Species boundaries in the Himantura uarnak species complex (Myliobatiformes: Dasyatidae).
Samples of the 'Himantura uarnak' species complex (H. leoparda, H. uarnak, H. undulata under their current definitions), mostly from the Coral Triangle, were analyzed using nuclear markers and mitochondrial DNA sequences. Genotypes at five intron loci showed four reproductively isolated clusters of individuals. The COI sequences showed four major mitochondrial lineages, each diagnostic of a clu...
متن کاملAnti-Predator Benefits of Mixed-Species Groups of Cowtail Stingrays (Pastinachus sephen) and Whiprays (Himantura uarnak) at Rest
Mixed-species grouping is a widespread phenomenon found in arachnids, fish, birds and mammals (Morse 1977; Hodge & Uetz 1992; Bshary & Noë 1997; Herzing & Johnson 1997). Three main reasons have been postulated as to why such heterospecific groups are formed: (1) to improve foraging efficiency, (2) to reduce predation and (3) by chance encounters (Waser 1984; Sakai & Kohda 1995; Noë & Bshary 199...
متن کاملThree new species of Monocotyle (Monogenea: Monocotylidae) from the stingray, Himantura uarnak (Rajiformes: Dasyatidae) from the Great Barrier Reef: phylogenetic reconstruction, systematics and emended diagnoses.
Three new species of Monocotyle were found on the gills of the coachwhip stingray, Himantura uarnak (Rajiformes: Dasyatidae) collected at Heron Island, Great Barrier Reef, Australia (23 degrees 27' S, 151 degrees 55 'E). Monocotyle helicophallus new species, Monocotyle multiparous new species and Monocotyle spiremae new species all have a single testis and are distinguished from other described...
متن کاملAscorbic Acid Biosynthesis and Brackish Water Acclimation in the Euryhaline Freshwater White-Rimmed Stingray, Himantura signifer
L-gulono-γ-lactone oxidase (Gulo) catalyzes the last step of ascorbic acid biosynthesis, which occurs in the kidney of elasmobranchs. This study aimed to clone and sequence gulonolactone oxidase (gulo) from the kidney of the euryhaline freshwater stingray, Himantura signifer, and to determine the effects of acclimation from freshwater to brackish water (salinity 20) on its renal gulo mRNA expre...
متن کاملFive new species of Acanthobothrium (Cestoda: Tetraphyllidea) from an unusual species of Himantura (Rajiformes: Dasyatidae) from northern Australia.
Five new species of Acanthobothrium van Beneden, 1850 from the spiral intestine of a specimen of an unusual species of Himantura from the Arafura Sea off northern Australia are described. Acanthobothrium oceanharvestae sp. n. is one of 26 category 1 species (sensu Ghoshroy and Caira 2001) lacking post-ovarian testes; it differs from these in total length, number of proglottids, number of testes...
