Download or read book Sea Squirts and Sea Sponges of Britain and Ireland written by Sarah Bowen and published by Princeton University Press. This book was released on 2018-07-09 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea squirts and sponges are found in most seafloor habitats around the coasts of Britain and Ireland. Despite being the dominant life forms in many areas, these two groups of under-recorded marine animals are often confused with one another, and most divers and snorkellers can recognise and name very few species. In fact, around 500 species of Ascidiacea (sea squirts) and Porifera (sponges) have been described so far in British and Irish seas, corresponding to over 4% of the world’s total. This book is recommended reading for anyone who wants to identify and discover more about these fascinating and diverse animals. Rather than relying on the characteristics of preserved specimens, this guide uses marine photography and detailed underwater observations to concentrate on in situ features, allowing you to record species without collecting them. Most sea squirts found in Britain and Ireland’s shallow waters are included, together with the most easily recognised sponges. Whether you are a student, a diver, a rockpooler or simply an enthusiast, this is an essential companion. ● Over 115 species described in detail with in situ photographs to help with underwater recognition ● Information on size, depth, habitat and distribution ● Key distinguishing features and areas of confusion in identification highlighted ● Details of body structure, life histories, digestive and reproductive processes ● Information about predators, interactions between species, non-native and problem invasive species

Download or read book Animals and Psychedelics written by Giorgio Samorini and published by Simon and Schuster. This book was released on 2002-08-01 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Italian ethnobotanist explores the remarkable propensity of wild animals to seek out and use psychoactive substances. • Throws out behaviorist theories that claim animals have no consciousness. • Offers a completely new understanding of the role psychedelics play in the development of consciousness in all species. • Reveals drug use to be a natural instinct. From caffeine-dependent goats to nectar addicted ants, the animal kingdom offers amazing examples of wild animals and insects seeking out and consuming the psychoactive substances in their environments. Author Giorgio Samorini explores this little-known phenomenon and suggests that, far from being confined to humans, the desire to experience altered states of consciousness is a natural drive shared by all living beings and that animals engage in these behaviors deliberately. Rejecting the Western cultural assumption that using drugs is a negative action or the result of an illness, Samorini opens our eyes to the possibility that beings who consume psychedelics--whether humans or animals--contribute to the evolution of their species by creating entirely new patterns of behavior that eventually will be adopted by other members of that species. The author's fascinating accounts of mushroom-loving reindeer, intoxicated birds, and drunken elephants ensure that readers will never view the animal world in quite the same way again.
Download or read book Nature Obscura written by Kelly Brenner and published by Mountaineers Books. This book was released on 2020-02-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: With wonder and a sense of humor, Nature Obscura author Kelly Brenner aims to help us rediscover our connection to the natural world that is just outside our front door--we just need to know where to look. Through explorations of a rich and varied urban landscape, Brenner reveals the complex micro-habitats and surprising nature found in the middle of a city. In her hometown of Seattle, which has plowed down hills, cut through the land to connect fresh- and saltwater, and paved over much of the rest, she exposes a diverse range of strange and unknown creatures. From shore to wetland, forest to neighborhood park, and graveyard to backyard, Brenner uncovers how our land alterations have impacted nature, for good and bad, through the wildlife and plants that live alongside us, often unseen. These stories meld together, in the same way our ecosystems, species, and human history are interconnected across the urban environment.
Download or read book I of the Vortex written by Rodolfo R. Llinas and published by MIT Press. This book was released on 2002-02-22 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: A highly original theory of how the mind-brain works, based on the author's study of single neuronal cells. In I of the Vortex, Rodolfo Llinas, a founding father of modern brain science, presents an original view of the evolution and nature of mind. According to Llinas, the "mindness state" evolved to allow predictive interactions between mobile creatures and their environment. He illustrates the early evolution of mind through a primitive animal called the "sea squirt." The mobile larval form has a brainlike ganglion that receives sensory information about the surrounding environment. As an adult, the sea squirt attaches itself to a stationary object and then digests most of its own brain. This suggests that the nervous system evolved to allow active movement in animals. To move through the environment safely, a creature must anticipate the outcome of each movement on the basis of incoming sensory data. Thus the capacity to predict is most likely the ultimate brain function. One could even say that Self is the centralization of prediction. At the heart of Llinas's theory is the concept of oscillation. Many neurons possess electrical activity, manifested as oscillating variations in the minute voltages across the cell membrane. On the crests of these oscillations occur larger electrical events that are the basis for neuron-to-neuron communication. Like cicadas chirping in unison, a group of neurons oscillating in phase can resonate with a distant group of neurons. This simultaneity of neuronal activity is the neurobiological root of cognition. Although the internal state that we call the mind is guided by the senses, it is also generated by the oscillations within the brain. Thus, in a certain sense, one could say that reality is not all "out there," but is a kind of virtual reality.
Download or read book Beyond the Sea Squirt written by Moira Dempsey and published by . This book was released on 2019-05-17 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the most fundamental level the only reason we have a brain is because we move. To develop the ability to feel and think actually requires movement as a first step. Sea squirts illustrate this well. Sea squirt larvae have a very rudimentary brain and nervous system. However, they have no mouth or way to feed. The larvae are able to move to the sea floor where they cement themselves head first and this is where they will stay. As the sea squirt will never move from that spot it no longer needs its brain and nervous system so it starts absorbing it. This absorption gives the larvae enough nutrients to be able to build the circulatory, digestive and reproductive systems necessary to sustain its existence.It is because we move that we develop a brain that, eventually, is able to perform very complex tasks. It is the primitive reflex programme that provides the initial stimulus to develop the movement patterns that ultimately become our ability to move with coordination, ease and grace against gravity. It is movement that grows the brain that lays the foundation to understand the world. It is movement that develops the neurology that allows us to be creative, think, solve problems, control impulses and connect to others. It is movement that provides us with the ability to manipulate tools and develop technology. It is movement that takes us Beyond the Sea Squirt.RMTi follows a drug free approach to postural, learning, sensory, emotional and behavioural challenges. It does this by using movements and activities that replicate the innate movements made by a developing foetus and infant that are necessary to integrate primitive reflexes, establish life-long movement patterns, grow the brain, develop head control and muscle tone.Beyond the Sea Squirt is for those interested in RMTi and the stories of some of those who have used the programme to make beneficial changes.

Download or read book Mind in Motion written by Barbara Tversky and published by Basic Books. This book was released on 2019-05-21 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: An eminent psychologist offers a major new theory of human cognition: movement, not language, is the foundation of thought When we try to think about how we think, we can't help but think of words. Indeed, some have called language the stuff of thought. But pictures are remembered far better than words, and describing faces, scenes, and events defies words. Anytime you take a shortcut or play chess or basketball or rearrange your furniture in your mind, you've done something remarkable: abstract thinking without words. In Mind in Motion, psychologist Barbara Tversky shows that spatial cognition isn't just a peripheral aspect of thought, but its very foundation, enabling us to draw meaning from our bodies and their actions in the world. Our actions in real space get turned into mental actions on thought, often spouting spontaneously from our bodies as gestures. Spatial thinking underlies creating and using maps, assembling furniture, devising football strategies, designing airports, understanding the flow of people, traffic, water, and ideas. Spatial thinking even underlies the structure and meaning of language: why we say we push ideas forward or tear them apart, why we're feeling up or have grown far apart. Like Thinking, Fast and Slow before it, Mind in Motion gives us a new way to think about how--and where--thinking takes place.
Download or read book Weird Sea Creatures written by Erich Hoyt and published by Firefly Books. This book was released on 2015-03-05 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: An illustrated look at the weird and wonderful creatures that live in the very deepest parts of the sea. Humans have always wondered, with a mixture of fear and fascination, what lurks beneath the surface in the depths of the ocean. In this book, Erich Hoyt introduces 50 of the oddest creatures you will ever meet in the sea. From the carnivorous comb jelly to the lantern-carrying deep-sea dragonfish, from a vampire squid with giant eyes to dancing jellyfish, Hoyt explores these peculiar conditions and their equally peculiar environment. These creatures have adapted to lack of light and, using sound pulses (echolocation) or light-producing organs and pigment cells (emitting light via bioluminescence), they are able to communicate without giving their location away to predators. These stunning, captivating photographs weren't taken from the portholes of submarines. Photographers David Shale, Solvin Zanki and Jeff Rotman worked with oceanography institutes, museums and the BBC Natural History Unit, taking long cruises across the ocean to record and try to understand these little-studied residents of the deep sea. To capture the creatures for observation, a net was lowered far beneath the surface. As soon as the trawl was hauled aboard, the photographers would race to transfer the most unusual animals to fresh seawater aquariums in a chilled laboratory on board. These pages let readers gaze into strange, wild eyes and study faces with toothless or crooked smiles that witness the fruits of deep-sea evolution. Informative captions explain what the patterns of lights on their bodies are "saying" to others in their absolutely dark world. The wonder and extraordinary weirdness of what lives in the deep seas, so far away from us and yet so close, will become more familiar with this book.

Book excerpt: Steller's classic work, published in Latin in 1751 and in German in 1753, contains the only scientific description from life of the Steller's sea cow (Hydrodamalis gigas), as well as the first scientific descriptions of the fur seal or "sea bear" (Callorhinus ursinus), Steller's sea lion (Eumetopias jubatus), and the sea otter (Enhydra lutris). Steller's sea cow was a sirenian, or manatee, inhabiting the North Pacific Ocean and Bering Sea. It was first discovered by Europeans in 1741 and rendered extinct by 1768. It was a 30-foot long, plant-eating aquatic mammal, weighing up to 12 tons, that lived in large herds on the coasts of Alaska and Kamchatka. Steller made his observations as part of Vitus Bering's second voyage, during which the crew was shipwrecked for 9 months on Bering Island, from November 1741 to August 1742.
