A groundbreaking new perspective on collective behavior across biological systemsCollective behavior is everywhere in nature, from gene transcription and cancer cells to ant colonies and human societies. It operates without central control, using local interactions among participants to allow groups to adjust to changing conditions. The Ecology of Collective Behavior brings together ideas from evolutionary biology, network science, and dynamical systems to present an ecological approach to understanding how the interactions of individuals generate collective outcomes.Deborah Gordon argues that the starting point for explaining how collective behavior works in any natural system is to consider how it changes in relation to the changing world around it. She shows how feedback use-the means by which networks of interactions operate-and the organization of interaction networks evolve to reflect the stability and demands of the environment. Ant colonies function collectively, and the enormous diversity of species in different habitats provides opportunities to look for general ecological patterns. Through an in-depth comparison of ant species, Gordon identifies broad trends in how the diversity of collective behavior in many other collective systems reflects the dynamics of the environment.Shedding light on how individual actions give rise to group behavior, The Ecology of Collective Behavior explains the evolution of collective behavior through innovation in participant interactions, offering new insights into how collective responses function in changing conditions.

Recent trends in vehicle engineering are testament to the great efforts that scientists and industries have made to seek solutions to enhance both the performance and safety of vehicular systems. This Special Issue aims to contribute to the study of modern vehicle dynamics, attracting recent experimental and in-simulation advances that are the basis for current technological growth and future mobility. The area involves research, studies, and projects derived from vehicle dynamics that aim to enhance vehicle performance in terms of handling, comfort, and adherence, and to examine safety optimization in the emerging contexts of smart, connected, and autonomous driving.This Special Issue focuses on new findings in the following topics:(1) Experimental and modelling activities that aim to investigate interaction phenomena from the macroscale, analyzing vehicle data, to the microscale, accounting for local contact mechanics; (2) Control strategies focused on vehicle performance enhancement, in terms of handling/grip, comfort and safety for passengers, motorsports, and future mobility scenarios; (3) Innovative technologies to improve the safety and performance of the vehicle and its subsystems; (4) Identification of vehicle and tire/wheel model parameters and status with innovative methodologies and algorithms; (5) Implementation of real-time software, logics, and models in onboard architectures and driving simulators; (6) Studies and analyses oriented toward the correlation among the factors affecting vehicle performance and safety; (7) Application use cases in road and off-road vehicles, e-bikes, motorcycles, buses, trucks, etc.
