Wild pigs are the most prolific, very intelligent and secretive species that over the recent past has been in a lot of conflict terms with the humans. These animals are adaptive generalists and survive in wide range of habitats worldwide. The reproductive traits of wild pigs are extraordinary showing high prolificacy so it becomes impossible to control their population. These animals have adapted to become nocturnal proving it difficult to know about their behavior. However in order in spite of these challenges the main objectives of this study was to understand the behavior and ecology of this particular species to come up the control strategies. Thus basis for documenting and understanding the wild pig behavior has dramatically evolved, contributing significantly to our understanding of these animals. In general, however, the lack of intensive field studies was attributed to the fact that wild pigs were regarded everywhere as a pest. The wild pig groups usually known as sounder's were tracked and all findings were documented. The study period was about a year and the wild pigs were tracked and observed at the adjoining regions of the Eastern Ghats (Sathyamangalam region) and the Western Ghats (Mudumalai tiger reserve, Anaimalai tiger reserve) and of Tamil Nadu state during November, 2012 to October, 2014. A variety of behaviors were documented such as social unit organization, Habitat utilization, Daily activity patterns, Movement patterns, Modes of mobility, Home range, Male-male competition, Maternal behavior, Resting/loafing beds, Mannerism and attitudes, Vigilance behavior, Vocalizations, Wallowing, Rubbing, Symbiotic grooming behavior, Scent marking, Senses. At the end of the study we were able to precisely outlay the above the entire behavior attributes of wild pigs. These findings are necessary to understand the wild pigs and their vermin nature to combat crop raiding, eventually cutting down Human-Wild pig conflict, that will a more scientific method of conservation to avoid conflicts ending in tragic outcomes.
Little is known about gastrointestinal parasite infections in wild ruminants. Faecal survey of parasitic prevalence plays an important role in wildlife management. The Wildlife interface regions, adjoining regions of forests serve as potential marker zones that serve to intermediate buffer zones that provide the viable ecology for the transit of various parasites between domestic and wild animals sharing the same landscape. Parasitic infections can cause disease and death in wild animals and can become a source of infection for domestic animals. Epidemiological studies are important to know about the status and transmission of these diseases. Parasitic diseases are best controlled by preventing the contact and parasite transmission between wild and domestic animals and by manipulating the factors involved in the disease transmission. The aim of this paper was to find out the prevalence of gastrointestinal parasites in gaur (bos gaurus) and domestic cattle at interface zones of the nilgiri hills. Qualitative examination of faecal samples from wild gaur (n=30) sharing ecosystem with domestic cattle (n=20) in the Nilgiri hills was done by Centrifugal sedimentation method and Floatation method. The prevalence was 63.3% and 80.0% in wild gaur and domestic cattle respectively with overall prevalence of 70.0%. The helminthes observed were trematodes (13.3%) include Fasciola sp. (3.3%), Amphistome sp. (6.7%) and Schistosoma sp. (3.3%), cestodes (20.0%) include Moniezia sp. nematodes (43.3%) include Toxocara sp. (6.7%), Strongyle sp. (23.3%), Oesophagostomum sp. (3.3%), Trichuris sp. (6.7%) and Mecistocirrus sp. (3.3%) and unsporulated Coccidia oocysts (13.3%) in wild gaur. It was concluded that, parasitic prevalence survey is vital in monitoring the impact on the health and maintenance of wild gaur population, and the prevalence of GI parasites recorded in the wild gaur and domestic cattle in the study areas shows the need to design and implement a control policy of helminth parasites in the Nilgiri hills.
Wild pigs are found to be the most prolific, very intelligent and secretive. These animals are adaptive ecological generalists and survive in wide range of habitats worldwide. The reproductive traits of wild pigs are extraordinary showing high prolificacy. Corticosteroids can exert inhibitory and facilitory effects on reproduction. In order to assess the attributable stress on reproduction a non-invasive method of assessing faecal glucocorticoid metabolites was applied in this study. Samples from wild pigs from three different regions were collected and were subjected to Enzyme Linked Imuno Sorbent Assay (ELISA). The purpose of this paper is to discuss the effect of stress on reproduction in wild pigs. Corticosteroids may act at the level of the ovary to suppress aromatase activity and thereby reduce the elevated circulating estrogens considered by many to be responsible for hyper secretion of Lutenizing Hormone (LH). Interestingly the acute level of stress is found to be facilitory and the chronic found to be inhibitory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
