Hyytiälä SMEAR II site characteristics

Data of biomass, and soil sediment (organic matter, pH, temperature and particle size [< 63, < 125, < 250, > 250 and < 1000 µm]), for three diferent sites of Ria de Aveiro associated to two plant species: Juncus maritimus and Spartina maritima. Period of field survey has been bimestral in the year 2012

Biomass data (g fw m-2) of macrophytes collected in 5 stations in the Mar Piccolo in the period spring 2011-winter 2019. Presence of species is indicated by 0,01 value This data set includes biomass values of phytobenthic species, mainly seaweeds, recorded in the Mar Piccolo of Taranto in the years 2011-2019. Seasonal collection campaigns have been carried out in four stations and three replicates were collected for each station. Starting from 2016 a fifth station was analyzed (40°30'03.15"N; 17°18'30.99"E) . For station 1-4 location see (Petrocelli A., Cecere E., Rubino F. 2019. Successions of phytobenthos species in a Mediterranean transitional water system: the importance of long term observations. Nature Conservation 34: 217-246).

Biomass data (g fw m-2) of macrophytes collected in four stations in the Mar Piccolo in the period October 2007-September 2008. Presence of species is indicated by 0,01 value In the period October 2007-September 2008, a sampling campaign was carried out in the Mar Piccolo of Taranto, to assess the biodiversity of macrophyte populations. Four coastal stations were monthly monitored, two in the First Inlet (A 40°29'30.50"N 17°14'08.29"E) (B 40°30'03.86"N 17°15'20.52"E) and two in the Second Inlet (C 40°29'38.99"N 17°19'22.87"E) (D 40°28'22.17"N 17°18'35.79"E). A total of 79 taxa were recorded: 18 Chlorophyta, 5 Ochrophyta, 54 Rhodophyta, 2 Tracheophyta. 4 species were non-indigenous (NIS). The Tracheophyta Ruppia cirrhosa was recorded for the first time in the basin.

Long-term studies allow to evaluate all the significant changes which an ecosystem encounters with time. In this respect, the Mar Piccolo of Taranto represents a good example for the studies on the phytobenthos. Indeed: in the Twenties the first researches were carried out; up to the Seventies they were occasionally performed; in the Eighties they became continuous and are still ongoing as such. Therefore, the presence of historical series of data gives the chance of assessing both qualitative and quantitative modifications, which occurred against the phytobenthic communities of the basin. Irma Pierpaoli was the first phycologist in Taranto. She was a young teacher of Natural Sciences from Ancona, who taught in Taranto in a secondary school from 1920 to 1925, dabbling in picking seaweeds along the Mar Piccolo shore before going to school in the morning. Of this activity, she left two published papers and an herbarium. Up to the second half of the Eighties’, no phycological information are available on the Mar Piccolo. But, in 1986, the Phycological Laboratory was set up at the Istituto Talassografico, now CNR-IRSA, and the orderly study of the Mar Piccolo phytobenthos began from both a floristic and a vegetational point of view. Also the collection of quantitative data started. From 1987 up today several series of different data became available.

Data on biodiversity of Lake Ohrid and Lake Prespa

Abundance (individuals/m2) and biomass (g/m2) of macrozoobenthic taxa at soft-bottom stations along the Southern Bulgarian Black Sea coast (Burgas Bay), collected during field surveys of IBER-BAS in 2013-2014 as part of project PERSEUS. The dataset also contains measurements of several environmental parameters at the stations: sediment grain size (% gravel, sand, and silt/clay); sediment moisture content (%) and total organic matter (% loss on ignition); temperature, salinity and dissolved oxygen in the water column and near the bottom.

Map of the state of the soil use (SU). On each unit of SU, the Leaf Area Index (LAI) of the woody stand, and of the herbaceous strata in fallows and on millet in crop fields, biomass of grasses in fallows and of millet in crop fields, leaf area of millet, height of grasses in fallows and of millet in crop fields, and millet yield are measured each year.

Biomass data (g fw m-2) of macrophytes collected in 20 stations in the Mar Piccolo in the period February 1989-January 1990. Presence of species is indicated by 0,01 value In the period February 1989-January 1990, a sampling campaign was carried out in the Mar Piccolo of Taranto, to assess the biodiversity of unattached macrophyte populations. A stratified random sampling was performed in 20 stations variously distributed in the First and the Second Inlet. A total of 54 taxa were recorded: 15 Chlorophyta (included the rhizophytic Caulerpa prolifera), 5 Ochrophyta, 32 Rhodophyta, and unidentified colonial Bacillariophyta and Cyanobacteria. 3 species were non-indigenous (NIS). Considering the biogeographic element 2 species were Indo Pacific (IP), 18 species were Atlantic (A), 4 species were Mediterranean (M), 21 species were Cosmopolite (C), 4 species were Circum Tropical (CT) For the location of the stations see [Cecere E., Saracino O.D., Fanelli M., Petrocelli A. 1992 - Presence of a drifting algal bed in the Mar Piccolo basin, Taranto (Ionian Sea, Southern Italy).
