The influence of Pleistocene climatic cycles on Southern Hemisphere biotas is not yet well understood. Australia's eastern coastal margin provides an ideal setting for examining the relative influence of landscape development, sea level fluctuation, and cyclic climatic aridity on the evolution of freshwater biodiversity. We examined the impact of climatic oscillations and physical biogeographic...
Enemy release and biotic resistance are competing, but not mutually exclusive, hypotheses addressing the success or failure of non-native plants entering a new region. Enemy release predicts that exotic plants become invasive by escaping their co-adapted herbivores and by being unrecognized or unpalatable to native herbivores that have not been selected to consume them. In contrast, biotic resi...
extended abstract 1. introduction temperature leaves undeniable effects on human activities and natural processes. the analysis of average maximum temperature and the highest temperatures related to the heat wave phenomenon is of great importance. the most important goals of this study include the investigation of the geographical distribution of the maximum average temperatures and extreme tem...
Corridor disease, transmitted by the brown ear tick (Rhipicephalus appendiculatus), is one of Africa's most pathogenic tick-borne diseases for cattle. With a focus on this species, we investigated the community parameters (richness, diversity and abundance) of ticks in the Eastern Cape, South Africa, and how this may be linked to the increasing wildlife/cattle interface in the region. There wer...
Drawing on the stylized facts and evidences, in a computable general equilibrium (CGE) model, this paper examines the impact on TFP of North–South, North–North trade-related triangular R&D spillovers. By constructing different technology appropriation parameters based on embodied and disembodied R&D, absorption and learning effects, it shows: (i) North–South R&D flows have a positive impact on ...
Transport networks play a crucial part in the global economy, with roads and railways being of particular importance at regional and national scales. However, roads and railways are founded on earthworks such as embankments, which can be susceptible to slope failure. Slope instability is a costly problem, which can lead to travel disruption, and injury or loss of life. Earthwork stability asses...
BACKGROUND High early mortality in patients with HIV-1 starting antiretroviral therapy (ART) in sub-Saharan Africa, compared to Europe and North America, is well documented. Longer-term comparisons between settings have been limited by poor ascertainment of mortality in high burden African settings. This study aimed to compare mortality up to four years on ART between South Africa, Europe, and ...
Public Bicycle-Sharing Systems (PBSS), also known as self-service public bicycle systems, are available in numerous big cities in the world (Vélib' in Paris, Bicing in Barcelona, Call-aBicycle in Munich, OyBicycle in London, etc.). Since its inception, Bicycle-sharing programs have grown worldwide. There are now programs in Europe, North America, South America, Asia, and Australia. A still grow...
This chapter is an empirical attempt to identify the nature and regional dimension of port-city relationships on a world scale. Although general processes of such relationships can be identified in the literature, regional variations are still not well understood when dealing with the insertion of port cities in the global transport chain. An analysis of a world sample is proposed using simple ...
