| molecular data reveal high diversity of uvulifer (trematoda: diplostomidae) in middle america, with the description of a new species. | members of the genus uvulifer are distributed worldwide and infect aquatic snails and freshwater fishes as first and second intermediate hosts, respectively, and fish-eating birds (kingfishers) as definitive hosts. metacercariae of uvulifer spp. were collected from the fins and skin of 20 species of freshwater fishes in mexico, guatemala, honduras, nicaragua and costa rica, and the adults were recovered from the intestine of kingfishers in four localities of mexico. the genetic divergence among ... | 2017 | 29017625 |
| karyotype description and comparative analysis in ringed kingfisher and green kingfisher (coraciiformes, alcedinidae). | kingfishers comprise about 115 species of the family alcedinidae, and are an interesting group for cytogenetic studies, for they are among birds with most heterogeneous karyotypes. however, cytogenetics knowledge in kingfishers is extremely limited. thus, the aim of this study was to describe the karyotype structure of the ringed kingfisher (megaceryle torquata linnaeus, 1766) and green kingfisher (chloroceryle americana gmelin, 1788) and also compare them with related species in order to identi ... | 2018 | 29780444 |
