For the first time, here is a practical guide to marine plankton as seen and collected from the seashore. Perfect for naturalists and ecologists, amateur or professional alike, this book accesses a captivating hidden world. Illustrated throughout with stunning photographs, the multitudes of microscopic life-forms typically found in seawater that laps the shore are displayed, discussed and interpreted.The first section explains what exactly plankton is and sets out the practicalities of shore collection. We are guided through where and how to do this, observing samples and the basics of using microscopes not only to view but also to photograph the creatures. The second section, comprising the bulk of the book, then takes us into the living organisms we are likely to find: from diatoms, dinoflagellates and even fungi, through single-celled organisms to the huge array of invertebrates and chordates. The concluding third section offers a holistic view, considering ecology and the importance of understanding planktonic life while underlining the problems caused by human activity.Readers will learn: - The biology of plankton, including lifecycle, seashore and estuarine habitats, as well as classification. - Shore-based collection skills and processes: observing marine plankton, including via digital microscopes and optical microscopes, how to sort and view samples. - Microscopic photography techniques. - How to organise and sort samples, including systematics, classification and terminology. - Identification of planktonic organisms by group. - Details of the wider marine planktonic environment, including vertical migration, food webs and nutrient cycles. - The interactions of plankton and humans, including microplastics, eutrophication and climate change.Overall this exciting book is an essential tool for any seashore enthusiast.

An engaging account of the natural history of rock and boulder-strewn shores around Britain's coastline. 'As packed with knowledge and enthusiasm as a rock pool is filled with strange and beautiful species' Maya Plass, BBC Wildlife Rocky Shores explores the species, communities and landscape of the narrow strip of land surrounding much of the British Isles. While it may be limited in breadth, this habitat is incredibly biodiverse, and this insightful book details all the patterns of marine life that might be encountered on sheltered and exposed shores, from the inhospitable splash zone to the repeatedly submerged lower shore, and everything in between.Comprehensive chapters accompanied by exceptional photographs cover various members of the rocky-shore community in turn: striking lichens that colourfully adorn the rocks; seaweeds that have sustained human settlements for millennia; mysterious and often spectacular worms and their relatives; molluscs with variously configured shells; spiny-skinned echinoderms that move using tube feet; arthropods that range from tiny marine insects to heavy-clawed crabs; and microscopic species that drift around at the mercy of the tides. Rock pools provide pockets of diversity dotted across the shore, while the strandline at the high-tide mark supports a unique assemblage of microbes and invertebrates that attracts a variety of birds and mammals.For anyone with a love of the shore – from the occasional rockpooler to avid naturalists – this book is a must-have for your collection.

Time and circumstance often prevent the perfect photograph from being taken. This book explains how to enhance an image using readily available software in order to obtain the photo you wanted to take. It explains how to analyse a photograph to recognize what needs to be done, and then shows how to improve it. Instead of being a guide to one specific software program, the book looks at different styles of workflow and process. It covers transferable skills and uses a variety of software for all budgets. Written with accessible clarity and practical detail, this book is a must for everyone who enjoys their photography and wants to take their images to the next level. Topics covered include: the digital image and the terms used, from pixels to histograms; software to suit all budgets, from the best of the free programs to the most expensive; downloading, organizing and viewing images; the essential elements of the image (how it was exposed, the tonal range, noise and sharpness) and finally, further options such as (composition, monochrome, colour palette and cloning tools). Examples of real photos and problems are given, along with step-by-step guides to how they can be rectified. It is a must for everyone who enjoys their photography and will be of great interest to biologists, naturalists, scientists and natural historians as well. It is superbly illustrated with 218 colour photos. Julian Cremona is a passionate photographer who specializes in extreme close-up photography and focus stacking.

This practical book explains what is meant by macro photography and how to get even closer to your subject: not just a close-up of a butterfly, but details of the eye and wing scales. Techniques suited to any budget look at ways to photograph virtually any creature, whether terrestrial, marine or from freshwater. All the key elements to achieve extreme close-ups are built in a clear way, for both outdoor and studio use, and special attention is given to focus stacking, with both software and further enhancements covered.

Seashores - An Ecological Guide provides an easy-to-use, authoritative reference to commonly occurring organisms. By looking at the habitats of the coastline, it focuses on key species you are likely to find. The book explains how these organisms have adapted and how they are able to cope with the environmental stresses of the seashore. With over 400 colour photographs, the guide looks first at the physical and biological features that determine our coast before surveying the variety of communities that exist on our shores. These include: rocky shores; sand and mud; estuaries; salt-marsh; sand dunes; shingle and plankton.
