Our knowledge about the structure and function of Andean forests at regional scales remains limited. Current initiatives to study over continental or global still have important geographical gaps, particularly in regions such as tropical subtropical Andes. In this study, we assessed patterns tree species diversity along ~ 4000 km latitude m elevation range forests. We used Forest Network (Red de Bosques Andinos, https://redbosques.condesan.org/) database which, present, includes 491 forest...
It is largely unknown how South America's Andean forests affect the global carbon cycle, and thus regulate climate change. Here, we measure aboveground dynamics over past two decades in 119 monitoring plots spanning a range of >3000 m elevation across subtropical tropical Andes. Our results show that act as strong sinks for (0.67 ± 0.08 Mg C ha-1 y-1) have high potential to serve future refuges. Aboveground are driven by abiotic biotic factors, such size-dependent mortality trees. The...
General patterns of forest dynamics and productivity in the Andes Mountains are poorly characterized. Here we present first large-scale study Andean using a set 63 permanent plots assembled over past two decades. In North-Central tree turnover (mortality recruitment) growth declined with increasing elevation decreasing temperature. addition, basal area increased Lower Montane Moist Forests but did not change Higher Humid Forests. However, at higher elevations lack net excess mortality...
The long-term survival of Andean forest landscapes (AFL) and their capacity to contribute sustainable development in a context global change requires integrated adaptation mitigation responses informed by thorough understanding the dynamic complex interactions between ecological social components. This article proposes research agenda that can help guide AFL efforts for next 15 years. was developed July 2015 June 2016 through series workshops Ecuador, Peru, Switzerland involved 48...
Plastic production has been increasing exponentially in the last 60 years, but plastic disposal is out of control, resulting pollution all ecosystems on Earth. Finding alternative environmentally sustainable choices, such as biodegradation by insects and their associated gut microbiota, crucial, however we have only begun to characterize these ecosystems. Some bacteria one fungus previously identified Greater Wax Moth larvae (Galleria mellonella L., Lepidoptera, Pyralidae) located mainly...
Abstract As global climate change leads to warmer and dryer conditions in the central Andes, alpine plant communities are forced upward displacements following their climatic niche. Species range shifts predicted have major impacts on by reshuffling species composition abundances. Using a standardized protocol, we surveyed permanent plots four high Andean summits NW Argentina, which from 4,040 4,740 m a.s.l. After baseline survey 2006–2008, resurvey same 2012, again 2017. We found...
The sustainable management of municipal solid waste (MSW) presents a pressing global challenge. This study introduces an innovative methodology for analysing open dumps in Tucumán, Argentina, using unmanned aerial vehicles (UAVs) and DroneDeploy software data collection, coupled with QGIS estimating contamination risk at the sub-basin level. By integrating satellite imagery, ground surveys, high-resolution UAV imagery multi-criteria decision analysis within geographic information system, we...
Abstract Wood density is a critical control on tree biomass, so poor understanding of its spatial variation can lead to large and systematic errors in forest biomass estimates carbon maps. The need understand how why wood varies especially tropical America where forests have exceptional species diversity turnover composition. As identity composition are challenging estimate remotely, ground surveys essential know the trees, whether measured directly or inferred from their identity. Here, we...
La biomasa aérea de los bosques se estima habitualmente mediante ecuaciones alométricas aplicadas a datos parcelas forestales. Sin embargo, cuando no existen mediciones locales directas la (valor referencia), resulta difícil cuantificar el sesgo (porcentaje sobre o subestimación). Para estos casos, proponemos comparar estimaciones obtenidas con diferentes y analizar sus relaciones patrones estructura del bosque en gradiente ambiental estudiado. En las selvas subtropicales montaña (i.e.,...
1 To investigate life-history differentiation and an objective functional classification of tree species we analysed the demography 29 in subtropical montane forests north-western Argentina. 2 We computed 13 growth, demographic, abundance distribution variables based on: (i) two 5-year re-measurements stems ≥ 10 cm diameter at breast height (d.b.h.) 8 ha old growth forest 4 secondary forest; (ii) assessments crown illumination; (iii) sapling counts under shade on landslides. 3 assessed...
Questions: What are the effects of soil, topography, treefall gaps, tree species composition, and density on liana composition total abundance? Location: A 6-ha permanent plot in a subtropical montane forest northwest Argentina. Methods: Multiple regressions were used to quantify associations abundance with edaphic, disturbance community variables. Gradients quantified using principal components analysis (PCA). Results: Liana was correlated most strongly soil phosphorus concentration...
In a subtropical montane forest of north-western Argentina (27°S, 1000 m elevation), we analysed the effect crown illumination, trunk diameter, foliar phenology and tree species identity as determinants liana–host associations, well spatial pattern liana abundance in 6-ha permanent plot. We recorded 2346 individuals ≥ 2 cm 2320 trees 10 dbh. Sixty-five per cent hosted at least one stem. Large well-lit were more likely to support lianas supported than small shaded trees. Yet, when...
Abstract Aims Ligustrum lucidum , native to China, is one of the dominant exotic and invasive tree species in secondary forests Argentina. (1) We assessed its invasion during 20 yr post‐agricultural dominated by species, (2) evaluated demographic rates individuals under away from L. trees that invaded these forests. Locations Four 1‐ha permanent plots forests, subtropical Andes Tucumán, Methods quantified (≥10‐cm diameter) 1991 2011 within four analysed annual growth mortality trees. For...
