Abstract. The patterned microtopography of subarctic mires generates a variety environmental conditions, and carbon dioxide (CO2) methane (CH4) dynamics vary spatially among different plant community types (PCTs). We studied the CO2 CH4 exchange between fen atmosphere at Kaamanen in northern Finland based on flux chamber eddy covariance measurements 2017–2018. observed strong spatial variation ...
Leaf rust is a devastating disease in wheat crop. The forecasting models can facilitate the economic and effective use of fungicides assist limiting crop yield losses. In this study, six cultivars were screened against leaf at two locations, during three consecutive growing seasons. Subsequently, stepwise regression analysis was employed to analyze correlation epidemiological variables (minimum...
Globally, vegetable fields are the primary source of greenhouse gas emissions. A closed-chamber method together with gas chromatography was used to measure the fluxes of nitrous oxide (N2O) emissions in typical vegetable fields planted with four vegetables sequentially over time in the same field: endive, lettuce, cabbage and sweet corn. Results showed that N2O fluxes occurred in pulses with th...
UNLABELLED It is well known that rhizosphere microbiomes differ from those of surrounding soil, and yet we know little about how these root-associated microbial communities change through the growing season and between seasons. We analyzed the response of soil bacteria to roots of the common annual grass Avena fatua over two growing seasons using high-throughput sequencing of 16S rRNA genes. Ov...
background: fasting during the holy month of ramadan (fasting) for muslims is a religious duty. the impact of fasting on some diseases has been reported in medical literature. this study evaluated the effects of fasting on appendicitis. in this population-based descriptive study, we investigated whether the incidence of acute appendicitis differs during fasting compared to other non fasting lun...
Warming and drought alter plant phenology, photosynthesis growth with important consequences for the global carbon cycle earth's climate. Yet, few studies have attempted to tease apart their effects on tree particularly leaf senescence, source sink activity. We experimentally assessed single combined of warming reduced soil moisture phenology (leaf-out senescence date, growing season length) ab...
