Abstract. Given the short span of instrumental precipitation records in South American Altiplano, longer-term hydroclimatic are needed to understand nature climate variability and improve predictability precipitation, a key natural resource for socioeconomic development Altiplano adjacent arid lowlands. In this region grows Polylepis tarapacana, long-lived tree species that is very sensitive changes has been widely used tree-ring studies central southern Altiplano. However, northern sector...
Abstract Cedrela species occur within the Tropical montane cloud forest (TMCF) and rainforest in North America (Mexico), Central South America. We assessed hypothesis that functional xylem hydraulic architecture might be influenced by specific climatic variations. investigated effect of climate on tree-ring width vessel traits (diameter, density, vulnerability index diameter) three relict-endemic threatened ( fissilis , C . nebulosa angustifolia ) inhabiting Peruvian Andean forests. All...
Abstract Almost half of the tributaries Amazon River originate in tropical Andes and support large populations mountain regions downstream areas. However, it is difficult to assess hydroclimatic conditions or evaluate future scenarios due scarcity long, high‐quality instrumental records. Data from Global Precipitation Climatology Project (GPCP) provide a complete record since 1979 offer good representation rainfall over Andes. Longer records are needed improve our understanding variability...
Summary Andean Walnut ( Juglans neotropica Diels-Juglandaceae) is a long-lived, deciduous broadleaf Tropical Montane Cloud Forest (TMCF) tree species native to the Andes Cordillera; nevertheless, it has received limited attention for dendro-quantitative wood anatomical studies. Based on 70 increment cores from 50 trees at two Peruvian TMCFs, chronologies (from 1969 2020 and 1964 2020) were developed. The xylem vessel parameters assessment allowed us detect South American Monsoon System...
There is a significant dendrochronological gap in the Puna of central Andes Peru, which motivates research on new species. In this study, we present first tree-ring chronologies Escallonia myrtilloides. We collected samples at San Pedro Saño and Sapallanga analyzed anatomical characteristics that delimit annual growth rings, developed two through conventional techniques. The cover period 1940–2015 (76 years) for 1960–2015 (56 Sapallanga. E. myrtilloides presented similar values mean...
In the tropical Andes climate change is expected to increase temperatures and precipitation patterns. To overcome lack of systematic weather records that limits performance models in this region, use environmental information contained tree rings from Andean species have been found useful reconstruct spatio-temporal variability. Because classical dendrochronology based on ring-width patterns often challenging tropics, alternative approaches such as Quantitative Wood Anatomy (QWA) measurement...
The impact of drought on vessel architecture and function has been broadly assessed for a variety tree species in the last decades, but hydraulic plasticity under temperature increase scarcely studied. effect tree-ring width specific conductivity depends relict-tree resilience to climatic adaptability its wood anatomical responses oscillations. We adaptation two threatened Peruvian Andean Polylepis (P. rodolfo-vasquezii P. tarapacana). found that historical years differentially affected...
Descrevemos os resultados do estudo da profundidade ótica aerossol (POA) e Forçamento Radiativo Direto (FRD) no topo atmosfera (TOA), obtidos durante a campanha de medição monitoramento, XXI Expedição Antártica Peru, entre meses janeiro fevereiro 2013, na área metropolitana Huancayo (AMH) junho julho 2019. Na Estação Peruana Machu Picchu utilizou-se um fotômetro solar SP02-L. Tal instrumento possui 4 canais: 412 nm, 500 675 nm 862 permitindo realizar medições diretas espectro radiação...
