<p>Bali Myna (Leucopsar rothschildi) is Bali’s endemic bird. Their number is decreasing gradually in the wild (Balen et al., 2000). Its bright color of white feather and blue skin that surrounded its eye have made them easy to be hunted when it perched on abranch. Bali Myna was classified as endangered species by International Union of Conservation and Natural resources (IUCN) in 1977 (Whitten et al. 1999). There is a captive breeding in Tegal Bunder, Bali Barat National Park (BBNP) called Bali Myna Guidance Centre to increase wild population as an effort to prevent extinction. There, its conditions should be monitored regularly to keep them in prime condition, before being released for breeding purpose. Their condition could be controlled by monitoring their daily activities.</p>

In The Wild

A recent complete assessment of the conservation status of 5487 mammal species demonstrated that at least one-fifth are at risk of extinction in the wild. We retrospectively identified genuine changes in extinction risk for mammals between 1996 and 2008 to calculate changes in the International Union for Conservation of Nature (IUCN) Red List Index (RLI). Species-level trends in the conservation status of mammalian diversity reveal that extinction risk in large-bodied species is increasing, and that the rate of deterioration has been most accelerated in the Indomalayan and Australasian realms. Expanding agriculture and hunting have been the main drivers of increased extinction risk in mammals. Site-based protection and management, legislation, and captive-breeding and reintroduction programmes have led to improvements in 24 species. We contextualize these changes, and explain why both deteriorations and improvements may be under-reported. Although this study highlights where conservation actions are leading to improvements, it fails to account for instances where conservation has prevented further deteriorations in the status of the world's mammals. The continued utility of the RLI is dependent on sustained investment to ensure repeated assessments of mammals over time and to facilitate future calculations of the RLI and measurement against global targets.

Tarsier (Cephalopachus bancanus borneanus) is one of the endemic primates in Kalimantan. IUCN (International Union for the Conservation of Nature and Natural Resources) has established the conservation status of Cephalopachus bancanus borneanus as a vulnerable primate. This research was conducted in the Punggualas area, Sebangau National Park, from June to August 2019. The data collected was the number and distribution of tarsier population along with the composition and structure of vegetation. This study revealed that tarsiers in Punggualas have a tendency to live solitary. A total of 6 tarsier individuals were found in an area of ??4 km2, with a total length of 22 km of transects. The population in the scope of the study area is 23 individuals who occupy an area of ??4 km2 with a population density of 5,682 individuals / km2. The density of vegetation in Punggualas reaches 1179 individuals per hectare at the sapling level, where this area is a suitable habitat for shelter, locomoting, and as sleeping site for Tarsiers.

Abstract Choeropsis liberiensis (Morton, 1849), commonly called the pygmy hippopotamus or pygmy hippo, is the only extant species in the genus Choeropsis. A solitary, forest-dwelling ungulate endemic to the Upper Guinean forest ecosystem in West Africa, it is classified as “Endangered” by the International Union for Conservation of Nature and Natural Resources and is a Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) Appendix II species. The smaller of the two extant hippopotamids, it is relatively uncommon in zoological facilities and private collections worldwide.

The red wolf (Canis rufus) inhabited the Southeastern United States until the early 1900's when aggressive hunting and a shrinking primitive habitat virtually eradicated the species. C. rufus was certified as an endangered species in 1967 and was essentially extinct in the wild by 1980. About 200 animals are preserved in zoos and captive breeding facilities where efforts are underway to increase the stock. Since a shrinking gene pool and captive stress may reduce reproductive vigor, we undertook an electron microscopic examination of red wolf semen used for artificial insemination at the Graham, WA breeding facility of the Point Defiance Zoo.Animals were anesthetized with 175 mg. Telazol, IM before electroejaculation using a rectal probe Semen was washed in PBS prior to fixation in 1.25% glutaraldehyde in 0.1 M cacodylate, post fixed in OsO4, dehydrated in alcohol and propylene oxide and embedded in Epon 812. Some samples were incubated in capacitation or maintenance media for several hours before fixation as above.

Behavioural Approaches to Conservation in the Wild is based on a series of papers from a symposium entitled "Conservation and Behaviour in the Wild" held during the Animal Behaviour Society annual meetings in Lincoln, Nebraska in 1995. The book was compiled because the editors (and others) felt that both behavioural researchers and conservation biologists did not adequately recognize the important role that behavioural studies could play in conservation efforts. Traditionally, behavioural researchers have limited the conservation applications of their research to captive breeding and reintroduction programmes of endangered species, while conservation biologists have focussed on landscape design and ecosystem restoration without necessarily considering animal behaviour. The objectives of the book are twofold: to stimulate behavioural researchers to think about how their work can contribute to conservation of biological diversity, and to show conservation biologists the relevance of behavioural research in solving conservation problems. As expected given the location of the symposium and the high proportion of northern hemisphere contributors, most examples presented are from that region.

Mature Seeds

Symplocarpus nipponicus, a member of the Araceae family, is an endangered plant in several prefectures in Japan. For the conservation of this wild species, we investigated the morphology, life cycle, and genetic diversity of three wild populations. By fixed-point observation over several years, we found that it takes at least four years for the plant to set the inflorescences consisting of spadices and spathes, and another two years for it to set mature seeds. To examine the genetic diversity in the wild population, we developed 11 novel microsatellite markers and investigated the genetic variation in three populations in Kyoto Prefecture: Ayabe, Hanase, and Momoi. The Ayabe population carried less genetic variation than the other two areas, suggesting the isolation of the habitat and thus a higher risk of extinction. Our results provide basic knowledge of the ecological aspects of S. nipponicus, as well as molecular techniques for the assessment of its genetic diversity, and thus are useful for the conservation of this endangered species.

Abstract Supplementation programs, which release captive-born individuals into the wild, are commonly used to demographically bolster declining populations. In order to evaluate the effectiveness of these programs, the reproductive success of captive-born individuals released into the wild is often compared to the reproductive success of wild-born individuals in the recipient population (relative reproductive success, RRS). However, if there are heritable reductions in fitness associated with captive breeding, gene flow from captive-born individuals into the wild population can reduce the fitness of the wild population. Here, we show that when captive ancestry in the wild population reduces mean population fitness, estimates of RRS are upwardly biased, meaning that the relative fitness of captive-born individuals is over-estimated. Furthermore, the magnitude of this bias increases with the length of time that a supplementation program has been releasing captive-born individuals. This phenomenon has long-term conservation impacts since management decisions regarding the design of a supplementation program and the number of individuals to release can be based, at least in part, on RRS estimates. Therefore, we urge caution in the interpretation of relative fitness measures when the captive ancestry of the wild population cannot be precisely measured.

Indochina War

Systematic efforts to conserve Viet Nam's natural resources began (in the North) in the early 1960s with the establishment of a 25,000-hectares' area, Cue Phuong National Park, south-west of Hanoi. Since the end of the Second Indochina war, Viet Nam's Ministry of Forestry has undertaken a comprehensive programme to restore forests that were destroyed or damaged in the fighting, to inventory forests and their resources, and to develop forest management for the economy and recreation of the Vietnamese people. The Ministry of Forestry's Institute of Forest Inventory and Planning is the agency carrying out these tasks; it employs about 5,000 people, including well-trained scientists.Before 1963, there were no regulations regarding hunting in Viet Nam. Now the Ministry of Forestry has a Department of Protection which attempts to regulate hunting of game, such as deer, Wild Pigs, Tigers, and Leopards. Many species of birds and mammals are now totally protected. These include two primates, the Indochina Gibbon and the Douc Langur, as well as three species of wild cattle, the Kouprey, Banteng, and Gaur. The Kouprey and the Javan Rhinoceros are classified as endangered species because only a few individuals are known to be still alive, at least in Viet Nam. Elephants are trapped and trained for commercial purposes and for capture of wild Elephants, while the wild herds are increasing owing to the war's end and the prevention of killing.
