The ghara may enhance acoustic resonance during territorial displays.
During breeding season, mature male gharials establish territories along favorable river stretches. Dominant individuals use vocalizations amplified by the ghara and physical displays to deter rivals. Access to prime basking sites and nesting-adjacent waters increases mating opportunities. Territorial control may extend across significant lengths of uninterrupted river. Subordinate males are often excluded from optimal breeding zones. This spatial dominance shapes genetic contribution within populations. Territory size depends on habitat quality and population density.
💥 Impact (click to read)
Territorial monopolization concentrates reproductive success among relatively few males. In fragmented habitats, reduced territory size may intensify competition. If dominant males are lost to entanglement or disturbance, social structure destabilizes. Replacement requires years due to delayed maturity.
Breeding dynamics of this scale require long, connected river corridors. When dams and human activity compress territory boundaries, natural selection patterns shift. Conservation must consider behavioral ecology, not just population counts. A functioning social structure is as critical as raw numbers.
