Critically endangered White-rumped vulture (WRV), Gyps bengalensis and Slender-billed vulture (SBV), Gyps tenuirostris monitoring was conducted in Nawalparasi district in the winter of 2005 following Postupalsky criterion. The objectives of this study were to identify and monitor nest localities, behaviour and to explore information about the vultures. A total of 48 Gyps vulture nest was located at six colonies. Of these nests, 18 were found to be active nets, six nests belonged to SBV and 12 nests belonged to WRV. Hundred percent nestling successes were observed in the study area. Restricted pesticides i.e. BHC and DDT were found used in this area. Diclofenac was the commonly used veterinary drug in the treatment of livestock. Carcasses disposal practice was found favorable to the vulture's survival. Gyps vulture richness found in this area is due to the availability of food i.e. floating carcass along the edge of the Narayani river and suitable habitat for roosting and nesting. The majority of the respondents had found favorable attitude towards vulture conservation. Further studies on Gyps vulture to identify the breeding status, head droppings behavior as well as conservation awareness program for local people and school children are recommended for long-term survival of these lords of the sky in the study area.

Vulture Conservation

SummaryConcerns for the long-term survival of vulture populations on the Indian Subcontinent, owing to widespread poisoning by the veterinary drug diclofenac, have led to increased conservation focus on South-East Asian countries where diclofenac is not used and relict populations of vultures occur. We document here how White-rumped, Slender-billed and Red-headed Vultures have declined substantially in abundance and contracted in range in Myanmar over the last 50 years. Using a vulture restaurant method we determined that the population of vultures in Myanmar is at least 136 individuals, made up of at least: 62 White-rumped Vultures, 21 Slender-billed Vultures, 51 Himalayan Vultures and two Red-headed Vultures. The decline in the resident Gyps species is most likely due to declines in wild ungulate populations. Our population estimates are provisional and the survey covered only a proportion of the possible vulture range within Myanmar. Himalayan Vultures were not recorded in Myanmar in historical times, and possible reasons for the recent upsurge in records are discussed. Myanmar presents an opportunity of global significance for vulture conservation, due to the persistence of three Critically Endangered vulture species in a country where diclofenac is not used.

Short Term Survival

SummaryCambodia supports populations of three Critically Endangered vulture species that are believed to have become isolated from the rest of the species’ global range. Until recently Cambodia’s vulture populations had remained stable. However a recent spike in the number of reports of the use of poisons in hunting practices suggests the need to re-evaluate the conservation situation in Cambodia. Population trend analysis showed that since 2010 populations of the White-rumped Vulture Gyps bengalensis and Red-headed Vulture Sarcogyps calvus have declined, while the Slender-billed Vulture Gyps tenuirostris may also have started to decline since 2013. These trends are supported by evidence of reduced nesting success. A survey of veterinary drug availability revealed that diclofenac, the non-steroid anti-inflammatory drug responsible for vulture declines in South Asia was not available for sale in any of the 74 pharmacies surveyed. However, a poisoned Slender-billed Vulture tested positive for carbofuran in toxicology tests. This provides the first evidence of a vulture mortality resulting from carbofuran in Cambodia. The findings suggest the urgent need to tackle use of carbamate pesticides in hunting. Proposed conservation actions are: a) prevention of poisoning through national bans on harmful carbamate pesticides and diclofenac and education campaigns to reduce demand and use; b) training of personnel in priority protected areas in detection and response to poisoning incidents; c) maintenance of a safe and reliable food source through vulture restaurants to ensure short-term survival, and d) protection and restoration of large areas of deciduous dipterocarp forests to enable long-term species recovery.

Grave Danger

Two species of vulture White-rumped Gyps bengalensis and Slender-billed G. tenuirostris are in grave danger of extinction with rapid decline throughout their ranges in Nepal with the complete loss of breeding colonies and local extinctions increasingly taking place. Nepal Government has already banned veterinary drug diclofenac which is the major cause of decline due to poisoning in food supply. Meloxicam has been widely promoted as the safe replacement of Diclofenac. Captive population have been established at Kasara, Chitwan National Park for future reintroduction. To reduce mortality in the wild in situ measures have been initiated through establishment of vulture restaurants as safe feeding sites.

The approach expressed by its author A. Kopčaj as a Spiral management is based on the philosophy according to which the firm is perceived as a living organism. Living organisms are guided by the principle of reducing their entropy in order to ensure the inevitable energy as well as their long-term survival. The contribution is analysing one of the potential applications of the above-indicated approach to the firm in which the measurement of the so-called internal entropy gives the possibility to determine in a very precise way whether the new managerial approach can be or cannot be implemented in the firm in the current state or whether it is possible to define the strategies for cultivation of the firm´s social capital. The paper proceeds from the data acquired during practical applications of the Spiral management in the environment of the Czech and Slovak companies. Key words: entropy, social subsystem of the firm, technical subsystem of the firm, the Spiral management.

Lowland Forests

Abstract From 1999 onwards, level, lowland forests (altitude < 150 m, slopes < 10°) in the Tanintharyi Region of southern Myanmar have been cleared on a large scale and replaced by oil palm plantations. This has resulted in a drastic decline in suitable habitat for several species, including Gurney's pitta Hydrornis gurneyi (Passeriformes, Pittidae). The habitat for this species has decreased by > 80%, leading to its categorization as Critically Endangered on the IUCN Red List in 2019. As threats in the region have continued, we updated information on the status of the species’ habitat in January 2020, and examined forest loss in the three strongholds where the species still persists in the wild. Since the previous estimate in 2017, suitable habitat in these locations has decreased by 8% (from 656 to 603 km2), with > 10% of the remaining area now in fragments of < 1 km2, which are unsuitable for the mid- to long-term survival of the species. Forest degradation and edge effects from increased fragmentation have led to further loss of suitable habitat in these strongholds. Projections indicate that unless conservation action is taken, all suitable habitat will disappear by 2080. The main threat to the long-term survival of Gurney's pitta is the lack of legal protection of primary lowland forests, resulting in uncontrolled clearance for small- and large-scale agriculture and industrial development. We provide recommendations to reduce the rate of loss of the remaining suitable habitat for the species.

AbstractThe creation of new populations through reintroductions in their former range is still necessary for the long-term conservation of the Iberian lynx (Lynx pardinus). A large-scale assessment of habitat suitability is a necessary prerequisite for evaluating the possibility of carrying out lynx reintroductions. We modelled habitat suitability for the Iberian lynx in the Iberian Peninsula using MaxEnt. Lynx presence data for 2010–2013 from Andujar-Cardeña and Doñana populations were used. Habitat variables were quantified using the CORINE Land Cover. This habitat suitability model predicted an environmentally suitable area of 87,747 km2, which represents 14.08% of the whole Iberian Peninsula. Of the total suitable habitat identified, 45% is located in a large continuous area in the south-western quadrant coinciding with the historical range of the species in the mid-20th century. However, there are also relevant patches mainly in the north-eastern quadrant. About 55% of the potential area suitable for the lynx falls outside protected areas. If Iberian lynx populations are to attain levels that will facilitate their long-term survival, it will be necessary to consider potential habitat for the species throughout the whole of the Iberian Peninsula.

General Climate

Giant pandas (Ailuropoda melanoleuca) are one of the most widely recognized endangered species globally. Habitat loss and fragmentation are the main threats, and climate change could significantly impact giant panda survival. We integrated giant panda habitat information with general climate models (GCMs) to predict future geographic distribution and fragmentation of giant panda habitat. Results support a major general prediction of climate change—a shift of habitats towards higher elevation and higher latitudes. Our models predict climate change could reduce giant panda habitat by nearly 60% over 70 years. New areas may become suitable outside the current geographic range but much of these areas is far from the current giant panda range and only 15% fall within the current protected area system. Long-term survival of giant pandas will require the creation of new protected areas that are likely to support suitable habitat even if the climate changes.

The fishing cat Prionailurus viverrinus is a wetland specialist endemic to South and Southeast Asia. Nepal represents the northern limit of its biogeographic range, but comprehensive information on fishing cat distribution in Nepal is lacking. We compiled fishing cat occurrence records (n=154) from Nepal, available in published literature and unpublished data (2009 – 2020), to assess their distribution. Bioclimatic and environmental variables associated with their occurrence were used to predict the potential fishing cat range using MaxEnt modeling. Fishing cat distribution was influenced by elevation, precipitation of the warmest quarter (18_bio), precipitation of the driest month (14_bio) and land cover. Wetlands and forest cover were the important predictors of fishing cat distribution. The model predicted an area of 4.4% (6,679 km2) of Nepal as potential habitat for the fishing cat. About two third of the predicted potentially suitable habitat lies outside protected areas, however a large part of the highly suitable habitat (67%) falls within protected areas. The predicted habitat map serves as a reference for future investigation into fishing cat distribution as well as formulating and implementing effective conservation programs for fishing cats in Nepal. Fishing cat conservation initiatives should include habitats both inside and outside the protected areas to ensure long-term survival. We recommend conservation of wetland sites, surveys of fishing cats in the identified potential habitats, and study of their genetic connectivity and population status.

Malaysia is a known source and consumer of bear bile products in Asia, and sun bears are persistently poached to meet the demand for traditional Chinese medicine (TCM). Surveys of TCM outlets in the East Malaysian states of Sabah and Sarawak were conducted in 2018 and 2019 as part of continuing efforts to monitor the availability of bear bile products in the country. Despite being illegal, the trade in bears and their parts persists, although with fewer TCM outlets offering such products in comparison to numbers reported in previous studies. In 2012, 42% of TCM outlets in Sabah and 35.4% in Sarawak were found to contain bear bile products. This has since dropped to 35% in Sabah and 19.3% in Sarawak in 2018-2019. Gall bladders were the main type of commodity for sale in both states, and were reportedly sourced predominantly by indigenous people. It was evident that most retailers surveyed were aware that the trade in bears and their parts was strictly prohibited, and some traders claim to have stopped selling illegal bear products for this reason. However, some traders who continue to trade in these illegal commodities have become more discreet. These factors contribute to the reduction in TCM outlets observed selling bear bile products. This reduction may also be due to diminishing sun bear populations, as some traders have claimed to have stopped selling bear bile products because of the rarity of or difficulty in procuring genuine bear gall bladders. The threat of illegal trade, combined with loss and degradation of suitable habitat and food resources as well as conflict with humans, puts sun bears at considerable risk. Efforts to mitigate these threats are urgently needed. Reduction of demand for bear parts is essential, as is stronger legal protection, enhanced enforcement and increased community involvement in bear conservation actions to ensure the long-term survival of viable bear populations in Asia.

Pro Inflammatory Cytokines

The ability of metazoan cells to undergo programmed cell death is vital to both the precise development and long-term survival of the mature adult. Cell deaths that result from engagement of this programme end in apoptosis, the ordered dismantling of the cell that results in its 'silent' demise, in which packaged cell fragments are removed by phagocytosis. This co-ordinated demise is mediated by members of a family of cysteine proteases known as caspases, whose activation follows characteristic apoptotic stimuli, and whose substrates include many proteins, the limited cleavage of which causes the characteristic morphology of apoptosis. In vertebrates, a subset of caspases has evolved to participate in the activation of pro-inflammatory cytokines, and thus members of the caspase family participate in one of two very distinct intracellular signalling pathways.
