A hitherto undescribed population of gobies in the Greek brackish karstic Lake Vouliagmeni was identified as Millerigobius macrocephalus. Molecular phylogenetic analysis using partial mitochondrial ribosomal DNA sequences situates this species as a sister taxon to Zebrus zebrus, thus confirming earlier morphological work. Morphological variation as compared to previous studies on this species is discussed. This is the first report of M. macrocephalus occurring inland and under oligohaline conditions, underlining that our knowledge on diversity and distribution of the European gobiid fauna is still far from complete. The occurrence of this rarely observed fish species might enhance the conservational importance of the lake under study. © 2011 Elsevier GmbH.

The present study provides the first quantitative assessment of cryptobenthic fish species diversity and abundance on hard bottoms below 20 m depth by examining Mediterranean underwater reefs with deep vertical cliffs. Quantitative sampling was performed at depths down to about 45 m and yielded 220 cryptobenthic and 61 epibenthic individuals belonging to 21 species, showing that the cryptobenthic fishes highly outnumbered the epibenthic individuals. The study highlights the high diversity and abundance of this unexplored part of the benthic fish community. The cryptobenthic fish assemblage was dominated by the family Gobiidae in terms of both biodiversity (>60% of all species) and abundance (>90% of all specimens). Fish species previously considered rare were present and some of them were even numerous in this assemblage. Three out of fourteen recorded habitat variables (depth, rocky cliff surface area vs. the bottom of the cliff area, and the presence of sand as the bottom substrate) were identified as significant for species occurrence. Species were generalist in their choice of shelters since the size and quantity of semi-caves, caves, cavities and even bio-cover type had no significant influence on the species distribution and abundance. © 2016 CSIC.

Gobioidei is one of the largest suborders of teleost fishes, with nearly 2000 extant species currently recognized. They have a worldwide distribution and show a spectacular variety in morphology, ecology, and behavior. Despite their importance, phylogenetic relationships among many groups of gobioids (including some of the major lineages) still remain poorly understood. In this study, we analyze sequence data of five molecular markers (two mitochondrial and three nuclear) averaging 6000. bp for 222 species of gobioids. Our study is the first to include both multiple nuclear and mitochondrial genes to reconstruct a comprehensive multilocus phylogeny of gobioids encompassing most major lineages representing the overall diversity of one of the most speciose vertebrate lineages. Two separate datasets are produced and used to specifically address the phylogenetic placement of Rhyacichthyidae and Odontobutidae, and the phylogenetic relationships among gobioid lineages. Our results strongly support that the initial split in the gobioid tree separated a clade containing Rhyacichthyidae. +. Odontobutidae as the sister group of all other lineages. The family Eleotrididae branches off the gobioid tree after the Rhyacichthyidae. +. Odontobutidae clade, followed by the Butidae as sister group to the Gobiidae. Additionally, several major monophyletic groups are confidently identified within the two major Gobiidae subclades, the gobiine-like gobiids and the gobionelline-like gobiids. Robustness of the phylogenetic trees inferred here is significantly higher than that of previous studies, hence our results provide the most compelling molecular phylogenetic hypothesis of Gobioidei thus far. For the first time, we provide a comprehensive sampling of European gobies that traditionally have been divided into "transverse" gobies and "sand gobies". We show that the European gobies cluster in three distinct lineages, the Pomatoschistus-, Aphia-, and Gobius-lineages. The former resolved within the gobionelline-like gobiids and the latter two within the gobiine-like gobiids. These findings have significant implications for our understanding of the phylogeographic origin of European gobies in the light of the closure of the Paratethys. A rogue taxon analysis identified Kraemeria as an unstable taxon decreasing support at the base of the gobiine-like gobiids. Removal of this rogue taxon significantly increased phylogenetic resolution in that part of the tree and revealed additional insights into early bursts of cladogenesis of the gobiine-like gobiids. © 2013 Elsevier Inc.

Phytosociology, ecology and chorology of snowbed vegetation in Croatia were researched. Snowbed stands, found only in freezing ravines and dolines of the Liburnian karst and Velebit Mountains (NW Dinaric Alps, NW Croatia), were classified into the association Drepanoclado-Heliospermetum (Salicion retusae, Arabidetalia caeruleae, Thlaspietea rotundifolii). Those stands, exposed mostly to the north and shaded for the majority of the growing season, were developed on more or less settled periglaciar screes and boulders in the coldest parts (bottoms, smaller ditches) of the dolines with long-lasting snow cover. Due to lower altitude of Croatian mountains, snowbed vegetation could be found only azonally, in freezing ravines surrounded by altimontane and subalpine (fir-)beech and spruce forests, where these stands manage to thrive due to specific microclimatic conditions. Snowbeds host some rare, endangered and/or protected plant species in Croatia. Vulnerability of the flora and vegetation of snowbeds in Croatia is briefly discussed. © 2010 Società Botanica Italiana.

Cryptobenthic fish communities are a rarely studied and ill-defined component of the marine benthos. Quantitative sampling of seventy-six 1 × 1 m plots at Cape Šilo, Northern Adriatic Sea, yielded 522 cryptobenthic and 67 epibenthic individuals of 27 species. Canonical Correspondence Analysis (CCA) identified variation of 3 out of 17 habitat variables (depth, presence of bedrock, and presence of short thallus algae on boulders) as significantly and strongly correlated with species occurrence. Interpretation of CCA triplots allowed the description of niches of the 13 most abundant species, as well as the tentative identification of three major habitat types structuring the cryptobenthic fish community (inclined bedrock, infralittoral algae, and the deeper infralittoral mixed bottom). The study highlights the largely unstudied ecological relevance of the cryptobenthic fish community as revealed by an unexpected high diversity and the numerical dominance of some species which previously were considered rare. An improved definition of cryptobenthic fishes is provided. © 2012 Springer-Verlag.


Data for four Brachiopoda species found in three new locations are cited: in a sediment sample from the sea cave Medova buža at a depth of one meter (Novocrania turbinata, Argyrotheca cuneata and Joania cordata), on an amphora fragment in Velo kolo at a depth of 25 m (Argyrotheca cuneata and Megathiris detruncata) and from Rab Island and in Unije channel at the depth of 52 m (Joania cordata).


This paper provides literature review data for Lutraria angustior Philippi, 1844 and Lutraria oblonga (Gmelin, 1791) in the eastern Adriatic Sea as well as new findings for this species. One bivalve specimen of L. angustior from the area of Vrulja (between Omis and Makarska) was collected by I. Bilopavlović, one subfossil specimen and two single shells were collected by D. Iglić in Novsko źdrilo. D. Marguš found shells of L. oblonga at the river Krka mouth, Ž. Krstinić three living specimens in the vicinity of Rab Island, and D. Iglić two subfossil specimens in Ljubač Strait.

The first quantitative sampling method for deep cryptobenthic and epibenthic ichthyofauna using trimix diving was performed at about 60 m depth at two localities off the island of Hvar (eastern central Adriatic Sea) in October 2014. The safe, efficient, and relatively simple diving technique combined with the quantitative method for collecting fishes on studied depths is described and explained. A total of 16 fish specimens representing four species, i.e., three gobiid and one blenniid species, were collected using anaesthetic quinaldine at six bottom quadrats (squares) of 1 m². The cryptobenthic and small epibenthic ichthyofauna on these habitats at circalittoral depths could not be efficiently sampled by any other method. Two of the collected species, Thorogobius macrolepis (Kolombatović, 1891) and Vanneaugobius dollfusi Brownell, 1978, are considered rare with very few reported records. The deepest findings of species Parablennius rouxi (Cocco, 1833), Gobius auratus Risso, 1810, and T. macrolepis were recorded. © 2016, Scientific Society of Szczecin. All Rights Reserved.

Mountain ranges in the circum-Mediterranean area, with the Balkan Peninsula in particular, are hotspots of European biodiversity, with the most remarkable element being the high level of endemism in the Balkan Peninsula. With the intention of explanation of this phenomenon, we use a model plant genus Wulfenia to address the objectives within the proposed project: (a) ascertainment of molecular phylogenetic hypoteses on the relationships of the study genus both to its closest relatives as well as within the genus; (b) testing the Pleistocene speciation hypothesis: long distance dispersal or vicarism?; (c) ascertainment of comparitive phylogeographic hypotheses within species and species groups; (d) identifying the putative centres of origin of the study group based on phylogenetic and phylogeographic patterns; (e) identifying the migration paths between the disjunct populations; (f) defining the timing of the colonisation of the present disjunct distribution range. All the material of the genus Wulfenia will be collected in the field, while that of the related genera also herbarium material will be used. Research will be carried out applying both classical [e.g. morphometrics, cladistics] as well as modern molecular methods [DNA-sequencing, cpDNA haplotype analysis, DNA-fingerprinting (AFLP), biogeographical analysis, molecular dating]. Our results, which are also of high relevance for conservation purpouses, will significantly contribute to a broader basis addressing the questions going beyond the study group, e.g., biogeography of the Middle East, southern Europe and Asia.
