Adjacent Forests Enhance Spontaneous Revegetation and Phylogenetic Similarity on Mountainous Roadside Slopes: Implications for Ecological Restoration and Forest Edge Management

Ecology and Evolution, Volume 16, Issue 3, March 2026.
The native‐dominated vegetation on roadside slopes primarily originates from adjacent forests, with long‐distance dispersal traits enhancing spontaneous colonization in these disturbed environments. The species composition and phylogenetic similarity between slope and forest communities are significantly influenced by the adjacent forests (species ...

A Clinical Study of Japanese Cedar (Cryptomeria japonica) Pollen-Induced Asthma

Allergology International, 2008
Background: Grass and birch pollens are known to induce asthma. However there are few reports about other pollen-induced asthma. Japanese cedar is the most common allergen in rhinitis in Japan but is controversial on whether it can provoke asthma ...

Influence of Hydrothermal Treatment on Hemicellulose Structure in Cryptomeria japonica

BioResources, 2023
The influence of hydrothermal treatment (HTT) on the hemicellulose, i.e. glucomannan/galactoglucomannan (GM/GGM) and arabinoglucurono-xylan (AGX) in Japanese cedar was examined using mild temperatures (95 °C and 120 °C) for its kiln drying.

Hypersensitivity to Japanese Cedar (Cryptomeria japonica) Pollen in Dogs.

Journal of Veterinary Medical Science, 1995
Four of 51 dogs with chronic dermatitis were made to react to crude Japanese cedar (Cryptomeria japonica, CJ) pollen allergen by the intradermal skin test (IDST). These four dogs had specific IgE to CJ as determined by Prausnitz-Küstner test. In the provocation test, nasal discharge increased 5 to 20 min after introduction of the crude CJ pollen ...
