Distinct foliar fungal communities in Pinus contorta across native and introduced ranges: evidence for context dependency of pathogen release

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 1, 2025

Abstract Inter-continental study systems are crucial for testing ecological hypotheses, such as the widely cited Enemy Release Hypothesis (ERH), which seeks to explain superior performance of plant species when they introduced new regions. Pinus contorta (lodgepole pine), native North America, has been extensively Europe and Southern Hemisphere, making it an ideal tree studying invasion hypotheses from a biogeographical perspective. We compared foliar fungal communities, especially pathogens, P. across two native–introduced region pairs (NIRPs): northern NIRP (from Canada Sweden) southern USA Patagonia), while also examining differences between source plantations fronts within Patagonia. underwent significant community shifts experienced pathogen release during its large-scale introduction America Sweden The richness relative abundance changes were more pronounced pair, where no closely related present in In Sweden, presence phylogenetically sylvestris associated local appears play role influencing communities with .

Integrating both phylogenetic perspectives, our suggests priority effects fungi appear be dominant assembly process is done similar community; whereas, distant communities.

Species‐Specific Root Distribution and Leaf Iso/Anisohydric Tendencies Shape Transpiration Patterns Across Heterogeneous Karst Habitats

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 10, 2024

The driving forces of transpiration are not only atmospheric evaporation but also root zone water supply and stomatal regulation among species. However, the biophysiological drivers remain incompletely understood in heterogeneous karst habitats. This study investigated commonly coexisting tree species Mallotus philippensis Celtis biondii two typical habitats: rock-dominated (RD) habitat control soil-dominated (SD) habitat. Over 2 years, soil moisture, transpiration, distribution, leaf potential were measured. results showed that moisture RD was significantly lower than SD Transpiration patterns differed between habitats, with species-specific distinctions driven by traits. M. small hydroscape areas its system mainly distributed both isohydric behaviour density drove to reduce response deficiency. Conversely, C. had large roots capable penetrating bedrock. It transpired higher relying on ample accessible through anisohydric having a more robust bedrock zones Our highlights critical role accessibility iso/anisohydric tendencies transpiration.

Optimization of a Groundwater Pollution Monitoring Well Network Using a Backpropagation Neural Network-Based Model

Water, Journal Year: 2024, Volume and Issue: 16(20), P. 2965 - 2965

Published: Oct. 17, 2024

Selecting representative groundwater monitoring wells in polluted areas is crucial to comprehensively assess pollution, thereby ensuring effective remediation. However, numerous factors can affect the effectiveness of well network optimizations. A local sensitivity analysis method was used this study analyze hydrogeological parameters a simulation solute transport model. The results showed strong effect longitudinal dispersion and transverse on output model, good fit between backpropagation neural (BPNN)-based alternative model’s those obtained using accurately reflecting input relationship optimized layout scheme consisted four wells, namely no. 7, 16, 23, 24. These resulted fluoride pollution rate 98.44%, which substantially higher than that random scheme. In addition, statistical Monte Carlo highlighted continuous high levels second third sources their downstream groundwater. Therefore, more attention should be devoted these ensure remediation area.

Robinia pseudoacacia Quickly Adjusts Its Water Uptake after Rainfall in Seasonally Dry Regions

Forests, Journal Year: 2024, Volume and Issue: 15(11), P. 1854 - 1854

Published: Oct. 23, 2024

Precipitation is a key factor affecting plant growth and development in seasonally arid regions. However, most of the traditional hydrological methods mainly select typically sunny days for sampling, immediate water absorption strategy plants during after rainfall still unclear. This study used stable hydrogen oxygen isotope technology to soil moisture rates Robinia pseudoacacia content at different layers sampling times (0, 6, 12, 18 24 h) rainfall. The results showed that shallow layer decreased, while deep increased over time R. utilized from 0–20 20–40 cm 6 h rainfall, which accounted 36.52% 22.25% respectively. At h, 40–60, 60–80 80–100 contributed 25.25%, 18.44% 24.45% content, retained more within rain fell, retention ratio medium–shallow (0–60 cm) 48.4%, retaining 14–20 h. 12 cm), runoff groundwater constituted 37.1%, 14.4% 15.7% precipitation, respectively, (60–100 32.8%. In summary, tends use large amount regions when precipitation supplements surface it utilizes infiltrates recharges layer. Since sensitive can quickly adjust its depth range short-term period absorb as much possible.
