    The effect of maternal experience on the maturing of early behavior reactions and species-specific defensive behavior (dark preference reaction) in the offspring of Wistar rats was investigated. We found differences between maternal behavior of primiparous females and the same females after second parturi- tion. The behavior of experienced female is characterized by maintenaning a more comfortable state in the nest, and more care for the offspring. The study of the dynamic of behavior in the offspring of primiparous females revealed the disappearance of the correlation between the timing of opening the eyes and the appearance of the first offspring behavioral responses, which is a negative factor for the formation of adaptive behavior in ontogenesis. A violation of the development of a species-specific defensive behavior (dark preference reaction) was found in the offspring of naive females. The results indicate a positive in- fluence of motherhood experience on the formation of functions of their offspring.

    Formation of Species

    Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

    Keystone Species

    Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

    What is Behavior?

    Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

    Causes of Social Behavior III: Biological and Environmental Influences

    Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...
