Scientists in the field have collected voucher specimens since the 19th century. Today, most sit in research institutions around the world “dried, mounted, pickled, preserved, frozen and stuffed,” according to the creators of Lifemapper, an online species-distribution tool created at the University of Kansas.

Most specimens in natural history museums come with a label describing, among other things, where in the world it was collected. But where might these species migrate in the future in order to survive extreme weather, shifting seasons, invasive species, rising oceans and other threats linked to rapid climate change?

“Climate change is the most pressing problem of the 21st century, and Lifemapper provides tools to explore how climate change can impact individual species ranges as well as the species composition of communities,” said James Beach, assistant director for informatics with the Biodiversity Institute at KU. “Since human life and quality of life is dependent on the functions and services of ecosystems and natural communities, seeing how thousands and tens of thousands of species are being impacted by changing climate should be of interest to anyone interested in future generations' quality of life on planet Earth for future generations.”

To generate predictions, Lifemapper performs “species distribution modeling” based on records of where organisms have been spotted and collected, along with environmental layers such as elevation, precipitation and temperature. Then Lifemapper determines the preferred conditions for a species — and where those conditions are most likely to be found in the future under various climate settings.  

“Lifemapper has an agreement with the Global Biodiversity Information Facility to use the species data they aggregate from natural history museums and collections worldwide,” said Aimee Stewart, who serves as lead software engineer on the project. “Lifemapper uses elevation and current climate data calculated from observation stations by the Worldclim project for modeling GBIF species data. For projected future climate scenarios, we use climate data predicted for the International Panel on Climate Change Assessment Reports.”

Other KU Biodiversity Institute personnel working on Lifemapper include software engineers CJ Grady and Jeff Cavner.

In development since the early 2000s, Lifemapper today can help individual researchers anywhere in the world who lack the computing power needed to estimate the future distribution of plants and animals.

“The time and computational resources needed to perform calculations on hundreds or thousands of species can be prohibitive for an individual researcher on even a powerful desktop computer,” Stewart said. “Researchers can submit their own species and environmental data with the Lifemapper plugin to the GIS package QGIS for single or multi-species analyses with online Lifemapper tools. Lifemapper distributes these requests to one or more high performance computing environments running Lifemapper software, including the Advanced Computing Facility here at KU, where a divide-and-conquer approach allows computations to complete far more quickly than is possible on a single machine.”

Moreover, high school students are using Lifemapper’s website to analyze changes in habitat under various climate-change conditions.

“More advanced students might use the simplest species prediction tools available through the website or download data for further geospatial analysis,” said Stewart. “The ChangeThinking project, a collaboration with the University of Michigan School of Education and their Animal Diversity Web Project, created curricula and an online workbook using Lifemapper web services to teach middle and high school students about the effects of climate change. In 2014, ChangeThinking curricula were used in 130 schools in Michigan, Kansas and other states.”

Most of Lifemapper’s funding has been collaborative, as the project partners with experts in the fields of biology, macroecology, cyberinfrastructure, computer science and education. Additionally, the National Science Foundation and NASA have provided most of the support for Lifemapper.

“As part of a partnership with UTEP’s Cyber-ShARE Center of Excellence, we have been encouraged to seek support to connect and integrate Lifemapper’s models and computational services to other earth-science modeling systems with metadata and computer semantics,” Stewart said.

The KU researchers also collaborate with the Pacific Rim Applications and Grid Management Assembly, an international collaborative framework of Pacific Rim institutions working on bringing together science applications and cutting edge computer science research.

“As part of PRAGMA, we are working with UCSD’s San Diego Supercomputer Center and UF’s Advanced Computing and Information Systems Laboratory to further modularize our systems and speed our data computation, storage and retrieval systems,” Stewart said.

With an NSF award recently recommended for funding, the Lifemapper team hopes to further refine its ability to predict shifting habitats to supply scientists and conservationists with the best data to protect species around the world.

“Tools created as part of the new grant will allow further analyses of landscapes, identifying habitat fragmentation and how it can change over time with climate change, providing managers with the ability to pinpoint areas most at risk,” Stewart said.

The term “biodiversity informatics” may not set the average person’s heart aflutter. Yet, this emerging field is revolutionizing conservation efforts, public health and agriculture in parts of the world. Now, a researcher at the University of Kansas is ready to bring comprehensive training in biodiversity informatics to students and scientists across Africa.

“Biodiversity informatics is about how to develop, integrate and use information about life on Earth,” said Town Peterson, University Distinguished Professor of Ecology and Evolutionary Biology and curator in the Biodiversity Institute. “We have a lot of raw data about biodiversity, which is to say we know places where particular species have been seen. But turning those raw data into usable information is a much bigger challenge.”

In Africa, as in much of the world, there is scant availability of training in this important discipline. This is about to change. With funding from the JRS Biodiversity Foundation, Peterson will lead multiple training sessions in four African nations: Ghana, South Africa, Kenya and Egypt.

“The people doing the training will come from around the world, and the trainees will be a range of people, from people in decision-making situations, such as a ministry of natural resources, to professors, graduate students and undergrads,” said Peterson. “We’re going to focus on people with the promise to take this training and put it to good use.”

What’s more, Peterson and his team will make videos of the training sessions, along with other learning materials, available on the Internet for anyone to access. He calls it a free online “biodiversity informatics university.”

“You have a field that’s relatively new,” said the KU researcher. “Being able to analyze biodiversity patterns worldwide is not something that’s been feasible in terms of data availability for very long. This field emerged just in the last 10 to 20 years. It requires a fair amount of technology and access to the Internet. So not just Africa, but people all over the world, including in the U.S., are looking for means of obtaining quality training in terms of how you learn these techniques. The in-person training will be in Africa, but the training materials will then be made available worldwide.”

The training could significantly enhance efforts in Africa and elsewhere in several important fields.

“Say a country has the will to protect its natural resources in biodiversity, but may not have good information about where protection should be focused,” said Peterson. “If you want to have maximum effect, you need to know where each species is. Think of the national parks in the U.S.: here you have the Rockies, the Appalachians, the Great Plains and California. But if you were starting from zero and setting up a national park system, where would you protect first? Take that question to any number of countries in Africa, and there are data out there, but they are raw. So you need to organize the data and have a framework for analyzing and interpreting the results.”

Peterson also said that public health officials could use biodiversity informatics to track transmission of infectious diseases such as malaria and dengue, while agricultural experts could know better what insects and weeds could pose a threat to crops.

This work is funded by a three-year grant from the JRS Biodiversity Foundation.

The National Aeronautic and Space Administration has announced a grant of more than $1 million to fund a collaboration that will bring together NASA remote sensing technology with predictive modeling applications to develop and maintain data about the effects of climate change.

The project is entitled "Earth, Life and Semantic Web (ELSeWeb): An Earth observation-driven, semantic web system for computational modeling of the impact of changing climate on ecosystems and human/environmental health systems." Partners in the grant include the University of Texas at El Paso, the University of New Mexico, and the University of Kansas.

At KU, the work will be led by James Beach and Aimee Stewart, who heads up KU's Lifemapper program (lifemapper.org).

The research team will seek to develop information systems that allow researchers to demonstrate potential changes in climate and ecosystem conditions. The project will link three existing information technologies, including Lifemapper, to model and analyze the ways that changes in climate will affect the distribution of animals and plants.

The Specify Software Project is enthused to announce a software co-development collaboration with the Swedish Museum of Natural History (NRM) to create extensions to Specify for the web. NRM scientists and software developers will share the design vision and engineering tasks with Project staff in the Biodiversity Institute to produce a Specify web client (program) for browser-based access to remote Specify databases. The web client will complement the three desktop software versions of Specify currently available for Windows, Mac OSX, and Linux computers. The web client will enable new kinds of collaborations among collections institutions--a single Specify installation will now be accessible over the internet for querying, data entry and other analytical functions with data from multiple collections and institutions. The effort will also produce a web portal for Specify which will be a more traditional web site for open access to specimen data held in Specify databases. The Specify web client and web portal will be available and supported as open source extensions to Specify in 2012.
