The first host includes a number of species of aquatic snails. The early larval stages of the trematodes then are transmitted into aquatic tadpoles, where the metacercariae (larvae) encyst in developing limb buds.

Because they have no natural predators in Hawaii, populations of coqui frogs in Hawaii can reach densities of up to 91, 000 frogs per hectare, according to DLNR, two to three times higher than ...
The researchers recorded pattern morphs for 9,950 frogs captured at nine locations over a 25-year period. The data revealed 21 distinct pattern morphs, including stripes, bars, and spots. Significant differences in morph frequencies were observed among locations, with longitudinal stripes more common in grassland , and spot and bar morphs more ...

[ 5 ] [ 6 ] [ 2 ] [ 7 ] In 2016, a consortium of Rana researchers from throughout Europe, Asia, and North America revised the group, and reported that the ...
PEP’s 6.5% five-year annualized dividend growth rate is nearly twice that of KO’s 3.1%. The growth trajectory of each company plays a huge factor in determining which is the more desirable ...
