    Opis:
    Jelutong Kapur and Sanaman are indigenous species at peat swamp forest. These plants have a great economic value. Besides the benefits from wood and sap, leaves can be used for medicinal purposes. The study aimed at obtaining the information related to the potential, distribution and increment diameter. This information was expected to be taken into consideration in the management and development of Jelutong. The study was conducted for 12 months in 12 observation plots, each plot measuring 100x100 m. The data were analyzed descriptively, while the growth patterns were shown graphically. The results showed that there were 100 Jelutong Kapur trees with a range 0–17 trees/plot, an average 8 trees/hectare. It was higher than Jelutong Sanaman, where there were 65 trees with a range of 0–13 trees/plot, an average 5 trees/hectare. However, jelutong Kapur had a diameter range 10.58–35.08 cm, the average increment diameter is 0.69 cm/year, the highest in the diameter class 10–15.9 cm and 22–26.9 cm which is 0.68 cm/year. It is lower than Jelutong Sanaman the diameter of which ranges within 12.61–37.13 cm, the average increment diameter is 0.77 cm/year, the highest increment in the class diameter of 10–15.9 cm is 0.85 cm/year. The highest and lowest number of trees is the same both in the diameter class 16–21.9 cm and 10–15.9 cm. The base area of Jelutong Kapur was 0.41789 m2/hectare, while in the case of Jelutong Sanaman it was 0.30422 m2/hectare. In both of them the 16–21.9 cm diameter class, is dominant, i.e. constitutes 40%. Both species may potentially support the economy for the local people, especially at forest periphery.

    Opis:
    The pond slider Trachemys scripta is one of the most widespread alien turtle species in the world. Its unregulated trade and the consequent uncontrolled releases into the wild led to negative impacts on the native turtles of the invaded areas. In Italy, alien pond sliders are widely spread, and the occurrence of hatchlings and well-established populations is known in some areas. However, to date in Sicily, only a single female of Trachemys scripta laying eggs was reported. Besides that, nothing is known about the actual reproduction success and establishment of self-sustaining T. scripta populations in Sicily. Therefore, based on 14 previously characterised highly polymorphic microsatellite loci, we aimed to unravel if the alien turtles successfully reproduce in Sicily, in both natural and semi-natural areas (i.e., lake “Biviere di Gela” and “Parco d’Orléans”, respectively). Our results show a clear structuring of the two studied populations. Several full-sibling relationships between the sampled turtles were found, suggesting actual reproduction in the wild of the pond sliders in Sicily. However, further sampling is desirable since no parent-offspring relationships were observed in the studied populations. Due to our results, systematic monitoring of alien pond sliders in the whole of Sicily is crucial for better planning of mitigation strategies in order to protect the native biota of Sicilian inland waters.

    Opis:
    A dinoflagellate identified as Prorocentrum dentatum, P. shikokuense or P. donghaiense is responsible of massive harmful events. Blooms of a species identified as P. shikokuense have been recently reported in the Mediterranean Sea, and an exotic origin, tentatively introduced by ballast waters from Asia, has been hypothesized. The molecular data based on the small-, large subunit, and internal transcriber spacers ribosomal RNA gene (SSU-, LSU-, ITS rRNA) sequences confirmed P. shikokuense in the Mediterranean Sea. The Mediterranean ribotype is identical to a subtropical North Atlantic ribotype, and with slight divergence from the numerous sequences from the Pacific Ocean. To revisit the relationship between P. shikokuense (=P. donghaiense) and P. obtusidens, we provide the first micrographs of P. dentatum and P. obtusidens, the latter collected from the type locality. Our observations indicate that P. dentatum, P. obtusidens, and P. shikokuense are three different species. Their diagnostic morphological characters are: Prorocentrum dentatum is 44–60 μm long, leaf-shaped, pointed and central posterior end, conspicuous anterior shoulder; P. obtusidens is 33–41 μm long, irregular parallelepiped, almost paralel valve margins, eccentric and pointed posterior end, moderate anterior shoulder; and P. shikokuense is <25 μm long, sunflower seed-shaped, round and centric posterior end, inconspicuous anterior shoulder.

    Celem pracy jest określenie przydatności wskaźnika BPL (ang. biopollution level index) do oceny stanu biozanieczyszczenia polskiej części Zalewu Wiślanego. Na podstawie danych z lat 2010 i 2012 w akwenie odnotowano łącznie 15 gatunków makrozoobentosu, w tym 5 zaliczono do grupy gatunków nierodzimych: Marenzelleria neglecta, Rhitropanopeus harrissi, Potamopyrgus antipodarum, Dreissena polymorpha i Rangia cuneata. W oparciu o przyjęte kryteria i dane literaturowe dotyczące wpływu obcych gatunków na środowisko, stan biozanieczyszczenia Zalewu Wiślanego został oceniony jako średni.
    This paper presents biopollution assessment results with respect to macrozoobenthic non-indigenous species in the Polish part of the Vistula Lagoon. A biopollution level index (BPL) was applied and evaluated based on the studies on macrozoobenthos conducted in 2010 and 2012 within the frame of several individual projects. Overall 15 macrozoobenthic species were identified, 5 of which were aquatic alien species: Marenzelleria neglecta, Rhitropanopeus harrissi, Potamopyrgus antipodarum, Dreissena polymorpha and Rangia cuneata. According to the applied criteria the Vistula Lagoon was moderately influenced by invasive species.

    Opis:
    Until recently only two palaemonid species inhabited the southern Baltic: Palae- mon adspersus and Palaemonetes varians. Soon after the year 2000 a new species – Palaemon elegans – arrived and quickly established itself as a new component in the trophic web. The objects of this research were to define the energy value and energy resources of P. elegans and to compare them with the corresponding values for the native P. adspersus. These parameters will supply information about this new link in the trophic web and may help to explain the part played by the new prawn and its population in the energy flow. This work demonstrated that the energy values of both prawn species were very much the same: the average energy value of P. elegans was 16.5±2.1 J mg−1 DW (19.3 ± 2.5 J mg−1 AFDW) (N = 150), that of P. adspersus was 16.7 ± 2.1 J mg−1 DW (19.5 ± 2.5 J mg−1 AFDW) (N= 71). No statistically significant differences in energy value were found between the two species with respect to sex, size or season. The results show that P. elegans is an energetically valuable food item for predators. Its energy resources in Polish brackish coastal waters can be as high as 150 kJ m−2; the highest among the palaemonid species in this area, they constitute a rich supply of food for other organisms.

    Opis:
    Non-indigenous gammarid species: Pontogammarus robustoides (G.O.Sars, 1894), Obesogammarus crassus (G.O. Sars, 1894), Dikerogammarus haemobaphes (Eichwald, 1841) and Dikerogammarus villosus (Sowinsky, 1894) are present in the Gulf of Gdańsk (southern Baltic Sea). These species reached the Gulf of Gdańsk by 2010 near the point where the River Vistula flows into the Baltic Sea, and become constituents of the amphipods in shallow bottom. All the gammarid species found are of Ponto-Caspian origin. They have been able to move across Europe along rivers and canals, and inhabit reservoirs and drainage systems in the vicinity of such waterways. D. villosus is the latest gammarid species to have colonized Poland. The floods that afflicted Poland in May and June 2010 could have had a significant influence, intensifying as they did the inflow of water from the Vistula into the Gulf of Gdańsk. This could have accelerated the arrival of individuals of these species. The water salinity at the sampling stations was 5.8 – 6.1 PSU. The possible invasion of non-native gammarids may have important consequences for the benthic fauna communities in the Gulf of Gdańsk.

Gatunki te pojawiły się w Zatoce Gdańskiej w 2010 roku, niedaleko ujścia Wisły do Bałtyku i stały się składnikiem obunogów płytkiego dna. Wszystkie wymienione gatunki są pochodzenia ponto-kaspisjkiego. Przedostały się do Europy rzekami i kanałami, i zasiedlają zlewnie tych rzek. D. villosus jest najnowszym przybyszem, który skolonizował Polskę. Najprawdopodobniej powódź, która dotknęła Polskę w maju i czerwcu 2010 roku zintensyfikowała napływ wód Wisły do Zatoki Gdańskiej. Przyśpieszyło to przedostanie się osobników wymienionych gatunków do Zatoki Gdańskiej. Zasolenie wody na stacjach zbioru materiału wynosiło od 5.8 do 6.1 PSU. Inwazja nierodzimych gatunków kiełży może znacznie wpłynąć na zespoły bentosowe Zatoki Gdańskiej.

    Opis:
    Palaemon elegans, a new component of the Gulf of Gdańsk macrozoobenthos, colonised the southern Baltic coastal zone in the late 20th and early 21st century. Analysis of the stomach contents of P. elegans revealed 16 plant and animal taxa that these prawns had fed on. The principal dietary component was detritus, with a mean frequency of occurrence in stomachs of > 80%. The most frequently occurring plant components in the diet were algae from the genus Cladophora and the family Ectocarpaceae, while the most significant animal components were Harpacticoida, Chironomidae, Ostracoda and Gammarus spp. The results of the study show that the dietary composition of P. elegans differed significantly between stations and months. The foraging area consisted of two distinctive regions – the Inner Puck Bay, and the Outer Puck Bay together with the Dead Vistula River; two of the stations – Gdynia and Sopot – were distinct from all the others. However, no obvious seasonality in the food composition could be demonstrated.

    Opis:
    Viral diseases have been prevalent in most parts of the tropics for ages, resulting to serious fatalities especially in Sub-Saharan Africa. However, different communities in most parts of Africa have discovered various medicinal plants capable of treating these diseases. Therefore, this study deals with the utilization of plant species employed in treating some of the identifiable viral diseases in Southwestern Nigeria. Data were collected through the use of structured questionnaires and oral interview. Results obtained from this work revealed that a total of 55 medicinal plant species belonging to 35 families were identified. The study revealed some of the parts of the plants used in treating viral infections and their uses.

    Opis:
    The two dipterocarp species, Dipterocarpus alatus and Hopea odorata, have been widely planted in degraded forest land in Southern Vietnam in the last decades. However, study on growth characteristics of these species and their associated factors is still limited. Therefore, the present study aimed to examine growth performance in different stand densities, and classify tree quality in 28-year old D. alatus and H. odorata plantations. Our results of analysis of covariance (ANCOVA) indicated that in pure stand aged 28 years, D. alatus outperformed H. odorata in tree growth, biomass and volume. In addition, except for four growth variables including tree height at the first branch (Hb), crown length (CL), crown ratio (CR) and linear crown index (LCI), the remaining variables were negatively affected by stand density. We observed that medium quality trees occupied the greatest proportion in both D. alatus (47%; n = 425) and H. od- orata (50%; n = 400). Except for CR and LCI, the class of good quality trees had the greatest values in the remaining examined growth variables. In linear discriminant analysis (LDA) model, the classification accuracy of testing set was relatively high in both D. alatus (85%) and H. odorata (91%). The most impor- tant variables for tree quality classification in D. alatus were crown diameter (CD) and diameter at breast height (DBH). Meanwhile, the most important variables in H. odorata were CD and tree height (H). These obtained results suggest that controlling crown size is important for shaping individual tree quality. Our data evidenced that D. alatus and H. odorata planted in Southern Vietnam with density equal or less than 500 trees per ha could yield high proportion of good and medium quality trees.
