DIVERSITY AND RESIDENTIAL STATUS OF WADER BIRDS AT HODAL IN PALWAL DISTRICT, IN HARYANA, INDIA.

Waders belonging to order Charadriiformes are commonly found along shorelines and mudats that wade in order to forage for food (such as insects or crustaceans) in the mud or sand. Bogs, marshes, mudats, shorelines, ponds, and ooded areas are all popular habitats for wading birds. The waders include storks, spoonbills, cranes, herons, egrets and ibises. They have certain physical and behavioural adaptations for living on or near water. Wading birds depend on water as a source of food, shelter, and nesting sites. Wading birds wade into shallow water to obtain food, instead of swimming and diving in water in search of feed that is not found on land. If we study the morphology of wading birds, they have lots of characteristics and adaptations that are useful in a watery habitat. Long legs of the wading birds help them to keep their feathers high and dry when wading into water in search of food. A long neck and a long bill are adaptations that make it possible to strike at prey while walking around on long legs. The benets of wading bird′s long, thin, spread-out toes are three-fold: toes help them to keep their balance and also help them to walk in mud without sinking. While walking in water and mushy mud, thin toes are easier to lift and set down. Spread-out toes also prevent them from sinking into soft mud in the water and at the water's edge, and above all those toes also disperse the weight of these big, tall birds, helping them keep their balance over their long legs. Waders are ecologically dependent on wetlands, as they provide good habitat to them for feeding, roosting, breeding, nesting, pre-migratory requirements, migration and protection from predators. So, wet lands plays an important part in the life cycle of wading birds. Wetlands have got highest capacity and are often extremely rich in bird and animal life. The present study aims at the assessment of diversity and residential status of wading birds in Yamuna basin near Hodal in Palwal District. It is located at 27°53′39″N and 77°22′09″E having an average elevation of 190 meters. Many ornithologists pay lots of their attention on eld study of birds during the eighteenth, nineteenth and twentieth century and till today many more are involved in the study of avian diversity near rivers. Avian fauna of Kalesar forests in immediate vicinity of River Yamuna in Yamuna-nagar District has been analysed by Kalsi (1998). Kulkarni et al.(2011) reported 151 species of birds from river Godavari; Balapureet al. (2012) reported 63 avian species from river Narmada. Other workers like Bahuguna(2008), Taketal.(2010), Gupta & Kaushik (2011), Gupta et.al(2012), Anupma et al (2014), Ankita et al (2019) have studied wetlands birds in various regions along the banks of rivers.

SIMILARITIES BETWEEN EMPEROR CHANDRAGUPTA II (VIKRAMADITYA) AND EMPEROR JALALUDDIN MUHAMMAD AKBAR

In the history of a great country like India, there have been many rulers since ancient times who ruled different regions of India at different times. But few of these rulers are called great rulers. Maurya ruler Chandragupta Maurya and Emperor Ashoka, Gupta ruler Chandragupta II (Vikramaditya), Vardhana ruler Harshavardhana, Kushan emperor Kanishka, Satavahana ruler Gautamiputra Satkarni, Chalukya ruler Pulakeshi II, Chola rulers Rajaraja Chola and Rajendra Chola, Rashtrakuta ruler Amoghvarsh, Pratihar ruler Mihira bhoja, Mughal emperor Jalaluddin Muhammad Akbar are named. Among these great rulers of India were two rulers whose lives and work were very similar. The rulers were the Gupta emperor Chandragupta II (Vikramaditya) and the Mughal emperor Jalaluddin Muhammad Akbar. The similarity between Chandragupta II (Vikramaditya) and Jalaluddin Mohammad Akbar is that the grandfather of both the rulers was the real founder of their kingdom. Both the rulers came to power through struggle (war). Both the rulers were tolerant rulers. The empire of the two rulers extended from present day Pakistan in the north to the mouth of the river Narmada in the south and from the mouth of the river Ganga in the east to the mouth of the river Indus in the west. Art, architecture, etc. developed during the reign of both the rulers. Due to the excellent administrative system of both the rulers, their empire remained stable for many generations to come. The main similarity between the two rulers is that in the history of India, only this two rulars have the Navratna in their court.

A Study on Species distribution and Diversity of Macro-Fauna of River Tawa - A Tributary of River Narmada in Madhya Pradesh, India

This study is aimed to collect information about the macrofauna diversity of Tawa River. The Tawa River joins to Narmada at district Hoshangabad (Madhya Pradesh). During the study 8 sites were selected for the investigation . collections of samples were done from the eight sampling sites of the river. Collected samples were identified up to species level and their diversity and richness were analyzed. Shannon index for diversity and margalef index for richness were used for the study.Total 48 taxa of macrofauna have been recorded from the identified sampling stations. Benthic fauna of phylum Arthropoda was found in dominant position in the study and phylum Mollusca was found in second position.

Estimation of physicochemical characteristics and associated metal contamination risk in the Narmada River, India

River Narmada is the fifth largest holy river of Madhya Pradesh (M.P) flowing in the central part of India. The river receives large quantity of untreated/partially treated wastewater enriched with heavy metals and supplementary toxic organic pollutants. This study aims to assess the water quality status in river Narmada using indices like comprehensive pollution index (CPI), heavy metal pollution index (HPI), risk assessment index (RAI) and cancer risk index (CRI), for human use. The presence of faecal coliform and high chemical oxygen demand > 20 mg/L indicates that the water is unsuitable for drinking purposes. The average CPI and HPI evaluated to be 1.98, and 1.35, respectively signifies the moderately polluted river water. Considerably, the RAI > 1 and CRI > 1 is obtained at all sampling locations that alarms the possible cancer risk to human if untreated river water is used. Principal component analysis of data confirmed pollution in the river from both natural and anthropogenic sources. The strongest Pearson correlation coefficient between Cu-Pb (0.998) and Zn-Cu (0.986) indicates the input of wastewater in the river probably from electroplating industries. The river water is unsuitable for human intake. It is required to control direct flow of wastewater in river to restore ecological health.
