    Biological conservation (Elsevier, 2026)
    Remote tracking of animals complements traditional marking and recapture methods across ecological studies, improving estimates of demographic rates, migration connectivity, habitat selection, and social interactions. Its insights into how individual behaviour scales up to population dynamics are especially critical for effective transnational conservation, particularly for threatened migratory species. Here, we synthesise over two decades of GPS tracking data from 626 Eurasian curlews (Numenius arquata) to assess how movement ecology informs conservation and policy for this species of high conservation concern across Europe. We show how tracking has refined our understanding of migration connectivity, demography, and habitat selection, and how it can be translated into actionable insights for conservation. Tracking data provided unprecedented information confirming strong site fidelity among adult curlews and evidence of local recruitment. It highlights the importance of young birds' survival until they become reproductively mature and recruit for the population dynamics, and therefore the need for appropriate conservation measures. At the same time, this review shows how movement data contributes to or can contribute to characterize most of the threats to curlews, such as human disturbance or the development of human infrastructure. These findings translate into policy recommendations, including habitat protection, network-based conservation of migratory nodes, mitigation of anthropogenic threats, and the strategic use of population reinforcement. Overall, this synthesis highlights the critical role of individual-based tracking in bridging ecological knowledge and conservation action and provides guidance for the future use of tracking data to improve the conservation status of the Eurasian Curlew along its flyway.

    The recent decline in forest carbon (C) sink across the Nordic countries has been partly attributed to increased water limitations, that is, droughts, on forest productivity. However, empirical evidence for this remains limited. This study combines ERA5-Land reanalysis datasets with long-term C and water flux observations from Swedish and Finnish coniferous forest eddy covariance (EC) towers to assess the conditions under which atmospheric (high vapor pressure deficit, VPD) and soil droughts (low soil moisture) have affected forest carbon uptake. Using the reanalysis datasets, we then evaluate whether such conditions have become more common at the studied sites, and across northern Europe in general. EC data suggests that C and water exchange has responded only to extremely low soil moisture, whereas the response to atmospheric droughts has been more gradual and the strongest response occurred during compound droughts. At two sites, isolated drought years led to over 10% reduction in annual gross primary productivity and 20%–40% decline in annual net ecosystem productivity. However, frequent and widespread impacts on annual C fluxes were not observed. The occurrence of atmospheric droughts has increased across northern Europe during the last decade, while soil and compound droughts showed more localized changes. Beyond methodological advances in analyzing drought signals from EC data, our results shed light on how droughts may have influenced ecosystem–atmosphere carbon and water fluxes across northern European forests by integrating site-level flux responses with reanalysis datasets. The results suggest that increasing VPD may be one underlying factor for the observed decline in forest growth in the Nordic countries, while soil moisture limitations have been likely rarer and more local.

    Objective: The ‘Food Insecurity among European University Students during the COVID-19 Pandemic’ (FINESCOP) study investigates food insecurity (FI) and factors associated with FI among university students in nine European countries. Design: A cross-sectional, web-based survey design was employed. The Food Insecurity Experience Scale (FIES) was used for standardised assessment of FI across the study sites. Setting: The study was conducted at nine universities in different European countries. Participants: A total of 3250 cases were included in the joint analysis, with FI assessed using the standardised FAO-developed FIES. Results: The findings reveal considerable regional disparities in FI, with moderate or severe FI (FImod + sev) prevalence rates ranging from 3·1 % at an Italian university to 32·1 % at Ege University in Türkiye. Seven out of nine universities had FImod + sev prevalence rates above 10 %, exceeding the European 3-year average (2021–2023) of 7·8 %, with rates in most universities surpassing their respective national populations. Logistic regression analysis controlling for country-level fixed effects highlighted factors associated with higher odds of FI, including being born outside Europe, lower parental education, reliance on student loans and receiving food assistance. Conclusions: While the FIES provides standardised assessments across diverse contexts, the survey’s timing during the COVID-19 pandemic may limit the findings’ generalisability to non-pandemic periods. Future research should adopt longitudinal designs and refine the FIES to enhance its applicability in diverse settings. This study emphasises that university students in Europe have unique vulnerabilities to FI, which must be recognised to create effective interventions and further research into its structural causes.
  • Do shrubs destroy or build peat soil carbon pools?

    Soil biology and biochemistry (Elsevier, 2026)
    Dwarf shrubs naturally form dense growths in some peatland types, but their presence is increasing and spreading across the Northern Hemisphere due to climate change. Their role as ecosystem engineers – particularly through their symbiotic ericoid mycorrhizal fungi – has been explicitly recognized in peatland ecology only recently. However, whether they build or destroy peat carbon pools remains debated, with contrasting evidence suggesting that shrubs may enhance either the decomposition or stabilization of peat carbon pools. Regardless of whether shrubs are “bad” or “good” for peat carbon storage, the mechanisms through which they influence peat carbon pools remain the same. Shrubs modify soil carbon and nutrient cycling via inputs of above- and belowground litter, leachates, root exudates, and the plant-soil interactions mediated by their fungal partners. We postulate that the shrub effect on peatland carbon pools depends on the shrub species and/or the environment they grow in. In this perspective, we identify key knowledge gaps related to shrub effects and emphasize the need to better account for variation in shrub functional traits and environmental context. Understanding how shrubs shape their peaty environment is basic knowledge that is, unfortunately, lacking, despite being essential for predicting how shrubs shape peatland carbon dynamics under the ongoing climate change.
