This study investigates variation in collective behavior in a natural population of colonies of the harvester ant, Pogonomyrmex barbatus. Harvester ant colonies regulate foraging activity to adjust to current food availability; the rate at ...

Sexually reproducing organisms should mate with the highest quality individuals that they can. When female songbirds choose a mate, they are thought to use several aspects of male song that reflect his quality. Under resource-limited enviro...
Feeding decisions of eastern bluebirds are situationally influenced by fledgling plumage color [0.03%]

The relative amount of resources that avian parents provide to individual offspring within a brood represents a strategy that can have large effects on reproductive success. We tested whether parental feeding decisions of eastern bluebirds ...
Examination of prior contest experience and the retention of winner and loser effects [0.03%]
以往竞赛经历对胜负体验保持效果的影响研究

In many animal taxa, prior contest experience affects future performance such that winning increases the chances of winning in the future (winner effect) and losing increases the chances of losing in the future (loser effect). It is, howeve...

Anthropogenic disturbances of wildlife, such as noise, human presence, hunting activity, and motor vehicles, are becoming an increasing concern in conservation biology. Fireworks are an important part of celebrations worldwide, and although...
Water-seeking behavior in worm-infected crickets and reversibility of parasitic manipulation [0.03%]
感染丝虫的蟋蟀求水行为及寄生操纵的可逆性研究
Fleur Ponton,Fernando Otálora-Luna,Thierry Lefèvre et al.
Fleur Ponton et al.
One of the most fascinating examples of parasite-induced host manipulation is that of hairworms, first, because they induce a spectacular "suicide" water-seeking behavior in their terrestrial insect hosts and, second, because the emergence ...
Queen reproductive state modulates pheromone production and queen-worker interactions in honeybees [0.03%]
蜂后生殖状态可以调节蜜蜂种群信息素的产生及蜂后与工蜂之间的相互作用
Sarah D Kocher,Freddie-Jeanne Richard,David R Tarpy et al.
Sarah D Kocher et al.
The mandibular glands of queen honeybees produce a pheromone that modulates many aspects of worker honeybee physiology and behavior and is critical for colony social organization. The exact chemical blend produced by the queen differs betwe...
Increased host aggression as an induced defense against slave-making ants [0.03%]
:host对奴役蚂蚁的诱导防卫反应——增强宿主攻击行为
Tobias Pamminger,Inon Scharf,Pleuni S Pennings et al.
Tobias Pamminger et al.
Slave-making ants reduce the fitness of surrounding host colonies through regular raids, causing the loss of brood and frequently queen and worker death. Consequently, hosts developed defenses against slave raids such as specific recognitio...
A behavioral mechanism underlying ecological divergence in the malaria mosquito Anopheles gambiae [0.03%]
非洲疟疾蚊Anopheles gambiae生态分化背后的behaviour机制

Geoffrey Gimonneau et al.
Disruptive selection mediated by predation on aquatic immature stages has been proposed as a major force driving ecological divergence and fostering speciation between the M and S molecular forms of the African malaria mosquito, Anopheles g...
