A total of 475,431 mosquitoes representing 8 genera and 43 species were collected from a marsh in the western Kenya highlands to determine species composition and succession in relation to the epidemiology of Rift Valley fever virus. Culex pipiens was the most common species, totalling 92.3% of the collection, followed by Cx. zombaensis (2.2%), Anopheles coustani (1.1%), An. squamosus (0.8%), M...

Sixteen monthly visits were made to the Ndumu game reserve when resting Aedes circumluteolus mosquitoes were collected on the ground. The population density reached exceedingly high levels 7 or more days after the Usutu and/or Pongola rivers inundated their flood plains, and was related mainly to river flooding and far less to local rainfall. During dry months male Ae. circumluteolus disappeare...

Iso-Wetlands is a new, NERC-funded collaborative research project involving researchers at UCL Institute of Archaeology, the University Leeds and UK Centre for Ecology Hydrology. The developing sulfur isotope analysis archaeological plants animals as new tool exploring hydrological conditions under which agricultural production was taking place. This development has potential to improve underst...

Abstract. Isotope mass balance models have undergone significant developments in the last decade, demonstrating their utility for assessing spatial and temporal variability hydrological processes revealing value baseline assessment remote and/or flood-affected settings where direct measurement of surface water fluxes to lakes (i.e. stream gauging) are difficult perform. In this study, we demons...

In the conditions of increasing industrial load especially in combination with arid climate, negative geodynamic processes develop on Earth, including depletion and pollution water resources. More than 1.5 billion people suffer from lack resources natural waters. For more two thousand years, planet have been solving management problems by building reservoirs simplest structures. However, constr...
