A data-set representing 10 of the 14 species of pitvipers in the genus Gloydius was assembled based on the NCBI database to explore the phylogenetic relationships within the genus, with an emphasis on Iranian populations. A fragment of the mitochondrial cytochrome b gene was sequenced for 16 specimens of Iranian pitvipers from five locations, and the sequences were added to a final data-set comprising 65 specimens. The Iranian populations belong to a clade containing G. intermedius, G. halys, G. saxatilis, and G. shedaoensis with unresolved within-clade relationships. The Iranian pitvipers clustered with G. halys from Kazakhstan, but more definite taxonomic conclusions on the Iranian populations will require the resolution of species limits among G. intermedius, G. halys, G. shedaoensis, and G. saxatilis. http://zoobank.org/urn:lsid:zoobank.org:pub:BA396891-654E-47C4-B9F0-5DD77985BFB7

Eumops maurus and Eumops hansae are rarely captured Neotropical molossid bats for which information on taxonomy, natural history, and spatial distribution are scarce. This translates into a poor understanding of their ecology and limits the delimitation of useful characters for their identification. Here, we describe records of these two molossids from the Central Brazilian Amazon, providing data on their external and craniodental morphology, DNA barcode (COI) sequences complemented by acoustic data for the species. Morphological characters, DNA sequence data and phylogenetic relationships within the genus Eumops were consistent with those previously described for both species. Echolocation call characteristics did not differ significantly so as to be useful for separating E. maurus and E. hansae from other congeners. Our records are, respectively the first and the second for Central Amazonia as one individual previously attributed to Eumops amazonicus from Manaus may be considered a junior synonym for E. hansae. These new records increase the extent of the species’ known ranges, partially filling in previous existing gaps in their distribution in central South America. Our data further suggest that these molossid bats forage in a wider range of habitats than previously thought.

A new species of Takedactylus Naruse & Maenosono, 2012, and a new genus and species of Aphanodactylidae are described from Japan. Takedactylus compressus n. sp. is collected from Ogasawara Islands. This new species is distinct from the only congener, Takedactylus masatsunei, by the shapes of the carapace, third maxilliped and the ambulatory legs. Another new species, monotypic Lichtylus kaisha n. gen., n. sp., is distinct from all other aphanodactylid species, in generic level, in the shape and position of the palp of third maxilliped, relatively long and slender ambulatory legs, and a combination of other important characters, i.e. the contour of the carapace, the degree of gap between third maxillipeds, condition of the distoflexor corners of second to fifth ambulatory propodi, and relative length of ambulatory dactyli. The present study brings the number of aphanodactylid taxa to 7 genera and 15 species. http://zoobank.org/urn:lsid:zoobank.org:pub:0B01E38B-A542-4D22-966F-43B01E8D57D5 http://zoobank.org/urn:lsid:zoobank.org:act:C1EAADE1-1774-4EED-B62D-8EB2BFDC1C32 http://zoobank.org/urn:lsid:zoobank.org:act:195D7820-DB42-4BD6-AF66-F8C91A42B3FE http://zoobank.org/urn:lsid:zoobank.org:act:8A2C77F2-184D-4D7F-9317-03D6C8FC8D0D

A new species of Parapharyngiella Willems, Artois, Vermin, Backeljau & Schockaert, 2005, Parapharyngiella caribbaea n. sp., is described from Cuba. It differs from Parapharyngiella involucrum Willems, Artois, Vermin, Backeljau & Schockaert, 2005, the only other species in this genus, by a much more posterior position of the pharynx, indicating that the anterior position of the pharynx is not a diagnostic character for the genus. It also differs in the sclerotized copulatory organ having a protuberance that is longer than the mantle. A morphological reassessment of the two known populations of P. involucrum (Zanzibar and Spain) reveals that these populations differ in many details, indicating that they belong to two different species. The population from Spain, therefore, is considered a separate species: Parapharyngiella steenkistei n. sp. Moreover, Proxenetes mackfirae Karling, 1978 is transferred to the genus Parapharyngiella. http://zoobank.org/urn:lsid:zoobank.org:pub:A78F4971-7193-461B-B161-99D2DB9D531A

Opportunistic nocturnal catch-and-release turtle surveys were conducted on three nearshore, shallow coral reefs that fringe the main navigation channel to Cockburn Harbour, South Caicos, between 2005 and 2015. A total of 117 captures were made, representing 73 individual turtles (32 green, 41 hawksbill). Almost half of the green turtles were recaptured on at least one occasion, with a maximum time at liberty of 574 days (median = 94 days). Only 20% of hawksbill turtles were recaptured, with a maximum time at liberty of 587 days (median = 120 days). These data suggest that the study sites are utilised by a combination of transient visitors and short to medium-term resident turtles. However, no evidence of long-term nocturnal site fidelity was found. The size ranges observed in both species indicate that all turtles were immature, and the minimum sizes are consistent with previously reported settlement sizes from the region. Despite the lack of long-term fidelity, turtles were regularly encountered over the course of the study, indicating that these reefs are an important nocturnal refugium for local juvenile turtles in general.

Mygalomorph spiders are rarely found in caves and most of the records appear as accidental or restricted to small populations. The present study took place in iron formations in Carajás region, southeastern Pará state, eastern Brazilian Amazon rainforest. Each cave was sampled twice: dry season (from May to October) and wet season (from November to April). Of the 242 caves sampled, we found mygalomorphs in 98 (40%). The survey yielded 254 specimens, 223 (87.8%) juveniles. Of the 14 species recorded, nine were represented by adults: Dolichothele tucuruiense (Guadanucci, 2007), Hapalopus aymara Perdomo, Panzera & Pérez-Miles, 2009, Acanthoscurria geniculata (CL Koch, 1841), Theraphosa blondi (Latreille, 1804), Nhandu coloratovillosus (Schmidt, 1998), Fufius minusculus Ortega, Nagahama, Motta & Bertani, 2013, and three new are species described here: Guyruita metallophila n. sp., Hapalopus serrapelada n. sp., and Idiops carajas n. sp. Five other “morphospecies” were represented by juveniles only: Ummidia sp. (Ctenizidae), Paratropis sp. (Paratropididae), Bolostromus sp. (Cyrtaucheniidae), Diplura sp. (Dipluridae), and Idiophtalma sp. (Barychelidae). The high number of juveniles suggests two alternatives: some species could be using the hypogean environment as reproductive shelter; the hypogean environment is used as a refuge by immatures. Two species appear to be troglophiles: G. metallophila and H. aymara. https://zoobank.org/urn:lsid:zoobank.org:pub:C92F29CB-4B9C-402D-8AA6-F8251DE49529.

This study investigated the potential of night-time lighting in enhancing the utilization of aerial insects by Oreochromis mossambicus and Clarias gariepinus. Six treatments L0 (Light with no fish), N0 (No light, with no fish), LT (Light with O. mossambicus), NT (No light with O. mossambicus), LC (Light with C. gariepinus) and NC (No light with C. gariepinus) were randomly assigned to aquadams and replicated three times. Two hundred O. mossambicus (60 ± 0.6 g) and 100 C. gariepinus (90 ± 0.8 g) were stocked to assigned aquadams. Two other treatments designated FT (O. mossambicus fed on pellets) and FC (C. gariepinus fed on pellets), were added. SGR was higher (0.31 g/day) in O. mossambicus subjected to night-time lighting than those that were not (0.05 g/day). C. gariepinus under the night-time lighting also had a higher SGR (0.30 g/day) than the ones that were not (0.26 g/day). However, in both species the growth rate was lower when compared to those fed on commercial pellets. Oreochromis mossambicus benefited more from night-time lighting. The most abundant aerial insects were moths and beetles. The serial slaughter method was used to determine the gastric evacuation rate of moths and beetles in O. mossambicus and C. gariepinus. Moths were evacuated faster (−0.235) than beetles (−0.108) in O. mossambicus. In C. gariepinus, the gastric evacuation of moths was also faster (−0.40) than beetles (−0.36). This implies digestion efficiency was higher in moths than beetles. Water physico-chemical variables were analysed once a week and they were not affected by night-time lighting.

Water physico-chemical variables were analysed once a week and they were not affected by night-time lighting.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":"30 1","pages":"156 - 169"},"PeriodicalIF":0.9,"publicationDate":"2017-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2017.1362841","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48213590","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}

In addition to the six species of Xiphocentron Brauer, 1870 currently recorded in Brazil, two new species of X. (Antillotrichia) are described and illustrated in this work: X. (Antillotrichia) acqualume n. sp. and X. (Antillotrichia) jaguare n. sp. Caddisflies in the genus Xiphocentron usually present diurnal activity and are not readily attracted to lights. However, all species included here were collected using light traps during nighttime. The new species can be easily distinguished by having a small cell enclosing the nigma on the forewing. The specimens were collected in the Parque Nacional da Serra da Canastra, a significant mountain range located in the state of Minas Gerais, southeastern Brazil. http://zoobank.org/urn:lsid:zoobank.org:pub:3DBCFECD-7CBD-4A80-9A3C-9C2FCD8FCEA1
除了在巴西记录到的6种剑蛾(Xiphocentron Brauer, 1870)外，本文还描述并说明了两种新种:X. (Antillotrichia) acqualme n. sp.和X. (Antillotrichia) jaguare n. sp.剑蛾属的Caddisflies通常在白天活动，不容易被光吸引。然而，这里所有的物种都是在夜间用灯捕获的。新种可以很容易地通过在前翅上有一个小细胞包裹着nigma来区分。这些标本是在位于巴西东南部米纳斯吉拉斯州的一座重要山脉——卡纳斯特拉国家公园收集的。http://zoobank.org/urn:lsid:zoobank.org:pub:3DBCFECD-7CBD-4A80-9A3C-9C2FCD8FCEA1

We have investigated characteristics of colony site of three sympatric breeding tern species on small islands of a subtropical region, the Persian Gulf. The three most populous ground-nesting waterbird species – Bridled Tern Onychoprion anaethetus, Lesser Thalasseus bengalensis and Greater Thalasseus bergii Crested Terns – were studied during the 2009–2011 breeding seasons. The average area size of mixed colonies was 454 m2. The density of nests of the Bridled Tern was 846 nests/ha. The proportion of the number of nests in a mixed colony for Lesser Crested Tern (5546 nests) was approximately 10-fold compared to the Greater Crested Tern (542 nests). The density of Bridled Tern nests/ha was significantly higher in areas with 50–75% vegetation cover (>1200 nests/ha) than in areas of <5% vegetation cover (72–105 nests/ha) (p < 0.05). Mixed colonies of the Lesser and Greater Crested Terns were located on unvegetated land, at an average distance of 4.1 m to vegetation, and on sandy soil (79.4% on average) and above high spring tide water lines (0.59 m on average). There were more potential nesting areas than occupied areas for the mixed colonies of the Lesser and Greater Crested Terns, indicated that they did not face nest site limitation. https://zoobank.org/urn:lsid:zoobank.org:pub:7523ABA7-45E1-4067-8EF7-557E65EC8249
