“…Water from the Žveplenica spring was filtered through a container equipped with 60 µm mesh (Pipan, ; Iepure and Oarga, ) to collect the fauna. Water samples were collected from three locations: the orifice, the pool close to the spring orifice (approximately 0·2 m downstream) and sulfidic water from the seep that was above the spring orifice.…”

Assessment of the physical environment of epigean invertebrates in a unique habitat: the case of a karst sulfidic spring, Slovenia

A well‐fissured and faulted karst area at the Žveplenica sulfidic spring created suitable conditions for epigean copepods. Their presence in sulfidic water is a rare phenomenon. To understand the conditions related to sulfidic habitats in the region, two additional springs were analysed: the Studenec karst spring and the Sovra artesian borehole, which contains dissolved sulfide. Water temperature, chemistry and the stable isotopes of oxygen and hydrogen show that the Sovra borehole water has a different origin and history to that of the Žveplenica and Studenec springs water, which is derived from local precipitation. The low slope of the δ18O–δ2H regression line for the Žveplenica spring indicates a mixing of local precipitation water with geothermal sulfidic water that may explain the presence of live copepods. These harpacticoid and cyclopoid copepods must have survived anoxia and high sulfide for some time. The mean transit time for Žveplenica spring cannot be defined precisely from the available data, although the degree of attenuation of the isotopic signal indicates mean transit times of about 1·0 to 1·5 years. Sites similar to Žveplenica spring should be carefully analysed because not only do they provide insights into biodiversity but they also represent an ecotone between the anoxic/oxic and high/low sulfide of these karst waters. Copepods in similar geological settings can be used as additional parameters to evaluate conditions in subsurface sulfidic habitats and their spatial connectivity and responses to hydrological events.

“…Freshwater‐originated cyclopoids are relatively well represented in the whole Carpathian arc. High diversification has occurred in Acanthocyclops (17 species, of which 16 are narrow‐range endemics), especially in the Apuseni Mountains, where karst fragmentation has probably contributed to microallopatric speciation through population fragmentation and isolation by distance (Iepure, ; Iepure & Defaye, ; Iepure & Oarga, ). The Acanthocyclops genus includes several species from the Tertiary that require warmth to survive in the Romanian Carpathians but whose centre of speciation is considered to be the Balkan Mountains in Serbia and Bulgaria.…”

It is assumed that the south-eastern Europe and especially the Romanian Carpathians were important regions for surface and underground invertebrates survival during glacial periods and acted as a source of post-glacial colonization processes. We analyzed data from 233 georeferenced records for 164 species of groundwater copepods and ostracods from Romania and used a comparative approach to recognize the determinants of the regional-scale richness, endemism, and distribution patterns, with a primary focus on species from the Carpathian Mountains. In addition, we examined the driving forces for the observed pattern of distribution and richness linked to contemporary (groundwater habitat fragmentation and heterogeneity, climate, vegetation) and historical (past climate and vegetation) environmental conditions. Our analyses showed that: (1) species richness was high, irrespective of habitat heterogeneity, in karst and non-karst areas; (2) the main driver accounting for high species richness in the karst landscape was the rainfall regime (> 1350 mm per year), whereas, in non-karst areas, it was woodland vegetation; and (3) there was significant species richness and richness of phyletic lineages in hypothetical forest glacial refugia of the Carpathian arc. The combination of the distribution pattern, diversification, and evolution of stygobite lineages provides reliable evidence for species persistence in the Romanian groundwater during Pleistocene.

“…Samples for meiofauna were taken from all selected pools after microbiological sampling was finished. Water (4-8 litres) was filtered through a bottle equipped with 60 μm mesh on 2 sides which allowed water to pass through, but retained organisms (Pipan, 2005;Oarga, 2006;Iepure and Oarga, 2011). The volume of filtered water from pools was used to estimate abundance of individuals per sample (Table 1).…”

Air and water habitats in the Great Cavern of Santo Tomás were investigated using cultivable indicator microbial groups. In addition, cave pools were sampled to evaluate the biomass and diversity of aquatic meiofauna. In the climatically dynamic entrance part named Cueva de las Antorchas, concentrations of total cultivable airborne bacteria ranged from 2 to 15 CFU/20 cm 2 /20 min, and of airborne yeasts and moulds from 2 to 23 CFU/20 cm 2 /20 min. Different pools fed by constant percolation water or occasional underground floods were sampled. Microbial indicators of water habitats (total bacteria, coliforms, Escherichia coli, Enterobacteriaceae) showed that microbial load very likely depended on the sampling position in the vertical transection of the cave system and closeness to the entrance. During the underground flow of Santo Tomás Stream through the cave system, the concentration of isolates typical for E. coli was reduced from 56 CFU/ml at the ponor in Valle de Santo Tomás to a concentration below the detection limit at the spring in Valle de Quemado. In some cave pools, apart from microorganisms, aquatic fauna contribute highly to the total biomass. Investigation for aquatic meiofauna diversity in cave pools revealed relative high abundances of copepods and ostracods.
