STRI showcased in Panamanian museumsThe new facilities of MuseoAntropológico Reina Torres deArauz (MARTA), located inLlanos de Curundú, PanamaCity, was dedicated by first ladyVivian de Torrijos on Monday,August 21. For its inauguration,México's Soumaya Museumloaned 32 sculptures of AugusteRodin, until November. Visitsto the museum are free ofcharge to all until October 15.
The Salón de Oro [GoldRoom]exhibit includeshistorical photographs (seeMarcela Camargo, Ira Rubinoff,Reina Torres de Araúz, AdelaGómez and others in the photobelow), gold pieces and artifactsfrom Panama's Barriles site,Gran Darién, El Gran Cocléand a sample of gold andceramic pieces and otherartifacts found at Cerro JuanDíaz by STRI archaeologistRichard G. Cooke and his team(see photo above). Cookecontributed in the productionof the text with archaeologistTomás Mendizábal (photo inpage two), director of MARTA,who holds a Ph.D. from theUniversity of London.
Digitalization of the collections,an archaeology laboratory, aspecialized library, a researchcenter to study Panama's history and pre-history and artclasses are among theup-coming phases of museumdevelopment.
The roofed area of 2,500m2houses spacious showcases, anauditorium, an amphitheater,plus 3,500m2 for outdoorsactivities, access for thehandicapped, adjacent to sixhectares of dry tropical forest.The museum also plans toconduct sample archaeologicalexcavations and offer guidedtours into the forest in the nearfuture.
Local designers also invited theSTRI community to visit thePanamá Gráfico 06 at Museo deArte Contemporáneo,a few blocks fromSTRI headquarers.
The exhibit showcasesSTRI's BiennialReport 2002-2003,designed by Orosmánde la Guardia.

Trematode parasites in tropicalmangrove habitatsParasites are an
invisible but pervasive
part of many
communities. Often
undetected by the
casual observer,
parasites can play a
critical role in the
ecology of free-living
organisms- driving
population dynamics
and structuring
communities.
Mangroves and rocky
shores in the Bay of
Panama often support
high densities of cerith
snails (Cerithium
stercusmuscarum)
which serve as first
intermediate hosts to
several species of
parasitic trematodes.
These utilize several
different hosts
throughout their life
cycle. The larval stages
of the parasites
asexually reproduce in
snails, castrating their
molluscan hosts.
Free-swimming larvae
are released from
castrated snails and
infect either molluscs,
crustaceans or fishes
where they encyst and
await being eaten by a
final vertebrate host.
Here, Aileen Terrero
and Emily Thompson,
interns working in with
STRI marine biologist
Mark Torchin, collect
shore crabs
(Pachygrapsus
transverses) at Punta
Culebra to examine the
potentially fatal role
these parasites play in
the behavior of the
crabs.
Crabs that are heavily
infected by cysts of
one trematode species,
appear to die more
frequently than
uninfected crabs,
perhaps due to
increased predation by
their final bird hosts. In
addition to examining
how these parasites
might modify the
crab's behavior making
them more susceptible
to predation, their
research examines
what factors make
snails prone to
infection, how
parasites chose their
hosts and, the extent
to which parasitic
castration reduces the
abundance of snail
hosts in nature.

Los parásitos son una

muchos casos pasan
inadvertidos para el
observador casual, y
pueden jugar un papel
crítico en la ecología
de organismos libres,
al conducir la dinámica
de poblaciones y
estructurar

Con frecuencia Las
orillas rocosas y los
manglares de la Bahía
de Panamá mantienen
con frecuencia altas
densidades de
caracoles Cerithium
stercusmuscarum que
hacen de primer
hospedero
intermediario de varias
especies de
tremátodos
parasíticos. Los
tremátodos utilizan
hospederos diferentes
a través de su ciclo de
vida. Los estadíos
larvales de estos
parásitos se
reproducen
asexualmente en
caracoles, y castran a
sus hospederos
moluscos. Las larvas
que nadan libres salen
de los caracoles
castrados e infectan a
otros moluscos,
crustáceos o peces, se
enquistan y esperan a
que se los coma un
hospedero vertebrado.
Aquí, Aileen Terrero y
Emily Thompson,
pasantes que trabajan
con el biólogo marino
de STRI, Mark Torchin,
colectan cangrejos de
la orilla (Pachygrapsus
transverses) en Punta
Culebra, para examinar
el papel
potencialmente fatal
que estos parásitos
juegan en la conducta
de los cangrejos.
Los cangrejos que se
infectan intensamente
con quistes de una
especie de tremátodo,
parecen morir con más
frecuencia que los no
infectados, quizás
debido a un aumento
en la depradación por
parde de sus
hospederos finales, las
aves. Además de
examinar cómo estos
parásitos pueden
modificar la conducta
de los cangrejos
haciéndolos más
susceptibles a la
depredación, los
estudios del equipo de
Torchin examinan qué
factores hacen a los
caracoles más
propensos a la
infección, cómo los
parásitos escogen sus
hospederos y, hasta
dónde la castración
parasítica reduce la
abundancia de
caracoles hospederos
en la naturaleza.
