“…Several individual frogs used burrows during approximately 70% of relocations. Other amphibian species, notably salamanders, are known to use mammal burrows (Madison and Farrand, 1998;Hasumi et al, 2009). Microhabitats within mammal burrows offer respite in dry or cold climates; soil temperature and humidity are both higher in areas with burrows of the plateau pika, a species found at our study sites (Smith and Foggin, 1999).…”

ABSTRACT.-We studied the movement patterns and habitat selection of 33 radio-tagged Plateau Brown Frogs (Rana kukunoris) in the Zoige Alpine Wetland in southeastern Qinghai-Tibet plateau. Our goals were to (1) understand postbreeding movement patterns of R. kukunoris; (2) describe microhabitat use, with special reference to use of small mammal burrows; (3) test for movement pattern and microhabitat use differences between sexes and between seasons; and (4) provide a preliminary description of overwintering sites. We found no differences in movement patterns between sexes in R. kukunoris, however, directional movement trends differed between habitats. Male and female R. kukunoris showed similar microhabitat selection with regard to air temperature, relative humidity, and vegetation height. Although males used mammal burrows more frequently than females at one study site, BaiHua, both sexes used these microhabitats frequently during their movements. Overwintering sites of R. kukunoris were characterized by year-round flowing water. Results from this study will assist in making decisions about conservation and land protection for this species.

“…Individuals also tend to move more quickly in inhospitable habitats (Hartung 1991;Tramontano 1997). Traffic-associated stimuli as light and noise can affect amphibian behaviour ) and other species as snakes and salamanders exhibit road avoidance behaviour (Andrews and Whitfield Gibbons 2005;Madison and Farrand 1998). These observations suggest that amphibian movement and behaviour can be affected by roads.…”

An extensive and expanding infrastructural network destroys and fragments natural habitat and has detrimental effect on abundance and population viability of many amphibian species. Roads function as barriers in the landscape. They separate local populations from each other or prevent access to necessary resources. Therefore, road density and traffic intensity in a region may have severe impact on regional as well as local connectivity. Amphibians may be able to detect and avoid unsuitable habitat. Individuals' ability to avoid roads can reduce road mortality but at the same time road avoidance behaviour, can increase the barrier effect of the road and reduce connectivity. We use an individual based model to explore how changes in road mortality and road avoidance behaviour affect local and regional connectivity in a population of Moor frogs (Rana arvalis). The results indicate that road mortality has a strong negative effect on regional connectivity, but only a small effect on local connectivity. Regional connectivity is positively affected by road avoidance and the effect becomes more pronounced as road mortality decreases. Road avoidance also has a positive effect on local connectivity. When road avoidance is total and the road functions as a 100% barrier regional connectivity is close to zero, while local connectivity exhibit very elevated values. The results suggest that roads may affect not only regional or metapopulation dynamics but also have a direct effect on local population dynamics.

“…Studies that include both adult and juvenile amphibian movements are particularly critical because they provide insights into emigration (movements to and from breeding ponds) and dispersal (one-way movement from one breeding pond to another) behaviors [13], and habitat requirements in upland forests [4,7,8,[10][11][12][13][14]. Details on survival and resource needs in upland habitat are often scarce, mainly because amphibians often live in forest floor refuges or tunnels throughout the nonbreeding period [14][15][16][17][18][19][20][21].…”

“…Details on survival and resource needs in upland habitat are often scarce, mainly because amphibians often live in forest floor refuges or tunnels throughout the nonbreeding period [14][15][16][17][18][19][20][21]. Some reports suggest the use of "buffer" or "life" zones to protect upland habitat [4,[7][8][9][10][11][12]22], and many of these studies were initiated because of immediate necessity for buffer zone policies in order to offer at least some protection for amphibians in a growing number of permit applications and court cases involving land development.…”

“…Unfortunately, for some amphibian species, accurate and localized guidelines encompassing the long-term habitat use and survival of all classes of individuals within populations are still needed. Even where upland data are becoming more available, additional solutions for long-term population maintenance are necessary [3,12,14,16,[23][24][25][26][27].…”

Most amphibians use both wetland and upland habitats, but the extent of their movement in forested habitats is poorly known. We used radiotelemetry to observe the movements of adult and juvenile eastern tiger salamanders over a 4-year period. Females tended to move farther from the breeding ponds into upland forested habitat than males, while the distance a juvenile moved appeared to be related to body size, with the largest individuals moving as far as the adult females. Individuals chose refugia in native pitch pine-oak forested habitat and avoided open fields, roads, and developed areas. We also observed a difference in potential predation pressures in relation to the distance an individual moved from the edge of the pond. Our results support delineating forested wetland buffer zones on a case-by-case basis to reduce the impacts of concentrated predation, to increase and protect the availability of pitch pine-oak forests near the breeding pond, and to focus primarily on the habitat needs of the adult females and larger juveniles, which in turn will encompass habitat needs of adult males and smaller juveniles.
