Use of gap (created by tree falls) and non-gap forest understory sites by migrating birds in central Illinois was studied during spring and autumn for three years (19781980). Fruit and understory foliage were concentrated in gaps. Birds that relied on these resources (foliage-gleaning insectivores, frugivores in autumn) used gaps more than non-gaps. Birds that fed on food other than fruit and f...

1. Carbonic anhydrase was measured in tissues of silkmoths, Hyalophora cecropia, reared on either a wheatgerm-based synthetic diet or wild cherry foliage in feeding fifth-instar larvae, throughout the larval-pupal transformation and in newly ecdysed pupae. 2. Carbonic anhydrase activity was present in fat body, midgut and intgeumentary epithelial cells, but not in haemolymph, cuticle or the int...

First rotation Pinus radiata D. Don trees were grown on a nitrogen-deficient sand dune in an experimental design that included lupin (Lupinus arboreus Sims) as an understory species, and biennial application of balanced fertilizer in a replicated split-plot factorial design with thinning treatments as subplots. From an initial 2222 stems ha(-1), stands were thinned to 1483 and 741 trees ha(-1) ...

INTRODUCTION Foliage plants, defined literally, would include all plants grown for their attractive leaves rather than for flowers or fruits. In general horticultural terms, however, foliage plants are mostly those with attractive foliage and/or flowers that are able to survive and grow indoors. Thus, they are used as living plants for interior decoration or interior plantscaping. Foliage plant...

A high level of genetic variability for growth habit types is observed in tetraploid, cultivated coleus (Solenostemon scutellarioides (L.) Codd). Very few cultivars with trailing habit exist, and those that are available generally have dark green or purple foliage color. Coleus with trailing growth habit is desirable as it increases its utility for use in hanging baskets, mixed containers, and ...

In this section we consider the problem of radar detection of stationary targets obscured by foliage clutter. This is a classical detection problem for which the usual solution approach is to reduce the radar centre frequency as far as possible, so minimising scattering by the foliage while hopefully maintaining a significant target response. These approaches are based on backscatter intensity ...

Nitrate toxicosis associated with consumption of pigweed red-root (Amaranthus retroflexus) wasdiagnosed in a small herd of cattle in the suburb of Mashhad, northeastern Iran. The clinical signs wereruminal tympany, incoordination, tachycardia, dyspnea, head pressing, aggressive movements and jugulardistension. Seven animals including 3 young calves and 4 cows died of intoxication; other affecte...

Three species of aphids attack pecan foliage, Carya illinoensis (Wang.) K. Koch, and cause economic damage. We tested a kaolin-based particle film against one of these aphid species, black pecan aphid, Melanocallis caryaefoliae (Davis). Effect of particle film on host selection, adult mortality, and production of nymphs by M. caryaefoliae was tested on seedling pecans in the laboratory. Fewer M...
