Convolutional Neural Network with a Learnable Spatial Activation Function for SAR Image Despeckling and Forest Image Analysis

Remote Sensing, 2021
Synthetic aperture radar (SAR) images are often disturbed by speckle noise, making SAR image interpretation tasks more difficult. Therefore, speckle suppression becomes a pre-processing step.

Arboreal Urban Cooling Is Driven by Leaf Area Index, Leaf Boundary Layer Resistance, and Dry Leaf Mass per Leaf Area: Evidence from a System Dynamics Model

Atmosphere, 2023
Heat waves are becoming more frequent due to climate change. Summer heat waves can be particularly deadly in cities, where temperatures are already inflated by abundant impervious, dark surfaces (i.e., the heat island effect).

Mini review: Application of the somatic embryogenesis technique in conifer species

Forestry Research, 2022
The somatic embryogenesis (SE) process is better suited to large-scale production and automation than other clonal propagation methods such as the rooting of cuttings.

Comparative Repeat Profiling of Two Closely Related Conifers (Larix decidua and Larix kaempferi) Reveals High Genome Similarity With Only Few Fast-Evolving Satellite DNAs

Frontiers in Genetics, 2021
In eukaryotic genomes, cycles of repeat expansion and removal lead to large-scale genomic changes and propel organisms forward in evolution. However, in conifers, active repeat removal is thought to be limited, leading to expansions of their genomes ...

The phenotypic and genetic effects of drought-induced stress on wood specific conductivity and anatomical properties in white spruce seedlings, and relationships with growth and wood density

Frontiers in Plant Science, 2023
Drought frequency and intensity are projected to increase with climate change, thus amplifying stress on forest trees. Resilience to drought implicates physiological traits such as xylem conductivity and wood anatomical traits, which are related to ...

Acrodontium burrowsianum and Pestalotiopsis humicola: Two Previously Unrecorded Fungal Species Isolated from Conifer Leaves in Korea

한국균학회지, 2022
Endophytic fungal strains were isolated from the leaves of two conifer species (Juniperus rigida and Pinus densiflora) in Korea and identified on the basis of their morphological and molecular characteristics.

Still standing: Recent patterns of post-fire conifer refugia in ponderosa pine-dominated forests of the Colorado Front Range.

PLoS ONE, 2020
Forested fire refugia (trees that survive fires) are important disturbance legacies that provide seed sources for post-fire regeneration. Conifer regeneration has been limited following some recent western fires, particularly in ponderosa pine (Pinus ...

Performance and genetic variation in a provenance test of Araucaria cunninghamii

Pesquisa Agropecuária Brasileira, 2021
: The objective of this work was to assess the genetic variability of Araucaria cunninghamii in a provenance test and to estimate the genetic gains in its wood production, based on different selection intensities.
