It may be said that the history of Japanese zoo, aquarium and social education is characterized by lack of the independence of will. As for it, the establishment of the zoo as a leader of the natural science and scientific research has been disturbed. In the Meiji period, the scientific research has not been laid to the essence of the organization as for the zoo, the aquarium at the historical standing point in Japan. It was surrounded by various breaks to come from different motives and value standards although the legislative system based upon the freedom after the Second World War was maintained, and the development of the research in the zoo has been poor. The breaks have been present in the zoo as follows: break between duties and the research, break between pure science and practical technique, break between social education administration and the scientific research administration, break between the applied veterinary medicine and zoology, break between reductionism and comparative zoology, break between education administration and the environmental administration, and break between education administration and the construction administration. It is desired that zoo will be established as a leader of the scientific research.

The impact of environmental stimuli on the expression of nesting behaviour of Sulawesi babirusa (Babyrousa celebensis) was explored over a period of 1339 days from 01 August 2006 until 31 March 2010 in a large animal enclosure on Bali, Indonesia. We found that nest building behaviour and the re-use of sleeping nests occurred more frequently in the dry season than the wet season and was clearly influenced by both a drop in the ambient temperature and an increase in wind speed. Additionally, net effective temperature (NET) computed from a combination of ambient temperature, relative humidity, and wind speed indicated a close relation to the nesting behaviour frequency; a decreasing trend of the expression rate of nesting behaviour with increasing NET in the early evening. Moreover, the trend of the expression rate by 12-hr NET fluctuation from 05:00 hr to 17:00 hr was also found out in all seasons. Meanwhile, 24-hr rainfall had a negative impact on the expression rate. These findings suggested that NET was a useful meteorological index to discuss the motivation to exhibit the nesting behaviour of babirusa, and also babirusa probably found thermal comfort in the sleeping nest.
从2006年8月1日至2010年3月31日，在印度尼西亚巴厘岛的一个大型动物圈舍中，研究了环境刺激对苏拉威西巴比沙(Babyrousa celebensis)筑巢行为表达的影响。我们发现，筑巢行为和睡眠巢的再利用在旱季比在雨季发生得更频繁，并且明显受到环境温度下降和风速增加的影响。此外，由环境温度、相对湿度和风速组合计算的净有效温度(net)与筑巢行为频率密切相关;傍晚前期巢态表达率随NET的增加呈下降趋势。此外，还发现了各季节在05:00 ~ 17:00 hr间表达率随12 h NET波动的变化趋势。同时，24小时降雨对表达率有负向影响。这些发现表明，NET是一个有用的气象指标，可以用来讨论babirusa表现出筑巢行为的动机，babirusa可能在睡眠的巢中找到了热舒适。

In the face of escalation of biodiversity loss, ex-situ conservation challenges by zoos and aquariums are becoming more important. Since the available resources of zoos and aquariums such as facilities, human resources and financial resources are limited, collection plan which prioritize the target species based on the objectives or feasibility has been developed. And ex-situ conservation measures are carried out in accordance with the captive population management programs that have been set up for prioritized species to maintain proper genetic and demographic conditions of the populations. Furthermore, recently animal welfare practice must be considered to proceed with the conservation programs. What it comes down to is that zoos and aquariums are required to set up the captive populations consisting of physically and psychologically healthy individuals and maintain them for long periods of time with preserving their genetic diversities by implementing all these conservation approaches. To increase effectiveness of ex-situ conservation approaches, several supportive measures such as husbandry guidelines and accreditation systems for zoos and aquariums have been introduced. Public awareness activities and research studies have also been gaining recognition as the important components of conservation challenges by zoos and aquariums. As described, conservation challenges by zoos and aquariums are becoming diversified and complicated. Though these challenges are positioned as the supplementary measures for in-situ conservation, it is quite certain that they will become more important in the future.

To assess the genetic suitability of reinforcement of two populations of the Japanese brown frog (Rana japonica) in Yokohama City, we attempted to clarify their genetic relationship based on sequence variation of mitochondrial DNA control region and polymorphism of 10 microsatellite DNA loci. The results showed that these two populations are genetically related, though they are presently isolated. This appears to conform to the conditions for reinforcement of the two populations.

We adopt husbandry training for measurement of body weight and body temperature, and blood collection into many animal species as the rearing management at Omuta city zoo. Adopting husbandry training, it has enabled, by only behavioral restraint, the medical examination and examination of the primates and big cats without the mechanical and chemical restraints. Hematological and biochemical values were shared with an another zoo. So that we made good use of health control by stored data. Some animals were incorporated in sperm collection. Therefore, husbandry training has possibility to contribute to the breeding of zoo animals. If regular blood collection is possible by husbandry training, we are able to understand the blood kinetics of drags. So that, it may contribute to the development of the veterinary care of zoo animals. Taking in husbandry training, it could increase to get many knowledges. If we cooperate with research institutes based on these knowledges, the study and veterinary care of zoos will be developed.
