    Description: In the spring of 1995, during works for the rehabilitation of a wall that closed the grotto of the Old Cemetery in the Sicilian village of Alia, the skeletal remains of the victims of the cholera outbreak of 1837 that had been rapidly interred here were brought to light. From that moment on, the Alia project was developed without interruption, analysing the biological evolution of the local population by exploiting study methods characteristic of different anthropological disciplines, such as skeletal biology, population genetics and biodemography. The book renders account of research completed and in progress carried out by academics from the Universities of Florence, Palermo, Parma, Cagliari, Turin and Göttingen.
    Description: Nella primavera del 1995, durante i lavori di risanamento al muro che chiudeva la grotta del Cimitero Vecchio del paese siciliano di Alia, erano tornati alla luce i resti scheletrici delle vittime dell'epidemia di colera del 1837, qui frettolosamente inumati. Da quel momento il progetto Alia si è sviluppato senza sosta, analizzando l'evoluzione biologica della popolazione aliese mediante le metodologie di studio tipiche di differenti discipline antropologiche quali la biologia scheletrica, la genetica di popolazione, la biodemografia. Il volume dà conto delle ricerche condotte e in corso da parte di studiosi delle Università di Firenze, Palermo, Parma, Cagliari, Torino e Göttingen.

    Description: Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

    Description: Olfaction and taste are of critical importance to insects and other animals, since vital behaviours, including mate, food and host seeking, as well as predator and toxin avoidance, are guided by chemosensory cues. Mate and habitat choice are to a large extent determined by chemical signals, and chemoreceptors contribute accordingly to pre-mating isolation barriers and speciation. In addition to fundamental physiological, ecological and evolutionary consideration, the knowledge of insect taste and especially olfaction is also of great importance to human economies, since it facilitates a more informed approach to the management of insect pests of agricultural crops and forests, and insect vectors of disease. Chemoreceptors, which bind to external chemical signals and then transform and send the sensory information to the brain, are at the core of the peripheral olfactory and gustatory system and have thus been the focus of recent research in chemical ecology. Specifically, emphasis has been placed on functional characterization of olfactory receptor genes, which are derived from three large gene families, namely the odorant receptors, gustatory receptors and ionotropic receptors. Spatial expression patterns of olfactory receptors in diverse chemosensory tissues provide information on divergent functions, with regards to ecologically relevant behaviours. On the other hand, characterization of olfactory receptor activation profiles, or “deorphanization”, provides complimentary data on the molecular range of receptivity to the fundamental unit of the olfactory sense. The aim of this Research Topic is to give an update on the breadth and depth of research currently in progress related to understanding the molecular mechanisms of insect chemoreception, with specific emphasis on the olfactory receptors.

    Description: The great diversity of land plants (especially angiosperms) is mainly reflected in the diversity of various reproductive organs of plants. However, despite long time intensive investigations, there are still uncertainties and sometimes misunderstandings over the nature and evolution of reproductive organs in land plants. With the new advances made in various fields of botany (especially at molecular level), there is increasing light shed on some aspects of flowers (reproductive organs of angiosperms). In this ebook, we collect 15 papers reporting new understanding on plant reproductive organs. These works range from morphology and anatomy to molecular regulatory networks underlying traditional observations. We understand this single book cannot reach our goal, but we do hope that this book can contribute to or initiate some efforts leading to the final solution of some problems concerning the homology and evolution of reproductive organs in plants.

    Description: Vibrios are Gram-negative bacilli that occur naturally in marine, estuarine, and freshwater systems. Some species include human and animal pathogens capable of causing gastroenteritis, wound infections, cholera, and fatal septicemia. Over the past decades, cutting edge research on Vibrio genomics has promoted a tremendous advance in our knowledge of these pathogens. Significant developments include the discovery of emerging epidemic clones, tracking the spread of new strain variants, and an intensified appreciation of the role of mobile genetic elements in antibiotic resistance spread as well as pathogenesis. Furthermore, improved understanding of the interaction of Vibrios with a variety of living organisms in the aquatic environment has documented the significant role of environmental reservoirs in their seasonal cycle favoring persistence of the pathogen during inter-epidemic periods and enhancing disease transmission. This Research Topic is dedicated to our current understanding in these areas and will bring together leading experts in the field to provide a deep overview of Vibrios ecology and evolution, and will suggest the pathway of future research in this field.

    Description: Since Hans Selye's seminal work in the 1930s, there have been numerous advances with respect to our understanding of how the nervous and endocrine systems interact to help animals cope with stressors and how chronic stress may adversely impact health. Our modern understanding of stress essentially began in 1954 with the race to discover the hypothalamic releasing factor controlling ACTH secretion and mediating the endocrine response to stressors. Since the isolation of corticotropin releasing factor (CRF) in 1981, interest in CRF has focused not only on its hypophysiotropic function, but also its much broader role in coordinating many of the endocrine, behavioral and autonomic nervous system changes that occur during stress. The goal of this Research Topic is to solicit reviews and general research articles highlighting new research into stress and the hypothalamus-pituitary-adrenal (HPA) axis in the following areas: HPA axis interaction with energy regulating mechanisms during stress; and new studies on the role of CRF and urocortin and urocortins 2 and 3 in behavioral adaptation to stressors.

    Description: Alterations in gene expression are essential during growth and development phases and when plants are exposed to environmental challenges. Stress conditions induce gene expression modifications, which are associated with changes in the biochemical and physiological processes that help plants to avoid or reduce potential damage resulting from these stresses.After exposure to stress, surviving plants tend to flower earlier than normal and therefore transfer the accumulated epigenetic information to their progenies, given that seeds, where this information is stored, are formed at a later stage of plant development.DNA methylation is correlated with expression repression. Likewise, miRNA produced in the cell can reduce the transcript abundance or even prevent translation of mRNA. However, histone modulation, such as histone acetylation, methylation, and ubiquitination, can show distinct effects on gene expression. These alterations can be inherited, especially if the plants are consistently exposed to a particular environmental stress. Retrotransposons and retroviruses are foreign movable DNA elements that play an important role in plant evolution. Recent studies have shown that epigenetic alterations control the movement and the expression of genes harbored within these elements. These epigenetic modifications have an impact on the morphology, and biotic and abiotic tolerance in the subsequent generations because they can be inherited through the transgenerational memory in plants. Therefore, epigenetic modifications, including DNA methylation, histone modifications, and small RNA interference, serve not only to alter gene expression but also may enhance the evolutionary process in eukaryotes.In this E-book, original research and review articles that cover issues related to the role of DNA methylation, histone modifications, and small RNA in plant transgenerational epigenetic memory were published.The knowledge published on this topic may add new insight on the involvement of epigenetic factors in natural selection and environmental adaptation. This information may also help to generate a modeling system to study the epigenetic role in evolution.
