“…In case of Zn, recommended foliage content should vary between 14 and 25 µg•g -1 in Q. petraea, and 15-25 µg•g -1 in Q. robur. Similar values have been reported by other authors [30,31], although certain authors reported the content of Zn in the leaves of studied oak species that was beyond these limits [26,27,29].…”

“…Lower values were also reported by other authors: i.e. Kovács et al [26] and Santamaría and Martin [30] reported that average foliar concentration of Mn in Q. robur amounted to 817 and 821 µg•g -1 , respectively. Likewise, studying HMs content in the leaves of Q. robur trees grown across rural areas of Galicia, Aboal et al [29] evidenced that average concentration of Mn was approximately 305 µg•g -1 .…”

“…[26][27][28]). Unlike these findings, Aboal et al [29] and Santamaría and Martin [30] recorded Fe concentration outside the given ranges. In case of Zn, recommended foliage content should vary between 14 and 25 µg•g -1 in Q. petraea, and 15-25 µg•g -1 in Q. robur.…”

Background and Purpose: Due to the ability to uptake and accumulate heavy metals (HM) in their aboveground tissues, trees may be used for phytoremediation purposes, but also as bioindicators of environmental pollution. The aims of the present study were: a) to investigate the content and temporal variation of the studied HMs in different plant organs during the period of intensive leaf falling (September-October), in two species from genus Quercus; b) to evaluate the observed HMs content relative to plausible ranges of element concentration in foliar litter, as recommended by ICP Forests Foliar Co-ordinating Centre (IFFCC). Material and Methods: The contents of zinc (Zn), manganese (Mn), copper (Cu) and iron (Fe) were assessed in the litterfall (i.e. leaves and branches) of Quercus petraea (Matt.) Liebl. and Quercus robur L. grown at two ICP Forests Level II monitoring plots (Fruška Gora and Odžaci, Serbia). Plant material was sampled during September-October 2018 and analyzed by atomic absorption spectrophotometry. Results: Comparing the content of investigated HMs in foliar litter and branches of Q. robur and Q. petraea, notably higher concentrations of Mn and Fe have been observed in the foliage of both species, whereas Zn and Cu concentrations were higher in collected branch material of both of the above-mentioned tree species. The results further showed that, when compared to plausible ranges of element concentrations in foliar litter, given by ICP Forests Foliar Co-ordinating Centre (IFFCC), average concentrations of Fe and Zn in the leaves were within suggested limits, whereas certain concentrations of Mn and Cu exceeded the proposed ranges. Furthermore, the content of the studied HMs in plant material of both Quercus species significantly varied during sampling period. Conclusions: Although it was observed that concentrations of certain HMs were beyond plausible limits recommended by IFFCC, our results were in accordance with the findings of other authors who studied HMs content in Quercus species grown in natural forests. For that reason, these limits should be considered optionally, i.e. in the cases when the results significantly deviate from the suggested values. Moreover, we believe that the observed variation in the HMs content during sampling period is related to the sampling procedure commonly applied at ICP Forests monitoring plots, which is indirectly associated with the capacity of trees to accumulate HMs and their phenological properties.

“…Naturally, the relief as a factor should also be taken into account, because the research area abounds in terrains with bigger or smaller slopes. Some authors relate the relief and especially precipitation amounts to the quantity of the organic cover (Santamaria, Martin, 1998). In our research, the highest amount of the organic matter, as has already been pointed out, was recorded in chromic cambisols (CMx), which can be attributed to higher altitudes at which these soils occur.…”

The experiment was set up in the forest ecosystem with diverse vegetation zones in the area of Istria and the Croatian Littoral. Research included the following systematic soil units: lithic leptosols, rendzic leptosols, rendzic leptosols -eroded, mollic leptosols, chromic cambisol and chromic luvisols. The average quantity of the forest litter in the studied systematic soil units reaches 13.36 t/ha (Tables 1−3). The "wealth" of organic matter in the studied soil units can be presented with the following series: chromic cambisols (CMx) > mollic leptosols (LPm), organogenic, rendzic leptosols (LPk) > lithic leptosols (LPq) > chromic cambisols (CMx) -Terra rossa, chromic luvisols (LVx) > rendzic leptosols (LPk) -eroded. As expected, the lowest value of total nitrogen was found in the lithic leptosols in relation to almost all the other soils, except when compared with chromic cambisol and rendzic leptosols (p < 0.05). The statistically justified higher values of the percentage share of P 2 O 5 in the forest litter were found in chromic luvisols and rendzic leptosols -eroded in relation to the other studied soils. Significantly higher level of copper contamination was inside rendzic leptosols -eroded in relation to the other studied soils. The exception is rendzic leptosols (p < 0.05). A significantly higher zinc content was detected in the lithic leptosols in relation to the other soil units, except for chromic luvisols, while a justifiably higher total lead and cadmium content in the forest litter was observed in chromic luvisols in relation to the other compared soils (p < 0.05).

“…Hence, litterfall production is low in high latitudes where a short growing season limits plant growth, but increases towards equatorial latitudes, where plants are able to grow during the whole year (Albrektson, 1988). At a regional scale, differences in litterfall production may exist between sites due to climate modification by topography (Santamaría and Martín, 1998). This fact is especially important in the Iberian Peninsula, where altitude gradients generate highly diverse environments within small areas.…”
