Molecular Ecology at MLML
By Dr. jonathan CeDer
The lnvcrtebrare Zoology laboratory ar
the Moss Lmding Marine Laboratories is
led by Dr. Jonathan Geller, who took over
this posicion when Dr: James Nybakken
recin..'Cl in the faU of 1998. Dr. Geller teaches
Invertebmte Zoology and Macine Ecology,
but also has a new aJUI5e in marine molecular biology and biotechnology. The research
hy Dr. Geller and graduate srudems in the
Invertebrate Zoology lab also hrtS a molecular
flavor. The general theme is d1e application
of molecular tools ro questions abour marine
invertebrates and their interactions with each
other arrd their environment-what is now
often referred co as "molecular t>cology."
Research topics io the lnvertehi"Jte Zoology
laborarory are diverse, bttt em bt broadly
cttegorized as involving ma1ine conservation biology, and genomic approaches ro
invertebrate evolutionary biology. In the
area of marine conservation biology, Dr.
Geller and his srudcnrs have primarily
focused on the issue of biological invasions. Past pro jeers have used molecular
techniques co derecr invasions, track their
sources, and srudy the population genetic
consequences of the invasion process. ,
For example, mussels in the genus .Mytilus
are f.uniliar in Cal.ilOmkts bays, bur genetic
rechniques have Wl<XJVI:red. the presence ofa
European invader mingled with our native
species. "These mussels cannot be distinguised
reliably by shape, size, or color: Molecular
markcrs uncovered the distribution of the
invader (mostly in southem Cal.ilOmia) and
shoWed that the exotic and narive mussels
arc hybridizing, pre;eming a threat co the
pristine, narive gene pool. Because DNA is
preserved in museum specimens, Dr. Geller
was able co show that southern C'llifomian
mi..ISSCI populations in the 1850's wae native,
implying that the European specie; aaived
later and perhaps displaced the native ~pecies.
Another project rargeted cl1e inrroducetl
northern European Green crab, Ctm:nius
nutenas. Molecular markers rcvealec.l rhar
a sibling species with a Mediterranean
origin exists, and lm invac.led South Africa
and Japan along wirh che northern species. Molecular analysis of the C.alifornia
invasion by green crabs shows tbar these
crabs did not come c.lireccly co California
from Europe but instead came from New
England, which was invaded abour !00
years prior. A similarly delayed leap-frog
invasion ofTasmania from Australia \vas
detected. These cases suggest that m:u1y
invasions spread not by natural dispersal,
but by human acriviries.
Also in the area of conservation biology, the
Invertebrate Zoology laboratory ha~ invt'Stigated genetic scructure.in populations ofan
exploited sea cururnber, IsostichopLtS fitscJts,
in the Galapagos Islands. MLML graduate
Heather I.ohr an..Uy.t..ed nutochond.ri..U DNA
variation in populacioru fiom me Galapagos
lsland, mainland .Ecuador, and the Gulf of
California to show a high rare of gene Bow
between concin..:mal South America and the
islands. but litde g~ecic exchange with central America. Although these data do suggest
char sea cuctunber larvae fiom rhe mainland
may recruit to the Galap-,tgos, it remains
uncertain whether currenr level.~ ofexploitation can be stL~ined.
In the are-a of evolutionary biology, rhc
focus has been on the evolution of sym·
biosis, clonaliry, and allotecognilion in sea
anemones. Many se-a anemones (as well as
corals and other invertebrates) host phorosynthetic microorganisms (called zooxanthellae) in a symbiotic relationship: the sea
anemone gets a energetic boost, and the
zooxam hellae get a home. However, not
all sea anemones or corals host zooxanthellae, which suggest either they lack the
ability to form such partnerships--or that
the partncrshjp is not always beneficial.
By studying rhe evolutionary relationships
in one group of sea anemones, Dr. Geller
has shown r:har symbiotic parmerships
form and dissolve over evolutionary rime.
Thus, it appears that nonsymbiotic species
have the poremial ro host zooxanthdlae bur simply do nor. This observation
provokes questions about the cellular and
molecular mechanisms involved in symbiosis, as well as the ecological situations
in which partnerships are favorable.
The Invertebrate Zoology lab has adopted
functional genomic merhods-the analysis of
gene expression----to in~ the genes dult
regulate symbiosis. Sea anemones, like many
invertebrate animals, ctn reprodu~ ac;exually
by splitting their bodies in rwo or pieces and
.ocgrowing lost parts. Similar ro symbiosis, this
type of clonal reproduction comes and goes
over evolutionary rime, and the Invertebrate
Zoology lab is using genomic methods ro
isolare the genes that control fission in sea
anemones to rry to understand how fission
"re-evolves" over and ~n.
bstly, Dr. Geller has received an award
from the National Science Foundation to
invesdgate genes thar control allorecognrion-the ability of organisms to recognize
the distinction berween chei r own tissues
and tho~e of another individual.
Allorecognirion is Familiar to us in rerm~ of
organ transplants. An organ transplam will
typically be rejected unless tbe donor is a
immunological "march." For htunans, our
immune system mediates allorecognition.
Allorecognition is an ancient phenomenon,
however, and sea anemones recognize other
sea anemones by touch and display aggressive behaviors coward them. Clonemates,
produced by fission, :u·e nwer attacked.
Dr. Geller is working to isolate and
done the receptor molecules that conrrol allorecognition in St>a :u1emones and
investigate their relationship, if any, ro the
inunuoe systems of other organisms.
