This data set was developed as part of MS thesis research requirements in conjunction with the Cooperative Forestry Ecosystem Research (CFER) project. Study objectives were to 1) identify habitat characteristics with an emphasis on riparian vegetation associated with the presence of two salamander species and 2) to describe diet-habitat relationships, emphasizing riparian vegetation.
AQUATIC SURVEYS We conducted aquatic surveys in July and October 2002, and June 2003 in ten, 2-m long transects in each stream. October sampling occurred before significant fall rain and associated leaf fall. Stream transects were eight m apart and spanned the bankfull width of the stream. During each of the three aquatic sampling periods, we measured microhabitat characteristics in five transects per stream. We measured active channel width across the upper, middle, and lower end of the transect. We measured stream depth at five evenly spaced points across the lower end of the transect. We used a moosehorn to measure the total shrub and overstory cover, then separately measured the three dominant shrub and overstory species over the wetted width of the transect. We took three moosehorn readings for each shrub and overstory variable; one from the center of the wetted width, and 10 cm from the water’s edge on each side of the stream. Multiple measurements taken within each transect were averaged for that transect. Transect gradient, upslope gradient (to 30 m), and the amount of area covered by down wood (>5 cm in diameter) were measured during the first aquatic sampling period only.
TERRESTRIAL SURVEYS We used a pitfall grid that was installed in the center of each site and consisted of 30 traps in three rows of ten traps running parallel to the stream. We constructed pitfall traps with two, #10 tin cans taped together and placed into the ground with the edge of the can flush with the ground surface. Traps were covered when not in use. We randomly located 1- by 2-m quadrats (plots) within the site which were sampled once per season. In addition, we placed nine, 0.09-m2 untreated Douglas-fir coverboards and six, 1-m2 pieces of black plastic upstream and downstream of the pitfall trapping grid to augment terrestrial amphibian detections/captures (outside of the "site", i.e., the 100-m riparian area that paralleled the length of stream used for aquatic surveys). We conducted terrestrial amphibian surveys in fall 2002 and spring 2003 (the wettest times of the year). Due to unseasonably cool, dry weather in fall 2002, pitfalls were open for one trap night and 14 quadrats were searched at each site. In spring 2003, pitfalls were open for three consecutive nights at each site and checked each subsequent morning. In spring 2003, we searched a total of 44 quadrats per site over the 3 day survey period for amphibians and characterized vegetation and microhabitat components in 28 randomly selected quadrats over the same three-day sample period. We checked under cover objects daily during the survey period.
INVERTEBRATE COLLECTION We collected aquatic benthic invertebrates using a 0.09-m2 surber sampler with a 500 µ mesh sieve at six randomly selected locations each aquatic sample period. Surber samples were stored in whirl packs in a 95% ethanol solution. In the lab, samples were pooled by site and season, sorted, and invertebrates were identified under 10-30x dissecting microscopes. We sampled terrestrial invertebrates at ten randomly located invertebrate pitfall traps within each study site. Invertebrate pitfall traps were constructed of 1-quart plastic containers and were open for the duration of the terrestrial survey period (one or three trap nights). At the end of each survey period, the container was capped and returned to the lab. We collected five soil samples, 15 by 15 by 5 cm, at random locations on the last day of the survey period for each site. Each sample included the surface vegetation and litter layer and 5 cm of soil. Invertebrates were extracted over a five day period by Berlese funnel traps (Oregon State University Department of Entomology) and preserved in 95% ethanol until identified. Aquatic invertebrates were identified to Order where possible. Terrestrial samples were pooled by site and season and invertebrates were identified to Order where possible.
STOMACH SAMPLE PROCESSING We collected stomach samples from all amphibians captured, except from torrent salamanders (Rhyacotriton spp.) or larval tailed frogs (Ascaphus truei). In the lab, we photographed each stomach sample in a Petri dish and a ruler (for scale) and measured the surface area (mm2) covered by stomach contents (Image Pro Plus, version 4.5.0.29, Media Cybernetics, Inc software). We developed an index of stomach fullness by dividing stomach content surface area by the SVL of an individual, which allowed us to account for its size when making comparisons of stomach fullness. After photo measurement, we counted and identified prey items to Order where possible. We considered slugs and snails in Class Gastropoda as separate prey categories. We counted an invertebrate head found in a stomach sample as one invertebrate prey item.
Reference:
No tests for attribute accuracy were conducted.
Only down wood (DW) in streams > 5 cm diameter were measured for instream (aquatic) wood cover. Only DW, stumps, or snags in riparian area > 10 cm diameter were included. Only streams that could be searched by hand, occurred in 2nd-growth forests were considered for inclusion in site selection process
