“…Vast areas of vermetid reefs have recently died off in the Eastern Mediterranean which is thought to be due to widespread environmental changes in recent decades16. We fear that ocean acidification will accelerate this extinction process, exacerbating the effects of those additional stressors, such as pollution, that are known to damage these reefs56. Emergency conservation measures and a reduction in CO 2 emissions are both required to protect the reefs that remain.…”

Vermetids form reefs in sub-tropical and warm-temperate waters that protect coasts from erosion, regulate sediment transport and accumulation, serve as carbon sinks and provide habitat for other species. The gastropods that form these reefs brood encapsulated larvae; they are threatened by rapid environmental changes since their ability to disperse is very limited. We used transplant experiments along a natural CO2 gradient to assess ocean acidification effects on the reef-building gastropod Dendropoma petraeum. We found that although D. petraeum were able to reproduce and brood at elevated levels of CO2, recruitment success was adversely affected. Long-term exposure to acidified conditions predicted for the year 2100 and beyond caused shell dissolution and a significant increase in shell Mg content. Unless CO2 emissions are reduced and conservation measures taken, our results suggest these reefs are in danger of extinction within this century, with significant ecological and socioeconomic ramifications for coastal systems.

“…It has extensive coastal lines over the Pacific and Atlantic oceans (3800 km), several water bodies across the length and breadth of the country (18000 km of navigable rivers, 1800 lagoons, and 1900 reservoirs), a wide and recognized touristic offer, a growing integration into international markets and a positive international perception after the peace agreement signing [13,14]. Additionally, the solid growth of the main world markets, such as the United States market, the increase of ship moorings' demand and the construction of several small sports marinas and touristic facilities all over the world, has to be considered [5,7].…”

Abstract:The evaluation of urban development plans is a key concern of the strategic planning of the city of Cartagena de Indias (Colombia) due to the pressure exerted by both public and private sectors. Any strategic planning requirement deserves the inclusion of clear terms of coordination and cooperation among sectors, including local communities and the scientific sector. In this paper, we present a methodology for the sustainable evaluation of strategic nautical and naval projects for the development of the city of Cartagena de Indias. The methodology is based on the multicriteria technique Analytic Network Process, which allows considering political, socio-cultural and environmental aspects. The aim is to provide answers and guide the decision makers towards the optimal selection of strategies. Results provide some important insights into the overall conception of what sustainable evaluation means for the experts consulted. The procedure enhances participation and transparency and becomes a support for their decisions.

“…Benthic infaunal communities have been used as bioindicators of sediment health due their sensitivity to changes in contaminant concentrations in sediments, through ingestion, and uptake via pore water [26]. A considerable amount of literature exists on impacts to the composition of sediment infauna communities in ‘hotspots’ of contamination in coastal and estuarine systems [5,27,28]. However, rarely have these studies considered how the design and spatial allocation of infrastructure developments might reduce the future spatial extent of these impacts within marine parks.…”

Sediment Contaminants and Infauna Associated with Recreational Boating Structures in a Multi-Use Marine Park

Multi-use marine parks achieve conservation through spatial management of activities. Zoning of marine parks in New South Wales, Australia, includes high conservation areas and special purpose zones (SPZ) where maritime activities are concentrated. Although such measures geographically constrain anthropogenic impacts, we have limited understanding of potential ecological effects. We assessed sediment communities and contaminants adjacent to boating infrastructure (boat ramps, jetties and a marina) in a SPZ from the Clyde Estuary in Batemans Marine Park. Metal concentrations and fines content were elevated at boating structures compared to reference sites. Species richness was higher at sites with boating structures, where capitellid polychaetes and nematodes dominated the communities. Changes associated with boating structures were localised and did not extend beyond breakwalls or to reference sites outside the SPZ. The study highlights the benefits of appropriate zoning in a multi-use marine park and the potential to minimise stress on pristine areas through the application of spatial management.
