“…Mussel Density. Mussels transplanted on coarse shell material rather than bare sediment are less likely to aggregate into patches, resulting in a lower within-patch density (n/m 2 ) (Bertolini et al 2019;Capelle et al 2019). To determine if mussels aggregated closer together when transplanted on bare sediment in comparison with mussels transplanted on oyster shells or coir-nets, the within-patch density (n/m 2 ) was estimated after 21 days.…”

“…Soft sediment environments are challenging for mussel establishment because there is little suitable substrate available to which byssal threads can attach (Büttger et al 2008;Commito et al 2014). However, under very high spatfall densities, mussels are able to aggregate into extensive beds on sandy or muddy substrates by attaching their byssus threads to each other rather than to primary substratum (Reusch & Chapman 1997;Bertolini et al 2017Bertolini et al , 2019. This form of self-organisation enhances the persistence of the mussel bed and increases its resistance to wave disturbance (Liu et al 2014;de Paoli et al 2017).…”

Restoration of coastal ecosystem engineers that trap sediment and dampen waves has proven to be difficult, especially in the wave-exposed and eroding areas where they are needed the most. Environmental stressors, such as hydrodynamic stress and predation, can only be overcome if transplanted organisms are able to establish self-facilitating feedbacks. We investigate if the artificial lowering of multiple environmental stressors can be used to give transplanted juveniles the opportunity to form a self-sustainable system and thereby increase their long-term survival on wave-exposed and eroding shores. We designed a large field experiment using juvenile mussels (Mytilus edulis) as model species on a wave-exposed tidal flat in the Oosterschelde estuary (the Netherlands). We tested if the environmental stress caused by a high predation pressure and wave-driven dislodgement could be reduced by a combination of artificial structures such as fences (to exclude predatory crabs), attachment substrates (such as coir-net or oyster shells), and breakwaters. Despite a low overall mussel survival (29%), we found that under strong hydrodynamic conditions, experimental fences and attachment substrates increased the retention of transplanted mussel seed. However, modification of local hydrodynamic conditions using breakwaters did not improve mussel coverage preservation. Overall, this study highlights the potential of using techniques that lower multiple environmental stressors to create a window of opportunity for establishment in highly dynamic ecosystems.

“…Therefore, species distribution models have historically focused on abiotic factors to determine where organisms live (Graciá 2020, but see recent advances by Gargano Biotic interactions often result in aggregation, with a high potential impact on the distribution of populations and species. For example, individuals may be found in clusters in order to defend against biotic threats (Bertolini et al 2019) or aggregating around bene cial species whose suitable environmental conditions are patchily distributed (Drake & Richards 2018; Hochstrasser & Peters 2004). Furthermore, if an aggregated species serve as the resource for yet another species, the host distribution can shape the distribution and size of resource-dependent populations, modify the exploitative behaviour (Goulson 2010; Matter 2000) and in uence coexistence with other resource-dependent species (Chesson 2000;Lancaster & Downes 2004).…”

Context Biotic resource exploitation is a critical determinant of species’ distributions. However, it is difficult to quantify resource exploitation patterns through space and time, complicating their incorporation in spatial ecology studies. Therefore, understanding the local drivers of spatial patterns of resource exploitation may contribute to better large-scale species distribution models. Objectives We investigated (1) how the resource exploitation patterns of two trophic interactions (plant-insect) are explained by insect behaviour, resource aggregation, and potential insect-insect interactions. We also analyzed how (2) resource patch size and (3) resource accessibility in a heterogeneous landscape affected host exploitation patterns. Methods We quantified nectar robbing by insects in the genus Bombus (bumblebees) and frugivory by Brachypterolus vestitus larvae (Antirrhinum beetle) on Antirrhinum majus L. (wild snapdragons) in the Pyrenees Mountains, Catalonia, Spain. We tested hypotheses about resource exploitation by integrating spatial analyses at multiple scales. Results Both trophic interactions were aggregated, explained by the aggregation of their resource. At some scales, nectar robbing is more aggregated than the resource. Trophic interaction abundance is proportional to resource patch size, following the ideal free distribution model. Landscape features do not explain the locations exploited. Nectar robbing and frugivory occur together more often than expected. Conclusions Our findings suggest that multiple biotic and ecological spatial factors may simultaneously affect resource exploitation at a local scale. These findings should be considered when developing agricultural projects, management plans and conservation policies.

could potentially be a better donor source for intertidal transplantations, as young mussels may still possess a sufficiently high capacity for phenotypic plasticity, making them capable of acclimating to a new environment. This chapter focuses on the understanding of how mussels adjust to a new environment, and which environmental factors (e.g., exposure to the air and wave action) are driving these adjustments. This knowledge can prevent the transplantation of organisms with illadjusted phenotypes and ultimately increase the transplantation success. Chapter 3: Lowering environmental stressorsNewly transplanted mussels are highly vulnerable to dislodgement by hydrodynamic forces and to predation by crabs or shorebirds (Capelle et al., 2014). As a result, the establishment might require a "window of opportunity," defined as a specific disturbance-free period (Balke et al., 2011;Balke et al., 2013). Additional measures are often needed to artificially create such a window of opportunity on a highly dynamic coast, as the chances are very low for such moments to naturally occur at the same time and space as the restoration effort being executed. Engineering measures such as breakwaters or attachment substrates may be used to create a window of opportunity and kick-start establishment. In this chapter, we tested whether the environmental stress caused by a high predation pressure and wavedriven dislodgement could be reduced through a combination of artificial structures such as fences (to exclude predatory crabs), attachment substrates such as coir-net or oyster shells (to enhance attachment strength) and breakwaters (to reduce dragforces from waves). Overall, this study highlights the potential for using techniques that can lower multiple environmental stressors to create a window of opportunity for establishment in highly dynamic ecosystems. Chapter 4: Promoting self-facilitating feedback processesCoastal ecosystem engineers often depend on self-facilitating feedback processes to ameliorate environmental stress. This makes the restoration of such coastal ecosystem engineers difficult. On soft-bottom mudflats, mussels attach themselves to conspecifics and aggregate into distinctive patterns (van de Koppel et al., 2005a;Commito et al., 2014) to increase their resistance to dislodgement by hydrodynamic forces (Liu et al., 2014) and create a safety in numbers effect and reducing the chance of falling prey to predators (Cote & Jelnikar, 1999;Hunt & Scheibling, 2001). Recent studies emphasize the importance of integrating these kinds of positive intraspecific feedbacks to improve transplantation success (Silliman et al., 2015;Renzi et al., 2019;Valdez et al., 2020). However, large-scale and cost-effective restoration methods that consider positive feedback interactions, in addition to creating a window of opportunity for the establishment of target organisms, are still scarce.
