Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Intercropping of legumes with cereals enhances resilience, resource efficiency, and nutritional quality in food systems, yet few studies have integrated yield stability with grain quantity and post‐harvest processability. Lentils (Lens culinaris Medik.) and hull‐less barley (Hordeum vulgare L. var.

PLANTS, PEOPLE, PLANET, EarlyView.Fonio (Digitaria exilis and Digitaria iburua) cereals are valued for their drought resilience, adaptability to poor soils, and cultural importance. In Nigeria, where both species are cultivated, fonio has declined due to labor‐intensive processing, lower yields, and changing livelihood choices. By documenting 21 landraces (15 D. exilis and 6 D. iburua),

Wildlife Letters, EarlyView.The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

Relation between calcium metabolism of pearl sac and pearl quality [PDF]
, 1972 1) 真珠袋上皮細胞の Ca 代謝を支配する因子を移植実験および養殖実験によって調査し，個体のもつ特質，生活力，生理状態，および環境と時間の経過に対応した貝の生理が真珠袋の Ca 代謝にどんな形で影響し，真珠の物性（品質）に反映するかを生鉱物学的立場から論じた。 2) ある環境条件のもとで貝は種に特有な Ca 代謝能力をもっているが，各個体についてみると外套膜外面上皮細胞の Ca 代謝能力は個体間でわずかではあるが個体差が認められる。したがって，真珠袋上皮細胞の Ca ...

Studies on the histology of the pearl-sac, VII. Behavior of the meta-chromatic substance [PDF]
, 1961 1) 真珠層を分泌している真珠袋組織についてトルイジンブルー染色により粘液物質の行動を追跡した。 2) 真珠袋上皮の基底部の結合組織中にある粘液細胞はメタクロマジー物質を真珠袋内に分泌する。分泌と同人に果粒状の物質は粘液となる。粘液層は真珠層の前駆物質と考えられる。The observations on the behavior of the metachromatic substance of pearl-sac tissues were carried out on the sectioned ...
