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

Pitcher dimorphism, prey composition and the mechanisms of prey attraction in the pitcher plant Nepenthes rafflesiana in Borneo.
TL;DR: The combination of visual and olfactory cues accounted for the greater prey attraction of upper over lower pitchers and may reduce the amount of prey caught, thus preventing overloading and consequent putrefaction of the contents, and death of the pitchers.

Socioecological transitions trigger fire regime shifts and modulate fire–climate interactions in the Sierra Nevada, USA, 1600–2015 CE
TL;DR: A 415-y record of fire activity was developed by merging a tree-ring–based record of Sierra Nevada fire history with a 20th-century record based on annual area burned to show large fire regime shifts during the past 415 y corresponded with socioecological change, and not climate variability.

Ability of static and statistical mechanics posturographic measures to distinguish between age and fall risk.
TL;DR: The statistical mechanics techniques appear to have some advantages over traditional posturographic measures for studying balance control, including detecting significant differences between the young and older "low-risk" groups, while none of the traditional measures were significantly different.

Natural selection and cultural rates of change.
TL;DR: Using functional and symbolic design features for Polynesian canoes, it is shown that natural selection apparently slows the evolution of functional structures, whereas symbolic designs differentiate more rapidly, indicating that cultural change can follow theoretically derived patterns.

TL;DR: All-cause and ASCVD mortality rates in DP and in the GP were significantly correlated; the relationship became even stronger after adjustment for age (R(2) = 0.56, P < 0.0001); a substantial portion of the variability in mortality rates that were observed across DP worldwide is attributable to the variability of background ASCVD deaths in the respective GP.
