MULTI-PURPOSE CHESTNUT CLUSTERS DETECTION USING DEEP LEARNING: A PRELIMINARY APPROACH [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
In the early 1980′s, the European chestnut tree (Castanea sativa, Mill.) assumed an important role in the Portuguese economy. Currently, the Trás-os-Montes region (Northeast of Portugal) concentrates the highest chestnuts production in Portugal ...

The immunity paradox: how do plants survive without adaptive immunity?

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Higher plants and mammals exist in similar microbial environments and face similar challenges from microbial pathogens. Both taxonomic groups encode proteins capable of recognizing and triggering responses to pathogens; however, their recognitional capacities differ substantially.

Cyto-molecular characterization of rDNA and chromatin composition in the NOR-associated satellite in Chestnut (Castanea spp.)

Scientific Reports
The American chestnut (Castanea dentata, 2n = 2x = 24), once known as the “King of the Appalachian Forest”, was decimated by chestnut blight during the first half of the twentieth century by an invasive fungus (Cryphonectria parasitica).

Virulence, ligninolytic enzymes and metabolic profile of Cryphonectria parasitica virulent and hypovirulent strains Converted by CHV1 hypovirus

Millenium, 2020
Introduction: Cryphonectria parasitica, the causal agent of chestnut blight, causes necrotic lesions (so-called cankers) on the bark of stems and branches of susceptible host trees. Cryphonectria hypovirus 1 (CHV1) infects C.

Temperature Alters Specificity in a Host–Parasite Interaction

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The Red Queen Hypothesis predicts that host–parasite coevolution maintains genetic variation through strong genetic specificity, but this specificity may be sensitive to environmental conditions. Using Meloidogyne arenaria and its parasite Pasteuria penetrans, we tested host–parasite interactions across three temperatures and found specificity at two ...

Are the ecological and human dimensions of a national park reconcilable? Addressing visitors' preferences for conservation programs

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
The human dimension must be considered in conservation actions. This article presents a discrete choice experiment that analyses the preferences of visitors for the conservation programs being developed in a National Park. The experiment allows identifying certain conflicts between the ecological and social dimensions, and the conclusion is that there ...

Herbaceous Plants in Forest Ecosystems: One Hundred Fundamental and Applied Questions

Journal of Vegetation Science, Volume 37, Issue 4, July/August 2026.
ABSTRACT Aims Herbaceous plants (herbs) found in the understory of forests contribute substantially to the biodiversity of these ecosystems, as well as being important socio‐culturally, economically, and for advancing ecological theory. However, the ecology of herbs is less well understood compared with woody plants, despite evidence that herbs are ...

Soil Pathobiome in Agroecosystems and Forests

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
This review synthesises current knowledge on the soil pathobiome across agroecosystems, horticulture, and forests, highlighting how climate change and intensive management disrupt microbial communities and promote pathogen accumulation. It emphasises soil health as a key component of the One Health framework, linking ecosystem, plant, animal, and human
