During the expedition INVEMAR-Macrofauna II, made in 2001 throughout the continental shelf and upper continental slope of the Colombian Caribbean coast, between 20 and 500 m depth, 22 species of hermit crabs distributed in one superfamily and four families, were collected. Within the superfamily Paguroidea, the family Paguridae was the most abundant and diverse with 13 species, six species belong to family Diogenidae; the Parapaguridae was represented by two species and one species of the genus Trizocheles of the family Pylochelidae represents the first report of this family from this coast. In addition, five undetermined species of the genera Paguristes, Enneobranchus, and Iridopagurus, were also collected. Based on the collected material, the bathymetric distributions reveal species aggregation in two depth ranges (20 - 150 m and 300 - 500 m). The upper strata species show a geographic distribution pattern, seemingly related to the influence of the Magdalena river; by contrast, the species from the deeper range do not reveal any particular distribution pattern.

Knowledge of echinoderms from Zihuatanejo and Acapulco, Guerrero is currently limited to taxonomic listings. This work attempts to characterize better the community of these organisms associated to coral reefs in this region using band transects of 50 m length by 1 m width. Two samplings were carried out in 2004, one in the rainy season and other in the dry season. Ten species, three Asteroidea, six Echinoidea and one Holothuroidea, were found. The mean values obtained for diversity in the 13 study sites (1.036 bits ind-1) are considered low when compared with the maximum possible diversity (3.322 bits ind-1), and this is likely due to the dominance of the black sea urchin Diadema mexicanum and the starfish Phataria unifascialis, with densities reported of 1.45±0.60 ind m2 and 0.12±0.02 ind m2, respectively. The highest diversity was associated with low tide, which is not different between localities. The spatial arrangement of the echinoderm species composition obtained by the multidimensional scaling analysis denotes the formation of five conglomerates according to similarity, where the substratum and reef cover are the possible determinant variables. The four predominant species (D. mexicanum, P. unifascialis, Toxopneustes roseus and Hesperocidaris asteriscus), whose densities were compared with those of other sites of the Oriental Tropical Pacific, show, in general, inferior values for Echinoidea and intermediate values for the Asteroidea. For the specific case of D. mexicanum, there are differences in the densities between localities, depths, and time of year, and the mean value obtained of 1.45±0.60 ind m-2 was low compared to densities recorded in other zones. Also, it was observed that in some localities, such as Playa Coral, Caleta de Chon, Punta del Cerro Colorado, and Zacatoso, the sea urchin densities increased considerably during the rainy season, and these high densities maintain a positive correlation with coral cover, which is indicative of a balanced ecosystem. It was also detected that in localities close to Acapulco, which undergo more tourist activity, such as Isla Roqueta, Ensenada de Llantos, and Pichilingue, the diversity of echinoderms is lower (0.6 bits ind-2) and the abundance of D. mexicanum is higher. These results, plus those of other studies at Acapulco Bay, suggest that pertinent actions should be taken to avoid similar phase shifts on reefs of Ixtapa-Zihuatanejo, which are currently considered to be the best developed in the Mexican Tropical Pacific.
对来自Zihuatanejo和Acapulco, Guerrero的棘皮动物的了解目前仅限于分类列表。这项工作试图利用50米长1米宽的带样来更好地表征该地区与珊瑚礁相关的这些生物群落。2004年进行了两次采样，一次在雨季，另一次在旱季。共发现10种，其中星总科3种，棘总科6种，全息总科1种。13个研究点的多样性平均值(1.036 bit - ind-1)低于最大可能多样性值(3.322 bit - ind-1)，这可能是由于黑海胆Diadema mexicanum和海星Phataria unifascialis的优势，其密度分别为1.45±0.60 ind- m2和0.12±0.02 ind- m2。多样性最高与低潮相关，不同地区间差异不大。多维尺度分析得到的棘皮动物物种组成的空间排列表明，根据相似性，形成了5个砾岩，其中基质和礁盖是可能的决定变量。4种优势种(墨西哥沙蚤、单股沙蚤、玫瑰弓形虫和星形狐尾虫)的密度与热带太平洋东部其他地点的密度比较，结果表明，棘总目密度较低，星形总目密度居中。在不同地区、不同深度、不同季节，墨西哥沙蚤的密度均存在差异，平均密度为1.45±0.60 ind m-2，低于其他地区。此外，在Playa Coral、Caleta de Chon、Punta del Cerro Colorado和Zacatoso等一些地方，海胆密度在雨季显著增加，并且这些高密度与珊瑚覆盖率保持正相关，这表明生态系统平衡。在靠近阿卡普尔科旅游活动较多的地区，如Isla Roqueta、Ensenada de Llantos和Pichilingue，棘皮动物的多样性较低(0.6 bits / 2)，而D. mexicanum的丰度较高。这些结果，加上阿卡普尔科湾的其他研究结果，表明应该采取适当的行动，以避免伊斯塔帕-齐华塔内霍的珊瑚礁发生类似的相变，目前被认为是墨西哥热带太平洋中发展最好的珊瑚礁。

Morphological, ecological and zoogeographical information of three gobiid species of the genus Bathygobius (Pisces: Gobiidae) found in the Colombian Caribbean is presented; B Soporator is the most, common and eurytopic species, being found in a great variety of coastal habitats from estuaries to coralline areas; B. curacao and B. mystacium are rare and restricted to coralline areas, the former on soft bottoms of mangroves-sea grass beds ecotones, and the later on shallow, mixed sand and rocky bottoms. Taxonomic differentiation of the three species is difficult because of partial overlap in their diagnostic features.

Cienaga Grande de Santa Marta and Cienaga de Pajarales are the two main lagoons of the marginal lagunar system at the deltaic floodplain of Magdalena river, Caribbean coast of Colombia. A systematic surficial sampling was carried out in such lagoons and Salamanca coast. A sporadic sampling was done in other places of the deltaic plain. This paper presents results about grain size, mineralogy, organic matter contents, CaCO3 contents, X ray diffraction and chemical analysis of salts for sediments. Sedimentologic charts, distribution schemes and provenience notes are presented.

The macroalgal intertidal community at a tropical location (Punta de la Loma, Colombian Caribbean) was monitored at irregular intervals from 1992 to 1995. The highly diverse macroalgal community was relatively invariant in cover, taxa and biomass from small spatial scales (square centimeters). At larger spatial scales (square meters), however, there was a small but definitive seasonal pulse in dominance and composition. Sand intrusions over the rocky intertidal represents a strong disturbance reducing macroalgal cover during the dry season. Interannual variation was also detected. La Punta de la Loma appears to be influenced by the regional upwelling conditions.

The growth rate in ten months (September 1992 - july 1993) for 30 colonies of Acropora palmata along the northern zone of the Corales del Rosario national natural park, Colombian Caribbean, was determined. Three measuring techniques were used: by hand, by staining with alizarin red, and from growth bands by X ray photography. The annual growth estimate for the species in the Park was 5.2 ± 1.3 cm and was found inversely correlated to the size of the colony (lenght, width and height). The growth presented a spatial variation. The smallest growth was found at Caleta Island and the largest at Caribaru Island. The maximum growth rate was observed in the dry season (December-February). No significant differences were found between measurement by hand and by alizarin red. The X-ray technique showed that Acropora palmata does not present discernible annual growth bands.

Growth of sea fan Gorgonia ventalina (Linnaeus, 1758) (Cnidaria: Gorgoniidae) in the Santa Marta area, Colombian Caribbean. As a contribution to the biological knowledge about the sea fan Gorgonia ventalina and the use of this information as a tool to generate conservation and management strategies for this threatened species, a study about its annual growth rate, in different reef areas in Santa Marta and the National Natural Park Tayrona in the Colombian Caribbean took place. Manual measurements of 35 colonies were analyzed and images of 11 colonies were recorded in the beginning and in the end of the field stage. The annual growth rate varies among colonies and areas where measurements were taken. The average annual growth rate obtained with both of the methods was high and oscillated between 7.6 and 8.1 cm/year in height and between

A partir de sedimentos del Caribe colombiano se realizaron 31 aislamientos bacterianos en medio minimo de sales suplementado con hidrocarburos (ACPM o petroleo crudo) como unica fuente de carbono. Las cepas aisladas se sometieron a pruebas de seleccion en diferentes concentraciones de hidrocarburos y se escogieron once de ellas tolerantes al crudo y ACPM en un ambito del 1-8% v/v. Posteriormente, con las cepas seleccionadas, se conformo un cultivo bacteriano mixto y se evaluo su capacidad de degradar hidrocarburos en un ensayo a escala de laboratorio, con una concentracion del 2% v/v de ACPM en un periodo de 21 dias. Mediciones de la biomasa en Unidades Formadoras de Colonias (UFC)/mL fueron empleadas para elaborar la curva de crecimiento del cultivo mixto y la remocion de hidrocarburos se cuantifico por cromatografia de gases acoplada a masas. El cultivo mixto fue capaz de degradar el 68.6 % de los hidrocarburos alifaticos con preferencia de los n-alcanos de cadena larga (C12- C31), alcanzando un crecimiento maximo de 3.13 x 109 UFC / mL. Bajo el tiempo de observacion no se evidencio la degradacion de hidrocarburos aromaticos. Nueve de las once cepas se identificaron mediante los sistemas bioquimicos BBL crystal y API 50 CHB/E como bacterias correspondientes a los generos Klebsiella, Chromobacterium, Flavimonas, Enterobacter, Pseudomonas y Bacillus. Las cepas evaluadas tienen potencial enzimatico para degradar hidrocarburos y es necesario caracterizarlas a nivel molecular con el fin de formular un consorcio que sea efectivo para la aplicacion en campo
