Previous studies on ranid
tadpoles have found predator-naive tadpoles exhibit an acute stress response upon predator exposure that is mediated by a reduction in the whole-body concentration of a stress hormone, corticosterone (Middlemis Maher et al., 2013).
Murphy and others (2006) and Papoulias and others (2013) both found that atrazine concentrations were not significantly associated with hermaphroditism in ranid
frogs, but that testicular oocyte incidence was significantly greater in juvenile frogs collected from agricultural sites versus non-agricultural sites.
insignis worms, it seems probable that natural Dracunculus infections are not limited to frogs of the genus Phrynobatrachus but may well include numerous other ranids
and highly aquatic Xenopus species frogs (African clawed frogs), which are common and native to Chad.
However, our recent study revealed the presence of two subtypes of AQP6vs (type 1 (AQPa2S, type a) and type 2 (AQPa2S, type b)) in these Ranid
species (Finn et al., 2014; Saitoh et al., 2014) (Table 1).
Leopard frogs and wood frogs are the earliest breeding ranids
at Dave's Pond, followed by the crawfish frog, with green frog and bullfrog breeding significantly later.

The distribution of these ranid
frogs is documented in older literature but Nanorana vicina has recently been re-discovered after 130 years since its initial description (Baig, 2002).

Species infected with Bd covered a wide phylogenetic range including four species of plethodontid (lungless) salamanders, three species of toads, five hylid frogs (or "tree frogs"), and four ranid
frogs (or "true frogs").
One study showed that atrazine has similar effects on the nervous system of Ranid
frogs (Papaefthimiou et al.
This study investigated wild populations of ranid
frogs across the state of Illinois to determine their susceptibility of contracting WNV.
