bioRxiv, 2019 Aim Background tree mortality is a complex demographic process that affects forest structure and long-term dynamics. We aimed to test how drought intensity interacts with interspecific and intraspecific competition (or facilitation) in shaping individual

PLANTS, PEOPLE, PLANET, EarlyView.As climate change alters seasonal patterns, temperate tree populations face a growing risk of phenological mismatch, where seed dispersal and germination no longer align with favourable conditions for survival. This study predicted how warming by the end of the century will affect seed dormancy breaking and germination in populations of three UK tree ...

PLANTS, PEOPLE, PLANET, EarlyView.As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Some surface properties of thermally modified scots pine after artificial weathering
Maderas: Ciencia y Tecnología, 2014 In this study, it was aimed to investigate some surface characteristics such as surface roughness, color, and glossiness of Scots pine (Pinus sylvestris) wood specimens after 500 hours artificial weathering exposure.

Microbial succession on decomposing root litter in a drought-prone Scots pine forest
The ISME Journal, 2019 Decomposition is a major flux of the carbon cycle in forest soils and understanding the involved processes is a key for budgeting carbon turnover. Decomposition is constrained by the presence of biological agents such as microorganisms and the underlying

Remote Sensing in Ecology and Conservation, EarlyView.We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Boron retranslocation in Scots pine and Norway spruce [PDF]
Tree Physiology, 2004 We previously traced 10B-enriched boric acid from shoots to roots to demonstrate the translocation of boron (B) in Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) seedlings. To gain a more detailed understanding of B translocation, we sought: (1) to demonstrate B retranslocation directly, by showing that foliar-applied 10B ...

Forest Ecology and Management, 2019 Higher temperatures and extreme drought events are promoting insect-driven tree mortality. However, there is great uncertainty about the impact of extreme climatic variations on the susceptibility to infestation, as this depends on the suitability of ...

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects
Wildlife Biology, EarlyView.Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)
