The extraradical hyphae of arbuscular mycorrhizal fungi (AMF) one plant root system forage for the soil nutrients and induce colonization nearby plants, which leads to formation common networks (CMNs) that interconnect roots. Inoculation with AMF can increase length, surface area volume seedlings in nutrient-limited karstic soils. Mycorrhizal symbioses secrete glomalin help promoting aggregates...

Abstract This paper describes the relation of noble gas temperature (NGT) and mean annual air (MAAT) soil (MAST) through studying water samples meteorological data from six Hungarian regions. Alluvial plains, hilly mountainous regions were studied to investigate effects geomorphological, hydrogeological micro-climatic conditions. Water collected springs wells fed different aquifers. Comparing N...

Karstic cave systems in Slovenia receive substantial amounts of organic input from adjacent forest and freshwater systems. These caves host microbial communities that consist of distinct small colonies differing in colour and shape. Visible to the naked eye, the colonies cover cave walls and are strewn with light-reflecting water droplets. In this study, the diversity of prokaryotes constitutin...

Sulfidic redoxclines are a suitable niche for the growth and activity of different chemo- and photolithotrophic sulphide-oxidizing microbial groups such as the Epsilonproteobacteria and the green sulfur bacteria (GSB). We have investigated the diversity, abundance and contribution to inorganic carbon uptake of Epsilonproteobacteria in a meromictic basin of Lake Banyoles. CARD-FISH counts reveal...

The marine Lake Rogoznica is a small, karstic habitat with potential anthropogenic influence, situated in the eastern-central Adriatic coast. In this naturally eutrophic, hypoxic and periodically anoxic lake, an investigation of the microplankton community was performed during the 19951998 period when the ecology of the lake was greatly influenced by strong stratification and the appearance of ...
