What habitat condition acts as the strictest boundary on the localized distribution of Jacanas?

Answer

The presence of suitable floating vegetation creating a continuous surface

Jacanas require calm water bodies where plants like water lilies create a continuous surface layer. The absence of this specific floating flora dictates their localized distribution more strongly than general climate alone.
