In the animals exposed to continuous illumination in white containers the skin is seen to become paler (M.I. = 1 to 2). The secretory cells of the pars intermedia appear crammed with secretion granules. Profiles of the rough endoplasmic reticulum are scanty. On the contrary, in the animals reared in the dark in black containers, a striking skin darkening takes place (M.I. = 4 to 5). The pars intermedia secretory cells reveal a definite decrease in the population of endocellular granules and a developed, rough endoplasmic reticulum, characterized by enlarged cisternae filled granular or filamentous material.

A new species is described from the Iberian Peninsula: D. galganoi n.sp., and its genetic divergence from the other Discoglossus taxa is analyzed. In spite of being morphologically similar, D. galganoi and D. pictus are genetically much differentiated: as many as 12 out of the 35 loci electrophoretically tested show distinct alleles in the two species. This allows an easy identification of larvae and adults, both males and females, of D. galganoi and D. pictus, as well as of the other west Mediterranean Discoglossus species, by means of biochemical keys. Two of such keys, based respectively on the loci lactate dehydrogenase-1 (Ldh-1) and adenosine deaminase (Ada) are reported. An attempt is made to estimate the time of evolutionary divergence between the taxa from their genetic distance using both NEI'S formula (1975) and SARICH'S calib...","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"22 1","pages":"69-90"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81544154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Flying males emit an average of 1.08 flashes per second at a temperature of 17°C with occasional dim light emissions during the interflash period. Male flashes may be variable in form and length but are usually composed of a very intense peak accompanied by a series of minor ones. Dim light, which on some occasion has the function of illumination, consists either in a close succession of brief irregular flashes or in a more regular flickering. Females, which do not fly, have little spontaneous flashing activity. Their flashes are usually composed of three peaks, with the interval between the first two peaks increasing exponentially at decreasing temperatures (~ 77 msec at 26°C, 245 msec at 10°C). Females regularly respond with a flash to each light stimulus of steeply rising intensity, regardless of stimulus intensity, length, or spectral range (at least between about ...","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"70 1","pages":"135-184"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83873628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
