Reconstructions of diet provide valuable insights into the ecology and evolutionary history of animals and humans in the fossil record, and the history of relationships between animals and humans. Reconstruction of past diets allows tracking numerous ecological and behavioural aspects through time and across diverse geographic areas, such as, but not limited to: trophic position, niche sharing and niche partitioning, past vegetation, migration patterns, ontogenetic and individual diet choices, and adaptations to changing environment. It also is a useful tool to track climatic change. More broadly, these insights are key to reconstructing and understanding the structure, composition, and function of past ecosystems. Multiple approaches have been proposed to infer paleodiets, including the integration of multiple proxy approaches.

Release Date: 2020-12-11
The book explores the fundamental principles, advances in forensic techniques, and its application on forensic DNA analysis. The book is divided into three modules; the first module provides the historical prospect of forensic DNA typing and introduces fundamentals of forensic DNA typing, methodology, and technical advancements, application of STRs, and DNA databases for forensic DNA profile analysis. Module 2 examines the problems and challenges encountered in extracting DNA and generating DNA profiles. It provides information on the methods and the best practices for DNA isolation from forensic biological samples and human remains like ancient DNA, DNA typing of skeletal remains and disaster victim identification, the importance of DNA typing in human trafficking, and various problems associated with capillary electrophoresis. Module 3 emphasizes various technologies that are based on SNPs, STRs namely Y-STR, X-STR, mitochondrial DNA profiling in forensic science. Module 4 explores the application of non-human forensic DNA typing of domestic animals, wildlife forensics, plant DNA fingerprinting, and microbial forensics. The last module discusses new areas and alternative methods in forensic DNA typing, including Next-Generation Sequencing, and its utility in forensic science, oral microbes, and forensic DNA phenotyping. Given its scope, the book is a useful resource in the field of DNA fingerprinting for scientists, forensic experts, and students at the postgraduate level.
