Soil resource availability is much more important than soil resource heterogeneity in determining the species diversity and abundance of karst plant communities

open access: yesEcology and Evolution, Volume 11, Issue 23, Page 16680-16692, December 2021., 2021
Both limited resource availability and significant resource heterogeneity are key features of karst landscapes. Our study first considered simultaneously resource availability and heterogeneity in karst regions and then quantified and compared the effects of resource availability and heterogeneity on community abundance and species diversity from the ...

Phylogenetic significance of the characteristics of simple sequence repeats at the genus level based on the complete chloroplast genome sequences of Cyatheaceae

open access: yesEcology and Evolution, Volume 11, Issue 20, Page 14327-14340, October 2021., 2021
Whether chloroplast genome SSRs can be used to classify Cyatheaceae species has not yet been studied. Therefore, the chloroplast genomes of eight Cyatheaceae species were sequenced by our team, and their SSR characteristics were compared and statistically analyzed.

Effects of Underlay on Hill-Slope Surface Runoff Process of Cupressus funebris Endl. Plantations in Southwestern China [PDF]

open access: yesForests, 2021
Clarifying the impact of underlay (i.e., the combination of near-surface vegetation and surface micro-topography) on the surface runoff process would provide a significant theoretical basis for the adjustment of vegetation patterns and the control of soil erosion on steep slopes in mountainous areas of southwestern China.

Evolutionary legacy of a forest plantation tree species (Pinus armandii): Implications for widespread afforestation

open access: yesEvolutionary Applications, Volume 13, Issue 10, Page 2646-2662, December 2020., 2020
Abstract Many natural systems are subject to profound and persistent anthropogenic influence. Human‐induced gene movement through afforestation and the selective transportation of genotypes might enhance the potential for intraspecific hybridization, which could lead to outbreeding depression.

List of non‐EU Scolytinae of coniferous hosts

open access: yesEFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health prepared a list of non‐EU Scolytinae spp. (Coleoptera: Curculionidae) affecting coniferous hosts. A literature review and search of databases, conducted up to January 2019, identified 804 Scolytinae species and subspecies of coniferous hosts. These Scolytinae were

Phylogeography and allopatric divergence of cypress species (Cupressus L.) in the Qinghai-Tibetan Plateau and adjacent regions

open access: yesBMC Evolutionary Biology, 2010
Background Although allopatric speciation is viewed as the most common way in which species originate, allopatric divergence among a group of closely related species has rarely been examined at the population level through phylogeographic analysis.
