Homalodisca vitripennis (Germar) and related species have caused millions of dollars in damage to southern California vineyards in recent years through the vectoring of Pierce's disease. However, the effects of surrounding vegetation on the dispersal and distribution of H. vitripennis are poorly understood. Therefore, the relationship between dispersal rates and patch quality was tested, as wel...

Let ∆̂n,q = ∑n i=1 wi`i andWn = ∑n i=1 wi with wi = p(xi) q(xi) and `i = `(f1(xi), yi)−`(f2(xi), yi). We note that for examples drawn according to q(x), E[∆̂n,q] = n∆ and E[Wn] = n. The random variables w1, . . . , wn and w1`1, . . . , wn`n are iid, therefore the central limit theorem implies that 1 n∆̂ 0 n,q and 1 nWn are asymptotically normally distributed with √ n ( 1 n ∆̂n,q −∆ ) n→∞ −→ N (0,Va...

Mites of family Erythraeidae are parasites in their larval stage and predators in their post-larval stages on a variety of arthropods, among which are important pest species. During 2011-2013, in a faunistic survey of mites associated with beetles of the family Chrysomelidae in Oil and Gas company of Gachsaranregion, Iran. Specimens were preserved in AG (alcohol 75%, glyserin 5%), cleared in la...

background and objectives: tuberculosis (tb) is the major public health problem in the world. each year there are 2-3 million deaths worldwide caused by tb. the increasing incidence of multi drug resistance tuberculosis (mdr-tb) worldwide highlights the urgent need to search for new anti-tuberculosis compounds. it has been reported that medicinal plant, dracocephalum kotschyi, possesses some an...

The objective of this study was to evaluate the biological activities and chemical fingerprint profiles extracts obtained from twelve Achillea L. species (A. lycaonica, A. biebersteinii (syn: arabica), kotschyi subsp. kotschyi, schischkinii, millefolium millefolium, sintenisii, setacea, teretifolia, wilhelmsii santolinoides wilhelmsii), nobilis, goniocephala, spinulifolia). antioxidant, enzyme ...

OBJECTIVE To evaluate the upgrade rate and delayed false-negative results of percutaneous vacuum-assisted removal (VAR) and surgical excision in women with imaging-histologic discordance during ultrasound (US)-guided automated core needle biopsy (CNB) of the breast and to validate the role of VAR as a rebiopsy method for these discordant lesions. MATERIALS AND METHODS Percutaneous US-guided 1...

Two new species of Palapedia Ng, 1993, are described based on material collected from Abu-Musa Island, Persian Gulf during the present study, from Bahrain by the 1937/38 Danish Expedition, and from the Saudi Arabian coast of the Persian Gulf by Michael Apel in 1992-1995. Palapedia persica n. sp. is distinguishable from its congeners by having distinctly large denticles on the upper margin of th...

Chromosome counts and karyotype information from 41 populations of 20 species and 6 varieties of Nicotianeae (Solanaceae) from South America belonging to Bouchetia Dunal (x 5 8), Fabiana Ruiz & Pav. (x 5 9), Leptoglossis Benth. (x 5 10), Nierembergia Ruiz & Pav. (x 5 8, 9), and Petunia Juss. (x 5 7, 9) are given, including first reports from 14 taxa: F. densa Rémy, N. ericoides Miers, and P. pa...

Caryopses of Aegilops kotschyi Boiss. from different positions within the same spikelet differ greatly in their degree of dormancy. Imposition of this dormancy pattern is a correlative phenomenon within the spikelet, inasmuch as the uppermost developing caryopsis is least dormant and its development is associated with the dormancy status imposed on the lower (one or two) caryopses. Differences ...

Phenotypic variation in four natural populations of Parrotia persica (Hamamelidaceae), a species considered a living fossil endemic to the Hyrcanian forest, was evaluated through leaf morphometric and multivariate analysis. Furthermore, plasticity and leaf fluctuating asymmetry (LFA) were studied. Our findings clearly displayed significant divergence among sites. The smallest lamina size, the h...
