    Book: Microscopy as a Hobby

    A good beginner level book

    Mol Smith’s book, published in 2014 presents “a 21st Century Quick Start Guide” that will bring anyone easily into the microscope hobby. Mol Smith, the editor of Micscape Magazine by its editor Mol Smith is an acknowledged world authority on the use of the amateur microscope.

    Most introductory books are decades old but this one gives the information for parents, teenagers or mature adults needed to get started (or restarted). This is now a high tech activity that rivals the excitement of any modern interest group and the tools needed have become very accessible. It is really useful for a micro-naturalist.

    The book recommends safe-to-use chemicals, and easily obtainable equipment that allows anyone to learn to access the hidden and unseen world under a microscope.

    Publisher Information

    This little book (142 pages) gives everything you need to know to get going. I own it, and I recommend it to you. Available online ISBN: 9781500301651 printed at Middletown DE USA.

    Diatoms

    Good Reference Book on Diatoms

    This is a good starter reference book to diatoms. They are tiny creatures that can be easily seen under the microscope. Its fun to see them but much more rewarding to be able to identify them. I capture my samples with a plankton net.

    Diatoms are excellent subjects for study by amateurs under the microscope. They occur in lots of locations so besides being beautiful they are easily found in marine and freshwater settings. Diatoms are recognizable by their silca-based ‘shells’ called frustules.These are in two halves, and contain the living organism.

    A good guide to diatoms is William Vinyard’s book which is available from online book dealers. This book will bring pleasure to the viewing of diatoms because it gives an easily followed identification index. It also provides lots of background on the biology of diatoms.

    Foraminifera

    Protists With Shells

    Foraminifera are simple organisms which, when alive, protrude pseudopodia through tiny pores in a rigid calcareous test or shell. This shell can be a single chamber or can be composed of multiple chambers. Most are marine, and can be either bottom-dwelling or floating plankton.

    The accumulations of their dead shells become part of the sediment column on the bottom of the ocean. Under the microscope these shells are intricate and beautiful. They tell the story of the conditions under which they lived. They are not easy to locate in our area – but turn up as micro-fossils in sediment on the sea floor.

    The shells are particularly beautiful and intricate. Each species can be identified from particular features produced in this structure. Mainly marine, both benthic (bottom dwelling) and planktonic (floating in the water column). They are little known to amateur micro-naturalists. Once they are discovered, they create a fascination which is hard to shake.

    Marine Plankton Under the Microscope

    Study Plankton under a microscope

    Close proximity to the sea provides many opportunities for the Micro-Naturalist to enjoy endless viewing of spectacular subjects. Plankton is one of those topics.

    How to do it?

    I use a small student-grade plankton net launched by hand from the shore on a line to gather samples. I view them while the subjects are still fresh. By capturing images of the most interesting subjects I was able to research and identify the organisms from reference texts.

    Where to get them?

    The waters around Vancouver Island BC are easy sources of phytoplankton and zooplankton. With very little effort you can get fantastic forms of microscopic life into view. Even the sand is worth studying. But you could find them in a lake, a pond or pool.

    The variety and quantity of organisms is different each time. There are examples of both phytoplankton and zooplankton in the samples. Care in handling the raw sample ensures that few of the organisms are damaged and of course only a small drop of water from the sample is examined at any one time (so the sample does not need to be very large).

    Identification of Organisms

    I refer organisms that I cannot identify to the Amateur Microscopy Facebook group where experts assist with identification down to the genus, and sometimes even to the species level. By keeping a lab notebook I keep records of the organisms I encounter, and make notes when they are identified. This provides a reference for later use when examples of the organisms are encountered again.

    Amateur Microscope Users Network on Vancouver Island

    Building a Network of Amateur Micr-Naturalists

    Linking up other like-minded amateur users of microscopes is a major goal of this website. Scattered the length of Vancouver Island are amateur microscopists working alone on their hobby. Imagine an informal network linking us all up together – and even hosting periodic coffee meet ups where we can all get to know each other. Maybe some day we will host a technical meeting – with speakers – its possible!

    What Is a Micro-Naturalist?

    A micronaturalist is simply a naturalist who is interested in using a microscope to access the small world that forms the basis of all life. “Take a field trip without leaving the room with a microscope” is our tagline.

    The idea is to learn from each other, trade information, and even build friendships that generate projects. We could, as a group, create useful tools for others based on the knowledge we are accumulating. I’d like to think that we are going to inspire others to join us in this activity.

    Meet Up with Us

    If you are interested in linking up with us – please send a message to microscope (at) shaw.ca expressing an interest. We are a friendly, respectful, supportive and positive group who would like to include anyone interested in microscopy.
