The past and future climatic suitability of arabica coffee (Coffea arabica L.) in East Africa.
… of plant and animal species have shown that climatic changes affect species distributions. Global circulation models suggest climatic change over the next century, and predict warmer temperatures, and increasingly variable precipitation in East Africa. Whilst several studies have modelled the …

Assessing the climatic suitability of Bambara groundnut as an underutilised crop to future climate projections in Sikasso and Ségou, Mali
This study evaluates how future climatic projections will affect the suitability of bambara groundnut (Vigna subterranean(L) Verdc.), a type of underutilised crop in Sikasso and Ségou, southern Mali. This study was performed using a simulation approach, which considered the potential changes in …

The impacts of climate change on the summerfruit industry with respect to insect pest incursions
… to have an impact on species distributions and climatic suitability, potentially resulting in an increase of tropical or sub-tropical insect pest establishments in areas with temperate climates such as New Zealand. The increased risk of these exotic insect pests establishments is likely to …

Potential Effects of Climate Change on the Distribution and Migration of European Breeding Migratory Birds
… aims to investigate the potential impacts of climatic change on Afro-Palaearctic migratory birds by investigating simulated changes in breeding and non-breeding distribution. Methods: Generalised Additive Models were used to determine those climatic variables that produced the most robust …

Recursos alimentares de primatas da Mata Atlântica e um olhar sobre os maiores primatas deste bioma: mudanças climáticas, principais recursos de plantas e habitat
… second chapter, we assessed the overlap between climatically suitable areas (current and future) for Brachyteles arachnoides and B. hypoxanthus and their main food plants. Brachyteles is endemic to the Atlantic Forest, Critically Endangered, frugivorous/folivore, and depends on large and diverse …

Worldwide spatial distribution of Tuta absoluta (Lepidoptera: Gelechiidae) and its natural enemies under current and future climatic change conditions through modelling
… an eventual invasion of T. absoluta due to their climatic suitability for this pest. The increasing suitability for T. absoluta in open field in these countries will not be accompanied by an increase for some of the natural enemies. Therefore, this variation in suitability will have important …

Essays on development economics
… empirical strategy exploits variation in the geo-climatic suitability for flowers to understand how export shocks affect violence at the municipality level. I show that flower shocks lead to a differential reduction in unorganized violent crime (homicide rates) in the suitable municipalities, but …

Vector-borne Disease Risk Assessment in Times of Climate Change: The Ecology of Vectors and Pathogens
… considered to be very sensitive to changing climatic conditions. The duration of pathogen development inside the vector is also directly linked to the ambient temperature. This thesis addresses a multidisciplinary approach to improve risk assessment for vector species establishment and …

The potential impact of climate change on the genetic diversity of the endangered western leopard toad, Sclerophrys pantherina
… Much work has focused on the potential for climatic shifts to alter species' ranges, phenology, physiology, and behaviour, addressing higher level units of biodiversity from populations to biomes. However, the potential effects of climate change on the most fundamental unit of biodiversity, …

Geographic patterns of speciation in West and Central Africa: The role of rivers, mountains, and refugia
… preserved in the tropics. In addition, many climatic and geologic events overlap spatially making it difficult to tease apart their combined/confounding effects. This dissertation addresses these difficulties by filling major sampling gaps in Central Africa and by using a combination of …

Identifying, understanding, and conserving rare species
En cette époque de déclin de la biodiversité à l’échelle mondiale, les espèces rares méritent une attention particulière dans les efforts de conservation, car elles sont plus vulnérables à l'extinc-tion que les espèces communes. À la suite de l'adoption du Cadre mondial pour la biodiversité …
