In examinations of ca. 1,300 Scincella specimens, one Scincella lateralis specimen and three S. boettgeri specimens were observed to have malformed digits, i.e., ectrodactyly. Each of these specimens had a malformation in only one limb. One S. lateralis specimen lacked digits I–III of manus, and three S. boettgeri specimens lacked digits I, II, or I and II of pedes. Micro-computed tomography scanning revealed that the phalanges and metacarpals of digits I–III were absent in the malformed S. lateralis specimen, whereas the malformed S. boettgeri specimens lacked all phalanges for externally absent toes but had five metatarsals, despite these being shorter in the absent toes than those in normal toes. Although malformed limbs have been reported previously in lizards, this is the first report based on osteological descriptions. Some genera of Scincidae include species that have undergone phylogenetic reduction of their digits. In such species, the developmental order of the phalanges and metacarpals/metatarsals is well-known from embryological studies. With reference to this developmental mechanism, we also discuss the assumed development of the malformed specimens observed in this study.","PeriodicalId":56053,"journal":{"name":"Current Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49466344","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 found 44 reports of I. iguana, of which 93% were removed from the wild. Thirty-nine reports were records kept by one non-government organization, one report from a government agency, and four reports from community members. Reports were sporadic between 2002 and 2011, but have occurred in every calendar year since 2012, predominately during March, July and October. Report locations were distributed broadly across 16 administrative districts, including heavily developed city areas, indicative of released or escaped pets being the source. Although there was evidence of two individuals living in one locality, we found no major concentrations of reports to indicate established populations. Nevertheless, these data should not be assumed benign since some established populations of I. iguana elsewhere have only become evident following prolonged periods of sporadic reports. It is therefore plausible that emerging reports in Hong Kong may represent a contemporary invasion presently under way. Public reporting of I. iguana plays an important role in preventative invasive species management. However, we also found cases where I. iguana reported as free-living were more likely the same captive I. iguana, highlighting potential errors with community science.","PeriodicalId":56053,"journal":{"name":"Current Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47847601","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 tadpoles were collected from various water bodies of the state of Odisha over three consecutive breeding seasons (2018–2020). Oral and internal buccal characters were analysed independently for Gosner developmental stages 25 to 46. The upper labium has four labial tooth rows with a medial gap in the three rows proximal to the mouth, whereas the lower labium has three rows with a medial gap in the row proximal to the mouth. The order of length of denticle rows is A2>P1>P2>A1>P3>A3>A4 with a dental formula of A4(3)/P3(1). The food spectrum of the tadpoles included mostly phytoplanktons (represented by six classes and 51 genera) followed by zooplankton (two classes and four genera). Three Bacillariophyceae genera (Navicula, Pinnularia, and Synedra) contributed most of the gut contents. Scenedesmus was the major food items in Chlorophyceae family and had the highest numeric frequency (7.63%) among all the food items. Other prevalent food items included Zygnematophyceae, Cyanophyceae, Euglenophyceae, Rotifera, Ulvophyceae and Copepoda.","PeriodicalId":56053,"journal":{"name":"Current Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43507205","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}

Thus, we examined the stomachs of 239 E. t. friesi specimens collected on Okinawajima Island from July 2018 to November 2019. Stomach contents were identified to the species level whenever possible based on morphological observations and/or DNA analyses. Of the 239 snake specimens, 39 (12 males, 16 females, and 11 juveniles) had contents in their stomach, including 67 prey items, 75% of which were mammals (Muridae and Soricidae) and the rest of which were birds (Pycnonotidae, Cisticolidae, and Columbidae). Rattus rattus occurred most frequently; 25 of the 39 snakes examined had this species in their stomachs. All avian prey items detected were nestlings and eggs. Twelve snakes had multiple prey items in their stomach, including in most cases either nestlings of passerine birds or infants or subadults of R. rattus. Therefore, E. t. friesi is an endotherm consumer that occasionally preys on nestlings and infant rats. These food habits suggested that E. t. friesi uses various habitats, from the humus layer on the ground to the branches of trees, for foraging. Several endangered endemic rodent and bird species exist in the northern area of Okinawajima Island; thus, our results provide a warning about potential negative impact on such animals when E. t. friesi expands its range to the northern part of the island.","PeriodicalId":56053,"journal":{"name":"Current Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43606082","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}
