Kidney mass and relative medullary thickness of rodents in relation to habitat, body size, and phylogeny.

摘要: Abstract We tested the hypotheses that relative medullary thickness (RMT) and kidney mass are positively related to habitat aridity in rodents, after controlling for correlations with body mass. Body mass, mass‐corrected RMT, maximum urine concentration, (scored on a semiquantitative scale of 1–4 indicate increasing aridity) all showed statistically significant phylogenetic signal. varied significantly among habitats, main difference being aquatic species larger than those from other habitats. Mass‐corrected RMT concentration positive correlation ( \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{...
