What characterizes regions where right-wing populist parties are relatively successful? A prominent hypothesis proposed in the emerging “geography of discontent” literature claims that places “left behind” constitute a breeding ground for rise populism. We re-examine this by analyzing populism Germany. Our results suggest high vote shares associated with long-term decline region's relative welf...
Highlights Jackfruit leaf extraction was performed by percolation method using 96% ethanol solvent with flavonoid, saponin, tannin, alkaloid, and steroid terpenoid test. extract effective as a larvicide against larvae of Aedes aegypti. Abstract Background: Dengue Hemorrhagic Fever (DHF) is disease caused the dengue virus, which enters human bloodstream through bite mosquito genus. The DHF contr...
wide subject of the prevention of malaria in cantonments, limiting the remarks to the measurement of malaria, reduction of breeding places of anophelines, relapses and their prevention, and quinine prophylaxis. Malaria is, throughout our Indian Empire, the dominating cause of inefficiency in troops in both peace and war. In peace it always heads the list of diseases in both European and Indian ...
Wild birds share with humans the capacity for moving fast over large distances. During migratory movements, birds carry pathogens that can be transmitted between species at breeding, wintering, and stopover places where numerous birds of various species are concentrated. We consider the area of the Camargue (southern France) as an example to highlight how ad hoc information already available on...
Several species of snails, including Pomacea haustrum, Marisa cornuarietis and Helisoma duryi, have been identified as probable competitors and/or predators of planorbid intermediate hosts of Schistosoma. During the last few years, studies carried out in the Caribbean region have shown reductions and even disappearances of populations of Biomphalaria glabrata and B. straminea in breeding places...
Territorial behavior of the orange-tufted sunbird (Nectarinia osea Bonaparte) was studied in a suburb of Tel Aviv. Both male and female orange-tufted sunbirds occupied and guarded their territory throughout the year, but did so at different intensities in relation to season and fertility stages. When they were in the territory, both sexes spent most of their time at its center, and more so duri...

Introduction: An estimated population of 40% of Hormozgan province, southern Iran, live mainly in mountainous areas in close contact with Anopheles Fluviatilis. This specie has highly exophilic and anthropophilic behaviors and is one of major malaria vectors in the mountainous areas of Hormozgan province. This study was conducted to assess the irritability and susceptibility level of An. Fluv...
ITTLE information has been published on the breeding activities of the L Anhinga (Anhinga arzhinga) in spite of its rather common occurrence in many places in the warmer parts of the United States. The literature on behavior and life history of this species has been limited to accounts of a few isolated observations. Th e present paper reports some behavior not previously presented in the liter...
