-Chara kokeilii A.Braun population, specimen and habitat characteristics from reported sites in SE Europe.
Source publication
A new site for stonewort Chara kokeilii A.Braun was recorded in a Mediterranean shallow lake Prološko Blato Retention, Croatia, SE Europe. The species was associated with the vegetation alliance Potamogetonion graminei Westhoff & Den Held. This record has been compared with four other sites (Albania, Bulgaria, Greece and Montenegro) from which the...

... samples for total nitrogen were stored at 4-8°C in dark bottles filled to the top, and analysed within 24 hours using a Shimadzu TOC-VCPH equipped with an analyser for total nitrogen. Water samples for ammonium, nitrate and orthophosphate analysis were immediately filtered on glass filters with 0.45 µm pores, stored at 4-8°C and analysed within 24 hours on ionic chromatographer (Dionex 3000). ...Context 2

In the Early to Middle Miocene, the post‐orogenic intramontane lacustrine Sinj Basin that belonged to the Dinarides Lake System evolved in the area of the External Dinarides. A composite 770 m thick stratigraphic column was measured spanning the basin's stratigraphy. Eight facies were differentiated. Four facies are almost entirely composed of fres...

While working on several projects dealing with the flora of Neretva River delta in south Croatia, interesting floristic discoveries were made. During fieldtrips, freshwater habitats (rivers, channels and lakes) were in the focus of the survey, and were studied in detail both from the boat and from the mainland. Altogether 69 plant taxa were recorded and are presented in the results, out of which 25 taxa associated with aquatic habitats (hydrophytes, helophytes and species of riparian habitats) were discussed in more detail. These taxa are rare, threatened, invasive, newly found or otherwise seen as important for the studied area and their distribution maps are also presented.
Rimac, A., Alegro, A., Šegota, V., Koletić, N. & Papp, B. 2021. Bryum klinggraeffii and Philonotis marchica – new to the bryoflora of Croatia. – Herzogia 34: 255 –266. Two new records for the still quite underexplored Croatian bryophyte flora are presented. The ephemeral colonist Bryum klinggraeffii was recorded in pioneer dwarf-cyperaceous vegetation along sandy banks of two lowland watercourses of Central and Eastern Croatia (Continental Biogeographical Region), while turfs of Philonotis marchica were found on submerged and exposed carbonate rocks in a fast-flowing karstic river in the mountainous region of Gorski Kotar (Alpine Biogeographical Region). Here we provide a detailed description of ecological conditions and a vegetation account for all sites of occurrence of these species in Croatia. These findings of quite rare species, especially P. marchica, which is listed as endangered on European level, also represent a valuable contribution to the bryoflora of Southeast Europe, the European region with the greatest deficit in knowledge of bryophytes.
