Abstract

Information on the distribution, population traits and conservation status of the endangered coral Cladocora caespitosa is still missing for most of its distribution area. As prompted throughout conservation assessments and red lists, obtaining such information is a priority in the current context of generalized decline of benthic communities in the Mediterranean Sea. We assessed these topics in the main C. caespitosa populations (n = 18) thriving throughout UNESCO's Menorca Biosphere Reserve (MBR), which includes the largest marine Biosphere Reserve in the Mediterranean Sea. The MBR harbours an arrange of C. caespitosa populations of great interest, with a good representation of the contrasted environmental conditions that this long-lived coral is able to thrive in. Although average coral cover falls into the lower range compared to other Mediterranean populations, it is the ubiquity of the species along Menorca's coastline that differentiates this location from others described to date. Warming-related mortality can be considered the main threat to this species in the MBR, showing an average colony necrosis of ∼30%. Nevertheless, special attention should also be paid to other potential threats derived from human activity, such as pollution and coastal development. This study should be used as a baseline to implement conservation and management actions in the MBR, including a long-term monitoring programme.

Abstract

Research in marine Spanish waters are focused on several actions to achieve an effectively management on protected areas, with the active participation of the stakeholders and research as basic tools for decision-making. Among these actions, there is one about the knowledge and control on NIS. One of its objectives is the creation of NIS factsheets, which are going to be added to the National Marine Biodiversity Geographical System (GIS) providing complementary information about taxonomic classification, common names, taxonomic synonyms, species illustrations, identification morphological characters, habitat in the native and introduced regions, biological and ecological traits, GenBank DNA sequences, world distribution, first record and evolution in the introduced areas, likely pathways of introduction, effects in the habitats and interaction with native species, and potential management measures to apply. The database will also provide data for (1) the European online platforms, (2) the environmental assessment for the Descriptor 2 (D2-NIS) of the EU Marine Strategy Framework Directive (MSFD), as well as (3) supporting decisions made by stakeholders. It is the result of extensive collaboration among scientist, manager’s and citizen science in the Spanish North-Atlantic, South-Atlantic, Gibraltar Strait-Alboran, Levantine-Balearic and Canary Islands marine divisions, providing an updated overview of the spatial distribution of relevant extended and invasive NIS of recent and established NIS introduced by maritime transport and aquaculture pathways, as well as on cryptogenic or native species in expansion due to the climatic water warming trend.

Censos visuales con escafandra autónoma, en arrecifes artificiales y en roca natural, en los que se cuentan y miden los ejemplares de langosta asentados. Se han fondeado 36 colectores artificiales a 25 m de profundidad, en tres zonas: Favàritx, La Mola e Illa de l’Aire. Los colectores constan de una base de hormigón, de un peso de 50 kg, sobre la que se fijan 3 pisos de 4 ladrillos cada uno. Los censos en roca natural se llevan a cabo en dos zonas: Cap de Cavalleria e Illa de l’Aire.

Abstract

We report on the presence of the pearl oyster Pinctada imbricata radiata (Leach, 1814) in two sheltered areas of the island of Minorca, Maó Harbour and Fornells Bay. Shallow depths (0-1.5 m) have been surveyed by free diving. Living oysters have been found in only 4 of the 22 surveyed sites, with densities ranging between 2.12 oysters·100 m-2 and 0.12 oysters·100 m-2, which indicates that the species is currently non-invasive. Average shell length in the observed specimens was 60.2 ± 13.9 mm (mean ± SD). According to the size of the oldest specimen found and the reports of a shellfish farmer from the Maó Harbour, date of introduction should be around year 2016. Since the introduction is recent, attention must be paid to the future spread of this species, regarding its high invasive capacity in several Eastern Mediterranean localities.

Abstract

Species distribution models (SDMs) have been used to predict potential distributions of habitats and to model the effects of environmental changes. Despite their usefulness, currently there is no standardized sampling strategy that provides suitable and sufficiently representative predictive models for littoral marine benthic habitats. Here we aim to establish the best performing and most cost-effective sample design to predict the distribution of littoral habitats in unexplored areas. We also study how environmental variability, sample size, and habitat prevalence may influence the accuracy and performance of spatial predictions. For first time, a large database of littoral habitats (16,098 points over 562,895 km of coastline) is used to build up, evaluate, and validate logistic predictive models according to a variety of sampling strategies. A regularly interspaced strategy with a sample of 20% of the coastline provided the best compromise between usefulness (in terms of sampling cost and effort) and accuracy. However, model performance was strongly depen upon habitat characteristics. The proposed sampling strategy may help to predict the presence or absence of target species or habitats thus improving extensive cartographies, detect high biodiversity areas, and, lastly, develop (the best) environmental management plans, especially in littoral environments.
