The actor Alec Baldwin, below, set a record on Saturday as the most frequent host of "Saturday Night Live," returning for a 16th time and, in doing so, breaking a tie with Steve Martin.
Alternatively, males might prefer the hue of the perianth of O. heldreichii flowers compared to that of O. dictynnae because it more closely resembles the flower colour of the females' most frequent host plants (e.g. Vicia cracca and Salvia fructicosa, see Spaethe et al. 2007 for spectral reflectance curves).
The white-tailed deer and white-footed mouse are the tick's most frequent hosts, but it also feeds on birds, dogs and other rodents, including squirrels.
Late recovery (category 3) was the most frequent host-virus interaction phenomenon observed in this test panel, and was seen for all virus isolates tested.
Although there were 16 total plant species with haustoria connections, E. castrense and N. leucocephala were found to be the most frequent hosts of C. howelliana.
Cuscuta howelliana occurred in the centre and transition zones of vernal pools, and vernal pool endemics tended to be targeted: E. castrense and N. leucocephala were found to be the most frequent hosts.
Specialization of parasites exploiting particular hosts invariably provokes disadvantages when parasitizing other hosts, and, consequently, the evolution of specialization can be seen as a compromise between the use of the maximum number of suitable hosts, and the use of the most frequent suitable host encountered [ 4].
Maddow, who used Hayes as her most frequent guest host, says that he is a much better interviewer than she is; his eagerness to ask questions sometimes camouflages the truth that, more than most of his peers, he is interested in the answers.
Indeed, we were able to demonstrate that the GyrA position 87G allele (that we find here to be the most frequent within hosts) carries a growth advantage in starved E. coli microcolonies (Katz and Hershberg 2013).
Carriage of certain MGEs in CC398 was most frequent in one host than another, but intriguingly, these patterns were country specific.
To the Editor: The nematode Angiostrongylus cantonensis (rat lung worm), a zoonotic parasite that can accidentally infect humans and cause eosinophilic meningoencephalitis, has the Norway rat (Rattus norvegicus) as one of its most frequent definitive vertebrate hosts (1 ).
