Beef cattle production systems often rely on forage-based diets, consisting of pasture, as a low cost and widely accessible method for feeding herds. Whilst there are financial and practical benefits to forage-based diets, it is important to note that seasonal variations in pasture availability and nutritive quality can impact cattle performance and nutrition. So, are there any solutions to this?
We’re often told that the situation created by the attack of the new coronavirus is “unique” and “unprecedented.” And yet, at the same time, scientists assure us that the emergence of new viruses is “natural”—that viruses are always mutating or picking up and losing bits of DNA. But if lethal new viruses have emerged again and again during human history, why has dealing with this one been such a struggle?
With the world’s attention set on the COVID-19 pandemic, concerns have been growing over the lack of concentrated efforts in preventing the current spread of swine fevers. Both Classical Swine Fever and African Swine Fever cause high mortality in pigs but are the result of two unrelated viruses and, if safe and efficacious prevention methods are not present, can cause significant socioeconomic impacts in endemic countries.
On the afternoon of 27 April 1859, two top-hatted businessmen, standing in a gravel pit outside the French city of Amiens, were about to change history. Joseph Prestwich and John Evans had brought with them a photographer, scientific witnesses, and a great deal of zeal and perseverance to answer a longstanding question: how old was humanity?
[infographic] Cattle well-being and performance is negatively impacted by extreme heat stress. Introducing shade as a mechanism to mitigate this is one way to offer relief.
This year, LGBT+ History Month coincides with the 150th anniversary of Charles Darwin’s momentous sexological work The Descent of Man, and Selection in Relation to Sex, originally published on 24 February 1871. The occasion prompts reflection on Darwin’s highly equivocal handling of sex variations in the natural world, including intersexualities (“hermaphroditism”), transformations of sex, and non-reproductive sexual behaviours.
Was Darwin a one-trick pony? The scientists who most laud him typically cite just one of his ideas: natural selection. Do any know that his theory of evolution—like his take on psychology—was drawn from a comprehensive analysis of organisms as agents? This fact has long been eclipsed by the “gene’s-eye view” of adaptation which gained a strangle-hold over biology during the twentieth century—and hence over sociobiology and today’s “evolutionary” psychology.
A lake, sea, or coastal ocean turns into a dead zone when the supply of oxygen from the atmosphere and photosynthesis is overwhelmed by the use of oxygen during organic material degradation.
Charles Darwin’s birthday on 12 February is widely celebrated in the scientific community and has come to be known as “Darwin day.” In recognition of Darwin’s 212th birthday this year we have put together a list of ten interesting facts about the father of evolution.
The past several decades have been hard on Apis mellifera, the Western honey bee. Originally native to Europe, Africa, and the Middle East, Western honey bees have spread worldwide thanks to the nutritional and medicinal value of their honey, pollen, beeswax, and other hive products.
As the only birds with a nocturnal, predatory lifestyle, owls occupy a unique niche in the avian realm. Hunting prey in the dark comes with a number of challenges, and owls have evolved several features that leave them well-suited to this task.
No one likes to be threatened, and yet we threaten and are threatened all the time. From animal self-defence to how we raise our children, from religious teaching to gun ownership, capital punishment and nuclear deterrence, threat is an ever-present tool employed to influence an often-unpredictable external environment. But does it always work? And what are the consequences when it doesn’t?
Demanding the Indian government take action to clean and save the nation’s Mother River, the Ganga, activist and former civil engineer Professor G.D. Agarwal died from heart failure in 2018, after fasting for 111 days. Agarwal’s hunger strike remains symbolic of the mounting desperation many of us feel faced with the fragility of rivers, lakes, […]
There are 286 international transboundary river basins that are shared by 151 countries. These basins are the source for water as well as livelihoods to 2.8 billion people. In many of these places the already vulnerable and marginalised are at great risk due to problems managing water. Sudden, sharp changes in these basins are not […]
Charles Darwin is most known for his journey to the Galapagos Islands, and for the work he published around the theory of evolution, The Origin of Species, as a result of that trip. And though his time in the Galapagos was vital to Darwin’s work, he also visited many other places, a small selection of […]
We will get by the current pandemic. There will be a vaccine eventually. There will be other pandemics. Hopefully, we will be better organized next time. Waiting in the wings are the emerging impacts of climate change, the next big challenge. There will be no vaccine to stem sea level rise.
