    Phylogenies based on ITS and LSU nrDNA sequences show Agaricus (Gymnopus) acervatus as unique within the Gymnopus/Rhodocollybia complex. These phylogenies imply that a separate genus is necessary, and Connopus is proposed. Infraspecific morphological and DNA-based variation within C. acervatus suggests that a western North American clade might be reproductively isolated from the eastern North American/Scandinavian clade and that in this species complex the European and eastern North American clade might be conspecific. A Scandinavian exemplar is selected for bar-coding. Two GenBank sequences with name-phylogenetic placement inconsistencies are identified

    Fatal Pulmonary Embolism in a 10-Year Old With Nephrotic Syndrome

    We present a case report of a 10-year-old male with nephrotic syndrome who presented with a complaint of shortness of breath. The patient had been recently hospitalized for an exacerbation of nephrotic syndrome and had received steroid and diuretic therapy. Initial vital signs showed tachycardia and mild tachypnea. After being observed for more than four hours without deterioration he was discharged home for close follow up. The patient returned 4 hours later with worsening symptoms and went into cardiac arrest in the ED. Autopsy revealed bilateral large pulmonary emboli. Pulmonary embolism is a known complication of nephrotic syndrome. Hyperviscosity occurs due to a variety of mechanisms. Nearly all reported incidents are associated with the use of steroids and diuretics. It is essential to maintain a heightened suspicion of pulmonary embolism (PE) when children with nephrotic syndrome present with pulmonary complaints, particularly when they have been treated with steroids and diuretics

    Predicting distributions of known and unknown reptile species in Madagascar

    Despite the importance of tropical biodiversity(1), informative species distributional data are seldom available for biogeographical study or setting conservation priorities(2,3). Modelling ecological niche distributions of species offers a potential soluion(4-7); however, the utility of old locality data from museums, and of more recent remotely sensed satellite data, remains poorly explored, especially for rapidly changing tropical landscapes. Using 29 modern data sets of environmental land coverage and 621 chameleon occurrence localities from Madagascar ( historical and recent), here we demonstrate a significant ability of our niche models in predicting species distribution. At 11 recently inventoried sites, highest predictive success (85.1%) was obtained for models based only on modern occurrence data (74.7% and 82.8% predictive success, respectively, for pre-1978 and all data combined). Notably, these models also identified three intersecting areas of over-prediction that recently yielded seven chameleon species new to science. We conclude that ecological niche modelling using recent locality records and readily available environmental coverage data provides informative biogeographical data for poorly known tropical landscapes, and offers innovative potential for the discovery of unknown distributional areas and unknown species.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62843/1/nature02205.pd
