Potamonautid river crabs were collected from 9 localities in Mpumalanga and Northern Province, South Africa. in order to determine morphological and genetic variation among these populations. Based on the presence or absence of epibranchial teeth. gonopod I shape, and marked allozyme divergence, 2...
What Determines Species Diversity ?地球上存在着无数的各种各样的植物、动物和微生物,它们充斥着地球上每一块陆地的每个角落和每一片海洋的每一条缝隙。它们的存在和活动使得世界得以运转,首先它们能将阳光转化成其他生命能够加以利用的能源,使碳和氮在无机物和有机物的形式间循环转化,其次它们的存在和活动在不断...
Diverging in the initial assumptions, both mechanistic and evolutionary theories of aging suggest a positive correlation of indicators of life expectancy of animal species with body size and a negative correlation with fertility and metabolic rate. Such dependence is obviously traced within large taxa; ...

The geographical range sizes of individual species vary considerably in extent, although the factors underlying this ...
Genotyping determines differences in genetic complement by comparing a DNA sequence to that of another sample or a reference sequence. It identifies small variations in genetic sequence within populations, such as single-nucleotide polymorphisms (SNPs...
