The Andean tropical montane woodland ecosystem is one of the most necessary locations for the conservation of tropical diversity in the people. Over centuries, temperatures have resulted in plant populations to migrate along the eastern Andean slope in order to find their climatic niche. ABERG is concentrated on the past, existing, and future distributions of plant diversity in this ecosystem.

Past Distribution and also Diversity
Andean lakes deserve to serve as mirrors into the past. Gradually, pollen from adjacent vegetation is buried within lake sediments which, as soon as extracted, can be systematically analyzed to rebuild ecodevice dynamics for the neighboring location. Mark Bush and also Dunia Urrego have been thoapproximately investigating past vegetation in the Andes and have collaborated through other ABERG members to create many kind of crucial and also informative papers:
Current Species Distribution on an Elevational Gradient
In 2003, Norma Salinas, Miles Silman, Jakid Bradford (then of the Missouri Botanical Garden), William Farfan, and also Karina Garcia establiburned the first nine 1 ha plots throughout the Trocha Union within Manu Park and within what is currently the Wayqechas actually Cloud Foremainder Reserve. In succeeding field campaigns, the total variety of 1 ha plots was boosted to 22. These plots array in elevation from 750 to 3625 meters in elevation. Monitoring campaigns have actually determined each individual tree stem and also tracked its growth since the development of the plots. This indevelopment has prstove important to understand each species distribution fads in the conmessage of elevational, climatalogic, biogeochemical, and also biotic constraints.
Several various other plots have actually been establiburned by members of ABERG. Ken Feeley has established a number of smaller plots on the treeline boundary to understand also how combicountries of land also usage and climate readjust may impact tropical species migration. Imma Olivages has actually additionally establimelted a network of plots to research patterns in fire frequency on the migration and also carbon dynamics of Andean woodlands.
Combined, these permanent research study plots have gave instrumental insights into distribution modeling, carbon sequestration, species interactions, and data from them have actually been included right into vertebrate and also invertebrate researches.

Future Distributions from Modeling
Documents from the ABERG tree plots merged through accumulated neotropical species information from GBIF has actually allowed for research study into distribution projections provided neighborhood and also worldwide climate readjust. Miles Silman and also Ken Feeley have produced numerous publications on intended distributions and the possibilities for extinction for tropical montane tree species. These records suggest intended extinctions for montane cloud forest species via climate adjust and also imperfect upslope migration.
