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

Defoliation increases carbon limitation in ectomycorrhizal symbiosis of Betula pubescens
TL;DR: The present results support the prediction that the plant investment in ectomycorrhizae may decline as a response to foliage loss, and the colonization percentage of thick-mantled mycorrhIZae in the roots, the most marked decline occurring in the repeatedly defoliated seedlings.

Aerobic metabolic rates of swimming juvenile mako sharks, Isurus oxyrinchus
TL;DR: The findings suggest that the estimate of SMR for juvenile makos is comparable to that recorded for other similar-sized, ram-ventilating shark species (when corrected for differences in experimental temperature), however, the mako RMR and MMR are apparently among the highest measured for any shark species.

Astaxanthin production by Phaffia rhodozyma and Haematococcus pluvialis: a comparative study.
TL;DR: The main aim of this work was to examine how astaxanthin synthesis, by P. rhodozyma and H. pluvialis, could be compared, based on previous works by the authors where pigment productions have been reported.

The time course of spatial memory distortions.
Steffen Werner,Jörn Diedrichsen +1 more
TL;DR: In all but one experiment, the distortion increased with longer retention intervals, which might reflect the almost immediate decay of detailed spatial information and the early influence of an enduring spatial memory representation, which encodes spatial information in terms of the perceived structure of space.

Sexually selected male plumage color is testosterone dependent in a tropical passerine bird, the red-backed fairy-wren (malurus melanocephalus)
TL;DR: It is shown that testosterone is the primary mechanism functioning during the pre-nuptial molt to regulate intrasexually variable plumage color and breeding phenotype in male red-backed fairy-wrens and that the role of T in mediating plumage signal production may differ across age classes, plumage patches, and between pigment-types.
