Project description:Modelling territorial occupancy and reproductive success is a key issue for better understanding the population dynamics of territorial species. This study aimed to investigate these ecological processes in a Eurasian Eagle-owl (Bubo bubo) population in south-eastern Spain during a seven-year period. A multi-season, multi-state modelling approach was followed to estimate the probabilities of occupancy and reproductive success in relation to previous state, time and habitat covariates, and accounting for imperfect detection. The best estimated models showed past breeding success in the territories to be the most important factor determining a high probability of reoccupation and reproductive success in the following year. In addition, alternative occupancy models suggested the positive influence of crops on the probability of territory occupation. By contrast, the best reproductive model revealed strong interannual variations in the rates of breeding success, which may be related to changes in the abundance of the European Rabbit, the main prey of the Eurasian Eagle-owl. Our models also estimated the probabilities of detecting the presence of owls in a given territory and the probability of detecting evidence of successful reproduction. Estimated detection probabilities were high throughout the breeding season, decreasing in time for unsuccessful breeders but increasing for successful breeders. The probability of detecting reproductive success increased with time, being close to one in the last survey. These results suggest that reproduction failure in the early stages of the breeding season is a determinant factor in the probability of detecting occupancy and reproductive success.

Project description:Each predator hunts and consumes its prey in a particular way. Consequently, the traces left by predators on bones might vary according to the manner in which the prey are processed. For this reason, prey size has been proposed as a key issue that affects the damage inflicted on bones. The Eagle Owl (Bubo bubo) is one of the main potential predators of small prey found in archaeological sites. However, detailed taphonomic research describing bone accumulations produced by this nocturnal raptor is still scarce. The aim of the present work is to describe a modern accumulation of pellets originated by the Eagle Owl from this perspective, with a specific focus on birds. Particular attention is paid to prey size to evaluate the real significance of this variable when assessing bone damage. The results confirm that bone alterations reflect how prey was ingested, as the bones show greater damage with increasing prey size. This finding emphasises the complexity of characterising archaeological accumulations, as the alterations will vary according to prey size. In addition, bone architecture-or other aspects that cannot be controlled-may hinder accurate diagnosis and should be taken into account.

Project description:Yersinia pestis causes bubonic plague in humans and rats. The disease is characterized by an enlarged, painful lymph node, termed a bubo, that develops following bacterial dissemination from an intradermal flea bite injection site. In susceptible animals, the bacteria quickly overcome host innate immune defenses in the lymph node, spread systemically through the blood, and produce fatal sepsis 1,2. At the terminal stage of disease, the bubo contains massive numbers of extracellular bacteria, necrotic lymphoid tissue, hemorrhage, and fibrin 2. The extreme virulence of Y. pestis has been largely ascribed to its ability to avoid innate immunity by preventing phagocytosis, selectively killing immune cells, and down regulating the proinflammatory response 3. Here we report that two innate immune effector mechanisms are generated during bubonic plague in the rat: iron limitation and nitrosative stress. The expression of nitric oxide synthase (iNOS) by rat polymorphonuclear neutrophils (PMNs) was induced in the bubo, and mutation of the Y. pestis hmp gene, which encodes a flavohemoglobin important for resistance to nitric oxide (NO), attenuated virulence. Thus, although Y. pestis avoids uptake and intracellular killing by phagocytes, it still encounters innate immune effector molecules, particularly phagocyte-derived reactive nitrogen species, in the extracellular environment of the bubo.
