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
Vascular epiphytes are an important component of the flora of subtropical regions, but they remain understudied compared to tropical regions. Subtropical montane region of Yungas in Argentina has high epiphyte diversity, but information on epiphytes remain in little disseminated sources such as herbariums, theses and publications not available on t...

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...
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...

El arbolado urbano brinda múltiples beneficios a la población, tales como como la provisión de sombra y la regulación del clima. También puede contribuir a la conservación de plantas nativas de la ecorregión en la que se encuentra la ciudad, aunque existe poca información al respecto. En este trabajo se analizaron la riqueza, la cobertura y la comp...

Ligustrum lucidum is a highly invasive East Asian tree that successfully colonizes several subtropical and temperate areas around the world. Its invasion capacity results from a widespread human use mostly in urban and periurban settings, very abundant fruit and seed production, small bird-dispersed fruits, high germination rates, resprouting capac...

RESUMEN. Gleditsia triacanthos es una especie exótica invasora, ampliamente distribuida en varias ecorregiones de la Argentina. Cuando invade, esta especie forma bosques monoespecíficos de estructura y dinámica poco conocida. Investigar estos aspectos es fundamental para evaluar el comportamiento de la invasora y la capacidad de las especies nativa...
Article
Vascular epiphytes were traditionally studied in pristine forests, and few studies were performed to understand their colonization in secondary forests, particularly in subtropical areas. Many secondary forests are invaded by exotic tree species that threaten biodiversity, and the impact of invaders on epiphytes remains unknown. The structure, dive...
Article

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...
Article
Liana dynamics in secondary and mature forests are well known in tropical areas dominated by native tree species. Outside the tropics and in secondary forests invaded by exotic species, knowledge is scarce. In this study, we compare liana communities between secondary and mature forests dominated by native species in a subtropical montane area of S...
Article

Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vas...
Article
Changes in density and basal area of lianas ≥2 cm diameter were monitored in two 1-ha permanent plots in a subtropical montane mature forest of north-western Argentina. Liana stems were identified and measured at 130 cm from the main rooting point in two censuses conducted in 2003 and 2015. Between censuses, the density of liana stems decreased 13....
Article
Gleditsia triacanthos L. is a woody species native to North America that has invaded Uruguay, Spain, Australia, South Africa and several countries of Central and Eastern Europe. In Argentina, it has become one of the most important invasive woody species and has a high potential to continue spreading. In this study, we review different aspects of G...
Article
The commensalistic interaction between vascular epiphytes and host trees is a type of biotic interaction that has been recently analysed with a network approach. This approach is useful to describe the network structure with metrics such as nestedness, specialization and interaction evenness, which can be compared with other vascular epiphyte-host...

The aims of this work were to describe the conservation status of riparian forests located in a mountain subtropical basin of Tucumán province, Argentina, and assess how the quality of riparian forests is related with altitude, plant species richness, proportion of exotic species, and Total Suspended Solids (TSS) in adjacent rivers. Composition and...

Lianas are more diverse and typically more abundant in tropical than temperate forests, with subtropical forests in between. In this chapter, we revised geographical, taxonomical and ecological patterns of woody lianas in subtropical forests of Northern Argentina, including Mountain Forests (MF), Atlantic Forests (AF); and Dry and Humid Chaco Fores...

En la sierra de San Javier (Tucumán, Argentina) se presentan bosques secundarios nativos e invadidos, estos últimos dominados por Ligustrum lucidum, que afecta la biodiversidad nativa. Analizamos la influencia del bosque dominado por L. lucidum sobre las comunidades de lianas en comparación con bosques secundarios nativos sin dominancia de especies...

Native and invaded secondary forests are present in sierra de San Javier, the latter dominated by Ligustrum lucidum, which exerts an influence on native biodiversity. We analyzed the influence of the forest dominated by L. lucidum over liana communities compared to native secondary forests without dominance of exotic species. Forests were compared...

We report an investigation about plants with therapeutical uses in indigenous communities of Quilmes, northwestern Argentina. We identified 84 species with medicinal uses, 64.3% of which were native. Curation usually takes place inside the domestic units, and plants are collected in their own orchards and gardens or in the circundant scrublands. Th...
