1. Biodiversity is an important component of natural ecosystems, with higher species richness often correlating with an increase in ecosystem productivity. Yet, this relationship varies substantially across environments, typically becoming less pronounced at high levels of species richness. However, species richness alone cannot reflect all important properties of a community, including community evenness, which may mediate the relationship between biodiversity and productivity. If the evenness of a community correlates negatively with richness across forests globally, then a greater number of species may not always increase overall diversity and productivity of the system. Theoretical work and local empirical studies have shown that the effect of evenness on ecosystem functioning may be especially strong at high richness levels, yet the consistency of this remains untested at a global scale. 2. Here, we used a dataset of forests from across the globe, which includes composition, biomass accumulation and net primary productivity, to explore whether productivity correlates with community evenness and richness in a way that evenness appears to buffer the effect of richness. Specifically, we evaluated whether low levels of evenness in speciose communities correlate with the attenuation of the richness–productivity relationship. 3. We found that tree species richness and evenness are negatively correlated across forests globally, with highly speciose forests typically comprising a few dominant and many rare species. Furthermore, we found that the correlation between diversity and productivity changes with evenness: at low richness, uneven communities are more productive, while at high richness, even communities are more productive. 4. Synthesis. Collectively, these results demonstrate that evenness is an integral component of the relationship between biodiversity and productivity, and that the attenuating effect of richness on forest productivity might be partly explained by low evenness in speciose communities. Productivity generally increases with species richness, until reduced evenness limits the overall increases in community diversity. Our research suggests that evenness is a fundamental component of biodiversity–ecosystem function relationships, and is of critical importance for guiding conservation and sustainable ecosystem management decisions.

Abstract
This article reports findings from two research projects that aimed to understand the vulnerabilities of cultural heritage sites in Svalbard and investigated factors that influence tourism-induced pressures and site degradation. It draws upon fieldwork conducted at ten selected historic locations, including interviews with tourists and guides, consultations with regional and central cultural heritage management authorities, on-site observations, and condition assessments. The primary goal was to explore indicators rendering cultural heritage sites susceptible to the impacts of tourism and human visitors. These indicators were common denominators and encompassed the sites’ physical state/degree of decay, legibility, accessibility, and quantity and quality of objects at the sites. This article seeks to enhance the understanding of these sites’ vulnerabilities and provide insights for effective heritage site management and sustainable tourism development. The principal findings highlight key factors contributing to cultural heritage sites’ vulnerability. These factors encompass intensity and frequency of visitor traffic, suboptimal visitor management strategies, tourists’ limited awareness of proper site behaviour and conservation practices, and restricted resources for site maintenance and protection. These findings can guide policymakers, site managers, and tourism stakeholders in formulating strategies to balance tourism promotion with site conservation, ensuring the long-term preservation of cultural heritage in this unique and vulnerable environment.
