Genetic variation in the cellular response of Daphnia magna (Crustacea: Cladocera) to its bacterial parasite
Linking measures of immune function with infection, and ultimately, host and parasite fitness is a major goal in the field of ecological immunology. In this study, we tested for the presence and timing of a cellular immune response in the crustacean Daphnia magna following exposure to its sterilizing endoparasite Pasteuria ramosa. We found that D. magna possesses two cell types circulating in t...

متن کاملAn annotated checklist of the Cladocera (Crustacea: Branchiopoda) of Colombia.
Based on the revision of available literature on the Colombian Cladocera (Crustacea: Branchiopoda), we present an annotated checklist, with taxonomical comments for all taxa recorded since the start of research on this group in the country in 1913. We have listed 101 valid taxa, of which most records belong to the Caribbean region of Colombia. The situation in Colombian Cladocera taxonomy is, a...
متن کاملChromosome Number Variation in Iranian Populations of Acorus calamus
Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
متن کاملAn annotated checklist of the Cladocera (Crustacea: Branchiopoda) from India.
Based on a revision of available literature on the Indian Cladocera (Crustacea: Branchiopoda), we present an updated checklist, with taxonomical updates and comments for all taxa recorded since the start of research of this group in the country since 1860. We have listed a total of 137 valid taxa, of which most records belong to species groups that need revision worldwide. The situation in Indi...
