Honey bee pathogens are spread worldwide and are strongly related to the decline of honey bee populations, which has severe implications for beekeeping, honey production and ecology. Honey bee pathogens are continuously studied by researchers with the aim to better understand the host-parasite relationship of these pathogens and the effects that they have on bee colonies. Honey bee pathogens include bacteria (i.e., Melissococcus plutonius and Paenibacillus larvae), microsporidia (i.e., Nosema apis and Nosema ceranae), fungi (i.e., Ascosphaera apis), protozoa (i.e., Lotmaria passim, Crithidia bombi and Crithidia mellificae) and viruses (i.e., ABPV, CBPV, IAPV, KBV, DWV, BQCV and SBV). All of these pathogens are able to infect other bee species; infections would have important implications for their life cycles (e.g., Osmia sp. and Bombus sp.) or cause unknown epidemiological effects for other hymenopterans. In addition, old and new invasive pests (such as Varroa destructor, Aethina tumida, Vespa velutina, etc.) necessitate more studies to define their role as possible vectors or possible sources of infection for honey bees. For these reasons, knowledge on honey bee pathogens has become a matter of public interest and is connected with the critical role of honey bee health. The aim of this Special Issue is to explore honey bee pathogens, considering any aspect in relation to host-pathogen interaction and highlighting the possible interaction and spillover with other bee species and invasive pests, through a series of research articles that focus on different aspects of pathologies.

The book starts from the observation that humans are very different from the other primates. Why are we naked? Why do we speak? Why do we walk upright? Fifty years ago, in 1960, marine biologist Sir Alister Hardy tried to answer this when he announced his so-called aquatic hypothesis: human ancestors did not live in dry savannahs as traditional anthropology assumes, but have adapted to live at the edge between land and water, gathering both terrestrial and aquatic foods. This eBook is an up-to-date collection of the views of the most important protagonists of this long-neglected theory of huma

Au cours de ses recherches sur l’histoire de l’évolution de l’Homme, l’auteur a été frappé par les écrits à connotation raciste de nombreux évolutionnistes, chercheurs qui ont consacré leurs travaux à l’étude de l’évolution de l’Homme. Aussi, le but de cet ouvrage est de répondre à la question : les évolutionnistes étaient-ils racistes ? Après avoir défini le racisme et situé le contexte dans lequel se placent les évolutionnistes (esclavage, colonisation, racisme), les écrits des évolutionnistes sont présentés. Puisque toute étude de l’évolution se réfère à Darwin, l’auteur passe en revue les évolutionnistes avant Darwin, les précurseurs de Darwin, Darwin et ses contemporains ainsi que les successeurs de Darwin. Le travail de chaque évolutionniste est présenté, son oeuvre est analysée afin d’en extraire les écrits à éventuelle connotation raciste et sexiste car beaucoup d’évolutionnistes étaient sexistes. Ainsi, le lecteur pourra répondre lui-même à la question posée. Ce livre s’adresse à tous ceux qui s’intéressent à l’histoire de l’Homme et à l’évolution, surtout huit ans après la célébration du bicentenaire de la naissance de Darwin et du 150e anniversaire de la parution de son livre princeps « De l’origine des espèces », et à tous ceux qui sont préoccupés par la montée du racisme. Cet ouvrage s’adresse aussi aux scientifiques, aux historiens, aux philosophes, aux psychologues, aux théologiens.

Our knowledge of human evolution has made particular progress recently, due to the discovery of new fossils, the use of new methods and multidisciplinary approaches. Moreover, studies on the departure from symmetry, including variations in fluctuating or directional asymmetries, have contributed to the expansion of this knowledge. This Special Issue brings together articles that deal with symmetry and human evolution. The notion of symmetry is addressed, including whether to reconstruct deformed fossil specimens, study biological variations within hominins or compare them with extant primates, address the shape of the brain or seek possible relationships between biological and behavioural data.
