Alike but still different: coexistence of four raptor species explained by breeding habitat segregation

open access: yesOikos, EarlyView.
Understanding how species competing for similar resources coexist and influence each other has been, and still is, one of the big questions of community ecology. This question has often been tackled by comparing ecological niches of species pairs, although usually more than just two species compete for the same resources.

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

open access: yesOikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Comparative Study Regarding the Chemical Composition and Biological Activity of Pine (Pinus nigra and P. sylvestris) Bark Extracts

open access: yesAntioxidants, 2021
The bark resulted after the industrial processing of wood represents a byproduct of the forestry industry, used in many suboptimal ways, being considered a natural waste.

Climate‐driven intraspecific shifts in seed germination phenology: Consequences for native temperate woodland restoration and regeneration

open access: yesPLANTS, 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 ...

An integral model for natural regeneration of Pinus pinea L. in the Northern Plateau (Spain) = Modelo integral de regeneración natural para Pinus pinea L. en la Meseta Norte (España) [PDF]

open access: yes, 2013
Natural regeneration is an ecological key-process that makes plant persistence possible and, consequently, it constitutes an essential element of sustainable forest management.

The Photosynthetic Characteristics of Pinus Sylvestris var. Mongolica and Pinus Tabulaeformis in Mu Us Sandland

open access: yesShuitu baochi yanjiu, 2011
In the growing season,the daily gas exchange,water use efficiency of Pinus sylvestris var.mongolica and Pinus tabulaeformis in Mu Us sandland were measured with a portable Li-6400 gas analysis system under natural conditions.The results showed that the ...

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

open access: yesPLANTS, 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 ...

Aboveground herbivory elevates belowground rhizosphere volatile organic compound concentrations in ambient and polluted air, independent of volatile sampling methodology

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The effect of air pollution on plants is still underexplored, especially belowground. We used a field facility that released diesel exhaust and ozone at concentrations equivalent to those near a busy road in Reading, UK, to measure belowground gas exchange of Scots pine together with feeding by large pine weevils, a major pest of conifers.

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

open access: yesRemote 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 ...
