Thymallus thymallus (Linnaeus, 1758), Ecological Status in Maramureş Mountains Nature Park (Romania)
2016
Abstract Thymallus thymallus is considered a species of significant protective importance within the Vişeu Watershed. The state of habitats characteristically inhabited by Thymallus thymallus within the Maramureş Mountains Nature Park is balanced between reduced (one third of the lotic sectors where the species was identified), average (one third) and good (one third). The excellent conservation status is currently missing for populations of this fish in the Vișeu Basin. Human impact types identified as contributing towards the decreasing state of Thymallus thymallus habitats and therefore populations in the studied area in comparison with its natural potential are: poaching, minor riverbed…

The role of anthropogenic habitats in freshwater mussel conservation
2018
The data that supports the findings of this study are available in the supplementary material of this article.

Abstract. Endolithic microbial communities are prominent features of intertidal marine habitats, where they colonize a variety of substrates, contributing to their erosion. Almost 2 centuries worth of naturalistic studies focused on a few true-boring (euendolithic) phototrophs, but substrate preference has received little attention. The Isla de Mona (Puerto Rico) intertidal zone offers a unique setting to investigate substrate specificity of endolithic communities since various phosphate rock, limestone and dolostone outcrops occur there. High-throughput 16S rDNA genetic sampling, enhanced by targeted cultivation, revealed that, while euendolithic cyanobacteria were dominant operational tax…
Bacterial diversity associated with poplar trees grown on a Hg-contaminated site: Community characterization and isolation of Hg-resistant plant grow…
2018
International audience; Industrial waste dumps are rarely colonized by vegetation after they have been abandoned, indicating biological infertility. Revegetation of industrial tailings dumps is thus necessary to prevent wind erosion, metal leaching and has been shown to restore soil functions and ecosystem services. However, little is known about the microbial colonization and community structure of vegetated tailings following the application of restoration technologies. In this study, we investigated the rhizosphere and phyllosphere bacterial communities of a poplar tree plantation within a phytomanagement-based restoration program of a Hg-contaminated site. We used Illumina-based sequenc…
Antibiotic Resistance of Gram-Negative Bacteria from Wild Captured Loggerhead Sea Turtles
2020
Sea turtles have been proposed as health indicators of marine habitats and carriers of antibiotic-resistant bacterial strains, for their longevity and migratory lifestyle. Up to now, a few studies evaluated the antibacterial resistant flora of Mediterranean loggerhead sea turtles (Caretta caretta) and most of them were carried out on stranded or recovered animals. In this study, the isolation and the antibiotic resistance profile of 90 Gram negative bacteria from cloacal swabs of 33 Mediterranean wild captured loggerhead sea turtles are described. Among sea turtles found in their foraging sites, 23 were in good health and 10 needed recovery for different health problems (hereafter named wea…
Barbus meridionalis Risso, 1827 populations status in the Vişeu River basin (Maramureş Mountains Nature Park)
2017
Abstract The ecological state of lotic ecosystems occupied naturally by Barbus meridionalis, in the Vişeu Basin within the Maramureş Mountains Natural Park, vary among good to reduced. The inventoried human activities which negatively influence the ecologic state of the Barbus meridionalis species habitats and populations are the organic and mining pollution, and poaching. The habitats with low and inadequate conditions created a reduced status of the Barbus meridionalis populations; the status of Barbus meridionalis populations is not so much affected in the cases of habitats of average to good condition. Barbus meridionalis is considered a relatively common fish species in the researched …
Augstā purva biotopu atjaunošana īpaši aizsargājamās dabas teritorijās Latvijā 2010-2013
2013
Purvs ir viena no jutīgākajām dabas ekosistēmām. Projekta mērķis ir atjaunot augstā purva biotopus četru dabas liegumu – Melnā ezera purva, Aklā purva, Rožu purva, Aizkraukles purvu un mežu – degradētajās platībās un pievērst sabiedrības uzmanību Latvijas dabas vērtībām.
Augstā purva biotopu atjaunošana īpaši aizsargājamās dabas teritorijās Latvijā
2010
Purvs ir mitra dzīvotne, kurai raksturīga aktīva kūdras veidošanās. Tā ir mājvieta daudziem augiem un dzīvniekiem, kuri nespēj dzīvot citur. Neskarti augstie purvi ir rets un apdraudēts biotops Eiropā. Nosusināšana, kūdras ieguve, mežu stādīšana un zemes rekultivācija pēdējās desmitgadēs ir nelabvēlīgi ietekmējusi purvus. Meliorācijas sistēmu ietekmes dēļ Aizkraukles purvā un mežos, Aklajā, Rožu un Melnā ezera purvā purva biotopi ir izmainījušies. Projekta mērķis ir atjaunot dabisko ūdens līmeni projekta vietās – augstā purva biotopos, kurus ir ietekmējusi nosusināšana – tādējādi aizsargāt Eiropas un Latvijas nozīmes purva biotopus, augus un dzīvniekus.
