Spatiotemporal patterns of genetic variation for growth and fertility in Scots pine [PDF]
, 2011 Genetic testing plays an important role in tree breeding. Understanding basic genetic parameters for growth and fertility is a prerequisite for developing a successful breeding strategy to balance between short- and long-term gains.

Using phenology to improve invasive plant detection in fine‐scale hyperspectral drone‐based images
Remote Sensing in Ecology and Conservation, EarlyView.Using drone‐based hyperspectral images of mixed temperate successional forests collected over a growing season, detection algorithms were produced for three invasive species of interest, which are not only invasive in Virginia but also much of the U.S.: Ailanthus altissima (tree of heaven), Elaeagnus umbellata (autumn olive), and Rhamnus davurica ...

Effect of thermal rectification on colors of Eucalyptus Saligna and Pinus caribaea Woods
Maderas: Ciencia y Tecnología, 2012 Eucalyptus saligna and Pinus caribaea var. hondurensis woods underwent a variety of thermal rectification treatments (from 120ºC to 180ºC) to evaluate the effect of heating on their colorimetric properties.

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 ...

XYLOGENESIS OF PINUS HELDREICHII AND PINUS PEUCE IN PIRIN MTS. [PDF]
Bulgarian Journal of Agricultural Science, 2013 Pinus heldreichii and Pinus peuce are tree species characterized by longevity. Previous studies have outlined the potentialfor constructing long tree ring chronologies which may be used for studying the climatic variation in the past. A diffi culty isthe mixed climatic signal with negative effect of summer droughts but also of extremely cold summers ...

Retrospective image analysis for long‐term demography using Google Earth imagery
Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...
