| rotavirus infections in galapagos sea lions. | group a rotaviruses infect and cause diarrhea in the young of a broad range of terrestrial mammals, but it is unknown, to our knowledge, whether they infect marine mammals. during february and march of 2002 and 2003, we collected 125 serum samples and 18 rectal swab samples from galapagos sea lion pups (gsl, zalophus wollebaeki), and 22 serum samples from galapagos fur seal pups (gfs, arctocephalus galapagoensis) from nine islands of the galapagos archipelago, ecuador. sera were tested for antib ... | 2009 | 19617482 |
| same size--same niche? foraging niche separation between sympatric juvenile galapagos sea lions and adult galapagos fur seals. | 1. in vertebrates, patterns of resource utilization change throughout development according to age- and or size-specific abilities and requirements. thus, interspecific competition affects different age classes differently. 2. adults of sympatric species often show distinct foraging niche segregation, but juvenile resource use might overlap with adult competitors of similar body size. resultant negative effects on juveniles can have important consequences for population dynamics, yet such intera ... | 2013 | 23351022 |
