| dc.description.abstract | Abstract Functional diversity reflects functional characteristics and their responses to environmental changes. For the study, four season's data was taken in the Panaha River of Gulmi District, form April 2023 to January 2024. This research involved the analysis of functional diversity and detailed exploration of the interconnection between functional traits and environmental conditions. To determine potential variations among environmental conditions a one-way ANOVA was done. Species and environmental variables were analyzed through multivariate analysis, canonical correspondence analysis (CCA) and intra- traits relationships were evaluated using principal component analysis (PCA). The research shows a diverse aquatic ecosystem hosting 19 fish species from 4 different Orders and 6 Families, with a total of 836 individuals collected fish. Seasonal variations showed the highest species diversity in summer. Schizothorax plagiostomus (20.93%) and Garra rupecula (19.62%) were the most dominant species. Cypriniformes (74%) appear as the dominant order and Cyprinidae (53%) being the most species rich family. Comparative analysis on functional traits among the species shows Mastacembelus armatus as the largest species, while Schistura species was the smallest in measurement. Body shapes, position in water, caudal fin types, and mouth orientations appear diverse among the fishes .Canonical Correspondence Analysis (CCA) show the EC, velocity, temperature, width are highly associated and influence factors for change in fish functional traits. PCA provide interrelationships among morphological traits, indicating strong positive correlations among certain traits and negative correlations with some others. This study provides the essential information for maintaining healthy aquatic ecosystems and biodiversity in the region. Knowledge on functional diversity play key role for identifying particular important species, evaluating ecosystem health and increase conservation efforts. | |
