Abstract Black alder ( Alnus glutinosa [L.] Gaertn.) is an important component of riparian and wetland ecosystems in Europe. However, data on the growth this significant broadleaved tree species very limited. Presently, black currently suffers from pathogen Phytophthora particularly threatened by climate change. The objective study was to focus impact climatic variables (precipitation, temperat...

Abstract Tree allometry is a plastic feature, and scaling parameters can vary considerably depending on phylogeny, life strategies, growth conditions ontogeny. We hypothesized that in multi-layered forests growing rich sites driven by stand dynamics without stand-replacing disturbances, light primary driver of allometric relationships the morphological plasticity tree species closely associated...

The recent Landscape Plan of Tuscany Region pays particular attention towards the floodplain woods, for their conservation concern, landscape, and historical importance. forest vegetation is defined as natural semi-natural wood located close to rivers submerged only during exceptional flooding. We gathered 180 both published unpublished relevés coming from carried out in where Alnus glutinosa ,...

Largely consistent with general predictions and earlier empirical studies, it appears that post-Little Ice Age climate warming has started to affect large-scale biogeographic patterns in northern Sweden. Long-term monitoring subalpine adjacent regions reveals sparse spread of broadleaved thermophilic tree species. Saplings Quercus robur, Ulmus glabra, Acer platanoides, Alnus glutinosa Betula pe...

In March 2022, sunken cankers were observed on the stem and branches of young mature Alnus glutinosa trees in central Portugal (Canelas, 40°42’17’’N; 8°33’59’’W). Cankers characterised by necrotic lesions outer inner bark that progressively girdled circumference causing extensive canopy dieback (Figure 1). The incidence disease was estimated at 70% (linear plot 50 m long). To isolate causal age...

Black alder (Alnus glutinosa) forests are in severe decline across their area of distribution due to a disease caused by the soil-borne pathogenic Phytophthora alni species complex (class Oomycetes), “alder Phytopththora”. Mapping different types damages is challenging high density ecosystems which spectral variability canopy heterogeneity. Data obtained unmanned aerial vehicles (UAVs) may be p...

Gln synthetase (GS) is the key enzyme of primary ammonia assimilation in nitrogen-fixing root nodules of legumes and actinorhizal (Frankia-nodulated) plants. In root nodules of Datisca glomerata (Datiscaceae), transcripts hybridizing to a conserved coding region of the abundant nodule isoform, DgGS1-1, are abundant in uninfected nodule cortical tissue, but expression was not detectable in the i...
