Populus; administrative management; biomass; calcium carbonate; exchangeable calcium; fertilizers; forest ecology; models; nutrient availability; nutrition; pH; trees; Italy
Abstract:
... The cultivation of Populus spp. on acid soils is difficult mainly due to low nutrient availability, limiting the distribution and use of this marketable tree species. In this paper we report the results of two experiments, in which a granulated highly reactive micronized calcium carbonate (CaCO₃) was tested at increasing levels to improve the effect of NPKS fertilization on poplar growth. Twin fie ...

Abstract:
... Populations of large herbivores, including members of the deer family Cervidae, are expanding across and within many regions of the northern hemisphere. Because their browsing on trees can result in economic losses to forestry and strongly affect ecosystems, it is becoming increasingly important to understand how best to mitigate resultant damage. Previous research has highlighted the importance o ...

The microbial C use efficiency (CUE) and N use efficiency (NUE) are critical to elemental cycling in terrestrial ecosystems, which can be calculated by the C:N stoichiometry of soils, microbial biomass, and extracellular enzyme activities. However, little is known about how drought affects m ...

Abstract:
... Long-term sustainability of forest resources is in question given wide-spread use of conventional clear-cut silviculture. In response, variable retention (VR) harvest has been increasingly promoted as a landscape-based approach to enhance sustainability by maintaining biodiversity and other ecosystem functions in managed forests. Although the success of the VR approach depends on post-harvest stan ...

Abstract:
... Aphids can affect the growth or architecture of their host-trees, but rarely challenge their survival. Nonetheless, the woolly poplar aphid, Phloeomyzus passerinii, can kill healthy, mature poplars during outbreaks. Trees fail to open their buds and flush their leaves in the spring following a severe infestation. This insect develops on poplar trunks, where it induces galls which accumulate amino ...

Abstract:
... Stand dynamics in the boreal forest are driven by wildfire, and many think that emulating forest fire patterns during harvesting will adequately preserve biodiversity. We tested this hypothesis by examining saproxylic beetle assemblages from a chronosequence of aspen forest stands originating after wildfire or harvest across several age classes (1–2, 14–15, 28–29years old) as well as from mature ( ...
