Holotrichia oblita Faldermann (Coleoptera: Scarabaeidae) is a major pest both in field crops and forests because the larvae could eat the roots of most crops in the field, and the adults damage the leaves of trees and field crops. In this study, we focused on the effects of temperature on H. oblita reproductive parameters. The results indicated H. oblita female adults at 25 °C could lay more eg...
Carbon (C) budget at cropping systems has not only agronomic but also environmental relevance because of their contribution to both emissions and removals greenhouse gases (GHGs). Ideally, sustainable orchards are expected remove atmospheric CO2 a rate greater than that the (i) optimized biology system (ii) reduced on-site/offsite inputs sourced by technosphere. However, such computation might ...
Crop rotation has been practiced for centuries in an effort to improve agricultural yield. However, the directions, magnitudes, and mechanisms of the yield effects of various crop rotations remain poorly understood in many systems. In order to better understand how crop rotation influences cotton yield, we used hierarchical Bayesian models to analyze a large ecoinformatics database consisting o...
