Distributions of non‐native and native plants are not determined by the same environmental factors
Published 2024-10-01“…In the framework of correlative species distribution models, we used newly developed methods for efficient automated selection of a parsimonious number of predictor environmental variables to determine which ones, out of a large candidate set in eight classes, have the strongest explanatory power for both species groups. …”

Pretreatment method of forchlorfenuron residues in loquat by HPLC analysis
Published 2016-05-01“…Therefore, residue detection of forchlorfenuron in fruits and vegetables is imperative.High-performance liquid chromatography (HPLC) analysis is a common detection method. The suitable conditions for the extraction and purification of sample play an important role prior to HPLC analysis.In this study, the extraction efficiency of forchlorfenuron residues in loquat was compared using matrix dispersive solid phase extraction and QuEChERS (quick, easy, cheap, effective, rugged, safe).The results showed that QuEChERS was a more suitable pretreatment method for the determination of forchlorfenuron residues in loquat, because it had obviously higher average recoveries than the matrix dispersive solid phase extraction. …”
