home Extinction Risk and Diversification Are Linked in a Plant Biodiversity Hotspot Abstract It is widely recognized that we are entering an extinction event on a scale approaching the mass extinctions seen in the fossil record. Present-day rates of extinction are estimated to be several orders of magnitude greater than background rates and are projected to increase further if current trends continue. In vertebrates, species traits, such as body size, fecundity, and geographic range, are important predictors of vulnerability. Although plants are the basis for life on Earth, our knowledge of plant extinctions and vulnerabilities is lagging. Here, we disentangle the underlying drivers of extinction risk in plants, focusing on the Cape of South Africa, a global biodiversity hotspot. Author Summary The rapid loss of biodiversity is the most significant ecological challenge we face today. Citation: Davies TJ, Smith GF, Bellstedt DU, Boatwright JS, Bytebier B, Cowling RM, et al.

the free encyclopedia Bow Makers Unite Behind a Precious Tree As the earth’s forests and other natural resources face growing peril, humans are affected in many unexpected ways. In recent years, musicians have found themselves organizing to save the pernambuco, a medium-size tropical tree native to Brazil and known for its unique red wood. Discovered by French bow makers 250 years ago, it provides the primary — indeed only — wood for making high-end bows for professional musicians. (The tree is also known as the pau-brasil.) “No comparable substitute is known to bow makers or musicians,” the International Pernambuco Conservation Initiative, a charity created by bow makers around the world to finance replanting initiatives in Brazil, says at its Web site. But the tree, which grows primarily in Brazil’s Atlantic forest, has been so depleted by logging and agricultural and urban development that it is listed there as endangered. Profits from the book, available at a list price of $1,395, will go to the I.P.C.I.

Phrasal Verbs What is a Phrasal Verb? Phrasal verbs (also called multi-word verbs) are idiomatic expressions, combining verbs and prepositions to make new verbs whose meaning is often not obvious from the dictionary definitions of the individual words. They are widely used in both written and spoken English, and new ones are formed all the time as they are a flexible way of creating new terms. A phrasal verb consists of a verb and a preposition or adverb that modifies or changes the meaning; 'give up' is a phrasal verb that means 'stop doing' something, which is very different from 'give'. The word or words that modify a verb in this manner can also go under the name particle. Phrasal verbs can be divided into groups: Intransitive verbs These don't take an object Example: They had an argument, but they've made up now. Inseparable verbs The object must come after the particle. Example: They are looking after their grandchildren. Separable verbs In our phrasal verb list, we classify these as Separable [optional]
