“…In this way, urbanisation is a multifaceted, heterogeneous and complex phenomenon and it is highly contextual [5]. Its ecological impacts are extreme and often irreparable such as habitat loss, spread of invasive species, disappearance of foundation species, changes in biodiversity, productivity and community composition, settlement of ruderal species and proliferation of jellyfish and toxic algae [4,[6][7][8][9]. Urban impacts have been deeply evaluated on terrestrial and freshwater ecosystems, showing big modifications on their structure and function [4,10].…”

The role of urbanisation in affecting Mytilus galloprovincialis

Urbanisation is considered as one of the most critical and widespread threats to coastal marine ecosystems. The aim of this study was to compare the density, percentage cover, thickness of clumps, condition index and size-frequency distribution of Mytilus galloprovincialis between urban and non-urban shores, at nested spatial scales, in the Northern Portuguese coast. M. galloprovincialis was selected as model because it is economically and ecologically relevant. Moreover, the relationship between mussel size and the other variables (i.e. density, percentage cover, thickness and condition index) were investigated. Mussels on urban shores showed a smaller density and a greater frequency of larger individuals. A significant negative correlation between mussel length with density and with thickness of clumps was also found. Our results seem to indicate that recruitment has declined on urban shores and, as a result, intraspecific competition is also smaller, leading to more resources being available for a fewer individuals which can reach larger sizes. As mussel beds support a great biodiversity of invertebrates and provide many ecosystem services, urbanisation may have indirect effects on communities associated with mussels. Understanding the vulnerability of mussel beds to urbanisation could inform management.

“…Noise and light pollution have also become a growing global concern due to their damaging effects on aquatic species. These kinds of pollution are caused by urbanization and industrialization of coastal zones, recreational boating, seismic and drilling operations at sea (Depledge et al, 2010;Bugnot et al, 2019). They can cause ecological shifts in natural communities, cognitive impairment and affect the underwater behavior of organisms (Buxton et al, 2017;Leduc et al, 2021).…”

Pollutants in the South Atlantic Ocean: Sources, Knowledge Gaps and Perspectives for the Decade of Ocean Science

The current manuscript presents the main issues related to the “Clean Ocean” outcome that arose from the Regional South Atlantic (SA) Planning Workshop for the UN Decade of Ocean Science and five Brazilian Regional Planning Workshops. An interdisciplinary and trans-sectoral group constituted by the academia, non-governmental agencies, the private sector, decision-makers, the navy, and local communities discussed the main anthropogenic drivers compromising the current environmental status of the SA and its ecological services, and debated the main research gaps, priorities and needs for improving technical and structural capacities in order to roadmap the Brazilian actions for the Decade of Ocean Science. The aim of this review is to contribute to a social solution-driven understanding of the ocean ecosystems, to create conditions to promote sustainable development and to secure a clean, healthy ocean. We are proposing a list of actions to be implemented by the Decade of Ocean Science that will have the pivotal role to promote technical and scientific capacity development, increase research infrastructure and institutional frameworks, develop national public policies aimed at reducing the input of pollutants and management of impacts, and warranting food security and ecosystem health. The earlier the actions in controlling pollutants are implemented, along with the identification of key sources and prevention of crossing of thresholds will help to avert worst-case scenarios, reducing the socio-economic disparities of impacts across nations and social groups and supporting the sustainable development of a pollutant-free ocean.

“…As human populations grow, so too will impacts on coastal ecosystems. Numerous studies have documented that development and urbanization of marine coastal zones result in impacts that cross terrestrial, freshwater and marine realms, resulting in damage to ecosystem services provided by these regions [13,[21][22][23][24][25].…”

Impacts of stormwater on coastal ecosystems: the need to match the scales of management objectives and solutions

Despite their limited area relative to the global ocean, coastal zones—the regions where land meets the sea—play a disproportionately important role in generating ecosystem services. However, coastal ecosystems are under increasing pressure from human populations. In particular, urban stormwater is an increasingly important threat to the integrity of coastal systems. Urban catchments exhibit altered flow regimes that impact ecosystem processes and coastal foodwebs. In addition, urban stormwater contains complex and unpredictable mixtures of chemicals that result in a multitude of lethal and sublethal impacts on species in coastal systems. Along the western coast of the United States, we estimate that hundreds of billions of kilograms of suspended solids flow off land surfaces and enter the Northern California Current each year. However, 70% of this pollution could be addressed by treating only 1.35% of the land area. Determining how to prioritize treatment of stormwater in this region requires a clear articulation of objectives—spatial distribution of appropriate management actions is dependent on the life histories of species, and management schemes optimized for one species may not achieve desired objectives for other species. In particular, we highlight that the scale of stormwater interventions must match the ecological scale relevant to species targeted by management. In many cases, management and policy will require mechanisms in order to ensure that local actions scale-up to efficiently and effectively achieve management objectives. In the face of rapid urbanization of coastal zones, failure to consider the match of management and ecological scales will result in the continued decline of coastal ecosystems and the species they support. This article is part of the theme issue ‘Integrative research perspectives on marine conservation’.
