COMPARING K-DOMINANCE CURVES: YET ANOTHER SUGGESTION Boletín de Investigaciones
García,Camilo B..
A simple procedure is presented which facilitates the comparison of k-dominance curves and permits statistical comparison of replicated curves. Two indices are proposed, one for diversity (KDI) and one for dominance (KDO), which summarize the relationships in terms of diversity between one assemblage and all the others In a given set of data, as it is depicted by k-dominance curves.

ASPECTOS DE LA BIOLOGÍA DE PORTUNUS SPINICARPUS STIMPSON 1871 (DECAPODA: PORTUNIDAE) EN EL GOLFO DE SALAMANCA, CARIBE COLOMBIANO Boletín de Investigaciones
García,Camilo B.; Mendoza,Nardi.
Some vital statistics of the population of Portunus spinicarpus inhabiting the Golfo de Salamanca, Colombian Caribbean, are presented for the first time. Condition factor was found stable the year round, Von Bertalanffy growth parameters were estimated as L¥=38.6 mm, K= 2.5 year-1, to= -0.0573 year. Natural mortality was estimated as 4.62 year-1. P. spinicarpus seem to prefer deep waters and sand-muddy bottoms.

QUANTITATIVE DATA ON THE FOREST STRUCTURE OF A SMALL MANGROVE FORMATION IN THE BAY OF NENGUANGE, COLOMBIAN CARIBBEAN Boletín de Investigaciones
García,Camilo B..
Esta nota aporta información cuantitativa sobre la estructura de la pequeña formación de manglar que se encuentra sobre el costado oriental de la Bahía de Nenguange, Parque Nacional Natural Tayrona, con el fin de proporcionar un punto de comparación para eventuales estudios futuros. Se presentan datos sobre zonación, densidad, cubrimiento, altura, diámetro a la altura del pecho y área basal.

DYNAMICS OF A MACROALGAL ROCKY INTERTIDAL COMMUNITY IN THE COLOMBIAN CARIBBEAN Boletín de Investigaciones
García,Camilo B.; Díaz Pulido,Guillermo.
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 b 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.

RECRUITMENT PATTERNS OF SESSILE INVERTEBRATES ONTO FOULING PLATES IN THE BAY OF SANTA MARTA, COLOMBIAN CARIBBEAN Boletín de Investigaciones
García,Camilo B.; Salzwedel,Horst.
Recruitment of sessile invertebrates onto fouling plates immersed for consecutive two-week periods during one year was found to correlate with the local climatic regime. For selected species it was found that they recruited at significantly higher levels in certain local climatic periods, but that these periods are not necessarily the same for the different species. A conceptual model is presented in which the recruitment process is divided in a pre-settlement and a post-settlement phase. The model attempts to predict under which combination of global circumstances periods of increased recruitment are to be expected. Application of the model to the data at hand highlights where the research needs for the future are.

POSTLARVAS Y JUVENILES DE CAMARONES FARFANTEPENAEUS SPP Y XIPHOPENAEUS KROYERI EN LA BOCA DE LA BARRA (CIÉNAGA GRANDE DE SANTA MARTA), CARIBE COLOMBIANO Boletín de Investigaciones
López,Ángela C.; Criales,María M.; García,Camilo B..
Postlarvas y juveniles de los camarones Farfantepenaeus spp. y Xiphopenaeus kroyeri se colectaron en la Boca de la Barra (Ciénaga Grande de Santa Marta), mediante redes de canal fijas que se orientan con la marea. Se realizaron muestreos quincenales nocturnos durante un año (febrero 1998 - febrero 1999), correspondiendo a los períodos de luna nueva y luna llena, intercaladamente. Para Farfantepenaeus spp. se observó que las postlarvas tienden a presentarse durante la época seca del año y preferiblemente en la fase de luna llena, siendo la diferencia entre fases lunares estadísticamente significativa (test de Mann-Whitney, P<0.05). Los juveniles presentaron un comportamiento opuesto: hubo diferencias significativas (test de Mann-Whitney, P< 0.05)...
