The ability to resist hurricane damage is a property of both individuals and communities, and can have strong effects on the structure and function of many tropical forests. We examined the relative importance of tree size, species, biogeographic origin, local topography, and damage from previous storms in long-term permanent plots in a rehabilitated subtropical moist forest in Puerto Rico foll...

We use the lace expansion to prove asymptotic formulae for the Fourier transforms of the r-point functions for a spread-out model of critically weighted lattice trees in Z for d > 8. A lattice tree containing the origin defines a sequence of measures on Z, and the statistical mechanics literature gives rise to a natural probability measure on the collection of such lattice trees. Under this pro...

The plum (Prunus cerasifera Ehrh) has been used worldwide both as a genetic source for breeding new rootstocks and clonal rootstock many Prunus species. Considering situations where wild relatives of plums are endangered, in-depth characterization traits diversity germplasm Turkey with ecogeographical locations is crucial. In the present study, therefore, three steps were followed selection can...

Invasive alien insects cause serious ecological and economical losses around the world. Here, we review bionomics, modern ranges (and their dynamics), distribution pathways, monitoring, control measures of 14 insect species known to be important invasive emerging tree pests in forest urban ecosystems Russia: Leptoglossus occidentalis (Hemiptera: Heteroptera: Coreidae), Halyomorpha halys Pentato...

Many biogeographic problems are tested on phylogenetic trees. Typically, the uncertainty in the phylogeny is not accommodated when investigating the biogeography of the organisms. Here we present a method that accommodates uncertainty in the phylogenetic trees. Moreover, we describe a simple method for examining the support for competing biogeographic scenarios. We illustrate the method using m...

The case is described of a 31 year old woman who presented with complaints of recurrent haemoptysis coinciding with menstruation. Bronchoscopic examination revealed multiple purplish-red submucosal lesions on the right side of the trachea and bilateral bronchial trees which appeared during her menses and regressed in the intermenstrual periods. Brush cytology revealed cell clusters consistent w...

using microsatellite molecular markers is important particularly due to their high accuracy in studying the genome of the fruit trees. in this study, genetic diversity and relations of 68 almond cultivars and genotypes using microsatellite marker (ssr) were studied. genomic dna extracted from young leaf tissues and pcr reactions were performed using 22 selected primers (among 100 primers) of mi...

A tree T of order n is called k-placement if there are k edge-disjoint copies of T into K_{n}. In this paper we prove some results about 4-placement of rooted trees.
