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 ...

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.

Defoliation Management and Nitrogen Fertilization Effects on Productivity and Nutritive Value of Aruana Grass Under Irrigated Conditions

Grasses
Nitrogen fertilization is widely recognized as a key factor influencing tropical grass productivity; however, its effectiveness may vary according to pasture developmental stage and management practices.

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 ...

Environmental Stress Effects on Vigor, Mortality, and Growth in Northern Hardwood Forests Along a Pollution-Climate Gradient [PDF]

, 1998
Concern exists over the effects of interacting environmental stresses on the ecological integrity of temperate forests. Coincidence of sensitivity to drought, increasing occurrence of defoliation, and elevated pollutant deposition has produced ...

Influence of frequency and intensity of defoliation on production and morphological development of Panicum maximum Jacq. cv. Sabi

, 1974
Severe defoliation (2cm height) at fortnightly intervals was extremely detrimental to foliage and root dry matter production. High intensity of defoliation appeared to be more detrimental than high frequency.

Utilising leaf number as an indicator for defoliation to restrict stem growth in rhodes grass (Chloris gayana) cv. Callide [PDF]

, 2009
A plot experiment examined the yield response of a nitrogen-fertilised rhodes grass (Chloris gayana) sward to defoliation using the production of a set number of leaves after the last defoliation as the indication for defoliation harvesting. Two factors,

The effect of defoliation on Portulacaria afra.

, 1980
Defoliation is essential in order to increase the production potential of Portulacaria afra. Results indicate that defoliation intensity should range between 25% and 50% and that the season of defoliation is particularly important in maintaining the high
