Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

open access: yesEcography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

open access: yesEcological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

Strong diel variation in the activity of insect taxa sampled by Malaise traps

open access: yesEcological Entomology, EarlyView.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

Sensitivity of Picea abies to butt rot in pure stands and in mixed stands with Pinus sylvestris in southern Sweden

open access: yesSilva Fennica, 2002
Repeatedly sampled data from permanent experimental plots in southern Sweden were used to model butt rot development in Norway spruce growing in pure stands and in mixed stands with Scots pine.

Non-destructive wood density assessment of Scots pine (Pinus sylvestris L.) using Resistograph and Pilodyn

open access: yesPLoS ONE, 2018
We tested two methods for non-destructive assessment of wood density of Scots pine standing trees: one based on penetration depth of a steel pin (Pilodyn) and the other on micro-drilling resistance (Resistograph). As a benchmark we used wood density data

Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure

open access: yesPhysiological Entomology, EarlyView.
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective

Modelling biomass of young and dense Scots pine (Pinus sylvestris L.) dominated mixed forests in northern Sweden

open access: yesSilva Fennica, 2014
Biomass models for the biomass of above-ground tree components of Scots pine ( L.), Norway spruce ( [L.] Karst.) and birch ( Roth and Ehrh.) in young dense Scots pine dominated forest stands in northern Sweden were constructed.

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe

open access: yesPlant Biology, EarlyView.
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Molecular characterisation of Pinus sylvestris (L.) in Ireland at the western limit of the species distribution

open access: yesBMC Ecology and Evolution
Background Scots pine (Pinus sylvestris L.) underwent significant population declines across much of northwest Europe during the mid-to-late Holocene and was thought to have become extirpated in Ireland from about 400 AD. However, most extant populations

Are Scots pine forest edges particularly prone to drought-induced mortality?

open access: yes, 2018
Climate change is expected to exacerbate the frequency of drought-induced tree mortality world-wide. To better predict the associated change of species composition and forest dynamics on various scales and develop adequate adaptation strategies, more ...
