Pasoh Celebrates 25 Years of Research: 10-11 Nov 2010
2010 marks the 25th anniversary of the Forest Research Institute of Malaysia (FRIM) and the Pasoh 50-ha plot, a partnership between the Center for Tropical Forest Science-Arnold Arboretum Asia Program and FRIM. In commemoration of the anniversary, FRIM will host a symposium on 10-11 November 2010, highlighting the scientific findings that have resulted from 25 years of collaborative research at Pasoh.

Community Phylogenetics Workshop Held in Beijing
by Yanjun Du
The Institute of Botany of the Chinese Academy of Sciences (IBCAS) hosted CTFS-SIGEO partners in Beijing on 31 July - 6 August for a workshop on community phylogenetics. Nathan Swenson from Michigan State University gave a series of seminars on phylogenetic approaches to diversity, dispersion, and trait evolution. Xiangcheng Mi, Haibao Ren, Jiangshan Lai, Qiong Ding, and Jinlong Zhang led workshops on the application of R and Phylocom to phylogenetic research.
Fifty-five participants from 8 forest dynamics plots in the Chinese Forest Biodiversity Monitoring Network attended the workshop, representing IBCAS, the Institute of Microbiology CAS, South China Botanical Garden CAS, the Institute of Applied Ecology CAS, Wuhan Botanical Garden CAS, and Xishuangbanna Tropical Botanical Garden CAS.

University of Wyoming Ecosystem Services Field Course at Agua Salud
by Trey Crouch
A group of students and professors from the University of Wyoming’s Environmental and Natural Resources Department traveled to Panama at the end of July for a four-week ecosystem services field course. The group included seven students and professors Scott Miller and Fred Ogden, the latter one of four principal investigators on the Agua Salud Project. The course took advantage of the Agua Salud experimental landscape and study sites to provide the students with field and laboratory experience related to tropical forestry and hydrology and involve them in research on the connections between hydrology, geochemistry, and land cover.

The students participated in various hydrological activities, including two geophysical electrical tomography experiments, installation of shallow groundwater-monitoring wells, and collection and lab analysis of water samples taken from the various Agua Salud stream networks. They also participated in forestry fieldwork by taking crown and DBH measurements in the teak and secondary-growth catchments.

Mapping Underway at Rabi, Gabon
Enumeration of the 25-ha Rabi plot in the Gamba Complex of Protected Areas in Southwest Gabon started in mid June 2010 under the direction of Gorky Villa. David Kenfack, CTFS-SIGEO Africa Program Coordinator, visited the plot in July and August to continue training and supervision of the two field teams, each of which consists of six dedicated Gabonese men who work in rotation to ensure continual mapping and tagging.
PHOTO: Left to right: Landry Tchignoumba, Arnaud Mboumba, Pierre Nicaise Guissouegou, Mourel Mouloungui, David Kenfack, Gauthier Moussavou, and Joel Mpira.
More than 1.5 hectares have been tagged and mapped, with an average of 314 trees (dbh ≥ 1 cm) per 20 x 20 m quadrat and 7,800 trees per hectare. Forty-six species and 288 individuals were recorded in the first 20 x 20 m quadrat, with Dichostemma glaucesens (Euphorbiaceae) comprising 29% of the stems. The plot includes several large individuals of the remarkable canopy tree Eurypetalum tesmannii (Fabaceae), which has a shruby habit and can have up to 74 stems.

Videos of Harvard Talks Now Online
Videos of the presentations at the Arnold Arboretum-CTFS Harvard Plant Biology Symposium in April are now available online for viewing at
http://arboretum.harvard.edu/research/center-for-tropical-forest-science-arnold-arboretum-asia-program/pbi/.
Harvard University's Department of Organismic and Evolutionary Biology (OEB) in partnership with the CTFS-Arnold Arboretum (CTFS-AA) program hosted the 6th Annual Harvard Plant Biology Symposium. This year's theme was "Trees and the Global Environment." The symposium was supported by CTFS-AA, OEB, and the HSBC Climate Partnership.
The talks represented both empirical and modeling/theory perspectives from diverse disciplines in plant science and resource economics. Presentations ranged from the functional responses of individual trees to changing environmental conditions all the way up to ecosystem and landscape-scale responses. For more information, please visit: http://www.pbi.fas.harvard.edu/events.htm.

Harvard Forest Plot Underway
by David A. Orwig
Harvard Forest researchers, with the assistance of scientists from CTFS-SIGEO, began the census of woody stems on June 1, 2010. The 35-ha plot is dominated by eastern hemlock and northern hardwood species and will make an excellent comparison with several other hardwood plots in North America and China at similar latitudes.
To date, over 13,000 stems have been tagged, mapped, and measured, representing approximately 4.5 hectares. Some of the quadrats were particularly dense, containing dense thickets of mountain laurel (Kalmia latifolia). Over the course of the summer, Forest Ecologist David Orwig and six crew members will continue sampling in the western portion of the plot.
The Harvard Forest plot forms part of a global array of large-scale plots established by CTFS-SIGEO, which recently expanded sampling efforts into temperate forests to explore ecosystem processes beyond population dynamics and biodiversity. The geography and size of the plot (500 m x 700 m) was designed to include a continuous, expansive, and varied natural forest landscape that will yield opportunities for the study of forest dynamics and demography while capturing a large amount of existing science infrastructure (e.g., eddy flux towers, gauged sections of a small watershed, existing smaller permanent plots) that will enable the integrated study of ecosystem processes (e.g., biogeochemistry, hydrology, carbon dynamics) and forest dynamics. Thus the resulting data will integrate well with ongoing NSF-funded LTER (Long Term Ecological Research) and NEON (National Ecological Observatory Network) studies.
