Article
Ecological restoration is an important tool to reverse habitat loss and recover ecosystem services. Here, for two years, we examine the dynamic of Posidonia oceanica following the restoration of a 1149 m² meadow damaged by the Concordia shipwreck. To evaluate the suitability of a recently employed seagrass restoration protocol, we assessed the patc...

The need for habitat recovery in coastal areas, especially those subjected to intensive exploitation, has increased because of significant historical loss and alteration of habitats and, therefore, adverse ecological impacts. The present study defines a stepwise approach to mitigate habitat loss in deep coastal environments, describing the planning...
Data
MedFever – An expanding network of 12 small observatories was established in the Tyrrhenian Sea in 2021 by MedSharks and ENEA, building on the experience of an observation point established in 2016 in the Gulf of Naples. Very high frequency measurements (15 minutes) at some standard depths (5-15-35m; occasionally at 10-20-25-30-50-60m) were obtaine...

Seagrasses rank among the most productive yet highly threatened ecosystems on Earth. Loss of seagrass habitat because of anthropogenic disturbances and evidence of their limited resilience have provided the impetus for investigating and monitoring habitat restoration through transplantation programmes. Although Structure from Motion (SfM) photogram...
Article
Protection and restoration are crucial components of conservation strategies aimed at preserving biodiversity and ecosystem services. Here, we propose a successful protocol to restore the most important and protected Mediterranean seagrass species, Posidonia oceanica. A 52-month experiment was carried out to evaluate the feasibility of the restorat...

These datasets derived from our mapping protocol are presented as a research article in the Journal of Environmental Management [1]. In particular, by using a Structure from Motion photogrammetric workflow we produced high spatial resolution 2D raster maps and 3D outputs such as dense points clouds and textured meshes of an underwater seagrass rest...

Coralligenous reefs are characterized by large bathymetric and spatial distribution, as well as heterogeneity; in shallow environments, they develop mainly on vertical and sub-vertical rocky walls. Mainly diver-based techniques are carried out to gain detailed information on such habitats. Here, we propose a non-destructive and multi-purpose photo...

The role of habitat degradation on the spread of the alien green alga Caulerpa cylindracea is reported here by comparing observations achieved through a multi-year assessment on three Mediterraneans habitats, namely Posidonia oceanica meadows, Phyllophora crispa turf, and coralligenous reefs. Due to the peculiarity of the study site, both natural-r...

The picture shows a dead matte area, precisely when the Costa Concordia shipwreck occurred, characterized by the spread of the invasive green algae Caulerpa cylindracea. The matte is a biogenic substrate, formed by the dense twist of seagrass roots, rhizomes, and sediment, that represents what remains after the regression of the Mediterranean endem...

The assessment of effective and affordable restoration interventions is pivotal to developing new tools to mitigate habitat loss and enhance natural recovery. Gorgonians create important three-dimensional habitats in the Mediterranean Sea providing several ecosystem services associated with coralligenous reefs. Transplantations of the octocorals Eu...
Article
We report here for the first time the effectiveness of Reteporella bryozoan genus in the early stage of coralligenous reefs recolonization through the analysis of the settlement and the population size structure over a two-years period at two impacted and two control sites. Results highlighted how Reteporella spp. colonies strongly recolonized, fro...
Article
Coralligenous reefs are considered as one of the most important benthic ecosystems in the Mediterranean Sea in terms of biodiversity, ecosystem functioning, and aesthetic value. Bryozoans deserve special attention within the coralligenous framework fauna: they are among the most common animals, showing high diversity values and playing different fu...
Article
The Costa Concordia shipwreck permitted to assess how multiple disturbances affected marine biota at different spatial and temporal scales, evaluating the effects of mechanical and physical disturbances on Posidonia oceanica (L.) Delile, an endemic seagrass species of the Mediterranean Sea. To assess the impacts of the shipwreck and its salvaging f...

The effects of unusual very high waves (>5 m) for Tyrrhenian Sea, due to the major storm of 30th October 2018 were assessed along a rocky coast of Giglio Island through UAV-based photogrammetry coupled with low cost RTK-GPS survey. These tools demonstrate how sub-decimeter GIS drone-derived data can become a reliable tool for accurate coastal monit...

Project
An expanding network of small observatories was established in the Tyrrhenian Sea in 2021 by MedSharks and ENEA, building on the experience of an observation point established in 2016 in the Gulf of Naples. Leveraging the engagement of civil society will increase the monitoring capabilities across the basin and contribute to a better understanding of the stresses acting on coastal ecosystems. Very high frequency measurements (15 minutes) at some standard depths (5-15-35m; occasionally at 10-20-25-30-50-60m) are obtained by voluntary diving centers using calibrated HOBO sensors (after calibration accuracy is about ±0.1 °C). So far, the network consists of 12 stations evenly covering the Tyrrhenian sea.
