Abstract Background Small mammals are important maintenance hosts of ectoparasites as well as reservoir hosts for many arthropod-borne pathogens. In Germany, only a few studies have investigated ectoparasite communities on small mammals in their natu

Most Bartonella spp. are transmitted by fleas and harbored by small mammals which serve as reservoirs. However, little is known about the composition of fleas and their Bartonella spp. from small mammals in Central Europe. Therefore, the aims of this

Bartonellae cause zoonotic diseases and are transmitted by arthropods. Rodents are reservoirs for most Bartonella spp. As the knowledge about Bartonella in rodents and their parasitizing ectoparasites is scarce in Germany, this study's objectives wer

Rickettsiae are emerging pathogens causing various types of spotted fever and typhus and are mostly transmitted by arthropods to humans and animals. In order to investigate the distribution of Rickettsiae of the spotted fever group (SFG) in small mam

Following Oyer (2004) and Rajgopal, Shevlin and Zamora (2006), we provide evidence that the level of stock option compensation results from outside opportunities in the managerial labor market for a sample of 3,214 CEO-year observations from S&P1500

A series of enantiomerically pure 2-[2-(diarylphosphino)aryl]-oxazolines was prepared from commercially available or synthetic amino alcohols. For oxazoline formation three procedures were employed: ( i ) one pot condensation with a 2-halobenzoic aci
