Educational Background

• B.S. Biology - Antioch College

• M.F.S. - Yale School of Forestry and Environmental Studies

• Ph.D. Entomology – Penn. State University

Dipetalogaster maximus – from a subfamily known as “kissing bugs”.

Blood-sucking insects from southern U.S. and Latin America.

Chagas diseaseActually a Protist –Trypanosoma sp.

• A protist• Irreversible damage to the heart or intestinal

tract that appears 10 to 20 years after infection.

• Treatable in early stages, but not in later stages. Lethal.

Chagas disease is spread from feces of the vector.

Kissing Bugs live in roof and walls of huts.

Giardia lambliagiardiasis – travellers diarrhea

• The parasite (a Protist) attaches itself to the lining of the small intestines in humans, where it sabotages the body's absorption of fats and carbohydrates from digested foods.

• Result from ingestion of water or food contaminated with human sewage.

• Also attributed to animals – beaver. Hence ‘beaver fever.’

How many known species are there in the world?

Are there any new species left to discover?

Microcebus lehilahytsara – Discovered August 2005.Named for U.S. lemur expert Steve Goodman ("lehilahytsara" is Malagasy for "good man"). •The new primate species brings

the total number of known lemur species to 49—all of which occur naturally only on Madagascar or the nearby Comoros islands.

•Lemurs are the closest living analogs to our ancient primate ancestors who lived about 55 million years ago

•One-third of lemure species are extinct.

•Remaining species are under threat from hunting and habitat destruction.

• Trevor Jones,1* Carolyn L. Ehardt,2 Thomas M. Butynski,3 Tim R. B. Davenport,4 Noah E. Mpunga,4 Sophy J. Machaga,4 Daniela W. De Luca4 A distinct species of mangabey was independently found at two sites 370 kilometers apart in southern Tanzania (Mount Rungwe and Livingstone in the Southern Highlands and Ndundulu in the Udzungwa Mountains). This new species is described here and given the name "highland mangabey" Lophocebus kipunji sp. nov. We place this monkey in Lophocebus, because it possesses noncontrasting black eyelids and is arboreal. L. kipunji is distinguished from other mangabeys by the color of its pelage; long, upright crest; off-white tail and ventrum; and loud call. This find has implications for primate evolution, African biogeography, and forest conservation.

Discovered in 2002,

in Namibia

New Species are constantly being discovered

Now the bad news.

Not that humans had anything to do with it.
