The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using the maternally inherited mitochondrial A+T-rich region and bi-parentally inherited nuclear internal transcribed spacer 2 (ITS2). One hundred and eighty-seven specimens of the rice leaf roller collected from 13 Korean and Chinese localities revealed 94 A+T-rich re...
Under field conditions, species displacements have occurred in different directions between the same invasive species of leafminers (Diptera: Agromyzidae). Liriomyza sativae (Blanchard) was displaced by L. trifolii (Burgess) in the western United States, with evidence suggesting that lower insecticide susceptibility of L. trifolii is a factor. However, in Japan, the opposite has occurred, as L....
Structural changes in land use caused by urban development are one of the most important threats to ecosystem services. An in-depth study impacts that different patterns have on service value (ESV) can provide guidance for sustainable planning and ecological conservation. In this research, we sought explore response mechanisms services under scenarios from perspective “production–living–ecologi...
Iron (Fe) deficiency in crop plants is a modern agricultural problem worldwide. Although multiple strategies have been evolved to improve Fe assimilation, some plant species, especially dicots and nongraminaceous monocots (strategy I plants), cannot avoid Fe deficiency in low Fe-availability soils. It is well documented that graminaceous plants (strategy II plants) employ the chelationbased Fe ...
Few studies on population-specific health effects of extreme temperature on cardiovascular diseases (CVDs) deaths have been conducted in the subtropical and tropical climates of China. We examined the association between extreme temperature and CVD across four cities in China. We performed a two-stage analysis; we generated city-specific estimates using a distributed lag non-linear model (DLNM)...
Ride-hailing service has witnessed a dramatic growth over the past decade but meanwhile raised various challenging issues, one of which is how to provide timely and accurate short-term prediction supply demand. While predictions for zone-based demand have been extensively studied, much less efforts paid origin-destination (OD) based (namely, originating from zone another). However, OD-based eve...
This paper introduces a novel technique that uses observation data from GNSS to estimate the ionospheric vertical total electron content (VTEC) using Kriging–Kalman method. The provides method validate accuracy of Ionospheric VTEC analysis within Equatorial Ionization anomaly region. developed alongside solar parameters, such as radio flux (F10.7 cm), Disturbance Storm Time (Dst) and other data...
