Patterns in Nature - The Analysis of Species Co-occurrences

James G. Sanderson, Stuart L. Pimm

Beschreibung

What species occur where, and why, and why some places harbor more species than others are basic questions for ecologists. Some species simply live in different places: fish live underwater; birds do not. Adaptations follow: most fish have gills; birds have lungs. But as Patterns in Nature reveals, not all patterns are so trivial. Travel from island to island and the species change. Travel along any gradient—up a mountain, from forest into desert, from low tide to high tide on a shoreline —and again the species change, sometimes abruptly. What explains the patterns of these distributions? Some patterns might be as random as a coin toss. But as with a coin toss, can ecologists differentiate associations caused by a multiplicity of complex, idiosyncratic factors from those structured by some unidentified but simple mechanisms? Can simple mechanisms that structure communities be inferred from observations of which species associations naturally occur? For decades, community ecologists have debated about whether the patterns are random or show the geographically pervasive effect of competition between species. Bringing this vigorous debate up to date, this book undertakes the identification and interpretation of nature’s large-scale patterns of species co-occurrence to offer insight into how nature truly works.Patterns in Nature explains the computing and conceptual advances that allow us to explore these issues. It forces us to reexamine assumptions about species distribution patterns and will be of vital importance to ecologists and conservationists alike.

Drift Into Failure - From...

Sidney Dekker

What does the collapse of sub-prime lending have in common with a broken jackscrew in an airliner’s tailplane? Or the oil spill disaster in the Gulf of Mexico with the burn-up of Space Shuttle Columbia? These were systems that drifted into failure. While pursuing success in a dynamic, complex environment with limited resources and multiple goal conflicts, a succession of small, everyday decisions eventually produced breakdowns on a massive scale. We have trouble grasping the complexity and normality that gives rise to such large events. We hunt for broken parts, fixable properties, people we can hold accountable. Our analyses of complex system breakdowns remain depressingly linear, depressingly componential - imprisoned in the space of ideas once defined by Newton and Descartes. The growth of complexity in society has outpaced our understanding of how complex systems work and fail. Our technologies have gotten ahead of our theories. We are able to build things - deep-sea oil rigs, jackscrews, collateralized debt obligations - whose properties we understand in isolation. But in competitive, regulated societies, their connections proliferate, their interactions and interdependencies multiply, their complexities mushroom. This book explores complexity theory and systems thinking to understand better how complex systems drift into failure. It studies sensitive dependence on initial conditions, unruly technology, tipping points, diversity - and finds that failure emerges opportunistically, non-randomly, from the very webs of relationships that breed success and that are supposed to protect organizations from disaster. It develops a vocabulary that allows us to harness complexity and find new ways of managing drift.

Hypnotherapy - Unlocking the...

Vivian Westlake

Hypnotherapy is a therapeutic technique that uses the power of hypnosis to bring about positive change in a person's thoughts, behaviors, and emotions. It is a natural, relaxed state of heightened awareness and focus, during which individuals are more open to suggestions and capable of accessing the subconscious mind. While hypnosis is often associated with entertainment or mysticism, hypnotherapy is a well-established and evidence-based practice used by licensed professionals to address a wide variety of issues, from stress and anxiety to chronic pain and bad habits.
The origins of hypnotherapy can be traced back thousands of years to ancient cultures, where the use of trance-like states was employed for healing and spiritual rituals. In more modern times, figures such as Franz Anton Mesmer and Milton Erickson helped shape the practice, bringing hypnosis into the medical field. Today, hypnotherapy is recognized as a legitimate treatment in many parts of the world, with practitioners working alongside other healthcare professionals to improve mental and physical well-being.
One of the core principles of hypnotherapy is that the subconscious mind plays a significant role in shaping our thoughts, behaviors, and perceptions. While the conscious mind controls our daily decisions and actions, the subconscious mind holds our deeper beliefs, memories, and automatic reactions. It is in this subconscious realm where many issues, such as phobias, unresolved trauma, and limiting beliefs, are stored and continue to influence us in ways we may not be fully aware of. Hypnotherapy works by bypassing the conscious mind and speaking directly to the subconscious, allowing for deep-seated changes to take place.

Industrial Designs - Ideas and...

Phil Gilberts

Industrial design plays a pivotal role in modern industry by significantly influencing product functionality, aesthetics, user experience, and market competitiveness. One of the primary contributions of industrial design is the enhancement of product functionality and usability. Designers achieve this by thoroughly understanding user needs and behaviors, which allows them to create products that are intuitive and easy to use. This not only boosts customer satisfaction but also reduces the demand for customer support. 
  
The aesthetic appeal and brand identity of a product are also heavily shaped by industrial design. A well-designed product can greatly enhance a brand’s image and market position, as the integration of form and function results in visually appealing products that stand out. This visual attractiveness is a critical factor in consumer decision-making and fostering brand loyalty. 
  
Innovation and differentiation are crucial in a competitive market, and industrial designers play a key role here by merging creative thinking with technical expertise. This fusion leads to the development of unique features and functionalities that distinguish products from those of competitors.

Dinner on Mars - The...

Lenore Newman, Evan D. G. Fraser

From Impossible Burgers to lab-made sushi, two witty, plugged-in food scientists explore leading-edge AgTech for the answer to feeding a settlement on Mars—and nine billion Earthlings too 
 
 
 
Feeding a Martian is one of the greatest challenges in the history of agriculture. Will a Red Planet menu involve cheese and ice cream made from vats of fermented yeast? Will medicine cabinets overflow with pharmaceuticals created from engineered barley grown using geothermal energy? Will the protein of choice feature a chicken breast grown in a lab? Weird, wonderful, and sometimes disgusting, figuring out "what's for dinner on Mars" is far from trivial. If we can figure out how to sustain ourselves on Mars, we will know how to do it on Earth too. In Dinner on Mars, authors Fraser and Newman show how setting the table off-planet will supercharge efforts to produce food sustainably here at home. 
 
 
 
For futurists, sci-fi geeks, tech nuts, business leaders, and anyone interested in the future of food, Dinner on Mars puts sustainability and adaptability on the menu in the face of our climate crisis.
