Some new taxa of Astragalus L. (Leguminosae) from China and Nepal

L. R. Xu Prof. Dr.
During the work on the genus Astragalus for the Flora of China, some more new species could be found among the unnamed material from the herbaria of Beijing and Kunming. Furthermore a new section had to be described. They are described here: Sect. Poliothrix:A. blandulus, A. hysophilus, A. jumlaensis, A. montivagus, A. oreocharis, A. praeteritus, A. yutaniensis; Sect. Pseudosesbanella sect. nova: A. notabilis.

The cycle of instability: stress release and fissure flow as controls on gully head retreat

A. J. C. Collison
Abstract Gully head and wall retreat has commonly been attributed to fluvial scour and head collapse as a result of soil saturation, sapping or piping. The empirical evidence to substantiate these conceptual models is sparse, however, and often contradictory. This paper explores the hydrological and mechanical controls on gully head and wall stability by modelling the hydrology, stability and elastic deformation of a marl gully complex in Granada Province, south-east Spain. The hydrological and slope-stability simulations show that saturated conditions can be reached only where preferential fissure flow channels water from tension cracks into the base of the gully head, and that vertical or subvertical heads will be stable unless saturation is achieved. Owing to the high unsaturated strengths of marl measured in this research, failure in unsaturated conditions is possible only where the gully head wall is significantly undercut. Head retreat thus requires the formation of either a tension crack or an undercut hollow. Finite-element stress analysis of eroding slopes reveals a build up of shear stress at the gully head base, and a second stress anomaly just upslope of the head wall. Although tension cracks on gully heads have often been attributed to slope unloading, this research provides strong evidence that the so called ,sapping hollow' commonly found in the gully headwall base is also a function of stress release. Although further research is needed, it seems possible that ,pop out' failures in river channels may be caused by the same process. The hydrological analysis shows that, once a tension crack has developed, throughflow velocity in the gully headwall will increase by an order of magnitude, promoting piping and enlargement of this weakened area. It is, therefore, possible to envisage a cycle of gully expansion in which erosion, channel incision or human action unloads the slope below a gully head, leading to stress patterns that account for the tension crack and a stress-release hollow. The tension crack promotes faster throughflow, encouraging hollow enlargement and piping, which undercut the gully head. The tension crack permits the development of positive pore-water pressures behind the gully head, leading either to failure or contributing to toppling. Finally the debris may be eroded by fluvial action, unloading a new section of slope and completing the cycle of gully head retreat. Copyright © 2001 John Wiley & Sons, Ltd. [source]

Historical biogeographical patterns of the species of Bursera (Burseraceae) and their taxonomic implications

David Espinosa
Abstract Aim, The plant genus Bursera, with 104 species of trees and shrubs, has been used as a model for biogeographical analyses because of its high species richness and large number of endemic species. The biogeographical patterns of Bursera and their implications for its phylogenetic classification are reviewed in order that some hypotheses on the historical biogeography of tropical Mexico can be proposed. Location,Bursera is found in the south-western USA, most of Mexico, mainly below 1700 m elevation in tropical forests, with some species in xeric shrublands, diversifying along the Pacific slope, Central America, and north-western South America. A few species occur on the Galapagos and Revillagigedo archipelagos, some of which are endemics, whereas in the Antilles species are distributed extensively, with several endemics in the Bahamas, Cuba, Jamaica, and Hispaniola. Methods, Data from specimens in herbaria and the literature were used to construct a matrix of 104 species in 160 areas. Distributional patterns of the species of Bursera were inferred applying track analysis, parsimony analysis of endemicity (PAE), and Brooks parsimony analysis (BPA). Results, Track analysis revealed four individual tracks: (1) a circum-Caribbean track, comprising species of the Bursera simaruba species group; (2) an Antillean track, including species that have been transferred to Commiphora based on their pollen traits; (3) a Mexican Pacific track, including species of the B. fragilis, B. microphylla, and B. fagaroides species groups, called ,cuajiotes'; and (4) a Neotropical Pacific track, including the two species groups assigned to section Bullockia, in which the individual track of the Bursera copallifera species group is nested within the track of the B. glabrifolia species group. The four tracks overlap in a node in the Mexican Pacific slope, where they are highly diversified. PAE allowed us to identify 22 areas of endemism: 12 in Mexico (11 along the Mexican Pacific slope), six in the Antilles, two in Central America, one in South America, and one in the Galapagos. The general area cladogram obtained by BPA has two main clades: one includes the greater Antilles; and the other, 12 Mexican areas of endemism. Main conclusions,Bursera fragilis, B. microphylla, and B. fagaroides species groups can be treated together as a new section within Bursera, sect. Quaxiotea, because they are segregated from the other groups of sect. Bursera based on morphological, anatomical, molecular and geographical evidence. [source]

A Sea Change in Anthropology?

Public Anthropology Reviews
ABSTRACT, In this article, we introduce the inaugural issue of the "Public Anthropology Reviews" section. We suggest that the new section reflects significant changes underway in the discipline, including an expansion in the kind of work valued among anthropologists, new ways in which anthropological knowledge is being produced and disseminated, and an acknowledgment that anthropologists have a responsibility to dedicate their skills to issues of broad public import. The section will, thus, expose AA readers to some of the new anthropological work appearing in a wide variety of media and nontraditional academic formats that aims both to communicate primarily with nonanthropological audiences and to have an impact on critical issues of wide social significance. We here present the reviews in this issue, identify additional contemporary issues likely to be addressed in future reviews, and welcome submissions and critical feedback for the section. [source]

New asthma guideline The BTS/SIGN guideline for the management of asthma has been updated. The diagnosis section has been rewritten, there is a new section on difficult asthma and the treatment sections have been updated. A new option at Step 3 (initial add-on therapy) is now the use of a combined budesonide/formoterol inhaler (Symbicort) as a reliever in addition to regular use as a preventer. This reflects evidence from the SMART trials, which showed that an average of one extra puff per day significantly reduced exacerbations and admissions (Br Med J 2007;335:513). Metformin matches insulin in pregnancy Metformin does not worsen perinatal outcomes compared with insulin in gestational diabetes and mothers prefer it, a study from Australia and New Zealand shows (N Engl J Med 2008;358:2003,15). Of the women randomised to metformin treatment, 93 per cent were still taking it at term and 46 had supplemental insulin. The combined incidence of neonatal hypoglycaemia, respiratory distress, need for phototherapy, birth trauma, five-minute Apgar score less than 7 or prematurity was 32 per cent with both treatments. There were no serious adverse events. More women said they would choose the same treatment again for metformin than insulin (77 vs 27 per cent). Same CV protection with antihypertensives There is no difference in protection against major cardiovascular events between different types of antihypertensives in young or older (65 or over) adults, according to the Blood Pressure Lowering Treatment Trialists' Collaboration. Its meta-analysis of 31 trials involving over 190 000 patients (BMJ Online 2008; doi:10.1136/bmj.39548.738 368.BE) found no significant difference by age on blood pressure reduction or risk reduction. Treatment may be chosen according to tolerability and cost as long as effective blood pressure reduction is achieved, the authors conclude. Older people are at greater absolute risk and treatment therefore offers larger reductions in serious vascular events. HPV vaccination starts in September Vaccination against human papilloma virus will be part of the national immunisation programme from the start of the new school year in September. The vaccine, administered as three doses over six months, will initially be offered to girls aged 12,13 (school year 8) to reduce their risk of cervical cancer. A two-year catch-up campaign for all girls up to 18 years old will begin in 2009. MHRA: pancreatitis with exenatide warning The incretin mimetic exenatide (Byetta), licensed for the treatment of type 2 diabetes, may rarely be associated with pancreatitis, warns the MHRA (Drug Safety Update 2008;1:Issue 10). One case has been reported in the UK and 89 in the USA and Germany. The MHRA advises that patients should be warned of the symptoms of pancreatitis (severe abdominal pain, back pain). Treatment should be discontinued if pancreatitis is suspected and the case reported on a yellow card. 2007 prescribing bill Primary-care expenditure on drugs in England in 2007 totalled £8.37 billion, only 2 per cent more than in 2006, according to the latest statistics from the Information Centre ( Prescription numbers increased by almost 6 per cent. Prescribing increased in most BNF categories but changed little in musculoskeletal drugs and immunological products and vaccines. Calceos: calcium/ vitamin D3 price match Manufacturer Galen has pledged to continue to price-match its calcium/vitamin D3 supplement Calceos with Adcal-D3 or Calcichew D3 Forte. If the price of either product falls below that of Calceos chewable tablets, Galen will match it within six months. The company says it will honour the pledge until at least 2011.

Inhaled steroids for all children with asthma? Some children with mild well-controlled asthma may not need a daily inhaled steroid, a Scandinavian study suggests (Arch Dis Child 2008;93:654-9). A total of 176 children aged 5-10 years were randomised to treatment with cromoglicate (Intal) or budesonide. Initially high doses of budesonide (400,g twice daily) were reduced after one month to 200,g twice daily for four months; subsequent treatment for a further year was 100,g twice daily as required for exacerbations or 100,g twice daily regularly. Budesonide was associated with greater improvement in lung function and fewer exacerbations compared with cromoglicate, but after 18 months lung function improvements did not differ. Regular budesonide was associated with fewer exacerbations than as-required administration (0.97 vs 1.69 per patient in months 7-18) but no difference in asthma-free days or use of rescue medication. Growth suppression was slightly greater with continuous budesonide. Interventions to reduce atypicals weight gain A systematic review has found that techniques such as cognitive behaviour therapy and nutritional counselling can reduce weight gain associated with atypical antipsychotics (Br J Psychiatry 2008;193:101-7). Analysis of 10 randomised trials lasting eight weeks to six months found that nonpharmacological intervention increased mean weight loss by about 2.5kg compared with usual care. Check flu vaccine delivery Production of flu vaccine is proceeding according to plan, the Director of Immunisation has told GPs. Practices should now contact their suppliers to confirm a delivery schedule so that clinics can be arranged. New BNF for Children The fourth BNF for Children has been published, containing new sections on HPV vaccination, contraception, treatment of pelvic inflammatory disease and the use of continuous iv infusions in neonates. BNFC 2008 is available online at MMR catch-up ,urgent' The DoH has called for urgent action to reduce the risk of a measles epidemic. Following years of relatively low uptake of MMR vaccine, the pool of unprotected children is now large enough to raise the prospect of 30 000-100 000 measles cases in England. A catch-up campaign will now target children and young people who have never been vaccinated, followed by those who have not completed their course of immunisation. Resource materials are available at , A new brand of MMR vaccine is now available. Sanofi Pasteur MSD has replaced MMRII with a new formulation and presentation, MMRvaxPro. The new vaccine is equivalent to its predecessor and interchangeable with Priorix. Early primary prevention with low-dose aspirin? GPs should consider prescribing low-dose aspirin for primary prevention for men aged 48 and women aged 57, say UK researchers (Heart 2008; published online 15 August 2008. doi:10.1136/hrt.2008.150698). Using data from the THIN network of electronic patient records, they modelled the age at which 10-year coronary risk changed from <10 per cent to >10 per cent in men and women without diabetes, not taking lipid-lowering therapy and with no history of cardiovascular disease. Does COPD therapy slow progression? Treatment with an inhaled steroid and long-acting beta-agonist may slow progression of COPD, according to a new analysis of the TORCH study (Am J Respir Crit Care Med 2008;178:332-8). TORCH was designed to determine the effects of COPD treatment on mortality; the primary analysis found no significant difference between fluticasone/salmeterol (Seretide) and placebo (N Engl J Med 2007;356:775-89). This analysis found that the rate of decline in FEV1 (a marker of disease progression) was significantly greater with placebo (55ml per year) than with salmeterol or fluticasone monotherapy (both 42ml per year) or their combination (39ml per year). Faster decline in FEV1 was associated with current smoking, lower BMI and more frequent exacerbations. Copyright © 2008 Wiley Interface Ltd [source]
