  • Three species of amphibians and eleven species of reptiles have been documented in the White Mountains area. The relatively low number of herpetofauna species is due to the infrequency of surface water in the White Mountains. All of the species monitored are common throughout Greece. Aside for the terrestrial reptiles and amphibians, there monitoring (presence/absence) is also being performed for the Loggerhead turtle (Caretta caretta) in the coastal front of the National Park.

  • The dataset contains number of plant species, diversity (within habitat), number (and type) of layers, presence/absence (and type) of management, presence/absence (and type) of natural disturbances, aboveground biomass by indirect methods, presence/absence of groundwater table and presence/absence of susceptibility of the site to drought. Sampling plots are the same used for biomass and LAI measurements in the Orgovány LTER (KISKUN LTER) grassland. The aim of the yearly biomass and LAI measurements in the grasslands is to study the effect of weather to the plant production along a productivity gradient. Aboveground living plant biomass and LAI data from 24-30 grassland patches in Orgovány region of Kiskunság (Kiskunság National Park) along a productivity gradient from open sand grassland to reedbed, yearly from 2003 to 2012, were sampled approx. at the time of maximum aboveground biomass. The size of the patches are 20 to 50 sq-m, and each year one 0.5 by 0.5 m sampling unit is selected within each patch. The patches are permanent ones; some of them were omitted and replaced because of disturbance in several years. The aboveground living plant biomass data of separate species are submitted in HU_SI001199_species_biomass_20130508 dataset, and the EUNIS habitat types of the sampled patches are submitted in HU_SI001199_eunis_habitat_type_20130508 dataset.

  • Abundance (individuals/m2) and biomass (g/m2) of macrozoobenthic taxa from seagrass meadows along the Southern Bulgarian Black Sea coast (Burgas Bay), collected during field surveys of IBER-BAS in 2013-2014 as part of project PERSEUS. Due to the sampling method (hand corer), the dataset represents the infauna associated with the seagrasses. 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 and salinity of the water.

  • Terrestrial molluscs present an increased level of endemism, which reaches almost 33% of the species in the southwest area of the White Mountains. The unique topography and complexity of the Cretan mountains provides ample refuges for terrestrial snails.

  • 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.
