ABSTRACT Karst environments preserve some of the best archives past climate, vegetation, hydrology, anthropogenic impact, and landscape evolution providing that a reliable chronology can be established. Here we present an example system Plitvice Lakes (Dinaric karst, Croatia), which is characterized by intensive tufa lake sediment formations. The radiocarbon dating method, combined with other m...

Rindifilum ramosum gen. nov., sp. un nouveau genre d'eau douce au sein des Ulvales (Ulvophyceae, Chlorophyta). Le présent article fournit une étude phylogénétique et morphologique de deux souches qui s'avèrent représenter espèce nouvelle, la famille Ctenocladiaceae (Ulvales). nov. se développe en association avec le Verrucaria Schrader, ascomycète lichénisé. Les reconstructions phylogénétiques ...

Biodiversité des Ulva L. en Méditerranée centrale: espèces cryptiques et signalements nouveaux. Certaines d'Ulva sont difficiles à identifier car elles cryptiques, soit par manque de caractères distinctifs, raison variation phénotypique intraspécifique. Cette étude documente deux nouvelles pour les îles maltaises: algues multicellulaires benthiques hétérokontes torta (Mertens) Trevisan californ...

Delftia acidovorans MC1 is able to grow on chlorophenoxy herbicides such as 2,4-dichlorophenoxypropionic acid (2,4-DCPP) and 2,4-dichlorophenoxyacetic acid as sole sources of carbon and energy. High concentrations of the potentially toxic organics inhibit the productive degradation and poison the organism. To discover the target of chlorophenoxy herbicides in D. acidovorans MC1 and to recognize...

Popularly known as stoneworts, brittleworts, muskgrass, muskworts or bass-weeds, Characeae are among the largest and most complex green algae. All common names come from some characteristics these plants may exhibit, such as the brittle, limestone (calcium carbonate) exoskeleton that can form on the external surfaces of the plant (e.g. Chara vulgaris and Chara globularis) and, particularly, fro...

Palaeoenvironmental research in the Southern Levant presents a series of challenges, partly due to the unequal distribution of palaeoenvironmental records and potential archives throughout the region. Our knowledge of climatic evolution, during the last approximately 25,000 years, is of crucial importance to understand cultural developments. More local, well-dated, multi-proxy studies are much ...

The study focuses on the present state and assessments of geotourism development two most representative tufa deposits in Djerdap National Park—the first UNESCO Global Geopark Serbia. findings were designated through implementing freshly upgraded methodology—M-GAM-1-2 based an early modified geosites assessment model (M-GAM). To overcome limitations previous model, authors implemented additiona...

Ostreobium is a genus of siphonous green algae that lives as an endolith in carbonate substrates under extremely limited light conditions and has recently been gaining attention due to its roles reef budgets association with corals. Knowledge about this remains fairly the scarcity strains available for physiological studies. Here, we report on 10 isolated from coral skeletons Great Barrier Reef...

We report results from geoarchaeological investigations at Cuncaicha rock shelter (4480 m above sea level) in the high Andes of southern Peru. Using field observations, geomorphological, micromorphological, micro-Fourier transform infrared spectroscopy, Bayesian modeling radiocarbon ages, and archaeological data, we analyzed entire stratigraphic sequence to determine depositional postdeposition...
