Effects of harvesting ruminal micro-organisms from ruminal ̄uid on patterns of gas production were investigated in experiment 1 by incubating 200 mg DM of pure cellulose, oatfeed, ryegrass, cocksfoot, wet and dry season kikuyu grasses with either diluted ruminal ̄uid or harvested ruminal bacteria. Gas production degradability parameters obtained from ®tting the data to the model Gas ˆ B(1ÿ expÿ...

The objective of this study was to compare heifer growth and reproductive performance following 2 levels of stockpiled fall forage allowance of orchardgrass (30.5%) and tall fescue (14.1%). Spring-born heifers (n = 203 and BW = 246 ± 28.9 kg) of primarily Angus background were allocated to 2 grazing treatments during the fall period (November 12 to December 17 in yr 1, November 7 to January 4 i...

A 40% rumen fluid basal medium has been developed that without added substrate will support growth of about 10% or less of the total colony count obtained with 40% rumen fluid-glucose-cellobiose-starch-agar medium (RGCSA). The basal medium is prepared by anaerobic incubation of all ingredients in RGCSA medium except the carbohydrates, Na2CO3, and cysteine for 7 days at 38 degrees C. After incub...

Squat lobsters from Madagascar, Vanuatu, Papua New Guinea, Fiji, eastern Australia and French Polynesia belonging to the Agononida incerta (Henderson, 1888) species complex are described as four new species: A. madagascerta, A. polycerta, A. tasmancerta and A. vanuacerta. This brings to ten the number of species in this complex. All species are morphologically distinguishable only on the basis ...

Orchardgrass is a member of the Poaceae, a family characterized by monocotyledonous-type embryos. This species is unique in that somatic embryogenesis can be induced from the cultured leaves of potted plants, which can be maintained conveniently in the greenhouse. Both embryogenic callus and isolated somatic embryos develop directly from cultured leaf sections. Embryogenic callus can be maintai...

Two species of paguroid hermit crabs, Ciliopagurus liui Forest, 1995 (Diogenidae) and Pagurus spinossior n. sp. (Paguridae), are reported from the Kerala State, southwestern India. Ciliopagurus liui, is first recorded from the Indian Ocean. This species was originally described on the basis of a single male specimen from the Tonkin Gulf in the South China Sea, though its geographical range also...

Increasing plant diversity in the perennial phase of pasture-crop rotations is predicted to positively affect belowground productivity and microbial communities and, turn, augment agroecosystem services including soil health carbon storage. Using two grass one legume forage species grown as monocultures combined four intercropped combinations, we evaluated how identity richness influence produc...

Pieris napi oleracea Harris is a native pierid butterfly that has suffered a range reduction in New England that began after the invasion of its range by the non-native congener Pieris rapae L. and one of its braconid parasitoids, Cotesia glomerata (L.). P. napi has nearly disappeared from Massachusetts, but remains common in northern Vermont. We investigated food plant abundance and Cotesia sp...
