Impact of improved ocean initial condition on the seasonal prediction of Indian summer monsoon
<p><span><span><span><span><span><span><span><span><span><span><span><span>In this study, an effort has been made to show the impact of improved ocean initial condition in the coupled forecast system (CFSv2) on the seasonal prediction skill of Indian summer monsoon rainfall (ISMR). CFSv2 is used as an operational dynamical model for the seasonal prediction of ISMR. The new improved ocean initial condition is based on <span>Global Ocean Data Assimilation System</span> (GODAS) analysis and is produced by assimilating vertical profiles of observed temperature and salinity from all the sources (XBTs, buoys and Argo profiling floats) over the global ocean using 3Dvar assimilation scheme and MOM4p1 ocean model. This new analysis is improved compared to the NCEP GODAS which uses earlier generation MOM4p0d and assimilates observed temperature and synthetic salinity. Twin sets of identical model experiments differing in initial conditions (IC) with the former (later) using NCEP IC (new IC; NIC) are performed. The NIC experiment shows consistent enhancement of ENSO skill compared to NCEP IC. This advancement leads to the improvement of ISMR skill. We found that the significant improvement of surface and sub-surface temperature, thermocline depth, and heat content over the global ocean particularly in the Nino3 region in the NIC compared to NCEP IC contributed to the improved ISMR skills. This enhanced ISMR skill score might be the result of reduced model drift in the NIC even on 4 month lead and capturing the ISMR – ENSO teleconnection with great fidelity.</span></span></span></span></span></span></span></span></span></span></span></span></p>

Comparative biogeography and the evolution of population structure for bottlenose and common dolphins in the Indian Ocean
<p><span><span><span><span><span><span><span><span><span><span><span><b>Abstract</b></span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Aim: </b>In the marine environment, where there are few physical boundaries to gene flow, there is often nevertheless intraspecific diversity with consequences for effective conservation and management. Here we compare two closely related dolphin species with a shared distribution in the Indian Ocean (IO) to better understand the biogeographic drivers of their population structure.</span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Location:</b> Global oceans and seas with a focus on the Indian Ocean</span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Taxon:</b><i> Tursiops</i> sp. and<i> Delphinus</i> sp.</span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Methods:</b> Bayesian, ordination, assignment, statistical and phylogenetic analyses to assess phylogeography, connectivity and population structure using microsatellite and mitochondrial DNA genetic markers.</span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Results:</b> Both <i>Tursiops</i> sp. and<i> Delphinus</i> sp. showed population structure across the western IO and, in each case, populations in the Arabian Sea (off India, Pakistan and Oman) were most differentiated. Comparisons with other populations worldwide revealed independent lineages in this geographic region for both genera. For <i>T. aduncus</i>, (for which multiple sites within the IO could be compared), Bayesian modelling best supported a scenario of expansion southwards following a bottleneck event resulting in differentiation between the northern and western IO. For <i>Delphinus</i>the same pattern is even more pronounced. Populations in the Arabian Sea region of the northwestern IO show genetic isolation for each of the two genera, consistent with other studies of cetacean species in this region. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Main Conclusions:</b> We propose that changes in the intensity of the southwest monsoon during the climate cycles of the Pleistocene could have affected regional patterns of productivity and represent an important biogeographic driver promoting the observed patterns of differentiation and population dynamics seen in our focal species. Patterns of population genetic structure are consistent with phenotypic differences, suggesting an influence from distinct habitats and resources, and emphasising the need for effective conservation measures in this geographic region. </span></span></span></span></span></span></span></span></span></span></span></p>
