Aspects of hybrid larch (Larix X eurolepis Henry) as a potential tree species in southern Swedish forestry [PDF]

open access: yes, 2003
The interest in growing hybrid larch (Larix × eurolepis Henry) in southern Sweden has increased in recent decades, one of its assumed advantages being high volume growth.

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

open access: yesAgricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Identifizierung von Haplotypen bei Pityogenes chalcographus (Col., Scolytidae) durch SSCP [PDF]

open access: yes, 2008
Pityogenes chalcographus is a widely distributed spruce pest in Eurasia (KNIZEK et al. 2005). In 70ies, E. Führer studied the intraspecific variation of this spruce bark beetle and detected race differentiation among European populations based on ...

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Responses of ectomycorrhizal fungi to changes in carbon and nutrient availability [PDF]

open access: yes, 2001
Ectomycorrhizal (ECM) fungi may receive 20% of the total C fixed by their host plants and are essential components of host nutrient acquisition. As a consequence of the vast physiological diversity that exists among ECM fungi, changes in community ...

A male-produced aggregation-sex pheromone of the beetle Arhopalus rusticus (Coleoptera: Cerambycidae, Spondylinae) may be useful in managing this invasive species. [PDF]

open access: yes, 2019
The longhorned beetle Arhopalus rusticus (Coleoptera: Cerambycidae, Spondylinae) is a common species in conifer forests of the Northern Hemisphere, but with global trade, it has invaded and become established in New Zealand, Australia, and South America.

Variable species establishment in response to microhabitat indicates different likelihoods of climate‐driven range shifts

open access: yesEcography, EarlyView.
Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically ...
