MUSEUM ENLISTS VOLUNTEERS IN SEARCH FOR CREEPY CRAWLIES

LOS ANGELES (AP) —
Long before Southern California was paved over with freeways and covered
with cars and millions of people, it was teeming with snakes, slugs,
spiders, snails and uncounted other slimy, creepy, crawly creatures.
it still is, say scientists at the Los Angeles County Natural History
Museum who are intent on building a better world by enlisting thousands
of people to find and catalog those creatures.
On Thursday, the scientists will unveil the museum's Urban Nature Research Center, a facility that director Lori Bettison-Varga says will serve as headquarters for the nation's first urban biodiversity study that uses a sprawling city and its environs as a research lab.
"Everybody thinks that Los Angeles is just this big, paved-over place, but it's not. It's a hotbed of biodiversity," says Lila Higgins, head of the center's citizen-science program.
scientists recently trained about 400 volunteers and armed some with
backyard traps. Now, they will beat the bushes and other spots in their
neighborhoods in search of unusual flora and fauna. Some bugs will be
taken to the center and examined while many more will have their photos
taken and emailed to the facility's 12 staffers for a closer look.

(reptiles and amphibians in Southern California) and SLIME (snails and
slugs living in metropolitan environments).

Meanwhile, the museum
is encouraging anyone with a smartphone to snap a photo of interesting
bugs, reptiles or plants and send it along.
The environmental group Conservation International has placed Southern California on its list of 35 biodiversity
hotspots — places with a hugely diverse ecosystem that includes
numerous plants, insects, lizards and the like along with large numbers
of threatened flora and fauna.
In Southern California, for
example, museum scientists have discovered 43 species of phorid flies in
recent years that they never knew existed in the region.
nothing super-special about phorid flies, except to us of course,
because we're experts on them," Brian Brown, the museum's entomology
curator, said with a smile Wednesday as a bunch of the flies were being
meticulously examined in a ground-floor exhibit hall while a group of
schoolchildren looked on google-eyed.
"But they are indicators of
what might also be here, and it just points out how little known this
city is," Brown said. "Even though there are scientific institutions
that have been here over a hundred years, we still don't know what
species live here."
And of those that are known, it isn't clear how many of them got here.
of the most common species of fruit fly — those teeny tiny bugs with a
taste for rotten bananas and an annoying dive-bombing maneuverability —
in Southern California was recently discovered to have come from a
species native to El Salvador. Its ancestors likely arrived here the
same way as an Australian gecko discovered by the museum — hitching a
ride on a plane or ship filled with plants or food.
Brown says keeping track of such transplanted insects and reptiles helps keep the ecology in balance.
"If there are 5,000 species and a nasty invasive species gets in, it's much harder for it to get established," he said.

finished talking about flies, he ventured outside to the center's
3.5-acre garden, a stone's throw from University of Southern California
residence halls across a street divided by a busy commuter rail line.
with a butterfly net, Higgins quickly rounded up a ladybug while Brown
flipped over a small bench and uncovered an army of obscure bugs, each
of which he could name.
Such curiosity helped lead to the founding
of the center after the museum asked people in 2002 to show them any
interesting spiders they came across for a study being done by Brown and
colleagues. They quickly got 5,000 specimens.
"We thought, 'What else can we do with the public?'" the entomologist recalled.
the information collected by the Urban Nature Research Center is
largely for scientists, Bettison-Varga said it can also benefit urban
planners as they propose future projects for this dense area.
a bit of passion in his eyes, Brown said a better world for bugs and
plants makes a better place for people, explaining that decomposition of
bugs, plants and other life improves the soil, which grows the plants
that clean the air. Paving over certain habitat disturbs all that.
"Ultimately the goal is to make L.A. a better place for biodiversity and for humans," he said.
