Opis:
In the middle of January 2021, the survey of terrestrial and waterbird species wintering on the Mazovian Lowland was conducted. The controls covered 18 rivers (in total 1220 km), the largest towns, dam reservoirs, and other smaller water bodies. The results collected on selected river sections and water bodies were submitted to a country-wide project - Wintering Water Bird Survey (MZPW). January 2021 was mild, and throughout the surveyed period the average tem- perature was around 0°C. 102268 individuals of 48 waterbird species were recorded wintering in the monitored area. The most abundant were: Mallard Anas platyrhynchos (69.8%, N = 71383), Great Cormorant Phalacrocorax carbo (6.8%, N = 6.998), Common Goldeneye Bucephala clangula (4.9%, N = 4969), Goosander Mergus merganser (2.9%, N = 2970), Greylag Goose Anser anser (2.9%, N = 2946), and the Mute Swan Cygnus olor (2.5%, N = 2552). 68 “terrestrial” bird species were recorded and their total number was 29.039 individuals. The most abundant were: Fieldfare Turdus pilaris (20.5% of the total bird number, N = 5957), Eurasian Siskin Spinus spinus (11%, N = 3201), Great Tit Parus major (7.2%, N = 2103), Western Jackdaw Corvus monedula (6.2%, N = 1807), and the Yellowhammer Emberiza citrinella (5.1%, N = 1487) – Table 2. The average bird density was 238 indiv./10 km. 120 volunteers took part in this winter bird survey.

Opis:
We investigated the diversity of testate amoebae in an urban stream located within the Igarapé São Francisco Environmental Protection Area in Acre, northern Brazil, during the dry season, and evaluated the factors mediating the structure of this protist community. We collected 108 water samples for the analysis of the testate amoeba community and the limnological variables at six sampling points on the stream, between July and September 2018. We used a Redundancy Analysis (RDA) to verify the influence of environmental variables on the protist community. We recorded 76 species of testate amoebae from eight families, with most records from the families Difflugiidae, Arcellidae, Centropydae and Netzeliidae. More than half (49) of the species were recorded in Acre for the first time. The abundance of the amoebae of the family Trigonopiridae was regulated by the dissolved oxygen concentrations and the pH, while that of the Netzeliidae, Difflugiidae and Lesquereusidae was influenced by the pH, chloride concentrations, and the depth and transparency of the water. In the case of the family Arcellidae, abundance was determined by the turbidity and transparency of the water and the nitrate concentrations, while that of Centropyxis sp. was associated with the concentrations of thermotolerant coliforms. These findings indicate that, while the São Francisco stream is subject to anthropogenic impacts, it still presents adequate conditions for these organisms in some of its stretches. The abundance of these amoebae was influenced primarily by the productivity of the system, as indicated by the high protist densities recorded in the areas in which primary productivity was highest. These findings support the use of these protists in studies that investigate the most appropriate indicator organisms that respond to anthropogenic impacts and shifts in environmental quality. The results of the present study demonstrated the importance of this aquatic ecosystem for the biodiversity of the study area, and the need to further expand our knowledge on the adaptations and interactions of the aquatic communities of the Amazon region.

Opis:
Deadwood is an important functional and structural component of forest ecosystems since it regulates nutrient cycling, serves as a carbon (C) pool, increases the C content in the soil, and is a source of resources, including water, for a wide range of saproxylic and non-saproxylic organisms. The abundance and diversity of wood-inhabiting fungi in six fallen, horizontally lying logs of Quercus petraea, in the 1st, 2nd and 3rd decay classes, in the Drawa National Park in Poland in 2015, were studied using the Illumina se- quencing technique. The total number of OTUs obtained (264 307) included sequences of culturable fungi (242 369 = 91.70%) and non-culturable fungi (7 056 = 2.66%). The dead oak wood was colonized by 277 taxa. Culturable fungi of Zygomycota, Ascomycota and Basidiomycota comprised 75% of taxa detected and were represented by 14, 139 and 53 taxa respectively. Non-culturable organisms were represented by 70 taxa. Fungi were classified into 18 groups: (i) typical soft rot fungi, (ii) phytopathogens potentially hazard- ous to trees, (iii) epiphytes and endophytes or weak, opportunistic pathogens, (iv) ectomycorrhizal species, (v) ericoid mycorrhizal species, (vi) crust fungi, (vii) resupinate basidiomycetes, (viii) saprotrophs and soil fungi, (ix) opportunistic human pathogens causing superficial or systemic mycoses, (x) pathogens of warm- or cold-blooded animals, (xi) ascomycetous yeasts, (xii) basidiomycetous yeasts, (xiii) antagonists of fungi, (xiv) producers of metabolites effective against pathogens, (xv) hyperparasites, (xvi) lichen-form- ing species, (xvii) partners of other fungi, (xviii) species rare or uncommon in nature. It was shown that: (i) coarse, woody debris of oak is host to abundant and diverse mycobiota, (ii) abundance and diversity of fungi increase with the decay continuum, (iii) oak logs can be a habitat of phytopathogens potentially haz- ardous to forest health, (iv) different phytopathogens favour wood in different decay classes, (v) abundance of pathogens decreases, and of ericoid mycorrhizal (or soil) species increases with the decay continuum. Maintaining different types of deadwood increases fungal diversity, but also the risk of diseases.

Opis:
In this study, comparative experiments were conducted on the recovery of quartz using flotation with different fluid inclusion abundances. A large number of fluid inclusions with various sizes have been found in natural quartz. Micrographs, inductively coupled plasma, electron probe microanalysis, homogenization temperature, Raman spectra, zeta potentials, X-ray photoelectron spectroscopy, scanning electron microscope, and energy dispersive spectrometer were used to characterize the fluid inclusions and quartz, as well as the adsorption tests and single mineral flotation experiments to investigate its floatability. The results demonstrated that it was more likely for quartz with higher fluid inclusion abundance to connect with Fe3+ sufficiently to achieve a high level of flotation recovery, due to the powerful collecting ability by sodium dodecyl sulphonate to Fe3+. Furthermore, the mechanism indicated that the adsorption between quartz and Fe3+ was a process of chemisorption.

Opis:
The phytoplankton abundance and physico-chemical parameters of Ifewara Reservoir, Southwestern Nigeria was studied for four months (February to December, 2015). Four sampling stations (designated Stations 1-4) were established along the horizontal axis of the reservoir - from inflow region to the dam site end. At each station, net plankton samples were collected by sieving 30 litres of water through a plankton net of 50 µm mesh size into 30 ml concentrate volume. These were then preserved in 5% formalin solution and later treated with Lugol’s solution and reduced to 3 ml for microscope observation. The results of the physico-chemical parameters showed that some were above recommended limits of the National Environmental Standards and Regulations Enforcement Agencies (NESREA) for drinking water and aquatic life. Sixty-nine (69) species of phytoplankton were recorded from the four investigated sampling stations. The abundance of phytoplankton was in the following order; Bacillariophyceae (90.84%) > Chlorophyceae (44.67%) > Cyanophyceae (10.69%) > Charophyceae (0.31%) > Euglenophyceae (0.12%) > Dinophyceae (0.06%) > Chrysophyceae (0.03%). The most abundant phytoplankton species was Fragilaria aceania, accounting for 74.28% of the total, followed by Cosmarium quadrum (13.04%), Rhizoclonium hieroglyphicum (11.97%) and Oscillatoria tenuis (8.03%). With regard to the horizontal pattern of variation along the reservoir, the highest phytoplankton abundance was recorded at the inflow basin and the lowest abundance at the dam site. Almost all the phytoplankton groups also had their highest mean abundance during the rainy season rather then during the dry season.

Opis:
Azotobacter spp. are soil bacteria capable of fixing atmospheric nitrogen and making it available to plants. This makes them microorganisms of hight importance to the agriculture. The distribution of these bacteria is a complicated subject and is correlated with diverse factors, witch determine the presence or absence of the bacteria in a specific soil. The soil properties as soil and fertility and climate conditions affect the abundance of diazotrophs. Research material consisted of 182 soil samples taken in 2015 from agricultural land in various voivodeships. The number of Azotobacter spp. was determined based on plate method. The presented study evaluated the abundance of Azotobacter spp. in various Polish soils and confirmed the relationship between soil properties and the presence of these bacteria. The studied bacteria were present in 37% of soil samples and numbers of these bacteria varied widely, from 3 to 10801 cfu g-1 of the soil. In the case of Azotobacter spp., soil acidity was also an important factor restricting the occurrence of these bacteria in soils.

Opis:
Study on the distribution and abundance of kob (Kobus kob) in Borgu Sector Kainji Lake National Park was carried out. The studies was undertaken to derive information on the abundance of kob in Kainji Lake National Park and also determine the distribution of kob, in the area. The methodology employed in the study includes the use of direct method of census. Line transects was established using a stratified random sampling procedure. The data collected were analyzed using the formula - Total Population Ý = R·Z and the program DISTANCE. The result gathered revealed that each of these habitats contains ample number of kob throughout the year. The total estimated population of kobs censured in all the unit area = 9432 kobs /3970.02 km2, while the mean estimated population density is 0.09 ± 0.05 per km2, and the mean estimated population was 392 ± 210.11. There is therefore a 95% certainty that the true population size lies between 109.78 and 107.15 confidence limit. There is a high significant different at (P < 0.05) between the habitat types on kob abundance between the various habitat types in KLNP. The distribution of the kobs indicates that they are clumped in distribution, having an average cluster size of 14.617 in wet season and 18.067 in the dry season,. In a nut shell if the kobs herd is maintained in the reserve. Eco-tourism based on kobs watching to yield economic benefit to Kainji Lake National Park, Niger state and the Nation at large will be achieved. Therefore there should be extended mentoring programme to all the sectors of the park. This will go a long way to check illegal activities such as over grazing, poaching and tree logging that is affecting kobs population in Kainji Lake National Park.

Opis:
Domestic wastewater in Gampong Garot, Aceh Besar Regency, Aceh Province, Indonesia is directly discharged to the Daroy River without any treatment process. Domestic wastewater from Gampong Garot has been one of the contributors to microplastics contamination in the Daroy River. The microplastics (MPs) contained in domestic wastewater might come from used soaps and detergent products, as well as the scouring of clothes during washing. Thus, this study aims to investigate the abundance of MPs in domestic wastewater in Gampong Garot. The sampling points were determined based on purposive sampling, with samples taken at the end of the main pipe that directly leads to the Daroy River. Organics in domestic wastewater were removed using 30% H2O2 liquid through a digestion process at a temperature of 75°C. MPs characteristics such as size, shape, and colour were visually analysed using a light binocular microscope at 100× magnification, while the polymer type was analysed using Fourier transform infrared (FTIR) analysis. The concentration of MPs in domestic wastewater in Gampong Garot was 30.238 ±1.228 particles∙(100 cm)-3 sample. The most common sizes of MPs were found to be in the range of 1,001-5,000 μm, while the dominant colour and shape were transparent and fibre-like. Polyester (PES) was the most detected type of MPs. These findings highlight the need for wastewater treatment before discharge into aquatic bodies.

The abundance, stem diameter and height of Pentaclethra macrophylla Benth and Parkia biglobosa Jacq was assessed in each of the five Local Government Areas (Ogoja, Yala, Bekwarra, Obudu and Obanliku) of Northern Cross River State, Nigeria using the Modified Whittaker Method. Two forest communities were chosen from each Local Government Area, constituting 10 sites. In each site a 30 × 90 m plot was laid out in a spoke design and tree species present on the plots were recorded. A total of 3, 4, 5, 7, 4, 5, 6, 5, 12 and 10 stands for P. macrophylla and 4, 5, 5, 6, 6, 6, 4,5,8 and 8 stands for P. biglobosa were recorded in Gbogbu, Omulako, Aragban, Abeya, Aguomoh, Ukpah, Alege, Beteh, Bechevie and Sankwala forests respectively based on the sampled plots. Results of population percentage frequency, density and abundance of the two tree species varied across the study sites. The highest percentage frequency recorded for the tree species was 24% while the lowest was 12%. The highest population densities of 1.6666/ha, 1.3333/ha and 1/ha were recorded for the tree species while the lowest was 0.5/ha. Results of abundance show that the species were mostly rare with abundance ratio of (1.00≤AR≤2.99). Results of diameter class sizes of the tree species encountered in this study show that there were trees with mature trunk size than wildlings. Majority of the trees of P. biglobosa and P. macrophylla were in the diameter class of 20 – 29 cm and 30 – 39 cm respectively while results of the height class of trees shows that the minimum and maximum height was 10 -19 ft and 20 -29 ft respectively. This study shows that the trees of P. macrophylla and P. biglobosa were mostly rare and are declining; this could be as a result of over exploitation.

Opis:
Studies was undertaken to derive information on the abundance, as well as the distribution of African elephants in the Sambisa-Amshaka Game Reserve. For the purposes of the study, the reserve was divided into zones that were then compared. The results reveal that Sambisa-Amshaka Game Reserve holds an ample population of both resident and migratory elephant throughout the year. A total number of 132 elephant groups were sighted during a drive of 29350 m. There is, therefore, a 95% certainty that the true population size lies between 60 and 70 confidence limits, and there is no significant difference P>0.05 between the zones in both elephant composition and distribution. In addition, 190 species woody plants were found browsed by elephant in the study area. Other grasses and forbs were also browsed. The problem facing elephants in the study area includes farming activities during the dry season that block the route the migratory elephants pass through, and also the drying up of rivers. We conclude that if the elephant herd is maintained in the reserve, eco-tourism based on elephant watching will yield economic benefits to the game reserve, the state and the Nation at large. Adequate protection of the elephant species in the reserve is therefore recommended.

Opis:
Phytoplankton composition was analysed in the Maltański Reservoir and the inlet and outlet of the Cybina River. Samples were collected from three sampling stations in November 2007, February, May and August 2008. Considerable changes in the qualitative and quantitative composition of the phytoplankton in the infl owing and outfl owing water and in the central part of the reservoir were noted. Among 142 taxa chlorophytes were the most numerous group. There were also groups represented by the large values of phytoplankton abundance and biomass such as Cyanobacteria in autumn, chrysophytes in winter, diatoms and cryptophytes in spring and chlorophytes in summer. The diff erences in the qualitative and quantitative composition of the phytoplankton among the analysed sampling stations were noticed. The species composition of the potamoplankton was changing as it passed through the reservoir along the course of the river. With regard to all seasons the lowest number of taxa were noticed in samples from the inlet. The most diversifi ed was phytoplankton composition in the reservoir. The highest similarity between the analysed stations was observed in the phytoplankton composition in the reservoir and outlet of the river from this reservoir.
