Gravity, Cosmology, and Astrophysics : A Journey of Exploration and Discovery with Female Pioneers
This open access book provides graduate students and scientists with fundamental knowledge on the mechanics of granular suspensions as well as on the mathematical and numerical techniques that can be adopted to investigate geophysical flows.To this end, three formidably complex problems (sediment transport, flow-like landslide inception, and gravity currents) are considered.The reader will find a thorough combination of elements of fluid and solid mechanics, rheology, geotechnics, geomorphology, civil, and coastal engineering.The first part of the book introduces the problem of granular suspensions from the mathematical viewpoint, focusing on issues that characterise geophysical flows such as turbulence, the effects of inter-particle contacts, and strong velocity gradients.In the second part, different models that were successfully used to investigate the mechanics of granular suspensions in environmental flows are presented.

Why does adaptive radiation occur through allopatric speciation processes?
Adaptive radiation occurs through allopatric speciation processes because when a population becomes geographically isolated, different environmental conditions and selective pressures can lead to the evolution of new traits and adaptations. This can result in the rapid diversification of species as they adapt to their specific habitats and niches. Over time, this can lead to the emergence of multiple new species with distinct characteristics, allowing them to occupy different ecological roles and reduce competition among them.
-
What is the difference between allopatric and sympatric speciation?
Allopatric speciation occurs when a population is separated by a physical barrier, such as a river or mountain range, leading to the evolution of two separate species. In contrast, sympatric speciation occurs when a new species evolves within the same geographic area as its parent species, without any physical barriers. Sympatric speciation often involves factors such as ecological, behavioral, or genetic differences driving the formation of a new species within the same habitat.
-
Does allopatric speciation always occur only through geographic isolation?
No, allopatric speciation does not always occur only through geographic isolation. While geographic isolation is a common mechanism for allopatric speciation, it is not the only way that populations can become reproductively isolated. Other factors such as ecological or behavioral differences can also lead to reproductive isolation and ultimately speciation, even in the absence of physical barriers. For example, if two populations of a species inhabit different ecological niches and do not interbreed due to differences in their behaviors or mating preferences, they can still undergo allopatric speciation without being geographically isolated.

What is the difference between allopatric speciation and adaptive radiation?
Allopatric speciation occurs when a population is geographically isolated from one another, leading to genetic divergence and the formation of new species. This isolation can be caused by physical barriers such as mountains or bodies of water. On the other hand, adaptive radiation is the rapid diversification of a single ancestral species into multiple new species, often due to the colonization of new environments or the exploitation of new ecological niches. While allopatric speciation is driven by geographic isolation, adaptive radiation is driven by ecological opportunity and the exploitation of diverse habitats.

Ethical Public Leadership : Foundation, Exploration, and Discovery
Dozens of books are published each year on leadership, but as pundits, scholars, philosophers, and public intellectuals note, what is written is too often shallow and facile, oriented toward quick fixes for performance enhancement or internal organizational and personnel development.Drawing from a diverse range of literature, including history, philosophy, public administration, leadership, religion, and spirituality, this book fills an important gap, exploring what it means to be an ethical and moral leader.It takes a deep dive into the many challenges of leadership, examining the continuing contrast between bureaucracy and democracy, the unique ethical and moral characteristics of nonprofit and faith-based organizations, and the globalization of organizations and institutions. Throughout the book, author Stephen M. King develops a more holistic and interdisciplinary understanding of ethical and moral leadership, required for more thoughtful theoretical and empirical research.He points students of leadership to the time-honored values of ethics and morality, reestablishes the ethical balance between bureaucracy and democracy, and helps reorient the values' purpose of public, nonprofit, and global institutions, providing hope of a better future for leadership.Ethical Public Leadership is required reading for students of public administration and nonprofit management, as well as for practicing public servants and nonprofit sector employees at all levels.

What is the difference between adaptive radiation and allopatric speciation?
Adaptive radiation is a process in which a single ancestral species diversifies into a variety of different species, each adapted to a specific ecological niche. This can occur when a new environment or ecological opportunity becomes available, leading to the rapid evolution of multiple new species. Allopatric speciation, on the other hand, occurs when a population is divided into separate, geographically isolated subpopulations, leading to the evolution of distinct species due to genetic drift, natural selection, and other evolutionary forces acting independently in each population. While adaptive radiation can occur in allopatric speciation, it can also occur in other speciation processes such as sympatric speciation.

How does allopatric speciation occur between the silver gull and the herring gull?
Allopatric speciation occurs between the silver gull and the herring gull when a physical barrier, such as a body of water, separates the two populations. This isolation prevents the two populations from interbreeding and exchanging genetic material. Over time, the isolated populations accumulate genetic differences through mutation, genetic drift, and natural selection, leading to the formation of distinct species. As a result, the silver gull and the herring gull evolve separately and become reproductively isolated from each other, ultimately leading to the formation of two distinct species.

How has the species diversity in cichlids in Lake Tanganyika arisen through allopatric speciation?
The species diversity in cichlids in Lake Tanganyika has arisen through allopatric speciation, which occurs when a population is geographically isolated and evolves separately from the original population. In the case of Lake Tanganyika, the lake's complex and varied habitat has led to the formation of different isolated populations of cichlids. Over time, these isolated populations have evolved unique traits and characteristics, leading to the formation of new species. The geographical isolation and the diverse ecological niches within the lake have allowed for the rapid diversification of cichlids through allopatric speciation.

How does allopatric speciation occur between the herring gull and the lesser black-backed gull?
Allopatric speciation between the herring gull and the lesser black-backed gull occurs when a physical barrier, such as a body of water, separates the two populations. This isolation prevents gene flow between the two groups, leading to genetic divergence over time. As each population adapts to its specific environment and evolves independently, they accumulate enough genetic differences to become distinct species. Eventually, if the populations come back into contact, they may be reproductively isolated due to their genetic differences, completing the speciation process.
