Antibiotic residues have been found in environmental samples, such as water, soil, and even food, usually come from wastewater, presenting human health risks. This study aimed to improve the elimination of antibiotics tetracycline (Tet) chloramphenicol (Chlor) by modifying three factors: contact time (3–7 days), plant biomass (10–14 g), antibiotic concentration (5–15 mg/L Tet 10–20 Chlor). An a...

Abstract The Anzali international wetland is a valuable habitat to wide variety of aquatic flora and fauna. This ecosystem being threatened due various pollutants particularly the heavy metals discharging from different point non-point sources. Concentration (Cr, Pb, Hg, Cu, Zn, Cd, Ag Ti) was examined in water body Azolla filiculoides (an exotic fern wetland). samples regarding A. were randoml...

Non-native aquatic plants are amongst the major threats to freshwater biodiversity and climate change is expected facilitate their further spread invasiveness. To date, in Croatia, no complete list of non-native extant horizon has been compiled nor a risk screening performed. address this knowledge gap, 10 14 plant species were screened for invasiveness Pannonian Mediterranean regions Croatia u...

Cyanobacteria are able to form stable nitrogen-fixing symbioses with diverse eukaryotes. To extend our understanding of adaptations imposed by plant hosts, two-dimensional gel electrophoresis and mass spectrometry (MS) were used for comparative protein expression profiling of a cyanobacterium (cyanobiont) dwelling in leaf cavities of the water-fern Azolla filiculoides. Homology-based protein id...

Nearly 230 species of biting midges have been recorded or described from Argentina; 38 of them are known from the Buenos Aires province and only one is cited from Martín García Island. This paper presents the results raised from six collecting trips which took place on the island during spring 2005, summer 2006 and autumn 2009. Diverse sampling sites including permanent and temporary aquatic en...

A phylogeny for all extant species of the heterosporous fern genus Azolla is presented here based on more than 5000 base pairs of DNA sequence data from six plastid loci (rbcL, atpB, rps4, trnL-trnF, trnG-trnR, and rps4-trnS). Our results are in agreement with other recent molecular phylogenetic hypotheses that support the monophyly of sections Azolla and Rhizosperma and the proposed relationsh...

In order to understand the physicochemical mechanisms that could explain the massive growth of Azolla arctica in the Eocene Arctic Ocean, we carried out a laboratory experiment in which we studied the interacting effects of rain and wind on the development of salinity stratification, both in the presence and in the absence of a dense Azolla cover. Additionally, we carried out a mesocosm experim...
