Aim: Understanding the effects of habitat degradation on biodiversity is essential for undertaking conservation initiatives, but commonly used metrics of biodiversity, like species richness and beta diversity, can miss important signals of change. Greater insights can be gained by partitioning beta diversity into nestedness, which relates to species loss, and turnover, which relates to species replacement. To obtain a more comprehensive understanding of biodiversity change with habitat degradation, we investigate how nestedness and turnover vary when comparing assemblages from the same or different habitat degradation levels, and how assemblage aggregation resolution influences this relationship. Location: Sweden. Methods: We used beta diversity partitioning to assess lichen, fungi and bryophyte species composition from 120 forest sites across Sweden, from three different habitat degradation levels, and at two aggregation scales (pairwise local assemblages and assemblages pooled at the habitat degradation level across our study sites). We examined how pairwise total beta diversity, nestedness and turnover varied when comparing assemblages from sites of either the same or different habitat degradation levels. In addition, we examined the relationship between total beta diversity, nestedness and turnover when assemblages pooled at the habitat degradation level were compared. Results: We detected a small increase in pairwise lichen total beta diversity (Cliffs delta 0.40) and nestedness (Cliffs delta 0.19), but not in any other pairwise comparisons. In contrast, for all taxa, comparisons between assemblages pooled at the habitat degradation level showed higher values of nestedness and lower values of turnover than the corresponding pairwise comparisons, suggesting biotic homogenisation in highly degraded sites. Main Conclusions: Our results highlight the importance of considering biodiversity change across multiple spatial resolutions to fully capture the effects of local species replacements in highly degraded habitats on biotic homogenisation.

Sustainability : 17 (MDPI, 2025)
In advanced economies, most food waste occurs at the downstream stages of the supply chain; within the EU, it has been estimated that 64.57% of food waste occurs at the consumption stage, with about 5.4 million tons (9.45% of the total) being generated in food service. This study aims to contribute to this stream of research by providing evidence about the quantity of food waste produced in Italian primary schools and discussing the results against the evidence available in other EU countries. This research is based on a large-scale study involving 78 primary schools and over 11,000 students for a total number of almost 110,000 monitored meals. The results show that the amount of food not consumed at lunch is 21.7% of the food prepared every day. Plate waste accounts for almost 90 g/day per capita and the total amount of wasted food, including unserved food, accounts for 117 g/day per capita. To our knowledge, this study represents the largest sample size monitored in Italy under the framework of the EC Delegated Decision (EU) 2019/1597 on food waste measurement. Given its scale and adherence to the EU’s standardized methodology, this dataset should serve as the reference data for Italy reported to Eurostat, as it is based on direct measurements rather than estimates or secondary data sources. This underscores the importance of systematic, comparable data collection for tracking progress on food waste reduction at both national and European levels.
From surplus to sustainability: The role of legislation in reducing climate impact from Swedish bread waste

Current research in environmental sustainability (Elsevier, 2025)
Food waste infers considerable environmental, social, and economic consequences. While previous research has focused on interventions at the supplier-retailer interface to reduce surplus, this paper explores the reduction potential in applying legal instruments and evaluates the climate benefits of enforcing four different policy measures: 1) Prohibiting Unfair Trading Practices; 2) Advancing Redistribution of Surplus; 3) Enforcing Best Available Technology; and 4) Legally binding reduction targets. Applied to the case study of bread in Sweden, the results clearly show that, through the enforcement of binding regulations or market-based mechanisms, surplus could be reduced by 6–50 %, while also lowering climate impact with up to 18 % compared to the current system. The results illustrate how Sweden can optimize its bread supply chain through regulatory and market-based strategies, with applicability on an international scale. These findings also highlight the potential in combining legislation and economic incentives to optimize the conventional bread supply chain, for reduced waste and improved surplus management. By demonstrating the benefits of enforcing different legislations and policy measures, the results can be used to further develop and enforce targeted policy recommendations and legislations for reduced food waste. While the scenarios explored are specific to the bread supply chain, the insights gained are applicable to other perishable food sectors facing similar waste management challenges.
