Nature S Flyers

'Nature's Flyers' is a detailed account of the current scientific understanding of the primary aspects of flight in nature. The author explains the physical basis of flight, drawing upon bats, birds, insects, pterosaurs and even winged seeds.

Examining the development of ecofeminism from the 1980s antimilitarist movement to an internationalist ecofeminism in the 1990s, Sturgeon explores the ecofeminist notions of gender, race, and nature. She moves from detailed historical investigations of important manifestations of US ecofeminism to a broad analysis of international environmental politics.

Story of Ms. Jenkins' cats in her Queens neighborhood.

W.D.Hamilton (1936-2000) was responsible for a revolution in thinking about evolutionary biology - a revolution that changed our understanding of life itself. He played a central role in the realization that what matters in evolution is not the survival of the individual but of the survival of its genes. This provided the solution to the long standing problem of animal altruism that vexed even Darwin himself, and in due course resulted in terms like selfish genes, kin selection, and sociobiology becoming familiar to a wider public. Hamilton went on to solve many more major problems, and open up ever new fields - he shaped much of our currentunderstanding of central problems including the evolution of sexual reproduction and ageing. He became world famous and garnered international prizes.But this is all in hindsight. In fact, Hamiltons recognition came late - his career is a classic case of misunderstood genius. In this illuminating and moving biography Ullica Segerstrale documents Hamiltons extraordinary life and work, revealing a man of immense intellectual curiosity, an uncompromising truth-seeker, a naturalist and jungle explorer, a risk-taker, an unconventional scientist with a poets soul and a deep concern for life on earth and mankinds future.

More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.

This box set contains all five of the Sinful Natures Series of standalone but connected forbidden gay romance novels and includes three exclusive epilogues. Unholy Craving He resurrects the sinful nature I’ve rejected in my strive for purity. Isaac’s hunger for sin rivals mine, the kind that consumes. Burns like fire and brimstone. But I can’t allow him to be the second one to pay the price for my sins. Unholy Yearning He distracts me from the path God has set me upon. Levi’s yearnings mirror mine, the kind that dominates my will. Incinerates and leaves me powerless to my sinful nature. But I can’t allow it—a fall from grace would ruin us both. Unholy Desire His presence fills the emptiness in my life, but my sinful nature longs for more. Every inch of him—in my heart, in my body, making me feel whole again. Unholy Temptation Giving into my sinful nature, touching the forbidden, won’t just tear apart the life I’ve built for myself. It will ruin my family as well. Unholy Addiction He comes in like a rainstorm, washing away the dust from a too-long drought. But giving into my new addiction will land me at rock bottom—a place I know I won’t escape again. *No cliffhangers and guaranteed HEAs between each couple.

In step with the surge of interest in the endoplasmic reticulum, the current volume takes an integrated look at this functionally diverse organelle. Coverage includes protein translocation and export, lipid metabolism, antigen presentation, and many other subjects, gleaned from such diverse fields as cell biology, enzymology and membrane biochemistry, immunology, and signal transduction.
