“…beds can be considered as coastal areas with high MES capacity, although relatively limited in space (0.5% of the total study area). Seagrass meadows play an essential ecological role and are fundamental for supporting biodiversity conservation, nursery and habitat conservation, provision nutrient cycling and are responsible for photosynthesis processes (Campagne et al, 2015). In this context, the presented model can inform planners on the ecological functioning of coastal areas and provide baseline information for the development of ecosystem-based management strategies, required by the MSFD.…”

This research presents a set of multi-objective spatial tools for sea planning and environmental management in the Adriatic Sea Basin. The tools address four objectives: 1) assessment of cumulative impacts from anthropogenic sea uses on environmental components of marine areas; 2) analysis of sea use conflicts; 3) 3-D hydrodynamic modelling of nutrient dispersion (nitrogen and phosphorus) from riverine sources in the Adriatic Sea Basin and 4) marine ecosystem services capacity assessment from seabed habitats based on an ES matrix approach. Geospatial modelling results were illustrated and analysed for three biogeographic subdivisions, Northern-Central-Southern Adriatic Sea. The paper discusses model results for their spatial implications, relevance for sea planning, limitations and concludes with an outlook towards the need for more integrated, multi-functional tools development for sea planning.

“…P. oceanica meadows have an important ecological but also economic value (Costanza et al ) estimated to 172 € m −2 yr −1 by Vassallo et al (), as they provide numerous ecosystem goods and services (Boudouresque et al ; Campagne et al ). P. oceanica meadows are ecosystem engineers that transform and stabilize the coastal environment (Boudouresque et al ).…”

“…The extent of the meadows of P. oceanica is decreasing (Boudouresque et al 2009;Marbà et al 2014;Telesca et al 2015), as most other seagrasses worldwide (Waycott et al 2009). P. oceanica meadows have an important ecological but also economic value (Costanza et al 1997) estimated to 172 € m −2 yr −1 by Vassallo et al (2013), as they provide numerous ecosystem goods and services (Boudouresque et al 2006;Campagne et al 2015).

Inter‐annual variations over a decade of primary production of the seagrass Posidonia oceanica

We acquired quasi‐continuous measurements of community gross primary production (GPP) by mass balance of O2 measured on a mooring, from August 2006 to October 2016 over a Posidonia oceanica meadow (10 m depth) in the Bay of Revellata (Corsica). Over the 2006–2016 period, annual GPP averaged 88 molO2 m−2 yr−1 and ranged from 61 to 108 molO2 m−2 yr−1. The 2 yr with the lowest annual GPP (2007 and 2015) were characterized by a low occurrence of fall–winter storms, probably leading to the accumulation of leaf litter in fall and early winter; we hypothesize this might have led to occultation of benthic macro‐algae. Among the other years, the inter‐annual variability of GPP was related to changes during the February–August period, as GPP was repeatable among years during the September–January period. For the February–August period, inter‐annual variations of GPP were correlated to chlorophyll a (Chl a), solar radiation (SR) and water temperature. Computed phytoplankton GPP corresponded to a small fraction of community GPP, so the relation between GPP and Chl a probably reflected inter‐annual variations of a common driver that we hypothesize to be nutrient inputs. The correlation of GPP with SR shows that light availability contributed to inter‐annual variations of the development of P. oceanica. The positive relation between GPP and temperature was consistent with the fact that the observed temperatures in the Bay of Revellata were during the study period within the comfort range for the growth of P. oceanica, despite an increase of water temperature of 0.7°C.

“…As relatively large and sometimes abundant benthic mesopredators, guitarfish have an important role in the trophic functioning of soft-sediment ecosystems (Kyne & Bennett 2002). As many guitarfish are found associated with seagrasses (Vaudo & Heithaus 2011), their presence presumably contributes to the healthy functioning of this habitat that is of very high ecosystem service value to humans (Campagne et al 2015). Guitarfishes are important prey items to non-human apex predators vital to ecosystem functioning, such as to bull (Carcharhinus leucas), sevengill (Notorynchus cepedianus), and great hammerhead (Sphyrna mokarran) sharks off southern Africa (Cliff & Dudley 1991, Ebert 1991, Cliff 1995.…”

Are guitarfishes the next sawfishes? Extinction risk and an urgent call for conservation action

Focusing on the most critical conservation priorities to prevent extinctions risks missing declines of lower priority taxa that may become tomorrow's emergency. Sawfishes (5 species) underwent catastrophic but largely unnoticed global declines in the latter part of the 20th century, and are now the subject of intensive research and conservation efforts. Guitarfishes (at least 55 species) share many characteristics with sawfishes: they are shark-like batoids with an often large body, prefer sedimentary habitats in warm shallow coastal waters exposed to intensive fisheries, and have high value fins and good quality meat. Guitarfishes represent a unique element of evolution and biodiversity and are vital components of complex coastal socio-ecological systems. Existing global IUCN Red List of Threatened Species assessments for nearly 60% of guitarfish species are 10 or more years old, and over 70% of species are either in threatened categories or Data Deficient. Recently described taxa not yet assessed include those likely to be at risk of extinction. Severe declines and localised extinctions have already been reported for guitarfishes. In notable contrast to sawfishes, total extinction of several guitarfish species is plausible given small distributions occurring solely in developing or least developed countries where conservation is highly challenging. Furthermore, species identification of guitarfishes is often problematic and they may lack the appeal often needed to promote conservation. To ensure that they do not follow the same trajectory as sawfishes, there is an urgent need for comprehensive and coordinated action on guitarfishes, which in many cases could integrate with sawfish conservation efforts.
