| ABSTRACT The Tayrona National Natural Park, located on the Colombian Caribbean coast, has a coastline shaped by cliffs and bays in its western part, with the presence of coral formations. In 2005, a coral formation dominated by Acropora palmata affected by lesions similar to those caused by White Pox disease was found in Cinto bay. Subsequently, 15 lesions were followed and photographed in three different occasions (May and August 2006 and March 2007), coinciding with the two contrasting climatic seasons of the region. Permanent growth was found in all lesions with an average of 0.8 cm2/day . Contrary to what was observed with white pox and other diseases in the region, these lesions did not stop growing when the temperature dropped in the first months of... |

| Se evaluaron 20 formaciones coralinas del área de Santa Marta en términos de: 1) composición y abundancia de los componentes del sustrato y 2) prevalencia de enfermedades coralinas y blanqueamiento. Para obtener la información se utilizaron bandas de 10 x 1 m y 10 x 2 m respectivamente. Se registró un total de 33 especies de corales duros. Las algas y los corales fueron los componentes de mayor cobertura, sin embargo sus promedios variaron ampliamente en el área de estudio (coral= 4.0 ± 0.9 %-62.0 ± 7.2 %; algas = 30.6 ± 11.0 %-78.3 ± 3.0 %). Las especies de coral con coberturas promedio más altas fueron Colpophyllia natans, Diploria strigosa, Acropora palmata y Montastraea cavernosa (7.5 ± 2.7 %, 6.7 ± 2.1 %, 4.0 ± 2.8 % y 3.8 ± 1.0 %, respectivamente).... |

| Los arrecifes coralinos, uno de los más bellos e importantes ecosistemas de nuestro planeta, han existido por más de 200 millones de años, sobreviviendo a grandes cambios durante su historia (glaciaciones, extinciones masivas, entre otros). Sin embargo, durante las últimas tres décadas se han registrado grandes y súbitos cambios en el medio marino que ajuicio de algunos investigadores ponen en peligro la supervivencia de corales y arrecifes coralinos. Uno de los mayores problemas que enfrentan los arrecifes coralinos hoy en día es la aparición de enfermedades que atacan a los corales, la base de estos ecosistemas. No existe un consenso sobre si estas enfermedades son realmente nuevas o no, pero lo que sí se sabe es que algunas de ellas están creando... |

| ABSTRACT Seagrass meadows have stood out for being very effective fixing atmospheric carbon, among others, due to their ability to produce plant biomass. Therefore, the values of shoot density (m2), biomass (cores) and carbon present in 12 locations with Thalassia testudinum at the Colombian Caribbean (La Guajira and San Andrés Island) were quantified. The biological samples were processed in laboratory until obtaining the values of aerial, underground and total dry weight, and the estimation of the carbon was stablishing from a ratio of 35 % of the dry biomass. Statistical tests were carried out to determine significant differences between the sites, highlighting the aerial biomass in La Guajira and the underground biomass in San Andrés. It was calculated... |
