"s are the most biologically diverse and ecologically complex of terrestrial ecosystems, and are disappearing at alarming rates. It has long been suggested that rapid forest loss and degradation in the , if unabated, could ultimately precipitate a wave of species extinctions, perhaps comparable to mass extinction events in the geological history of the Earth. However, a vigorous debate has erupted following a study by Wright and Muller-Landau that challenges the notion of large-scale tropical extinctions, at least over the next century."

"In the , alters forest–climate interactions in diverse ways. On a local scale (less than 1 ), elevated desiccation and wind disturbance near fragment margins lead to sharply increased tree mortality, thus altering dynamics, composition, dynamics and . Fragmented forests are also highly vulnerable to edge–related fires, especially in regions with periodic droughts or strong dry seasons. At landscape to regional scales (10–1000 km), habitat fragmentation may have complex effects on forest–climate interactions, with important consequences for atmospheric circulation, water cycling and precipitation. Positive feedbacks among , regional climate change and fire could pose a serious threat for some tropical forests, but the details of such interactions are poorly understood."

"Humankind has dramatically transformed much of the Earth’s surface and its natural ecosystems. This process is not new—it has been ongoing for millennia—but it has accelerated sharply over the last two centuries, and especially in the last several decades. Today, the loss and degradation of natural history can be likened to a war of attrition. Many natural ecosystems are being progressively razed, bulldozed, and felled by axes or chainsaws, until only small scraps of their original extent survive. Forests have been hit especially hard: the global area of forests have been reduced by roughly half over the past three centuries. Twenty-five nations have lost virtually all of their forest cover, and another 29 more than nine-tenths of their forest ( 2005)."

"Passing by the mountain village of —a quaint, artsy town known for its Saturday tourist markets—the changed abruptly to open . Stately rainforest trees were replaced by s, s and s, with a ground layer of punctuated by large, oddly shaped . s and s, their flowers shaped like bottle-brushes, grew in dense clumps along a few meandering creeks."

"Each year—as a result of , automobiles, , , and tropical —humankind spews some 8 billion tons of , , and other carbon-based pollutants into the atmosphere. The net effect, as we all know, has been an alarming rise in air pollutants—particularly carbon dioxide, which has increased by more than a third, from 280 to 380 parts per million (ppm), since the onset of the industrial era. Equally distressing is that these emissions are accelerating, because countries like the United States have failed to rein their burgeoning emissions and because rapidly developing countries like China, India, and Brazil are increasingly adopting the energy-consumptive lifestyles of industrial nations. From 1800 to 1960, for example, the average annual increase in atmospheric carbon dioxide concentrations was just 0.2 ppm, but this jumped to 1.4 ppm from 1960 to 2000 and has since risen to 2.3 ppm."

"Harrison is no nostalgic reactionary. He acknowledges modernity’s gifts. But he warns against monochrome narratives of progress. One of his most provocative claims is that science, too, relies on “ implicita.” …As a scholar of new religious movements, I find Harrison’s thesis electrifying. He doesn’t mention my field, but I’ll extend his argument: many new religions are a renaissance of “fides implicita.” Converts don’t join because they’ve dissected theological treatises (although some may read them later). They join because they trust a guru, a prophet, a community. Just like early Christians and Muslims. The intellectual scaffolding may come later—or not at all. So, is “fides implicita” obsolete? Has secular science vanquished religion? Harrison—and I—say: not so fast. Belief, in its ancient form as trust, is alive and well. It’s just wearing new clothes."

"As we discover , we suffer from a variety of s, both in our nearby and distant searches. The most significant effect is – a selection effect which leads brightness limited searches finding brighter than average objects near their sensitivity limit. This bias is caused by the larger volume in which bright objects can be uncovered compared to their fainter counterparts. Malmquist bias errors are proportional to the square of the intrinsic dispersion of the distance method, and because SN Ia are such accurate distance indicators, these errors are quite small – approximately 2%. We use s to estimate these effects, and remove their effects from our s."

"… one does not expect a . To my mind, I was genuinely surprised because when you make a discovery of acceleration–well, what causes the acceleration? Well, we give it a name–'–but we don’t understand it yet. I would not be surprised if we don’t understand it during my lifetime. Without understanding it, I felt it wouldn’t be worthy of a Nobel Prize. The fact that it was given pretty timely–you know, I was only 44 last year–was a bit of surprise."

"With the as an anchor, theory converged on a standard model of the universe, which was still in place in 1998, at the time of our discovery of the . This standard model was based on the theory of general relativity, and two assumptions. assumption one was that the , and assumption two that it is composed of normal , i.e. matter whose density falls directly in proportion to the volume of space, which it occupies. Within this framework, it was possible to devise observational tests of the overall theory, as well as provide values for the fundamental constants within this model – the current expansion rate (), and the average density of matter in the universe. For this model, it was also possible to directly relate the density of the universe to the rate of cosmic deceleration and the geometry of space. it stated that the more material the faster the deceleration, that above a critical density the universe has a and below this a ."

"The last works of a great artist have always a peculiar interest, and when they are the works of his old age they often show a peculiar change. The greatest artists do not copy themselves: stereotyping is fatal to creation. For creation, it cannot be denied though frequently forgotten, is always the production of something new, and this is why so often it is neglected or scorned by contemporaries. The creative artists, though their work corresponds with experience, are always outstripping experience, stretching forward to something they have never fully known, entering fresh worlds only half realised. Beethoven, Rembrandt, Titian, Sophocles, Shakespeare, Milton, Goethe, all show this in various ways. There is something unearthly in their closing work, and at the same time they are more at peace with this earth than ever. Nor is this because the world appears less terrible to them than it did, but because they seem to discern something more which countervails the terror."

"... At the outset we are shown the two great armies, Greek and Trojan,—both winning our sympathy,—the one fighting for honour and justice, the other for home and country. We are shown , the fair woman who is at once the cause of the war and its prize; we are shown the two kings, in his noble endurance, in his restless activity; we are shown the two champions, and , both lovable and attractive to us, sworn enemies to one another."

"A quarter of a century ago, when the were first discovered, all scholars were struck by their likeness to the works of later Greece. Even now, when the knowledge of dissimilarities in detail has obscured for many minds this broad resemblance, no one would assert that a or is impossible."

"When the idea of Democracy first took hold of the modern world, it brought with it to many minds the demand for the . To many minds, but not to all, and this because the strongest arguments for that independence are bound up with the fundamental conceptions of the democratic ideal, and not with the secondary advantages of a democratic state, and there are always minds on whom the second have far more influence than the first. It is probably for a similar reason that the has made so little headway in Europe during the last century. For this has been a time of detailed work in legislation, rather than of far-reaching ideas."

"Like several other interwar liberal internationalists, F. Melian Stawell was a classicist by training, set for an illustrious career at working simultaneously on the ancient Greeks and contemporary world order. Stawell is best known as the author of The Growth of International Thought, a book increasingly cited, if not read, as the first to use the term ‘international thought.’"

"... After Philo and Plato, it was little use to say that Christ was merely like God, and the Spirit that came to us like both. Only the thorough-going assertion of unity could satisfy the longings and quiet the doubts that had been raised."

"Melian Stawell (1869-1936) begins life as a certain kind of outsider. Born into an elite Australian colonial family, she received great early encouragement in her education, had access to a home library, and studied at and then Cambridge. Henceforth her academic, political, and friendship base was in England, wher she wrote a great number of significant texts in classics, as well as Aristotle, the League of Nations, Women and Democracy, and in particular a work on the (1911) that is still highly regarded. Her work is in the Library of Leonard and Virginia Woolf at -, including The Growth of Intellectual Thought (1929), with reading annotations by ."

"The first of the 'complete theories' of evolution developed in modern times was the of (1969; translation of work published in 1922). While badly hampered by an ignorance of genetics, slow to reach the Russia of the early twentieth century, Berg's consideration of the Darwinian model led him to the conclusion that it was incompatible, at least as the major mechanism, with what he knew of the pattern of living organisms and their evolution."

"There has been a lot of discussion about ‘the species question’ over the past 20–30 years, and several surveys have converged on the essence of what we mean by species: they are evolutionary lineages ... Species thus have a real existence. This settles the ontological status of the species concept, but it does not necessarily solve the question of how to recognise them; the most logical way of defining species operationally is by the so-called Phylogenetic Species Concept: ‘A species is the smallest population or aggregation of populations which has fixed heritable differences from other such populations or aggregations’ ..."

"Taxonomy has a well-defined role, which is much more than simply stamp-collecting and pigeon-holing. are the units of classification, and ; as such they must be defined as objectively as possible. The biological species concept, still widely used in biology, though predominantly by non-taxonomists and all too often misunderstood, is a process-based concept, which offers no criterion for the classification of beyond and hypothesis. The phylogenetic species concept—a pattern-based concept—is as nearly objective as we are likely to get. Amount of difference is not a criterion for recognizing species. It is not possible to insist on at the specific level, but it is mandatory for the higher categories (, , etc.). The rank we assign to a given supraspecific category should be determined by its time depth."

"This article reviews changes in , especially those pertaining to the meaning of the term species, since its inception two and a half centuries ago. Despite continuing discoveries and the involvement of competent practitioners, the adoption of the polytypic species concept, especially underpinned by the biological species concept, ensured that primate taxonomy was in a sorry state by the middle of the twentieth century. In the latter half of the twentieth century, a gradual rethinking of the nature of species took place, and many different species concepts were proposed. The phylogenetic species concept has been widely adopted over the past ∼20 years, sustained by a gradual realization that species are evolutionary lineages. This review provides examples of how the old way of thinking about species hampered our understanding of primate biodiversity and of how the phylogenetic species concept (or the diagnosability criterion under the general lineage concept) has clarified matters, opening them up for discussion. The adoption of this evolutionary view of species has implications for conservation, particularly because it increases recognition of biodiversity."

"While studying under the supervision of , he had the good fortune to meet , , and , all of them famous researchers in the field of Anthropology and Primatology. Equally important to Colin, as he recalled in Groves (2008), was his meeting with − then at ."

"This useful book surveys endangered species (and subspecies), stating where each lives and why it is endangered. ... The non-Australian conservationist will find much of interest here. The devastation wreaked by introduced species has been astounding: so many formerly widespread species have been swept off their entire mainland ranges by competition from the introductions, survivng only if their ranges happened to include offshore islands which were not reached by rabbits, hares, foxes, feral cats, introduced rats and mice, goats, donkeys, horses, camels, buffaloes, sparrows, starlings, blackbirds."

"The place of origin of the is unknown, but both and ', today neatly separated by the Sahara, found their earliest ancestors in the , while a Potamochoerine, ', survived in into the ."

"As new methods of investigation become available to us, levels of analysis can be conducted: nuances undreamed of by , , , even . Science had advanced, but human behavior has not. People still hunt gorillas for food or trophies, and still cut down their forests; but now those same advances in science also enable forests to be cut down more efficiently, gorillas to be hunted more efficiently, human populations to increase ever faster and press in on the remaining habitat, so that our second-closest relative is threatened with disappearing for ever. More and more, the work of taxonomists and other biologists must be put into the service of conservation."

"The United States has the of the richest nations. It has the by far. It has among the highest child mortality rates. It has the highest . It has one of the lowest levels of voter registration in the rich countries. In essence, it scores extremely poorly on almost all of the comparative measures when compared with other developed states. I visited China on one of these missions about a year ago and what I found was a country that has , but in terms of extreme poverty, has made an absolutely concerted and genuine attempt to eliminate poverty and has succeeded to an important extent. By 2020, they will in fact have no one living in extreme poverty, unlike the United States. While I don’t for a minute want to suggest that the political system [in China] is desirable or even compatible with democratic standards, I would very much welcome an American government that shows a determination to lift everyone out of extreme poverty. I think that’s what politics should be all about, and it’s not happening in the United States."

"In short, the use of metaphor involves both the awareness of duality of sense and the pretense that the two different senses are one."

"It is a confusion to present the items of one sort in the idioms of another -- without awareness. For to do this is not just to cross two different sorts; it is to confuse them. It is to mistake, for example, the theory for the fact, the procedure for the process, the myth for history, the model for the thing and the metaphor for the face of literal truth."

"However appropriate in one sense a good metaphor may be, in another sense there is something inappropriate about it. This inappropriateness results from the use of a sign in a sense different from the usual..."

"The mechanical philosophy is a case of being victimized by metaphor. I choose Descartes and Newton as excellent examples of metaphysicians of mechanism malgré eux, that is to say, as unconscious victims of the metaphor of the great machine. Together they have founded a church, more powerful than that founded by Peter and Paul, whose dogmas are now so entrenched that anyone who tries to reallocate the facts is guilty of more than heresy."

"Thus to the plain man there may be no metaphor in Aristotle's "substance", Descartes' "machine of nature," Newtonian "force" and "attraction," Thomas Young's "kinetic energy" and Michelangelo's figure of Leda. Placed in their customary contexts these present nothing to him but the face of literal truth. To the initiated, however, who are aware of the "gross original" senses as well as the now literal senses , they may become metaphors. There are no metaphors per se...."

"Knowing the theory of anything is contrasted with know-how in all the arts...Beethoven..Michelangelo..Shakespeare, all great exponents of know-how, probably knew how to manipulate their instruments to achieve the desired results long before they knew the theory of their art. Perhaps some of them never bothered to learn the theory. On the other hand, there are many who know the theory better than these, but who lack know-how....Although we acquire the skill of understanding words by experience, so that we know the correlations between them and things, between words and other words, and between words and feelings and actions, we do not do it by inductive reasoning. Nor must we think that we do it by deductive reasoning... In the main, words are cues rather than clues."

"The metaphysics that still dominates science and enthralls the minds of men is nothing but a metaphor, and a limited one."

"(Berkeley) gave the impression that he too was a victim, that he took the assertion "Mind is a substance" in a literal sense, that he thought that the soul was actually a "substance" "in" which ideas "inhere" and which "supports" the ideas, ect. hence the expression "in the mind".... Berkeley had a purely substantivalist conception of the mind, confirmed by his private utterances."

"There is a remedy against the domination imposed, not by generals, statesmen, and men of action, whose power dissolves when they retire, but by the great sort-crossers, whose power increases when they die- the remedy of becoming aware of metaphor..."

"Climate change is a transenvironmental challenge that requires the integration of transgenerational, transpeciesist, and transnational practices and knowledge."

"As a species, humans have become the Earth’s number-one predator."

"Environmental degradation is calling us to the witness stand of history. It demands we testify against ourselves and mount a case in our defense. Ultimately, we are all agents of history. To reduce ourselves to a role of mere observation is to deny us of our humanity."

"A turbulent emptiness seized the people as they moved into a post-Christian, post-Enlightenment era. No one any longer knew the direction of the river of life. No one had anything to say."

"Australians must decide for themselves whether this was the land of the dreaming, the land of the Holy Spirit, the New , the Millennial , or the new demesne for to infest."

"Civilization did not begin in Australia until the last quarter of the eighteenth century. The reason lies partly in the environment and way of life of the people inhabiting the continent before the coming of the European, and partly in the internal history of those Hindu, Chinese, and Muslim civilizations which colonized and traded in the archipelago of south-east Asia. The early inhabitants of the continent created cultures but not civilizations."

"By the middle of the seventeenth century the Dutch had written the very first page in the history of European civilization in Australia by stating that there was no good to be done there. William Dampier popularized this idea amongst the English reading public half a century later."

"The proposals for the use of a southern continent had a history almost as long though by no means so distinguished as the history of its discovery. Some saw it as land dedicated to the Holy Spirit; some saw it as a land fit only for the refuse of society, on the principle that the political body, like the human body, is often troubled with vicious humours, which one must often evacuate."

"The inhospitable environment and the past had predisposed the minds of its European inhabitants to hand over the government of their country to men who were wary of visionaries and all those who held out a promise of better things for mankind. Australians seemed chained for decades to come to the role of being a New Britannia in another world. The young Henry Lawson and all the other prophets of Utopia were doomed to a bitter disenchantment."

"Tigris! Torrent of four thousand years, Millions, men of war sucking at your strength, Living in holes at your side, Agape as you broke bridges, sent ferrymen adrift! How many armies sought to cross you here, How muezzins lived and died, call’d to prayer; Yet you seemed aloof to all their striving, Your ripples looked indifferent to their stares, Their drinking, marching, gravities."

"I have come to believe, that in our relationship with creation we are called to evoke and affirm our interconnectedness with the rest of the world. This is what I would call the ecumenical imperative of care for creation. This perception of interconnectedness reminds us that the earth unites us all, before and beyond any doctrinal, political, racial or other differences."

"Not only the greater part of the religious vocabulary, but also most of the cultural vocabulary of the Quran is of non-Arabic origin."

"Climate change is already impacting every inhabited part of our planet."

"My research focuses on how the Earth’s climate has behaved over the last millennium, and what that tells us about the climate changes we are seeing now."

"I spend every day looking at the data that tells us each of those climate extremes will keep getting worse."

"The past climate records that I develop come from corals, caves and ice cores, and I combine these with climate model data to study climate changes."
