Abstract:
Climate change assessment at a local scale requires downscaling of general circulation models (GCMs) using various approaches. In this study, statistical downscaling using established machine learning techniques is compared with the proposed extreme gradient boosting decision tree (EXGBDT) technique. The Cauvery river basin in southern peninsular India, which is known for its frequent droughts and floods, was considered in this study. The ACCESS 1.0 CMIP5 historical GCM simulation was used for downscaling the local climate with the help of daily observation data from 35 stations located in the study zone. An intercomparison of model performance in predicting daily weather variables such as precipitation and average, maximum, and minimum temperatures over the upper, middle, and lower Cauvery river basin was performed. The findings show that mean-variance is around 15% and bias is negligible for the proposed EXGBDT model, which is better than other models under consideration. The NSE and R2 values range from 0.75-0.85 for both training and testing periods. The intercomparison of monthly mean values of observed and downscaled data for different sub-basins and parameters suggests higher model efficiency. The lower variance observed in the comparison of CLIMDEX indices suggests that the EXGBDT model performance is better in representing the local climatic condition.

Abstract:
The sedimentary sequence exposed in the erstwhile Tiruchirapalli district hosts a more or less complete geological record of the Upper Cretaceous-Tertiary period. Systematic field mapping, collation of data on the micro-meso scale lithology, sedimentary structures, petrography, faunal assemblage and facies relationships of these rocks, in the light of modern stratigraphic concepts, helped to enumerate the lithostratigraphic setup and depositional history of the basin. Spatial and temporal variations of the lithologies and revised stratigraphic units are presented in this paper. Many high frequency sea level cycles (presumably fourth or higher order) which stack up to form third order sea level cycles (six in number), which in turn form part of second order cycles (two in number), including seven eustatic sea level peaks, have been recorded in this basin. Trend analysis of sea level curves indicates a gradual increase of the sea level from Barremian to Coniacian and a gradual decrease from Coniacian to Danian. Such lasting sea level trends had their influence on the sedimentation pattern and facies association. It is inferred that depositional bathymetry was maintained at a shallow-moderate level, primarily influenced by a lack of major subsidence during the depositional history of this basin. The study also revealed a prevalent simple basin filling process and dominant control by sea level changes, rather than tectonic movements over the depositional regime.

Abstract:
The outline of Indian Plate in the Gondwanaland Plate mosaic has been reconstructed. The basic premise for the reconstruction lies in the identification of the suture zone along Indus-Yarlung tectonic zone and Indo-Burman range, both of which are wreathed with ophiolite complexes. The north eastern margin of the Indian part of the Gondwana Plate, which was ill-defined in many earlier reconstructions, is now more precisely delineated with the find of slide-generated olistostrom bodies representing plate marginal trench setting around Ukhrul-Paoyi-Kiphire area of the ophiolite belt of Manipur-Nagaland. The recent report of continental Gondwanas close to this suture zone lends credence to this palaeogeographic reconstruction. On the north, the continental sediments having distinct Gondwana entity rarely extend to the Tethyan basin and as such the Indus-Yarlung Suture truly delimits the Gondwana Plate domain. The Himalayan front is regarded as Tethys-facing margin of the Gondwana continent. Along the eastern margin of Indian Plate, rifting as a sequel to ocean floor spreading led to the evolution of coastal troughs of Cauvery, Palar, Godavari-Krishna and Athgarh which bears records of marine transgressions during Aptian-Albian time from a juvenile Indian Ocean. These oceanward tilted troughs may represents the rifted arm of a triple junction formed during the continental fragmentation. The discovery of such troughs in the Upper Assam and Bengal Basin suggests that the separation of India from Eastern Gondwanaland occurred in a NE-SW direction. The Cambay and the Kutch basins document similar evolutionary history along the western margin of the Indian Plate. As a consequence of crustal tension accompanying the fragmentation, the outpour of tholeiitic basalt took place in Rajmahal, Khasi-Garo-Mikir Hills and Upper Assam at 100-105 million years along the west coast. The earliest manifestation of volcanism has been recorded in Saurashtra which is considered to be contemporaneous with Rajmahal volcanicity. It is suggested that both the eastern and western margins of the Indian Gondwana Plate bear closely related records of fragmentation in the Early Cretaceous time.

Abstract:
We present here a detailed account of the diversity, distribution, threats, and conservation of freshwater fishes in the upper-catchment of the Kabini River in the Wayanad part of the Western Ghats Biodiversity Hotspot. A total of 136 fish species belonging to 13 orders, 29 families, and 69 genera were recorded. Order Cypriniformes dominated with five families, 36 genera, and 84 species, and Cyprinidae was the dominant family represented by 51 species within 21 genera. The true diversity of ichthyofauna in this catchment, is still unclear and requires further exploration and taxonomic studies. At least 44 species recorded during the study are endemic to the Western Ghats, of which 16 are endemic to the Cauvery River System and two species endemic to the Kabini Catchment. A total of 20 non-native fish species were recorded from the study area, of which six species were inter-basin (within India) transplants and 14 species were exotic. Among the native species with confirmed identity, four are Critically Endangered (CR) and nine Endangered (EN) as per the IUCN Red List of Threatened Species. As a part of the study, we also extend the distribution ranges of Opsarius malabaricus, Laubuka trevori, Opsarius bendelisis, Puntius cauveriensis, Oreichthys coorgensis, Mesonoemacheilus pambarensis, Hypselobarbus curmuca, and Pseudosphromenus cupanus to the Kabini Catchment. The presence of four species, which were earlier considered to be endemic to the west flowing rivers of the Western Ghats, viz, Laubuka fasciata, Hypselobarbus kurali, Sahyadria denisonii, and Puntius mahecola, in an east flowing stream is reported and discussed. Deforestation and removal of riparian vegetation, pollution, stream channel modification, sand mining, destructive fishing practices, dams and other impoundments, monsoon fishing, and non-native species are the major threats to freshwater fishes in the region. Strategies for the conservation of aquatic ecosystems in the Kabini Catchment are discussed.

Abstract:
The complex palaeogeographic history of India involving a gradual transition from Gondwana to Laurasia with an intervening phase of prolonged physical isolation, and the biotic signatures of this complex history as preserved in India’s Mesozoic fossil record are of much current interest and continue to be debated. Seen in this context, the fossil record of dinosaurs from India provides a unique opportunity to study their diversity and palaeobiogeographic distribution in time and space. The Indian fossil record, as currently documented, is patchy and restricted mainly to three intervals of the Mesozoic era: Late Triassic, Early/Middle Jurassic and Late Cretaceous. The Late Triassic–Jurassic record, representing a Pangean setting, is known primarily from the Gondwana formations of Pranhita–Godavari (P–G) Valley in the southern Indian state of Andhra Pradesh, although sporadic Jurassic occurrences are also known from Kutch (Gujarat) and Rajasthan. The earliest Late Triassic dinosaur fauna of India comes from the rhynchosaur–dominated Lower Maleri Formation of Carnian age. Known from fragmentary and isolated specimens, the Late Triassic dinosaur fauna is currently represented by the sole species Alwalkeria maleriensis, which is possibly a basal saurischian with uncertain relationships. A slightly younger dinosaur fauna from the archosaur–dominated Upper Maleri Formation of late Norian–earliest Rhaetian age consists of a more diverse assemblage including the two named basal sauropodomorphs (Nambalia roychowdhurii and Jaklapallisaurus asymmetrica). In contrast to the Late Triassic, the Early Jurassic record of Indian dinosaurs described from the Upper Dharmaram and Lower Kota formations of P–G Valley, is far more abundant, diverse and based on more nearly complete material that is currently referred to four named taxa of stem sauropodomorphs or basal sauropods (Lamplughsaura dharmaramensis, Pradhania gracilis, Kotasaurus yamanpalliensis, Barapasaurus tagorei) plus an ornithischian (Ankylosauria). Kotasaurus, one of the earliest known sauropods, is more primitive than Barapasaurus and shared numerous plesiomorphic characteristics with prosauropods. Together, the Late Triassic and Early Jurassic sauropods dinosaurs of India document the early radiation of this group. Amongst the other important records of Jurassic dinosaurs in India is the oldest known camarasauromorph sauropod whose identification is based on a metacarpal, a first pedal paw and a fibula from the Middle Jurassic (Bajocian) strata of Khadir Island, Kutch. Fragmentary postcranial skeletal material of an unidentified Middle Jurassic dinosaurs is also known from Kuar Bet (Patcham Island) in the Rann of Kutch and the Jumara area of Kutch Mainland.Post–Gondwana, the Late Cretaceous dinosaurs of India occur in a different geodynamic setting in which the Indian Plate, as traditionally considered, was a northward drifting island continent in the middle of the Indian Ocean. Apart from the solitary record of a Cenomanian–Turonian sauropod from Nimar Sandstone, Cretaceous dinosaurs from India are documented mainly by skeletal remains and eggs/eggshells from the Maastrichtian infratrappean (=Lameta Formation) and intertrappean deposits in the Deccan Volcanic Province of eastern, western and central peninsular India, and from broadly coeval Kallamedu Formation of Cauvery Basin, southern India. Skeletal remains of the Lameta dinosaurs belong to two major groups, titanosaur sauropods and abelisaurid theropods, plus a possible ankylosaur, whereas the Cauvery records include fragmentary titanosaur bones and a solitary tooth of a troodontid theropod. Apart from bones and teeth, a number of dinosaur egg–bearing nesting sites are also known to occur in the Lameta Formation of east–central and western India, extending for more than 1,000 km across the states of Madhya Pradesh, Gujarat and Maharashtra. Close phylogenetic relations of the Lameta titanosaurs and theropods with corresponding taxa from the Maastrichtian of Madagascar (Vahiny, Majungasaurus) and the rare occurrence of Laurasian elements such as a troodontid, pose interesting palaeobiogeographic problems in the context of India’s supposed oceanic isolation, especially after its separation from Madagascar at ~ 88 Ma.
