“…Second, the regular alternation between flooding and dry periods favours nutrient release from soil organic matter, allowing a rapid uptake by species. These results do not reveal the direct influence of site fertility, since for N and K, for example, there is a negative relation between soil content and mature leaf content, which is in contradiction with results of a study on a Mediterranean Quercus ilex forest [32] These authors attribute higher N and P concentrations in relation to higher soil content to a higher temperature and water availability which enhances microbial activity. In the flooded sites, the water and nutrient availability was improved.…”

“…Our results confirm that there is no direct effect of soil fertility on resorption [1], as already shown for nitrogen uptake. The difference in resorption could be attributed to the fluctuations in water level and consequently to the soil moisture availability which has been stressed as an important determinant of nutrient resorption efficiency by Aerts [1]: thus a higher resorption value was observed at sites with higher water availability [32]. However, the difference in soil humidity between the two types of sites are not very great (humidity around 45-50 %).…”

“…Soil fertility is often considered as a main factor in controlling resorption. However, the relationship between resorption and soil fertility is a controversy with a long history: some studies have shown that resorption may increase with rising nutrient availability [13,27,28,32,39], others that there is a decrease with increase in soil nutrient content [5,11] and in other cases, resorption efficiency is not influenced by soil conditions [1,4,16] suggesting that other parameters can influence resorption. In alluvial forests, regularly flooded sites offer the best conditions for plant nutrition, particularly when the flood waters are nutrientrich and the soils not too reducing to lead to a removal of nitrogen by denitrification, for example [9,20,22,42,43].…”

-This paper focuses on the impact of flood on tree mineral nutrition through measurement of resorption (i.e. transfer of nutrients from leaves to perennial organs). Nutrient (N, P, K, Mg, Ca) concentrations in leaves of three representative species, Fraxinus excelsior L., Ulmus minor Mill. and Clematis vitalba L. were measured before and after abscission on flooded and unflooded hardwood forests of the upper Rhine plain. The nutrient concentrations in the soils, which were measured in the top layer of the study sites, were higher in the flooded sites for P but slightly lower for N and K, and identical at both types of site for Ca and Mg. The summer foliage concentrations were higher for N and P in the flooded areas, and probably related to the flooding process, which contributes to regular nutrient inputs in the flooded forest, causes high fluctuations of water level and increases bioavailability of certain nutrients. Resorption occurred for all nutrients in the three species, and was higher for N, P and K (40-70 %)

As part of an intensive monitoring programme (MON.I.TO, Intensive Monitoring of Forests in Tuscany), a 3-year survey was carried out, which included three tree species (beech, Fagus sylvatica L.; Turkey oak, Quercus cerris L.; holm-oak, Quercus ilex L.) located at six different sites. Leaves were sampled annually and analysed for nutrient concentrations (nitrogen, sulphur, phosphorus, magnesium, calcium, potassium and sodium) and morphological parameters (leaf area, dry weight, leaf mass per area, leaf thickness and leaf density). Results indicated considerable interannual variation of all the parameters. Differences between sampling sites indicated that, of all parameters measured, leaf mass per area could explain best the differences in field performance under conditions of stress. In fact, leaf mass per area was greater in the drier sites or when sea salt deposition occurred. Nevertheless, the variation of leaf mass per area over the 3 years did not reflect the differences in rainfall. Higher leaf mass per area was accompanied by lower concentrations of phosphorus and nitrogen, which could be a dilution effect due to an increase of structural carbon compounds in sclerophyllous leaves, as revealed by the total foliar content of these elements. Leaf mass per area as a measure of sclerophylly reached very high values among mesophile vegetation. Long-range transport of sea salt from coastal areas to mountain areas was mirrored in sodium concentrations of leaves.

“…Leaf RE of mangroves is commonly high and can be as high as ∼95.36% for N and ∼82% for P (Lin et al 2010, Lovelock et al 2004. The response of nutrient resorption to nutrient availability has shown mixed results, including negative (Kobe et al 2005), positive (Sabaté et al 1995) and no response (Lin et al 2010). For example, a meta-analysis based on a global data set of perennial species (9703 observations at 306 sites from 508 publications) showed a negative relationship between nutrient availability and plant resorption efficiency (Kobe et al 2005, Yuan & Chen 2015.…”

Mangrove species maintains constant nutrient resorption efficiency under eutrophic conditions

Mangrove species have developed nutrient conservation mechanisms to adapt to oligotrophic intertidal environments. However, nutrient enrichment occurs worldwide, particularly in estuarine and coastal regions. Mangrove species may change their adaptive strategies if nutrient availability increases substantially. To understand how nutrient resorption (a major nutrient conservation strategy) responds to nutrient enrichment, a common mangrove species in China, Aegiceras corniculatum (black mangrove), was selected, and saplings were cultivated in nutrient-enriched soils. After one year, neither N nor P resorption efficiency showed significant variations with nutrient availability and there was no difference between N and P resorption efficiency. Overall, nutrient resorption efficiency of A. corniculatum remained at ∼40%, lower than the global average levels of evergreen plants (∼50%), indicating incomplete resorption of nutrients. Incomplete resorption was also evidenced by the nutrient concentrations, resorption proficiency and N: P ratio of plant leaves. Collectively, these results indicate that black mangrove can maintain constant nutrient resorption efficiency under eutrophic conditions.
