This book is a totally fresh approach to observing birds in southern Africa. It affords you the opportunity to gather previously inaccessible and indecipherable information in the form of tracks and signs left behind by our avifauna. The book explores the unique details of the spoor, or tracks, of many species of birds. This is done in multiple ways including by observing their droppings, examining their feeding behaviour as well as their general nesting structures.

It’s remarkable how tracks and signs in nature help you to enrich your knowledge of bird species, providing knowledge as straightforward as the shape of the individual nests of our various species of weaver, or the ability to recognise and understand the role of a drum-site in the life of a bearded woodpecker, or even being able to see the subtle signs of a cardinal woodpecker on the various acacia pods which host its larval food.

Louis Liebenberg has generously provided some sketches of spoor he has made for his own publications, making these clear schematics available to assist with identification. Skulls, feathers, beaks and egg shells are also occasionally encountered, and a few examples of these will be included, as they also tell a story of a bird which has passed by. This approach to southern Africa’s birdlife will add tremendously to how we experience our wonderful avifauna.

A virologist's insight into how viruses evolve and why global epidemics are inevitable.

In 1993 a previously healthy young man was drowning in the middle of a desert, in fluids produced by his own lungs. This was the beginning of the terrifying Sin Nombre hantavirus epidemic and the start of a scientific journey that would forever change our understanding of what it means to be human. After witnessing the Sin Nombre outbreak, Dr Frank Ryan began researching viral evolution and was astonished to discover that it's inextricable from the evolution of all life on Earth. From AIDS and Ebola to the common cold, Ryan explores the role of the virus within every ecosystem on the planet.

His gripping conclusions shed new light on the natural world, proving that what doesn't kill you really does make you (and your species) stronger.

A journey through the history and science of epidemics and pandemics – from measles to coronavirus.

For centuries mankind has waged war against the infections that, left untreated, would have the power to wipe out communities, or even entire populations. Yet for all our advanced scientific knowledge, only one human disease – smallpox – has ever been eradicated globally. In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes, and the panic that a rapidly spreading epidemic can ignite.

But while we chase the diseases we are already aware of, new ones are constantly emerging, like the coronavirus that spread across the world in 2020. At the same time, anti-microbial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more.

Meera Senthilingam presents a timely look at humanity’s ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.

Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.

Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

Hierdie is 'n moet-lees boek vir:

• Lidmate wat ons Kerk graag wil help om 'n gesonde, geestelike tuiste vir Suid-Afrikaners van die 21ste eeu te bied.
• Die klakkelose napraters van die dogma wat dink ons Kerk is steeds op die regte pad.
• Die plastiekpredikante van die radio en televisie wat met eentonige reëlmaat soetsappige, sogenaamd godsdienstige, pleisters plak.
• Diegene wat reeds ons Kerk tot die ashoop van die geloof verdoem het.

In this book, Adrian Koopman describes the complex relationship between birds, the Zulu language and Zulu culture. A number of chapters look at the underlying meaning of bird names, and here we will find that the Zulu name of the Goliath Heron means ‘what gives birth to baby crocodiles’, the dikkop (umbangaqhwa) means ‘what causes frost’, and the African Hoopoe is a party-goer who wears a colourful blanket.

The book goes further than just Zulu names, exploring the underlying meanings of bird names from other South African languages and languages from Central and East Africa. Here we find birds with names that translate as ‘cool-porridge’, ‘kiss-banana-flower’ and ‘waiter-at-the-end-of-the furrow’.

A focus on Zulu traditional oral literature details the roles birds have played in Zulu praise poetry (including the praise poems of certain birds themselves) and in proverbs, riddles and children’s games. Also considered is traditional bird lore, examining the role played by various species as omens and portents, as indicators of bad luck and evil, as forecasters of rain and storm, and as harbingers of the seasons. Here we see that the Bateleur Eagle (ingqungqulu) is linked to war, the Southern Ground Hornbill (insingizi) to thunder and heavy rain, the Red-chested Cuckoo (uphezukokhono) to the start of the ploughing season, and the Jacobin Cuckoo (inkanku) to the start of summer.

Zulu Bird Names and Bird Lore discusses the Zulu Bird Name Project, a series of Zulu bird name workshops held between 2013 and 2017 with Zulu-speaking bird guides designed to confirm (or otherwise) all previously recorded Zulu names for birds, while at the same time devising new names for those without previously recorded names. The result has been a list of species-specific names for all birds in the Zulu-speaking region. Finally, the book turns to the role such new bird names can play in conservation education and in avi-tourism.

Your gut is astonishingly clever. It contains millions of neurons - as many as you would find in the brain of a cat - and is home to the microbiome, trillions of microbes that influence your mood, your immune system, and even your appetite.

In this groundbreaking book, Dr. Mosley takes us on a revelatory journey through the gut, showing how junk food and overuse of antibiotics have wiped out many good gut bacteria, leading to a modern plague of allergies, food intolerances, and obesity.

Drawing from the latest cutting-edge research, Dr. Mosley provides scientifically proven ways to control your cravings, boost your mood, and lose weight by encouraging a more diverse microbiome and increasing the good bacteria that keep you healthy.

Packed with delicious, healing recipes, meal plans, checklists, and tips, The Clever Guts Diet includes all the tools you need to transform your gut and your health, for life.

In this scientifically informed account of the changes occurring in the world over the last century, award-winning broadcaster and natural historian Sir David Attenborough shares a lifetime of wisdom and a hopeful vision for the future.

See the world. Then make it better.

I am 93. I've had an extraordinary life. It's only now that I appreciate how extraordinary.

As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day -- the loss of our planet's wild places, its biodiversity. I have been witness to this decline. A Life on Our Planet is my witness statement, and my vision for the future. It is the story of how we came to make this, our greatest mistake -- and how, if we act now, we can yet put it right.

We have one final chance to create the perfect home for ourselves and restore the wonderful world we inherited. All we need is the will do so.

Everything you need to know about race (but were afraid to ask), previously published in 2015 as Black Brain, White Brain: Is Intelligence Skin Deep?.

In academic journals and on internet message boards, certain scientists and thinkers are laying siege to one of the great taboos. Could it be, they ask, that racism has a rational basis in science? These ideas are no longer limited to the fringe: race-based studies of intelligence have been discussed by thinkers such as Steven Pinker, Sam Harris and Jordan Peterson. If true, it would provide an intellectual foundation for so many of the attitudes that characterise the right wing, justifying inequality and discrimination. Gavin Evans tackles the nature vs nurture debate head-on, examining the latest studies on how intelligence develops and laying out new discoveries in genetics, palaeontology, archaeology and anthropology to unearth the truth about our shared past.

In doing so, Skin Deep demolishes the pernicious myth that our race is our destiny, and instead reveals what really makes us who we are.

The humble and industrious dung beetle is a marvellous beast: the 6 000 species identified so far are intricately entwined with human history and scientific endeavour.

These night-soil collectors of the planet have been worshipped as gods, worn as jewellery, and painted by artists. More practically, they saved Hawaii from ecological blight, and rescued Australia from plagues of flies. They fertilise soil, cleanse pastures, steer by the stars, and have a unique relationship with the African elephant (along with many other ungulates). Above all, they are the ideal subject for biological study in an evolving world.

In this sweeping history of more than 3 000 years, beginning with Ancient Egypt, scientist Marcus Byrne and writer, Helen Lunn capture the diversity of dung beetles and their unique behaviour patterns. Dung beetles’ fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy.

With over 6 000 species found throughout the world, these unassuming but remarkable creatures are fundamental to some of humanity’s most cherished beliefs and have been ever present in religion, art, literature, science and the environment. They are at the centre of current gene research, play an important role in keeping our planet healthy, and some nocturnal dung beetles have been found to navigate by the starry skies. Outlining the development of science from the point of view of the humble dung beetle is what makes this charming story of immense interest to general readers and entomologists alike. This entertaining outline of the development of science from the the beetle’s perspective will enchant general readers and entomologists alike.

WHEN we eat may be as important as WHAT we eat.

Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.

Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

Elephants are as unique as people. They can be clever and curious or headstrong and impulsive, shy or sociable. Learn to know them as individuals as well as a species in this evocative account of years spent studying elephant behaviour in the wild.

Watching a family out for a swim on a hot day, Dr Hannah Mumby notes grandmothers, mothers, sisters and children exchanging noisy greetings, a consistent stream of close-range vocalisations, intermittent touching, co-operative herding of babies and frequent stopping for snacks. A close and interconnected family. But in this family, the adults weigh several tons each and the babies wave trunks playfully at one another. This is a herd of elephants.

That elephants are intelligent, sentient beings is common knowledge, but so much about their day-to-day lives and abilities remains unknown. How do they communicate with one another over seemingly impossible distances? How do males spend their lives once they have left their mothers’ herds? And how much do they really remember?

In this lyrically written and deeply personal account of several years of field research, Mumby reverently describes her own elephant encounters, alongside an exploration of the most up-to-date discoveries about the lives of these gentle giants. Learn how elephants live, travel, mate, raise children and relate to one another, and reflect on how they think and feel. Understanding elephants as individuals closes the gap between human and animal and has powerful applications in the critical field of elephant conservation.

"Fascinating and exhilarating-Sean B. Carroll at his very best."-Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the world Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world. Like every other species, we humans are here by accident. But it is shocking just how many things-any of which might never have occurred-had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death. This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.
