Deep burrowing earthworms Lumbricus terrestris can be abundant along subdrain trenches, creating macropores that may serve as preferential flow paths for particles and agrochemicals to subdrains. We examined L. terrestris abundance, subdrain water discharge, and nutrient loss trends during 2002–2022 in an arable no-till clay soil with an emerging L. terrestris density gradient. Additionally, we analyzed subdrain water discharge during heavy rainfall events and traced material movement from topsoil to subsurface drains utilizing a 137Cs marker. Between 2003 and 2009, inoculated L. terrestris started to establish at the upper edge of the field site and successive samplings revealed gradual population growth and colonization downslope. Along the 134 m field strips (N = 2), a L. terrestris mean burrow count in 2022 reached 37 m−2 (range 29–54) with a mean individual count of 27 m−2 (13–54) at the upper edge close to the inoculation area, but on average only 5 burrows (0–8) and 2 individuals m−2 (0–8) were recorded at the lower edge. Simultaneously with L. terrestris spreading, water, sediment and nutrient discharges via subsurface drains nearly doubled. Despite these concomitant trends, statistical analyses did not support the hypothesis that long-term drainage discharges were coupled with the L. terrestris gradient. Neither were storm water discharges, nor topsoil (specifically 137Cs) migration to drains in agreement with the L. terrestris gradient. Long-term increase in discharges were likely due to increased precipitation outside the growing season (2002–2022 trend for Oct-Apr precip. +2.4 mm year−1) and increasing winter/spring temperatures (2002–2022 trend for Jan-Mar temp. +0.12 deg. year−1). Additionally, different backfill materials of the upper (topsoil) and lower (wood chips) parts of the field may have affected the results. Under the given environmental conditions and cultivation, the agronomic benefits of L. terrestris activity do not appear to come with a cost of increased subdrain leaching.

Multivariate analysis on simulated moisture damage emission to indoor air
Lappalainen, V.; Sorvari, Jouni; Sohlberg, E.; Pasanen, P.
Science of the total environment (Elsevier, 2026)
Moisture damage in buildings is a significant source of indoor air problems, releasing e.g. volatile organic compounds (VOCs) and microbially produced VOCs (MVOCs), which can cause unpleasant odors and health symptoms. However, interpreting MVOCs as indicators of mold is challenging due to their various sources and limitations in analytical methods. The objective of this study was to identify the most critical factors influencing VOC emissions from moisture-damaged wall structures into the indoor environment via structural air leakages. The research was conducted using the VTT Indoor Air Quality (IAQ) Simulator and analyzed with Principal Component Analysis (PCA). The IAQ simulator was used to investigate the transport of airborne impurities from mold-contaminated wall structures in realistic building conditions and the systematic manipulation of key environmental parameters. The resulting dataset was subjected to multivariate analysis to identify the most influential factors contributing to IAQ degradation in moisture-damaged structures. The key conclusions revealed that material relative humidity was the most significant single factor affecting all VOC concentrations; higher humidity consistently increased emissions. Four specific ketones (2-pentanone, 2-hexanone, 2-heptanone, and 2-octanone) were clearly identified as originating from microbial growth, with their concentrations being significantly higher in the presence of active mold growth. Pressure differentials had only a borderline effect on gypsum board emissions, while the insulation layer showed no significant impact on any of the identified VOC components. These findings underscore the critical role of relative humidity in determining indoor VOC profiles and highlight the value of multivariate methods in assessing mold-related indoor air problems.

Management of Biological Invasions : 1 (Regional Euro-Asian Biological Invasions Centre, 2026)
Biological invasions, driven by the spread of non-native species, have become a critical global issue because of their far-reaching ecological and socioeconomic impacts. Effective communication of the risks of biological invasions is essential for implementing robust policy and legislation and gaining public support for conservation efforts. However, current policies often suffer from fragmentation and ineffectiveness, largely due to inadequate risk communication and complex multilevel governance. To address this challenge, we develop a global framework designed to enhance clearer communication about biological invasion risks. The framework contextualizes key terms across three domains in invasion science: species invasiveness, risk analysis, and decision support tools. Using both diffusion-of-English and ecology-of-language paradigms, and following a three-step process involving preliminary consensus, AI querying, and ground-truthing with final consensus, we validate the framework in 70 non-English languages which, together with English, have official status in at least one country and collectively cover all 195 countries worldwide. Our findings reveal that while terminology for risk analysis is well established, terminology for species invasiveness and, especially, for decision Support tools remains underdeveloped in many languages, hindering effective communication and policy implementation. Our framework underscores the importance of cultural and political neutrality. By promoting clearer risk communication among scientists, policymakers, and the public globally, we aim to reduce policy fragmentation and Foster enhanced collaboration in risk mitigation. We recommend expanding multilingual decision support tools to include the full risk analysis process: risk identification, risk assessment, and risk management. This will support intergovernmental mitigation efforts and promote a unified global response to biological invasions.
