2 wrz 2011 · The geometric mean of relative abundance indices, G, is increasingly being used to examine trends in biological diversity and to assess whether biodiversity targets are being met. Here, we explore the mathematical and statistical properties of G that make it useful for judging temporal change in biological diversity, and we discuss its ...
1 kwi 2016 · There are several concepts of allometry, which all concern the effect of size on morphological variation, but differ in the specific definitions of terms and in the aspects of morphology on which they focus.
1 gru 2007 · Because the geometric mean is G ≈μ−σ 2 / (2 μ), where μ is the (arithmetic) mean and σ 2 is the variance in absolute fitness, the allele favored by natural selection is the one that best boosts μ while reducing σ 2.
In this same spirit, we aim to characterize the sizes of things in molecular and cellular biology with the hope of garnering insights into the kinds of functional implications explained by Haldane at larger scales.
10 paź 2007 · Because the geometric mean is G≈μ−σ 2 /(2 μ), where μ is the (arithmetic) mean and σ 2 is the variance in absolute fitness, the allele favored by natural selection is the one that best boosts μ while reducing σ 2.
31 sie 2011 · Does cellular structure persist across cell generations? What is the relationship between cell geometry and tissue organization? What ensures that intracellular structures are scaled to the overall size of the cell? Cell biology is only now beginning to come to grips with these questions.
