| schulzia chiribita n. sp. (nematoda, trichostrongylina, molineoidea) parasite of leptodactylus rhodonotus (amphibian) from peru. | a third species of the genus schulzia travassos, 1937 a parasite of leptodactylus rhodonotus (amphibian, leptodactylidae) originating from peru is described. by the pattern of the caudal bursa, the specimens are closely related to the two other species. they are distinguished from schulzia uzu lent & santos, 1989, parasite from atelopus oxyrhynchus in venezuela, by the shape of the ovejector and from schulzia travassosi durette-desset, baker & vaucher, 1985, parasite from bufo crucifer in brasil ... | 2000 | 10743644 |
| further data on sesamoid identity from two anuran species. | considering that the identification of equivalent entities is the basis for any comparative analysis, we compare the histology, histochemistry, shape and dimensions of epiphyses, carpal and sesamoids in two anuran frogs. our goal was to explore the morphological correspondence among these three skeletal elements in order to clarify the sesamoid identity. we studied the skeletogenesis, contour geometric morphometry and dimensions of forelimb elements of juveniles of two anurans species leptodacty ... | 2015 | 25810404 |
| first report of schulzia travassosi (nematoda, trichostrongylina, molineoidea) for amphibians of the chaco region in argentina and proposal of oswaldocruzia melanostictusi nov. comb. | this is the first record of the nematode parasite schulzia travassosi (trichostrongylina, molineidae) in two argentinean amphibians, leptodactylus bufonius and rhinella major, collected in two localities of the chaco region, las lomitas (formosa province) and taco pozo (chaco province). the species was observed using light and scanning electron microscopy (sem) and compared with previous studies of paraguayan specimens. regarding metric characters, the measurements found in argentinean specimens ... | 2015 | 26408605 |
| checklist of nematode parasites of amphibians from argentina. | this review includes information about 47 taxa of nematode parasites reported from 34 species of argentinean amphibians, all belonging to order anura (33 native species and 1 introduced species). thirty four nematode species have been reported as adults and 13 species were reported as larvae (10 taxa) or juveniles (3 taxa). two species, cosmocerca parva and c. podicipinus (cosmocercidae), collected as adults, are the most commonly occurring adult nematodes in argentinean amphibians; each of them ... | 2015 | 26249967 |
| biodiversity of trematodes associated with amphibians from a variety of habitats in corrientes province, argentina. | the main goals of this study were to compare the richness of parasitic trematodes in amphibians with diverse habits (terrestrial, fossorial, semi-aquatic and arboreal), and to evaluate whether the composition of the trematode community is determined by ecological relationships. specimens were collected between april 2001 and december 2006 from a common area (30 ha) in corrientes province, argentina. trematodes of amphibians in this area comprised a total of 19 species, and were dominated by comm ... | 2013 | 22874101 |
| contrasting life-histories in two syntopic amphibians of the leptodactylus fuscus group (heyer 1978). | we used skeletochronology to compare age, size, reproductive parameters and growth patterns of two related, anuran amphibians from northern argentina: leptodactylus bufonius (n=69) and l. latinasus (n=56), in order to better understand their coexistence in syntopy. previous studies showed that the two species overlap in their dietary requirements and utilize the same habitats for feeding and breeding. we found that their life-history patterns are significantly different, l. bufonius being larger ... | 2019 | 31365650 |
