| historical biogeography resolves the origins of endemic arabian toad lineages (anura: bufonidae): evidence for ancient vicariance and dispersal events with the horn of africa and south asia. | the arabian peninsula is home to a unique fauna that has assembled and evolved throughout the course of major geophysical events, including the separation of the arabian plate from africa and subsequent collision with eurasia. opportunities for faunal exchanges with particular continents occurred in temporally distinct periods, and the presence of african, western eurasian, and south asian derived taxa on the arabian peninsula signifies the complexity of these historical biogeographic events. th ... | 2015 | 26245197 |
| effects of copper, zinc and dragonfly kairomone on growth rate and induced morphology of bufo arabicus tadpoles. | it is well documented that many amphibian species can detect chemical signals from predatory invertebrates and subsequently develop alternate phenotypes that are protective against predation. the effects of metallic pollutants on the development of predator-induced morphology have not previously been reported. tadpoles of the arabian toad bufo arabicus were exposed for 20 days to copper (0, 10 or 100 μg/l), zinc (0, 10 or 100 μg/l) and kairomones of larval dragonflies (crocothemis erythrea 1 dra ... | 2011 | 21251714 |
| induction of hyperpigmentation and heat shock protein 70 response to the toxicity of methomyl insecticide during the organ development of the arabian toad, bufo arabicus (heyden,1827). | methomyl (met) is a carbamate insecticide which is used as a substitute for organophosphorus compounds to protect crops against insects. the present study aims to evaluate the cytoprotection response of pigment cells and heat shock protein 70 (hsp70) after exposure to met during the tadpole developmental stages of the arabian toad, bufo arabicus. three developmental larval stages of the toad were selected and divided into two groups; control and met-exposed (met-ex) tadpoles (10ppm). met-ex tadp ... | 2019 | 31492089 |
| teratogenicity and neurotoxicity effects induced by methomyl insecticide on the developmental stages of bufo arabicus. | methomyl (met) is a carbamate insecticide that has been widely used to protect the crop against insects as an alternative for organophosphorus insecticide. thus the present study aims to evaluate the potential toxic effects of met on the developmental stages of bufo arabicus. tadpoles were classified into three stages (25, 37, 40). every stage was divided into two groups, control and met-treated group (10 ppm for two weeks) after lc50 determination in acute toxicity test for 96 h. control and me ... | 2020 | 30610886 |
