Emergence and Extinction of Dipterocarpaceae in Western India with Reference to Climate Change: Fossil Wood Evidences
Emergence and extinction of Dipterocarpaceae in western India with reference to climate change: Fossil wood evidences Anumeha Shukla∗, RCMehrotraand J S Guleria Birbal Sahni Institute of Palaeobotany, 53 University road, Lucknow 226 007, India. ∗Corresponding author. e-mail: anu [email protected] Climate has played a crucial role in assigning a different kind of topography to Rajasthan and Gujarat since the Cenozoic time. Evidently, three genera, namely, Dipterocarpus Gaert. f., Hopea Roxb. and Shorea Roxb. of the Dipterocarpaceae are described from the Neogene sediments of western India (Rajasthan and Gujarat). These taxa are marked by their complete absence in the region today. The presence of Dipterocarpaceae in western India has been noticed from the Early Eocene up to the Plio- Pleistocene in deep time. The family is usually a dominant component of the humid tropical and subtropical flora of the Indo-Malayan region and its discovery, along with earlier described fossils from western India indicates existence of ancient tropical rain forests in western India. A change in the climate affected warm and humid conditions occurring there during the Cenozoic resulting in arid to semi-arid climate at present which is responsible for the ultimate extinction of Dipterocarpaceae in the region. In addition, the palaeobiogeography of Dipterocarpaceae is reviewed. 1. Introduction understorey.

SAL Botanical Name: Shorea Robusta Family: Dipterocarpaceae Chromosome No.: 2N= 14
Dr. K.S. Yadav Assistant Professor (Horticulture) School of Agricultural Sciences & Technology RIMT University, Mandi Gobindgarh. SAL Botanical name: Shorea robusta Family: Dipterocarpaceae Chromosome no.: 2n= 14 Introduction: This tree is native to the Indian subcontinent, ranging south of the Himalaya, from Myanmar in the east to Nepal, India and Bangladesh. In India, it extends from Assam, Bengal, Odisha and Jharkhand west to the Shivalik Hills in Haryana, east of the Yamuna. The range also extends through the Eastern Ghats and to the eastern Vindhya and Satpura ranges of central India. In Nepal, it is found mostly in the Terai region from east to west, especially, in the Sivalik Hills (Churia Range) in the subtropical climate zone. There are many protected areas, such as Chitwan National Park, Bardia National Park and Shukla Phat Wildlife Reserve, where there are dense forests of huge sal trees. It is also found in the lower belt of the Hilly region and Inner Terai. Uses: It is a medicinal tree, and used in Ayurveda for thousands of years to treat variety of diseases including piles, leucorrhoea, gonorrhea, skin disorders, ulcers, wounds, diarrhea, dysentery, burning sensation, seminal weakness, etc. Sal is one of the most important sources of hardwood timber in India, with hard, coarse-grained wood that is light in colour when freshly cut, but becomes dark brown with exposure. The wood is resinous and durable, and is sought-after for construction, although not well suited to planing and polishing. The wood is especially suitable for constructing frames for doors and windows. The leaves are also used fresh to serve ready made paan (betelnut preparations) and small snacks such as boiled black grams, gol gappa, etc. -
Bengal Vegetation
Plant Formations in the Bengalian BioProvince Peter Martin Rhind Bengalian Tropical Evergreen Forest In places such as the Patloi Range and Naga Hills in the Assam Valley these forests are characterized by the giant dipteropcarps Dipterocarpus macrocarpus and Shorea assamica, which can attain heights of up to 50 m. They often occurs as emergents standing over a canopy at about 30 m. Common canopy trees are species of Mesua (such as M. ferrea) and Vatica (such as V. lanceaefolia), but many others occur such as Altingia excelsa, Amoora wallichii, Artocarpus chaplasha, Canarium species, Dysoxylum procers, Stereospermum personatum and the endemic or near endemic Mallotus roxburghianus (Euphorbiaceae). There is also a rich understory of bamboos, palms and shrubs such as Bambusa pallida, Livistona jenkinsiana, Pseudostachyum polymorphum and the endemic bamboo Dendrocalamus hamiltonii (Poaceae). Climbers and epiphytes are also well represented but the shaded ground layer can be almost devoid of plants. On the other hand, colourful species such as Thunbergia grandiflora may be present. In the upper Assam Valley these forests eventually give way to tropical evergreen forests of a lower stature. These include forests dominated by Kayea assamica (Kayea Forests), found on the northern bank of the Brahmaputra Valley, and forests dominated by species of Mesua (Mesua Forest), which occur, for example, in the foothills of the Balipara Frontier. Bengalian Tropical Semi-Evergreen Forest Forests made up of predominantly evergreen trees but with varying amounts of deciduous species extend from Puri in Orissa to Assam. The deciduous components include some of the more typical species and usually lose their leaves for a short period during the dry season. -

India: Kaziranga National Park Extension
INDIA: KAZIRANGA NATIONAL PARK EXTENSION FEBRUARY 22–27, 2019 The true star of this extension was the Indian One-horned Rhinoceros (Photo M. Valkenburg) LEADER: MACHIEL VALKENBURG LIST COMPILED BY: MACHIEL VALKENBURG VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM INDIA: KAZIRANGA NATIONAL PARK EXTENSION February 22–27, 2019 By Machiel Valkenburg This wonderful Kaziranga extension was part of our amazing Maharajas’ Express train trip, starting in Mumbai and finishing in Delhi. We flew from Delhi to Guwahati, located in the far northeast of India. A long drive later through the hectic traffic of this enjoyable country, we arrived at our lodge in the evening. (Photo by tour participant Robert Warren) We enjoyed three full days of the wildlife and avifauna spectacles of the famous Kaziranga National Park. This park is one of the last easily accessible places to find the endangered Indian One-horned Rhinoceros together with a healthy population of Asian Elephant and Asiatic Wild Buffalo. We saw plenty individuals of all species; the rhino especially made an impression on all of us. It is such an impressive piece of evolution, a serious armored “tank”! On two mornings we loved the elephant rides provided by the park; on the back of these attractive animals we came very close to the rhinos. The fertile flood plains of the park consist of alluvial silts, exposed sandbars, and riverine flood-formed lakes called Beels. This open habitat is not only good for mammals but definitely a true gem for some great birds. Interesting but common birds included Bar-headed Goose, Red Junglefowl, Woolly-necked Stork, and Lesser Adjutant, while the endangered Greater Adjutant and Black-necked Stork were good hits in the stork section. -

A Yellow-Throated Marten Martes Flavigula Carrying a Small Indian Civet Viverricula Indica
A Yellow-throated Marten Martes flavigula carrying a Small Indian Civet Viverricula indica Babu Ram LAMICHHANE1*, Chiranjibi Prasad POKHERAL1, Ambika Prasad KHATIWADA1, Rama MISHRA2 and Naresh SUBEDI1 Abstract Yellow-throated Marten Martes flavigula has a wide geographic distribution, but little is known about its ecology and behaviour. A camera-trap survey in and around Chitwan National Park, Nepal, photographed a solitary Marten carrying a Small Indian Civet Viverricula indica. The animal was in a grassland patch amid Sal Shorea robusta forest. It is unclear whether the Marten killed the Civet. Recent camera-trap surveys suggest that Yellow-throated Marten is widespread in Chitwan NP with records from altitudes of 190–675 m; many records are from Sal forest.

High Dominance of Shorea Robusta Gaertn. in Alluvial Plain Kamrup Sal Forest of Assam, N
International Journal of Ecosystem 2012, 2(4): 67-73 DOI: 10.5923/j.ije.20120204.04 High Dominance of Shorea robusta Gaertn. in Alluvial Plain Kamrup Sal Forest of Assam, N. E. India Jyotishman Deka*, Om Prakash Tripathi, Mohamed Latif Khan Department of Forestry, North Eastern Regional Institute of Science and Technology, Itanagar, 791109, Arunachal Pradesh, India Abstract The study emphasizes on the community characteristics of naturally regenerated sal forest of Kamrup district, Assam, India. Sal is one of the most important timber yielding plants and also good source of aromatic gum and non- tim- ber forest product. These forests are exposed to over-exploitation, deforestation, encroachment and alteration in land use and land cover and in return being replaced by secondary regenerated sal forest. Altogether, 71 plant species were recorded from the selected sal forest. Herbaceous layer of the forest was most species rich (30 species) layer followed by tree and shrub species. Leguminosae and Asteraceae were among the most dominant families in the forest while large number of families was monospecious. Shorea robusta has contributed about 90% of the total stand density (2559 individual ha-1) of the forest, while species like Erythrina suberosa, Delonix regia and Pterospermum acerifolium were represented by single stem. Similar to that of stand density, sal have contributed to the maximum basal area of the forest. The girth class distribu- tion confirmed a reverse J-shaped distribution, with higher density in lower girth classes and sharp decline thereafter. Total density of shrubs and herbs was recorded 2 individuals m-2 and 63 individuals m-2, respectively. -
