Dear Graduate students,
This is a call for participant of
International Training Course on Environment Science and Ecology which will be
held during July 3rd – 11th, 2019. This course will be conducted in English for
master course, but PhD students who has interest is also welcomed.
The early part of the course consists of various
indoor lecture and technical guidance in Sapporo campus. Then, intensive
field course will be conducted from July 8th until 11th in Uryu Experimental
Forest (Horokanai town) of Hokkaido University. Besides, there will be a short
guidance tour to Botanical garden in the Saturday morning, while no program on
Sunday.
The participant can get 1 credit of
“Special Course for Field Science I” of Graduate School of
Environment Science.
Participant will learn various research
backgrounds, basic theory, current understandings and research approach for
environment science, ecology, biodiversity and ecosystem science through
various group works throughout the course. This program is conducted as a joint

Hokkaido University, which bring a great opportunity to interact with
international students.
There is no course fee. We will use the
shared large bus (with free of charge for participants) to transport between
Sapporo campus and Uryu experimental Forest. Participant has to pay for
the accommodation fee of experimental forest and foods which is a quite

The capacity of participant from Hokkaido
University is about ten students. Please let me know if you are willing to join
this course (Hideaki Shibata, shiba@fsc.hokudai.ac.jp)
(with your name, affiliation, year (i.e. M1 or M2) and the email
address).
The lecturers from Hokkaido University
include Hideaki Shibata, Shunsuke Utsumi, Masahiro Nakamura, Karibu Fukuzawa,
Tatsuro Nakaji, Koh Nakamura and Ram Avtar. The lecturers from National
Dong-Hwa University (Taiwan) consist of Ming-Chien Su, Shih-Chieh Chang
and You-Cheng Hsu.
Please refer the following titles for
lectures and field courses.
Please feel free to ask me if you have any
questions.
Best regards,
Hideaki Shibata
＜Outline of the course>
This is the joint international training
course on ecosystem and environment research. The 10-days course include
several indoor lectures, field course and group work (i.e. discussion and
presentation) in Sapporo campus and Uryu Experimental Forest. Participants will
learn basic theory, recent findings and research methods in field on various
topics in ecology, ecosystem and environmental science. The lecture will be
given by several professors of Field Science Center for Northern Biosphere,
Hokkaido University and Department of Natural Resources and Environmental
Studies, National Dong Hwa University (Taiwan). This course is conducted based
on the MOU between Hokkaido University and National Dong Hwa University.

Title: Strategies and resource acquisition of ectomycorrhizal fungi and wood decay fungi in forest ecosystems
Abstract:
We present two case studies of fungal functioning in forest ecosystems. In the first, we investigated functional differences in six taxa of decay fungi during a long-term log decomposition study (Oregon, USA) by studying elemental, isotopic, and compositional patterns in wood, cellulose, and sporocarps. Partitioning between protein and non-protein pools in mycelia prior to sporocarp formation controlled sporocarp δ15N relative to N sources. Radiocarbon measurements separated fungi into heartwood colonizers (Fomitopsis and Hericium, ~60-year-old carbon) and sapwood colonizers (Mycena (7 years), Hypholoma (11 years), and Trametes (11 years). Mycena and Hypholoma appeared to assimilate some 13C-enriched sucrose in sapwood rather than just cellulose. The six taxa varied widely in their chemical composition, as assessed by pyrolysis GC-MS; these compositional differences correlated with functional growth strategies. From these measurements, we improved the quantitative and conceptual understanding of functional differences of wood decay fungi. In the second study, we assessed how nitrogen (N) availability affected ectomycorrhizal functioning in two long-term (6-40 years) N addition experiments in Pinus sylvestris stands in Sweden. Sporocarp production declined dramatically with N fertilization but recovered slowly after fertilization stopped. Both sporocarp C/N and soil C/N increased with fertilization, implying that N uptake per unit fungal growth increased and then declined after fertilization had stopped. Fungal and soil d15N patterns across treatments identified fungal N sources, with N acquisition primarily from the S horizon for Paxillus involutus and Suillus variegatus, from the F horizon for four Cortinarius taxa and Lactarius rufus, and from the H horizon for Cortinarius traganus and Russula aeruginea. Taxa with proteolytic capabilities were particularly sensitive to N fertilization. These analyses illustrated that responses of fungal taxa across these fertilization gradients depended on the horizon of N acquisition and on N acquisition strategies.
