| Abstract | Forests play a key role for terrestrial biodiversity. Trees are large and long-living organisms that define forest structure and form a key element in nutrient and carbon cycling. Tree species differ in ecological strategies and related functional traits, which may allow them to partition resources and coexist. It is well know that tree species differ in stem traits, but the afterlife effects of such traits for the diversity of decomposers (e.g., fungi, insects) within dead stem logs and their dynamics with ongoing decay are poorly known. To fill this knowledge gap, I studied the effects of stem traits on the infestation, composition and diversity of fungi during different phases of decay. I benefited from an existent long-term common garden decomposition experiment, called “LOGLIFE”. I showed how stem traits and related stem functions co-vary across species, and how these traits affect afterlife effects on the succession of diversity and composition of wood and bark inhabiting fungi over time, and the implications for wood decomposition. In this study, I included eight conifer and six broadleaf tree species in order to cover a wide variety of stem traits and thus explore the afterlife implications of such variation.In chapter 2 I investigated how stem traits vary across wood and bark of 14 temperate tree species, and what trait trade-offs and plant strategies are found. Stem trait variation was largely explained by major taxa and stem compartments, i.e., inner, outer wood and bark. A continuous plant strategy gradient was found across and within taxa, running from hydraulic safe Gymnosperms to conductive Angiosperms. Gymnosperms strongly converged in their trait strategies because of their uniform tracheids, whereas Angiosperms strongly diverged because of different vessel arrangement and tissue types. Bark had higher concentrations of nutrients and phenolics, whereas wood had stronger physical defence. This indicates that stem compartments fulfill different strategies; bark serves as storage organ and a first ... |

| Abstract | Dead wood is a source of life as it provides habitat and substrate for a wide range of fungal species. A growing number of studies show an important role of wood quality for fungal diversity, but in most cases for a limited number of wood traits or tree species. In this study, we evaluate how abiotic and biotic factors affect the fungal diversity and composition during dead wood decomposition. For 10 common European tree species, fresh similar-sized logs were incubated simultaneously in two Dutch forests. Annual surveys of fungal fruiting bodies were made for an 8-year period. For each tree species, 20 fresh stem traits were measured that are important for chemical and physical defence and for nutritional quality. Throughout 8 years, 4,644 fruiting bodies belonging to 255 species and 90 genera were recorded on the logs of 10 tree species. Fungal frequency and richness were higher for Angiosperms than for Gymnosperms, both for individual tree species and as a group, and higher for tree species with more acquisitive stem trait strategies (i.e., high nutritional value and low physical defence). Differences in fungal communities were strongly driven by phylogenetic group (Gymnosperms vs. Angiosperms), stem traits, decay time and forest sites, together explaining 23% of the variation. Fungal communities in sandy site diverged early in the decay process but converged later because of substrate homogenization. Of the 128 fungal species included in the analyses, 41% showed a preference for specific tree species and 34% for a specific successional year. In conclusion, dead wood quality, determined by tree species and decay stage, is an important driver of fungal diversity. For forest management, promoting a wide array of dead tree species (especially angiosperm species), a range of stem trait values and decay stages will increase fungal and, thereby, forest biodiversity. Dead wood is a source of life as it provides habitat and substrate for a wide range of fungal species. A growing number of studies show an important ... |

| Abstract | Inflammation in patients with coronary artery disease (CAD) has been linked to adverse clinical outcomes. A useful biomarker for measuring inflammation levels, high-sensitivity C-reactive protein (hs-CRP) in the blood can be used to detect the presence of low-grade inflammation. This study sought to assess the predictive value of baseline hs-CRP levels for adverse clinical events in CAD patients undergoing percutaneous coronary intervention (PCI). To investigate this topic, a meta-analysis was performed. We conducted a systematic search of PubMed, Embase, and the Cochrane Library for original articles reporting the correlation between hs-CRP levels and adverse clinical events in CAD patients undergoing PCI. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and conducted a meta-analysis by extracting relevant data. Our pooled calculations yielded hazard ratios or odds ratios with 95% confidence intervals. A total of 28 studies comprising 60544 patients were included in this analysis. High baseline hs-CRP levels predicted increased risk for major adverse cardiac events (P = 0.037), major adverse cardiac and cerebrovascular events (P = 0.020), all-cause mortality (P = 0.001), cardiovascular mortality (P < 0.001), death and/or myocardial infarction (P = 0.017) in patients, as well as restenosis (P < 0.001). However, there was no association between elevated baseline hs-CRP levels and thrombosis. In conclusion, in CAD patients undergoing PCI, baseline hs-CRP levels are reliable predictors of major adverse cardiac events, major adverse cardiac and cerebrovascular events, all-cause mortality, cardiovascular mortality, death and/or myocardial infarction, and restenosis. Therefore, hs-CRP can effectively assist in prognosis determination for CAD patients undergoing PCI. |

| Abstract | Our paper explores whether Chinese insurance companies exhibit a local preference in deciding their equity portfolios and the incentive of this preference. Our research finds that Chinese insurance institutional investors significantly tilt to invest in local firms geographically close to them, and local investments do not significantly outperform non-local investments. The results indicate that the behavioral aspect of home bias, rather than information advantage, play a more significant role in deciding equity holdings of China's insurance companies. Additionally, local equity preference is more pronounced in dialect-segmented areas and life insurance firms. This paper incorporates hometown identification into the analysis framework of insurance companies' portfolio decision-making and enriches the research of their investing strategies from the perspective of behavioral finance. |

| Abstract | Background: Increasing evidence has shown that the intestinal microbiome (IM) is highly linked to colorectal cancer (CRC). To investigate scientific output, identify highly cited papers, and explore research hotspots and trends in the field of IM/CRC, we conducted a bibliometric and visualized analysis. Methods: A bibliographic search regarding IM/CRC research (2012-2021) was implemented on October 17, 2022. The terms attached to IM and CRC were searched for in the titles (TI), abstracts (AB), and author keywords (AK). The main information was extracted from the Web of Science Core Collection (WoSCC). Biblioshiny from R packages and VOSviewer were used for data visualization. Results: A total of 1725 papers related to IM/CRC were retrieved. Publications on IM/CRC have grown rapidly from 2012 to 2021. China and the United States were in the leading position for publications in this field and made the most significant contributions to IM/CRC research. Shanghai Jiao Tong University and Harvard University were the most productive institutions. The high-yield authors were Yu Jun and Fang Jing Yuan. The International Journal of Molecular Sciences published the most papers, whereas Gut had the most citations. Historical citation analysis showed the evolution of IM/CRC research. Current status and hotspots were highlighted using keyword cluster analysis. The hot topics include the effect of IM on tumorigenesis, the effect of IM on CRC treatment, the role of IM in CRC screening, the mechanisms of IM involvement in CRC, and IM modulation for CRC management. Some topics, such as chemotherapy, immunotherapy, Conclusion: This research evaluated the global scientific output of IM/CRC research and its quantitative features, identified some significant papers, and gathered information on the status and trends of IM/CRC research, which may shape future paths for academics and practitioners. |
