Controls on methane emissions from Alnus glutinosa saplings

New Phytologist, 2013
Summary Recent studies have confirmed significant tree‐mediated methane emissions in wetlands; however, conditions and processes controlling such emissions are unclear. Here we identify factors that control the emission of methane from Alnus glutinosa.

Nutritional effects on the expression of cryptic pigmentation in freshwater isopods

Oikos, Volume 2026, Issue 2, February 2026.
Cryptic pigmentation is a key phenotypic adaptation that helps many benthic invertebrates evade visual predators. However, little is known about whether and how the expression of pigmentation phenotypes that match the habitat background is influenced by the availability of nutritional resources.

Regularities and patterns in the spring phenology of some boreal trees

Silva Fennica, 1999
Phenological time series of flowering and bud burst of Populus tremula (L.) and Betula sp., and the flowering of Pinus sylvestris (L.), Alnus glutinosa (L.) and Alnus incana (L.) were constructed from data collected in Finland during the period 1896–

Study of natural hybridization between Alnus incana (L.) Moench. and Alnus glutinosa (L.) Gaertn.

Journal of Forest Science, 2007
Variation of metric and qualitative characteristics of A. incana (L.) Moench. and A. glutinosa (L.) Gaertn. has been studied in 10 natural populations in West Siberia, Russia and the Czech Republic in connection with the problem of natural hybridization.

Seltene Flavonoid-Aglykone im lipophilen Exkret von Alnus glutinosa / Rare Flavonoid-aglycones in the Lipophil Excretion of Alnus glutinosa

Zeitschrift für Naturforschung B, 1971
The terpenoid excretion on buds of Alnus glutinosa is shown to contain free flavonoid aglycones. These are pectolinarigenine, centaureidin, the 3,6-dimethylether, 6,4′-dimethylether and 3,6,4′-trimethylether of 6-hydroxykaempferol and isorhamnetin.

Comparative phylogenies and host specialization in the alder ectomycorrhizal fungi Alnicola, Alpova and Lactarius (Basidiomycota) in Europe

BMC Evolutionary Biology, 2011
Background Mycorrhizal fungi form intimate associations with their host plants that constitute their carbon resource and habitat. Alnus spp. (Betulaceae) are known to host an exceptional species-poor and specialized ectomycorrhizal (ECM) fungal community

Influence of the tree species on soil parameters and carbon sequestration in silvopastoral systems, Molinopampa district, Amazonas region, Peru

Trees, Forests and People
Silvopastoral systems (SPS's) represent a sustainable alternative to extensive or intensive cattle ranching, which has contributed to soil degradation and deforestation in the Peruvian Amazon. This research was carried out in Molinopampa, Amazonas, Peru,
