Macromolecular Rapid Communications, EarlyView.Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

Diurnal Variations in the Upstream Migration of Adult Masu Salmon (Oncorhynchus masou) in Rivers of Hokkaido during the Spawning Season [PDF]
, 2002 産卵期におけるサクラマス親魚の遡上活動の日周変動について、十勝川水系猿別川と尻別川水系目名川の下流に位置するサケマス捕獲場で観察した。サクラマスの遡上活動は日中に活発化して夜間にはほとんど移動しないのに対し、同時に採捕されたサケおよびカラフトマスは夜間にも遡上し、日中の遡上時間帯もサクラマスとサケ間で有意に異なった。上流域を産卵場として選択するサクラマスの遡上行動は、流れの中で遡上障害物を視覚で認識することの出来る日中に活発化すると考えられた。Diurnal variations of adult ...

Skewed genetic sex ratio in reciprocal hybrids between pink salmon and masu salmon
, 2021 サケ科魚類の人為雑種において，性比が一方に偏る例が報告されてきたが，これらは生殖腺の表現型に基づく。本研究では，カラフトマスとサクラマス間の正逆雑種について，雄特異的な性決定遺伝子sdYの有無による遺伝的性を検討した。その結果，カラフトマス雌×サクラマス雄，サクラマス雌×カラフトマス雄の8か月齢魚の遺伝的性は雌に，サクラマス雌×カラフトマス雄の12か月齢魚は雄に偏った。初期胚と孵化仔魚の遺伝的性比は1:1であったことから雑種の性比の偏りは成長過程における生残率の雌雄差により生じたと考えられた ...

Amanita theophili sp. nov. (Amanitaceae) from central Mexico
Nordic Journal of Botany, EarlyView.Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

Asymmetric Hybridization and Introgression between Pink Salmon and Chinook Salmon in the Laurentian Great Lakes [PDF]
, 2000 Among Pacific salmon collected in the St. Marys River, five natural hybrids of pink salmon Oncorhynchus gorbuscha and chinook salmon O. tshawytscha and one suspected backcross have been detected using morphologic, meristic, and color evidence.

Nordic Journal of Botany, EarlyView.Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.
