Pinus massoniana, an important timber, producing, and silvicultural species in southern China, exhibits high adaptability wide distribution. This study utilizes the Maximum Entropy Model (MaxEnt), a distribution model based on theory of maximum entropy, to forecast potential suitable areas P. massoniana China under four climate change scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5) for both present future (2080) conditions. The research integrates analyzes effects various environmental factors, including topography, soil, population, massoniana. Additionally, geographical detector is employed assess interaction between different factors their contribution variation suitability zones.The findings indicate that MaxEnt accurately predicts with AUC values exceeding 0.94. Precipitation driest month (BIO14), population density (POP), annual precipitation (BIO12) emerge as main influencing current Notably, BIO14 has greatest impact species' (43%), followed by POP (32.7%). Furthermore, lower correspond higher probabilities pine distribution, while correlate increased probabilities. primarily concentrated climatic conditions, encompassing total survival zone 25.24 × 105 km2, accounting 26.29% China's area. Among regions, Guangxi largest area survival, reaching 28.9 104 implying characteristics are conducive massoniana's survival. Under scenarios, overall pattern range remains similar one, increasing trend SSP3-7.0 emissions scenario shows most significant increase area, totaling 4.71 suggesting this particular more favorable provides valuable scientific insights management, conservation, rational site selection

Assessment of 40-year Al Deposition in some Exotic Conifer Species in the Urban Air of Düzce, Türkiye

Water Air & Soil Pollution, Год журнала: 2025, Номер 236(2)

Опубликована: Янв. 3, 2025

Abstract Heavy metal (HM) pollution in urban air, a global dilemma, has increased drastically the last century. Aluminum (Al) is one of HMs and neurotoxic element that can be absorbed into human tissues through digestion, breathing, skin. Al accumulation humans cause diseases even death. Due to risks it poses environmental health, vital track contamination shifts airborne decrease them. In this study, 40-year concentration differences Pseudotsuga menziesii , Cedrus atlantica Picea orientalis Cupressus arizonica Pinus pinaster grown Düzce, Türkiye, fifth most polluted European town, terms direction, tree species, tissue type were assessed. As result, generally varies as outer bark > inner wood. Whole species accumulate significantly, transfer between adjacent cells wood part limited. conclusion, all used biomonitors temporal changes. However, highest concentrations, especially part, observed these chosen suitable phytoremediation studies.

Monitoring groundwater potential dynamics of north-eastern Bengal Basin in Bangladesh using AHP-Machine learning approaches

Ecological Indicators, Год журнала: 2023, Номер 154, С. 110886 - 110886

Groundwater is a vital natural resource that plays critical role in sustaining agriculture, forest ecosystems, industry, and household uses. However, due to anthropogenic factors, groundwater facing alarming declines. Therefore, this study aimed assess the potential zones (PGWZ) north-eastern Bengal Basin of Bangladesh between 1990 2021 using satellite images, public field data pertaining ten environmental parameters. The utilized analytical hierarchy process identify PGWZ evaluated effectiveness machine learning (ML) algorithms (K-nearest neighbors, support vector machine, XGBoost, decision tree, random forest) for classification. findings indicated decline over decades, which was categorized into five distinct based on relative potential. very high decreased from 2.19% 1.3%, 34.57% 28.24%, while there sharp increase poor status (very low, medium zones) same periods. accuracy kappa coefficients ground validation estimated map were 84.34% 79.61%, respectively. According accuracy, precision, recall, f1-score, ML models are reliable predictors PGWZ. RF achieved highest 92.33%, XGBoost an 90.31%. Both demonstrated superior prediction performance normalized leverage factor. attributes alteration changes land use covers, increased surface temperatures, rainfall, soil erosion region three decades. results offer valuable insights decision-makers make informed decisions sustainable responsible management resources.

Phytoremediation and long-term metal uptake monitoring of silver, selenium, antimony, and thallium by black pine (Pinus nigra Arnold)

BioResources, Год журнала: 2024, Номер 19(3), С. 4824 - 4837

Опубликована: Май 31, 2024

The usability of black pine (Pinus nigra Arnold) in both monitoring the changes concentrations silver (Ag), selenium (Se), antimony (Sb), and thallium (Tl), reducing soil or air pollution was investigated. In study, annual rings a Pinus tree, cut 2023 identified as 356 years old, were grouped into 10-year intervals, then these heavy metals throughout process determined by analysing elements. Additionally, relationship elements with other also detected scope study. study results suggested that not suitable bio-monitor for Ag, Se, Sb, Tl air, but it highly species phytoremediation studies aimed at Moreover, relationships studied essential nutrients, such Mg, Ca, P, K, Al, Zn, Ni, Fe, statistically significant very weak; whereas they exhibited positive strong known to be harmful health V, Pb, As.

Nowadays, the applications of nanotechnology are increasing in various fields such as information technology, energy, medical sector, and agriculture. Nanotechnology has proved its ability to solve problems agriculture related industries. Establishing impact nanoparticles on ecosystems become a primary research topic, but studies forest trees quite limited. This study examined effects silver germination parameters oriental beech seeds established their toxic threshold values. Silver were applied at concentrations 200, 400, 600, 800, 1000 mg/L (Fagus orientalis) collected from 10 different populations order identify rate, percentage, seedling height, root collar diameter, plumula length, radicle thickness, length parameters. The results revealed that have negative effect seeds, this is clearly seen rate 20 levels characters starting 60 dose, causing decrease 13% 24% 40% 30% length. Kahramanmaras-Andirin population was found be most affected by nanoparticles, while Bursa-Inegol Ordu-Akkus least affected.

Kastamonu University Journal of Forestry Faculty, Год журнала: 2024, Номер 24(1), С. 81 - 91

Опубликована: Март 28, 2024

Aim of the study: In process global climate change (GCC), migration mechanism needed especially for forest trees must be provided by humans. For this purpose, contrary to previous studies, detailed studies carried out on small areas are needed. Area present study in Kastamonu Regional Directorate Forestry, which performs highest level wood production Türkiye, it was aimed specify actual distribution Abies and their suitable due GCC. Material methods: study, besides existing potential future areas, also were determined using SSP 126, 370, 585 scenarios years 2040, 2070, 2100 at Kastamonu. Main results: The results achieved there showed that, depending change, populations would form an increase general. Research highlights: This species (Abies) seems incapable keeping up with such changes without human intervention. Thus, considering results, is recommended make necessary amendments management plans.
