Towards a framework for assessment and management of cumulative human impacts on marine food webs

Abstract: Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for… Show more

“…Moorings using anchors (anchoring) and fixed weights moorings (mooring) are one of the main causes of anthropogenic disturbances within seagrass meadows (Walker et al 1989, Hastings et al 1995, Montefalcone et al 2008, Boudouresque et al 2012, Demers et al 2013, Giakoumi et al 2015. Gaps caused by trawling and the anchoring of large boats have been found along the Mediterranean coast (Francour et al 1999, Leriche et al 2006) and nearshore mooring scars can increase the loss of sedimentary organic carbon stores (Serrano et al 2016).…”

“…Human activities, such as coastal development, trawling, anchoring, fish farms, are well known to directly modify P. oceanica meadow structure at all depths (Boudouresque et al, 2009;Giakoumi et al, 2015), but such effects are less evident within the 35-43 m bathymetric range (Pasqualini et al, 1998). As in the case of naturally-occurring patches of the seagrass, patches resulting from anthropogenic activities can be clearly identified at a large spatial scale according to their size and shape Clabaut et al, 2014;Pasqualini et al, 1999).…”

“…The understanding of biological invasion processes and their impacts on native marine biodiversity and ecosystems, as well as the quantification and mapping of the impacts of invasive alien species, are considered as prerequisites for the prioritization of conservation management actions (Blackburn et al 2011. Biological invasions are being widely disregarded when planning for conservation in the marine environment, although their explicit consideration can significantly alter spatial conservation priorities (Giakoumi et al 2016). Additional management actions aimed at prevention as well as the mitigation of the impact of invasive species are required at all levels.…”

“…Another important issue that has been largely overlooked by the scientific community is how to account for biological invasions in marine conservation planning (Giakoumi et al 2016). This globally important threat to biodiversity, often facilitated by climate change, needs to be mitigated through specific conservation actions.…”
