A total of 79 butterfly species from 3801 individuals were recorded. The riverine forest had the greatest diversity, with 54 species and 1611 individuals, and the least, the mosaic habitat, with 23 species and 659 individuals. The Shannon and Simpson indices were highest in the riverine, followed by wooded grassland and the mosaic habitat. There was a significant difference across land use types with Kruskal-Wallis of H=19.89 and p=1.274 E-05. The butterfly diversity varied with the month of sampling, such that January had the highest, followed by February, and the lowest was recorded in June. In riverine forest, the highest was recorded in January and the least was in June, while wooded grassland had the highest in January and the least was in March. In the mosaic habitat, January was the most abundant month, and May was the least abundant. Jaccard’s index of similarity indicated the lowest similarity was found between the riverine forest and the mosaic habitat. The number of butterflies showed a strong positive correlation with minimum and maximum temperatures and a strong negative correlation with average precipitation. The recent study found an important habitat for butterflies, but additional research is needed to find new species.

Agrochemicals are chemicals that are used in agriculture to protect crops from pests, diseases, and weeds, as well as to enhance crop yields. The use of agrochemicals has played a significant role in modern agriculture, enabling farmers to produce more food with less land and labour. However, the widespread use of agrochemicals has also raised concerns about their impact on human health and the environment.

In this paper, the effectiveness of three distinct layouts at a rooftop solar chimney's outlet sections is evaluated. The first arrangement resembles a typical home-solar chimney system. The technical literature serves as the foundation for the development of a numerical modelling that takes into account both the wind and buoyancy driving forces. An adequate two-transport equations model with a low-Reynolds treatment at the walls is used to replicate the airflow's turbulent nature. When simulating the wind numerically, extra effort is taken to accurately introduce the atmospheric boundary layer by using a logarithmic speed profile. It is necessary to impose a heat-flux heating condition (uniform) at the walls in order to accurately imitate the heating caused by irradiation. Attention is drawn to a comparative.

In marine ecology, linear regression is a statistical method that is commonly employed, either to describe straightforward correlations or as a part of more intricate models. This method's seeming simplicity frequently hides it’s much more complicated foundations, on which its validity and eventual ecological interpretations completely depend. With an emphasis on proper model specification, the various concepts of linearity, the problems with data transformation, the assumptions that must be respected, and regression model validation, we present a non-technical review of the fundamentals of linear regression and its application in marine ecology. R2 and p-values alone do not provide enough data to draw valid conclusions.
