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

Effect of lipid and n−3 HUFA levels in microdiets on growth, survival and fatty acid composition of larval gilthead seabream (Sparus aurata)
M. Salhi,Marisol Izquierdo,Carmen María Hernández-Cruz,M. González,Hipólito Fernández-Palacios +4 more
TL;DR: Results showed that for the lipid levels tested, the larval n −3 HUFA requirement did not decrease as the lipid level in the diet decreased, and the larvae supported the best survival rates regardless of their lipid content.

Demographic consequences of drought in the herbaceous perennial Cryptantha flava: effects of density, associations with shrubs, and plant size
TL;DR: Despite severe demographic consequences of drought, the study provided no evidence that intraspecific competition, interference by shrub, or facilitation by shrubs increases under limited soil water.

Polarizing Microscopy Identification of Chemical Diagenesis in Archaeological Cementum
TL;DR: In this article, the authors present a new application to archaeological ungulate cementum of a polarizing microscopy technique that has previously been utilized to identify the effects of chemical diagenesis in archaeological bone and human cementum (Geusa et al., 1999; Gilbert, 1989; Watson, 1975; Zeder, 1978).

Does size really matter? Effects of fish surface area on the settlement and initial survival of Lepeophtheirus salmonis, an ectoparasite of Atlantic salmon Salmo salar.
TL;DR: Insight is provided into the effects of the amount of host surface area available on parasite settlement and survival, and the potentially increased susceptibility of farmed salmon smolts to infection of this ectoparasite is highlighted.

Genetic variation in constitutive and inducible pyrrolizidine alkaloid levels inCynoglossum officinale L.
Nicole M. van Dam,Klaas Vrieling +1 more
TL;DR: It is concluded that changes in PA distribution over the plant resulted from transport of PAs within the plant, and that damage-induced defences in Cynoglossum officinale do not play an important role.
