Book Description
Although feeding is not yet been thoroughly studied in many vertebrates taxa, and different conceptual and methodological approaches of the concerned scientists make a synthesis difficult, the aim of the editors is to provide a comprehensive overview of the feeding design in aquatic and terrestrial vertebrates with a detailed description of its functional properties. The book emphasizes the constant interaction between function and form, behaviour and morphology in the course of evolution of the feeding apparatus and way of feeding both complementary and basically related to survival interspecific competition, adaptation to environmental changes and adaptive radiations. Special stress is drawn onquantification of the observational and experimental data on the morphology and biomechanics of the feeding design and its element jaws, teeth, hyoidean apparatus, tongue, in order to allow present and further comparisons in an evolutionary perspective.

Book Description
A detailed, quantitative examination of the musculoskeletal biomechanics was performed to elucidate how these animals are capable of generating disproportionately high bite forces throughout ontogeny. Mechanical levers, muscle masses, and muscle architecture (fiber lengths and pennation angles) were measured from an ontogenetic series of 30 S. minor. With these data, a biomechanical model of the feeding apparatus was developed that accurately predicts individual and ontogenetic scaling of bite forces. Increasing muscle masses and changing the muscle architecture resulted in an increase in total physiological cross-sectional area (PCSA) of the jaw adductor muscles that was proportional to changes in bite-force generation. These results indicate that the disproportionate increase in bite-force generation relative to skull length found in S. minor is explained by allometric changes in muscle size and architecture that collectively act to allometrically elevate the PCSA and muscle force.

Book Description
This book provides students and researchers with reviews of biological questions related to the evolution of feeding by vertebrates in aquatic and terrestrial environments. Based on recent technical developments and novel conceptual approaches, the book covers functional questions on trophic behavior in nearly all vertebrate groups including jawless fishes. The book describes mechanisms and theories for understanding the relationships between feeding structure and feeding behavior. Finally, the book demonstrates the importance of adopting an integrative approach to the trophic system in order to understand evolutionary mechanisms across the biodiversity of vertebrates.

Book Description
The loggerhead shrike (Lanius ludovicianus) is a robin-sized bird that hunts like a small hawk, preying on insects and small animals, including small birds. This document presents a description of the species and provides information on habitat and habits, range, feeding, breeding, and conservation measures.
