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

Quantifying the impact of longline fisheries on adult survival in the black‐footed albatross
Sophie Véran,Olivier Gimenez,Olivier Gimenez,Elizabeth Flint,William L. Kendall,Paul F. Doherty,Jean-Dominique Lebreton +6 more
TL;DR: In this paper, a general framework for quantifying the relationship between albatross population and longline fishing in absence of reliable estimates of bycatch rate was presented, and the average survival for 1997-2002 was 92%, a low value compared to estimates available for other albross species.

Morphology of renal afferent arterioles in spontaneously hypertensive rats.
TL;DR: The lumen reduction in renal afferent arterioles in spontaneously hypertensive rats is not the result of an encroachment on the lumen by a hypertrophic media.

Preferences of Pollinators and Herbivores in Gynodioecious Geranium sylvaticum
Eija Asikainen,Pia Mutikainen +1 more
TL;DR: The data suggest that pollinator preference does not benefit females, whereas the higher floral herbivory of hermaphrodites might enhance the maintenance of females in G. sylvaticum, and suggest that these contributions may vary across populations and that they may function in opposite directions.

Floral resource availability and hummingbird territorial behaviour on a Neotropical savanna shrub
TL;DR: It is indicated that territorial intruder use visual cues (floral abundance) as indicators of resource availability in order to estimate cost–benefit of territory invasion and although territorial behaviour could limit pollen flow in patches with larger floral displays, this may be compensated by the territory invaders, which bring pollen from other patches.

Social monogamy in the shrimp Pontonia margarita , a symbiont of Pinctada mazatlanica , off the Pacific coast of Panama
TL;DR: The evolution of monogamy in symbiotic crustaceans inhabiting scarce, relatively small hosts in tropical environments where predation risk away from hosts is high was tested in the shrimp Pontonia margarita, which inhabits the pearl oyster Pinctada mazatlanica.
