Does gestation or feeding affect the body temperature of the golden lancehead, Bothrops insularis (Squamata: Viperidae) under field conditions?

When Basking Is Not an Option: Thermoregulation of a Viperid Snake Endemic to a Small Island in the South Atlantic of Brazil

“…Although juveniles may bask more often than adults of certain snakes (Blouin-Demers and Weatherhead, 2001), B. insularis was not observed basking. Feeding and pregnancy, known to cause a thermophilic response in some snakes (Peterson et al, 1993), was previously found not to affect field T b of B. insularis (Bovo et al, 2010).…”

“…Also, in (B) E values calculated according to Hertz et al (1993) are depicted by dashed and gray bars for day (0600-1800 h) and night (1800-0600 h), respectively. Bovo et al, 2010) while the typical prey of B. insularis are not (Bovo et al, 2010;A. Macarrão, pers.…”

<b>Monitoramento das oscilações anuais nos níveis de testosterona plasmática e andrógenos fecais de machos de jararaca-ilhoa (<i>Bothrops insularis</i>) mantidos em cativeiro</b>

“…This study contributes to the validation of a new longitudinal evaluation method of sex steroids in B. insularis, with the knowledge of the reproductive biology of tropical snakes and the conservation of endangered animals. ANDRADE, 2010;MARQUES et al, 2012;GUIMARÃES et al, 2014), o conhecimento sobre a biologia reprodutiva de Bothrops insularis ainda é principiante e as informações a respeito da sazonalidade são conflitantes. Enquanto alguns trabalhos realizados in situ e a partir de espécimes depositados em coleção científica (KASPEROVICZUS, 2009;ALMEIDA-SANTOS, 2013) afirmam haver sazonalidade reprodutiva de fêmeas e machos, inclusive com um período de quiescência testicular, outro trabalho realizado pelo mesmo grupo mostra não haver diferença expressiva na qualidade seminal de animais mantidos em cativeiro (SILVA et al, 2015).…”

<b>Influência do ciclo reprodutivo na biologia termal de <i>Crotalus durissus </i>neotropical (Serpentes, Viperidae) em cativeiro</b>

“…On the other hand, pregnant females of some species exhibit higher and/or less variable body temperatures than nonpregnant females or males (Charland and Gregory, 1990;Chiaraviglio, 2006). However, pregnancy has no detectable effect on the thermoregulation of some species (Bovo et al, 2010). Viviparous females retain their embryos in utero throughout development and give birth to fully formed young.…”
