Is there a link between people's heart rate and blood pressure? Does the lead in petrol fumes affect the growth of roadside plants? The ability to expertly analyse statistical data is a crucial skill in the biological sciences - it is fundamental to fully understanding what your experiments are actually telling you and so being able to answer your research questions. Statistical and Data Handling Skills in Biology gives you everything you need to understand and use statistical tests within your studies and future independent research. Written in a straight-forward and easy to understand style it presents all of the tests you will need throughout your studies, and shows you how to select the right tests to get the most out of your experiments. All of this is done in the context of biological examples so you can see just how relevant a skill this is, and how becoming fully proficient will make you a more rounded scientist. This 4th edition has been thoroughly updated throughout and now includes detailed coverage of the free statistical package R studio and a new chapter on how to write about and present statistics in papers, theses and reports. The first chapter has also been revised to introduce students to the need for and ideas behind statistical analysis. Features * Clear explanation with step by step detail of how to carry out a wide range of statistical analyses will help you to quickly gain understanding and confidence in this essential area. * Useful decision charts will help you to select the right statistical test and gain confidence in answering your research questions. * Real world examples in each chapter will help you to develop an applied understanding of the full range of statistical techniques * Self-assessment problems scenarios at the end of each chapter enable you to practice applying your understanding of a technique, thereby improving your confidence in using numbers. Guided answers allow you to check your understanding. Statistical and Data Handling Skills in Biology 4th edition is ideal for any biomedic or environmental scientist getting to grips with statistical analysis for use in class on as part of independent study.

Get submerged in the amazing world of sharks! Your expert host, award-winning marine biologist Dr. David Shiffman, will show you how-and why-we should protect these mysterious, misunderstood guardians of the ocean. Sharks are some of the most fascinating, most ecologically important, most threatened, and most misunderstood animals on Earth. More often feared than revered, their role as predators of the deep have earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us-they're in danger from us. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman explains why it's crucial that we overcome our misconceptions and rise above cinematic jump scares to embrace sharks as the imperiled and elegant ocean guardians they really are. Sharing his own fascinating experiences working with sharks, Shiffman tells us * why healthy shark populations are a must for supporting ocean ecosystems-and the coastal economies that depend on them * why we're in danger of losing many shark species forever * what scientists, conservationists, and readers can do to help save these iconic predators * why so much of what you've heard about sharks and how to save them is wrong Exploring the core tenets of shark conservation science and policy, Shiffman synthesizes decades of scientific research and policymaking, weaving it into a narrative full of humor and adventure. Touching on everything from Shark Week to shark fin soup, overfishing to marine sanctuaries, Shiffman reveals why sharks are in trouble, why we should care, and how we can save them. Perfect for shark enthusiasts, Why Sharks Matter is an approachable, informative guide to the world of shark conservation and the passionate, fascinating, brilliant people who work to understand and protect our oceans. This fun read will have you looking at sharks with a fresh perspective and an understanding that the survival of sharks is crucial to the survival of another apex predator-ourselves.
