Biometry: the principles and practice of statistics in biological research 2nd edition.
TLDR
The book aims to instill in students an ability to think through biological research problems in such a way as to grasp the essentials of the experimental or analytical setup to know which types of statistical tests to apply in a given case and to carry out the computations required.Abstract:
This text develops the science of biometry from an elementary introduction up to the advanced methods necessary for biological research and for an understanding of the published literature. This text is aimed primarily at the academic biologist including general zoologists botanists microbiologists geneticists and physiologists in universities research institutes and museums. This book while furnishing ample directions for the analysis of experimental works also stresses the descriptive and analytical statistical study of biological phenomena. It is intended both as a text to accompany a lecture course and as a complete course for self-study. The book aims to instill in students an ability to think through biological research problems in such a way as to grasp the essentials of the experimental or analytical setup to know which types of statistical tests to apply in a given case and to carry out the computations required. Chapters cover biological data data handling descriptive statistics probability estimation and hupothesis testing analysis of variance linear regression correlation multiple and curvilinear regression analysis of frequencies and miscellaneous methods.read more

The Case for an Internal Dynamics Model versus Equilibrium Point Control in Human Movement
TL;DR: It was found that the subjects stopped short of the target on the trials where the magnitude of the assistance was randomly decreased, compared to the preceding control trials, contrary to the EPH, which predicts that final position should not be affected by external loads that depend purely on velocity.

Plant traits, litter quality and decomposition in a Mediterranean old-field succession
TL;DR: Community functional parameters were tightly linked to initial litter N concentration, and thereby to litter decay and N loss rates, and the strongest correlations were found with leaf dry matter content, which therefore appears as a powerful marker of litter properties.

Incest avoidance, fluctuating asymmetry, and the consequences of inbreeding in Iridomyrmex humilis, an ant with multiple queen colonies
Laurent Keller,Luc Passera +1 more
TL;DR: The influence of kinship on mating preferences was investigated in a polygynous ant species, Iridomyrmex humilis, which has within-nest mating and it is suggested that even if inbreeding effects on colony productivity are absent or low, incest avoidance mechanisms may have evolved and been maintainedif inbreeding queens produce a higher proportion of unviable offspring.

Effects of Single-Dose Ultraviolet Radiation on Skin Superoxide Dismutase, Catalase, and Xanthine Oxidase in Hairless Mice
Barbara C. Pence,Mark F Naylor +1 more
TL;DR: In this paper, the effects of a single exposure to UVB radiation on skin antioxidant enzymes and superoxide-generating xanthine oxidase were examined in Skh:HR-1 hairless mice.

Dance dialects and foraging range in three Asian honey bee species
Fred C. Dyer,Thomas D. Seeley +1 more
TL;DR: The hypothesis that a colony's dialect is adaptively “tuned” to enhance efficiency of communication over the distances that its foragers typically fly is examined, but there are no striking dialect differences among the Asian bees in Thailand.
