Bark Thickness Equations for Mixed‐Conifer Forest Type in Klamath and Sierra Nevada Mountains of California

open access: yesInternational Journal of Forestry Research, Volume 2016, Issue 1, 2016., 2016
We studied bark thickness in the mixed‐conifer forest type throughout California. Sampling included eight conifer species and covered latitude and elevation gradients. The thickness of tree bark at 1.37 m correlated with diameter at breast height (DBH) and varied among species.

Analysis of Inheritance and Growth of Curly Birch Progenies from Controlled Hybridisation and Possibilities of their Utilisation for Timber Production in Agricultural Landscape

open access: yesCzech Journal of Genetics and Plant Breeding, 2004
The influence of habit form on progeny growth was studied within the evaluation of the height growth of curly birch hybrid progenies. In all years 1998, 1999 and 2001 statistically significant differences in height were found between progenies in ...

Caatinga Revisited: Ecology and Conservation of an Important Seasonal Dry Forest

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
Besides its extreme climate conditions, the Caatinga (a type of tropical seasonal forest) hosts an impressive faunal and floristic biodiversity. In the last 50 years there has been a considerable increase in the number of studies in the area. Here we aimed to present a review of these studies, focusing on four main fields: vertebrate ecology, plant ...

What Risk Does Phytophthora ramorum Pose to Sitka Spruce (Picea sitchensis) and Other Conifers in Britain?

open access: yesForest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Larch (Larix) and, to a lesser extent, rhododendron (Rhododendron ponticum) have emerged as key drivers of the Phytophthora ramorum epidemic in Britain because of the copious numbers of sporangia that are released from their foliage following infection; the inoculum then initiates stem and foliar infections on nearby broadleaf and conifer ...

The Importance of Within‐Log Sampling Replication in Bark‐ and Wood‐Inhabiting Fungal Metabarcoding Studies

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Despite the widespread use of metabarcoding approaches in wood‐inhabiting fungal studies, there is currently no standardized procedure for sampling deadwood. Our methodological study supports that to gain a representative view of the fungal community composition in early decay‐stage deadwood, bark should be included in fungal surveys and that ...

Surface Damaged by Xylotrechus arvicola Larvae on Vitis vinifera: Relationship With Resistance and Breaking Times

open access: yesAustralian Journal of Grape and Wine Research, Volume 2025, Issue 1, 2025.
Background and Aims: The main wine‐producing areas of the Iberian Peninsula are affected by Xylotrechus arvicola, an insect pest species which causes structural and biomechanical damage in vineyards (Vitis vinifera) due to the ingestion of vascular tissues. Methods and Results: To evaluate the mechanical properties of wood affected by X.

Phenology of Xylotrechus arvicola (Coleoptera: Cerambycidae) Adults in Spanish Vineyards

open access: yesAustralian Journal of Grape and Wine Research, Volume 2025, Issue 1, 2025.
Background and Aims: The longicorn beetle Xylotrechus arvicola (Olivier) (Coleoptera: Cerambycidae) is an important pest in vineyards of the Iberian Peninsula. Previous studies have reported that different varieties of grapevines Vitis vinifera exhibit varying susceptibility to infestation by this species. Methods and Results: Adult X.

Wood nutrients: Underexplored traits with functional and biogeochemical consequences

open access: yesNew Phytologist, Volume 244, Issue 5, Page 1694-1708, December 2024.
Summary Resource storage is a critical component of plant life history. While the storage of nonstructural carbohydrates in wood has been studied extensively, the multiple functions of mineral nutrient storage have received much less attention. Here, we highlight the size of wood nutrient pools, a primary determinant of whole‐plant nutrient use ...
