An ongoing field study of the effects of elevated atmospheric CO2 on a brackish wetland on Chesapeake Bay, started in 1987, is unique as the longest continually running investigation of the effects of elevated CO2 on an ecosystem. Since the beginning of the study, atmospheric CO2 increased 18%, sea level rose 20 cm, and growing season temperature varied with approximately the same range as pred...
Planococcus maritimus MKU009 is a Gram positive cocci and a moderate halophilic bacterium isolated from marine water of Pichavaram, South East Coast of India. Here we report the draft genome of Planococcus maritimus MKU009 with a total size of 3,251,644 bp with N50 value of 1681571 bp. The overall G+C content of the genome was 47.27%. The carotenoid producing crtN, crtB, crtP and crtI genes wer...
این پژوهش برای ارزیابی کارآیی علف کش های انتخابی برنج در کنترل سوروف (echinochloa crus–galli)، جگن گرزی دریایی (scirpus maritimus)، بارهنگ آبی معمولی (alisma plantago-aquatica) و همچنین عملکرد برنج رقم محلی طارم در سال زراعی 1388 در مزرعه مؤسسه تحقیقات برنج کشور در آمل اجرا شد. تیمار های این آزمایش شامل علف کش پنوکسولام در مقادیر 24 ، 30 ، 36 ، 42 و 48 گرم در هکتار، پیش- آمیخته آنیلوفوس + اتوکس...
Recently, Mouriño et al. (2008) reported the first record in Brazil of the filamentous bacteria Flexibacter maritimus (Wakabayashi et al., 1986) from the hatching of Litopenaeus vannamei post-larvae (Boone, 1931). In our view, a generalized lack of clarity about this identification has occurred and the discussion of some issues raised in the work is beyond the scope of this commentary. As Mouri...
environmental pollution with heavy metals is a global disaster that is related tohuman activities. this study was conducted to determine the extent of heavy metalsaccumulation by plant species in lia industrial city (qazvin, iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. soil andindustrial wastewater sampling was done radially along tra...
Although tidal marshes are known for their coastal defense function during storm surges, the impact of extreme wave forcing on marsh development is poorly understood. Seedling survival in first season after germination, which may involve exposure to events, crucial natural establishment and human restoration marshes. We hypothesize that species-specific plant traits plays a significant role see...
Separation of the extract of the tubers of Scirpus holoschoenus L. (family Cyperaceae), a species easily confused with Juncus plants, afforded 2-prenyl-3,5,4'trimethoxystilbene, 2-prenyl-3-hydroxy-5,4'-dimethoxystilbene, 2-prenyl-3,4'-dihydroxy5-methoxy-stilbene and 3,5,4'-trimethoxystilbene, in addition to a new acetophenone derivative. The isolated compounds were identified on the basis of sp...
Ammonia-oxidizing archaea are ubiquitous in marine and terrestrial environments and now thought to be significant contributors to carbon and nitrogen cycling. The isolation of Candidatus "Nitrosopumilus maritimus" strain SCM1 provided the opportunity for linking its chemolithotrophic physiology with a genomic inventory of the globally distributed archaea. Here we report the 1,645,259-bp closed ...
A survey of the extracellular ATP levels of 86 heterotrophic bacteria showed that gram-negative bacteria of the genera Sulfitobacter, Staleya, and Marinobacter secreted elevated amounts of extracellular ATP, ranging from 6.0 to 9.8 pM ATP/colony forming unit (cfu), and that gram-positive bacteria of the genera Kocuria and Planococcus secreted up to 4.1 pM ATP/cfu. Variations in the levels of ex...
