Society relies on intact marine ecosystems for ecosystem services such as nutrition, livelihoods, health and well‐being. Yet, to obtain these benefits, we carry out activities, introducing pressures to ecosystems, damaging and degrading habitats and reducing their capacity to optimally provide ecosystem services. Biodiversity and ecosystem services...

The Philippine coastal marine ecosystem provides many Ecosystem Services (ES) and is a region where coastal communities are closely dependent on the sea. Previous ES studies focus mainly on biophysical and economic assessments with limited studies about Cultural Ecosystem Services (CES), particularly in the Philippines. Here, we present the CES pro...

Ecosystem service potential Confidence scores Evidence gaps particularly scarce, especially in SE Asia. Given the growing coastal population and expansion in blue economy sectors in SE Asia, evidence to support effective marine planning, such as ecosystem service assessments, is urgently needed. Data deficiencies for marine systems, especially (but...

The aspirations for natural capital and ecosystem service approaches to support environmental decision-making have not been fully realised in terms of their actual application in policy and management contexts. Application of the natural capital approach requires a range of methods, which as yet have not been fully tested in the context of decision...

Marine Protected Areas (MPAs) and networks of MPAs are being implemented globally as a spatial management tool for achieving conservation objectives. There has been considerable progress in reaching the prescribed 10% protected area target for 2020, outlined in the Convention on Biological Diversity Aichi Target 11 and the United Nations Sustainabl...

The Convention on Biological Diversity (CBD) Aichi Target 11 states that, “by 2020, at least 17 per cent of terrestrial and inland water, and 10 per cent of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services, are conserved through effectively and equitably managed, ecologically representative...

The ecosystem services approach is widely recognised as a concept, but more attention must be given to the development of tools to facilitate practical implementation if the approach is to become more widely used to support decision-making. A key component of natural resource management is understanding the implications of changing levels of pressu...

Marine protected areas (MPAs) are a management tool used to respond to human-derived threats in marine ecosystems. Historically, MPAs have been established on an individual ad hoc basis, rather than through a systematic, planned process. However, high levels of functional and spatial connectivity within marine ecosystems have led to the suggestion...

The coastal zone supports a wide range and high density of activities including fisheries, recreation, energy, ports and shipping, communication infrastructure and aggregate extraction, which must co-exist with each other and with wider social and environmental management objectives. The ecosystem services approach has the potential to support plan...

This chapter examines the potential relationship between ecosystem services provided by coastal ecosystems and the design and management of Marine Protected Areas (MPAs). While all coastal and marine habitats provide a range of ecosystem services, the implementation and management of an MPA may result in improvements in the quality or supply of an...

We augment discussions about the Good Environmental Status of the North Sea by developing two extreme visions and assessing their societal benefits. One vision (‘Then’) assumes restoration of benthic functioning; we contend that trawling had already degraded the southern North Sea a century ago. Available information is used to speculate about bent...

Aim Ecologists seeking to describe patterns at ever larger scales require compilations of data on the global abundance and distribution of species. Comparable compilations of biological data are needed to elucidate the mechanisms behind these patterns, but have received far less attention. We assess the availability of biological data across an ent...

It is well documented that bottom towed fishing gear can negatively and substantially influence benthic communities through changes in species composition, trophic structure and habitat complexity (de Groot & Lindeboom, 1994; Dayton et al., 1995; Kaiser & Spencer, 1996; Blyth et al., 2004; Hiddink et al., 2006). Such effects caused by fishing gear...

During recent decades anthropogenic activities have dramatically impacted the Black Sea ecosystem. High levels of riverine nutrient input during the 1970s and 1980s caused eutrophic conditions including intense algal blooms resulting in hypoxia and the subsequent collapse of benthic habitats on the northwestern shelf. Intense fishing pressure also...

INTRODUCTION What are the current human impacts on rocky shores and what will the ecosystem be like by the year 2025? This assessment builds on the review of Thompson et al. (2002), but provides a more global perspective and outlines actions that are needed to counter threats to rocky shores. The chapter begins by briefly describing the characteris...

European society is experiencing unprecedented changes triggered by expansion of the European Union, the fall of Communism, economic growth and the onset of globalisation. Europe's regional seas, the Baltic, Black Sea, Mediterranean and North-East Atlantic (including the North Sea), provide key goods and services to the human population but have su...

Long-term research in the western English Channel, undertaken by the marine laboratories in Plymouth, is described and details of survey methods, sites, and time series given in this chapter. Major findings are summarized and their limitations outlined. Current research, with recent reestablishment and expansion of many sampling programmes, is pres...

Polyps of the corallimorpharian Rhodactis rhodostoma (Ehrenberg, 1934) form aggregations that monopolise patches of space on the shallow reef flats of some Red Sea coral reefs. Some of these polyps bear specialised bulbous marginal tentacles (BMTs) where they contact cnidarian competitors. BMTs differ from the normally filiform marginal tentacles (...

The corallimorpharian Rhodactis rhodostoma (Ehrenberg, 1934) forms aggregations that dominate patches on some coral reef flats in the Red Sea. The outcomes and mechanisms of competition for space between this corallimorpharian and other sessile organisms are poorly understood. Polyps of R. rhodostoma were observed to overgrow zoanthids, hydrozoan c...
