Messung ökologischer Effizienz mittels Data Envelopment by Katrin Allen

By Katrin Allen

Die "ökologische Effizienz" gewinnt für Unternehmungen im Rahmen eines nachhaltigen Umweltmanagements zunehmend an Bedeutung. Durch ihre Messung können Entwicklungen, Stärken und Schwachstellen in der unternehmerischen Umweltleistung aufgezeigt werden.

Katrin Allen untersucht die Möglichkeiten und Grenzen der information Envelopment research (DEA) als tool für eine Messung ökologischer Effizienz. Nach einer examine der reason und Schwierigkeiten der Messung ökologischer Effizienz stellt sie die Grundlagen der DEA anhand eines einfachen Zahlenbeispiels vor. Der Schwerpunkt liegt auf der Identifikation und examine von Erweiterungen der DEA, die für eine Messung ökologischer Effizienz erforderlich oder nützlich sind. Dazu wird insbesondere auf Erkenntnisse der Produktions- und Entscheidungstheorie zurückgegriffen.

Evolution's Wedge: Competition and the Origins of Diversity by David W. Pfennig, Karin S. Pfennig

By David W. Pfennig, Karin S. Pfennig

Evolutionary biology has lengthy sought to provide an explanation for how new qualities and new species come up. Darwin maintained that pageant is vital to figuring out this biodiversity and held that choice appearing to reduce festival reasons rivals to develop into more and more diversified, thereby selling new features and new species. regardless of Darwin’s emphasis, competition’s function in diversification continues to be debatable and principally underappreciated.

In their artificial and provocative publication, evolutionary ecologists David and Karin Pfennig discover competition's function in producing and retaining biodiversity. The authors talk about how choice can decrease source pageant or high priced reproductive interactions by means of selling trait evolution via a strategy referred to as personality displacement. They extra describe personality displacement’s underlying genetic and developmental mechanisms. The authors then give some thought to personality displacement’s myriad downstream results, starting from shaping ecological groups to selling new characteristics and new species or even fueling large-scale evolutionary developments. Drawing on a variety of experiences from traditional populations, and written for a vast viewers, Evolution’s Wedge seeks to motivate destiny learn into personality displacement’s many implications for ecology and evolution.

Convergent Evolution: Limited Forms Most Beautiful (Vienna by George McGhee

By George McGhee

Charles Darwin famously concluded at the foundation of Species with a imaginative and prescient of "endless varieties most pretty" consistently evolving. greater than one hundred fifty years later many evolutionary biologists see now not unending kinds however the comparable, or very related, varieties evolving many times in lots of self reliant species lineages. A porpoise's fishlike fins, for instance, usually are not inherited from fish ancestors yet are independently derived convergent features. during this publication, George McGhee describes the ubiquity of the phenomenon of convergent evolution and connects it on to the notion of evolutionary constraint--the concept that the variety of evolutionary pathways to be had to existence aren't never-ending, yet fairly constrained. Convergent evolution happens on all degrees, from tiny natural molecules to whole ecosystems of species. McGhee demonstrates its ubiquity in animals, either herbivore and carnivore; in crops; in ecosystems; in molecules, together with DNA, proteins, and enzymes; or even in minds, describing problem-solving habit and team habit because the items of convergence. for every species instance, he offers an abbreviated record of the key nodes in its phylogenetic type, permitting the reader to work out the evolutionary courting of a bunch of species that experience independently developed a comparable trait by way of convergent evolution. McGhee analyzes the function of useful and developmental constraints in generating convergent evolution, and considers the clinical and philosophical implications of convergent evolution for the predictability of the evolutionary approach.
