Using a geographic information system (GIS), the relations between georeferenced data set of Culex pipiens s.l. collected in Portugal mainland during seven years (2006-2012) and meteorological physiographic parameters are evaluated. This work is one results long-term surveillance program pernicious insects that act as vectors various diseases; its focus on possibility prevention can be achieved...

Sea surface temperature (SST) derived from the weekly measurements made by the Advanced Very High Resolution Radiometers (AVHRR) of NOAA satellites was used to investigate the structure and space-time variability of large-scale fronts in the Southern Indian Ocean (30–60jS and 20–150jE) during the period of 1997–1999. Monthly SST gradient maps provided an overall view of five basic fronts: the N...

We examined the distribution of ground-flora species (herbaceous and woody species <1 m tall) across riparian areas of northeastern Wisconsin in an effort to understand how hierarchical landscape properties, such as the physiographic system (ground moraine and outwash plain), valley system (constrained and unconstrained), and valley floor landforms influence distribution patterns of ground-flor...
