- 人口统计学 人口统计学
- 系统生物学 系统生物学
背景情况:
- 生命系统,包括社会昆虫,捍卫组织边界.
- 蜜蜂表现出复杂的防御策略:形态专业化,基于年龄的多元化和快速的任务切换.
- 了解生殖,发育和行为时间尺度的整合对于殖民地防御分配至关重要.
研究的目的:
- 研究生殖,发育和行为时间表如何整合,以平衡防御需求与其他殖民地需求.
- 模拟这些过程对Tetragonisca angustula任务分配和殖民地规模的影响.
- 阐明限制社会昆虫集体防御调节的人口因素.
主要方法:

Defenses Against Pathogens and Herbivores
23.8K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Modeling in Therapy
90
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Altruism

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
