Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

open access: yesNew Phytologist, Volume 249, Issue 6, Page 3060-3071, March 2026.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Estimating costs of ecological restoration across degradation scenarios in South Brazilian grasslands

open access: yesRestoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Grassland ecosystems are among the most threatened worldwide, and the Campos Sulinos—a region of subtropical grasslands in southern Brazil—experiences degradation driven by multiple factors. This study provides initial cost estimates for different restoration approaches, offering guidance for technical and budgetary planning ...

Reactivity of a blast furnace slag in latosols [PDF]

open access: yesAfrican Journal of Agricultural Research, 2015
Two experiments were conducted to study reactivity for a blast furnace slag, both developed in a greenhouse, in pots planted with Brachiaria brizantha. A 3 x 4 + 3 factorial was used with four replications, with three slag doses corresponding to 0.6, 1.2 and 2.4 g dm-3 for the clay soil and 2.2, 4.4 and 8.8 g dm-3 for the medium texture soil, four ...

Effect of Pyrolysis Temperature on Phosphorus Release From Fish Scale Biochar in Wheat Crop

open access: yesChemical Engineering &Technology, Volume 49, Issue 2, February 2026.
The results demonstrate that fish scale–derived biochars are effective phosphorus sources with controlled release behavior. Increasing the pyrolysis temperature, particularly to 600°C, enhanced phosphorus availability and promoted diffusion‐controlled release kinetics.

Resistance mechanisms in collard green genotypes to Plutella xylostella: role of physical and morphological traits

open access: yesPest Management Science, Volume 82, Issue 2, Page 1974-1984, February 2026.
Resistance to Plutella xylostella in collard greens is mediated by antixenosis and antibiosis, associated with traits such as leaf wax, hardness, and color. Genotypes showed strong resistance potential, supporting their use in breeding and integrated pest management strategies. Abstract BACKGROUND The diamondback moth, Plutella xylostella (Lepidoptera:

Fiber composition of 190 novel energy cane genotypes and their potential for biorefinery applications

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 253-267, January/February 2026.
Abstract Energy cane has emerged as a promising feedstock for biorefineries due to its high fiber yield and potential for diversified bioproducts. This study evaluated the fiber composition of 190 energy cane genotypes and assessed their theoretical potential for producing second‐generation (2G) ethanol, polyethylene, and xylitol.

Genome‐wide association study and pathway analysis to dissect the genetic control of stay‐green in a Brazilian panel of tropical maize inbred lines

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract The stay‐green trait enables plants to sustain photosynthesis under severe biotic and abiotic stresses and is positively correlated with grain yield in maize (Zea mays L). Despite its importance, information on the inheritance and genetic basis of stay‐green in tropical maize remains limited. This study used genome‐wide association study (GWAS)
