In southeastern Coastal Plain streams, wood debris can be very abundant and is recruited from extensive forested floodplains. Despite importance of wood debris, there have been few opportunities to examine recruitment and redistribution of wood in an undisturbed setting, particularly in the southeastern Coastal Plain. Following extensive flooding in 1994, measurements of individual downed trees...

I propose the development of a fuzzy set ordination (FSO) approach to old-growth classification of southern pines. A fuzzy systems approach differs from traditional old-growth classification in that it does not require a “crisp” classification where a stand is either “old-growth” or “not old-growth”, but allows for fractional membership in the set of old-growth stands. FSO produces a score rang...

No doubt about it, wood complicates fluvial geomorphology. It messes up nice tidy streams, complicates quantitative analysis, invalidates convenient assumptions, and opens new questions about how different contemporary channels are from their pristine state. It is no coincidence that modern fluvial geomorphology developed through the study of channels lacking a substantial load of wood debris (...

酵素により米のデンプンを分解し液化処理する清酒製造法が普及し，食用に適さない粗蛋白質含量の高い酒粕（高CP酒粕）が産出されている。しかし，高CP酒粕は，日本標準飼料成分表（2009年版）に示されている酒粕（酒粕（乾），CP36.9%DM）とは栄養成分値が大きく異なり，豚における消化率及び栄養価は不明である。そこで，高CP酒粕について，消化率及び栄養価を明らかにするために消化試験を実施した。最初に，供試品選択のために，18点の家畜飼料向け酒粕の栄養成分値及びアミノ酸含量を分析した。その結果，家畜飼料向け酒粕の凍結乾燥品のCP含量は13.9～69.2%DM（平均36.1%DM）と変動が大きかったが，アミノ酸含量（%CP）は比較的一定であった。事前調査において最も高いCPの酒粕を生産していた酒蔵由来の高CP酒粕の乾燥品（CP73.5%DM）を供試品として選定した。LWD三元交雑種の肥育豚（...

Three-dimensional high-resolution images of density distributions were obtained on unsplit cores using a medical X-ray computed tomography (CT) scanner. The resolution of CT scanning is about 0.6 mm2 and allows a 5-mm depth for beam width. Electrical resistivity measurements were also conducted to know porosity at high depth resolution after core splitting. Wholeround core samples for this stud...

—In June 1995, a massive flood and debris flow impacted fish and habitat along the lower 1.9 km of the Staunton River, a headwater stream located in Shenandoah National Park, Virginia. In the area affected by debris flow, the stream bed was scoured and new substrate materials were deposited, trees were removed from a 30-m-wide band in the riparian area, and all fish were eliminated. In the area...

s Research Symposium January 2007 Graduate Student Association Department of Natural Resources Cornell University Charlotte Acharya and Bernd Blossey Invasive species: Can they be controlled? Non-native invasive species are considered a serious ecological and economic threat. Because of this, an increasing amount of resources are being devoted to invasive plant removal. Additionally, within the...

This proposal is for an IODP program to constrain models for the formation of deep sea gas hydrate in subduction zone accretionary prisms. The objectives include the deep origin of the methane, its upward transport, its incorporation in gas hydrate, and its subsequent loss to the seafloor. The main attention is on the widespread seafloor-parallel layer of dispersed hydrate located just above th...
