Screening of SNP Loci of Growth-related Candidate Gene and Genetic Diversity of Five Populations Based On Microsatellite Markers in Fujian Oyster, Crassostrea angulata [PDF]
, 2015 福建牡蛎(Crassostreaangulata，C.angulata)又名葡萄牙牡蛎，具有重要的经济价值和生态价值，但由于长期未经选育以及人工育苗的应用，导致牡蛎养殖出现经济性状衰退及死亡率逐年增高等现象，亟需加强种质资源保护，开展遗传改良研究。本研究利用单核苷酸多态性分子标记（singlenucleotidepolymorphism，SNP）对福建牡蛎生长相关的5个候选基因，即胰岛素相关多肽（insulinrelatedpeptides，IRPs）、ɑ-淀粉酶（ɑ-Amylase，ɑ-AMY ...

Exploration for effects of acoustic stimulus on movement behavior and HSP70 expression of two kinds of marine crustaceans [PDF]
, 2016 水下噪声会潜在的引起海洋生物紧张，分散和掩蔽这些海洋生物重要的声信号，进而对海洋生物的行为和生存造成影响。近几十年来，随着人类社会的不断发展，人们将发展目光投向了占有全球71%面积的海洋。伴随海洋事业的快速发展，海洋工程噪声对海洋生物的影响引起了人们的极大关注。虽然目前已有不少研究成果评估了水下工程噪声对海洋生物的影响，这些噪声包括轮船、打桩、地震勘探以及风电场等水下噪声，表明海洋工程等人为噪声对鱼类以及海洋哺乳动物都将造成了不同程度的影响和伤害。但是 ...

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Distribution of 210Po and 210Pb in the Prydz Bay and its adjacent sea areas and their estimate of particulate organic matter export [PDF]
, 2016 本研究依托中国第29次南极科学考察航次获得的210Po、210Pb数据，研究了普里兹湾及其邻近海域210Po、210Pb的生物地球化学行为，计算出颗粒有机物的输出通量，揭示了普里兹湾及其邻近海域的颗粒动力学特征。 普里兹湾及其邻近海域D210Po和D210Pb的比活度分别占到T210Po和T210Pb的90%以上，P210Po和P210Pb的份额不足10%。D210Po和D210Pb比活度在陆架区表现为低值，且由陆架向深海逐渐升高，反映了陆架区210Po、210Pb的清除作用强于陆坡及深海区 ...

Striking a balance: Stakeholder perceptions of risk in horse racing
Equine Veterinary Journal, Volume 58, Issue 3, Page 814-823, May 2026.Abstract Background Thoroughbred racing is a major industry, and in recent years public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1282-1292, May 2026.ABSTRACT Self‐regulated learning (SRL) as a key predictor of language learning has been widely studied, but few studies have examined it from a cross‐linguistic perspective. The present study investigated whether first language (L1) SRL strategy use transfers to second language (L2) SRL strategy use and the conditions under which this transfer occurs ...

Distribution characteristics and control factors of phosphate oxygen isotopes in plant samples [PDF]
, 2016 磷是植物生长必需的营养元素，但土壤中的植物可利用磷经常是受限制的。所以，土壤中需要额外施加磷肥才能保证植物正常生长。因此了解土壤-植物生态系统磷循环是非常有必要的。磷酸盐氧同位素δ18Op是了解磷循环的新型工具，δ18Op最早是用在古气候研究中，近年来逐渐用于水生生态系统、沉积物和土壤磷循环的研究中。尽管植物在土壤-植物系统磷循环中扮演着重要角色，但几乎所有的研究都忽略了δ18Op在植物中的研究。 本研究建立了植物水分提取方法-氮气吹扫捕集法。该法物理原理类似于传统方法-真空蒸馏法 ...
