    Abstract: UDK 595.384.1:591.134(282.249 Neretva) Specimens of white-clawed crayfish have been cought during from May to August 2011. The specimens were fished out from the tributaries of the river Neretva: Neretvica, Sistica and Kraljuscica. The study was done on 100 m of waterstream, where an unequal numbers of individuals was determined. 31 individuals was found in river Neretvica, 10 individuals in river Sistica and 4 in river Kraljuscica. Different hydromorphological characteristics of the waterstream have largely contributed to the different population abundance of this crayfish. Morphometric analysis included six parameters: (TL) total length [cm], (W) weight (gr), (ARL) carapace length [cm] , (CPW) carapace width [cm], (ROL) rostrum length [cm] , (ROW) rostrum width [cm], (CLL) claws length [cm] and (TEL) tail length [cm]. Total body length of the white- clawed crayfish varied from 4.3 to 8. 6cm, while the individual with maximum length was found in river Neretvica. Weight of the individuals varied from 5g to 26g. Weight is the parameter with the highest coefficient of variation where differences in weight were found in the individuals of equal length. According to the shape (length and width) of the rostrum, crayfish from river Neretvica and Kraljuscica had higher similarity than recripocally than with the individuals cought in river Sistica (isosceles triangle). The connection between body length and carapax width had been determined by linear regression, as well as the connection between body length and claws length. Condition index values are higher in males than in females and the male domination was express in all three watercourses, as well as in the overall sample (28males and 17 females).

    Abstract: Vegetation‐plot records provide information on the presence and cover or abundance of plants co‐occurring in the same community. Vegetation‐plot data are spread across research groups, environmental agencies and biodiversity research centers and, thus, are rarely accessible at continental or global scales. Here we present the sPlot database, which collates vegetation plots worldwide to allow for the exploration of global patterns in taxonomic, functional and phylogenetic diversity at the plant community level. Results sPlot version 2.1 contains records from 1,121,244 vegetation plots, which comprise 23,586,216 records of plant species and their relative cover or abundance in plots collected worldwide between 1885 and 2015. We complemented the information for each plot by retrieving climate and soil conditions and the biogeographic context (e.g., biomes) from external sources, and by calculating community‐weighted means and variances of traits using gap‐filled data from the global plant trait database TRY. Moreover, we created a phylogenetic tree for 50,167 out of the 54,519 species identified in the plots. We present the first maps of global patterns of community richness and community‐weighted means of key traits. Conclusions The availability of vegetation plot data in sPlot offers new avenues for vegetation analysis at the global scale.

    Abstract: Understanding drivers of success for alien species can inform on potential future invasions. Recent conceptual advances highlight that species may achieve invasiveness via performance along at least three distinct dimensions: 1) local abundance, 2) geographic range size, and 3) habitat breadth in naturalized distributions. Associations among these dimensions and the factors that determine success in each have yet to be assessed at large geographic scales. Here, we combine data from over one million vegetation plots covering the extent of Europe and its habitat diversity with databases on species’ distributions, traits, and historical origins to provide a comprehensive assessment of invasiveness dimensions for the European alien seed plant flora. Invasiveness dimensions are linked in alien distributions, leading to a continuum from overall poor invaders to super invaders—abundant, widespread aliens that invade diverse habitats. This pattern echoes relationships among analogous dimensions measured for native European species. Success along invasiveness dimensions was associated with details of alien species’ introduction histories: earlier introduction dates were positively associated with all three dimensions, and consistent with theory-based expectations, species originating from other continents, particularly acquisitive growth strategists, were among the most successful invaders in Europe. Despite general correlations among invasiveness dimensions, we identified habitats and traits associated with atypical patterns of success in only one or two dimensions—for example, the role of disturbed habitats in facilitating widespread specialists. We conclude that considering invasiveness within a multidimensional framework can provide insights into invasion processes while also informing general understanding of the dynamics of species distributions.

    Abstract: The Balkan Vegetation Database (BVD; GIVD ID: EU-00-019) is a regional database, which was established in 2014. It comprises phytosociological relevés covering various vegetation types from nine countries of the Balkan Peninsula (Albania – 153 relevés, Bosnia and Herzegovina – 1715, Bulgaria – 12,282, Greece – 465, Croatia – 69, Kosovo – 493, Montenegro – 440, North Macedonia – 13 and Serbia – 2677). Currently, it contains 18,306 relevés (compared to 9.580 in 2016), and most of them (82.8%) are geo-referenced. The database includes both digitized relevés from the literature (65.6%) and unpublished data (34.5%). Plot size is available for 84.7% of all relevés. During the last four years some “header data information” was improved e.g. elevation (now available for 83.4% of all relevés), aspect (67.7%), slope (66%), total cover of vegetation (54.3%), cover of tree, shrub, herb, bryophyte and lichen layers (27.1%, 20.1%, 40.2%, 11.5% and 2.1%), respectively. Data access is either semi-restricted (65.6%) or restricted (34.4%). Most relevés (84.6%) are classified to syntaxa of different levels. The database has been used for numerous studies with various objectives from floristic, vegetation and habitat-related topics, to macroecological studies at the local, regional, national, continental and global levels. During the last four years, BVD data were requested from 111 different projects via the EVA and sPlot databases.

    Abstract: UDK: 582.323: 574.4(497.6)(234.422)          551.438.22(497.6)(234.422) Peatland ecosystems in Bosnia and Herzegovina represent a relict remain of the vegetation, flora and fauna from the glaciation periods. Peatlands are widespread on the North, where they occupy large areas of northern Europe, Asia and Canada. Occurrence of this type of ecosystems in Bosnia and Herzegovina contains an indication of nature conservation in general and represents an extraordinary natural value. The status of peatland ecosystems in the Balkans should be carefully monitored especially today, at the time of the already recognizable effects of climate change. The preserved structure and functionality of these ecosystems might indicate satisfactory degree of resilience to climate change, but adverse state warns on the need to take appropriate actions. Multiply drivers as overexploitation of natural resources, water, air and soil pollution and spread of invasive alien species, also have a negative effect on peatland ecosystems. In order to assess the conditions of peatland ecosystems in Bosnia and Herzegovina, researches were carried out on Vranica and Zvijezda mountain in central Bosnia. Researches was conducted including the following communities: Sphagno-Piceetum montanum Stef 1964, Sphagnetum recurvo-subsecundi Grgić et al. 1991, Menyanthi-Sphagnetum Grgić et al. 1991 Scirpetum silvatici Ht et H-ić, Calthaetum rostratae Lakušić et al. 1991, Abieti-Piceetum illyricum Fuk. 1960 Stef. 62 s.l ect. To investigate existing conditions state of the peatland ecosystems, floristic elements and life forms were determined for every plant species. A comparison of previous and today’s state of these communities was conducted, associated with analysis of Ellenberg’s indices for temperature, light, soil reaction etc. According to Lakušić et al., 1991., these type of ecosystems in Bosnia and Herzegovina was satisfactory. However, today's finding shows severe changes. The loss of peatland habitats was recorded in the entire area of research. The main identified drivers are deforestation, habitat conversion and drainage of watercourses. In order to protect this type of ecosystems and important indicator species it is necessary to implement different conservation and restoration activities.
