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

Journal ArticleDOI
Interpopulation variation in the risk-related decisions of Portia labiata, an araneophagic jumping spider (Araneae, Salticidae), during predatory sequences with spitting spiders.
TL;DR: Questions concerning limitations on how intricate the decision-making processes might be in arthropods are raised, as Scytodes pallidus is a spitting spider that specialises in preying on jumping spiders, and Portia labiata is a jumping spider that preys on S. Pallidus.

Signatures of random and selective mass extinctions in phylogenetic tree balance.
Stephen B. Heard,Arne Ø. Mooers +1 more
TL;DR: A simple simulation model is reported on that includes heritable and evolving speciation rates coupled with mass extinctions, showing that random mass extinction are plausible contributors to the imbalance of modern clades.

Reexamining the relationship between body size and tonal signals frequency in whales: a comparative approach using a novel phylogeny
TL;DR: This work generates the most complete species level cetacean phylogeny to date, which is then used to reconstruct the evolutionary history of body size and standard tonal sounds parameters (minimum, maximum, and center frequency).

A general model of metapopulation dynamics
TL;DR: It is shown that the models of Levins, Hanski, and Gotelli are extreme cases of a single metapopulation model, which predicts the equilibrium fraction of sites occupied as a function of 4 parameters, 2 for colonization and 2 for extinction.
