Mating status-dependent "choice" in competitive and noncompetitive arenas [0.03%]
竞争与非竞争场境下交配状态相关的“选择”现象
Robert J Dugand,Rowan A Lymbery,Nirjana Dewan et al.
Robert J Dugand et al.
To maximize their reproductive fitness, females of many polyandrous species should display mating status-dependent choice, where they mate relatively indiscriminately once to ensure reproductive output, and then become choosy and mate prefe...
Response to intruder number is related to spontaneous quantity discrimination performance in a wild bird [0.03%]
入侵者数量的反应与野生鸟类的自发数量辨别表现有关

Grace Blackburn et al.
Quantity discrimination abilities are considered a valuable skill for many aspects of life, including foraging, predator avoidance, and intergroup contests. Two types of experiments are often utilized to detect such abilities in animals; co...
Divergent alternative mating tactics in convergent male reproductive morphs [0.03%]
趋同的雄性生殖表型下的发散交配对策

Alternative reproductive phenotypes involve polymorphic behaviors and forms within sexes. Testing whether behavioral variants such as alternative tactics (eg sneaking or satellite behavior) are initially co-expressed or decoupled from morph...
Corticosterone-implanted chicks transmit stress to parents and neighbors in a colonial seabird [0.03%]

In animals living in groups, stress-induced changes in behavior can be a source of social information, and stressed individuals can potentially become stressors for other social partners, with important consequences for social and populatio...
Parental control: ecology drives plasticity in parental response to offspring signals [0.03%]
亲代抚育控制：生态驱动的后代信号诱导亲代反应的可塑性
Birds differ in their parent-offspring interactions, and these differences may be caused by environmental variation. When food is plentiful, the chicks that are begging the most are fed the most. When food is scarce, parents instead feed th...

Individuals of a species cope with environmental variability through behavioral adjustments driven by individuals' responsiveness to environmental stimuli. Three key empirical observations have been made for many animal species: The coexist...

To balance the basic needs of organisms, internal and external cues are used to inform the optimal behavioral strategy. Some of the best-studied related cognitive rules have emerged in predator-prey contexts, such as the threat-sensitivity ...
Interannual variation in foraging decisions in chick-rearing black-legged kittiwakes [0.03%]
以黑脚三趾鸥育雏期觅食行为的年际变化为例分析栖息地选择的决定因素
Philip Bertrand,Joël Bêty,Nigel Gilles Yoccoz et al.
Philip Bertrand et al.
Long-lived species must balance allocation between reproduction and self-maintenance, and such a trade-off is expected to affect their foraging behavior. A bimodal foraging strategy, where individuals alternate between long trips for self-m...
Heterospecific territorial defense in tit species varies according to breeding habitat overlap [0.03%]
Coal山雀属物种的异种领地防御取决于繁殖栖息地重叠程度
Alessandro Berlusconi,Giulia Castiglione,Erminio Clerici et al.
Alessandro Berlusconi et al.
The coexistence of species within the same guild is promoted by ecological and behavioral mechanisms, particularly niche differentiation. When niches overlap, coexistence may be maintained through spatial segregation, achieved through inter...
Passive debris cloaking in beetles provides non-visual camouflage against predatory ants [0.03%]
甲虫被动伪装垃圾以对抗捕食蚂蚁
K Greig,T R Buckley,R A B Leschen et al.
K Greig et al.
Our understanding of visual camouflage has increased dramatically in recent years, however we know less about anti-predator defenses that exploit senses other than vision. Low light habitats, such as leaf litter, are more commonly dominated...
