“…Projected northward expansion of the geographic range of Ae. albopictus (by approximately 200-500 km) was modest using OW and OWAT (Figure 4, Additional file 1), at least in comparison to the range spread projected for other arthropod vectors with climate change [54]. (Figure 4, Additional file 1).…”

Background: Since the 1980s, populations of the Asian tiger mosquito Aedes albopictus have become established in south-eastern, eastern and central United States, extending to approximately 40°N. Ae. albopictus is a vector of a wide range of human pathogens including dengue and chikungunya viruses, which are currently emerging in the Caribbean and Central America and posing a threat to North America.

“…Such approaches are more accurate for modelling complex, weak or temporary processes like seasonal reproduction or blood feeding according to host dynamics (Randolph et al, 2002;Ogden et al, 2005Ogden et al, , 2006 and are able to deal with environmental factors other than climate or vegetation, such as anthropogenic effects, landscape uses or species competition/ exclusion (Sumilo et al, 2007). By using equations that describe the growth patterns of a tick population, the infectious status of individuals, their contact with susceptible hosts and host immunity can be easily integrated to obtain disease transmission models (Kitron & Mannelli, 1994).…”

Summary :As evidence of global changes is accumulating, scientists are challenged to detect distribution changes of vectors, reservoirs and pathogens caused by anthropogenic and/or environmental changes. Statistical and mathematical distribution models are emerging for ixodid hard ticks whereas no prediction has ever been developed for argasid ones. These last organisms remain unknown and under-reported; they differ from hard ticks by many structural, biological and ecological properties, which complicate direct adaptation of hard tick models. However, investigations on bibliographic resources concerning these ticks suggest that distribution modelling based on natural niche concept and using environmental factors especially climate is also possible, bearing in mind the scale of prediction and their specificities including their nidicolous lifestyle, an indiscriminate host feeding and a short bloodmeal duration, as well as a flexible development cycle through diapause periods. Résumé : CARACTÉRISTIQUES BIOLOGIQUES ET ÉCOLOGIQUES DES TIQUES MOLLES (IXODIDA: ARGASIDAE) ET IMPLICATIONS QUANT À LA PREDICTION DE LEUR DISTRIBUTION ET DES MALADIES ASSOCIÉES Dès lors que des preuves du changement global s'accumulent, les scientifiques se doivent de détecter les changements de distribution de vecteurs, de réservoirs et de pathogènes causés par des modifications anthropogéniques ou environnementales. Alors que des modèles de distribution statistiques ou mathématiques, commencent à émerger pour les tiques dures (ixodidés), aucune prédiction n'est disponible pour les tiques molles (argasidés). Ces organismes restent inconnus et sous-estimés ; ils diffèrent des tiques

“…Similarly, in Sweden, the distribution of ticks has moved northward (Lindgren et al, 2000). North American studies of the effects of climate change on distribution of I. scapularis focus largely on northward movement of the ticks due to sufficiently warm summer temperatures (e.g., Ogden et al, 2005Ogden et al, , 2006 or changes in precipitation (Subak, 2003;McCabe and Bunnell, 2004) which is in contrast to the European focus on autumn or winter cold.…”

Spatial Dynamics of Lyme Disease: A Review

Lyme disease (LD), the most frequently reported vector-borne disease in the United States, requires that humans, infected vector ticks, and infected hosts all occur in close spatial proximity. Understanding the spatial dynamics of LD requires an understanding of the spatial determinants of each of these organisms. We review the literature on spatial patterns and environmental correlates of human cases of LD and the vector ticks, Ixodes scapularis in the northeastern and midwestern United States and Ixodes pacificus in the western United States. The results of this review highlight a need for a more standardized and comprehensive approach to studying the spatial dynamics of the LD system. Specifically, we found that the only environmental variable consistently associated with increased LD risk and incidence was the presence of forests. However, the reasons why some forests are associated with higher risk and incidence than others are still poorly understood. We suspect that the discordance among studies is due, in part, to the rapid developments in both conceptual and technological aspects of spatial ecology hastening the obsolescence of earlier approaches. Significant progress in identifying the determinants of spatial variation in LD risk and incidence requires that: (1) existing knowledge of the biology of the individual components of each LD system is utilized in the development of spatial models;(2) spatial data are collected over longer periods of time; (3) data collection and analysis among regions are more standardized; and (4) the effect of the same environmental variables is tested at multiple spatial scales.
