Supriatna, Asep: Natural Resource Modeling Optimal Harvesting Theory for Predator-Prey Metapopulations, LAP LAMBERT ACADEMIC PUBLISHING, Januar 2011, Besorgungstitel - vorauss. Lieferzeit 3-5 Tage. ISBN: 3843388377
This book presents some models for spatially-structured predator-prey populations. It addresses the issues of spatial structure and predator-prey interactions, and studies optimal harvesting for the populations. These issues are very important in the development of prudent management for the exploitations of natural resources. The book explores two common features of biological populations simultaneously: biological interactions and spatial structure. It includes relevant features that occur in most commercial marine populations, that is, predator-prey interactions, and takes into account the existence of the exchange of individuals between subpopulations, which is a common phenomenon in nature. The existence of this phenomenon is studied via metapopulation approach. Some mathematical models of commercially exploited populations are then developed and the question of how to harvest a predator-prey metapopulation is addressed. Optimal harvesting strategies are found using dynamic programming and Lagrange multipliers. Rules about harvesting source/sink subpopulations, more/less vulnerable prey subpopulations and more/less efficient predator subpopulations are explored.

Lundgren, Jonathan G. Relationships of Natural Enemies and Non-prey Foods, SPRINGER NETHERLANDS, November 2010, Besorgungstitel - vorauss. Lieferzeit 3-5 Tage. ISBN: 9048180953
There are very few natural enemies so maladapted as to rely on prey as their sole nutritional resource. The importance of non-prey sources of nutrition have received disproportionately less attention than prey when one considers how important non-prey foods are to the evolution and ecology of natural enemies. This book examines the intricate and diverse interactions between non-prey foods and natural enemies from both parties' perspectives, beginning at an organismal level and taking the reader on a journey that illustrates how these interactions are inextricably tied to the outcome of biological control programs targeting insects and weed seeds.

Veeranagoudar, Dheeraj; Saidapur, Srinivas: Some Studies on the Behavioral Ecology of Anuran Tadpoles Foraging, Locomotory Performance and Predator Prey Interactions among Anuran Tadpoles, VDM VERLAG DR. MÜLLER, Mai 2011, Besorgungstitel - vorauss. Lieferzeit 3-5 Tage. ISBN: 3639345703
Anuran tadpoles are favorite subjects for herpetologists because of their abundance, ease of culture, diversity, and adaptive strategies. In recent years these have served as model organisms in investigating many phenomena such as aggregation structure and function, kin recognition, prey- predator interactions, phenotypic plasticity, cannibalism, etc. The book is divided into 5 chapters. Chapter 1 deals with the ability of the tadpoles to asses the profitability of food habitats and distribute acordingly (ideal free distribution) is tested. Chapter 2 deals with mechanism of food detection. In chapter 3 whether is there a repeatability of locomotor performance during different larval stages and newly metamorphosed froglets is investigated. Chapter 4 deals with jumping ability of semiterrestrial tadpoles. Chapter 5 deals with prey-predator interactions. It attempts to elucidate prey preference, mechanism of predator/prey detection and defensive behaviors in response to the predator. This book useful for the young researchers as it gives some basic designs to carry out research on anuran tadpoles either in lab or in field.

Seit über 20 jahren bezaubert der Liedersänger Hermann Prey Musikliebhaber in aller Welt mit seiner Stimme, einer der schönsten Baritonstimmen des Jahrhunderts. Hermann Prey berichtet von seiner Jugend in den dreißiger und vierziger Jahren, von seinen Anfängen in Berlin als Unterhaltungsmusiker bis zum Durchbruch als Sieger im Nürnberger Meistersingerwettbewerb 1952. Er schildert seine ersten Opernerfahrungen in Wiesbaden und Hamburg ebenso wie die Höhepunkte seiner Laufbahn in München, Wien, Mailand und Genf, in Paris, London, Tokio, Moskau und New York. Großzügig öffnet Hermann Prey außerdem die Tore seiner Werkstatt. Mit Hilfe zahlreicher Notenbeispiele erläutert er Lieder, die ihm besonders am Herzen liegen, darunter den gesamten Zyklus >Die Winterreise< von Franz Schubert. Ein umfangreicher Bildteil gibt anschauliche Einblicke in die faszinierende Welt eines Künstlerlebens. Eine umfassende Diskographie gibt einen Überblick über Hermann Preys Schallplattenaufnahmen.
