  abstract = {{T}he {I}nternational {C}ensus of {M}arine {M}icrobes ({IC}o{MM}), together with the {S}outh {A}merican and {C}aribbean {S}teering {C}ommittees of the {C}ensus of {M}arine {L}ife program ({C}o{ML}), supported the initiative of launching a regional l{C}o{MM} node ({LAC}ar {IC}o{MM}). {T}his network aims at promoting discussions among scientists currently involved in marine microbial studies carried out at both the {S}outh {A}merican and the {C}aribbean regions, in order to evaluate the research capabilities and to identify complementary strengths and/or possibilities for enhanced collaboration, that would improve the knowledge on marine microbes and their biodiversity in both regions. {W}e present an overview and discussion on some of the directions of current research on marine microbes in these regions. {C}oncerning the marine phytoplankton studies, the best known taxonomic groups are diatoms and dinoflagellates. {I}n {M}exican marine waters, the number of taxa recorded to date is of about 1400. {S}tudies dealing with bacterial, phytoplankton and/or cyanobacterial dynamics are carried out in the {C}aribbean coastal and oceanic marine systems, underscoring the importance of various environmental states, modulated by geographic and seasonal patterns as well as by the expression of large {S}outh {A}merican rivers. {O}ne of the main issues of this type of survey is the determination of wet and dry seasonal patterns of bacterial dynamics, in seascapes off {P}uerto {R}ico, with moderate to absent river inputs. {P}hytoplankton and bacterioplankton dynamics are also studied in {F}. {G}uiana coastal and shelf systems under direct {A}mazon influence, well known for their important fisheries resources, as well as in other {S}outh {A}merican marine systems influenced by important fresh water inputs or under upwelling conditions. {B}acterial and/or picoeukaryotes diversity are assessed in particular marine systems such as coastal lagoons in {U}ruguay, the {R}io de la {P}lata estuary and adjacent areas, as well as in sediments of the {O}xygen {M}inimum {Z}one ({OMZ}) off {S}outh {A}merican {P}acific coast, and in anoxic waters of the {C}ariaco {B}asin. {F}indings of a diverse range of pico-autotrophs ({P}atagonian shelf) and particular communities of big filamentous bacteria ({OMZ} zone off the {S}outh {A}merican {P}acific) represent recent discoveries in those areas. {I}n polluted coastal systems, bacteria with ability to degrade pesticides and hydrocarbons are currently monitored. {I}n coastal areas of the {C}olombian {C}aribbean, 64 native marine bacterial strains were isolated from sediment samples. {T}he oil-degrading bacteria are also studied in the {O}rinoco {D}elta, submitted to intensive oil exploitation. {F}urthermore, the {M}icrobial {O}bservatory of {R}io de {J}aneiro ({M}o{R}io) established in {G}uanabara {B}ay ({B}razil), constitutes a model for the study of threatened tropical coastal systems by exploring microbial biodiversity in different coastal systems (including unpolluted sites). {T}he estimation of the activity and diversity of hydrocarbon and oil-degrading bacteria is assessed also in temperate waters and sediments of coastal systems of {A}rgentina. {S}haring knowledge and capabilities in common strategies would allow a better understanding of marine microbial diversity patterns in both regions. {R}ev. {B}iol. {T}rop. 56 ({S}uppl. 1): 183-214. {E}pub 2008 {M}ay 30.},
