Crab grows by periodic molting, which is controlled by molt-inhibiting hormone (MIH) and ecdysteroids. Untranslated regions (UTRs) play crucial roles in the posttranscriptional regulation of gene expression. In this study, using crab collected from Changjiang (Yangtze), Huanghe (Yellow), Liaohe, and Yalujiang rivers, 33 haplotypes of the 3ꞌ-UTR of ecdysteroid-regulated protein (ERP) gene were i...

The structure of caprocks is often greatly altered by different scales faults or fissures in long-term geological tectonic evolution, and the sealing performance may be deteriorated. In this paper, a simplified model characterized as multilayered sandstone fault-bearing extracted from Shuang 6 underground gas storage located Liaohe oilfield was established. Different fault geometry (e.g., lengt...

Increasing pressure on water supply worldwide, especially in arid areas, has resulted in groundwater overexploitation and contamination, and subsequent deterioration of the groundwater quality and threats to public health. Environmental risk assessment of regional groundwater is an important tool for groundwater protection. This study presents a new approach for assessing the environmental risk...

Recently, the economic traits of Chinese mitten crab (Eriocheir sinensis) varieties have had a negative tendency. Meanwhile, status wild germplasm resources E. sinensis is unknown, hindering utilization and green development industry. Thus, conservation resource great significance. To this end, we collected from two different river basins, Yangtze River basin, Liaohe analyzed genetic diversity ...

Accurate digital mapping of farmland soil organic carbon (SOC) contributes to sustainable agricultural development and climate change mitigation. Farmland landscape pattern has changed greatly under anthropogenic influence, which should be considered an environmental variable characterize the impact human activities on SOC. In this study, we verified feasibility integrating patterns in SOC pred...
