Soil microorganisms play a pivotal role in the biogeochemical cycle and serve as crucial indicators of ecological restoration terrestrial ecosystems. The soil microbial community is regarded participant environmental processes, offering both positive negative feedback to diverse media within ecosystem. This can potential indicator monitoring processes. Consequently, an increasing number scholars are directing their research towards field ecology ecosystems fragile areas, with aim elucidating intricate interactions between microbes vegetation. However, implementation microbiome remains experimental stage due interference extreme events complexity governance measures. comprehensive evaluation existing imperative. review aims address crises currently experienced by provide overview specific practices context restoration.

Leaf Area Index Inversion of Spartina alterniflora Using UAV Hyperspectral Data Based on Multiple Optimized Machine Learning Algorithms

Remote Sensing, Год журнала: 2023, Номер 15(18), С. 4465 - 4465

Опубликована: Сен. 11, 2023

The leaf area index (LAI) is an essential biophysical parameter for describing the vegetation canopy structure and predicting its growth productivity. Using unmanned aerial vehicle (UAV) hyperspectral imagery to accurately estimate LAI of great significance Spartina alterniflora (S. alterniflora) status monitoring. In this study, UAV S. during flourishing period were acquired. data preprocessed with Savitzky–Golay (SG) smoothing, first derivative (FD) second (SD) spectral transformations then carried out. Then, using band combination (BCI) method, characteristic bands related extracted from image obtained UAV, indices (SIs) constructed through bands. Finally, three machine learning (ML) regression methods—optimized support vector (OSVR), optimized random forest (ORFR), extreme gradient boosting (OXGBoostR)—were used establish estimation models. results showed following: (1) ML methods predicted LAI, optimal model was provided by ORFR R2 0.85, RMSE 0.19, RPD 4.33; (2) FD SIs improved accuracy, value improving 41.7%; (3) combinations screened BCI method mainly concentrated in red near-infrared bands; (4) higher distributed on seaward side study area, while lower located at junction between tidal flat. This serves as both theoretical technological research a solid foundation use remote sensing technologies supervisory control alterniflora.

Changes in sediment greenhouse gases production dynamics in an estuarine wetland following invasion by Spartina alterniflora

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Invasive Spartina alterniflora ( S. ) has significant impacts on sediment biogeochemical cycling in the tidal wetlands of estuaries and coasts. However, impact exotic invasion greenhouse gases (GHGs) production dynamics sediments remain limited. Here, we investigated physicochemical properties, GHGs rates, microbial gene abundances a native Cyperus malacensis habitat three invasive habitats (6-, 10-, 14-year) Minjiang River Estuary, China. The methane (CH 4 ), carbon dioxide (CO 2 nitrous oxide (N O) rates varied both spatially seasonally, while (bacterial fungal abundances) organic matter (TOC TN) only spatially. were also characterized by higher values surface (0–10 cm) compared to subsurface (10–20 seasonal variations with summer than winter. can significantly increase CH CO matter, p < 0.05). Temperature, most dominating factor controlling spatio-temporal rates. Overall, our findings highlighted role regulating coastal wetland provided fundamental data for estimating emissions sequestration complex wetlands.

Geographical factor dominates spatial patterns of potential nitrate reduction rates in coastal wetland sediments in Fujian Province, China

Frontiers in Earth Science, Год журнала: 2024, Номер 12

Опубликована: Июль 16, 2024

Nitrate (NO 3 − ) reduction is a key process governing the nitrogen (N) dynamics of coastal wetland sediments. Although effects environmental factors on NO mechanism in sediments have been examined various studies, spatial variation potential processes and driving geographical these not widely examined. Here, we conducted research surface sediment samples from four different vegetation types at six sites across two regions. We characterized rates (including denitrification (DF), anammox (ANA), dissimilatory nitrate to ammonium (DNRA)) using 15 N tracer method. Additionally, assessed abundances functional genes, microbial community structure high-throughput sequencing, metagenomic sequencing. In sites, contribution ranges DF, ANA, DNRA were 38.43%–55.69%, 31.33%–45.65%, 5.26%–17.11%, respectively, was mainly driven by removal via gaseous (DF+ANA). Significant differences observed bacterial fungal communities, suggesting that distance has major effect structure. Environmental Functional gene significantly related processes, physicochemical properties had stronger than abundances. Factors showing significant regions main drivers processes. Overall, our study showed substrates rather abundance genes indicators activities wetlands.

The invasive species Spartina alterniflora has significantly disrupted the ecological stability of coastal wetland ecosystems. Consequently, its control become an important aspect conservation. When controlling S. alterniflora, it is imperative to assess impacts methods. In this study, effects different methods, i.e. "mowing + flooding" (MF) and plowing" (MP), on soil carbon nitrogen contents in wetlands were investigated Yellow River Delta, China. results showed that organic carbon, inorganic total MF area within 2 years after treatment 2.03–3.93 g/kg, 13.74–16.06 0.24–0.47 respectively, which 36.33 %-199 %, 2.91 %-36.71 % 115.42 %-212.09 higher than those CK area, respectively.
