The effects of patch size and isolation on metapopulation dynamics have received wide empirical support and theoretical formalization. By contrast, the effects of patch quality seem largely underinvestigated, partly due to technical difficulties in properly assessing quality. Here we combine habitat-quality modeling with four years of demographic monitoring in a metapopulation of greater white-...
In the Supplementary Information originally published with this Article, there was a typographical error in Table S1: 'CO 3 – ' now reads 'CO 3 2– '. This error has been corrected in the Supplementary Information that now accompanies the Article. In addition, a proof of the Article was inadvertently published as Supplementary Information. This has now been removed. This work is licensed under a...

Edwardsiella tarda was isolated from patients, water tortoises (Clemmys caspica), and samples of water from Lake Kinnereth, the river Jordan, well water, and sewage water. Of the 53 isolates, 35 belonged to completely identified serotypes, among them 7 new ones. Fourteen cultures had O antigens, and one had an H antigen, different from those previously described. Three serotypes isolated from p...
Thousands of Caspian seals (Phoca caspica) died in the Caspian Sea from April to August 2000. Lesions characteristic of morbillivirus infection were found in tissue specimens from dead seals. Canine distemper virus infection was identified by serologic examination, reverse transcriptase- polymerase chain reaction, and sequencing of selected P gene fragments. These results implicate canine diste...
This concern also applies to filter components and housings. Pall recognizes the importance of proper material selection, cleanliness standards, housing surface preparation, and specialized manufacturing processes with regard to product quality. Our knowledge allowed us to introduce practices that have become industry standards. All Pall Gaskleen filter assemblies are packaged in special double...

Rise in temperature is not observed in visna or maedi. The animals seem to be remarkably alert and the appetite remains unaffected throughout. The period between inoculation of infective visna material and the development of clinical signs varies from animal to animal even with a standard dose. Usually this period is very long and several months to several years may elapse before clinical signs...
