Concrete is extensively used in coastal engineering and development which, addition to its high carbon footprint, threatens intertidal habitats ecosystems. Eco-engineering addresses this by designing habitat features into infrastructure. The chemical bioreceptivity of cement has been shown vary, but ordinary Portland generally considered be the least bioreceptive. In study, we compare two low mortars (a natural, single source (VP), an cement/ ground granulated blast furnace slag blend (GGBS)) with cement-based control mix (OPC). three were made smooth blocks which secured crates deployed subtidally estuary sites on south UK coast for 1 year. At 3-, 6- 12-months intervals a crate was recovered from each site species abundance, biomass assemblage composition determined. After 12 months, VP mortar significantly more rich than both OPC GGBS mortar, organisms abundant (numeric counts only), though varied site. However, controls showed higher percentage cover biota mixes harbours. Overall, all mortars. It evident that primary OPC, inconsistent between ecological metrics study using lower cements does not necessarily enhance colonisation. these may therefore perform inconsistently other intrinsic factors impact succession, such as rugosity, should prioritised when enhancements. Sustainability materials, opting cements, also priority.

Transitional waters are important habitats both for biodiversity and ecological functions, providing valuable natural resources relevant ecosystem services. However, they highly susceptible to climate changes anthropogenic pressures responsible losses require specific biomonitoring programs. Benthic macroinvertebrates suitable as indicators of transitional waters, being affected by biological, chemical, physical conditions the ecosystems about their life cycles space-use behaviour. The advent high-throughput sequencing technologies has allowed investigations, at molecular level, in multiple different guilds. macroinvertebrate communities' composition been investigated, mainly through DNA extracted from sediments marine riverine ecosystems. In this work, benthic communities explored eDNA metabarcoding water samples a Mediterranean ecosystem. This research highlighted validity an efficient tool assessment community structure unveiling spatial heterogeneity correlated measured environmental gradients. results suggest that peculiar features ecosystems, such shallow limited currents, facilitate analysis surface samples, opening more rapid accurate monitoring programs these
