The Early Development of PlanorbIs: A Dissertation presents a careful exploration of mollusk embryology. This book details how Planorbis trivolvis eggs begin their life, how cleavage proceeds, and how the early mesoblast and nervous system structures form. It also explains the staining and mounting techniques used to trace cell lineages, making complex development visible and understandable.

How the egg divides in the early stages and how the first and second cleavages lay out the body plan
How researchers trace cell lineages using staining methods and what kinds of observations those stains reveal
The origin and timing of the secondary mesoblast and its relation to larval structures
Descriptive details of gastrulation and the formation of key organs in the developing planorbids

Ideal for readers of biology, embryology, and mollusk development who want a clear, historical perspective on early developmental processes.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free.
