“…The most severe temperatures, which occurred during summer afternoons (Table 3A), may affect salamander activity, but it is likely that forest salamanders would be in subterranean refuges at this time of the year (Semlitsch, 1981;Faccio, 2003;Rothermel and Luhring, 2005). The study was implemented almost 2 months following the peak of amphibian surface activity associated with spring migrations to breeding pools (approximately 1 April; Paton et al, 2000), we would expect even smaller differences in microclimate between cut and control locations in early spring, prior to tree leaf development. Nevertheless, effects of minor, but chronic increases in temperature on amphibians and on their ability to behaviorally or physiologically themoregulate to these changed conditions is complicated and not well understood (Duellman and Trueb, 1994).…”

“…For pond-breeding adult amphibians and recently metamorphosed juveniles that undertake overland migrations, migratory activity may be highly dependent upon adequate climatic factors to mitigate the risk of desiccation. Breeding migrations and the emigration of recently metamorphosed juveniles from wetlands have been corre-lated to daily rainfall for many species (e.g., Anderson 1967;Semlitsch 1981Semlitsch , 1985Sexton et al 1990; Tanner 2004, 2005), and the seasonal phenology of amphibian reproductive migrations is also well-documented for populations of many species (e.g., Beebee 1995;Semlitsch et al 1996;Paton et al 2000;Gibbs and Briesch 2001). However, the timing of migration varies among species (Paton et al 2000), among years (Gibbons and Semlitsch 1991), and with latitude within a single species (Brandon and Bremer 1967;Morin 1983).…”

Pond-breeding amphibians from temperate regions undertake overland migrations to reproduce in aquatic habitats. In turn, their offspring metamorphose and emigrate to upland, terrestrial habitats. We examined the diel patterns and daily variability of migrations of adult and juvenile amphibians in response to climatic cues. Of the eight species ( Ambystoma talpoideum (Holbrook, 1838), Ambystoma tigrinum (Green, 1825), Bufo terrestris (Bonnaterre, 1789), Hyla gratiosa LeConte, 1856, Pseudacris crucifer (Wied-Neuwid, 1838), Pseudacris ornata (Holbrook, 1836), Rana sphenocephala Cope, 1886, and Scaphiopus holbrookii (Harlan, 1935)) that we observed, all migrated almost exclusively at night except for the recently metamorphosed B. terrestris, which frequently migrated diurnally (>50% of captures). Additionally, we correlated daily captures of adult and juvenile A. talpoideum, A. tigrinum, B. terrestris, and R. sphenocephala to maximum and minimum daily temperatures, number of previous days without rain, total rainfall during the previous 24 h, and interactions of these variables. Rain was often the most important predictor of amphibian movements. However, species differed in their response to climatic factors, with some species and age classes being more dependent on rain for migrations than others. Rapid changes in regional weather patterns may affect species’ migrations differently, possibly altering arrival times of reproductive adults or affecting the likelihood of successful migrations.

“…Few studies have quantified the movement phenology of pond‐breeding amphibians, including information on both the timing of immigration by adults and emergence by metamorphs ( but see Murphy 1963; Shoop 1974; Semlitsch 1985; Petranka & Thomas 1995; Paton et al 2000. Usually only qualitative information on seasonal variation in movements is available for most parts of North America ( Wright & Wright 1949; Klemens 1993; Semlitsch et al 1996).…”

Researchers suggest that regulatory agencies interested in protecting pond-breeding amphibians should consider wetland isolation, wetland size, and pond hydroperiod (total number of days pond is flooded annually) when modifying existing wetland regulations. Another criterion that has received less attention is the effect of the timing of inundation on the reproductive success of pond-breeding amphibians. Over 3 years, we monitored the timing of movements of adult and recently metamorphosed anurans and caudates at seven small, isolated wetlands in southern Rhode Island. Based on dates of immigration for adults and emigration for metamorphs, we concluded that different species of amphibians require ponds to be flooded for 125 days to at least 580 days. For species that breed primarily in seasonally flooded ponds, 95% of metamorphs had emigrated from breeding ponds by 31 July in only two species ( Rana sylvatica and Ambystoma opacum ), whereas species using semipermanent ponds required inundation until 18 November. Our results suggest that in most years ponds must be inundated for 4-9 months, with water in ponds from March through August, for successful reproduction of the majority of pond-breeding amphibians in Rhode Island. We recommend that biologists gather data on amphibian movement phenology in other regions to help regulators and managers develop relevant legislation to protect the habitat of pond-breeding amphibians. Uso de la Fenología de Anfibios que se Reproducen en Estanques para Desarrollar Estrategias de ConservaciónResumen: Los investigadores sugieren que las agencias reguladoras interesadas en la protección de anfibios que se reproducen en estanques deberían tomar en consideración el aislamiento de los humedales, el tamaño del humedal y el hidroperíodo del estanque (número total de días del año que el estanque está inundado) para modificar las regulaciones existentes de humedales. Otro criterio que ha recibido menor atención es el efecto del tiempo de ocurrencia de la inundación sobre el éxito reproductivo de los anfibios que se reproducen en estanques. Monitoreamos por más de tres años los tiempos de los movimientos de anuros y acudados adultos y recién metamorfoseados en siete humedales pequeños y aislados ubicados al sur de Rhode Island. En base a los datos de inmigración para adultos y emigración para metamorfos, concluimos que diferentes especies de anfibios requieren que los estanques estén inundados por 125 días hasta por lo menos 580 días. Para las especies que se reproducen principalmente en estanques inundados estacionalmente, el 95% de los metamorfos habían emigrado de los estanques de reproducción para el 31 de Julio ( Rana silvatica y Ambystoma opacum ), mientras que las especies que emplearon estanques semipermanentes requirieron de la inundación hasta el 18 de Noviembre. Nuestros resultados sugieren que en la mayoría de los años los estanques usados por anfibios reproductores deben estar inundados por 4-9 meses, con agua en los estanques desde Marzo y hasta Agosto para que se de una re...
