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

Secondary succession in an experimentally fragmented landscape: community patterns across space and time
TL;DR: In this article, the authors describe patterns of succession over 18 years in an experimentally fragmented landscape created in eastern Kansas, USA, in 1984, and the design of the experiment permits one to assess the influence of patch size and landscape position on successional dynamics.

Ovarian hyperandrogenism in adult female rhesus monkeys exposed to prenatal androgen excess
TL;DR: Prenatal androgen excess in female rhesus monkeys causes perturbations in ovarian and adrenal steroidogenesis during adulthood, which may both contribute to hyperandrogenism.

The spectre of 'spurious' correlations.
TL;DR: It is shown that ratios and indices often provide surprising and 'spurious' results due to their unusual properties, and advocate the use of randomization tests to evaluate hypotheses confounded by ‘spurious’ correlations.

Post-dispersal predation and scatterhoarding of Dipteryx panamensis (Papilionaceae) seeds by rodents in Panama
TL;DR: Low survival of scatterhoarded seeds suggests that the alternative food supply over the animal's home-ranges in May–June 1990 was too low to promote survival of cached seeds.

Control of plant growth by nitrogen and phosphorus in mesotrophic fens.
TL;DR: In this article, a mesotrophic fens experiment was carried out to investigate whether plant growth in these systems is controlled by the availability of N, P or K. The fens are located in an area with high N inputs from precipitation and are annually mown in the summer to prevent succession to woodland.
