The Role of Environmental Parameters in the Evolution of Holm Oak (Quercus ilex L. subsp. ballota (Desf.) Samp) Decline: Studies in the Iberian Peninsula

open access: yesForest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT The combination of geographical factors (climate, slope, orientation, lithology, water availability, etc.) and the pathogenicity of agents such as the oomycete from the kingdom Straminopile Phytophthora or Pythium species causes the plant disease known as oak decline in the Iberian Peninsula. Leaving aside the presence of the pathogen, the aim

Pear Blister Canker Viroid Isolated from European Pear in Japan.

open access: yesJapanese Journal of Phytopathology, 1997
A viroid was detected from European pears cultivated in Fukushima and Yamagata prefectures, Japan. Nucleotide sequence analysis of each of the Fukushima and Yamagata isolates revealed that they were isolates of pear blister canker viroid (PBCVd) reported in France. The Fukushima isolate consisted of 312 nucleotides, whereas the Yamagata isolate had 313

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1563-1566, September 2026.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...
