Full textLa fin de l'époque du Pléistocène est une étape importante de l'histoire climatique de la Terre. En effet, c'est lors de cette période mouvementée que notre planète s'est pour une ultime fois libérée des conditions glaciales qui perduraient depuis des dizaines de millénaires, et souvent marquées par la présence d'imposante calottes glaciaires dans l'hémisphère nord. Il est bien connu que ce changement climatique fut également accompagné d'un déclin sans précédent de plusieurs espèces de grands mammifères terrestres, y compris une extermination rapide et brutale du mammouth laineux. En raison d'une diète composée en partie de végétaux provenant d'arbres prolifiques durant cette période, il y a de fortes raisons de croire que les ceux-ci auraient pu contribuer au maintien d'une faible densité forestière au sein de leur habitat. Par conséquent, leur extinction aurait contribué à une rapide émergence d'une variété de petits arbres feuillus tant en Sibérie qu'en Béringie, provoquant par la même occasion une réduction considérable de l'albédo de surface, qui à son tour aurait entrainé une augmentation globale de la température.L'objectif visé par cette étude est de quantifier l'impact potentiel qu'aurait pu avoir une extinction majeure de la mégafaune sur le climat de la Terre, par le biais d'une modification de la carte végétale menant à une hausse de la température. Afin d'examiner en détail la rétroaction de processus biogéophysiques à ce changement de température, nous employons le modèle de complexité intermédiaire de l'Université de Victoria (UVic) avec des scénarios plus ou moins réalistes, dont une catastrophe aux proportions exagérées servant à déterminer les limites de que peut offrir le modèle UVic. Parmi les cas plus terre-à-terre figurent quelques tests de sensibilité menés sur des paramètres tels que le taux de déboisement des mammouths, la grandeur de leur habitat, ainsi que l'année de leur extinction. D'autres expériences ayant été menées portent sur un étalement graduel d'un déclin des populations de mégaherbivores, ainsi qu'une simulation laissant libre cours aux échanges de carbone entre l'atmosphère et les autres constituants du système climatique, en autres mots une libre variation du niveau de CO2 dans l'atmosphère.En général, nous obtenons des résultats qui se conforment assez bien avec ceux d'études similaires. Dans le cas d'un scénario catastrophique, nous enregistrons une baisse de l'albédo terrestre équivalent à un peu moins de 0.006, donnant lieu à une hausse de la température se chiffrant à 0.175°C globalement. Quant aux expériences plus réalistes, les résultats en très grande majorité confirment notre intuition.

Full textThe extinction of large terrestrial mammals during the late Pleistocene (between 50 and 11 kyrs ago) is one of the most debated topics in ecology. Most studies on the causes of Pleistocene extinctions focus on the role of external factors such as climate changes and the arrival of humans. Nevertheless, the way an ecological community responds to perturbations depends on its properties, such as its number of species, species composition and the way these species interact. This thesis encloses studies with the final objective of understanding how ecological interactions between Pleistocene large mammals were organized and the potential role of such interactions in the Pleistocene extinction episode. First, I adapted food-web models to reproduce networks depicting different types of ecological interactions between consumers and resources. Then, I used these models to reconstruct predator-prey interaction networks between Pleistocene large mammals and examined the structural and dynamic properties of these systems. Finally, as an overview of the ecological impacts of Pleistocene extinctions, I discuss one of the possible consequences of the demise of Pleistocene large mammals: the loss of seed-dispersal services. The results presented here show that (i) different types of interaction networks between consumers and resources share structural properties and can be reproduced by food-web models; (ii) interactions between Pleistocene large mammals were most likely structured in a similar way to modern large-mammals assemblages in Africa, but the former were especially vulnerable to the changes in structure and dynamics caused by a newly arriving predator such as humans; (iii) among the consequences of Pleistocene extinctions is the reconfiguration of other types of interaction networks such as seed-dispersal networks. Taken together these findings emphasize how important it is to consider the role of ecological interactions in modulating the effects of perturbations when studying extinctions events

Full textThe drivers of the Australia-wide megafaunal extinction during the late Pleistocene remains poorly resolved. Hypotheses include individual or synergistic combinations of climate fluctuations, human impacts through hunting or habitat alteration by landscape burning. Moreover, the relationship between extinction dynamics and long term glacial - interglacial timescales is not yet understood. Using a series of complementary geochronology, palaeoecological and geochemical techniques on a sedimentary sequence in Alexandra Cave, Naracoorte, this study provides improved reconstructions of past climates in south-east South Australia around the time of megafaunal extinction. Ten luminescence dating samples constrain the age of the sedimentary sequence to 17.7 – 106.3 ka. Palaeoenvironmental reconstructions undertaken using charcoal, carbon isotopes and geochemical analysis reveal high fire frequency and precipitation during Marine Isotope Stage (MIS) 5, while MIS 4 and the Last Glacial Maximum were arid, with low fire frequency. MIS 3 was wet, with little fluctuation in the environment, with the exception of a change in biomass burning at 36 – 50 ka. These findings suggest that climate change likely played a minor role in the demise of megafauna locally, whereas changes in fire regime could have acted as a more significant driver or consequence of megafauna extinction.
