Insektopedie lê die betowering en ryke verskeidenheid van die wêreld van insekte bloot. Dit deurgrond hul fassinerende gedrag en biologie – van paring en broeigedrag, metamorfose en beweging tot sig, reuk, gehoor en hul aanpassings by hitte en koue.

’n Hoofstuk oor superorganismes ondersoek die merkwaardige verskynsel van sosiale gemeenskappe; ’n ander een dek die kritieke rol wat dié diertjies speel om die fyn balans van lewe op ons planeet in stand te hou.

Die boek sluit af met ’n 60-bladsy geïllustreerde veldgids wat die meeste insekordes en hul belangrikste families beskryf. Voorheen as Inseklopedie van Suider-Afrika gepubliseer, maar die nuwe uitgawe is nou grondig hersien en herontwerp, met die nuutste inligting, ’n uitgebreide ID-seksie en ’n paar honderd nuwe foto’s.

Scotland’s plants define its landscape – from the heather moorlands of its iconic habitats to the weeds and a garden plants of its towns and cities. Plants have shaped the country’s domestic economy and culture over centuries, providing resources for agriculture and industry as well as food, drink and medicines. They have even inspired children’s games and been used as components in magical charms Drawing together traditional knowledge from archives and oral histories with the work of some of the country’s finest botanical artists, this book is a magnificent celebration of the enormous wealth of Scottish plant lore.

With its abundant, detailed photographs and straightforward text, this guide will help readers unlock the complicated world of trees.

From the familiar to the improbable, the gross to the endearing, The Modern Bestiary is a compendium of curious creatures. It includes both animals that have made headlines and those you've probably never heard of, such as skin-eating caecilians, harp sponges, or zombie worms - also known as bone-eating snot flowers. Arranged by elements (Earth, Water, Air), The Modern Bestiary contains well-known species told from new, unexpected angles (rats that drive cars; fish that communicate by passing wind), as well as stranger and lesser-known creatures, including carnivorous mice that howl at the moon, cross-dressing cuttlefish, and antechinuses - small marsupials that literally mate themselves to death. Finally, there are the 'aliens on Earth' - the incredible, the surreal, the magical - such as tardigrades, tongue-eating lice and immortal jellyfish, creatures so astonishing that they make unicorns look rather commonplace. Written by a zoologist with a flair for storytelling, this is a fascinating celebration of the animal kingdom.

A completely up-to-date introduction to the most common group of bees in Britain. Bees, for most people, mean honey or bumble bees, but in fact these social species make up only a small proportion of the species that live in Britain. Open your eyes to the so-called ‘solitary’ bees, and discover a wonderfully diverse population – miners, leafcutters, carpenters and masons – many of which can be found in your own back garden. Solitary bees come in a variety of colours and sizes, with some as large as bumblebees and some only a few millimetres long, and many are key pollinators for our crops and wildflowers. This comprehensive book will tell the story of how these bees live, reproduce and thrive: discover the numerous strategies used by male bees to find females and persuade them to mate; follow the females as they build their nests – or in the case of ‘cuckoo’ species, sneak into the nests of their neighbours – and watch as the new generation appears. Explore the interactions between flowering plants and their bee visitors, asking what the plants get from the relationship, as well as how the bees select the plants they visit, and the ingenuity required to extract pollen, nectar and other rewards. Finally, learn places where bees flourish and what can be done to encourage them and ensure they continue to pollinate our flowers and crops. Drawing on all the latest research as well as the authors’ own observations in the field, this timely New Naturalist gives a wonderful insight into the complicated lives of solitary bees, and the complexity of the behaviour and ecology of this remarkable group of insects.

Species evolve over time to become perfectly adapted to their environments, right?Well, sometimes. Consider that an elephant will not grow a seventh set of teeth, even though wearing down the sixth will condemn it to starvation; that hosts of the European cuckoo seem unable to tell that the overgrown monster in their nest is not their own chick; and that whales are fully aquatic mammals who, millions of years after first abandoning the land, still cannot breathe underwater. This book is about evolution, but not its greatest hits. Instead, it explores everything in the animal kingdom that is self-defeating, ill-made, uneconomical, or downright weird – and explains how natural selection has favoured it. In the grand struggle for survival, some surprising patterns emerge: animals are always slightly out-of-date; inefficiency tends to increase over time; predators usually lose, and parasites usually win. With equal parts humour and scientific insight, Andy Dobson is here to explain the how and why of evolution’s limits and liabilities.

'A funny and beautifully written welcome to the enigmatic, weird and wonderful world of wasps' DAVE GOULSON, author of SILENT EARTH There may be no insect with a worse reputation than the wasp, and none guarding so many undiscovered wonders. Where bees and ants have long been the darlings of the insect world, wasps are much older, cleverer and more diverse. They are the bee's evolutionary ancestors - flying 100 million years earlier - and today they are just as essential for the survival of our environment. A bee, ecologist Professor Seirian Sumner argues, is just a wasp that has forgotten how to hunt. For readers of Entangled Life, Other Minds and The Gospel of Eels, this is a book to upturn your expectations about one overlooked animal and the wider architecture of our natural world. With endless surprises, this book might teach you about the wasps that spend their entire lives sealed inside a fig, about stinging wasps, about parasitic wasps, about wasps that turn cockroaches into living zombies, about how wasps taught us to make paper. It offers up a maligned insect in all its diverse, unexpected splendour; as both predator and pollinator, the wasp is an essential pest controller worldwide. Inside their sophisticated social worlds is the best model we have for the earth's major evolutionary transitions. In their understudied biology are clues to progressing medicine, including a possible cure for cancer. The closer you look at these spurned, winged insects - both custodians and bouncers of our planet - the more you see. Their secrets have so far gone mostly untapped, but the potential of the wasp is endless.

When the famous South African fish scientist Professor JLB Smith published Old Fourlegs - The Story of the Coelacanth in 1956 he created an international sensation. After all, this 400-million-year-old fish, known only from fossil remains, was thought to have become extinct around 66 million years ago! JLB Smith’s dramatic account of the discovery of the first and second coelacanths in 1938 and 1952 turned him into a cult figure and put South African science on the world map. His book was eventually published in six English editions and translated into nine foreign languages.

Mike Bruton’s The Annotated Old Fourlegs includes a facsimile reprint of the original book, to which he has added notes and images in the margins that provide an interesting and revealing commentary on Smith’s text, as well as new introductory and explanatory chapters that bring the coelacanth story up to date.

The Arctic Charr is a fish of wild places. It is the fish that is capable of thriving in the harsh conditions found in the fresh waters of the far north where no other fish can. Its toughness in these extreme environments, its stunning beautiful colours (more usually associated with tropical fish) and the speed with which it is known to adapt to new environments, ensure that "charismatic" is used in any description of this species. Although widespread and often abundant, surprisingly little is known about Arctic Charr in 21st century Scotland. In this volume, two ecologists with a life-long passion for this species, distil what is known, and just as importantly what is not, about Scottich Arctic Charr.

Sedert die tweede druk van die tweede uitgawe in 1975 was Die siel van die mier egter slegs as ’n skaars tweedehandse eksemplaar beskikbaar. Hierdie uitgawe is verryk deur ’n inleidende besinning oor die vraag of Maeterlinck, die Belgiese Nobelpryswenner, Marais se teorie oor die termietnes as organiese eenheid oorgeneem het. Origens blyk dit uit die verskillende drukke en uitgawes hoe Afrikaans in die jare twintig van die twintigste eeu nog op weg was om ’n wetenskaplike woordeskat te vind en die addendum bevat artikels wat vandag slegs met moeite uit ou tydskrifte en koerante opgediep kan word.

From the author of The History of the World in 100 Animals, a BBC Radio Four Book of the Week, comes an inspirational new book that looks at the 100 plants that have had the greatest impact on humanity, stunningly illustrated throughout. As humans, we hold the planet in the palms of ours hands. But we still consume the energy of the sun in the form of food. The sun is available for consumption because of plants. Plants make food from the sun by the process of photosynthesis; nothing else in the world can do this. We eat plants, or we do so at second hand, by eating the eaters of plants. Plants give us food. Plants take in carbon dioxide and push out oxygen: they give us the air we breathe, direct the rain that falls and moderate the climate. Plants also give us shelter, beauty, comfort, meaning, buildings, boats, containers, musical instruments, medicines and religious symbols. We use flowers for love, we use flowers for death. The fossils of plants power our industries and our transport. Across history we have used plants to store knowledge, to kill, to fuel wars, to change our state of consciousness, to indicate our status. The first gun was a plant, we got fire from plants, we have enslaved people for the sake of plants. We humans like to see ourselves as a species that has risen above the animal kingdom, doing what we will with the world. But we couldn't live for a day without plants. Our past is all about plants, our present is all tied up with plants; and without plants there is no future. From the mighty oak to algae, from cotton to coca here are a hundred reasons why.

‘Steve Brusatte, the author of The Rise and Fall of the Dinosaurs, brings mammals out from the shadow of their more showy predecessors in a beautifully written book that . . . makes the case for them as creatures who are just as engaging as dinosaurs.’ – The Sunday Times, ‘Best Books For Summer’ 'In this terrific new book, Steve Brusatte . . . brings well-known extinct species, the sabre-toothed tigers and the woolly mammoths, thrillingly back to life' – The Times The passing of the age of the dinosaurs allowed mammals to become ascendant. But mammals have a much deeper history. They – or, more precisely, we – originated around the same time as the dinosaurs, over 200 million years ago; mammal roots lie even further back, some 325 million years. Over these immense stretches of geological time, mammals developed their trademark features: hair, keen senses of smell and hearing, big brains and sharp intelligence, fast growth and warm-blooded metabolism, a distinctive line-up of teeth (canines, incisors, premolars, molars), mammary glands that mothers use to nourish their babies with milk, qualities that have underlain their success story. Out of this long and rich evolutionary history came the mammals of today, including our own species and our closest cousins. But today’s 6,000 mammal species - the egg-laying monotremes including the platypus, marsupials such as kangaroos and koalas that raise their tiny babies in pouches, and placentals like us, who give birth to well-developed young – are simply the few survivors of a once verdant family tree, which has been pruned both by time and mass extinctions. In The Rise and Reign of the Mammals, palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and ground-breaking book, Steve Brusatte tells their – and our – story.

Armed with extraordinary new discoveries about our genes, acclaimed science writer Matt Ridley turns his attention to the nature-versus-nurture debate in a thoughtful book about the roots of human behavior.

Ridley recounts the hundred years' war between the partisans of nature and nurture to explain how this paradoxical creature, the human being, can be simultaneously free-willed and motivated by instinct and culture. With the decoding of the human genome, we now know that genes not only predetermine the broad structure of the brain, they also absorb formative experiences, react to social cues, and even run memory. They are consequences as well as causes of the will.

'This book is not just about life, but about discovery itself. It is about error and hubris, but also about wonder and the reach of science. And it is bookended with the ultimate question: How do we define the thing that defines us?' - Siddhartha Mukherjee, author of The Gene We all assume we know what life is, but the more scientists learn about the living world - from protocells to brains, from zygotes to pandemic viruses - the harder they find it to locate the edges of life, where it begins and ends. What exactly does it mean to be alive? Is a virus alive? Is a foetus? Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can't answer that question here on earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society's most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead. Life's Edge is an utterly fascinating investigation by one of the most celebrated science writers of our time. Zimmer journeys through the strange experiments that have attempted to recreate life. Literally hundreds of definitions of what that should look like now exist, but none has yet emerged as an obvious winner. Lists of what living things have in common do not add up to a theory of life. It's never clear why some items on the list are essential and others not. Coronaviruses have altered the course of history, and yet many scientists maintain they are not alive. Chemists are creating droplets that can swarm, sense their environment, and multiply - have they made life in the lab? Whether he is handling pythons in Alabama or searching for hibernating bats in the Adirondacks, Zimmer revels in astounding examples of life at its most bizarre. He tries his own hand at evolving life in a test tube with unnerving results. Charting the obsession with Dr Frankenstein's monster and how Coleridge came to believe the whole universe was alive, Zimmer leads us all the way into the labs and minds of researchers working on engineering life from the ground up.

The dangers of illegal drugs are well known and rarely disputed, but how harmful are alcohol and tobacco by comparison? What are we missing by banning medical research into magic mushrooms, LSD and cannabis? Can they be sources of valuable treatments? The second edition of Drugs without the hot air looks at the science to allow anyone to make rational decisions based on objective evidence, asking: *What is addiction? Is there an addictive personality? *What is the role of cannabis in treating epilepsy? *How harmful is vaping? *How can psychedelics treat depression? *Where is the opioid crisis taking us?
