Ecosystem services classification: A systems ecology perspective of the cascade framework

Ecological Indicators, Год журнала: 2016, Номер 74, С. 392 - 402

Опубликована: Дек. 9, 2016

Ecosystem services research faces several challenges stemming from the plurality of interpretations classifications and terminologies. In this paper we identify two main with current ecosystem classification systems: i) inconsistency across concepts, terminology definitions, and; ii) mix up processes end-state benefits, or flows assets. Although different service definitions can be valuable for enriching landscape, it is necessary to address existing ambiguity improve comparability among ecosystem-service-based approaches. Using cascade framework as a reference, Systems Ecology theoretical underpinning, aim typologies. The links ecological elements human well-being following pattern similar production chain. long-established discipline which provides insight into complex relationships between people environment. We present refreshed conceptualization support assessment techniques measurement. combine notions biomass, information interaction system ecology, clarify terminology. argue that should defined interactions (i.e. processes) produce change in well-being, while components goods, i.e. countable biomass units, are only proxies such changes. Furthermore, re-interpretation related applied research, where more emphasis needed on underpinning complexity system.

Relationship between ecological condition and ecosystem services in European rivers, lakes and coastal waters

The Science of The Total Environment, Год журнала: 2019, Номер 671, С. 452 - 465

Опубликована: Март 12, 2019

We quantify main ecosystem services (i.e. the contribution of ecosystems to human well-being) provided by rivers, lakes, coastal waters and connected (riparian areas floodplains) in Europe, including water provisioning, purification, erosion prevention, flood protection, recreation. show European maps service capacity, flow (actual use), sustainability efficiency. Then we explore relationship between condition at scale, considering ecological status aquatic ecosystems, reported under EU Water Framework Directive, as a measure integrity biodiversity. Our results indicate that higher delivery regulating cultural analysed is mostly correlated with better conditions ecosystems. Conversely, use provisioning can result pressures on ecosystem. This suggests importance maintaining good ensure future. These continental although limited analysis, might be relevant consider when investing protection restoration called for current policy Biodiversity Strategy United Nations Sustainable Development Goals.

Historical changes of the Mediterranean Sea ecosystem: modelling the role and impact of primary productivity and fisheries changes over time

Scientific Reports, Год журнала: 2017, Номер 7(1)

Опубликована: Март 14, 2017

The Mediterranean Sea has been defined "under siege" because of intense pressures from multiple human activities; yet there is still insufficient information on the cumulative impact these stressors ecosystem and its resources. We evaluate how historical (1950-2011) trends various ecosystems groups/species have impacted by changes in primary productivity (PP) combined with fishing pressure. investigate whole using a food web modelling approach. Results indicate that both PP pressure played an important role driving species dynamics. Yet, was strongest driver upon ecosystem. This highlights importance bottom-up processes controlling biological characteristics region. observe reduction abundance fish (~34%, including commercial non-commercial) top predators (~41%), increases organisms at bottom (~23%). Ecological indicators, such as community biomass, trophic levels, catch diversity reflect show overall degradation over time. Since climate change are expected to intensify Sea, this study constitutes baseline reference for stepping forward assessing future management basin.

Marine heat waves in the Mediterranean Sea: An assessment from the surface to the subsurface to meet national needs

Frontiers in Marine Science, Год журнала: 2023, Номер 10

Опубликована: Янв. 30, 2023

In the Mediterranean Sea, marine ecosystems and resource-based economy are shared among many countries, making this a regional sea of important geopolitical economic stakes. Over last decades, heat waves (MHWs) in Sea have caused mass-mortality events various species critical losses for seafood industries. MHWs expected to become more intense, longer frequent through anthropogenic warming. This study proposes better understand how much each country’s Exclusive Economic Zone (EEZ) waters may be affected by MHW changes, contribute decision support management adaptation at national scale. The variability surface subsurface is assessed over 1987-2019 period EEZs, which ocean areas where sovereign states special rights. Combining high-resolution satellite observations reanalysis, temperature content used define MHWs. characteristics selected highlight differences between extreme events. frequency higher than has significantly increased most EEZs both subsurface, while duration all EEZs. intensities decrease with depth, its increase time disparate throughout basin. maximum intensity displays significant positive trends values western it reaches Levantine contrast, cumulative exhibits trend eastern subsurface. choice “Top-Ten” list shows that impact different depending on emphasizing need consider avoid focusing only surface. Overall, results necessity strengthening observing systems establish local-scale risk assessments respond diverse stakeholder needs.

Ecosystem services accounts: Valuing the actual flow of nature-based recreation from ecosystems to people

Ecological Modelling, Год журнала: 2018, Номер 392, С. 196 - 211

Опубликована: Дек. 4, 2018

Natural capital accounting aims to measure changes in the stock of natural assets (i.e., soil, air, water and all living things) integrate value ecosystem services into systems that will contribute better ecosystems management. This study develops accounts at European Union level, using nature-based recreation as a case following current international framework: System Environmental-Economic Accounting - Experimental Ecosystem (SEEA EEA). We adapt different biophysical socio-economic models, illustrating workflow necessary for accounts: from assessment an economic valuation compilation tables. The is based on spatially explicit models assessing components services: potential, demand actual flow.

Small pelagic fish in the new millennium: A bottom-up view of global research effort

Progress In Oceanography, Год журнала: 2020, Номер 191, С. 102494 - 102494

Small pelagic fish (SPF) play extremely important ecological roles in marine ecosystems, form some of the most economically valuable fisheries resources, and a vital role global food security. Due to their short generation times tight coupling lower trophic levels, populations SPF display large boom-and-bust dynamics that are closely linked climate variability. To reveal emerging research trends on as opposed more recently published, ecosystem-specific reviews SPF, we reviewed literature published two, 6-year periods new millennium (2001–2006, 2011–2016) straddling publication large, review 2009. We explored intrinsic extrinsic (bottom-up) factors influencing such anchovies, sardines, herrings sprats within sub-order Clupeidae. Published efforts 16 different biogeographic ocean regions were compiled (more than 900 studies) compared identify i) milestones advances our understanding, ii) iii) remaining gaps knowledge.
