The research was carried out to discover the bacteria associated with suspended particulate matter in indoor and outdoor air, as well as to investigate their antibiotic susceptibility. The results revealed that the extent of outdoor air pollutants (i.e., PM<sub>2.5</sub>, PM<sub>10</sub>, HCHO, and TVOC) was significantly higher (p&lt; 0.01) than the extent of indoor air pollutants. Culturing the sample filter paper in Nutrient Agar (NA) media at two different temperatures, 25°C and 37°C, allowed us to measure the quantity of bacteria in the air. The concentration of bacteria was 622±22 CFUm<sup>-3</sup> at 26±2°C and 11±2 CFUm<sup>-3</sup> at 20±2°C in both outdoor and indoor air, respectively. Positive <em>Bacillus, Micrococcus luteus, Pseudomonas stutzeri </em>and <em>Brevundimonas diminuta </em>bacteria were identified. All of the identified bacteria were found to be pathogenic. Moreover, some of the identified bacteria showed resistance to some commercially available antibiotics, such as Cefixime, Ceftazimidine, Nalidixic acid, Ampicillin, Ciprofloxacin, Gentamycin, etc. The positive correlation between fine particles and the bacterial concentration (R<sup>2</sup>= 0.75 for indoor and R<sup>2</sup>= 0.68 for outdoor air) revealed that the bacteria were highly associated with fine particles than coarse particles. Furthermore, the number and growth of bacteria were affected by the meteorological parameters (i.e., temperature and relative humidity). The rise in relative humidity favoured the increase in bacterial concentration. Therefore, the risk of being affected by bioaerosol is higher in the wet season than that of the dry season.</p> <p>J.

As Influenced by Vermicompost Application Grown at Rooftop Of Chandpur Area 2022-06-09T06:02:03+00:00 Rikza IJ KN Nishi MK Rahman <p>A pot experiment was conducted during rabi season during 2020-21 at a rooftop of Chandpur 150 MW Combined Cycle Power Plant (CCPP) Area in Chandpur Sadar upazila under Chandpur district to study the impact of different dosages of vermicompost (VC) on the growth and yield parameters of green capsicum plants (<em>Capsicum annuum </em>L.). It was laid out in a randomized complete block design (RCBD) with three replications each of six treatments viz. T1: 0 ton VC ha<sup>-1</sup> (control), T2: 2.5 ton VC ha<sup>-1</sup>, T3: 5 ton VC ha<sup>-1</sup>, T4: 7.5 ton VC ha<sup>-1</sup>, T5: 10 ton VC ha<sup>-1</sup>, and T6:15 ton VC ha<sup>-1</sup>. Results revealed that maximum plant height (38.53 cm), number of leaf plant<sup>-1</sup> (80), and highest number of branches plant<sup>-1</sup> (6) were recorded in T5 followed by T3. The highest values for rest of the growth and yield parameters were found from the plant receiving VC at the rate of 5 ton ha-1 (T3), such as, longest leaf per plant (12.84 cm), highest number of branches plant-1 (6), maximum girth (3.53 cm), maximum number of fruits plant-1(7), average fruit weight (44.75 g fruit-1), maximum weight of fresh (320.28 g fruits plant-1) and dry (4.43 g fruits plant-1); and maximum total fresh (109.40 g) and dry weight (21.03 g) of plants. Highest fruit length (18.97 cm) and diameter of fruit (7.30 cm) were recorded in T5 and T4, respectively. Almost all of the growth and yield parameters were observed lowest in control (T1). Study indicates that supreme dose of VC 15 ton ha<sup>-1</sup> in T6 yielded lower performance compare to 10 and 5 ton VC ha<sup>- 1</sup>. Considering the overall performance, it may be concluded that vegetative growth and yielding capacity of green capsicum plants can be boosted up by applying vermicompost at the rate of 10 ton ha-1 and 5 ton ha<sup>-1</sup>, respectively. This new information will be beneficial for growers, researcher and relevant workers.</p> <p>J. Biodivers. Conserv. Bioresour.

Barangay Bugsoc had the highest diversity H (2.09) as well as species richness (10); Barangay Omjon also had a species richness of 10, both of these areas are forested and riparian areas. Abundance of the number of individuals and number of species geared towards mixed vegetation forest and riparian areas at elevation ranging from 400-600 masl. High species diversity, evenness and richness (Shannon-Weiner, Shannon evenness and Menhinick richness indices) were observed on areas with minimal anthropogenic disturbance. The distribution pattern can be linked to the influence of resource accessibility and microclimatic conditions available for direct utilization by the species. Conversely, areas with high disturbance, such as agricultural and grassland areas, showed high dominance of <em>Rhinella marina</em>, an introduced species.</p> <p>J. Biodivers. Conserv. Bioresour.

This preliminary study focuses on the distribution and ecology of macrofungi in two sites in Northwester of Algeria. The mycological surveys carried out for the first time during two successive years made it possible to determine the fungal and floristic diversity as well as the climatic parameters and the physicochemical characteristics of the soil. The results indicate a good relation between the appearance of fungi and environmental factors. The fungal inventory carried out in the two study sites reveals a diversity of macrofungi comprising 44 taxa (84.09% basidiomycetes and 15.9% ascomycetes) distributed in 24 genera and 17 families. This diversity of the macrofungi identified is also linked to the density of the plant cover made up of three strata: tree, shrub and herbaceous.</p> <p>J. Biodivers. Conserv. Bioresour.

The treatments were T1: control, T2: 100% RDF + 0% effluent, T3: 50% RDF + 25% effluent, T4: 50% RDF +50% effluent, T5: 50% RDF + 75% effluent, T6: 50% RDF + 100% effluent. All the treatments had significant positive effect over control on dry matter yield and nutrient content of jute vegetables on non-contaminated soils. But in contaminated soils effluent irrigation showed negative effect on dry matter yield and nutrient content of jute leaves vegetables over control. The highest yield of dry matter in both contaminated and non-contaminated soils were observed in treatment T2 (100% RDF + 0% effluent), which were1.81, 1.90, 1.86 and 1.69 t/ha in non-contaminated and contaminated soils of Narayanganj and Gazipur, respectively. Among the textile effluent treated pots T4 the gave second highest yield of dry matter yield which were 1.55, 1.77, 1.36 and 1.58 t/ha in non- contaminated and contaminated soils, respectively.</p> <p>J.

From July 2017 to June 2021 a research work was conducted in Kashipur Union, under Barishal district of Bangladesh. In total, 191 vertebrate wildlife species were recorded. 141 species (74.35%) were bird, 18 species (9.42%) mammals, 17 species (8.90%) reptiles and 15 species (7.85 %) were amphibians. The largest diversity of animals (148 species) and their abundance (n=1477) were counted in winter. Bird species diversity was high in winter (H=4.699, Ds=0.989) with winter migrants (24 species). The summer season had the most evenness (E= 0.7652). Among them, 82 (42.93 %) species of wildlife were very common, 20 (10.47 %) common, 36 (18.32 %) uncommon and 54 (28.27 %) were few. An amphibian species <em>Euphlyctis kalasgramensis </em>had the highest (24.95 %) relative abundance; <em>Hemidactylus frenatus </em>(22.60 %) (reptile); <em>Turdoides striata </em>(3.23 %) (bird); and <em>Rattus rattus </em>(21.94 %) (mammalian) species. Among the observed wildlife species, 183 (95.81 %) were classified as least concern followed by 4 (2.09 %) near threatened, 2 (1.04%) vulnerable and only one (0.52%) endangered.</p> <p>J. Biodivers.

To Various Organic Manures and Chemical Fertilizers 2022-06-09T06:02:12+00:00 Zaman H SJH Suchi N Tabassum MK Rahman <p>A pot experiment was conducted at the Department of Soil, Water and Environment, University of Dhaka, from 10 January to 24 February 2021, to evaluate the growth parameters, biomass production, and nutrient uptake of red amaranth (<em>Amaranthus tricolor </em>L.) as influenced by different types of organic manures manufactured by companies, <em>viz</em>. ACI, Agro, Kazi, Mazim, McDonald, Naafco, Paragon and Sharib, and by 50% of recommended dose of NPK fertilizers. The experiment consisted of ten treatments with three replications each and was laid out in a Completely Randomized Design (CRD). On the day of harvest, Naafco displayed the greatest number of leaves (10.67±2.31), the longest leaf length (8.60 ± 2.07 cm), and the largest leaf area (275.10±118.8 cm<sup>2</sup> plant<sup>-1</sup>), whereas the highest plant height (24.53±3.27cm) and stem girth (24.53±3.27cm) were observed in McDonald. Conversely, Kazi exhibited the poorest performance in all aforementioned parameters. Both the highest fresh and dry weights (10.75±6.09 g plant-1 and 1.31±0.87 g plant<sup>-1</sup> respectively) were recorded in Naafco treated plants, and the lowest weights in Kazi (1.98 g plant<sup>-1</sup> and 0.23 g plant-1 respectively). The highest total nutrient content (NPKS and Fe) (46.02 mg plant<sup>-1</sup>) in plants was found in Naafco, while the lowest was in Kazi (3.96 mg plant<sup>-1</sup>). Judging from the results, Kazi treated plants consistently showed the lowest growth, biomass, and nutrient accumulation.</p> <p>J. Biodivers. Conserv. Bioresour.

Bandarban is one of the hill districts of CHT with diverse natural resources and ethnic communities. This paper is based on the review of published papers, reports, books related to Bandarban district of CHT giving emphasis on the landscape, natural resources, and the indigenous peoples in the CHT. The available information is synthesized to understand the overall state of natural resources degradation with special focus on land, soil, forest, fisheries, and livestock, etc. The traditional agricultural system of jhum cultivation is not sustainable due to population pressure, reduction of fallow period and soil degradation. The paper also presented the major causes of resource destruction along with the opportunities and challenges to the existing natural resource management in Bandarban. The prolonged conflict of land tenure and settlement of plain land people needs to be addressed at priority basis for the betterment of the hill people.</p> <p>J. Biodivers. Conserv. Bioresour.
