Beavers Alter Stream Macroinvertebrate Communities in Northeastern Utah

Understanding changes in macroinvertebrate communities is important because they play a large role in stream ecosystem functioning, and they are an important food resource for fish. Beaver‐induced changes to stream morphology could alter macroinvertebrate communities, which in turn could affect food webs and ecosystem function. However, studies investigating the effects of North American beaver activities on macroinvertebrates are rare in the inter‐mountain west, an area with high potential for beaver‐assisted restoration. The aim of this study was to quantify differences in the macroinvertebrate community between unaltered segments of streams and within beaver ponds in north‐eastern Utah, U.S.A. We assessed macroinvertebrate species richness, biomass, density, functional feeding group composition, mobility group composition, and macroinvertebrate habitat characteristics to test the hypothesis that macroinvertebrate communities will differ among habitat types (undammed stream segments and beaver ponds) in beaver‐occupied streams. Beaver pond communities significantly differed from lotic reach communities in many ways. Beaver ponds were less diverse with 25% fewer species. Although there was variability among streams, in general, beaver ponds had 75% fewer individuals and 90% lower total macroinvertebrate biomass compared to lotic reaches. Regarding functional feeding groups, beaver ponds contained more engulfers, while lotic reaches contained more scrapers, filterers, and gatherers. For mobility groups, beaver ponds had more sprawlers, while lotic reaches had more clingers. Swimmers were also more prevalent in lotic reaches, although this is probably due to the abundance of Baetis within lotic reaches. More beaver pond taxa were classified as lentic‐dwelling insects, while more lotic reach taxa were categorised as preferring lotic habitats. The creation of ponds by beavers fundamentally altered the macroinvertebrate community in north‐eastern Utah streams. Such changes to stream macroinvertebrate communities suggest that recolonisation of beavers across North America may be altering stream functioning and food webs. Our study highlights the need to further investigate the effects of beaver recolonisation on stream communities

A Check List of the Lepidoptera of Beaver Creek State Park, Columbiana County, Ohio

Results of a comprehensive survey of Lepidoptera occurring at a 12,334 hectare natural area in Columbiana County. Ohio conducted in 1985 and 1990 is presented. Ten species of skippers, 27 species of butterflies and 597 species and forms of moths were identified and recorded. Euagrotis forbesi, and Spodoptera eridania had not previously been collected in Ohio; and Polia nimbosa and Idia laurenti have been designated as special interest since they are considered rare Ohio residents. The gypsy moth, Lymantria dispar was taken in bait traps and is the first record for that species in the Park. The presence of the gypsy moth, and the possibility of attempted eradication poses a definite threat to the survival of the species mentioned above with the exception of the southern army worm, S. eridama which was undoubtedly a fall migrant

PACKER: a switchbox router based on conflict elimination by local transformations

PACKER is an algorithm for switchbox routing, based on a novel approach. In an initial phase, the connectivity of each net is established without taking the other nets into account. In general, this gives rise to conflicts (short circuits). In the second stage, the conflicts are removed iteratively using connectivity-preserving local transformations. They reshape a net by displacing one of its segments without disconnecting it from the net. The transformations are applied in a asystematic way using a scan line technique. The results obtained by PACKER are very positive: it solves all well-known benchmark example

Beaver bridge

“The Little Beaver Bridge is situated on the A. & P. R. R., 3 ¾ S. W. of Rolla it is built on the “Howe Truss” plan and spans a valley through which flows the “Little Beaver Creek” - it has two approaches (stringers supported by trestles), the length of the northern one is 38 ft., while that of the southern one is 35’5”. The bridge is composed of 5 spans and is supported on 6 piers; the length of the bridge proper is 687’ 2”, with the abutments it is 760’7”. The piers are of sandstone and have a batir, from about one half of their height to the top, of one inch to the foot. In consequence of the comparatively small size of the used in their construction, the Railroad Company has commenced to tear them down in order to erect larger piers. The dimensions of the new piers (for the bottom course) will be 13’1” x 30’ instead of 7’6” x 24’3” as in the old one - the batir will however in the new piers start from the second course. All the timber used in this bridge (except the ties which are oak) is white pine --pages 5-6
