Consider the feeding and foraging behavior of chimpanzees and mountain gorillas 比较黑猩猩和大猩猩的进食及觅食的行为。
9 . the foraging behavior of e . balteatus de geer larvae changes gradually at different aphid densities . when the aphid density changed from low to high , the 在猎物密度低时,搜索活动提高,处置时间较高;在猎物密度高时,搜索活动则下降,处置时间较低。
These differences were analyzed to show that the echolocation calls will change greatly so as to adapt to the different flying style , foraging behavior and habitats of bats . 3 蝙蝠不同状态下回声定位声波存在差异的分析说明,蝙蝠的回声定位声波能够产生较大的变异,其意义在于适应其不同的飞行方式、捕食策略和栖息环境以及捕食猎物的体型大小。
In this paper , predation , starvation endurance ability , foraging behavior of e . balteatus and the effect of different aphides on its growth and development , have been studied . the main results are as follows : 1 本文研究了黑带食蚜蝇的捕食行为、搜索行为及激发因子、饥饿耐受性、功能反应、捕食作用及影响因素、不同猎物对黑带食蚜蝇生长发育的影响等。
In several studies , researchers correlated the amount of salmon - derived nitrogen or carbon directly with the movements of bears , providing further evidence that their foraging behavior is the mechanism that delivers the salmon nutrients to riparian plants 而好几项研究中,研究人员都认为鲑鱼带来的氮或碳的多寡,与熊的活动有直接相关,进一步证实了熊的觅食行为,是将鲑鱼养份传递给河岸植物的机制。
The paper present an in - depth analysis about existence possibility , orientation , degree , limits of water physiology integration of clonal plants and their relation to such behaviors as functional differentiation , phenotypic plasticity and foraging behavior and risk spreading , and systematically summarizes and comments on the latest research advances about water integration of clonal plants 本文主要从理论上对克隆植物水分生理整合的存在性、方向性、整合的程度、范围及其与克隆植物的功能分工、表型可塑性和觅养行为、风险分摊等行为表现的关系进行了深入分析,并对迄今有关克隆植物水分整合的最新研究进展和研究方法进行了系统总结和评述。
The larvae fed by macrosiphum avenae ( f . ) , rhopalosiphum padi ( l . ) , myzus persicae ( sulzer ) and aphis citricola have not some difference on the larva weight , the pupa weight , growth and development . 6 . the most frequent sequence of the foraging behavior of e . balteatus is : searching ? capture ? consumption - cleansing - break - searching 明确了麦长管蚜、禾谷缢管蚜rhopalosiphumpadi ( l ) 、烟蚜myzuspersicae和绣线菊蚜aphiscitricola对黑带食蚜蝇的生长发育无不良影响,是其较适合的食物;而甘蓝蚜brevicorynebrassicae饲喂的黑带食蚜蝇幼虫存活率低,常不能正常化蛹,是其不适宜的食物。
This paper firstly focused on and evaluated the pollination characteristics of c . praecox , in half - natural habitat of nanjing . we investigated flowering phenology , flowering patten , pollen viability , stigma receptibility , species of visitors , visiting rate of visitors and their foraging behavior . and we also investigated its breeding system , including pollen - ovule ratio ( p / 0 ) , out - crossing index ( oci ) , pollen grains deposited in stigmas , pollen germination rate and seed set rate with different treatments , from 2002 to 2004 试验分别在2002 - 2003年和2003 - 2004年冬季进行,研究内容包括:花期物候观察、花部形态观察和统计、雌雄配子体功能测定、访问昆虫种类、访问行为、访花频率和效率;同时对蜡梅繁育系统进行了检测,检测内容包括花粉胚珠比( p / 0 ) 、杂交指数( oci )及不同处理花粉萌发率及结实率检测等等,同时还进行了蜡梅与亮叶蜡梅传粉过程比较。
Before the formation of leaves , the nutrition for the development of viviparous plantlet is supplied by its parent , which is a kind of typical foraging behavior . but as to parents , it is a kind of parental breeding behavior and altruism . when talking about heredity and fitness , such a kind of altruism is a sort of egoism too 在胎生苗叶片产生以前,它的营养全部由母体提供,属于全异养阶段,这是一种典型的觅源行为;从母体的角度来看,这又属于一种亲代哺育行为与利他行为;而从遗传与适合度的角度考虑,母体的这种利他行为同时也是一种利己行为。
