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 disease
Actually 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 lamblia
giardiasis – 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.

The Highland Mangabey Lophocebus kipunji: A New Species of
African Monkey
Trevor Jones,1* Carolyn L. Ehardt,2 Thomas M. Butynski,3 Tim R. B.

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

This Enypniastes, a transparent sea
cucumber, creeps forward on its many
tentacles at about 2 cm per minute while
sweeping detritus-rich sediment into its
mouth at 2,750 meters in the northern Gulf
of Mexico.

Now the bad news.
Not that humans had anything to do with it.
