本人於2014 年 3 月 14 日至 18 日至日本廣島參加第 61 屆日本生態學會會議。我邀請三 位來自美國、紐西蘭、及日本的學者，聯合主講「Invitation to body size-based community ecology」。這個主題被大會視為最重要的主題，並被安排在 S1 場次。這項主題主要介紹傳統基 於物種的生態研究，忽略個體發生成長而引起的群聚動態，所導致的嚴重問題。此外，我也受邀 參與另一項主題「sex and community ecology」的討論並給予評價。與會過程中，我充分的和 所有講者進行討論並分享未來研究方向。我確信這次會議行程除了讓我獲益良多外，更將促進台 日學者間更緊密的交流。(229 字)
Abstract
I have visited Hiroshima, Japan for 2014 March 14th to 204 March 19th to attend the 61th annual
Meeting of Ecological Society of Japan. At the meeting, I organized a special, international symposium, where I invited three foreign speakers Drs. Andre de Roos (Amsterdam University, the Netherlands), Volker M. H. Rudolf (Rice University, USA), and Hikaru Nakagwa (Kobe University, Japan), respectively. The title of my organizing symposium was “Invitation to body size-based community ecology,” which pointed out the major problem in current ecological research that it has traditionally been based on species taxonomy and tended to ignore important and ubiquitous roles of intraspecific variations due to ontogenetic growth of organisms in ecological dynamics. In the symposium, as organizers, I (NCKU) and Prof. Osamu Kishida (Hokaido Univeristy, Japan) also gave talks on our own research and publications. Notably, this symposium was placed as the most important and prior symposium, S1, held in the meeting. Moreover, I was also invited to give comments on another symposium regarding “sex and community ecology.” Throughout the meeting I could have productive discussion and share future research directions with my inviting or commenting speakers and many other researchers participating the meeting. I’m certain that this visiting was very fruitful not only for me but also for the development of further tight relationship between Taiwanese and Japanese researchers. (221 字)

1. About Meeting and Society
Ecological Society of Japan (日 本 生 態 學 會 ) is an academic, biggest and traditional organization for supporting and facilitating ecological research in Japan. The society was established in 1953 and at present the number of the membership exceeds beyond 4,000 persons. The society has also been well and long recognized as a managing organization of the academic journal named Ecological
Research (published since 1986). Recently, the annual meeting has welcomed foreign researchers, in
particular, famous researchers from US or Europe and young researchers from East Asian countries, thereby becoming a hub-conference in East Asia connecting ecological researchers. This time, about 60 non-Japanese researchers attend this meeting, including 10 from US or Europe and about 20 from Taiwan.

目的
The prior purpose of the present oversea traveling to organize a special symposium, where I aimed to internationally illustrate the general importance of body size-based approach in community ecology, to introduce recent progresses in the research field, and to discuss and share future perspectives with a wide range of ecological researchers. In the symposium, I also talked about my recent achievements about body-size relationships between interacting predators and prey. Further, I attempted to find opportunities of future collaboration between Taiwanese and Japanese ecologists.

過程
The annual meeting was held at Hiroshima, Japan during 2014 March 14th (Fri) to 18th (Tue),
consisting of management meeting, several symposiums, many general presentations (see http://www.esj.ne.jp/meeting/61/meeting_info2/ for more details of the meeting information).
Ecological research is traditionally species-based, and fundamental questions are those such as why many species can coexist, which species exist where and in what numbers, and how they behave. These questions implicitly assume that species are composed of identical individuals with invariant traits. However, this is a simplified assumption and intraspecific variation is ubiquitous in nature, as almost all organisms on the earth are multicellular and exhibit ontogenetic growth from birth to death. Consequently, there remains much room and the necessity in current ecology that it can and must be further developed and modified by incorporating ontogenetic processes of organisms as ubiquitous and crucial factors driving ecosystem dynamics in nature.
To hold the symposium regarding body size-based community ecology, together with a co-organizer Prof Osamu Kishida (Hokkaido University), I invited the three researchers from USA, the Netherlands, and Japan, who are all key persons in my research field. First, Prof. André de Roos (University of Amsterdam) is the author of a monograph entitled “Population and Community Ecology of Ontogenetic Development (de Roos & Persson 2013)” published from Princeton University Press as the latest volume of Population Biology Monograph that is the most authorized textbook in ecology. He
overviewed body size-based community ecology, with the title being “Ontogenetic development: the unique, ecological process we tend to ignore”. Next, Prof. Volker H. W. Rudolf (Rice University) is a pioneer in the study of ecosystem consequences of organismal body size and published a paper on “Population structure determines functional differences among species and ecosystems processes (Rudolf & Rasmussen 2013. Nature Communications).” The title of his talk was “Thinking inside the box: community-level consequences of stage-structure populations.” Finally, Dr. Hikaru Nakagawa (Kobe University) talked about “The effect of individual-level variations of predators and prey body mass on food-web structures in a temperate stream.” As far as I know, he is only the research studying body size-based community ecology in a stream ecosystem. In addition to them, I and co-organized introduced our researches. Prof. Osamu Kishida (Hokkaido University) illustrated the importance of cannibalism, which appears in body size-based ecology but not in conventional species-based ecology. The title of his talk was “Causes and consequences of predator size-structure: experimental studies of cannibalism of larval salamander”. Finally, I talked about “Predator-prey body-size relationships for parameterizing size-structured food webs.” The symposium was very successful with huge audience. Notably, after the meeting I was asked from the meeting committee to write a review paper about the symposium and contribute to Ecological Research.
In addition to organizing the symposium, I was requested to make comments on another symposium on “sex and community ecology” which emphasized the importance of trait differences between male and female individuals in ecological dynamics. Also, I attended all scheduled symposiums and general presentations in the meeting and could have valuable opportunities to communicate with many researchers.

心得及建議
My organizing special international symposium was placed as the most important and prior (S1). Notably, therefore, it may be possible to say not only that I could spread my research ideas to the audience but also that I could widely advertise names and research power/quality of our Department of Life Sciences, National Cheng Kung University, and Taiwan. I’m sure that the names of our department and school are now deeply memorized and fixed among many Japanese ecologists, while it was not so before unfortunately.
During the meeting, I had several offers of discussion and future collaborations from other researchers. This was another big benefit of attending the meeting. I have deeply discussed with several researchers on different topics. Most of discussion was very meaningful in that we could have attained detailed ideas and potential for future collaborations. It should be noted that such researchers were interested in collaborating with our department/school in terms of international collaboration projects or in terms of industry-academia collaboration projects, rather than with me (i.e., Japanese) personally for small ecological projects. I will attempt to incarnate the potential for future collaborations in near future.
