Introduction
Cecilia Blundo currently works at the Instituto de Ecología Regional (IER) - CONICET, National University of Tucuman. Cecilia does research in Forest Ecology. Their current project is: Forest dynamics in subtropical Andes: influences of climate and forest use. She collaborates with the maintenance of a network of 73 permanent plots established between 300 and 2300 m asl in NW Argentina (22-27° S). This database is the main input in your current work.

R������. Las parcelas forestales permanentes son áreas de muestreo donde se registran periódicamente la identidad, abundancia y tamaño de los árboles, para estudiar cómo cambian los bosques en relación con el clima, los disturbios naturales y los usos y manejos. Hasta hoy, los patrones de cambio observados con parcelas permanentes en la Argentina t...
Article
Data on tropical forests are in high demand. But ground forest measurements are hard to sustain and the people who make them are extremely disadvantaged compared to those who use them. We propose a new approach to forest data that focuses on the needs of data originators, and ensures users and funders contribute properly.

Most studies on forest transition (FT) have focused on temporal patterns of forest cover across whole countries or regions, without much consideration of the local spatio-temporal heterogeneity or the species composition of new forests. We hypothesize that peri-urban forest transitions are driven by processes associated with urban-based economies a...

High Andean vegas are key functional wetlands in the Puna ecoregion. Plant communities in combination with eco‐geographic characteristics determine their functional processes. In this study, we identified groups of vegas based on their plant composition and characterized these groups with spatial and spectral variables representing their eco‐geogra...

CAPITULO 7. YUNGAS. Las Yungas proveen múltiples recursos forestales madereros y no madereros de importancia regional, tienen una rol clave como proveedor de servicios ecosistémicos y albergan una extraordinaria biodiversidad. Con más de 3 millones de hectáreas en la actualidad, el 30% de las Yungas ha sido transformado a otros usos de la tierra y...
Article
Tree mortality and its relationships with forest structure and environmental factors have been studied for many decades using permanent plots. In the last decades, plot monitoring showed that tree mortality rates were increasing in tropical and temperate regions. We analyzed tree mortality in subtropical montane forests of Northwestern Argentina to...

Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of...

It is largely unknown how South America's Andean forests affect the global carbon cycle, and thus regulate climate change. Here, we measure aboveground carbon dynamics over the past two decades in 119 monitoring plots spanning a range of >3000 m elevation across the subtropical and tropical Andes. Our results show that Andean forests act as strong...

en Forest biomass plays an important role in the global carbon cycle. Therefore, understanding the factors that control forest biomass stocks and dynamics is a key challenge in the context of global change. We analyzed data from 60 forest plots in the subtropical Andes (22–27.5° S and 300–2300 m asl) to describe patterns and identify drivers of abo...

Aim Ecological niches shape species commonness and rarity, yet, the relative importance of different niche mechanisms within and across ecosystems remains unresolved. We tested the influence of niche breadth (range of environmental conditions where species occur) and niche position (marginality of a species’ environmental distribution relative to t...

Our knowledge about the structure and function of Andean forests at regional scales remains limited. Current initiatives to study forests over continental or global scales still have important geographical gaps, particularly in regions such as the tropical and subtropical Andes. In this study, we assessed patterns of structure and tree species dive...

Global warming is forcing many species to shift their distributions upward, causing consequent changes in the compositions of species that occur at specific locations. This prediction remains largely untested for tropical trees. Here we show, using a database of nearly 200 Andean forest plot inventories spread across more than 33.5° latitude (from...

Phenology is a key ecosystem process that reflects climate–vegetation functioning, and is an indicator of global environmental changes. Recently, it has been suggested that land-use change and timber extraction promote differences in forest phenology. We use remote-sensing data to describe regional leaf phenological patterns in combination with fie...

Environmental heterogeneity and dispersal limitation influence tree species distribution, but their relative contributions change with the spatial scale of analysis. We analyzed tree species turnover using twenty 1-ha permanent plots to quantify variation in floristic similarity explained by environmental factors and geographical distance at region...

Altitudinal gradients are associated with climatic gradients that promote species diversity. This study describes the composition, diversity and structure of trees along an altitudinal gradient in subtropical mountain forests (Yungas) in Serranias de Zapla, Jujuy province, Argentina. Three 1-ha plots at 1150 m, 1600 m and 2050 m above sea level wer...

General patterns of forest dynamics and productivity in the Andes Mountains are poorly characterized.

Forests are major components of the global carbon cycle, providing substantial feedback to atmospheric greenhouse gas concentrations. Our ability to understand and predict changes in the forest carbon cycle-particularly net primary productivity and carbon storage-increasingly relies on models that represent biological processes across several scale...

Within the tropics, a marked gradient in rainfall between dry and wet forests correlates with a well documented turnover of plant species. While water availability along these gradients is an important determinant of species distributions, other abiotic and biotic factors correlate with rainfall and may also contribute to limit species distribution...

Different components of functional biodiversity, such as functional type richness and composition, have been reported to affect the decomposition of litter mixtures. In spite of the numerous reports of these effects, mechanisms underlying patterns of decomposition in litter mixtures are still unclear. We analyzed whether mixture decomposition was a...
