Using mainly published data from 1932 to 2010, we have assembled three data sets: (1) body composition (wet, dry, and ash-free dry mass, C, N, P as a percentage of wet and dry mass, and C:N), (2) length–mass biometric equations, and (3) mass–mass biometric equations. The ...
Mars's tragedy is that it is too small, and fell into a deadly spiral. Because of its smaller mass, there was insufficient gravity to hold on to its atmosphere, the drop in atmospheric pressure was inexorable, and the solar wind swept it all away.火星的悲剧在于它太小了，而且陷入了致命的...

How life on Earth began remains an unexplained scientific problem. This problem is nuanced in its practical details and the way attempted explanations feedback with questions and developments in other areas of science, including astronomy, biology, and p
“free water must evidently evaporate before the absorbed moisture in the cell walls can begin to dry out”. Additionally, for absorption, Tiemann suggests that water is first added to the cell wall and only after the cell wall is saturated, free water (capillary water) is present in voids....
Fire can destroy organic soils in sedgelands (Pemberton1988) and rainforests (Hill1982). Furthermore, the soil nutrient capital of forests and sedgeland is reduced by fire through volatilisation and transport of ash (Harwood and Jackson1975; Bowman and Jackson1981), soil erosion (Wilson1999; ...
