We present here to Maxillaria jostii Dodson (Orchidaceae) a new addition to the angiosperm Flora of Peru from sandstone substrate of the Sub-Andean Cordillera de Huarango (province of San Ignacio, department of Cajamarca), a southern prolongation to the very biodiverse Cordillera del Condor. Maxillaria jostiihas been formerly considered a species endemic to southern Ecuador (Zamora-Chinchipe, Morona-Santiago), but with the present study extends its geographical distribution range to northern Peru. This new contribution to the knowledge of the Flora of Peru is the result of a combined fieldwork and herbarium effort, thanks to Binational Project named “Botanical Inventory of the Cordillera del Condor Region of Ecuador and Peru, 2005-2007" and developed by the following scientific institutions: MO, HUT, LOJA and QCNE. The species reported here was compared against the list of species docu...

Se presenta a Maxillaria jostii Dodson (Orchidaceae) como una nueva adición a la Flora del Perú procedente de los substratos de roca arenisca de la Cordillera subandina de Huarango (provincia San Ignacio, departamento Cajamarca), una prolongación sureña de la Cordillera del Cóndor rica en especies. Maxillaria jostii ha sido considerada como una especie endémica para Ecuador (Zamora-Chinchipe, Morona-Santiago); sin embargo, con el presente estudio se amplía su distribución geográfica hacia el Perú. Esta nueva contribución al conocimiento de la flora del país es el resultado del trabajo de campo y de herbario, gracias al Proyecto Binacional «Inventario Botánico de la Región de la Cordillera del Cóndor, Ecuador y Perú, 2005-2007», desarrollado entre las instituciones: MO, HUT, LOJA y QCNE. La contrastación específica se realizó con las especies documentadas en el «Cat...

Between 2000 and 2016 we carried out 15 rapid biological inventories in remote areas of the Andean foothills and Amazon basin in Peru. During these inventories, 27 botanists collected 9397 fertile vascular plant specimens. By the end of 2017, more than half of these specimens had been identified to species. Of the 2303 species identified to date, 64 species and 2 genera (Dicorynia and Monopteryx) are new records for the flora of Peru. If this rate of discovery proves typical, the number of new records for Peru in the rapid inventory material could increase, which indicates that there is still much to discover in the Peruvian flora.

Los bosques amazónicos son ecosistemas sensibles al fuego y, en consecuencia, los incendios afectan a la estructura y composición del bosque. Por ejemplo, el vestigio de los incendios pasados puede persistir a través de algunas especies y rasgos que se encuentran debido a los fuegos históricos. En este estudio se comprueban las relaciones entre los rasgos funcionales que se presentan clásicamente como los principales componentes de las estrategias ecológicas de las plantas y los filtradores ambientales relacionadas con el clima y los incendios históricos entre las parcelas de bosque maduro permanente a lo largo del rango de gradientes ambientales locales y regionales que se dan en la Amazonia. Se utilizó el porcentaje de carbono pirogénico superficial del suelo (PyC), una forma recalcitrante de carbono que puede persistir durante milenios en los suelos, como un nuevo indicador d...

Within the tropics, the species richness of tree communities is strongly and positively associated with precipitation. Previous research has suggested that this macroecological pattern is driven by the negative effect of water‐stress on the physiological processes of most tree species. This implies that the range limits of taxa are defined by their ability to occur under dry conditions, and thus in terms of species distributions predicts a nested pattern of taxa distribution from wet to dry areas. However, this ‘dry‐tolerance’ hypothesis has yet to be adequately tested at large spatial and taxonomic scales. Here, using a dataset of 531 inventory plots of closed canopy forest distributed across the western Neotropics we investigated how precipitation, evaluated both as mean annual precipitation and as the maximum climatological water deficit, influences the distribution of tropica...
