Soybean induced resistance to Spodoptera eridania herbivory

Pest Management Science, Volume 82, Issue 10, Page 9931-9943, October 2026.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Multifactorial diagnosis of drought‐induced decline in Mediterranean conifer forests

Journal of Ecology, Volume 114, Issue 10, October 2026.
A multi‐proxy approach integrating radial growth, leaf morphology, stable isotopes, elemental composition and soil properties revealed interacting mechanisms underlying drought‐induced dieback in Mediterranean pine populations. Declining trees showed stronger drought impacts on growth, altered stomatal regulation, nutrient imbalances and accelerated ...

STRUCTURE AND PRODUCTIVITY OF TANZANIA GRASS SUBJECTED TO DIFFERENT DEFOLIATION FREQUENCIES

Ciência Animal Brasileira, 2017
The objective of the present study was to evaluate the effect of different frequencies of defoliation at fixed periods on the structural and productive characteristics of Tanzania grass (Panicum maximum) under Am climate conditions in 2014.

Shrub canopies preserve climatic niche disparity among recruit species in Mediterranean drylands

Journal of Ecology, Volume 114, Issue 10, October 2026.
Shrub canopies create microrefuges for recruit diversity. Across 10 Mediterranean shrublands, recruits beneath canopies encompassed a wider range of climatic niches and greater phylogenetic diversity than those in open ground. By hosting diverse climatic strategies, plant canopies may help sustain biodiversity under climate change, offering a ...

Preventing Invasive Non‐Native Species: A Horizon Scanning for the Canary Islands

Diversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim Oceanic islands host exceptional biodiversity and endemism but are highly vulnerable to biological invasions. We aimed to identify non‐native species with high potential to invade the Canary Islands within the next decade and to prioritise them based on their environmental and socioeconomic risks.

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

Forest 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

Optimising Defoliation Frequency and Intensity to Enhance Forage Accumulation in Annual Ryegrass

Grass and Forage Science, Volume 81, Issue 4, October/December 2026.
ABSTRACT To increase grazing efficiency, it is necessary to understand morphogenetic responses and how they drive forage harvest. Our objective was to evaluate defoliation frequency (time between defoliations required for the expansion of 2, 3 and 4 leaves) and intensity (low: maintenance of 50% stubble height; intermediate: maintenance of 25% stubble ...

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

New Phytologist, Volume 252, Issue 1, Page 324-339, October 2026.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.
