Short-term gut microorganism dynamics induced by gumnivorous feeding for lesser slow loris
Lessor slow lorises (Nycticebus pygmaeus) naturally ingest plant gum as a main food. However, it is not popular to feed plant gum for slow lorises in captive environments such as zoos. In this study, we fed plant gum continuously for two lesser slow lorises reared in Japan Monkey Centre, which have rarely eaten plant gum. We assess the effect by analyzing the change of their gut microbiota from the viewpoint of animal welfare and feeding enrichment. Plant gum is composed of low degradable polysaccharide. Therefore, slow lorises may depend on gut microbiota for digestion of plant gum.
We collected their feces before and after feeding gum arabic for one month, respectively. We amplified the V1-V2 region of the bacterial 16S rRNA using universal primers by PCR and massively sequenced by an Illumina Miseq. Sequenced data is analyzed by the Qiime and R platform. We found that the microbiota structure is quite changed drastically after two days from starting feeding gum, which is the same as their detention time. Especially, the most drastic changed happened in Prevotellaceae. Some taxa had decreased or complementarily increased and some had vanished. We will analyze the functional aspect of these taxa by cultivation.

Measuring habitat preferences of African elephants in Kibale National Park, Uganda
Kibale National Park (KNP) in the Republic of Uganda is a humid evergreen rainforest between tropical rainforest and savanna, where diverse vegetation such as primary forest, secondary forest and grassland are mixed (795 km2). Originally savannah elephants have been distributed in this area, but forest elephants has been migrated from neighboring Democratic Republic of Congo (DRC) in recent years. As a result, the elephant population density in the park has increased by 354% from 2001 to 2003.
This migration has resulted in recent genetic analyses that document the hybridization between savanna elephant (Loxodonta Africana) and forest elephant (L. cyclotis) in this area. Despite recent interest in the elephants of KNP, little is known about elephant ranging patterns and behavior. A better understanding of elephant behavior is needed to more effectively deal with human-elephant conflicts, as well as promote the elephant conservation. This study focuses on quantifying elephant habitat preference in KNP. At this seminar I will present the results so far and future plans.

Psychology of animal groups: when and how collective intelligence emerges from individual cognition
For over a century, researchers have been investigating collective cognition, in which a group of individuals together processes information and acts as a single cognitive unit. However, we still know little about the circumstances under which groups achieve better (or worse) decisions than individuals. To address this question my research applies concepts and methods from psychology to both individuals and groups in order to directly compare their cognitive abilities. As model systems I use house-hunting by the ant Temnothorax rugatulus, and navigation by the homing pigeon, Columba livia. My work has shown that 1) rational group decisions can emerge from interactions among irrational individuals, 2) groups can process more information and thus are less prone to cognitive overload than individuals, and 3) groups show more precise discrimination than individuals, but individuals make better decisions than groups for easy discrimination tasks. Furthermore, my recent research has shown, for the first time in a non-human species, that group decisions are influenced by past experiences and improve progressively, a phenomenon known as cumulative cultural evolution. By combining empirical data and models I elucidate the emergent processes of collective cognition and suggest how and when groups (fail to) achieve higher cognitive performance than individuals.

Roles of faculty of forestry in human resource development for conservation in Laos
The education in Laos is considered as rapid progress since the 1980s. However, there are several challenges for Lao government to ensure a standard and quality of education are accessible for its population, especially for rural ethnic communities. The faculty of forestry (FOF) plays important roles to provide formal and informal educations and trainings related to forest management and conservation in Laos. Natural forests are the most important for national social-economic development and supporting the local people livelihoods as well as maintaining environment in Laos. During the mid of 19th century, wildlife and their habitats were widely destructed due to variety of reasons, in particularly the infrastructure and energy development. The forest conservation has been promulgate by the government through policies, laws and regulations. However, human resource development is necessary and required as a first priority. The FoF has been assigned not only in providing long term and short term education but also pursuing for scientific research. Further international collaboration and action are required to full fill this assignment.

これまでの研究内容と今後の研究について
卒業研究ではチーター（Acinonyx jubatus）を対象として多摩動物公園でマーキング行動の観察を行なった。放飼場では雌雄ともに高頻度でマーキング行動と匂いに関連する行動が観察され，これらがチーターの社会行動の中で主要な位置を占めることが示唆された。多くのマーキング行動の出現頻度や分布には雌雄差が認められ，その機能が異なる傾向があると考えられた。修士では卒業研究で得られた結果をもとにさらなるデータの蓄積やホルモン分析との比較によってマーキング行動とその機能を明らかにしていきたい。

ニホンリスの相対密度推定とクビワオオコウモリの遺伝的多様性解析
卒業課題研究では、カメラトラップと食痕を用いたニホンリスの相対密度推定手法を開発した。これらの手法を用い、京都市の大文字山及び音羽山にて相対密度推定を行った。修士課程では、クビワオオコウモリの遺伝的多様性解析を行う。クビワオオコウモリは5亜種に分けられており、そのうちの2亜種は絶滅危惧ⅠA類(CR)に指定されている。しかし、種内の遺伝解析に必要な多型性の高いマーカーは開発されていない。そこで本研究では、クビワオオコウモリのマイクロサテライトマーカーを開発し、解析を行うことにより、その遺伝的多様性や近交弱勢の有無、各島の個体群間の遺伝的分化と遺伝子流動について調べる。

Relative population density estimation of the Japanese squirrel and genetic diversity analysis of the Ryukyu flying fox
In my graduation research, I developed two methods for estimating relative population density of the Japanese squirrel using the camera trap and the food remains methods. By using these methods, I estimated the relative population density at Mt. Daimonji and Mt. Otowa, Kyoto City. In my master course, I am going to analyze genetic diversity of the Ryukyu flying fox. The Ryukyu flying fox is divided into 5 subspecies, and 2 of them are regarded as Critically Endangered. However, there is no highly polymorphic genetic marker for the Ryukyu flying fox. Therefore, I am going to develop microsatellite markers for them. By using the markers, I will investigate their genetic diversity, genetic differentiation and gene flow between each island, and inbreeding depression.

ddRAD-seq を用いた対州馬の遺伝浸透と遺伝的多様性の検証 -在来家畜保全にddRAD-seq を利用する-
経済性、生産性に重きをおいて進められた家畜の単一品種化により、在来の家畜の品種数・個体数は急激に減少し、さらに前述の単一品種と在来家畜の無計画な交雑（遺伝子浸透）も進んでおり、在来家畜の貴重な遺伝資源は失われつつある。在来家畜の遺伝資源を保持する上で、交雑してしまった品種を如何に戻すのかは重要な課題である。多くの在来家畜はすでに遺伝的多様性が低い状態にあるため、交雑の可能性がある個体をすべて除くと品種の絶滅につながる。この問題を解決するためには、在来家畜本来の変異を維持しながら、浸透した変異を取り除く交配計画が必要であり、そのためには高解像度なマーカーにより、浸透した変異と在来家畜本来の変異を区別することが不可欠である。そこで、私たちは、近年遺伝子浸透を経験した日本在来家畜「対州馬」に対して、ddRAD-seqにより得られたゲノムワイドなSNPマーカーを用いた遺伝子浸透および遺伝的多様性の検証を行い、その有用性を確かめた。ddRAD-seqによって得られたマーカーは、対州馬を含む日本在来馬5種と遺伝子浸透品種であるアングロアラブを明瞭に区別した。対州馬の全染色体中2つの染色体に遺伝子浸透の痕跡が検出されたが、その位置がゲノム上で離れていることから近年の浸透によるものではない可能性が高いことがわかった。一方で、対州馬の遺伝的多様性は他の日本在来馬に比べて低くなっており、対州馬における喫緊の課題は遺伝子浸透ではなく遺伝的多様性の低さにあることが明らかになった。近年の遺伝子浸透の痕跡はほぼ見つからなかったにもかかわらず、対州馬とアングロアラブの共有SNPsが多数検出されており、このことは単純なSNPsの共有のみで遺伝子浸透を評価することの危険性を示唆した。本研究の結果は、在来家畜における遺伝子浸透の過大・過小評価を避けるために、ddRAD-seqなどによるゲノムワイドなSNPマーカーを用いた集団遺伝学的な手法が不可欠であることを示している。

Unplanned crossbreedings between a native livestock and specific production breeds is one of the main reasons for the loss of valuable genetic resources in the native livestock. To avoid further loss of these resources, introgressed individuals should be identified for removal. In general, when the genetic diversity of a native livestock has already decreased, the removal of introgressed individuals from a population can put them on the brink of extinction. To solve this problem, high-resolution markers are needed to distinguish between introgression and native variation. Here, we applied ddRAD-Seq markers to analyze variation in a native Japanese equine breed, “Taishu,” which has undergone recent genetic introgression. Genome-wide ddRAD-Seq markers could distinguish the five breeds of native Japanese and Anglo-Arabian horses from their introgressed breeds. In the Taishu we found the signature of genetic introgression in only two chromosomes, but the signatures were separated in their genome, suggesting that the introgression might not be recent. The genetic diversity in the Taishu population was less than that in the other Japanese breeds, and the reduction in genetic diversity rather than genetic introgression is the most pressing issue. Although a few signatures of recent introgression were detected, a lot of shared SNPs (10% of all SNPs in Taishu) were detected between the Taishu and the Anglo-Arabian breeds. To avoid misestimations in the identification and estimation of the degree of introgression in native livestock, information on shared SNPs along with population genetics approaches based on the use of genome-wide markers, like ddRAD-Seq, is required.

Introduction of my previous feral cat study and plan for the master study
Last year, I researched on the diet of feral cats (Felis silvestris catus) in Tokunoshima Island, Japan. Our study revealed that even cats captured in forests depended on the artificial resources. This result strongly suggests the “hyperpredation” by human feeding, which means that feeding by humans sustains feral cat populations and indirectly facilitating the decrease of endemic mammals.
For my master study, I will start the research on the domestic horse (Equus caballus). I have two plans, one is the genomic study on feral horses in Serra D’Arga Portugal, and the other is the cognitive/psychological study on captive horses. I would introduce both in the next seminar.

Temporal patterns of bird roadkills in southern Portugal
Despite collision with vehicles being a big source of mortality for many bird species worldwide, very little attention has been given to its temporal trends. We assessed how the roadkill mortality patterns of common bird species changed over a period of nine years in southern Portugal and which weather factors influence the observed patterns. We corrected mortality estimations and fitted GAMM models to all species. Roadkills’ numbers increased substantially after correcting for survey frequency, and carcass persistence and detectability. Our results show that, overall, mortality decreased over time and was generally higher during spring and summer months. The lack of a clear relationship between the weather variables and the observed mortality patterns suggests the existence of additional factors important to explain the observed trends. This study provides concrete data that mortality due to car collisions may change overtime, which can have demographical consequences and risk the effectiveness of mitigation measures, highlighting the need to further address large temporal scales in research. For my PhD at WRC, I wish to research feral horses’ (Equus caballus) social behavior and structure. The study of feral horses gives valuable insight into the behavior of pre-historic horses and allows for a better understanding of the instinctive and learned behaviors that drive domestic horses, as well as the cognitive capabilities of this species. Horse groups with single and multiple stallions occur simultaneously throughout the world in different feral horses’ populations. However, little is known on why bands with multiple stallions and bands with only one stallion exist.Thus, I intend to explore the origin and differences between multi and single-stallion bands in horse societies, to better understand how multi-stallion groups are formed, how they operate and assess group stability.

野生アジアゾウの集団移動
動物の集団が移動するとき、特定の個体が移動方向と開始のタイミングを決め他のメンバーが従う場合(unshared decision)と、複数の個体が意思を示し合わせることで決定する場合(shared decision)がある。アジアゾウは離合集散性が高く、集団の構成員は一定でない。寿命は約60年と長く、他の哺乳類よりも並外れた記憶容量を持つ。知識もしくは経験量が年齢とともに増えると仮定すると、集団内の各個体が持つ知識にはばらつきがあると考えられる。そのような特性を持つ集団が移動するとき、最も知識のある個体が集団を先導すると予測される。
発表者はスリランカのウダワラウェ国立公園の水場を集団で訪れるゾウのビデオ観察を行った。各イベントにおいて(i)水場に最初に到着した個体、(ii)水場から出発する際に出発方向へ体を向けた個体、(iii)最初に出発方向へ移動をし始めた個体を記録した。
(i)~(iii)が同じ個体によって行われたイベントは30%(8/27)であり、常に特定の個体が集団を先導しているわけではないことが示唆された。
今後は、集団の移動方向およびタイミングが決定される際にどのような要因（出発し始める個体の特性や移動速度、群れのまとまり具合、集団構成）が効いているのかを明らかにすべく、取得したビデオデータの分析を進めていく。

水中遊泳者への探索行動と遊泳隊列の性・成長段階差
沿岸定住性のミナミハンドウイルカは、限られた環境の中で個体群を持続している。発表者は、水中での直接観察から野生イルカの探索傾向と集団内の遊泳隊列の性・成長段階差を明らかにした。結果、メスの探索傾向の強さと、オスがメスを追いかけるような特徴的な遊泳位置関係が明らかになり、これらは資源獲得や繁殖成功につながる重要な特徴であることが示唆される。本セミナーではこれらの結果と、在学中に関わった研究として、熊本のスナメリの採餌行動や集団形成についても紹介する。

Difference by sex and age class: inquiring behavior and swimming order
Indo-Pacific bottlenose dolphins is philopatry and keep the population in the limited environment. I observed the dolphin behavior directly underwater, so that I clarified the differences the inquisitive characteristics and swimming position in the group by sex and age class. In the results, females might be more inquisitive than males and males tended to follow females, especially adult females. These results showed the important characteristic for gaining the resource and successful breeding. I will talk about that mainly, I talk also feeding behavior and the huge group in finless porpoise as ongoing study.

御蔵島に生息するミナミハンドウイルカの夜間生態
伊豆諸島御蔵島周辺海域には、ミナミハンドウイルカ(Tursiops aduncus）の定住個体群が存在する。本個体群においては、長期的な個体識別データを基に社会行動や社会構造など、日中の行動や生態に関する研究が多く行われてきた。その一方で、夜間生態については目視調査が難しいことなどから、これまでにほとんど研究が行われておらず、夜間も島の周辺に生息している可能性が高いことが示唆されているのみである（Morisaka et al., 2015）。そこで本研究では、本種の夜間生態の一端を明らかにすることを目的に、音声録音調査を行った。
2015年6月と8月に1日ずつ、定点型受動式録音装置（AUSOMS-micro）を御蔵島周辺海中に設置し、24時間の連続録音を行った。設置地点は、日中にイルカがよく観察される海岸線から約200 mまでの範囲の、水深10～15 mの4地点である。記録された音声を、ホイッスル、クリックス、その他の音声に分類し、時間帯や場所による比較を行った。
総録音時間は194時間で、4地点すべてにおいてホイッスルとクリックスが記録された。明期と暗期で録音された音声の発声頻度に差はなく、夜も昼と同様に島周辺にいると考えられた。また、場所による発声時間帯に違いがあったほか、同じ地点でも日によって発声時間帯が異なった。さらに滞在時間が極端に短く、通過しているのみと考えられる地点があり、同じ島周りでも利用の仕方が異なる可能性が考えられた。

Nighttime distribution and behavior of Indo-Pacific bottlenose dolphin around Mikura Island
Indo-Pacific bottlenose dolphin (Tursiops aduncus) population inhabit coastal areas around Mikura Island in the Izu Island Chain. Study about social behavior and social relationship of the population in the daytime have studied a lot. But there is few study about nighttime activity, because it is difficult to observe them in the dark. In this study, I studied the distribution and behavior of the population by recording the sound of underwater for 24 consecutive hours. I put a hydrophone in 4 points around the Island in June and August 2015. The total recording time was 194 hours, whistle and clicks were recorded at all four points. There was no difference in the vocalization frequency of the sound recorded in the daytime and the nighttime. Also, there were differences in vocalization frequency by time of day depending on places, and vocalization frequency varied from day to day even at the same spot. Furthermore, the sojourn time was extremely short, there were points considered to be passing only, and it was thought that the habitat use might be different even around the same island.

動物園の熱帯産ヘビ類3種間における摂水行動の比較
摂水行動は、動物の形態や体内環境、餌、周囲の環境など様々な要因に影響され得る。したがって、摂水はその種の環境への適応を反映した行動の一つであると言え、これを調べることでその基礎生態の重要な一部分を知ることができると考えられる。加えて、これを知ることで飼育環境の改善も期待できる。
ヘビ類では一般に摂餌の頻度が低くても生きていける種が多く、大型の種などは数週間から数か月の絶食にも耐えられることが知られているが、摂水に関しての知見は少なく、その頻度や水場の利用といった基本的な摂水行動は未知の部分が多い。そこで、京都市動物園熱帯動物館において飼育されているボア科2種およびニシキヘビ科１種のヘビの摂水行動を3週間撮影し、映像から各種の摂水様式を調査するとともに種間での比較を行った。

A comparison of drinking behavior among three tropical snake species
Drinking behavior is affected by various factors such as forms, diets, and internal or external environment. Therefore, we can say drinking behavior reflects a species’ adaptation to the environment, and researching this behavior can lead to knowledge about an important part of the ecology of the species. Furthermore, rearing environment can be improved by it.
Generally, most of snakes don’t need frequent feeding, and some species can live without feeding for several weeks to a few months, but less is known about drinking behavior and its frequency. Then, I took the videos of three tropical snake species around the water stations in Kyoto City Zoo for three weeks and compared their drinking behavior.

Cooperative management and operation of national parks: The cases in Kinki region
Japan has adopted a Regional Natural Park System that designates national park land as such regardless of private land ownership. It means that national park areas include the place for life and industry, and therefore there are many stakeholders. From the above, national parks in Japan need to be managed while taking into account the lifestyles of local residents and relevant industry conditions, on the other hand, their local activities have contributed directly or indirectly to the promotion of national park protection and usage.
Based on my experience in Kinki Regional Environment Office, I will introduce how we are dealing with management of national parks in terms of collaboration with various regional parties, and suggest what are needed and important for effective management.
We will have Asura international seminar (Dr. Oliver Ryder) from 10:00 at the same venue. We would be happy if you join us.

Verification of the effectiveness of environmental enrichment and the visitor effect in captive tigers
Zoo animals are often kept in environments that are significantly different from the original habitat and as a result, stereotypic behaviors such as walking in the same route in the field may be occurred. Environmental enrichment is device for improving the welfare of zoo animals and is considered important for decreasing stereotypic behavior. It is thought that stereotypic behavior involves multiple factors such as the existence of environmental enrichment and the influence of visitors, but no complex study has been done. In this study, I observed the Amur tigers in Kyoto City Zoo, and examined the effectiveness of environmental enrichment and the factors that influence behavior of tigers.

Spatial positioning of individuals in feral horses
Various animals form groups to benefit from several perspectives. There is
also diversity in membership forming the group. However, spatial positioning of
individuals is the universal issue in animal group. Theoretical studies have
predicted the importance to individuals’ condition, feeding efficiency and
transferring information between individuals. Although empirical studies have
also suggested the importance, there are still necessity to discuss and
fragility regarding on quantitativity. Investigation focusing on species living
in two dimension is especially difficult because it is mostly impossible to take
high quality data excepting some good combination of situations. I used a
drone to take pictures of horses group from the sky to reveal basic
characteristics of spatial positioning in a group of feral horses. in Serra
D’Arga, Portugal. Horses live in plain area on the top of mountain. Therefore,
this combination, drone and horses, is very suitable to tackle this problem.
Results showed that each individual have personal space within three body length
and nearest neighborhood were located right and left side. In addition, social
network analysis was conducted in affiliative network and inter-individual
distance network, because horses have high sociality. The result showed there is
no correlation between those two networks, which might suggest that horses have
complexity in their society that cannot be simply described with affiliative
relationships between individuals.

Sex differences of giraffe in shade use and feeding posture during the dry season in Katavi National Park, Tanzania
Many giraffes live in savanna. Most of the savanna environment is sunny, and
there are a few shade places where tall trees exist. How do giraffe use sunny
and shade places? In order to investigate the sex differences of giraffe
behaviors, I observed adult giraffes during the dry season in 2016 and 2017 in
Katavi National Park, Tanzania. I found that males spent more time in the shade
than females, and they preferred feeding on large shade trees with their neck
stretched vertically upwards. They could ruminate and rest at same places under
the trees which they ate. Female giraffes mainly fed on shrubs under the sun,
and they sometimes went into the shade for rumination and taking a rest. The sex
difference in shade use might be related with the difference of body size and
feeding posture.
