Migratory and resident hosts have been hypothesized to fulfil distinct roles in infectious disease dynamics. However, the contribution of resident and migratory hosts to wildlife infectious disease epidemiology, including that of low pathogenic avian influenza virus (LPAIV) in wild birds, has largely remained unstudied. During an autumn H3 LPAIV epizootic in free-living mallards (Anas platyrhyn...

It is particularly important for the development of agriculture to strengthen the agricultural pests monitoring, prevention and cure. The traditional methods of remote sensing (RS) for agricultural pests monitoring cannot meet the needs of agricultural development, because of their long time-consuming, high cost, and low accuracy. However, Unmanned Aerial Vehicle (UAV) remote sensing, as a new ...

Crop pests and pathogens pose a significant and growing threat to food security, but their geographical distributions are poorly understood. We present a global analysis of pest and pathogen distributions, to determine the roles of socioeconomic and biophysical factors in determining pest diversity, controlling for variation in observational capacity among countries. Known distributions of 1901...

Assessing risk from a novel pest or pathogen requires knowing which local plant species are susceptible. Empirical data on the local host range of novel pests are usually lacking, but we know that some pests are more likely to attack closely related plant species than species separated by greater evolutionary distance. We use the Global Pest and Disease Database, an internal database maintained...

The migration of developing T cells (thymocytes) between distinct thymic microenvironments is crucial for their development. Ex vivo studies of thymus tissue explants suggest two distinct migratory behaviors of thymocytes in the thymus. In the cortex, thymocytes exhibit a stochastic migration, whereas medullary thymocytes show confined migratory behavior. Thus far, it has been difficult to foll...

Migration is an important event in many animal life histories, but the degree to which individual animals participate in seasonal migrations often varies within populations. The powerful ecological and evolutionary consequences of such partial migration are now well documented, but the underlying mechanisms are still heavily debated. One potential mechanism of partial migration is between-indiv...

Wood packaging represents a pathway for the introduction and spread of pests. In March 2002, the Food and Agriculture Organization (F.A.O.) issued some regulations describing globally approved phytosanitary measures that significantly reduce the risk provoked by most of pests. The main purpose of this work is to describe the disinfesting system of pallets through the microwaves treatment.
