The global market for herbs and spices is complex with diverse supply chains and products being sourced from a variety of businesses ranging from large scale producers to smallholders. Many herbs and spices grow wild and are farmed on a village or subsistence scale and there are often many intermediaries in the supply chain from farmer, collector to middle-man before arrival at the origin proce…
Biomolecules contain mainly carbon, which behaves as it always does in organic compounds, forming 4 bonds, usually with a tetrahedral arrangement. (PP 2) The carbon skeleton can be linear, branched, cyclic, or aromatic. Other important elements are H, O, N, P and S. About 30 elements are required by biological systems, including iodine and many metals, though most of these are needed in only tr…

Heat radiation at the nanoscale is a relatively young but flourishing research field, that has attracted much attention in the last decade. This is on the one hand due to the fact that this effect is nowadays experimentally accessible (Hu et al. (2008); Kittel et al (2005);Narayanaswamy et al. (2008); Ottens et al. (2011); Rousseau et al. (2009); Shen et al. (2009)), and on the other hand due t…
Radiation is energy that moves through space or matter at a very high speed. This energy can be in the form of particles, such as alpha or beta particles, which are emitted from radioactive materials, or waves such as light, heat, radiowaves, microwaves, x-rays and gamma rays. Radioactive materials, also known as radionuclides or radioisotopes, are atoms that are unstable. In nature, there is a…
Radioactivity is a spontaneous process characteristic of atoms with unstable nuclei in which the nucleus releases energy either as a particle with kinetic energy or as electromagnetic energy. Upon release of this energy the nucleus may be stable or it may still be unstable and will acquire stability through an additional transformation(s). The original species prior to radioactive disintegrati…
Although in many respects chameleon behavior resembles that of other lizards, there are also unusual characteristics associated with their unique morphology (Chapter 2). Chameleons are perhaps most famous for their ability to change color, a characteristic that has seen the term chameleon adopted in popular language to mean someone changeable or who unconsciously mimics others. Color and color …

We value birds in many ways: culturally, artistically, philosophically and economically. Throughout history, many of our most enduring cultural symbols have been birds, from Horus the Egyptian god of creation, often depicted as a falcon, to Quetzalcoatl, based on the Resplendent Quetzal Pharomachrus mocinno, who dominated the traditions and beliefs of the Maya and Aztec Indians of Central Ameri…
The hot compact core of the Sun – where the energy is created – has a radius of about 175,000 km. Outside the core is a layer where the energy is transported by electromagnetic radiation or photons. This layer is called the radiation zone. Further out we find the convection zone where the energy is transported as a turbulent churning motion similar to a pot of boiling soup. The visible surf…
Globally, leopard is the most widely distributed and persecuted cat amongst large cat species like the tiger across much of its distribution range and with lion and clouded leopard in certain areas of its distribution range. Owing to its very high adaptability for surviving in varieties of habitats and opportunitistic feeding behavior, it is often found to be at the center of the human wildlife…
These days few biologists would try to pin their religious faith, if they have any, on biological evidence, and the apparent design to which Paley referred would be attributed instead to the evolutionary mechanism which Charles Darwin called natural selection. Darwin’s theory of evolution by natural selection is universally accepted among serious biologists (except for a …

Today, polar bears roam the northern reaches of the planet, but as their sea-ice habitat continues to shrink due to Arctic warming, their future in the U.S. and ultimately their continuation as a species are at risk. Their eventual reprieve turns on our collective willingness to address the factors contributing to climate change and, in the interim, on our ability to improve the chances that po…
African Penguins breed on only 25 islands and at 3 mainland sites between Algoa Bay in South Africa and central Namibia and nowhere else in the World. It is the only penguin that breeds in Africa. There are another 17 species of penguins. The first nest at Stony Point was found in 1982. During the 20th century the global population of this penguin decreased by almost 90% and it is now considere…

The science is clear: halting loss of tropical2 forests—the home and heritage of Indigenous Peoples (IPs) and local communities (LCs)3 who have long been their guardians—is necessary to address climate change and achieve the Paris Agreement goals.i Yet, tropical forest loss and degradation have proven difficult to reduce, generating large greenhouse gas (GHG) emissions and threatening IPsâ…
The global warming consequences – from greenhouse gas emissions and a reduction in the capacity of forests to absorb and store carbon – are grave, and likely to be especially acute in tropical regions themselves. Forest loss also leads to the breakdown of critical ecosystem services, such as water provision, and interferes with regional climatic patterns, with serious knockon effects for a…
Climate change is already impacting tropical forests around the world, including through distributional shifts of forest biomes, changes in species composition, biomass, pests and diseases, and increases in forest fires (high confidence). These impacts are often compounded by non-climatic factors such as conversion of land for other uses, burning to clear land, mining, and road and infrastructu…

One of the most critical uses of foliar characters is in interpreting the angiosperm fossil record. Although fossil reproductive structures comprise an important source of data (e.g., Friis and Skarby, 1982; Basinger and Dilcher, 1984; Herendeen et al., 1999; Crepet et al., 2004; Friis et al., 2006), compressions and impressions of leaves are the most common macroscopic angiosperm fossils. Beca…
lthough an organized antivivisection movement did not begin to flourish until the second half of the nineteenth century, the increasing use of animal experimentation in the emerging science of physiolog y in the first half of the century led to heightened con-cerns about the practice, especially in Britain. The work of the French scientist Francois Magendie, one of the pioneers of the new scien…
If you move at high speed, time slows down, space squashes up and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequenc…
