Global tiger Panthera tigris populations mostly survive within the
geographically fragmented forest patches, thereby limited genetic exchange
between isolated populations. Assessing the genetic status of these
populations can reveal the effects of dispersal barriers and provide
critical insights to guide future conservation actions. Using
non-invasively collected biological samples, we investigated fine-scale
genetic structure of tigers in the Sundarbans mangrove forests intersected
by the complex river systems, and which holds one of the largest global
tiger populations. We genotyped 52 tiger samples at 10 polymorphic
microsatellite loci, and sequenced 33 of them for a total of 1,263
base-pairs at four mitochondrial gene fragments. Microsatellite analyses
exhibit a signature of fine-scale genetic structure, which might have been
the consequence of limited tiger dispersal due to wide rivers across the
Sundarbans. Similarly, mitochondrial data show a historic pattern of
population isolation that might be due to wider rivers across the entire
Sundarbans shared by Bangladesh and India. Given the intrinsic nature of
the mangrove habitat embedded with numerous rivers, increased commercial
traffic and human activities may further impede tiger dispersal across
wide rivers, escalating further genetic isolation of the Sundarbans
tigers.
