The probability of falling likely differs among taxa based on their adhesive capacities and ability to anticipate disturbance. We quantified the motion of red oak (Quercus rubra Linnaeus [Fagales: Fagaceae]) leaves, and the composition of arthropods dislodged from woody vegetation, following disturbance mimicking branch landings by eastern gray squirrels (Sciurus carolinensis Gmelin [Rodentia: Sciuridae]). Simulated squirrel landings caused terminal leaves on red oak branches to move rapidly (up to 100 cm s^-1) upward and inward toward the tree trunk during the first 50 ms, and dislodged 30% of the arthropods present on a branch. The composition of fallen arthropods was similar to those that remained on the branches, but the proportion dislodged differed among taxa. We used a small catapult to test the effect of leaf movement on the adhesive capabilities of workers of the carpenter ant Camponotus pennsylvanicus DeGeer (Hymenoptera: Formicidae). Arboreal ants presumably anticipate disturbance; thus, they were either \"warned\" or \"unwarned\" before each launch. Most ants (98%) were dislodged by the catapult. Warning did not affect the average (± SE) initial velocity (126.0 ± 72.0 cm s^-1) or maximum height (22.8 ± 9.3 cm) of launched ants. However, both variables were positively associated with ant mass. The results illustrate the limited ability of many arboreal arthropods to avoid the consequences of a common natural hazard and improve our understanding of the challenges imposed by an arboreal lifestyle.</p>","PeriodicalId":794,"journal":{"name":"The Science of Nature","volume":"112 3","pages":"42"},"PeriodicalIF":2.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite growing recognition of spillovers, they remain unevenly defined, inconsistently measured, and poorly integrated into policy evaluation and accountability frameworks. This systematic review synthesizes current research on land-use spillovers triggered by environmental policies, including carbon pricing, protected areas, supply chain interventions, and payments for ecosystem services. We identify three dominant pathways: leakage, indirect land use change (iLUC), and positive spillovers, emerging under common conditions such as weak enforcement, market integration, limited livelihood alternatives, and accessible frontier lands. These conditions are shaped by broader institutional, economic, demographic, and biophysical drivers, yet are rarely integrated into policy design and evaluation. While methods to evaluate spillover effects range from global scale ex ante models to local ex post spatial and econometric analyses, few studies bridge scales or connect findings to international policy frameworks such as the Convention on Biological Diversity (CBD) or the United Nations Framework Convention on Climate Change (UNFCCC). Cases are concentrated in climate-linked interventions and in South America, leaving important geographic and sectoral blind spots. This limits their relevance for designing policies that minimize displaced impacts and foster more durable outcomes. Advancing spillover research will require common frameworks, more consistent methodologies, and multi-scale tools that can enhance comparability, attribution, and integration into environmental governance.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"92 ","pages":"Article 103013"},"PeriodicalIF":8.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attributing biodiversity loss to domestically consumed versus internationally traded agricultural production is vital to make supply chains more transparent and sustainable. However, such an attribution is challenging due to the complexity of agricultural supply chains and the lack of tools and data. Here, we attributed biodiversity decline in the Gran Chaco, specifically the Argentinian and Paraguayan Chaco, to both soy and beef agricultural commodities and the domestic and foreign demand for these. We integrated three sources of multitemporal data at a subnational scale (data on mammal diversity, land use change and commodity trade) to first differentiate pasture- versus cropland-driven biodiversity decline and second, to assess the share of the decline associated with domestically consumed and internationally traded Argentinian and Paraguayan soy and Paraguayan beef. In doing so, we provided four novel insights. First, pasture expansion had a greater relative biodiversity impact than cropland expansion. Second, the biodiversity decline associated with domestic and international consumption depended on both the quantity of imports and the precise location of production and sourcing. Third, domestic consumption of commodities in Argentina and Paraguay was associated with a much greater risk of driving decline in biodiversity than agricultural exports from these nations. Fourth, considering only one facet of biodiversity risks underestimating the decline in biodiversity linked to agricultural expansion and commodity supply chains. By connecting agriculturally driven biodiversity decline in the Gran Chaco to commodity supply chains, we highlight the importance of increasing the transparency of supply chains to make them more sustainable. Doing so will be critical to prevent further biodiversity loss in not only the Gran Chaco but also the other dry forests of the world.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"92 ","pages":"Article 103011"},"PeriodicalIF":8.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that Cd concentrations in soils from mining areas were significantly higher than those in control areas (<i>p</i> &lt; 0.01), while Hg concentrations showed no significant difference.
