| Abstract |
Increased salinity distresses some key species severely in Indian Sundarbans. Geomorphic characteristics coupled with demographic obligations have proven to be pivotal factor towards the prevalence of elevated salinity in this zone. Better adaptation to rapid changes in microclimate demands wide range of genetic polymorphism as well. RAPD and ISSR molecular markers were used for this genetic diversity study. Degree of polymorphism was found relatively higher in Bruguiera gymnorrhiza (26.43 % in RAPD and 24.36 % in ISSR) than the other taxa, Heritiera fomes (14.43 and 12.76 % respectively) in case of RAPD and ISSR. Dendrogram constructed based on the similarity matrix showed that for H. fomes, least saline and highest saline zones are positioned in the same clade; whereas in B. gymnorrhiza the higher saline areas were clustered together. Nei's gene diversity (h) as revealed from RAPD and ISSR analysis were found to be 0.0821, 0.0785 and 0.0647, 0.0592 in B. gymnorrhiza and H. fomes respectively. The higher degree of polymorphism as revealed from UPGMA Dendrogram and Nei's genetic diversity might be attributed towards the comfortable growth of B. gymnorrhiza all along the Indian Sundarbans. On the other hand the relatively lesser degree of genetic polymorphism of H. fomes might be attributed towards their precarious status in present days elevated salinity in Indian Sundarbans. |

Attention Score in Context
This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 May 2016.
All research outputs
#2,943,607
of 22,829,683 outputs
Outputs from Physiology and Molecular Biology of Plants
#10
of 413 outputs
Outputs of similar age
#39,217
of 262,314 outputs
Outputs of similar age from Physiology and Molecular Biology of Plants
#1
of 6 outputs
Altmetric has tracked 22,829,683 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 413 research outputs from this source. They receive a mean Attention Score of 1.9. This one has done particularly well, scoring higher than 96% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 262,314 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 84% of its contemporaries.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
