The circulating renin–angiotensin system (RAS) is well known for its systemic role in the regulation of blood pressure, renal hemodynamics and fluid homeostasis. However, in mammals several organs also contain a local RAS, including male and female reproductive tissues. In the present study we analysed serum from a free-living population of red deer (Cervus elaphus hispanicus) and fallow deer (Dama dama) to determine the activity of four RAS-regulating aminopeptidases (aminopeptidase A, aspartyl aminopeptidase, aminopeptidase N and aminopeptidase B) as part of a study of annual cycles of growth and condition. Our aim was to detect seasonal variations in the activities of these aminopeptidases and their relationship to the reproductive behaviour of both species in a Mediterranean environment. In both males and females there was a maximum peak of activity in autumn. A second peak was detected in spring for males while in females activity was also higher in summer. These changes may be related to a different endocrine status according to their seasonal cycle, the decreased photoperiod in autumn and the normal timing of the seasonal growth cycle. Thus, changes in the activity of RAS-regulating aminopeptidases could reflect the functional role of angiotensins through the annual cycle of both species, also suggesting an important role of these peptide hormones in the regulation of these biological processes.

Abstract Spatial and temporal occurrence can mediate behavioural interactions between apex predators, mesocarnivores and herbivores. Predators should adapt their activity to that of prey, whereas predator avoidance would be expected to influence activity patterns and space use of prey and smaller competitors. We evaluated interspecific spatiotemporal relationships in a prey-rich community including an apex predator (the wolf), three wild ungulates and several smaller herbivores/mesocarnivores, through camera trapping. All considered species (i.e. wolves and potential prey/smaller competitors: wild boar, fallow deer, roe deer, crested porcupine, red fox and European badger) were active especially at night and/or twilight. Among wild ungulates, the wolf showed the greatest temporal overlap with the wild boar and the lowest one with the least abundant and used of them, i.e. the roe deer. The main prey (i.e. the fallow deer) showed more diurnal activity and a lower temporal overlap with the predator in sites with high wolf activity than in low-activity ones. Among mesocarnivores, the red fox showed extensive temporal overlap with the wolf: the overlap between the two canids was greater in sites intensively used by this apex predator than in sites with low wolf activity, supporting a concurrent study which suggested a potential for facilitative—rather than competitive—interactions. Spatiotemporal relationships suggest complex interactions between the apex predator, prey and smaller carnivores, for which a substantial temporal or spatial association was often supported. Significance statement There is a growing interest in the influence of apex predators on ecosystems through their effects on the behaviour of prey and smaller carnivores, especially in the light of the ongoing recovery of large carnivores in temperate areas. Predators should synchronise their activity to that of prey; conversely, prey and smaller carnivores would be expected to avoid predators. In a rich community including the wolf, three wild ungulates and several mesomammals, we detected (i) a substantial temporal overlap between wolves and wild boar, porcupines and mesocarnivores; (ii) a negative temporal association between the predator and its main prey (i.e. the fallow deer) and (iii) a great temporal overlap between the wolf and the red fox. We provide a baseline to evaluate temporal changes of predator-prey-mesocarnivore behavioural interactions along with variations of carnivore-prey densities.

Meat authentication is currently a key topic in relation to the quality and safety of food of animal origin at all levels of production and the global distribution chain. New polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) based on digestion of PCR products with two restriction enzymes, MboII and AciI, have been developed for the specific identification of raw and heat-processed meat from red deer (Cervus elaphus), sika deer (Cervus nippon), roe deer (Capreolus capreolus), fallow deer (Dama dama), mouflon (Ovis musimon), wild boar (Sus scrofa), hare (Lepus europaeus) and cattle (Bos taurus). The PCR primers were targeted in a well-conserved region of the cytochrome b (CYTB) gene to amplify a 378 bp region of all the analysed species. This simple, rapid and cost-effective method is suitable for identification of the meat of game species and their possible substitution by beef.

The use of strontium isotope analysis to provenance biominerals such as bone and teeth has become a regularly applied component of archaeological research. This method works by comparing the isotopic composition of these materials with regional bioavailable soil values, allowing an estimation of the distance and vector of an individual’s mobility. New advances in analytical equipment has facilitated the spatially resolved micro-analysis of strontium isotope composition using laser ablation sampling, allowing intra-sample heterogeneity to be quantified. This provides the opportunity to determine not only the overall provenance of a material, but also the degree of mobility during biomineral formation.This research applies laser ablation multi-collector inductively coupled plasma mass spectroscopy (LA-MC-ICPMS) to 90 teeth of Lower and Middle Palaeolithic faunal prey from Lower and Middle Palaeolithic archaeological sites within Israel and France. These sites span a crucial period in human evolution, characterised by the radiation of multiple hominin species and by dynamic oscillations of climate with attendant changes in fauna and flora. The strontium isotope values from LA-MC-ICPMS analysis in this thesis show a high level of intra-sample variability, which would not have been captured by a traditional analytical methodology. This suggests that, despite some problems in obtaining accurate results due to offsets between solution and laser values, strontium isotope studies that do not utilise spatially resolved micro-analysis are unable to accurately determine mobility.The results of this research demonstrate that fauna from the archaeological sites of interest—including Amud, Qafzeh, Tabun, Skhull, Holon, Bois Roche, Le Moustier, La Chapelle-aux-Saints, Les Fieux, Pech de l’Azé II and Rescoundudou—appear to have patterns of mobility that are controled by variables such as species, marine isotope stages (MIS) and regional physiography. Specifically, Persian fallow deer, bison, mountain goat/chamois and fox are frequently mobile between different geological environments during amelogenesis while wild boar and rhinoceros are sessile. The calculated range of distance for minimum possible mobility for each sample is large, ranging from 0 km to 350 km. The median values for minimum possible mobility for each species suggest that wild boar, bison and fox are mobile over the greatest distance while Bos, rhinoceros, Persian fallow deer and unidentified deer are mobile over the least. Furthermore, fauna in MIS 4 and 3 are significantly more mobile than in MIS 6 and 5. Fauna from France are more mobile than those from Israel, which is attributed to the location of the archaeological sites adjacent to significant river systems that could serve as conduits of mobility, even during inhospitable climate periods. Overall, these insights show that strontium isotope analysis can be usefully applied to quantifying mobility on a broad temporal and geographic scale, rather than simply being used, as is typical, for locating the source of material within a specific archaeological site.
