概括
对白尾鹿 (Odocoileus virginianus) 的临时诱会改变它们的运动模式,增加它们在夜间的活动,但不会从它们的家园范围之外吸引它们. 移除诱并没有导致鹿离开已建立的地区,支持其在野生动物调查中的使用.
科学领域:
- 野生动物生态生态学
- 行为生态学 行为生态学
- 保护生物学 保护生物学
背景情况:
- 摄像头调查经常使用临时的诱来提高像白尾鹿 (Odocoileus virginianus) 这样的物种的检测率.
- 诱对鹿的空间使用和移动模式的影响,特别是在精细的时间尺度上,仍未得到充分研究.
研究的目的:
- 评估临时诱 (无皮玉米) 对白尾鹿空间使用和移动的影响.
- 为了确定诱的存在或移除是否会影响与对照组相对的鹿的行为.
主要方法:
- 在德克萨斯州中部的61只白尾鹿身上使用了GPS领 (15分钟间隔) 两年.
- 一般化的线性混合效应模型分析了范围大小,重叠,活动中心距离和前诱,诱和后诱期间的旅行距离.
- 鹿被分为冲击 (暴露于诱) 和对照组.
主要成果:
- 诱暴露导致在活跃期间 (夜间,夜间) 的家庭范围扩大,运动增加,但在不活跃期间 (白天) 的运动减少.
- 鹿没有转移活动中心向诱现场当诱存在.
- 诱被移除后,鹿在已建立的范围内继续食.
结论:
- 暂时的诱会以时间依赖的方式影响鹿的移动,但似乎不会从它们正常的家园范围之外吸引鹿.
- 移除诱不太可能导致鹿离开已建立的区域,从而保留野生动物调查的假设.
- 调查结果为野生动物管理策略提供了关于使用诱及其对鹿行为的影响的信息.

Selected Data About Geographic Locations
263
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Role of Affect in Interpersonal Attraction
217
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The Influence of Affect on Cognition
269
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect
195
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Background and Environment Affect Phenotype
7.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

State Space Representation

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.
