Article Reference Valuation of ecosystem services in marine protected areas: A comprehensive review of methods and needed developments
Effectively managing Marine Protected Areas (MPAs) requires recognising and understanding the fundamental services offered by marine ecosystems and the socio-economic consequences that their changes will have. A systematic literature review was performed to generate a first in-detail screening and assessment of monetary and non-monetary methods for the valuation of ecosystem services (ES) and their application in MPAs and MPA networks. A total of 100 peer-reviewed papers on ES valuation within MPAs and MPA networks were identified and analysed. Valuation methods can be classified into nine monetary and seven non-monetary methodologies. There is a predominant use of monetary valuation methodologies, especially stated preference methods. However, combining monetary with non-monetary valuation approaches can provide deeper insights into the underlying reasons for assigning values to ES and offer enhanced opportunities to capture the value of services that may be challenging to express solely in monetary terms. Besides, the review underscores the gaps in assessment methodologies, particularly in addressing supporting and regulating ES, as well as non-use and option values related to MPAs, underscoring the need for innovative approaches to overcome challenges in capturing these essential components of marine ecosystems.

Article Reference Variability in ostracod communities (Crustacea, Ostracoda) in connected and isolated tropical floodplain lakes
Floodplains mostly consist of primary and secondary riverbeds, connecting channels and lakes that are either isolated from rivers and channels for most of the year, or lakes that are connected to rivers and channels for most (or all) of the year. We hypothesize that the differences in invertebrate communities, as calculated by beta-diversities, will be higher in isolated than in connected lakes. We use ostracod communities in the pleuston of the floating macrophyte Eichhornia crassipes in the Upper Paraná River floodplain to test this hypothesis. We have observed significant differences in species composition between the two types of lakes. However, although beta diversity values are indeed slightly higher in isolated than in connected lakes, these differences are not significant. This lack of clear effect of isolation on beta diversity could be owing to the fact that the period of isolation since the last homogenizing flood pulse had not been long enough, or because differences in degree of isolation become altogether insignificant in periods of low water flow.

Article Reference Variability of Suspended Particulate Matter in the Bohai Sea from the Geostationary Ocean Color Imager (GOCI)
This study assesses the performance of the Geostationary Ocean Imager (GOCI) for mapping of suspended particulate matter in the Bohai Sea, a turbid water region. GOCI imagery for remote sensing reflectance and Total Suspended Solids (TSS) is analysed in detail for two days in June 2011 (8 images per day). Both instantaneous and daily composite maps are considered and a comparison is made with corresponding reflectance and TSS products from MODIS-AQUA. Results show TSS distributions corresponding to previous studies of the region. The advantage of the higher acquisition frequency (8 images/day instead of 1) offered by GOCI is clearly demonstrated in the daily composite which is more complete during this period of scattered but moving clouds. Consideration of temporal variation over the day indicates low natural variability but some artificial variability from processing errors - this analysis provides a first indication of how the higher frequency of data from geostationary ocean colour could lead to improved data quality control via temporal coherency outlier detection. While there is room for improvement on the GOCI calibration, atmospheric correction and retrieval algorithms, the current study suggests that the GOCI data can already be used now to study qualitatively sediment dynamics except in the extremely turbid waters which are masked out of the current dataset. In a wider context, it is considered that the technical challenges of geostationary ocean colour have been met by the GOCI concept, and, notwithstanding potential improvements on the concept and data processing methods, it is recommended that this mission serve as a model for future geostationary ocean colour sensors over Europe/Africa and the Americas.

Article Reference Variation in ecosystem services within biogenic reefs: The role of reef-building species under distinct hydrodynamic conditions
To enhance the climate resilience of coastlines, measures are being implemented to protect and restore coastal ecosystems, such as biogenic reefs and dunes. These measures, known as Nature-based Solutions (NbS), provide protection against storms, coastal erosion, and flooding. They are also recognised for increasing biodiversity and delivering a range of ecosystem services (ES). This study investigated the ES provided by biogenic reefs composed of two reef-building species (Mytilus edulis and Lanice conchilega) under distinct hydrodynamic conditions. Three ES were assessed at two sites in the Belgian part of the North Sea: (1) coastal protection, (2) carbon sequestration, and (3) water quality regulation. The two sites have different hydrodynamic conditions due to their relative locations in relation to local sandbanks, making one site more exposed and the other more sheltered. The ES were quantified and monetised using in-situ measurements and literature data based on the SUstainable Marine Ecosystem Services (SUMES) model. The results suggest that the provision of ES in biogenic reefs is determined by multiple factors, including environmental conditions (e.g. hydrodynamics) and reefbuilding species. (1) Sediment accumulation was only observed under low hydrodynamic conditions, due to the higher settlement success of M. edulis and the presence of L. conchilega. (2) M. edulis “produces” carbon under both low and high hydrodynamic conditions, due to high respiration and biocalcification rates. However, low hydrodynamic conditions are more conducive to carbon burial, thus enhancing carbon sequestration. (3) M. edulis patches exhibited higher denitrification rates under low hydrodynamic conditions than under high hydrodynamic conditions or in L. conchilega patches, due to divergent macrobenthic functional diversity. In conclusion, the level of ES provision is determined by location and associated environmental conditions, as well as temporal and spatial variation in biogenic reefs and the physiological characteristics of reef builders. Therefore, both aspects need to be carefully considered when planning coastal protection measures and determining the provision of ES. Finally, when implementing NbS along high-energy coastlines, sheltered sites should be prioritised.
