"The pediatric dentist is different": A qualitative study of young children's caregivers' experiences of oral health care in the Galapagos Islands.

Background: Little is known about factors influencing children's access to and use of oral healthcare services in the Galapagos Islands, a resource-limited setting.

Aim: We sought to understand caregivers' experiences and factors influencing their children's use of dental services on San Cristobal Island in the Galapagos Archipelago.

Design: A community-based qualitative interview study was carried out among 25 caregivers of children aged 6 months to 10 years.

Diatoms on the carapace of common snapping turtles: Luticola spp. dominate despite spatial variation in assemblages.

Filamentous algae are often visible on the carapaces of freshwater turtles and these algae are dominated by a few species with varying geographic distributions. Compared to filamentous algae, little is known about the much more speciose microalgae on turtles. Our objectives were to compare the diatom flora on a single turtle species (the common snapping turtle, Chelydra serpentina) across part of its range to examine spatial patterns and determine whether specific diatom taxa were consistently associated with turtles (as occurs in the filamentous alga Basicladia spp.
