Biodiversity creates biodiversity.
That point comes through loud and clear when you read the scientific paper on the apple maggot/parasitic wasp research led by UC Davis evolutionary ecologist Andrew Forbes.
The news embargo lifted at 11 a.m. today and the research will be published Friday, Feb. 6 in the journal Science.
When the apple maggot shifted hosts from the hawthorn to the apple, that triggered a cascading effect on the ecosystem.
A parasitic wasp (Diachasma alloeum) that attacks the apple maggot (Rhagoletis pomonella) has “formed new incipient species as a result of specializing on diversifying fly hosts, including the recently derived apple-infesting race of R. pomonella,” Forbes said.

A host race is a group of organisms in the process of becoming a new species due to its close association with a particular host (plant or animal).
In this new study, Forbes and his co-authors showed that the wasp D. alloeum is undergoing the same evolutionary changes.
“The research shows the process of speciation in action and might tell us more about why certain groups of organisms are more diverse than others.” said Forbes, who received his doctorate from the University of Notre Dame and is now a postdoctoral researcher in professor
The research, titled “Sequential Sympatric Speciation Across Trophic Levels,” provides insight into what Forbes calls “the tangled bank of life.”
“As new species form, they create new opportunities for others to exploit which, in turn, begets ever more new species,” he said.
“And all this is happening right before our eyes in our own backyards.”

It’s official. University of California, Davis scientists who manage campus biological collections have just received a five-year, $4 million grant to research the biodiversity of fungi, bacteria, plants, insects and vertebrates on the Indonesian island of Sulawesi, a southeast Asian island threatened by the loss of biodiversity in its tropical forests.
The International Cooperative Biodiversity Group Program is funding the grant. This is a multi-agency program led by the National Institutes of Health with contributions from the U.S. Department of Agriculture, Department of Energy, and the National Science Foundation.
Principal investigator Daniel Potter, a plant systematist at the Agricultural Experiment Station and director of the UC Davis Herbarium, said “the alarming rate at which biodiversity is being lost in many tropical regions has resulted in an urgent need for such efforts.”
The grant, “Biodiversity Surveys in
The international team involved in the grant includes UC Davis, UC San Francisco, UC Berkeley and three
Biodiversity refers to all living things in a region and to their interactions of with each other and their surroundings.
The results are expected to aid human health, energy needs, and biodiversity conservation.
The project is sorely needed, said entomologist Lynn Kimsey, director of the Bohart Museum of Entomology and chair of the Department of Entomology. “For biologists,
The Bohart houses some seven million specimens from throughout the world and is the seventh largest insect museum in
Potter described it as an extraordinary opportunity. "When the call for the International Cooperative Biodiversity Group grant proposals came out in the fall of 2007, several of us involved in management of the biological collections here at UC Davis thought this could be an extraordinary opportunity to initiate a project that would include study of organisms in the multiple taxonomic groups (fungi, bacteria, plants, insects, vertebrates) covered by our collections and to engage in international collaborative research with implications for human health, energy needs, and biodiversity conservation.”
Potter said that two other key participants in the project are his former student, Jeanine Pfeiffer, research director for social sciences at the Earthwatch Institute, and Elizabeth Widjaja, research botanist at Herbarium Bogoriense,
“Thanks to the excellent hard work of many colleagues at UC Davis, UC Berkeley, UC San Francisco, and three Indonesian institutions, and with the wonderful guidance and assistance of the outstanding Interdisciplinary Research Support group in the Office of Research here at UC Davis, we were able to put together a strong proposal for an ambitious and exciting project," Potter said.
UC Davis is the lead institution from the
The project is organized into six associate programs: macro-organism surveys, led by Widjaja, microbial surveys, led by discovery of energy solutions, led by discovery of human health solutions, led by Len Bjeldanes, professor of toxicology, UC Berkeley; conservation research and vertebrate surveys, led by and conservation partnerships, training and ethics, led by Pfeiffer.
“We will also be forming partnerships with private companies aimed at the commercial development of natural products for pharmaceuticals and energy production,” Potter said. They have also lined up collaborators from several other leading research institutions, including the
Potter said the results of the project will make significant contributions to a broad range of issues, including
- knowledge of the patterns of biodiversity in southeast Asia
- identification and isolation of natural products with potential therapeutic value to treat globally important diseases and to address human energy neeeds
