(1) Background: soil salinization has become a global problem that restricts agricultural production; thus, there is need to explore the special survival strategies of halophytes in saline–alkali environments. (2) Methods: this study conducted comparative analysis differences metabolites and mineral elements between two indicator plants (Suaeda glauca Suaeda salsa) area. (3) Results: S. salsa l...

LiDAR technology can provide very detailed and highly accurate geospatial information on an urban scene for the creation of Virtual Geographic Environments (VGEs) for different applications. However, automatic 3D modeling and feature recognition from LiDAR point clouds are very complex tasks. This becomes even more complex when the data is incomplete (occlusion problem) or uncertain. In this pa...

Salinization is an important and increasingly prevalent issue which has broad and profound effects on plant survival and distribution pattern. To understand the patterns and potential drivers of leaf traits in saline environments, we determined the soil properties, leaf morphological traits (specific leaf area, SLA, and leaf dry matter content, LDMC), leaf chemical traits (leaf carbon, C, nitro...

With the development of computer science, communications technology and environmental modeling, virtual geographic environments (VGEs) have been linked with field observations and geographic modeling. VGEs enable researchers in various fields to collaboratively perform computer-aided geographic experiments. This study proposes a collaborative environment to conduct a virtual flood experiment th...

VGE geographic knowledge refers to the abstract and repeatable geo-information which is related to the geo-science problem, geographical phenomena and geographical laws supported by VGE. That includes expert experiences, evolution rule, simulation processes and prediction results in VGE. This paper proposes a conceptual framework for VGE knowledge engineering in order to effectively manage and ...

The authors investigated the influence of associative pairing of contextual stimuli with amphetamine administration on the expression of psychomotor sensitization. Animals received d-amphetamine or saline in group-specific environments. Amphetamine produced robust behavioral sensitization in all environments, but when an amphetamine challenge was given in a test environment that was novel for s...
