As a result of our field trips in Son La and Lai Chau provinces, northern Vietnam, this study provides novel data about the feeding ecology of P. megacephalus. We used the stomach-flushing method to obtain the stomach contents of 232 individuals at three sites. A total of 19 prey categories with 415 items were found in the stomachs of P. megacephalus. This species has a wide food spectrum and the dominant prey items of P. megacephalus were Araneae, Opiliones, insect larvae, Blattodea, Coleoptera, Hemiptera, Hymenoptera, Isoptera, and Orthoptera. The importance index for these categories ranged from 1.87% to 31.03%. Orthoptera was the prey category with the highest frequency of occurrence and its representatives were found in 81 stomachs. The result of multiple regression analysis indicated that both snout-vent length and mouth width were associated positively with prey sizes consumed by P. megacephalus.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48549283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asian Common Toad (Duttaphrynus melanostictus) is widely distributed in South Asia, and has been introduced outside its range causing severe ecological problems. We gathered data on morphometrics, habitat and breeding activity of the species in its western edge, North Punjab, Pakistan, of the range. The morphometric measurements of Asian Common Toad showed that the males were 49 ± 3.4 mm in snout vent length while the females were 58 ± 5.5 mm. Of the 13 measurements tested, the factor analysis produced five (head width, forelimb length, femur length, width of upper eyelid and foot length) significant measurements (r 0.80) for male while six (snout-vent length, head width, head length, greatest tympanum diameter, forelimb length, length of tarsus and foot) for female. The substrate of the habitat of Asian Common Toad was recorded as muddy to stony; water with neutral to slightly alkaline pH; dominated by herbs: Cannabis sativa, Parthenium hysterophorus; shrubs: Dodonaea viscosa, Lantana camara; grasses: Cynodon dactylon, Dactyloctenium aegyptium; and hydrophytes Alternanthera sessilis and Centella asiatica. The mean air and water temperature (day) during the breeding period were 27 – 30.5 and 25 – 28.5°C, respectively. The toad species laid eggs in small sized pools with lentic to slow-moving water with the mean depth of 32 – 64 cm. The males were more abundant than females (2.14♂:1♀) at the breeding sites. The advertisement call was of 9.3 ± 0.80 sec duration with a single note and 49.5 ± 6.5 nodes, –7.45 ± 0.95 average amplitude, 776 ± 51.8 Hz minimum frequency and 7011 ± 1680 Hz maximum frequency.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48231373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The P. esculentus complex consists of two parental species, P. lessonae and P. ridibundus, as well as their hemiclonal (sometimes meroclonal) hybrid, P. esculentus. DNA flow cytometry, genetic and morphometric analyses were used to examine water frog compositions in 27 localities (n = 212) throughout the Dniester River valley in Moldova. Two species were revealed in the studied region (42% individuals were P. esculentus and 58% P. ridibundus). All frogs proved to be diploid. We registered the first species in 74% localities and the second in 78%. Populations, where we found only P. ridibundus occurred in 26% localities and only P. esculentus in 22%, while mixed population systems in 52%. Both species were usually observed in open water bodies and rivers that flow down through agricultural land and urban areas. In populations of P. esculentus the number of males strongly exceeded (90%) the number of females. The half of studied hybrid males was sterile, and most of fertile hybrid males produced sperm with the genome of P. lessonae. Several hybrid males gave the mixture of sperm with genomes of P. lessonae and P. ridibundus (amphispermy) and only one male with the P. ridibundus genome. Both species had the mitochondrial DNA of P. ridibundus. Based on nuclear markers, in P. esculentus and P. ridibundus we revealed the presence of alleles of the closely related Anatolian species P. cf. bedriagae. This might affect the successful reproduction of hybridogenetic P. esculentus. However, comparison of percentage of sterile males and alleles of P. cf. bedriagae among hybrids showed no correlation.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47440972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Minimal and maximum ages of males of the species were three and seven years, respectively. The age of females ranged from three to six years. Mean age for both sexes was 4.0 years. The majority of males (46.2%) were three years old, most females (58.8%) were four years old. The age of sexual maturity was reached after three hibernations (46% in males and 24% in females). The majority of toads breed once at the age of three or four years. Only few (18% in females and 23% in males) individuals in this population were older. Harsh high-altitude cold desert conditions and limited food resources may cause high mortality of the toads. The correlation between the minimal age at sexual maturity and the degree of dryness of climate was demonstrated among species of the genus Bufotes. As a rule, toads which live in more humid climatic conditions mature earlier. Perhaps, this explains that substantial part of semi-aquatic individuals of B. baturae in the hot spring mature at earlier age (3 years) than other polyploid species (4 – 5 years) that inhabit arid environments. In both sexes of B. baturae, growth rate was similar to that of other closely related high-mountain species, diploid B. latastii and triploid B. pseudoraddei.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42959600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a part of the natural history of V. timorensis, which includes cannibalism of juveniles in wild populations on Sabu Island, Indonesia. Our current records of adult body sizes denote a range of mature females, some of which are likely to have reproduced. Body sizes of Timor monitors on Timor and Sabu suggest a seasonal mating of wild lizards that coincides with dry season and hatching of eggs during the wet season.

It had the typical erythrocyte morphology showing eclipse shape with a central nucleus without significant difference between males and females. White blood cells (or leukocytes) in the snakes were a heterogeneous group with different nucleus shape and also shared a similar size between sexes. Interestingly, the length of thrombocytes was significantly different (P 0.05): longer in the male and shorter in the female snakes. From the blood smear technique, the heterogeneous group of the snake leukocyte included azurophil, heterophils neutrophil, basophil, lymphocyte, and monocyte without eosinophil. Remarkably, the highest proportion of the snake leukocyte was lymphocyte, followed by azurophils, and neutrophil. This proportion was similar in both sexes.
