MSc Thesis. Universiteit Gent: Gent. 89, vol 2 (foto's, figuren, platen) pp.
Field exclusion experiment: a randomized block design was used, consisting of nine experimental units. Three replicates were taken for each treatment (Cage, Partial cage and Blanco respectively). In the Cage, the epifauna was excluded; in the Partial cage (the first control introduced in our experiment), the epifauna was not excluded, so only the influence of the cage itself was investigated; in the Blanco (the second control in our experimental design, without cage) the epifauna remained well in order to follow the natural changes in time of the meiobenthos in the Avicennia marina mangal. Three monthly meiobenthic samples were collected for each treatment; together with those meiobenthic samples, abiotic factors (grain size analysis, curtosis, skewness, median particle diameter, porosity, % organic material, temperature, redox potential, pigment analysis (measurements of chlorophyl a, fucoxanthin), nutrient analysis (NQ,- NO3, NH4+, and Si), salinity, pH and dissolved oxygen) were measured once a month.

Furthermore this dataset also contains additional information to calculate Biomass and Abundance: V1_L, V2_ml, V3_ml, Koefficient, N_count and V_um3. V1_L is the volume of the water sample taken in liters. V2_ml is the volume of the filtered sample in milliliters (V1 after filtration). V3_ml is the volume (in milliliters) of one drop taken from the V2 sample to be examined under the microscope. Koefficient is a multiplying factor calculated from V1, V2 and V3. N_count is the number of individuals that was observed under the microscope for 1 species. V_um3 is the average volume of one individual in cubic micrometers.

Abundance = N_count*Koefficient Biomass = N_count*Koefficient *V_um3*10^-3
The fishery Ground near Alexandria. XX. Nemertini by Herman Friedrich (1940). Notes and Memoirs No 38.

This is a historical dataset that was published in 1940 by Herman Friedrich and concerns the collection of 9 tubes of Nemerteans collected during the floristical and faunistical survey of Adolf Steuer on the coasts near Alexandria mainly with the vessel “El Hoot”. This dataset covers the time span of 6/9/1933 to 12/11/1933.The material was unsatisfactory so they identified to the order level. The digitization of this dataset was done by LifewatchGreece team.
Collection Cnidaria SMF

The Cnidaria collection is part of the SeSAM collections of Senckenberg which combines all collections held at the Senckenberg Natutal History Museum of Frankfurt. This collection contains Cnidaria from all over the world.
Within the Cnidaria collection approximately 100 primary type species are present; the type and reference material originates mainly from the works of  Schultze (1896 - 1903), Vanhöffen (1902), Kükenthal (1911), Stechow - Müller (1913),  Stechow (1923), and Graßhoff (u.a. 1977, 1982, 1986, 1988, 1992,  1999, 2000).
Collection Bryozoa SMF

The Bryozoa collection is part of the SeSAM collections of Senckenberg which combines all collections held at the Senckenberg Natutal History Museum of Frankfurt. This collection contains Bryozoa from all over the world.
The Section Marine invertebrates 3 of the Senckenberg Research Institute houses a wide-ranging collection of bryozoans from the North Sea, the Mediterranean, the Arabian seas. the East Asian coastal seas (Philippines, Japan, Hainan/China), the Southern Ocean (New Zealand, Australia), and Antarctica. The collection has been significantly expanded by the donation of about 15,000 specimen boxes of Professor Heinrich Ristedt (Bonn, Germany). 

The Ristedt -Collection is composed of dried specimens, mounted on match boxes in small plastik containers. We have adopted this practical system to integrate all new collections.

The Section´s collection of fossil bryozoans is even larger, since Professor Voigt (1905-2004) has left us with a massive legacy of the wordwide  most comprehensive collection of Cretaceous bryozoans.  He was one of the greatest ever bryozoologists, a scientist with an 80 year long record of bryozoan publications. His enormous bryozoan collection occupies thousands of cavity slides, and boxes.  Although most of the specimens represent the Upper Cretaceous of Northern Europe, there are significant collections from other stratigraphical periods such as the Ordovician (Caradoc) kuckersite (oilshale) deposits from Estonia. 

Aside from the Voigt legacy, individual benefactions have likewise expanded the variety of fossil bryozoans in our collecton, including Cretaceous bryozoans donated by Ursula Schneemilch (Hannover), and Upper Paleozoic bryozoans, some of them types, given to us by Dr. Andrej Ernst (Kiel).

TARTACare Calabria: monitoring and conservation of the loggerhead turtle nesting activity along the Ionian coast of Calabria (Southern Italy) (aggregated per 1-degree cell)

Post-nesting satellite tracking of two loggerhead turtles in the southern Ionian coast of Calabria, Italy.
The Southern Ionian coast of Calabria is currently recognized as the main nesting ground for loggerhead turtles in Italy, accounting for 70% of the total nesting events which were documented nationwide over the last six years (2003-2008). This finding arose from a research project (TARTACare Calabria) initiated by the Dept. of Ecology of Calabria University (Rende, Italy) in summer 2000. This project mainly aims at nest monitoring and protecting, but also has additional objectives such as estimating of nesting population, genetic analysis, beach characterization, definition of type and entity of threats to nesting derived from human impact (including fishing impact). Satellite tracking of nesting females has also been attempted to track the post-nesting migrations and to ultimately identify the so far unknown foraging areas of the turtles nesting on the Ionian coast. Zeffiria and Esperia are the first two turtles nesting in Italy that are being tracked by satellite during their post-nesting migrations. Data providerIslameta Group, Dept. of Biology - University of PisaOriginating data centerSatellite Tracking and Analysis Tool (STAT)Project partnerThe overall TARTAcare project of the Dept. of Ecology, Calabria University is a collaboration with: Islameta Group, University of Pisa (satellite tracking), University of Rome Tor Vergata (genetic analysis), University of Florence (beach characterization), Stazione Zoologica A.

Nematode biodiversity data from the North Sea Benthos Survey

All nematode data from the North Sea Benthos Survey (NSBS) were compiled in a smaller dataset.
The NSBS was carried out in 1986 as an activity of the Benthos Ecology Working Group of ICES. Benthic samples were taken in a standardised way, on a regular grid covering the whole of the North Sea, and analysed by scientists from 10 laboratories. Extensive work was done to standardise taxonomy and identifications across the different laboratories. A total of just over 1 000 species were reported from 235 stations. Most research however was focused on macrobenthos, while only limited research was done for meiobenthos.
Zooplankton of Lebanon

This dataset contains data of zooplakton species which were found in Lebanese waters. The study area extends over 150 km between the south of Lebanon and offshore Tripoli city in the North. Monthly, seasonally and annual cruises were carried out between 1965 and 2007. Surface and vertical plankton samples were taken at standard depths 0m, 0-25m, 0-100m, 0-200m.
Data are available as a classification of the frequency of occurance.
The Levantine Basin of the Eastern Mediterranean, including Lebanese seawaters fall in the warm temperate zone. This marine area is characterized with a heavy ologrtrophic water body and high temperature and salinity. The surface temperature averages vary from 17 °C in February and  a maximum of 30°C  in August, whereas the offshore surface salinity displays little fluctuations between 39.25 in April  and 39.75 in September. These values of T/S are the highest in the whole Mediterranean. Despite of these extreme hydrological conditions, the Lebanese seawater  show a highly diversified plankton community contrasting with poor plankton biomass.  	Most of the Mediterranean zooplankton groups are present in the area from the Protozoans up to Protochordates and Fish larvae. The zooplakton constitutes the  secondary producer of  organic substance, the phytoplankton being the primary producer. The zooplankton community, as that of the Levantine Basin present a high biodiversitry  with low  biomass and showing  pronounced  seasonal variations  in quality and quantity of the zooplankton. The maximum development of zooplankton is observed  in May June, just following the spring phytoplankton bloom. In winter, zooplankton is poor in quantity  but  very diversified corresponding with the mixing  and turn over of water layers leading to the vertical homothermal conditions. During summer, the stratification of the water masses in the layer 35-75 m creating the thermocline may lead to the impoverishment of zooplankton  in quantity and  quality. The majority of zooplankton organisms  display short biological  life cycle and some of them showing more than one annual generation. Several species that migrated through the Suez Canal, or invaded the Lebanese waters are of Indo-Pacific and/or Erithrean origin, called Lessepsians. Many of them  have established permanent populations competing with local and native  species. 
Many zooplankton species display vertical migrations due to hydrologic, physiologic  and trophic factors.Usually the herbivorous zooplankton stay in the euphotic zone (100-0 m ) rich in phytoplankton, whereas the carnivorous species live in the deeper seawater. However the diurnal vertical migration practiced by many species  has a physiological  and ecological reasons, namely the action of the light, the nutrition and reproduction.
	Generally, the LevantineBasin, including the Lebanese seawater is a zone show low primary productivity rate , inducing  poor zooplankton  and thus little  fisheries rentability.
Зоопланктон в прибрежных водах острова Змеиный в Черном море (2003-2006 гг.)

Species composition, abundance and biomass of zooplankton in the coastal waters of the Zmiinyi Island in the Black Sea in 2003-2006.
Odessa National I.I. Mechnikov University zooplankton datasets collected in the Zmiinyi Island coastal waters in the Black Sea in the framework of national research projects funded by the Ministry of Science and Education of Ukraine in 2003-2006. These datasets include about 1000 records with abundance and biomass for over 70 zooplankton species in 139 samples. Zooplankton sampling was performed using modified Apstein net with mesh size = 53 mkm.
Phytoplankton abundance and biomass data from 2007 to 2016 in the Bulgarian Black Sea

Phytoplankton data, species composition, abundance (cells/l) (SDN:P01: PU00M00Z) and biomass (mg/m3) (SDN:P01: WWBMM00Z) collected at coastal stations located in the 1n.m. Bulgarian Black Sea area and stations on  a coastal-open sea transect in the Bulgarian Black Sea region, including the EEZ, within EC,  FP7 Project SESAME.
Phytoplankton samples were collected by CTD probe (SBE-911)  with attached Niskin bottles at discrete depths, defined according to the in situ  fluorimeter readings (0m - thermocline- deep chlorophyll a maximum), and   1m above the bottom or down to 75 m depth at the deeper stations.   Phytoplankton samples (1000 ml water sample) were fixed on board in 4% formaldehyde solution, buffered to pH 8-8.2 with disodiumtetraborate. In the laboratory the samples are concentrated down to 50 cm3 by slow decantation after storage for at least 20 days in a cool and dark place. Taxonomic identification and cell counts are done under inverted microscope (Nikon T300E) connected to a video-interactive image analysis system ((L.U.C.I.A, Version 4.8, Laboratory Imaging Ltd, Prague) at 400x magnification by the Uteröhl (1958) method in Sedgwick-Rafter counting chambers. 400 cells are counted from each sample, while rare and large species are checked in the whole counting chamber (Moncheva and Parr, 2005/2015). The individual cell biovolume (V, μm3) is derived through the approximation of the cell shape of each species to the most similar regular solid, calculated by the respective formulas (Edier , 1979 ; Vadrucci et al., 2007),  averaged over measurement of ten cells from each species. Cell bio-volume is converted to weight (W, ng) following Hatchinson (1967). Taxonomic nomenclature is according to the on-line data-base of World Register of Marine Species (WoRMS) http://www.marinespecies.org/ and the Black Sea phytoplankton check-list. The QC/QA of the data is performed following the quality control Guidelines for phytoplankton (Moncheva, 2010).
