Coral reefs are declining worldwide due to anthropogenic-driven environmental change. The foundation and health of these ecosystems rely on the harmonious functioning of all members of coral holobionts, i.e., cnidarian host, symbiotic microalgae, and associated microbiome. Coral stress responses often involve shifts in the taxonomic identity of the...

Coral reefs are beginning to experience conditions unlike any in recent history. Understanding ecosystem function on future reefs will require reassessing ecological processes under novel environmental regimes. For many coastal reefs, severely degraded water quality will be a hallmark of these novel regimes. While herbivory has traditionally been c...

El deterioro de las propiedades ópticas del agua, o aumento de turbidez, debido a perturbaciones antropogénicas es un fenómenogeneralizado en zonas costeras. Los efectos sobre el ambiente lumínico submarino y la fisiología de corales simbióticos, quedependen principalmente de la luz para sobrevivir y mantener elevada calcificación, han sido poco ex...

Coral reefs inside Cartagena Bay have disappeared, largely due to the constant discharge of contaminated, sediment-rich freshwater from the Dique Channel. Recently, which might be the last healthy coral reef in the bay was found between Bocachica and Barú. Despite the unfavorable conditions for coral development, this reef exhibits an average coral...

La avifauna de Malpelo ha sido poco estudiada porque la Isla es remota, de difícil acceso y estuvo deshabitada hasta 1986. Pese a que existen registros de aves publicados desde finales del siglo XIX, casi todos los estudios han consistido en anotaciones esporádicas sobre la fauna terrestre. Entre finales del año 2003 y finales del 2006 realizamos o...

Las diferencias en la dieta entre individuos en aves marinas con dimorfismo sexual han sido atribuidas a las diferencias en tamaño corporal y se ha postulado que el sexo de mayor tamaño consume una mayor cantidad de alimento y presas más grandes. Para examinar esta hipótesis, estudiamos la ecología trófica del piquero de nazca (Sula granti) en la I...

Degradation of water optical properties due to anthropogenic disturbances is a common phenomenon in coastal waters globally. Although this condition is associated with multiple drivers that affect corals health in multiple ways, its effect on light availability and photosynthetic energy acquisition has been largely neglected. Here, we describe how...

Coral reefs are undergoing degradation due to overexploitation, pollution, and climate change. Management and restoration efforts require that we gain a better understanding of the complex interactions between corals, their microbiomes, and their environment. For this purpose, Varadero Reef near Cartagena, Colombia, serves as an informative study s...

Coral reefs are commonly associated with oligotrophic, well-illuminated waters. In 2013, a healthy coral reef was discovered in one of the least expected places within the Colombian Caribbean: at the entrance of Cartagena Bay, a highly-polluted system that receives industrial and sewage waste, as well as high sediment and freshwater loads from an o...

Coral reefs supply millions of people with ecosystem goods and services, especially those living along tropical coastlines. Unfortunately, these ecosystems are disappearing at an alarming pace. In the Caribbean, the rate of coral loss is high (5.5 – 9.2% per year) and constant. In 2013, a healthy coral reef was discovered in one of the least expect...

Recently, we found what might be one of the best coral reefs on the continental shelf of Colombia in terms of coral cover (up to 80 %) and dominated by Orbicella spp. (Fig. 1). The total extension of this formation is close to 1 km2. A well-developed coral reef in such a highly degraded environment is contrary to expectations. With massive coral co...

Most of the known food webs are based on organic compounds provided by photoautotrophic organisms. The terrestrial ecosystem of Malpelo Island (Colombia) seems to be an exception, however, since it supports several trophic guilds without hosting an adequate amount of primary producers. It has been suggested that this apparent paradox might be expla...

The associations between anemones and hermit crabs have been broadly documented, since they are considered a typical case of mutualism. The genus Dardanus has been one of the most studied cases due to the active transference of its associated anemones (e.g. Ross, 1970), from which it is believed that the hermit crab receives benefit by camouflage,...
