Marine litter is one of the main sources anthropogenic pollution in marine ecosystem, with plastic representing a global threat. This paper aims to assess spatial distribution macro-litter on seafloor, identifying accumulation hotspots at northern Mediterranean scale. Density indices (items km–2) from MEDITS trawl surveys (years 2013-2015) were modelled by generalized additive models using Delta-type approach and several covariates: latitude, longitude, depth, seafloor slope, surface...
The Mediterranean Sea is a large marine ecosystem with high heterogeneity in both environmental and ecological characteristics. It presents clear gradients from north to south west east. also an important area terms of biodiversity conservation vulnerable species, it suffers several cumulative human impacts, such as fishing climate change. Previous studies have characterized spatial temporal patterns species distributions indicators. However, comprehensive analysis combining wide...
Ecological resilience has become a conceptual cornerstone bridging ecological processes to conservation needs. Global change is increasingly associated with local changes in environmental conditions that can cause abrupt ecosystem reorganizations attending system-specific fluctuations time (i.e. dynamics). Here we assess dynamics climate-driven ecosystems transitions, expressed as the relevant contribution of species different life-history strategies, two benthopelagic systems. We analysed...
The arrival of a new invasive alga, Rugulopteryx okamurae, in the Strait Gibraltar (SoG) 2015 marked an unprecedented milestone North African and, later, European marine ecosystems. Nowadays, it is colonising vast infralittoral areas and significantly modifying some habitats associated communities southern Iberian Peninsula. In recent expeditions, high amount free drifted thalli this alga has been detected different circalittoral bathyal northern SoG Alboran Sea. present study combines...
The production of the aquaculture industry has increased to be equal that world fisheries in recent years. However, faces threats such as infectious diseases. Betanodaviruses induce a neurological disease affects fish species worldwide and is caused by nervous necrosis virus (NNV). NNV nude capsid protecting bipartite RNA genome consists molecules RNA1 RNA2. Four strains distributed are discriminated according sequence homology protein encoded Since its first description over 30 years ago,...
The high species richness, coupled with proportion of endemism, makes the Mediterranean one world’s ‘biodiversity hotspots’. However, continuous increase in fisheries last few decades has led to overexploitation their main commercial stocks. Using fishery-independent data collected under framework MEDITS trawl surveys carried out over 20 years, we study demersal fish diversity pattern at a large spatial and temporal scale determine whether it is being affected by general fishing resources....
Molluscan assemblages of circalittoral and bathyal soft bottoms the northern Alboran Sea were studied using an experimental otter trawl. Samples fauna collected from 190 hauls during four MEDITS surveys carried out in spring between 2012 2015 at depths ranging 30 to 800 m. Measurements water column variables (temperature salinity) sediment samples taken same locations where faunistic sampling was out. A total 101 species grouped 55 families recorded. Cephalopods most abundant group, with...
This study describes the four main demersal fish assemblages identified along continental shelf and slope (30–800 m depth) of northern Alboran Sea (western Mediterranean), based on analysis MEDITS (International bottom trawl survey in Mediterranean) 12-year data series. We collected 186 species belonging to three classes, 24 orders 69 families. Taxonomically, order Perciformes was most diverse, represented by 18 families 58 species. Each assemblage had particular characteristics abundance,...
The uncertainty in age estimation by otolith reading may be at the root of large variability red mullet (Mullus barbatus) growth models Mediterranean. In MEDITS survey, data are produced following same sampling protocol and methodology. However, ageing is assigned using different interpretation schemes, including variations theoretical birthdate number false rings considered, addition to differences experience level readers. present work analysed influence these geographical location on a...
The composition and structure of molluscan assemblages inhabiting circalittoral upper middle slope soft bottoms along the northern Alboran Sea, including Ridge, was studied in relation to sediment characteristics water bottom variables. Samples were collected using a beam-trawl (50 sampling stations) during 2014, 2015 2016 MEDITS expeditions. A total 29 464 individuals 215 taxa six different classes have been found, with gastropods bivalves representing most diverse abundant ones. It is...
Abstract Since the 1990s, most currently assessed Mediterranean nekto‐benthic stocks have been exploited above maximum sustainable yield and declined. This study explores co‐occurrence of essential fish habitats for important resources by bottom‐trawl fisheries in western areas importance communities. Fishery‐independent data obtained from scientific surveys were used to identify persistent hotspots recruitment species around Iberian Peninsula Balearic Islands between 2002 2016, as an...
The large-scale distribution pattern of megafauna communities along the Mediterranean middle slope was explored. study conducted between 500 and 800 m depth where deep-water fishery occurs. Although community studies carried out deeper than are partly available for some geographic areas, few comparative have been out. Within framework MEDITS survey programme, we compared structure in ten geographical sub-areas (GSAs) coasts. Additionally, spatial fishing analysed using vessel monitoring by...
Protogrammus alboranensis n. sp. is described on the basis of four specimens from Alboran Sea, western Mediterranean Sea. It characterized within genus by a total nine unbranched rays second dorsal fin, eight anal very small preopercular spine with an upcurved main tip and one point margin, which lacking antrorse at base, first spines fin filamentous much longer than ray in males, last reaching beyond caudal base distally black males (translucent females). A key to species presented;...
Trawling pressure and environmental changes may affect the composition of fish assemblages. Our knowledge on large spatio-temporal patterns demersal remains incomplete for Mediterranean Sea. We investigated (1) stability assemblages, (2) relationships between these assemblages potential structuring factors (trawling conditions) in order to assess dynamic assemblage structure at scale northern analysed a dataset 18062 hauls from 10 800 m depth performed annually during last two decades across...
Information on the distribution of small benthic fish such as gobies is sometimes scattered or incomplete. This probably due to sampling difficulties involved in study these fishes at depths below those accessible for SCUBA diving techniques. These are cases Buenia massutii Kovačić, Ordines et Schliewen, 2017 (recently described and currently only known from Balearic Islands (western Mediterranean), locality where it was described); Vanneaugobius dollfusi Brownell, 1978 (only...
The Gulf of Cadiz (GoC) in the Atlantic Ocean and Alboran Sea (AS) Mediterranean are part an oceanographic complex system extreme importance exchange waters between through Strait Gibraltar. Besides its significant role as ecological transition system, it is unknown whether regional local environmental drivers affect similarly species inhabiting these two adjacent connected ecosystems. This study analyses spatial shifts representative demersal their response to demographic regions using...
The present study describes for the first time spatial distribution of five macrourid species throughout Mediterranean Sea and analyses depth, geographical time-related trends regarding their abundance, biomass mean fish weight. data were collected as part MEDITS annual bottom trawl survey carried out by several European countries from 1994 to 2015, using same standardized gear sampling protocol. most represented in terms abundance was Coelorinchus caelorhincus. bathymetric trend different...
This study analyses the samples collected annually (2012 to 2018) on circalittoral and bathyal soft bottoms (30 800 m) by MEDITS surveys in northern Alboran Sea (including Island) Gulf of Vera determine composition, structure distribution decapod crustacean assemblages. A total 94 species were identified. Non-metric multidimensional scaling showed depth be main factor for distinguishing four assemblages: inner shelf (30-100 m depth), outer (101-200 m), upper slope (201-500 middle (501-800...
