Warmer colours = where fixes cluster most — basking banks & resting pools returned to repeatedly.
sparsehotspot
Each fix coloured by season. Monsoon = high water (Jun–Sep); dry = low water & peak basking (Oct–May).
Gharials live only in the river, so home range is the length of channel occupied (river-km), not an area. Each coloured ribbon is one animal's stretch of river, drawn offset so overlaps are visible.
Each line is one gharial's position along the river over time. Flat = site fidelity; slopes = travel; where lines meet, animals shared a reach (possible encounters).
Transmitter temperature is a basking proxy: in sun it climbs above water temperature. Left = time-of-day (diel) basking curve; right = seasonal cycle. Absolute values differ between transmitters, so compare shapes, not levels.

Vertical axis is distance along the Chambal; upstream (west) at top, downstream (east, toward the Yamuna) at bottom.
Basking & transmitter temperature
Mean transmitter temperature by time-of-day and by month — a proxy for basking activity.
Diel curve — mean temp by hour
Seasonal cycle — mean temp by month
