摘要:... A clonal seed orchard (CSO) was established including potentially genetically differentiated provenances from the whole distribution area, we applied nine simple sequence repeat (SSR) makers to study the genetic diversity and population structure of six maternal populati...

摘要:... However, the abundance, diversity and succession of denitrifying bacteria and their association with farming systems are largely unknown. Therefore, the objectives of the present study were: (1) to unravel the influence of long-term organic farming on diversity of nirK -...

摘要:Abstract(#br)A global meta-analysis was conducted to evaluate the effect of conservation tillage practices on soil microbial population size [based on microbial count and phospholipid fatty acid (PLFA) measurements], diversity (Shannon index), and microbial community structur...

摘要:Abstract(#br)Increasing evidence suggests that ecosystem functions are strongly linked to morphological plant traits, like specific leaf area (SLA) and its variability, which serve as a proxy of functional diversity (FD). Functional diversity is rarely studied at regional scal...

摘要:... The principle of incorporating genetic diversity information into founder selection for species reintroductions is widely recognized; however, in practice, a full assessment of available ex-situ genetic variation is rarely attempted prior to identifying individuals for releas...

摘要:... After 1 month of exposure, the abundances of meiobenthic taxa and the taxonomic and morpho-functional diversity of nematodes showed significant differences between the Spirulina and Spirulina + chromium groups. The nematodes were more tolerant of all types of stressors compar...

摘要:Abstract(#br)Despite being introduced to the Caribbean over 227 years ago to address issues of food insecurity, breadfruit ( Artocarpus altilis ) has remained underutilized, which has been linked to the limited knowledge of the crop diversity and characterization in the region. A...

摘要:... however, their molecular diversity and distribution patterns in the deep-sea seamounts and abyssal plains of the tropical Western Pacific Ocean are poorly known. In this study, using next-generation sequencing, we investigated the molecular diversities and community compositi...

摘要:... In this paper, spider diversity and its plant hopper control potential were assessed in paddy fields cultivated organically for 5 (OR5), 10 (OR10) and 15 (OR15) years and in conventional paddy fields (CR). The results showed that the abundance, richness and Pilou evenness of ...
