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.

Early reproduction and increased reproductive allocation in metal-adapted populations of the terrestrial isopod Porcellio scaber.

TL;DR: It is concluded that the isopods at the metal-contaminated sites have been selected for early reproduction and increased reproductive allocation, indicating that populations inhabiting metal-polluted sites have probably undergone evolutionary changes.

Genetic differentiation of Texas Gulf Coast populations of the blue crab Callinectes sapidus

TL;DR: The spatial heterogeneity in allelic frequencies suggests that interpopulation gene flow is not sufficient to overcome population differentiation resulting from genetic drift and/or natural selection and seasonal changes in larval source populations may result from population differences in spawning season or developmental times.

The relationship between foraging behaviour and energy expenditure in Antarctic fur seals

TL;DR: There is no apparent energetic advantage for females in undertaking foraging trips of any particular duration within the range of conditions observed.

Spatial pattern quantification of Antarctic benthic communities using landscape indices

TL;DR: In this paper, the spatial patterns in an Antartcic benthic assemblage across different stations based on landscape indices were investigated, and the optimal subset of indices was chosen for describing Antarctic benthical patterns.

Gamete production, somatic growth and multiple-locus enzyme heterozygosity inMytilus edulis

TL;DR: It is concluded that the higher scope for growth of more heterozygous bivalves is translated into allocation of energy to somatic growth during early life and into gamete production in later life, which may explain why the correlation between growth rate and heterozygosity in bivalve is manifested most clearly when young individuals are examined.
