We describe four patients from three independent families with the m.1644G>A in the MT-TV gene, previously reported without demonstration of its deleterious impact. Very high mutation proportion co-segregated with cytochrome oxidase defect in single muscle fibers and respiratory defect in cybrids as shown by spectrophotometric assays and polarography. The mutation appeared to have a very steep ...
During flood events, river topography and fluvial habitats can change drastically, potentially affecting the ecological status. In case of multiple floods, whether each single event modifies habitat characteristics in same direction or not, is still an open question. We gathered high quality topographical data one braided Alpine reach before, between after floods. Considering full dynamics hydr...
Fragmentation is recognized as one of the main factors affecting species and functionality losses in tropical landscapes. In this study, we assess how landscape quality quantity affect taxonomic functional diversities carbon stocks Atlantic Forest. We used a large dataset, which comprises 92,754 adult trees 668 species, distributed over an area 95,733 km2 state Santa Catarina, southern Brazil...
مطالعه حاضر با هدف شناسایی فونستیک پرندگان و مقایسه تنوع گونه ای جامعه پرندگان بین زیستگاه های مختلف شهرستان نقده انجام گرفت. برای این منظور پرندگان منطقه مورد مطالعه از تیرماه 1389 تا خرداد 1391 در چهار زیستگاه استپ های نیمه خشک، تالابی، کشاورزی و کوه های مرتفع پایش گردید. برای بررسی اهمیت هریک از زیستگاه ها برای پرندگان، شاخص های تنوع گونه ای زیستگاه ها مورد مقایسه قرار گرفت. در مجمو...
