<p>This study examined the variety and abundance of land snails in a specific rice field located in Lower Katingawan, Midsayap, Cotabato. Land snails are mollusks that dwell on land and possess spiral shells on their backs. Notably, no published research is available on land snails in the municipality of Midsayap, North Cotabato. The study identified three noteworthy species of land snails in the selected rice field, namely Paropeas achatinaceum, Achatina fulica, and Pomacea canaliculata, totaling 1048. The study utilized the quantitative-descriptive method and computed the diversity indices. Simpson's index was calculated, indicating a low probability of two randomly chosen individuals belonging to the same taxon. Shannon's index yielded a value indicating relatively low species richness and uneven distribution of individuals among taxa. These findings offer valuable insights into the community's structure and ecological significance, emphasizing the need for further research to comprehensively understand its diversity and dynamics.</p> <p><strong><em>Keywords:</em></strong> Biology; diversity indices; shells; snails; taxonomy; terrestrial ecosystem</p>

<p>The aim of this study was to assess the environmental pollutants present in the cobwebs found in selected lecture rooms; Mathematics lecture room (MTH), Chemistry lecture room (CHM), Biology lecture room (BIO) and Environmental Science lecture room (EMT) in the Faculty of Science, Federal University Dutse. Bacterial pollutants coupled with Arsenic (As) Lead (Pb) in the sampled cobwebs were isolated and identified using standard procedures. One-way Analysis of variance was used to determine the variation in the concentrations of Pb and As in the sampled cobwebs. <em>Staphylococcus aureus</em> (28.1%), <em>Bacillus</em> sp. (37.5%), <em>Streptococcus</em> sp. (18.8%), and <em>Streptobacillus</em> sp. (15.6%) were detected in all the cobwebs samples. MTH 4 had the highest Pb concentration (1.2800 mg/kg) while CHM 3 had the lowest (0.470 mg/kg) Pb concentration. CHM 3 and BIO 3 had very low concentrations of Pb, which were significantly different from each other (p˂0.05). This study has revealed that spider cobwebs can be an effective bio-indicator in determining indoor air quality.</p> <p><strong>Keywords:</strong> Indoor air, Cobwebs, Lecture rooms, Bacterial contaminants, Lead, Arsenic</p> <p>&nbsp;</p>
