Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段
Ecological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

野生动物学报, 2013 大美洲鸵,现已被列入IUCN世界濒危动物红色名录（NT）。近年来,众多动物园饲养管理人员对大美洲鸵的饲养管理进行了深入的研究,但有关大美洲鸵人工孵化技术的研究尚属于空白阶段。本研究基于1998年至今的孵化经验和实践操作,着重从大美洲鸵卵的处理、孵化前准备及孵化技术3个方面内容进行探讨。研究显示:1)种卵的新鲜度、形状、大小、重量、卵壳厚度、消毒过程等因素对孵化成功率有直接影响;2)待孵的大美洲鸵的种卵,贮存温度控制在1520℃间,相对湿度约70%75%,入孵时必须对种卵进行6 h左右的预热处理;3 ...

Functional Ecology, Volume 40, Issue 4, Page 800-815, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

ウシ裸化卵子の成熟に及ぼす成長因子(EGF, IGF-I, インスリン)の影響 [PDF]
, 1998 ウシの卵巣から採取した卵丘細胞卵子複合体から卵丘細胞を除去した裸化卵子を種々の濃度の成長因子(EGF, IGF-I, インスリン)を添加した培地で24時間培養した. いずれの成長因子を添加した場合にも無添加の対照区に比べて有意に高い成熟卵率が得られた. 卵巣から採取する時に既に裸化していた卵子の成熟卵率においては, 培地にEGFを添加した影響は認められなかった.
