Interplays between plants and environmental factors determine pullout resistance on different revegetated slopes in mining areas.

Plant roots play a crucial role in enhancing soil stability and protecting slopes during ecological restoration, particularly in mining areas where external-soil spray seeding is employed. However, the relationship between plant root pullout resistance and environmental factors on different types of slopes remains unclear. In this study, we investigated the interactions between the pullout resistance of a dominant species, Artemisia gmelinii, and environmental factors on three slope types (rocky, geotechnical, and soil) using multi-group structural equation modeling.

[Plant diversity on different types of slope ecological engineering and its responses to environmental factors in mining areas.].

With three types of ecological slope protection projects of rock slope, soil slope and rock soil mixed slope (geotechnical slope) in Xishan mining area of Taiyuan as the object, CCA ranking was used to examine the relationship between environmental factors and species distribution of different types of slopes, and analyze the impacts of environmental factors such as soil and topography on plant diversity. The results showed that geotechnical slope was rich in vegetation composition (8 families, 17 genera, and 19 species), including Asteraceae, Gramineae, Fabaceae, Vitaceae, Lamiaceae, Simaroubaceae, . The species richness, Shannon index, Simpson index, and Pielou evenness index of the geotechnical slope were significantly higher than that of soil slope and rocky slope.

Complete chloroplast genome of (Sapindaceae), a tertiary relic rare tree.

The dioecious relic is a tertiary relict and only species of its genus within the family Sapindaceae. Using an Illumina platform, we sequenced its complete chloroplast (cp) genome. Our study reveals that has a typical cp genome of 158,537 bp in length, comprised of a large single-copy region (LSC) of 86,693 bp, a small single-copy region (SSC) of 18,012 bp, and two inverted repeat regions (IRs) of 26,916 bp, respectively.
