“…Because Na toxicity induced by salt stress may inhibit plant nutrient uptake. As reported by recent studies, several mangrove tree species can adapt to N limitation caused by salt stress by improving NRE [10,11]. However, in contrast to our expectation, neither leaf chemistry nor NuRE differs significantly between the two contrasting habitats (Figs.…”

“…In contrast, ionic stress often causes unbalanced nutrient uptake because essential mineral nutrients such as NH 4 + and K + are replaced by Na + in the rhizosphere zone [9]. Recent studies have shown that higher nutrient resorption efficiency is an adaptive strategy for several mangrove tree species to meet its nutrient requirement when facing salinity-induced nutrient limitation [10,11]. In contrast to coastal salinization, soil salinity is a common phenomenon in arid environments, as desert soils are often saline due to the intense evaporation, especially within the inland river basin where the water table is relatively high [1,12].…”

Background Soil salinity is a major abiotic constraint to plant growth and development in the arid and semi-arid regions of the world. However, the influence of soil salinity on the process of nutrient resorption is not well known. We measured the pools of both mature and senesced leaf nitrogen (N), phosphorus (P), potassium (K), and sodium (Na) of desert plants from two types of habitats with contrasting degrees of soil salinity in a hyper-arid environment of northwest China. Results N, P, K revealed strict resorption, whereas Na accumulated in senesced leaves. The resorption efficiencies of N, P, and K were positively correlated with each other but not with Na accumulation. The degree of leaf succulence drives both intra-and interspecific variation in leaf Na concentration rather than soil salinity. Both community- and species-level leaf nutrient resorption efficiencies (N, P, K) did not differ between the different habitats, suggesting that soil salinity played a weak role in influencing foliar nutrients resorption. Conclusions Our results suggest that plants in hyper-arid saline environments exhibit strict salt ion regulation strategies to cope with drought and ion toxicity and meanwhile ensure the process of nutrient resorption is not affected by salinity.

“…Under the tropical monsoon climate, the rainy season usually brings a large amount of rainfall that affects the saline environment of mangrove forests (Canini et al, 2013;Krumme et al, 2012;Nasrin et al, 2019;Taillardat et al, 2020). At the same site used in this study, Trat of Thailand, Komiyama et al (2019Komiyama et al ( , 2020 found that the rainfall in the rainy season (May to October) contributed more than 80% of the annual precipitation and that the monthly precipitation correlated with the salinity of the inundating water in the mangrove forest during 2016 and 2017.…”

“…Mangrove forests under the monsoon climate are affected by high precipitation in the rainy season. As a result, soil water salinity in the mangrove forests showed seasonal variation, and the salinity levels decrease during the rainy season due to increasing rainfall, as reported in mangroves in Bangladesh (Nasrin et al, 2019), the Philippines (Canini et al, 2013), and Panama (Starczak et al, 2011). In a tropical monsoon mangrove forest in Trat Province, eastern Thailand, Komiyama et al (2019Komiyama et al ( , 2020 reported that the seasonal variation in soil salinity was influenced by the infiltration of inundating water from the river.…”

Mangrove forests are said to be highly productive ecosystems but it is unclear how they maintain high productivity under the fluctuation of saline environment in the tropical monsoon region. A study of phenological aspects linked with the growth of mangrove trees may be a supportive evidence for this. Here, we studied the seasonal variation in leaf phenology and trunk growth of Avicennia alba trees in a tropical monsoon mangrove forest which has clear rainy and dry seasons at Trat Province, eastern Thailand. For the leaf phenology, the number of new and lost leaves was counted by using demographic techniques, and the monthly rates of leaf emergence and loss were calculated from 45 sample shoots from June 2019 to May 2020. In this period, trunk basal-area increments were also recorded monthly by using dendrometer bands. The rate of leaf emergence showed a remarkable seasonal pattern that was high during the rainy season and low during the dry season. The monthly rate of leaf emergence and trunk growth showed a positive relationship, indicating that both the leaf and trunk growth of A. alba responded to the changing water salinity in the soil. However, the leaf loss rate fluctuated throughout the study period. It was considered that the cambial activity of trunk growth associated with new leaf formation stimulates tree growth under the low saline environment during the rainy season in the tropics. We discussed a growth strategy that will benefit mangrove trees growing in the intertidal areas under fluctuated saline environment.

“…Toprak elektriksel iletkenliği ile olan ilişkisi ise Nasrin ve arkadaşları tarafından yapılan çalışma ile uygunluk göstermektedir. Nasrin ve arkadaşları topraktaki Na konsantrasyonunun azot ve fosfor rezorbsiyonuyla pozitif ilişkili olduğunu bulmuşlardır [77]. Yine mangrov ormanlarında yapılan çalışmalarda, P rezorbsiyonunun tuzlulukla ilişkisinin daha yüksek olduğu tespit edilmiştir [78].…”

In this study, leaf N and P resorption levels of invasive Ailanthus altissima (Mill.) Swingle species were investigated. For this goal, leaf and soil samples were collected during the vegetation period. Thus, it was aimed to determine the amount of N and P elements from the leaves and their relationships with some soil properties. Forests in the Hendek district of Sakarya province which are affected by disturbance and species is gradually spread have been selected as the study area. Leaf and soil samples were collected every month during the vegetation period. The green and senescence periods of the species were determined by using N and P analyzes in the leaf samples taken and the resorption amounts were calculated. In addition, N and P contents, pH and electrical conductivity values of soil samples were measured and their relationships with resorption levels were explained. According to the findings, the N resorption ability of the species was found to be high and P resorption ability was close to the limit values. In addition, it was found that different soil properties (nutrient content, pH and electrical conductivity) did not adversely affect N and P resorption levels. As a result, A. altissima can be developed in areas with low nutrient content, different pH and electrical conductivity values, and so species can be used in plantation studies. Beside the abundance of litter with high nutrient content also enables the soil to enrich in N and P.
