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.

The sensory basis of rheotaxis in the blind Mexican cave fish, Astyanax fasciatus

TL;DR: It is demonstrated that the superficial lateral line system controls rheotaxis at low current velocities, providing a clear behavioral role for the superficial neuromasts where none previously existed and establishing a link between the mechanosensory lateral line and olfactory systems in the Olfactory search behavior of the cave fish.

Segregation Models for Disomic, Tetrasomic and Intermediate Inheritance in Tetraploids: A General Procedure Applied to Rorippa (Yellow Cress) Microsatellite Data

TL;DR: A simple likelihood-based approach that is able to incorporate disomic, tetrasomic, and intermediate inheritance models and estimates the double-reduction rate is presented and shows that inheritance of microsatellite markers in natural tetraploids of Rorippa amphibia and R. sylvestris is tetrasome, confirming their autotetraploid origin.

Paternal care and egg survival both increase with clutch size in the fathead minnow, Pimephales promelas

TL;DR: The effects of clutch size on paternal care and egg survival in the fathead minnow, Pimephales promelas, are examined and it is found that both increased with male clutch size.

Environment-dependent use of mate choice cues in sticklebacks

TL;DR: If increased phytoplankton turbidity influences the relative use of olfactory and visual cues in mate choice in the three-spined stickleback Gasterosteus aculeatus is determined.

Effective population size of steelhead trout: influence of variance in reproductive success, hatchery programs, and genetic compensation between life‐history forms

TL;DR: In this article, the authors used demographic data and genetic parentage analysis on an almost complete sample of all adults that returned to the river over 15 years (> 15 000 individuals), and estimated the effective number of breeders per year and effective population size per generation (N e ) in anadromous steelhead trout (Oncorhynchus mykiss) in the Hood River, Oregon (USA).
