The Swofford-Olsen-Waddell-Hillis (SOWH) test evaluates statistical support for incongruent phylogenetic topologies. It is commonly applied to determine if the maximum likelihood tree in a phylogenetic analysis is significantly different than an alternative hypothesis. The SOWH test compares the observed difference in log-likelihood between two topologies to a null distribution of differences i...
rhizosphere has different chemical and biological properties from the bulk soil. information about phosphorus (p) availability in the rhizosphere soils treated with municipal sewage sludge (mss) is limited. therefore, the objectives of this research were to evaluate the rhizospheric effects of wheat (triticum aestivum l.) on phosphorus availability and biological properties in 10 calcareous soi...
Background Rising atmospheric CO2 concentrations can increase crop yields; however, it is poorly understood if plants require higher phosphorus (P) inputs to support increased production. In addition, soils with contrasting P-sorption capacities may alter plant response elevated CO2. Aims We examined the effect of on critical soil available P and shoot for growth in capacities. Methods Response...
Northern pike, Esox Lucius , is one of the most important species for recreational fisheries in Sweden and as a top-predator; it holds an role food web. Despite its ecological socioeconomic significance, pike largely neglected current monitoring programs because seldom caught by conventional methods. As result, there not sufficient data management authorities to employ biologically justified st...
‘Tree-pasture’ silvopastoral systems have the potential to become transformative multifunctional landscapes that add both environmental and economic value pastoral farms. Nevertheless, no published study has found increased pasture production under mature trees in New Zealand hill country. This takes a novel approach research Zealand, investigates genus similar bio-physical attributes other glo...
AIM The aim of this in vitro study was to compare the flexural strength, the flexural modulus and compressive strength of the acrylic polymer reinforced with glass, carbon, polyethylene and Kevlar fibres with that of plain unfilled resin. MATERIALS AND METHODS A total of 50 specimens were prepared and divided into 10 specimens each under 5 groups namely group 1- control group without any fibr...
Postpartum mental health study flawed by fetal loss omission The recent study of postpartum psychiatric illness [1] is unfortunately flawed by the decision by Munk-Olsen et al. to exclude effects of prior pregnancy losses. Numerous studies (including one by Munk-Olsen) have shown that prior induced abortion or miscarriage increases the risk of postpartum psychiatric disorders [2,3]. Indeed, mul...
