    Reproductive Patterns of Captive Lesser Bandicoot Rat (Bandicota Bengalensis Gray) in the Punjab
    (1978-01) Sagar, Prem; Bindra, O. S.
    Development of the lesser bandicoot rats was studied under caged conditions. Early development of both sexes was similar. Walking started (14 days) at about the time sensory organs became functional. Body weight in males continued to increase for about 9 months. After about 5 months, weights of females fluctuated with pregnancies. Sexual maturity was attained by 60 days in females, slightly earlier in males (51 days). A female might produce 9 litters annually; mean litter size was 5.4 Sex ratio was 41% males.

    Feather Morphology as an Age Indicator in Mandarin Ducks
    (1978-01) Bruggers, Richard L.
    An investigation of known-age Mandarin ducks {Aix galericulata) indicated that primary feather length and secondary feather markings could be used to separate the majority of yearling from adult birds. The lengths of the 7th, 9th, and 10th primaries of adults of both sexes were longer than the corresponding feathers in yearlings. The 7th and 9th primaries probably would provide the greatest ageing accuracy, since their lengths were significantly different when the same females were measured as yearlings and adults. Color patterns on the secondaries could not be used to segregate age groups reliably.

    Effect of Suspended Iron Hydroxide on the Hatchability and Embryonic Development of the Coho Salmon
    (1978-01) Brenner, Fred J.; Cooper, W. Lynn
    Coho salmon (Oncorhynchus kisutch) eggs were fertilized and fry were incubated at 10°C in the presence and absence of suspended iron. Suspended ferric hydroxide at a concentration of 3 ppm had no apparent effect on the hatchability, embryonic development, or survival and maturation of newly hatched coho salmon still attached to the yolk mass (alevins).

    Antigenic Relationships Among Floc-Forming Pseudomonadaceae
    (1978-01) Chorpenning, Frank W.; Schmidt, David H.; Stamper, Hugh B.; Dugan, Patrick R.
    A number of cross-reactions were observed between the antigens of flocforming pseudomonads. Immunodiffusion tests of trichloroacetic acid extracts showed that antigens are shared by some Zoogloea spp. and Pseudomonas spp., yet other Zoogloea and Pseudomonas spp. lack these antigens. One of the antigens was also found in Gluconobacler. This demonstration of a close antigenic relationship between some, but not all, members of the 3 genera must be weighed against the limited number of characteristics which establish the generic distinction.

    The Use of the Bitterlich Sampling Technique in an Athens County, Ohio Forest
    (1978-01) Held, Michael E.; Wistendahl, Warren A.
    The Bitterlich variable radius method of forest sampling was used in an upland oak forest at the Waterloo Wildlife Research Station in Athens County, Ohio. Species and density data were recorded for 52 Bitterlich points included in the area sampled. Minimum sample size was determined using the running means test and an estimate of the number of points needed to obtain a standard error within 5% of the mean. These tests led to the selection of a minimum sample size of 14 Bitterlich points.

    Crustacean Zooplankton in Lake Erie Off Cleveland Harbor
    (1978-01) Czaika, Sharon C.
    Zooplankton samples were collected from 5 stations in Lake Erie off Cleveland Harbor in June, August, and November 1973 and April 1974. Identification of 26 zooplankton groups was made, the most common being (in decreasing order of abundance) copepod nauplii, bosminids with mucro, immature cyclopoid copepodids, Eubosmina coregoni, Daphnia retrocurva, Cyclops bicuspidatus thomasi, immature calanoid copepodids, Daphnia galeata mendotae, Cyclops vernalis, Ceriodaphnia lacustris, Mesocyclops edax. Crustacean zooplankton were most abundant in June (158,000/m3) and least abundant in November (27,600/m3). Cladocerans were dominant only in August. Nauplii accounted for 82% of all zooplankton in April. Comparison of the seasonal abundance of immature dipatomid copepodids suggests that breeding seasons were probably similar in the 1950's and 1970's. It appears that the crustacean zooplankton community off Cleveland Harbor probably has not changed significantly since the mid-1950's.

    Friction Cracks as Directional Indicators of Glacial Flow on Mt. Desert Island, Maine
    (1978-01) Slocum, Robert D.
    A detailed study of friction cracks from a Late Pleistocene glacial pavement on the southeastern corner of Mt. Desert Island, Maine, has shown that these small scale glacial erosion features may be used as reliable indicators of the direction of glacial flow. Directional information suggests that ice flows in response to microand macrotopography in a limited area. Direction of concavity for a given type of friction crack is constant, but concavity is a useful tool in determining the direction of ice flow only if one distinguishes between crescentic gouges (concave upsteam with respect to glacial flow) and both lunate fractures and crescentic fractures (concave downstream). In non-schistose rock types, the most consistent friction crack parameter is primary fracture dip, which is downstream in the direction of ice movement.

    Color Patterns on Pennsylvanian Gastropods from Ohio
    (1978-01) Hoare, Richard D.; Sturgeon, Myron T.
    Gastropods are among the more common fossil forms with preserved color patterns. Numerous species of Carboniferous gastropods have been previously reported in Europe and North America including 9 species from the Pennsylvania!! of Ohio. Our collections of Pennsylvanian gastropods, made over the past several years, contain specimens representing 11 species with remnants of color patterns, 9 not previously reported from Ohio. The color patterns of 4 of these species, Ianthinopsis intercalaris? (Meek & Worthen), Palaeostylus (Paleostylus) n. sp., Palaeosiylus {Pseudozygo pleura) n. sp. 1 and Palaeostylus {Pseudozy go pleura) n. sp. 2, have not been described before. Comparisons were made between Ohio gastropods with color patterns, or closely related forms, and those reported elsewhere. Variation in patterns were noted and illustrated where possible.
