If animals avoid road surfaces or are unable to follow conspecific trails across such surfaces, previously continuous populations may be fragmented. We gathered data on the effects of a small (4-m wide) gravel road on the behavior and trail-following abilities of garter snakes (Thamnophis sirtalis parietalis) in Manitoba, central Canada. As expected, the road surface had less vegetation cover, a more open canopy and, thus, higher incident radiation than did the surrounding grassland. Contrary to expectations, however, substrate temperatures were lower on the road than in its surrounds, because of the higher reflectivity of the road's surface. On a nearby asphalt road, substrate temperatures were relatively high on the road surface only in the evening, as...

Three synonymous genes encode calmodulin in a reptile, the Japanese tortoise, Clemmys japonica
Provedor de dados: 74
Autores: Shimoda,Kouji; Miyake,Toshihiro; Kimura,Jun; Maejima,Kazuyoshi.
Three distinct calmodulin (CaM)-encoding cDNAs were isolated from a reptile, the Japanese tortoise (Clemmys japonica), based on degenerative primer PCR. Because of synonymous codon usages, the deduced amino acid (aa) sequences were exactly the same in all three genes and identical to the aa sequence of vertebrate CaM. The three cDNAs, referred to as CaM-A, -B, and -C, seemed to belong to the same type as CaMI, CaMII, and CaMIII, respectively, based on their sequence identity with those of the mammalian cDNAs and the glutamate codon biases. Northern blot analysis detected CaM-A and -B as bands corresponding to 1.8 kb, with the most abundant levels in the brain and testis, while CaM-C was detected most abundantly in the brain as bands of 1.4 and 2.0 kb. Our...

Morphological Characterization of Gecko's (Eublepharis macularius) Glial Cells in Culture
Provedor de dados: 77
Autores: Grzesiak,Jakub; Marycz,Krzysztof; Szarek,Dariusz; Jarmundowicz,Wlodzimierz.
Central nervous system of reptiles has the ability to grow and regenerate during adult life of the animal. Therefore, cells creating CNS of this animal class should compound substances or molecules enabling neuroregeneration. Cells directly involved in this process have not been clearly characterized, especially in cell culture environment. Morphology of reptilian glial adherent cells should be known better to find any differences from mammalian CNS cells. We isolated glial cells from olfactory bulb and cerebrum from gecko (Eublepharis macularius) and cultured separately. We have observed populations of cells with proliferative capacity in both types of cultures. Also, we have detected lipid molecules deposits within their cytoplasm, which localization was...

Provedor de dados: 19
Autores: Yanagawa, Hisashi; Akisawa, Masae.
Road kills of medium- and small-sized mammals, reptiles and amphibians were surveyed in eastern Hokkaido, northern Japan. Four hundreds and fifty-five carcasses of medium- and small-sized mammals, 17 carcasses of reptiles and 1051 carcasses of amphibians were collected from April 1996 to March 1998. In mammals, the species with the highest number of casualties due to traffic accidents was the Big-clawed Shrew with a total of 152 killed, followed by Red Squirrel (94) and Red Fox (85). Road kills of reptiles were low, with only 17 mortalities of four species. In amphibians, a great majority of the mortalities were Ezo Brown Frogs with 1,044 casualties.

The Herpetofauna from Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil): updating species composition, richness, distribution and endemisms
Provedor de dados: 84
Autores: Rocha,Carlos Frederico Duarte; Telles,Felipe Bottona da Silva; Vrcibradic,Davor; Nogueira-Costa,Paulo.
Abstract Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork and on secondary data (from institutional collections and from the literature). We report the occurrence at Ilha Grande of a total of 74 species, being 34 amphibians (all of them anurans) and 40 reptiles (27 snakes, 11 lizards, one amphisbaenian and one crocodylian). Our survey added 14 species to the herpetofaunal list of Ilha Grande (three of amphibians and eleven of reptiles) and removed one species...

Parasites in feces of the endemic rattlesnake, Crotalus triseriatus (Serpentes: Viperidae), from Mexican highlands
Provedor de dados: 103
Autores: Soria-Díaz,Leroy; Rábago-Castro,Jaime Luis; Domínguez-Vega,Hublester; Gómez-Ortiz,Yuriana; Manjarrez,Javier; Garrido-Olvera,Lorena.
ABSTRACT There are few studies about parasitic infections in Crotalus triseriatus (Wagler, 1830), an endemic rattlesnake from the highlands of central Mexico. This species occupies several habitats, from conserved forested regions to heavily impacted landscapes. To increase the parasitological knowledge of this reptile species without impacting populations, we obtained fecal samples of 16 rattlesnakes between 2012 and 2014 from Toluca Valley, Mexico. By using flotation technique, we found oocysts of Eimeria sp. and eggs of Capillariidae sp. The most frequent parasite was Eimeria sp. (62.5%). This study provides the first records of occurrence of parasites in reptilian feces from Mexico. Our results may be important for wildlife conservation purposes, for...

PREDATORY INTERACTION BETWEEN TWO ANURAN SPECIES WITH Thamnodynastes chaquensis (COLUBRIDAE) IN THE BRAZILIAN CERRADO
Provedor de dados: 37
Autores: DIAS-SILVA,Fernanda; Murillo Peixoto COUTO,Rodney; Maiara Cabrera,MIGUEL; ADAMS,Guilherme Brad; BÜHLER,Daniel; PEREIRA,Elvis Almeida.
ABSTRACT Although predatory events are uncommon to be recorded in nature, these data are important tools for understanding prey-predator interaction of the involved species. Snakes of genus Thamnodynastes are known for having an anuran diet, including some species of hylid frogs in their diet. Despite this, this pattern does not include T. chaquensis since there are no records on predation or trophic interaction with hylid frogs. Here, we report the first predatory interaction between T. chaquensis and two hylid frogs in Brazilian Cerrado. The first predation event with treefrog Boana caiapo occurred with success but, the second with B. albopunctata did not. Connecting trophic links within an ecosystem requires in-depth knowledge of its species and their...

A influência dos ritmos circadianos no metabolismo da serpente Bothrops jararaca (Serpentes, Viperidae) - DOI: 10.4025/actascibiolsci.v30i3.5030
Provedor de dados: 3
Autores: Cruz, José Geraldo Pereira da; FURB.
A atividade termorreguladora conduziu a uma busca extensiva para o entendimento das correlações entre as variáveis fisiológicas, incluindo as funções metabólicas e a temperatura corporal. Frequentes observações mostram que algumas serpentes podem se aquecer, sendo este aumento de temperatura independente da temperatura ambiente, indicando a termorregulação bem sucedida. Bothrops jararaca foram expostas a dois ambientes com diferentes temperaturas (20 e 30oC) durante três semanas, sendo mensuradas a temperatura corporal e o consumo de oxigênio. O aumento da temperatura corporal e consumo de oxigênio de Bothrops jararaca ocorreram na fase de escuro do fotoperíodo, consistente para espécies noturnas. Entretanto, antecedendo a fase de escuro, as serpentes em...

Provedor de dados: 49
Autores: Zanella,Noeli; Paula,Almir de; Guaragni,Samara Arsego; Machado,Leonardo de Souza.
The northern part of the state of Rio Grande do Sul was extensively deforested in recent decades, and only isolated fragments of the original vegetation remain. The Parque Natural Municipal de Sertão comprises a remnant of Atlantic Rain Forest, one of the largest fragments in northern Rio Grande do Sul. This study examined the diversity of the herpetofauna, focusing on environmental distribution, seasonality and species richness. We used complementary methods of sampling such as pitfall traps, active search and occasional encounters. We recorded 23 species of frogs, nine snakes and one lizard. With respect to the relationship between amphibians and reptiles and the structural and abiotic factors of the environment, the edge of the fragment showed higher...

ABSTRACT:  This study aimed to describe strip meniscometry test values for Amazona aestiva (turquoise-fronted amazon), Ara ararauna (blue-and-yellow macaw) and Caiman latirostris (broad-snouted caiman). Twenty-one Amazona aestiva and 11 Ara ararauna, healthy, adults of unknown sex, and 37 healthy adult Caiman latirostris (27 males and 10 females), were used in this investigation. All animals were manually restrained and I-Tear® Test strip was inserted for 5 s at the edge of the lower tear meniscus, without touching the eyelid or ocular surface, immediately followed by measurement (millimeter per 5 seconds). No differences were reported between left and right eyes for Amazona aestiva (P = 0.824), Ara ararauna (P = 0.262) and Caiman latirostris (P = 0.679)....
