Chapter 15 Biogeography and Dispersal
Chapter 15 Biogeography and dispersal Rob Hengeveld and Lia Hemerik Introduction This chapter evaluates the role of dispersal in biogeographical processes and their re- sulting patterns. We consider dispersal as a local process, which comprises the com- bined movements of individual organisms, but which can dominate processes even at the scale of continents. If this is correct, it is no longer possible to separate local ecological processes from those at broad, geographical scales. However, biogeo- graphical processes differ from those happening in one or a few localities; at the broader scales,there are additional processes occurring which are only evident when examined from this wider perspective. We integrate biogeography with ecology, explaining broad-scale effects, ranging from processes happening locally as the result of responses of individual organisms to perpetual changes in living conditions in heterogeneous space. The models to be used cannot be those traditional in population dynamics with a dispersal parameter plugged in, but must be spatially explicit. Only a broad-scale perspective of con- tinual redistribution of large groups of individuals or reproductive propagules can give dispersal its biological and biogeographical significance. Our general thesis in this chapter is that adaptation in non-uniform space enables individuals to cope effectively with environmental variation in time. In our analyses of spatially adaptive processes, we concentrate on principles rather than on details of specific phenomena, such as types of distance distribution. We therefore formulate these principles in terms of simple Poisson processes.In spe- cific cases, these distributions can be replaced by more complex ones which may fit better. -

Recent invaders tend to produce fewer, but larger, juveniles, delay the onset but increase the duration of reproduction, survive longer, and senesce more slowly than earlier ones. These traits are associated with higher ranks in a competitive hierarchy established in a previous study. However, the endemic species, now nearly extinct in the island, is inferior to the other three with respect to both competition and colonization traits, violating the trade-off assumption.

ABSTRACT: Special operations are conducted more than ever in modern warfare. Since the 1980s they have developed and grown in numbers. But with more attempts of operations and bigger numbers, comes failures. One of these failures is operation Red Wings where a unit of US Navy SEALs at- tempted a recognisance and raid operation in the Hindu Kush. The purpose of this paper was to see how that failure could be analysed from an existing theory of Special operations. This was to ensure that other failures can be avoided but mainly to understand what really happened on that mountain in 2005. The method used was a case study of a single case to give an answer with quality and depth. The study found that Mcravens theory and principles of how to succeed a special operation was not applied during the operation. The case of operation Red Wings showed remarkable valour and motivation, but also lacked severely when it came to simplicity, surprise, and speed.

The Basics of Population Dynamics Greg Yarrow, Professor of Wildlife Ecology, Extension Wildlife Specialist Fact Sheet 29 Forestry and Natural Resources Revised May 2009 All forms of wildlife, regardless of the species, will respond to changes in density dependence. These concepts are important for landowners habitat, hunting or trapping, and weather conditions with fluctuations and natural resource managers to understand when making decisions in animal numbers. Most landowners have probably experienced affecting wildlife on private land. changes in wildlife abundance from year to year without really knowing why there are fewer individuals in some years than others. How Many Offspring Can Wildlife Have? In many cases, changes in abundance are normal and to be expected. Most people realize that some wildlife species can produce more The purpose of the information presented here is to help landowners offspring than others.

Remote Controlled Restraint The Effect of Remote Warfighting Technology on Crisis Escalation Erik Lin-Greenberg Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2019 © 2019 Erik Lin-Greenberg All rights reserved ABSTRACT Remote Controlled Restraint: The Effect of Remote Warfighting Technology on Crisis Escalation Erik Lin-Greenberg How do technologies that remove warfighters from the front lines affect the frequency and intensity of military confrontations between states? Many scholars and policymakers fear that weapons that reduce the risks and costs of war – in blood and treasure – will lead states to resort to force more frequently during crises, destabilizing the international security environment. These concerns have featured prominently in debates surrounding the proliferation and use of remote warfighting technologies, such as drones. This project sets out to evaluate whether and how drones affect crisis escalation. Specifically, do drones allow decisionmakers to deploy military forces more frequently during interstate crises? Once deployed, how do these systems affect escalation dynamics? I argue that drones can help control escalation, raising questions about scholarly theories that suggest the world is more dangerous and less stable when technology makes conflict cheaper and less risky. At the core of this project is a theory of technology-enabled escalation control. The central argument is that technologies like drones that remove friendly forces from the battlefield may lead states to use force more frequently, but decrease the likelihood of escalation when used in lieu of inhabited platforms. More specifically, these technologies lower the political barriers to initiating military operations during crises, primarily by eliminating the risk of friendly force casualties and the associated domestic political consequences for launching military operations. -

We employ a Kernel Regularized Least Squares (KRLS) machine learning technique and econometric methods such as Dynamic Ordinary Least Squares (DOLS), Fully Modified Ordinary Least Squares (FMOLS) regression, the Mean-Group (MG) and Pooled Mean-Group (PMG) estimation models. The econometric techniques confirm the Environmental Kuznets Curve (EKC) hypothesis between income level and CO2 emissions while the machine learning method confirms the scale effect hypothesis. We find that while CO2 emissions, population and income level spur energy demand and utilization, economic development is driven by energy use and population dynamics. This demonstrates that income, population growth, energy and CO2 emissions are inseparable, but require a collective participative decision in the achievement of the SDGs. -

ON THE BRIGHT, sunny morning of September 11, 2001, as tens of thousands of workers were beginning a day’s work in lower Manhattan, a commercial airliner crashed into the side of one of the two towers of the World Trade Center, the tallest buildings in New York. The collision created a huge explosion and an intense fi re. Less than half an hour later, as thousands of workers fl ed the burning building, another commercial airliner rammed into the companion tower, creating a second fi reball. Within an hour after that, the burning fl oors of both towers gave way and fell onto the fl oors below them, pulling one of New York’s (and America’s) most famous symbols to the ground. At about the same time, in Washington, D.C., another commercial airliner crashed into a side of the Pentagon—the headquarters of the nation’s military—turning part of the building’s façade into rubble. -

OPERATION RED WINGS – The (Mis)Information Aftermath Copyright © Ed Darack, 2010, All Rights Reserved – For The Marine Corps Gazette Ed Darack – www.darack.com – [email protected] Published in the January, 2011 issue of the Marine Corps Gazette, Page 62 NOTE: The editors at the Gazette changed the subtitle from “The (Mis)Information Aftermath” to “What Really Happened?” “Don’t let the truth ruin a good story.” – Origin unknown OVERVIEW: The events of OPERATION RED WINGS, which spiraled into disaster shortly after the insert of a four-man Naval Special Operations Forces (NAVSOF) reconnaissance and surveillance team (R and S team) during the opening phase of the operation, present warfighters (and those covering military operations) with a broad array of vital contemporary case studies relevant to those functioning at the battalion staff, company, platoon, and squad levels. These include studies in deconfliction between conventional and special operations forces, the paramount necessity of unity of command / effort, communication in complex mountainous terrain, mountain ambush tactics, and the importance of comprehensive, detailed planning, among others. Despite these lessons (the knowledge of which will arguably save lives in future operations), little has been discussed in professional military papers about OPERATION RED WINGS. However, much has been written and discussed about RED WINGS in general media (which is often referenced by warfighters for their ongoing professional military education), and much of this, including the content of two books on the topic, is rife with misinformation. BACKGROUND, KEY POINTS, AND AFTERMATH OF OPERATION RED WINGS: In November, 2004, 3d Battalion, 3d Marines (3/3) arrived in RC-East (Regional Command – East, Afghanistan) and assumed responsibility of their area of operations (AO), which included the restive Kunar Province.
