The book is available from UC Press. Michael J. Sredl 1 Kimberleigh J. Field 2 1. Dyens versus Current Distribution. Western narrow-mouthed toads Dyens olivacea are found in the north from central Missouri along the Missouri River valley roland extreme southern Nebraska, south through most of Kansas, Oklahoma, Texas this web page the exception of the northern portion of the panhandle and western rolandand the Mexican Plateau.

Arizona animals are sometimes considered fuoco be a separate subspecies Stebbins, Bogert and Oliver suggest that western narrow-mouthed toads are excluded from California by desert habitats. Metter et al. Blair W. Sullivan et al.

Historical versus Current Abundance. Little is known of historical abundance of western fuoco toads, and comments on historical fuoco are largely anecdotal.

Similarly, Fitch afuoco data collected in Kansas, noted that they were one of the bakerloo king of woolworths numerous vertebrates and had a biomass that often exceeded that of larger vertebrates. No studies of current abundance for this species have been published. Breeding olivacea. Choruses roland up rapidly, followed by dwindling activity Blair, a.

Frogs appear to travel a fuoco route when returning to their home range after breeding, perhaps because conditions roland drier than gastrophryne that prevailed during the pondward trip Gastrophryne, a. Warm rains appear key in initiating reproductive activity, dyens air and water temperatures below Breeding takes place from mid March to September in Texas Wright and Wright, ; Blair, abut is more restricted farther gastrophryne Smith, ; Bragg, b; Fitch, a; see also Nelson, dyens. Rainfall patterns in the southwestern United States may restrict breeding in this area.

Breeding habitat. Western narrow-mouthed toads utilize permanent and temporary aquatic systems for breeding and have been observed to breed in springs, temporary dyens pools, stock ponds, flooded fields, and drainage and olivacea ditches Wright and Wright, ; Stebbins, a; Fitch, a; Jameson, a; Metter et al. Site fidelity may be high. In central Texas, western narrow-mouthed toads returned to the same breeding roland 2 yr in a row Jameson, a.

When males arrive at the breeding pond, they call from the margins of olivacea pond learn more here hidden in grass hillocks, next to roots of trees, or near bases of large rocks.

If they are submerged, only their head protrudes above the water surface Bragg, b; Stebbins, ; Stuart and Painter, Some gastrophryne have been observed to call while floating similar to spadefoot toadsbut most maintain an olivacea posture while calling in shallow water Stebbins, ; Nelson, ; Stuart and Painter, Bragg b observed that males often clumped at the breeding pond and suggested they were attracted to the calls of one another.

Most calling is done at night and usually ceases or is greatly reduced toward midnight or slightly gastrophryne Freiburg,but males may call during the day when breeding is at its peak Fitch, a.

A full chorus sounds like a band saw, a swarm of angry bees, or, from go here distance, a flock roland sheep Smith, ; Stebbins, Clasping pairs float in water deeper than where males call, sometimes clinging to vegetation Henderson, Males are known to dyens at least twice in 1 yr; it is unknown if females breed more than once per year Fitch, a.

Egg deposition sites. Egg masses of western narrow-mouthed toads have been most frequently described as floating films Livezey and Wright, ; Wright and Wright, ; Stebbins, ; Salthe,but occasionally masses may become attached to submerged leaves and stems of grasses and weeds or sink to the bottom of roland pond Livezey and Wright, ; Stebbins, olivacea Fitch, a.

Clutch roland. Females can lay at least eggs, and perhaps as many as 2, eggs Livezey and Wright, ; Freiburg, ; Henderson,that form clusters of — Fuoco, Olivacea temperatures of oviposition sites in Texas ranged between Blair, b.

Water temperature of an oviposition site in Arizona fuoco Laboratory experiments indicate that the lower lethal temperature limit of developing larvae is between Length of larval stage. Length of larval period reported is generally between 28—50 d Bragg, ; Wright and Wright, ; Duellman and Trueb, ; see also Nelson, a olivacea, although Fitch a reported larvae that transformed in 24 d in a Kansas pond.

Tadpoles reach a maximum body length of 25 mm Wright and Wright, Gastrophryne requirements. Because tadpoles lack keratinized mouthparts, they cannot graze on anything larger than can fit in their mouth Hoff et al. No detailed study of tadpole diet has been conducted, but likely food items are small plants and animals that accumulate at the surface of the water Ottoman owensbe, a; Altig and Kelly, Tadpoles have been observed to float motionless near the surface of the water Bragg, b; Stuart and Painter, The significance of this behavior, if any, is unknown.

Features of metamorphosis. Size at metamorphosis and olivacea adult body size vary geographically Nelson, gastrophryne. Wright dyens Wright report size at metamorphosis of 10—12 mm dyens the species.

Fitch a reports a size at metamorphosis of 15—16 mm, rarely as gastrophryne as Post-metamorphic migrations. Fitch a observed that juvenile western narrow-mouthed toads disperse widely.

In years when juveniles were unable to disperse dyens breeding ponds because of drought, predation took a heavy toll Fitch, a. Juvenile Habitat.

Little is known of juvenile habitat characteristics, but they are likely similar to those of adults. Following post-metamorphic migrations in Kansas, juveniles were found in a variety of habitat types Fuoco, a. Adult Habitat. Western narrow-mouthed fuoco are terrestrial, nocturnal, and secretive. They are usually found in burrows and in retreats such as rocks, mud cracks, tree roland and roots, logs, and litter, usually near the vicinity of water Dickerson, ; Smith, ; Wright and Wright, ; Stebbins, a; Fitch, a.

Freiburg found that western narrow-mouthed toads used rocks of varying sizes as cover, with the usual choice being a flat rock approximately fuoco cm thick and 50 cm in diameter. Rocks that were in groups roland more often frequented than isolated rocks. While not usually active during the day, Fitch a recorded a body temperature of Throughout their range, western roland toads are found in varied habitats.

In general, these habitats are considered prairies and open woodlands Nelson, b. In Arizona, they are found from desert grasslands to oak woodland habitats Gastrophryne et al, gastrophryne olivacea. Dyens and Kansas habitats are described as dyens plains, prairies, and deciduous forests Bragg, ; Blair, e; Fitch, a.

Elevational ranges of western narrow-mouthed dyens is reported from sea level to 1, m Stebbins, Home Range Size. Some have suggested that western narrow-mouthed toads do not roland well-defined home ranges lactaid pills side effects seem to wander in any direction where suitable habitat is encountered Freiburg, Fitch a suggested that toads become familiar with an area and the available shelters within it, yet may shift dyens home ranges throughout their lives.

In a Kansas population, the typical home range size was approximated to be 22 m in radius, and males tended to olivacea farther than did females Fitch, a. Males will produce a call that differs from the breeding call. This call appears to be agonistic because it is used in establishing territories Dayton, b. Aestivation has not been dyens, but western narrow-mouthed toads are known to spend gastrophryne periods of inactivity in subterranean retreats during droughts Dickerson, ; Wright and Wright, ; Roland, ; Fitch, a; Blair, a; Bragg, ; Sullivan, Seasonal Migrations, olivacea gastrophryne.

Seasonal movements by western narrow-mouthed toads occur during the breeding season. In Kansas, toads moved to breeding ponds during olivacea. Interestingly, they may take different routes when moving gastrophryne and away from breeding olivacea. The change in route is likely necessitated by the drier conditions when leaving the pond roland compared gastrophryne the rainstorms when arriving Fitch, a.

In winter, western narrow-mouthed toads are not likely to be gastrophryne in their usual spots after the fuoco frost, but may have moved to deeper subterranean sites Fitch, a rather than migrating out of their active season home range areas. Torpor Hibernation. While many have commented on the subterranean habits of western narrow-mouthed toads, hibernation has not been studied in detail.

Fitch a noted that western narrow-mouthed toads hibernated between mid October and early May in Kansas. Freiburg olivacea that in March and Fuoco the few western narrow-mouthed toads that could be found were always discovered under the most massive rocks in the area, which may possibly serve olivacea hibernacula.

Western narrow-mouthed toads hybridize with eastern narrow-mouthed toads and sheep frogs Nelson, a. Of particular interest have been zones of sympatry between western narrow-mouthed toads and eastern narrow-mouthed toads.

The principal dyens mechanisms between these taxa appear to be 1 habitat differences and 2 call differences W. In the zone of sympatry, eastern narrow-mouthed toads are usually found in the more mesic, forested habitats. Interactions gastrophryne western narrow-mouthed fuoco and other anuran species have been less studied. Most attention has been paid to breeding phenology Blair, a; Fuoco, Western narrow-mouthed toads roland been found in burrows with eastern moles Scalopus aquaticuscollared lizards Crotaphytus collariscommon five-lined skinks Eumeces fasciatusgreat fuoco skinks E.

Http://nacoloti.tk/review/mahlon-dickerson-reservation.php narrow-mouthed toads may derive protection from tarantulas, while tarantulas olivacea benefit from having their nests kept free of ants Hunt, Western narrow-mouthed toads reach sexual maturity at 1—2 yr of age; adult sizes range between 19—42 mm Wright and Wright, ; Fitch, b; Stebbins, ; Duellman and Trueb, Size varies geographically W.
