**Abstract**

Habitat loss due to human activities and climate change is synergistically posing serious threats to the global biodiversity leading to irreversible extinction of several species. In wake of recent extinction, several forests are declared as protected areas where no more human activities are allowed. However, the scope of these protected areas got broadened from mere conservation to poverty alleviation and sustainable development during the past decades. Though these protected areas seem to be supportive of the biodiversity conservation, several challenges and gaps have emerged that need to be addressed for effective conservation and sustainable management in these protected areas. Therefore, the present chapter aims to address the roles, challenges, and approaches for conservation, and sustainable management in protected areas of India. Based on the published literature, we have found that protected areas proved to be a successful strategy for the conservation of wild animals and plants. However, management of poaching, man-wildlife conflicts, funding, extensive resource use, and tourism is still a challenge for some national parks of the country. Although governmental policies have addressed some of these challenges, only limited success has been achieved so far. Therefore, further studies need to assess the efficiency of protected areas for biodiversity conservation and devise the mechanisms for effective sustainable management of these protected areas.

## **1. Introduction**

The variability in all life forms at different scales on the earth is collectively termed as biodiversity. Further, biodiversity is not evenly distributed on the globe as tropical regions are relatively more diverse than other geographical regions. It is an integral component that ensures and sustains our own life by providing necessary services from oxygen to clean water and from food to clothing. Despite their central role in sustaining life, species are disappearing at alarming rates, and it has

been estimated that about 27% of the total species are facing threats to extinction [1]. Much of today's large-sized vertebrate animals represent less than 5% of their historical ranges. Many species such as the greater one-horned rhino (*Rhinoceros unicornis*), Asiatic lion (*Panthera leo persica*), and the hard-ground barasingha (*Rucervus duvaucelii branderi*) are restricted to microscopic remnants of their historical range. The biggest threats are posed by habitat destruction by human activities together with changing climatic conditions. Therefore, there is an urgent need to take measures to protect biodiversity in order to sustain life on earth.

Several strategies and measures have been proposed for biodiversity conservation that varies with the type of habitat and their requirement. Protected areas are one of the prominent strategies for the in situ conservation of species and their habitats. However, this concept is not recent to India, and provisions for the establishment of reserved forests and laws such as the death penalty for killing elephants date back to the third century B.C. as mentioned in Kautilya's *Arthashastra* [2]. Many of today's existing national parks once served as a hunting preserve for the local Maharajas and Emperors during the colonial and precolonial era [3]. It was in 1936 when the Hailey (now Jim Corbett) National Park was formally notified as to the first national park of the country, and there were only four national parks till the 1970s (**Figure 1**). However, the continued hunting and habitat destruction resulted in a dramatic decrease in the population of tigers in the country. In the wake of this alarming decline of tigers, the then prime minister of India, Late Smt. Indira Gandhi, launched the "Project Tiger" in 1973, which still stands as the world's most comprehensive tiger conservation initiative. She established nine tiger reserves, hired guards to patrol them, and forcibly moved whole villages outside their perimeters. These efforts proved to be fruitful as the tiger numbers topped to 4,000 along with an increase in their prey, and thus, India had put forward a global model for wildlife conservation. Since then, the protected area network of the country increased exponentially after the 1980s, and presently there are about 104

Although these protected areas were initially established for biodiversity conservation, their objectives have now expanded to also include human-centered socioeconomic development.

Furthermore, major challenges to conservation and management of national parks are highlighted with suitable examples from Indian case studies (**Figure 2**).


**1. Mitochondria and DNA**

Mitochondria are double-membrane organelles that are found in the cytoplasm of most eukaryotic cells, and they are essential for the functioning of tissues that are highly dependent on aerobic metabolism, like the brain and heart, since they produce more than 90% of the energy needed for cellular functions [1]. The human mitochondrial genome (mtDNA) is a double circular molecule of 16,571 pairs of nucleotides (16.5 Kb) which contains 37 genes that code for 22 transfer RNAs, 2 ribosomal RNAs, and 13 subunits that encode mitochondrial DNA. These 13 subunits are key in the respiratory chain and in the oxidative phosphorylation system which contains 7 subunits of complex I, 1 subunit of complex III, 3 subunits of complex IV or cytochrome oxidase, and 2 subunits of complex V or ATP synthase (ATPase6 and ATPase8) (**Figure 1**) [1–3].

#### **1.1. Specific characteristics of mitochondrial genetics**

The type of inheritance of the mitochondrial genetic system, its location in a cytoplasmic organelle, and the continuous arrangement of genes with almost no intermediate nucleotides or introns and polyplasmy (high number of copies in each cell) provide genetic characteristics that clearly differentiate them from those of nuclear DNA. Each cell contains between 1000 and 10,000 copies of mtDNA depending on the tissue, surpassing a few hundred in the sperm and up to 100,000 in the oocyte [4]. Each mitochondrion contains between 2 and 10 molecules. The mtDNA is primarily maternally inherited by a vertical non-Mendelian pattern. Very small amounts of parental mtDNA have been detected; for example, a case of a 28-year-old male with mitochondrial myopathy was reported due to a new 2 bp deletion in the mtDNA of the ND2 gene (also known as MTND2), which encodes a subunit of the complex I enzyme of the mitochondrial respiratory chain. In this study, it was determined that

the mtDNA harboring the mutation was of paternal origin and was calculated to be present

The general pattern is that mothers transmit their mitochondrial genome to all of their offspring, but only daughters will pass it on to all of the members of the next generation. This is due to the high number of mtDNA molecules that exist in the ovules (between 100,000 and 200,000 copies) compared to a few hundred in the sperm. In addition, paternal mitochondria

The phenotype of a cell line can vary during cell division because the mitochondria are randomly distributed among daughter cells; so, if in a cell two populations of mtDNA coexist, one normal and one mutated (heteroplasmy), throughout divisions three different genotypes may originate: homoplasmic for normal mitochondrial DNA, homoplasmic for mutated mitochondrial DNA, and heteroplasmic DNA. Therefore, the phenotype of a cell with heteroplasmy will depend on the percentage of mutated DNA it contains. If the number of damaged mtDNA molecules is relatively low, complementation with normal DNA molecules occurs, and the genetic defect will not manifest [8]. When the mutated DNA exceeds a certain threshold, a pathogenic phenotype will develop according to a threshold effect: if ATP production is below the minimum necessary for the functioning of the tissues, due to defective proteins encoded in the mtDNA, illness might develop [7, 9, 10]. The number of DNA molecules is different in each organ and tissue depending on the required energy amounts for functioning. Therefore, the most affected organs and systems are vision, the central nervous system, skeletal muscle, heart, pancreatic islets, kidney, and liver (**Figure 3**) [6, 11, 12].

energy stored in the covalent bonds between ATP phosphates. This last form of potential chemical energy is easily usable by the cell and has been selected throughout evolution as the mechanism by means of which all cellular processes that require the use of energy readily dispose of it [10, 17]. The body must maintain a balance between the needs of cells and the availability of fuel, which is called metabolic homeostasis. The constant availability of fuel in the blood is called caloric homeostasis, whereby the blood level of fuel (in ATP equivalents) does not decrease below certain limits regardless of whether the individual is in a state of good nutrition or fasting. The maintenance of metabolic homeostasis is achieved through the integration of three main factors: (1) the concentration of nutrients in the blood, which affects the speed with which these are used and stored in different tissues, (2) hormone levels in blood (first messengers) that transmit information to specific tissues on the state of the organism and the contribution or demand of nutrients, and (3) the central nervous system (CNS) that by way of neural signals controls the metabolism directly or through the release of hormones [9, 18]. Despite its essential role in the energy metabolism of the brain and other tissues, the amount of circulating glucose is limited. To ensure its continued provision, the body stores metabolic fuels to provide glucose or energy in case of need. Within the homeostatic mechanisms that allow regulation of the availability of combustible molecules, hormonal control is one of the most important. Insulin and glucagon are the main hormones that regulate the storage and use of fuels. Insulin is an anabolic hormone that promotes the storage, while glucagon is the hormone that stimulates the mobilization of the combustible molecules [17, 18]. Other hormones, such as adrenaline, are released as a CNS response to hypoglycemia, exercise, and other types of physiological stress. Along with other stress hormones (glucocorticoids), adrenaline increases the availability of fuels. One of the requirements to maintain and perpetuate life is the preservation of homeostasis, that is, the constancy of the internal environment (blood levels of ions, lipids, and carbohydrates) within narrow limits. These conditions must be maintained even in varied situations such as rest, exercise, satiety, or fasting. How is our body harmonized to survive in different metabolic situations? In mammals, the coordination of metabolism is achieved through the neuroendocrine system. The main hormones involved in the regulation of intermediate metabolism are insulin, glucagon,

The brain must generate large amounts of ATP to maintain the membrane potential, which is essential for the transmission of nerve impulses. Under normal conditions the brain only uses glucose as fuel, oxidizing it through aerobic glycolysis. It does not use fatty acids. In fact, 60% of the total glucose consumed by the body is used by the brain. The metabolism of the brain is totally aerobic, consuming 20% of the total oxygen consumed by the body. It does not have appreciable reserves of glycogen or other fuels so it requires the constant supply of oxygen

Practically, until adulthood, we are well protected against damage to mitochondria since the body is able to produce antioxidant systems that defend us from it [23]. But as we get older, changes occur inside our cells that determine the progressive destruction of mitochondria
