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.

Scrounging prevents cultural transmission of food-finding behaviour in pigeons

TL;DR: This article showed that pigeons who shared the food discoveries of others (scroungers) did not learn the food-finding technique used by the discoverers (producers).

The effect of ocean acidification on symbiont photorespiration and productivity in Acropora formosa

TL;DR: Findings support an important functional role for PGPase in dinoflagellates that is potentially compromised under CO(2) enrichment and enhance photoacclimation to the subsaturating light levels.

Effects of patterned electrical activity on neurite outgrowth from mouse sensory neurons

TL;DR: Cessation of neurite outgrowth by action potentials could represent one mechanism linking morphological and functional characteristics in the developing CNS of mammals, by stabilizing the outgrowth of neurites forming appropriate synaptic contacts and leading to the retraction of growth cones from collaterals that have not formed appropriate contacts at the time the neuron enters into a functionally active circuit.

Salt stress limitation of seedling recruitment in a salt marsh plant community.

TL;DR: The results show that seedling recruitment by high marsh perennial turfs is limited by high soil salinities and that consequently their population dynamics are determined primarily by clonal growth processes.

Improvements in methods for calculating virus titer estimates from TCID50 and plaque assays

TL;DR: Two different weighted linear regression methods to determine TCID50 and PFU titers from CPE assays make use of a generalized least squares approach using continuous colorimetric data, improvements in titer and error estimation compared to simpler calculation methods.
