Referee3: Review of the manuscript "Reconciling single chamber Mg/Ca with whole test d18O in surface to deep dwelling planktonic foraminifera from the Mozambique Channel“ by J. Steinhardt, C. Cleroux, L. de Nooijer, G.-J. Brummer, R. Zahn, G. Ganssen, and G.-J. Reichart. This manuscript presents a large data set of single specimen stable isotopes and single chamber Mg/Ca on four species of plan...
a faunistic list of syrphidae sampled in the agroecosystems of neyshabur (khorasan-razavi province) through malaise, yellow water traps and hand net is hereby presented for the first time. a total of 22 species were collected, including 13 species through malaise trap, 5 through yellow water trap as well as representatives of all species sampled through hand net. among the species collected, 8 ...
Comprehensive field observations characterizing the biological carbon pump (BCP) provide foundation needed to constrain mechanistic models of downward particulate organic (POC) flux in ocean. Sediment traps were deployed three times during EXport Processes Ocean from RemoTe Sensing campaign at Station Papa August–September 2018. We propose a new method correct sediment trap sample contamination...
Arsenic (As) fractions in the sediments of seven lakes from East Plain Ecoregion and six lakes from Yungui Plateau Ecoregion, China, were investigated. Results indicated that the total As concentrations in sediment samples of lakes of the East Plain Lake Ecoregion are higher than those of Yungui Plateau Lake Ecoregion. Residual As is the main fraction in sediment samples of lakes from both ecor...
حدت استافیلوکوکوس اورئوس اساساً توسط پروتئینهای مرتبط با دیوارهی سلولی و ترشح توکسینها تعیین میگردد، که بیان آنها تا حد زیادی توسط سیستمهای تنظیمی دو جزئی (tcrss) مثل سیستمهای تنظیم ژنی فرعی (agr) و rap-trap تنظیم میشود. تاکنون چهار واریانت آللی از agr (agr i-iv) و trap (trap 1-4) شناسایی شده است. برخی از گزارشها اظهار داشتهاند که تمایلات بالینی بر طبق هر گروه agr وجود دارد، اما اطل...
Overland flow connectivity and runoff and sediment trap effectiveness are currently the cutting edge topics in soil erosion research. The effect of agricultural terraces, irrigation channels and trails on runoff and soil erosion modelling at catchment scale is still a remaining research question. In this study we run the index of connectivity of Borselli et al. (2008) and a modified version of ...
