Henry Trimen: Under‐appreciated pioneer in the typification of Linnaean plant names?

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract In 1887, Henry Trimen published a paper summarising the contents of the Hermann Herbarium, in what is now the Natural History Museum, London (BM), in terms of the plant names published by Linnaeus. Trimen referred to the Hermann specimens as types of Linnaeus's names.

Response of cereals to intercropping with non‐food crops in tropical and subtropical regions: A meta‐analysis

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping cereals with non‐food intercrops (NFICs) provides a means to enhance cereal productivity while providing additional benefits such as improved soil health or forage production. We conducted a meta‐analysis to investigate the effect of NFICs on cereal yields, cereal nitrogen uptake, and striga (Striga spp.) infestation, using 874 ...

Grazing and cover crop effects on cover crop biomass and crop productivity during transition to organic production

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract We conducted a 4‐year organic transition field study to evaluate the effects of objective‐based cover crop mixtures and grazing on cover crop and forage biomass, residue, and carryover effects on the yield of the first organic certified crop.

Evaluating the Adapt‐N model for dynamic nitrogen recommendation in Brazilian maize (Zea mays L.) systems

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Aproveitamento pelo trigo do nitrogênio residual da crotalária (Crotalaria juncea) e da uréia aplicado ao solo em cultivo precedente Recovery by wheat of residual nitrogen from crotalária (Crotalaria juncea) and urea of previous crop soil fertilization

open access: yesCiência Rural, 2009
O cultivo de adubos verdes no sistema produtivo tem por objetivo o fornecimento de nitrogênio ao solo. Porém, muitas vezes os benefícios não são a curto prazo.

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...
