总之，如此不同的投资差异是在捕食压力和种间竞争作用下以及亲鸟为满足鸟卵胚胎和雏鸟迅速生长发育的必要条件下，各种生物学特征协调的结果。

At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4cm burial under soil covered by litter.
结果表明：秋季鼠类对种子的捕食压力大，使得种子在无保护的情况下很少存活到出苗；而秋季覆网保护和完全保护（覆网一直保留到第二年10月调查时为止）均增加了直播种子的存活和出苗率；将种子埋藏在土壤1-4cm也显著增加直播种了的存活率和出苗率，这与鼠类密度(12%)在秋季显著高于春季(2%)有直接关系。

Hong Young YAN pointed out, ibid., squids and octopi are the two major cases of cephalopod. Squids are found everywhere in the five oceans, and never observed as endangered under human's mass hunting and the natural enemies' threat, which means they must be in possession of fine "sense" to protect themselves from dangerous environment.
严宏洋指出，乌贼和章鱼是头足类动物最具代表性的两大族群，乌贼分布全球五大洋，且在人类大量猎补及天敌捕食的情况下仍未显濒绝，显示它们应有优良的「感觉系统」，能在危险的环境压力下繁衍无碍。

Based on these observations, we hypothesised that (1) the length of the breeding season, food resources and predation are critical for the evolution of passerine reproductive patterns in alpine meadows;(2) that alpine meadow passerines used single-investment and accumulative-investment strategies;(3) that the typical clutch size was actually the most efficient for reproductive purposes;(4) and that the transition from neonate to fledgling passerines is a relatively fixed process as compensatory growth does not appear to occur;(5) and that growth period is volatile.
高寒草甸雀形目鸟类受适合繁殖季节长度、食物资源和捕食压力的影响，或选择逐步投资对策，或选择一次投资对策；每个种群的常见窝卵数就是最适窝卵数；雏鸟的发育模式相对固定，不存在补偿性生长，但是生长期长度是可变化的。

The inducible nitric oxide synthase is obviously expressed in speen of rats under the predator stress, suggesting important function for iNOS in speen physiology. However, the expression and subcellular localization for NOS in speen development and differentiation are largely unknown. In the present study, the changes in iNOS activity in spleen of rats under predator stress were studied to explore the role of iNOS in the decreased immunoactivity of the stressed rats. The changes in iNOS were observed with immunobistochemical method, and the contents of NOS and NO in spleen with biochemical method.
在捕食压力下，大鼠脾脏诱导型一氧化氮合酶明显表达，说明iNOS起到了重要的生理功能，然而，NOS的表达及在亚细胞水平的定位以及相应的差异变化等都很不明确，本试验采用捕食应激模型，利用免疫组织化学方法和生化测定，检测心理性应激对大鼠脾脏iNOS活性的影响及探讨这种影响与应激动物免疫力下降之间的关系。
-
Biomass of calanoids was low when fish predation was intensive, probably because their nauplii were more vulnerble.
在鱼类捕食压力较高的水体中哲水蚤的生物量较低，因为无节幼体较容易被鱼类所捕获。

At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.
随着邻体数目的增加，病毒的感染力度变得更大而且在空间上形成聚集的波形；(5)生境破坏及其空间结构在一定范围内有利于疾病的控制，这暗示人为对生境的干扰可作为疾病控制的一个潜在方法；(6)生境破坏的数量以及不同类型生境的空间分布格局都显著地影响了寄生病毒的入侵和传播，生境破碎化程度越高(高丧失斑块的数量或低聚集程度)，将越有害于病毒的入侵和传播，这暗示了空间异质性是否有益于物种的入侵依赖于所考虑的生态过程；(7)由生境破坏引起的空间异质性的两个组分之间存在负偶联关系trade-off(8在适度的生境破坏范围内，宿主种群能够平衡生境破坏带来的正负两种效应并呈现增长趋势；(9)在捕食-食饵系统中，寄生感染病毒极有可能在生境破坏量较低时爆发；(10)物种在面临生境破坏或者其它环境压力时表现出更高的聚集分布策略；(11)寄生-宿主/食饵-捕食生态传染病系统与共位捕食食物网结构具有相似的生物机制，其中捕食者扮演共位捕食者的角色，已感染食饵作为共位食饵，易感染食饵扮作共同消耗的资源；(12)位于最高营养级水平的种群对生境破坏的响应不一定是最敏感的，这不仅依赖于内在的生物机制同时也依赖于外在的环境干扰。

Biomass of M. micrura and C. vicinus increased with increased trophic level of the lake water, while biomass of large-bodied cladocerans (D. galeata and Leptordora kindti) decreased with increased fish predation, and relative abundance of calanoids to cyclopoids tended to decrease with increased fish predation.
微型裸腹溞与近邻剑水蚤的优势度随水体营养水平的上升而上升，而大型枝角类（盔型透明溞与透明薄皮溞）的优势度随水体中鱼类捕食压力的上升而下降，哲水蚤相对于剑水蚤的优势趋向于随鱼类捕食压力的上升而下降。
