The prehistoric populations of humans are an important source of information to analyze some aspects of the modern human societies. Thinking about the human ancestors it is important because it is possible to understand some of the characteristics of humans nowadays. For instance, human behavior or languages structures are some of the elements that could be studied by looking to human evolution...

Aim There is mounting concern that climate change will lead to the collapse of cyclic population dynamics, yet the influence of climate variability on population cycling remains poorly understood. We hypothesized that variability in survival and fecundity, driven by climate variability at different points in the life cycle, scales up from local populations to drive regional characteristics of p...

Evidence for synchronous fluctuations of spatially separated populations is ubiquitous in the literature, including accounts within and across taxa. Among the few mechanisms explaining this phenomenon is the Moran effect, whereby independent populations are synchronized by spatially correlated environmental disturbances. The body of research on the Moran effect predominantly assumes that enviro...

The determination of whether purse seine fishing in the Eastern Tropical Pacific is hampering the recovery of the northeastern offshore spotted dolphin and eastern spinner dolphin populations is a difficult problem. The question was not answered satisfactorily by a simple consideration of population abundance estimates, despite these estimates being made using innovative methods and great care ...

Ethnic minorities, such as Latinx people of Hispanic or Latino origin, and women earn fewer engineering degrees than Caucasians and men. With shifting population dynamics and high demands for a technically qualified workforce, it is important to achieve broad participation in the engineering workforce by all ethnicities and both genders. Previous research has examined the knowledge of and inter...

This paper examines the relationships among population dynamics, environment and economic development. We focus particularly on urbanization, whose impact is often characterized as strongly negative. We first examine the broad conceptual issues of population, urbanization, and environment, providing demographic insight to the understanding of the This Chapter is from the volume: de Sherbiniin, ...

Models are formulated for the population dynamics of a monoecious or dioecious species with an all-female parthenogenetic sibling species which is also gynogenetic. Continuous, deterministic reproduction and mortality, a stationary age distribution, random mating, and limited sexual competence for all individuals are posited. It is also supposed that in the dioecious case males do not distingui...

We propose an extension of the study of imitation in artefacts in which imitation takes place at the populationlevel. Instead of assuming a one-to-one teacher-student relation between agents, agents in our set-up take on no particular role and have to build up a repertoire of actions through imitative interaction with all other agents in the population. This allows us to study the sufficient an...
