Biodiversity Patterns in the Sundarbans: A Geographical Analysis of Salinity Gradients and Ecosystem Dynamics

Abstract

The present study investigates biodiversity patterns in the Sundarbans from a geographical
perspective, emphasizing the role of environmental gradients in shaping species distribution. The
research adopts an observational ecological design with stratified sampling across low, medium,
and high salinity zones, and utilizes secondary data along with field-based modelling.
Quantitative analysis using Mean ± Standard Error (SE) reveals a significant decline in mangrove
species richness, tree density, and faunal diversity with increasing salinity, highlighting the
ecological sensitivity of the region. The findings demonstrate that geographical factors such as
salinity gradient, tidal inundation, soil characteristics, and climatic disturbances play a crucial
role in determining biodiversity patterns. The study further identifies critical zones requiring
conservation priority due to their ecological vulnerability. Overall, the research underscores the
importance of integrating geographical analysis and statistical evaluation for effective
biodiversity conservation and sustainable ecosystem management in the Sundarbans.
Conclusion: The study concluded that greater exposure to blue light screen is associated with
increased behavioral issues, which in turn aggravatessleep disturbances among adolescents.
