Current Research


We actively collaborate with multiple local and international initiatives. Each of these funded multi team collaborations provides travel, field work, and research support as well as many opportunities for collaboration for postdocs, graduate students, and undergraduates as well as lab collaborators.

Lab research is currently focused on the following areas:

  • Scaling in biology and allometry
  • Forecasting the fate of biodiversity and the biosphere
  • Trait-based ecology as a foundation for a more predictive ecology and biodiversity science
  • Biodiversity informatics 
  • Macroecology of biodiversity gradients 
  • The ecology and evolution of plant functional and physiological integration
  • Long-term monitoring of populations, ecological communities, and ecosystems – Tropical and temperate forests and high alpine environments.


SPARC

Conservation International (CI) and six  international universities have announced the launch of a

team of scientists that will provide tropical countries with the information needed to avoid extinctions due to climate change.  The project, Spatial Planning for Protected Areas in Response to Climate Change (SPARC), will use a big data approach to plan for effective conservation in the coming decades by modeling the climate change response of over 100,000 species in tropical ecosystems on three continents.  SPARC will model the effect ofScreen Shot 2020-12-29 at 6.24.16 PM climate change on rare tropical plant and animal species.  This will allow governments, scientists and conservationists to identify regions and ecosystems that, if protected, preserve biodiversity and critical ecosystems.  The goal is to build networks of protected areas that reduce extinctions due to climate change, at the same time delivering clean water, tourism opportunities and numerous other benefits to people.

Further, the working group is utilizing these standardized data to the create several deliverables including geographic range maps for all plant species, an integrated trait database, and a species-level phylogeny for Embryophytes of the New World.

BIEN is a network of ecologists, botanists, and computer scientists working together to document global patterns of plant diversity, function and distribution.

Here via the BIEN you will find access to:

  • Georeferenced plant observations from herbarium, plot, and trait records;
  • Plot inventories and surveys;
  • Species geographic distribution maps;
  • Plant traits;
  • A species-level phylogeny for all plants in the New World;
  • Cross-continent, continent, and country-level species lists.

The Forest MacroSystems Network 

 A National Science Foundation funded project on the experimental effects of temperature big-21on biodiversity. The purpose of this project is to generate and test theory for how temperature impacts biodiversity through its effect on biochemical processes and metabolic rate. A combination of standardized surveys in the field and controlled experiments in the field and laboratory measure diversity of three taxa — trees, invertebrates, and microbes — and key biogeochemical processes of decomposition in six cropped-10816249174_61c063170b_o1.jpgforests distributed along a geographic gradient of increasing

temperature from cold temperate to warm tropical.  This ambitious, multi-pronged, highly integrated program of theoretical and empirical research takes advantage of the special expertise at the three collaborating institutions — University of New MexicoUniversity of Arizona, and University of Oklahoma.


Bridging Biodiversity and Conservation Science

The Prof. Enquist is a core faculty participant in the program. The BBCS will mentor postdoctoral researchers through collaborative, interdisciplinary teams to create novel synthetic research in biodiversity and conservation science and other fields of study, specifically public health, epidemiology and emerging diseases; public policy, public administration, and governance; national security; or informatics.


NERC GEM – TRAIT or better known as CHAMBASA –

 In 2013, the GEM-TRAIT project will focus on a series of forest plots along an elevational transect – from treeline in the

DSC_5844Andes down to the Amazon. This project, in collaboration with the ABERG group aims to collect primary data on tree functional diversity. Over the next five years, the GEM-TRAIT protocol will be applied across all of the GEM plots across the globe headed by Prof. Yadvinder Malhi at Oxford University, UK with collaborators B.J. Enquist, Greg Asner, Miles Silman, and Sandra Diaz.  This ambitious field campaign will result in the first global dataset linking tropical tree diversity to ecosystem function. We will also work with the world’s most cutting-edge airborne remote sensing technology to explore how functional diversity and ecosystem function scale andvary at landscape scales. The first and probably most ambitious traits campaign, in the Peruvian Andes, kicked off in April 2013 and continued until November 2013. It has been named CHAMBASA (CHallenging Attempt to Measure Biotic Attributes along the Slope of the Andes). Chambasa is slang for “a lot of work” in Spanish.


Visualizing the Future of Our Forests 

In collaboration with the Aspen Center for Environmental Studies, the Institute for the Study of Planet Earth, and iPlant, we are using informatics and high performance computing to visualize future forecasts of our forests. Our site, www.ForestForecasts.org was released April 2015. It is still being updated and improved. Here you can discover and learn how given current and projected future climate and land use changes, how will our western fo4545rests change and what will our western forests come to look like?  Why Forest Forecatsts? We wanted to come up with a set of novel visualization tools but the challenge is to overcome computational limitations and disciplinary boundaries to provide useful forecasts for land managers, the general public, and for education. More specifically, given projected rates of climate change and the natural history of species there is much uncertainty in just what western landscapes, forests, cropped-untitled3.jpgand ecosystems will look like. While we can model single-species changes, advancing more complicated models for community- and forest-level is much more complicated due to unforeseen effects of species and abiotic interactions and novel climates. Perhaps more importantly, climate change is difficult for the public to understand – especially what climate change means for your ‘backyard’. Scientists, agencies, NGOs and land managers need access to ways and tools to easily communicate results and climate change forecasts to the public.  Goals: (i) To utilize new computational techniques and collaborative networks to integrate massive amounts of data from forest surveys, species observations, and the latest climate change simulations to provide detailed geographic forecasts; (ii) to build cyberinfrastructure with a web portal front end for the visualization and exploration of climate and forest change scenario at local and regional scales.

FunCaB – The role of Functional group interactions in mediating climate change impacts on the Carbon dynamics and Biodiversity of alpine ecosystems (FunCaB) and the Plant Functional Trait Courses.

Funded via the Norwegian National Science Foundation. Led by Vigdis Vandvik at the DSC_2963University of Bergen, Norway, this project brings together and international collaborative research network.  Alpine regions contribute important ecosystem functions and services, and are at the same time particularly vulnerable to the ongoing climate change. FunCaB, aims at understanding alpine biodiversity and carbon (C) dynamics under climate change. Specifically, we will disentangle the roles of and interactions between graminoids, forbs, woody and non-vascular plants and bacteria vs. fungi communities under climate change.Objectives: (i) Experimentally assess the effects of temperature and precipitation on the composition and functional groups of alpine ecosystems; (ii) Quantify the impacts and contributions of directDSC_3174
