Hanke, Andra Oros, Andreja Ramšak, Oliver Bajt, 2015, final research report Abstract: This report represents the result of the scientific and technical review of Commission Decision 2010/477/EU in relation to Descriptor 8. The review has been carried out by the EC JRC together with experts nominated by EU Member States, and has considered contributions from the GES Working Group in accordance with the roadmap set out in the MSFD implementation strategy (agreed on at the 11th CIS MSCG meeting). The report is one of a series of reports (review manuals) including Descriptor 1, 2, 5, 7, 8, 9, 10 that conclude phase 1 of the review process and, as agreed within the MSFD Common Implementation Strategy, are the basis for review phase 2, towards an eventual revision of the Commission Decision 2010/477/EU. The report presents the state of the technical discussions as of 30 April 2015 (document version 8.0: ComDecRev_D8_V8), as some discussions are ongoing, it does not contain agreed conclusions on all issues. The views expressed in the document do not necessarily represent the views of the European Commission.

343. Grapevine flavescence dorée (FD) follow up Vitisens, GRAFDEPI and Qdetect (GRAFDEPI2) : final reportMarina Dermastia, Helga Reisenzein, Luca Ferretti, 2015, final research report Abstract: Europe is the world’s main producer and exporter of grapevine planting material and wine. This important economic sector is facing epidemic threats of at least 10 grapevine yellows diseases (GY) caused by phytoplasmas. In Europe the main phytoplasmas associated with GY are ‘Candidatus’ phytoplasma solani’ (BNp), which is a causal agent of bois noir and FDp, which causes flavescence dorée. Phytoplasmas are notoriously difficult to detect and identify and their specific detection relies exclusively on the molecular methods. Recently new methods, which are reliable, sensitive, fast, less expensive and suitable for using onsites, have been introduced. Among them is a loop-mediated isothermal amplification (LAMP) method, with several advantages (e.g. low sensitivity to plant extracts inhibitors, speed, robustness, simplicity of use) over the other methods (e.g. the real-time PCR). In a recently finished FP7 project VITISENS, a new LAMP protocols have been developed for specific detection of FDp, however, they have not been tested in the interlaboratories trials. In addition, there is no validated LAMP protocol available for the specific detection of BNp at the moment.
The main objectives of this project were:
(1) Development of new loop-mediated isothermal amplification (LAMP) based protocols for accurate, reliable, fast and affordable diagnostics of ‘Candidatus Phytoplasma solani’ (BNp), which will be applicable in-field
(2) To study new possible hosts plants and insect vectors of phytoplasma FDp.
(3) To organize an interlaboratory test performance study (TPS) to obtain validation parameters for the selected LAMP protocols for BNp, as well as for the LAMP assay for FDp detection developed in the course of the FP7 project VITISENS.
Keywords: phytoplasmas, grapevine yellows diseases, LAMP, real-time PCR

346. Assessment of coastal pressures in the MSFD sub-regions of the SES : PERSEUS projectJean-François Cadiou, Anik BrindʹAmour, Alenka Malej, Andra Oros, 2015, final research report Abstract: The analysis of historical data sets and the results obtained from field studies about the pressures exerted on coastal ecosystems in 18 sites of the Mediterranean and the Black Sea showed that :
Inputs form Po and Danube rivers showed a high interannual variability. After an increase of eutrophication over the 70-80s, a decrease of nutrients inputs, especially of phosphate, was recorded since 1990. Positive impacts are seen on phytoplancton communities.
In the vicinity of most coastal big cities the policy measures taken in order to reduce polluted water discharges show their effectiveness although some local issues still exist.
Chemical contaminants levels decrease rapidly when the distance increase from point sources. However a large amount of coastal inputs is exported offshore. Attention should be paid to the fate and the impact of new emerging pollutants. At the basin scale, contaminant concentrations in biota show very different patterns depending on substances. For some substances, the biogeochemical background and the environmental conditions play a important role in the contamination of marine organisms.
There is globally no evidence of neither degradation nor clear trends regarding seagrass meadows. The status of seagrass habitats is correlated to water quality. It can be concluded that human pressures have not affected seagrass meadows in a irreversible way. Seagrass habitats can recover (slowly) when pressures decrease.
The rate of new introductions of Non Indigenous Species has been increasing at all coastal study areas after 2000. An increase of the Lessepsian species migration is seen, in link with climate change
The analysis of 18 years of data about demersal fish communities showed a geographic variability in functional group (FG) biomass trends. Nearly half of the studied Mediterranean areas shows an increase of FG biomass. Changes respond mainly to nutrient inputs trends and to a lesser extent fishing pressure.
Marine litter is increasing pressure on marine ecosystems. The majority of items were made of plastic often exceeding the global average of 75%. Some harmful effects on fauna are documented (birds, turtles…) but impact is poorly known.
The lack of standardized methods for underwater noise measurements make difficult to assess the level of the pressure and the impact on marine ecosystems.

348. Metabolic rates of groundwater species as a function of body mass and temperatureTiziana Di Lorenzo, Nataša Mori, Tatjana Simčič, 2024, review article Abstract: Research on the metabolic physiology of groundwater species, particularly regarding oxygen consumption
rates (OCR), has made significant advancement, revealing valuable insights into the adaptations of exclusively
groundwater-dwelling (stygobitic) species. However, a comprehensive understanding of how these metabolic
rates scale with body mass and respond to temperature changes remains elusive. This study aims to bridge this
gap by reviewing published data on OCR across a variety of groundwater organisms to elucidate patterns of
metabolic rates in relation to body size and temperature. We employed a combination of literature review and
quantitative analyses, focusing on the allometric scaling of OCR with body weight and the effect of temperature on metabolic rates. Our findings indicate that OCR scales with body weight in an allometric pattern,
with an inter-species slope of 0.80, suggesting non-isometric scaling. Furthermore, our analysis showed that
stygobitic species’ metabolic rates are less responsive to warming than those of non-stygobitic species at low to
moderate temperatures. However, at higher temperatures, metabolic rates in stygobitic species decline faster
than in non-stygobitic taxa, highlighting a potential vulnerability to global climate change. This study contributes to our understanding of the metabolic strategies of groundwater species, underscoring the need for further
research to fully grasp the eco-evolutionary implications of these findings for groundwater conservation.

350. Morfološka variabilnost črnike (Quercus ilex L.) v SlovenijiMartin Jež, Robert Brus, Kristjan Jarni, 2024, original scientific article Abstract: V članku je predstavljena črnika (Quercus ilex L.), ena glavnih drevesnih vrst evmediteranske flore na območju Slovenije, kjer raste na razpršenih nahajališčih na severni meji svojega naravnega areala. Glavni namen raziskave je bil preučiti morfološko variabilnost njenih listov. V raziskavo je bilo vključenih sedem naravnih populacij črnike v Sloveniji. Morfometrijska analiza je pokazala veliko variabilnost listov in značilne razlike med populacijami, ki smo jih potrdili pri skoraj vseh preučevanih morfoloških znakih. Na podlagi ugotovljenih morfoloških razlik lahko slovenske populacije razdelimo v tri geografskomorfološke skupine: i) populacije na Goriškem (Sabotin, Sv. Gora in Lijak), ii) Nanos - Osp in iii) populaciji v dolini reke Dragonje. Morfološka variabilnost kot odsev genetske variabilnosti je posledica prilagoditve na lokalne okoljske razmere. Črnika v Sloveniji za zdaj ni ogrožena vrsta, vendar bi bilo pri morebitnih aktivnih varstvenih ukrepih za njeno ohranjanje smiselno čimbolj upoštevati ugotovljene tri geografsko-morfološke skupine.
