Abstract:
This study investigated the effects of a seasonally variable forage resource on herbivore population dynamics. This involved estimating the relative importance of environmental conditions, and the accessible and used forage resources, at different stages of the seasonal cycle to herbivores in different life-stages and at different points in the reproductive cycle. This study was carried out in the Richtersveld region in South Africa, using goats kept by semi-nomadic Nama pastoralists. In the main study site, the Richtersveld National Park (RNP), herd movements follow a general seasonal migrato

The Central Asian (CA) rangelands is a part of the arid and semi-arid ecological zones and spatial extent of drylands in CA (Tajikistan, Kazakhstan, Uzbekistan, Kyrgyzstan, and Turkmenistan) is vast.

Abstract:
Mining in arid regions of Australia is followed by restoration and rehabilitation efforts. However, attempts to reintroduce many woody plant species have been unsuccessful. Water is the key limiting resource to plant growth and seed germination in arid zones. In this thesis, I investigated ecophysiological processes that may help improve recruitment across novel arid landscapes. I tested seed traits and dormancy cues of eight keystone plants and found that six of them had non-dormant, rapidly germinating seeds; a trait we propose is an adaptation to the region’s unpredictable rainfall.

Abstract:
Climate change impact and drought phenomena linked with anthropogenic pressure have become a growing concern for water resource managers and policy makers, particularly in arid and semi-arid regions. This research proposes generic methodologies to evaluate the prospective impact of such changes at a basin-scale. The Lower Zab River Basin, northern Iraq, has been selected as a representative case study. These methodologies have been achieved through the following: (1) Highlight the impact of potential evapotranspiration (PET) methods, elevation, and climatic conditions on the reconnaissance dro

The movements of nomadic species are poorly understood, being highly dynamic over time and space.

To date, no standardized, large-scale monitoring has been carried out for arid zone or nomadic species. In Chapter 2, I describe a protocol for surveying this

Abstract:
This study investigates the ecology of an arid zone calcrete through an interdisciplinary design composed of multivariate analyses, hydrology, isotopic ecology and genetics. Our results indicate that the biotic community (microbes and stygofauna) is closely linked to the hydrodynamic conditions influenced by different rainfall regimes. The inflow of rainfall triggered shifts towards more deterministic dynamics, revealing a complex web of interactions. This investigation provides crucial untangling of the ecological dynamics regulating biotic communities in groundwaters.

Abstract:
Une grande part de la consommation énergétique des bâtiments en Iran provient du pétrole, du gaz et de l'électricité, alors même que les ressources en énergies fossiles s'épuisent dans le pays. De plus, la consommation énergétique moyenne y est plus importante que dans d'autres pays, y compris des pays qui disposent de ressources importantes en énergies fossiles, tandis que les subventions accordées par le gouvernement Iranien renforce encore cette tendance en rendant bon marché sur le marché intérieur les prix du pétrole et du gaz. Bâtiments et maisons représentent une part moyenne importante

La question de l’accès à l’eau potable se pose avec acuité pour les pays de la régionsubsaharienne où un individu sur trois n’a pas accès à une source d’eau améliorée.L’objectif de cette thèse vise à définir les conditions d’une gestion durable de l'eau pourla ville de Djibouti. Dans ce contexte, la question de l'approvisionnement en eau estenvisagée dans une perspective patrimoniale afin de tenir compte des particularités dela ressource en zone aride et des usages spécifiques qui lui sont associés dans unenvironnement marqué par la pauvreté. Un apport majeur de la thèse réside d'une partdans

Abstract:
This thesis examines how our picture of the Epipalaeolithic of the southern Levant has been structured, what its evidential base is and how it has gained authority. Hitherto, research has focused on describing variability in microliths, the type-fossil of the period, in terms of archaeological cultures using typology. Narrative analysis was used in the first part of this thesis to explore the work of three main researchers in the field. This has shown that narrative strategies are indeed employed in archaeological texts to describe lithic and other data creating a picture of the period that re

Abstract:
How individuals respond to environmental demands and pressures from conspecifics and from other species determines whether they will survive and reproduce, and hence whether their populations will persist. However, not all environments are benign or predictable, and not all populations of the same species respond to environmental pressures in the same way. The overall objective of this thesis was to incorporate both biotic and abiotic interactions into one conceptual framework to better understand and predict how species’ populations change across space and time. To help progress this objectiv
