Between 1986 and 1995, 548 fecal samples were collected from 41 species of bats (Molossidae, Mormoopidae, Phyllostomidae, Thyropteridae, and Vespertilionidae) from New Mexico, California, Baja California Sur (Mexico), and Bolivia. Of these, the feces of 28 (5%) bats, including Antrozous pallidus, Myotis ciliolabrum, Myotis lucifugus, and Myotis yumanensis (Vespertilionidae), contained oocysts r...

More than 1,180 fecal samples were collected from 253 juvenile and 384 adult Townsend's ground squirrels (Spermophilus townsendii) at the Snake River Birds of Prey Area near Boise, Idaho, from February to June 1992. Oocysts of 7 eimerians were observed. Five are new host records (Eimeria beecheyi, Eimeria bilamellata, Eimeria callospermophili, Eimeria lateralis, and Eimeria morainensis), 2 spec...

Two new species of Eimeria were observed in the feces of captive white-tailed deer fawns, Odocoileus virginianus, from Alabama. The first new species was easily recognized because of its small size. Sporulated oocysts are spherical, average 10.2 by 10.0 microm, and lack a micropyle and oocyst residuum. Oocysts contain a polar granule and elongate-ellipsoidal sporocysts that measure 6.7 by 3.1 m...

Genes directly involved in male/female and host/parasite interactions are believed to be under positive selection. The flowering plant Arabidopsis thaliana has more than 300 defensin-like (DEFL) genes, which are likely to be involved in both natural immunity and cell-to-cell communication including pollen-pistil interactions. However, little is known of the relationship between the molecular ev...

Two hundred and twenty-four anurans of 6 species (47 adults and 16 tadpoles of Rana blairi, 35 R. catesbeiana, 31 Hyla chrysoscelis, 30 adults and 46 tadpoles of Pseudacris triseriata triseriata, 11 Bufo woodhousii, and 8 Acris crepitans) from Pawnee Lake, Lancaster County, Nebraska, were surveyed for coccidian parasites during March 2001 to May 2002. Of these, 23 of 30 (77%) adults and 4 of 46...

Fruit of 85 varieties of Pakistani dates were collected throughout the harvest season. Appropriate Performa was designed to write the scientific and commonly used properties. These properties included fruit color at Khalal stage, shape, size (length & diameter), color & height of perianth, fruit group (soft, semi-dry, dry), edible stage and the micropyle position and split (wide, narrow, deep)....

Structural features of the eggs of a basal phasmatodean, Timema monikensis Vickery & Sandoval, 1998 (Timematidae) were examined. The eggs of this species are soft and deposited coated with soil and/or other extraneous particles. The chorion, which is transparent and weakly sclerotized, is composed of an endochorion and an exochorion. The non-inclined operculum is located at the anterior pole of...

Vertical orientation of emerging roots typically is the first response of plants to gravity. Although root gravitropism has been studied extensively, no conclusive data on the onset of gravisensing exist. We determined the inception of gravisensitivity in flax (Linum usitatissimum) roots by clinorotating germinating seeds after various periods of static orientation (gravistimulation) of imbibed...

A library of monoclonal antibodies, raised against imaginal discs of Drosophila melanogaster, was screened for binding to differentiation antigens in the adult ovary by immunofluorescence. Several lectins were similarly assayed. Two antibodies, DOV 1 and DOV 2, and wheat germ agglutinin exhibited binding which was restricted to particular stages of ovarian cell differentiation. DOV 2 also showe...

Blood films and fecal samples of the lesser prairie-chicken (Tympanuchus pallidicinctus) were examined for parasites when we surveyed specimens captured during a radio-tracking study conducted in Chaves County, New Mexico (USA). All birds were captured on the Caprock Wildlife Habitat Management Area, administered by the Bureau of Land Management. Samples were collected in late March, April, and...
