Forms and prevalence of intersexuality and effects of environmental contaminants on sexuality in cricket frogs
Six species called across these surveys: Northern Cricket Frogs
(Acris crepitans), Gulf Coast Toads (Incilius nebulifer), Cliff Chirping Frogs (Eleutherodaclylus marnockii), Spotted Chorus Frogs (Pseudacris clarkii), American Bullfrogs (Lithobates calesbeianus), and Rio Grande Leopard Frogs (Lilhobates berlandieri).
Blanchard's Cricket Frog
(Acris blanchardi) --Cricket Frogs
were frequently encountered in the wooded sinkhole surrounding Stemler Cave and rarely within the entrance.
Blanchard's cricket frogs
(Acris blanchardi) are small (15-38 mm snout-vent length [SVL]) anurans active from February to November in Kansas, with a peak in breeding occurring from mid-May to late June (Collins et al.
We would see northern cricket frogs
frequently: at lakes, marshes and swamps in summer, and in deep woods and dry ridge lines in spring and fall.
A similar species, Myxidium melleni Jirku, Block, Whipps, Janovy, Kent & Modry, 2006 was described from western chorus frogs (Pseudacris triseriata) and Blanchard's cricket frogs
(Acris blanchardi) from Nebraska (Jirku et al.
7% of cricket frogs
collected in Illinois in 1993, 1994, and 1995 were intersex individuals (1998).
and other amphibians are therefore valuable sentinels of ecologic change.
We observed cricket frogs
in a variety of habitats: flooded agricultural fields, retaining ponds, mitigation wetlands, and farm ponds.
have virtually disappeared from northern Iowa (Hemesath 1998), northeastern Illinois (Mierzwa 1998), northern Indiana (Brodman and Kilmurray 1998; Minton 1998), and northern Wisconsin (Casper 1998; Mossman and others 1998).
We're seeing an increase in wildlife numbers and diversity at these wetlands and reservoirs--everything from deer and raccoons to birds and frogs, including an increase in numbers of Blanchard cricket frogs
, which were thought to be endangered.
He follows the clicking of the cricket frogs
, which gradually grows louder.
