Great truths are often so pervasive or in such plain view as to be invisible. This is the case with bees and their food plants, the world’s quarter million flowering plant species, especially because it’s easy to overlook small things in a world in which whales and elephants hold the imagination of the public. Little […]
Sometimes spouses will look back on the time of their getting to know one another and say, half-jokingly, that on a given occasion one was putting the other to the test.
Established in 1903, Journal of Heredity covers organismal genetics across a wide range of disciplines and taxa. Articles include such rapidly advancing fields as conservation genetics of endangered species, population structure and phylogeography, molecular evolution and speciation, molecular genetics of disease resistance in plants and animals, genetic biodiversity and relevant computer programs.
Tool use, once considered unique to our species, is now known to be widespread in the animal kingdom. It has been reported in most of the major taxonomic groups, with notable exceptions being myriapods, amphibians and reptiles. In insects, one of the best documented examples of tool use is seen in members of the ant […]
Honey bee colonies have historically been considered as marvels of evolution resulting in perfectly cooperative and harmonious societies, and exemplars of what we humans might achieve. This is an appealing image to many, but it is of course a caricature. Nobody is perfect, not even honey bees.
“Rivers are the gutters down which flow the ruins of continents.” – Luna B. Leopold Luna Leopold understood that rivers are far more than gutters. In a 1964 textbook, he wrote figuratively of the role of river channels in transporting sediment to lower elevations. In other writings, however, Leopold’s understanding of rivers was closer to […]
True aficionados of the earthly apocalypse cannot fail to have noted the deepening pessimism in discourses on what is often euphemistically referred to as “climate change”, but what should be designated “environmental catastrophe”. The Paris Agreement of 2015 conceded the need to limit global warming to 1.5 degrees Celsius, albeit without binding nations to either achieve this specific target or impose specific binding targets in turn on the worst offenders, namely the fossil fuel industries.
In the agricultural industry, recombinant DNA technology allows for DNA to be transferred from one organism to another, creating Genetically Modified Organisms (GMOs). Four crops constitute the vast majority of the GM crop production: maize, canola, soybean, and cotton. Since 1995, GM crops have been grown commercially and the global area sown to these crops has expanded over 100-fold over the past two decades.
Microorganisms are known for their ability to adapt to any environment. We can find them in the most hazardous places on Earth. Their invisible work has led to visible results ― terraforming the planet billions of years ago and converting it into the viable green world that is today. Their ability to utilize and adapt to any available substrate in order to gain energy kept the balance in the ecosystem until humans become dominant species.
“Environmental law ensures that collective action in relation to environmental problems is authoritative and consistent with the rule of law and other principles of legitimate action.” – Elizabeth Fisher, Environmental Law: A Very Short Introduction
In 1969, half a century ago, astronauts first landed on Earth’s sole moon. The first successful robotic landers touched down on the much more distant Venus and Mars in 1970 and 1976, respectively, and in the same decade spacecraft flybys provided the first, fleeting close-ups of Jupiter and Saturn. It was not until two decades […]
Earlier this month, we explored the world of rabbits and facts to enhance our knowledge of the ubiquitous mammal. Now on international rabbit day, we are focusing on the eastern cottontail rabbit, the most common species in North America. What makes it different from other rabbit species? What commonalities can be found across species?
With over 10 million active researchers, more than 2 million scientific articles published each year, and an uncontrolled spread of bibliometric indicators, contemporary science is undergoing a profound change that is modifying consolidated procedures, ethical principles that were deemed inalienable and traditional mechanisms for the validation of scientific outputs that have worked successfully for the last century.
Popular as pets, considered lucky by some, and widely recognised as agricultural nuisances, rabbits are commonplace all over the world. Their cute, fluffy exterior hides the more ingenious characteristics of this burrowing herbivore, including specially-adapted hind legs, extra incisors, and prolific breeding capabilities. Whilst rabbits thrive in most areas, certain species face the common struggle of their specialist habitats being destroyed, and myxomatosis has devastated rabbit populations in the past, at one point destroying 99% of the rabbit population of the United Kingdom.
Most practicing scientists scarcely harbor any doubts that science makes progress. For, what they see is that despite the many false alleys into which science has strayed across the centuries, despite the waxing and waning of theories and beliefs, the history of science, at least since the ‘early modern period’ (the 16th and 17th centuries) is one of steady accumulation of scientific knowledge. For most scientists this growth of knowledge is progress. Indeed, to deny either the possibility or actuality of progress in science is to deny its raison d’être.
Pride is one of the most widely-recognised animal collectives in the world. We often picture lions among their family unit, whether they be standing proudly together or hunting down a doomed antelope. These famous social groups are usually formed of between three and ten adult females, two or three males, and the pride’s latest litters of cubs, and they live together (most of the time) across Africa and in the Gir Forest Sanctuary.
