The invasive status of wild barley (Hordeum spontaneum Koch) in Iranian flora

February 2012

The success of a weed’s biological pathway is dependent on several factors including the mechanism(s) of dispersal, longevity of seeds in the soil seed bank, adaptation to varying environmental conditions and, competitive and reproductive abilities. In Near East barley, some races can be identified as wild but in other races wild and weed forms are confounded. Wild barley has wider distribution than the wild wheat...

Agricultural land allocation in small farms around Maasai Mau forest, Kenya and the implications on carbon stocks

February 2012

Recent assessment of the Maasai Mau forest-part of the largest remaining natural forest in Kenya revealed that direct expansion of small farms into the forest in response to population and climate induced land use pressures, largely contributed to a 42% loss in forest cover between 1995 and 2008. In response, the Kenyan government plans to integrate farmers into forest management initiatives through incentive schemes...

Effect of pH decline by acidified spring water on the growth of a submerged macrophyte, Egeria densa (Hydrocharitaceae) in the Kurohashi River, Japan

February 2012

A decline in pH shifts the equilibrium balance of HCO3- -free CO2 towards a regime dominated by free CO2 in the water. Based on the phenomenon, the effect of different pH values on the growth of a submerged macrophyte Egeria densa was investigated in an acidified spring-fed stream in Japan. The growth rate of E. densa during its developing period was found to negatively correlate to...

The celestial factor

December 2011

In reality there are various kinds of explanations for each type of extinction. This paper introduces a new theory to explain and to estimate the size and frequency of all extinctions over the entire period of 600 my of the fossil record. The central point was the search for a common pattern and even one common formula. The explanation seemed to be excellent. We will demonstrate in what way death is a fact of life: by...
