Physiological regulation of body temperature, set at a high level, is one the key features endothermic homeotherms, such as birds and mammals. However, many mammals some have evolved ability for temporal down-regulation core temperature. We investigated how variation in environment temperature habitat primary productivity determine daily among mammalian species. Nearly half minimum species was ...

to evaluate land suitability of aq-qalla region for rainfed chickpea cropping, boolean logic and analytical hierarchy process (ahp) methods were used in geographic information system (gis). to achieve this, firstly, climatic and agronomical requirements of chickpea,were identified according to scientific resources. then, thematic requirement maps were provided. the studied environmental-compone...

Environmental factors can influence diversity and population structure in marine species and accurate understanding of this influence can both improve fisheries management and help predict responses to environmental change. We used 7163 SNPs derived from restriction site-associated DNA sequencing genotyped in 245 individuals of the economically important sea scallop, Placopecten magellanicus, t...

For every $n\in\mathbb{N}$ and $k\geqslant2$, it is known that $k$-edge-colouring of the complete graph on $n$ vertices contains a monochromatic connected component order at least $\frac{n}{k-1}$. $k\geqslant3$, can be replaced by $G$ with $\delta(G)\geqslant(1-\varepsilon_k)n$ for some constant $\varepsilon_k$. In this paper, we show maximum possible value $\varepsilon_3$ $\frac16$. This dispr...

optimal use of lands heavily relies on careful assessment of agro-ecological resources. the present study was aimed to zoning of suitable areas for of soybean cropping in qaresoo basin of golestan province by geographical information system (gis) and analytical hierarchy process (ahp). in this study, environmental components included: minimum, average, maximum temperatures, precipitation, slope...
