Tea Bag Index Revisited: Risks of Misleading Decomposition Patterns

Ecology Letters, Journal Year: 2025, Volume and Issue: 28(4)

Published: April 1, 2025

ABSTRACT This study shows that recent global analyses using the Tea Bag Index (TBI) are influenced by methodological flaws: (1) interdependence of stabilisation factor ( S ) and decomposition constant k biases correlation analysis, (2) derivation from separate curves causes their decoupling, most importantly, (3) determination is inaccurate.

Impact of Mining Tailings on Soil Decomposition and Carbon Stabilisation in a Riparian Atlantic Forest

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 20, 2025

This study investigates the impacts of mining tailings on soil decomposition processes in a riparian Atlantic Forest ecosystem, focusing Samarco dam disaster Brazil. Understanding these is vital for restoration and management contaminated environments. We employed Tea Bag Index method to measure rates (k) stabilisation factors (S) at reference sites across different seasonal conditions. Soil chemical physical properties were analysed determine their influence processes. Results indicated significantly lower soils compared sites, particularly during wet conditions mid-incubation periods. The factor was soils, suggesting reduced capacity carbon sequestration. Seasonal variations affected dynamics, highlighting complex interactions between environmental contamination. underscores profound impact ecological functions, stabilisation. These findings are crucial developing strategies mitigate such disturbances enhance resilience recovery ecosystems.

Cones and consequences: the false dichotomy of conifers vs broad‐leaves has critical implications for research and modelling

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: April 22, 2025

Summary In plant science research and modelling, particularly from the northern hemisphere, terms ‘needle‐leaved’ ‘conifer’ along with ‘broad‐leaved’ ‘angiosperm’ are often used synonymously, creating false dichotomy that conifers needle‐leaved angiosperms broad‐leaved. While these equivalences may be largely correct in temperate they do not hold true equatorial southern hemisphere forests. Confounding broad‐leaved present significant issues empirical modelling. Here, we highlight likely origins impacts of misusing conifer‐related terminology, misinterpretation ensues its implications. We identify issue a focus on Pinaceae coin term ‘Pinaceae panacea’ to describe this. provide recommendations for future research: standardising use definitions shifting away using as model group all conifers.

Vulnerability of Labile Organic Matter to Eutrophication and Warming in Temperate Mangrove Ecosystems

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(2)

Published: Feb. 1, 2025

ABSTRACT The sediments in mangrove forests play an important role the global carbon cycle due to high inputs of organic matter (OM) and low decomposition rates, making them highly efficient at sequestering carbon. balance between OM sequestration these systems is influenced by a complex interplay environmental factors. However, there large amount uncertainty surrounding rates from forests, particularly regional scales. We used standardized assays labile recalcitrant substrate 30 estuaries, spanning gradient human land use intensity, identify dominant drivers temperate forests. Our results reveal that, while strongly driven eutrophication, primarily increases minimum sediment temperature. Furthermore, we demonstrate that nutrient enrichment use, combination with increased temperature, synergistically accelerates OM, thereby threatening potential ecosystems. This suggests coastal eutrophication can exacerbate effects warming on decomposition, leading heightened vulnerability storage feedbacks local stressors.

Monitoring spatiotemporal changes in global change drivers and their effects on semiarid woodlands and forests - fieldwork protocol

Open Research Europe, Journal Year: 2025, Volume and Issue: 4, P. 270 - 270

Published: March 26, 2025

Training schools play a vital role in COST actions, particularly for young researchers, as they provide opportunities to visit international laboratories and learn new methodologies. In May 2024, CLEANFOREST organized its first training school, Monitoring Spatiotemporal Changes Global Change Drivers Their Effects on Semiarid Woodlands Forests, held at the Faculty of Science Universidade de Lisboa. The school included field trip designed explore global change drivers their impacts semiarid woodlands forests. Participants engaged hands-on activities understand how forest ecosystems interact with key factors such air quality climate change. They were introduced various monitoring techniques parameters assessing health, including ecosystem fluxes, tree physiology, mortality, regeneration. Additionally, participants examined plant biodiversity functional ecology, focusing lichens connection quality, soil physico-chemical properties. applied these methodologies real-world scenarios, conducting measurements (forest structure assessment, lichen diversity sampling, shrub herbaceous estimation, deadwood measurement analysis) different grazing management settings assess effects growth, biodiversity, After practical experience using experiences, divided into groups analyze discuss collected data together trainers. Key findings summarized presentations, main take home messages suggestions further questions be explored related attributes monitor. This paper presents protocol used Companhia das Lezírias, where simplified versions established sampling components employed. provides valuable reference replicating similar studies, ensuring consistency future activities.
