Growth rates of five coral species across a strong environmental gradient in the Colombian Caribbean

Abstract Coral calcification is critical for reef growth and highly dependent on environmental conditions. Yet, little known about how corals calcify under sub-optimal conditions (e.g., turbid waters, high nutrients, sedimentation) or coral in understudied regions such as the Colombian Caribbean. We therefore assessed linear extension rates of five species across an inshore-to-offshore gradient A suite variables (temperature, light intensity, visibility, pH, nutrients) measured during rainy season (May – November 2022) demonstrated more inshore compared to offshore. Across all species, were 59% 37% lower offshore midshore sites, respectively. massive calcified up 92% than branching but susceptible heat stress However, had reduced survival due extreme climatic events (i.e., bleaching, hurricanes). comparison with published wider Caribbean revealed that grow 11 times those while generally have similar rates, this finding may been influenced by fragment size and/or stress. Our findings indicate present-day conditions, coupled frequent events, will favor over areas This suggests a possible shift towards faster calcifying future communities, possibly exacerbating ongoing regional decline last decades.

The decline of coral reefs has increased interest in ecological restoration. Due to the scarcity gardening projects Eastern Tropical Pacific, improving our understanding such techniques is key. We report results using branching Pocillopora spp. and massive species ( Pavona gigantea , clavus Porites lobata ) an upwelling area Costa Rica. examined whether nursery type influenced survival growth, how environmental conditions shaped monitored growth fragments n = 334) microfragments P. [ 148], 37], 66]) over 11 months. Survival at end period was 51% for spp., 59% 55% 17% with a after cease maintenance caused by COVID-19 lockdown. floating nurseries exhibited higher (7.52 ± 1.98 6.64 2.91 cm yr -1 than A-frame (4.16 2.35 ), which suggests benefits suspending fragments. For 1.92-4.66 2 were affected pigmentation loss, causing partial tissue loss mortality. Our point towards acclimation local conditions, show need develop site-specific cost-efficient species, allowing multi-species approach ensure long-term ecosystem recovery.
