(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - TD018 During the spring cross-sections 8 cm thick are removed from logs with a chainsaw. These are placed in plastic bag and kept under refrigeration until samples are tested. Two to three samples with a fresh weight of 2 g are removed from each tissue type. These are placed in serum tubes, capped, and incubated at 15°C for 1-2 hours with lab air to determine the respiration rate. The tubes are then purged for 2 minutes with argon, acetylene is injected, and air is injected to give 1% oxygen. Incubations for acetylene reduction are at 15°C for 20-25 hours. Carbon dioxide and ethylene production are measured using a gas chromatograph. Moisture content is calculated after drying the samples 2 days at 70°C. Site 1: elevation is 1065m, average annual temperature 8.9 degree C, average annual precipitation is 229cm. Site 4: elevation is 865m, average annual temperature 9.9 degree C, average annual precipitation is 219cm Sampling frequency: irregular The data are a time series, basically on an annual time step. Regression analysis will be used to test if the rates for species and tissue types changes with time. During any one time the design varies from a split-split plot to a split plot ANOVA. The effects of species, tissue type, or position in the log (top, bottom, side) can be tested.

Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics. Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition. The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources. Data were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program (DEB 2025755), US Forest Service Pacific Northwest Research Station, and Oregon State University. National Science Foundation: DEB1440409 The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms. 1 TD01801 Acetylene Reduction and Respiration: Raw Data: TD01801.csv 184195 3e4cd1d72baa90b2aa29dd946a16a9c2 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=TD01801_v3.csv 1987-03-15 2006-05-15 DBCODE FSDB Database code char(5) TD018 FSDB database code TD018 ENTITY Entity number numeric(2,0) number 1.000000 natural 1.0000 1.0000 STUDYID Location of the sample collection char(4) HJA Andrews Experimental Forest (HJA) YEAR Year of sample collection numeric(4,0) YYYY 1.000000 TIME Time in months that the log has been rotting in the field. numeric(4,0) number 1.000000 natural 4.0000 248.0000 SITE Site that the log samples were removed from; refers to sites described under TD14 studies char(1) 1 End of 327 road 4 W of 350 road near junction of 350 and 1506 SPECIES Species of the log sampled; follows garrison conventions char(4) ABAM Abies amabilis PSME Pseudotsuga menziesii THPL Thuja plicata TSHE Tsuga heterophylla TISSUE Tissue type of the log sampled char(2) HW Heartwood IB Inner bark OB Outer bark SW Sapwood POSITION Position in cross-section sampled char(1) T Top of log S Side of log B Bottom of log M Mixed position; taken from any position randomly NUMBER Number of test tube used for incubation numeric(4,0) number 1.000000 natural 1.0000 741.0000 REP Replicate for species and tissue type char(1) Replicate for species and tissue type ETHYLENE Ethylene produced during incubation numeric(6,3) parts per million 0.001000 real -3.8800 75.9250 ETIME Length of the ethylene incubation numeric(3,0) number of hours 1.000000 natural 0.0000 29.0000 PRODE Production rate of ethylene on a gram dry weight per day basis numeric(7,3) nanomoles per gram per day 0.001000 real -3.7090 129.7900 CO2 CO2 increase over incubation numeric(6,3) percent 0.001000 real -0.3600 3.3000 TIMECO2 Length of the CO2 incubation numeric(5,2) number of hours 0.010000 real -0.0100 4.7500 RESPIR Respiration rate at 15 deg C (dry weight basis) numeric(7,4) micromoles per gram per hour 0.000100 real -2.4400 9.7300 DRYWT Dry weight numeric(4,2) grams 0.010000 real 0.1300 3.8300 WETWT Wet weight numeric(4,2) grams 0.010000 real 0.9500 3.7600 MC Moisture content of the samples numeric(6,1) percent 0.100000 real 6.5000 1488.0000 OXYGEN Oxygen at start of the ethylene incubation numeric(2,0) percent 1.000000 whole 0.0000 2.0000 SAMPLEDATE Date of sample collection date YYYY-MM-DD 3/15/1987 12:00:00 AM 5/15/2006 12:00:00 AM PRIMARY TD01801.NUMBER TD01801.POSITION TD01801.REP TD01801.SPECIES TD01801.STUDYID TD01801.TIME TD01801.TISSUE TD01801.YEAR NOTNULL TD01801.DBCODE TD01801.DRYWT TD01801.ENTITY TD01801.NUMBER TD01801.OXYGEN TD01801.POSITION TD01801.REP TD01801.SPECIES TD01801.STUDYID TD01801.TIME TD01801.TISSUE TD01801.YEAR TD01801.SAMPLEDATE 1832 2 TD01802 Acetylene Reduction and Respiration: Means and Std.
