Abstract Environmental DNA (eDNA) analysis is a revolutionary method to monitor marine biodiversity from animal traces. Examining the capacity of eDNA provide accurate measures in species‐rich ecosystems such as coral reefs prerequisite for their application long‐term monitoring. Here, we surveyed two Colombian tropical reefs, island Providencia and Gayraca Bay near Santa Marta, using underwater visual census (UVC) methods. We collected large quantity surface water (30 L per filter) above...
Abstract Seagrass ecosystems rank amongst the most efficient natural carbon sinks on earth, sequestering CO 2 through photosynthesis and storing organic (C org ) underneath their soils for millennia thereby, mitigating climate change. However, estimates of C stocks accumulation rates in seagrass meadows (blue carbon) are restricted to few regions, further information spatial variability is required derive robust global estimates. Here we studied soil across Colombian Caribbean. We estimated...
Natural processes such as upwelling of deeper-water masses change the physical-chemical conditions water column creating localized ocean acidification events that can have an impact on natural communities. This study was performed in a coral reef system archetypical bay within Tayrona National Park (PNNT) (Colombia), and aimed to quantify net calcification rates foundational species temporal context (6 months) taking into account dynamics seasonal influence area. Net fragments were obtained...
Hurricanes are important natural destructive forces for coral reefs that can change the structural component of habitat. On November 16th, 2020, hurricane Iota passed ~10 km north islands Providencia and Santa Catalina with sustained winds a category 5 hurricane. The purpose this study was to document magnitude impact on around two weeks after hit, as part “Operación Cangrejo Negro”. Visual assessments were performed at 11 representative reef formations between 2 17 m depth. Estimates...
Introducción: Los protistas del género Labyrinthula causan la denominada “Enfermedad desgaste” en el pasto marino, Thalassia testudinum. Desde 2008 los monitoreos Caribe colombiano han mostrado variación espacial y temporal incidencia de enfermedad, pero sin alta mortalidad observada otras regiones mundo. Objetivo: Analizar algunos parámetros epidemiológicos T. testudinum comparar metabolitos entre plantas sanas e infectadas. Métodos: Registramos severidad, prevalencia esta enfermedad Parque...
Seagrass meadows have stood out for being very effective fixing atmospheric carbon, among others, due to their ability produce plant biomass. Therefore, the values of shoot density (m2), biomass (cores) and carbon present in 12 locations with Thalassia testudinum at Colombian Caribbean (La Guajira San Andrés Island) were quantified. The biological samples processed laboratory until obtaining aerial, underground total dry weight, estimation was stablishing from a ratio 35 % Statistical tests...
El Parque Nacional Natural Tayrona, ubicado en la costa Caribe colombiana, está formado por una de acantilados y bahías su mitad occidental, cuyo interior se encuentran formaciones coralinas. En 2005 encontró formación bahía Cinto dominada Acropora palmata afectada enfermedad cuyas lesiones eran similares a las causadas White Pox. Durante los siguientes dos años realizó un seguimiento 15 mediante registro fotográfico tres ocasiones distintas (mayo agosto 2006 marzo 2007), coincidiendo con...
