| reptiles and amphibians as potential reservoir hosts of chikungunya virus. | chikungunya virus is an emerging arbovirus of significant human-health concern. little is known about its sylvatic cycle, including whether ectothermic vertebrates are permissive to infection. in this study, individuals from ten species of reptiles and amphibians were inoculated with chikungunya virus and samples of blood were tested to characterize viremia and seroconversion. viremia was not detected in cane toads, house geckos, or american alligators, but most of the green iguanas, red-eared s ... | 0 | 29313469 |
| improving amphibian genomic resources: a multitissue reference transcriptome of an iconic invader. | cane toads (rhinella marina) are an iconic invasive species introduced to 4 continents and well utilized for studies of rapid evolution in introduced environments. despite the long introduction history of this species, its profound ecological impacts, and its utility for demonstrating evolutionary principles, genetic information is sparse. here we produce a de novo transcriptome spanning multiple tissues and life stages to enable investigation of the genetic basis of previously identified rapid ... | 0 | 29186423 |
| exploratory behavior of a native anuran species with high invasive potential. | exploratory behavior can be a key component of survival in novel or changing environments, ultimately determining population establishment. while many studies have investigated the behavior of wild animals in response to novel food items or objects, our understanding of how they explore novel environments is limited. here, we examine how experience affects the foraging behavior of a species with high invasive potential. in particular, we investigate the movement and behavior of cane toads as a f ... | 0 | 29030724 |

| structure of the toad's urinary bladder as related to its physiology. | the structure of the urinary bladder of the toad bufo marinus was studied by light and electron microscopy. the epithelium covering the mucosal surface of the bladder is 3 to 10 microns thick and consists of squamous epithelial cells, goblet cells, and a third class of cells containing many mitochondria and possibly representing goblet cells in early stages of their secretory cycle. this epithelium is supported on a lamina propria 30 to several hundred microns thick and containing collagen fibri ... | 1961 | 13733732 |
| the importance of calcium in poststimulation potentiation. | isotonic contractions recorded both before and during poststimulation potentiation in the toad isolated ventricle (bufo marinus) revealed that the phenomenon of poststimulation potentiation was not altered by the presence or absence of the catechol amines, or by the specific amine antagonist, dci. similarly the inhibitors, sodium fluoride and sodium iodoacetate, were without effect. changes in [ca(++)], [mg(++)], and [na(+)] affected the degree of potentiation. high [ca(++)] as well as the cardi ... | 1961 | 13728035 |
| actions of aminoacids on the isolated hemisected spinal cord of the toad. | the actions of a series of amino-acids related to gamma-aminobutyric acid and glutamic acid have been determined upon the isolated and sagittally hemisected spinal cord of the toad, bufo marinus. slow and fast components of the ventral root reflex responses following dorsal root stimulation were depressed by gamma-aminobutyric acid and by a series of neutral amino-acids having a similar structure. the relative depressant potencies of the members of this series were determined by comparison of th ... | 1961 | 13718946 |
| studies on the movement of water through the isolated toad bladder and its modification by vasopressin. | measurements of diffusion permeability and of net transfer of water have been made across the isolated urinary bladder of the toad, bufo marinus, and the effects thereon of mammalian neurohypophyseal hormone have been examined. in the absence of a transmembrane osmotic gradient, vasopressin increases the unidirectional flux of water from a mean of 340 to a mean of 570 microl per cm(2) per hour but the net water movement remains essentially zero. in the presence of an osmotic gradient but without ... | 1962 | 13905689 |
