Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay
Marine Ecology, Volume 46, Issue 2, March 2025.ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.
