Creating innovative ways for the identification of trends is a very vital part atmospheric studies. Different climatic locations present their unique variations, calling dynamism trend analysis. In addition to widely adopted Mann–Kendall (MK) test, new Şen’s analysis (ITA) method has been applied analyze refractivity related (atmosphere pressure—AP, vapour pressure—VP, ambient temperature—T) an...

The dynamics of Canadian lynx (Lynx canadensis) abundance are geographically structured according to the influence of large-scale climatic regimes. Here we demonstrate that this structuring matches zones of differential snow conditions, in particular surface hardness, as determined by the frequency of winter warm spells. Through a modified functional response curve, we show that various feature...

Zygophyllum atriplicoides is one of the important species of Iran rangelands that has special importance owing to some properties like high distribution rate, coverage percentage, density, and plant biomass that make it possible to supply a part of forage needed by livestock during spring and winter as well as to avoid soil degradation against water and wind erosions. This research tries to stu...

We use two methodologies, the least square dummy variables approach and the dynamic factor models, to decompose the labor productivity growth rate for a large sample of countries into common, i.e. global, and idiosyncratic, i.e. country, components. We find that country specific effects are much more important than common effects in explaining labor productivity. The interesting result is that,...

The aim of this study was to evaluate the heartwood, sapwood and bark content, and wood dry density in young and mature teak (Tectona grandis) trees. For this, 17 plantations were selected from 11 sites representing different climatic conditions and plantation densities (156 to 1600 trees ha–1, and line planting). From these plantations, a total of 87 trees with ages between 5 and 47 years were...

Aim The study was undertaken to assess the prevalence of antibodies to Capripoxviruses among small ruminants of Odisha, India. Materials and Methods A total of 500 random serum samples collected from 214 sheep and 286 goats across 10 agro-climatic zones of Odisha, were screened using whole virus antigen-based indirect ELISA for antibodies against Capripoxviruses. Results were analyzed by suit...
