our study is located in northern Beni and aims to improve knowledge on regional landscape changes from the last 8600 years, based pollen charcoal analyses a lacustrine sediment core Lake Ginebra. results showed that gallery forest were observed 8645 until 3360 cal yr BP. After change swamp environment at 1700 BP, Cerrados Mauritia became installed 1000 years ago our site. The environmental we over Ginebra record reinforce evidence of west–east climatic gradient with persistence rain...
In the present study we revised genus Hypseocharis in Bolivia and Peru. A total number of 105 herbarium specimens were to evaluate morphological diversity across range genus. a subset 24 complete individuals multivariate morphometric analysis was performed characters historically used differentiate “species” Hypseocharis. revision material indicated that there are no sharp lines dividing different with only exception H. tridentata. The bilobata, malpasensis pedicularifolia all occupy same...
