The Andean dry montane woodland ecosystem is among the most important locations because that the conservation of tropic diversity in the world. Over millennia, temperatures have actually caused plant populaces to migrate along the east Andean slope in order to uncover their climatic niche. ABERG is concentrated on the past, current, and also future distributions of tree diversity in this ecosystem.

Past Distribution and also Diversity

Andean lakes have the right to serve together mirrors right into the past. End time, pollen from adjacent vegetation is buried within lake sediments which, as soon as extracted, deserve to be systematically analyzed to rebuild ecosystem dynamics for the surrounding area. Mark Bush and Dunia Urrego have been completely investigating previous vegetation in the Andes and also have collaborated with other ABERG members come produce many important and informative papers:

Current species Distribution on one Elevational Gradient

In 2003, Norma Salinas, Miles Silman, Jason Bradford (then of the Missouri factory Garden), wilhelm Farfan, and also Karina Garcia established the an initial nine 1 ha plots throughout the Trocha Union within Manu Park and within what is now the Wayqechas Cloud forest Reserve. In successive field campaigns, the total number of 1 ha plots was enhanced to 22. This plots range in elevation from 750 to 3625 meter in elevation. Monitoring projects have determined each separation, personal, instance tree stem and also tracked the growth due to the fact that the production of the plots. This information has proven an important to understand each species distribution patterns in the context of elevational, climatalogic, biogeochemical, and biotic constraints.

Several other plots have been established by members of ABERG. Ken Feeley has developed several smaller sized plots top top the treeline border to understand how combinations of floor use and also climate change may influence tropical species migration. Imma Oliveras has likewise established a network that plots to study trends in fire frequency on the migration and also carbon dynamics the Andean forests.

Combined, these irreversible research plots have provided an essential insights into distribution modeling, carbon sequestration, varieties interactions, and data native them have actually been incorporated into vertebrate and also invertebrate studies.

Future distributions from Modeling

Data native the ABERG tree plots combined with collected neotropical types data from GBIF has enabled for research into distribution projections given local and worldwide climate change. Mile Silman and also Ken Feeley have generated plenty of publications on intended distributions and the possibilities for extinction for tropical montane tree species. These papers suggest expected extinctions because that montane cloud forest types with climate change and imperfect upslope migration.
