| a new species of eimeria (apicomplexa: eimeriidae) from the marbled salamander, ambystoma opacum (caudata: ambystomatidae), from northern louisiana. | between december 2002 and june 2004, 10 marbled salamanders, ambystoma opacum, were examined for coccidian parasites. salamanders were collected in bradley (n = 2), little river (n = 1), miller (n = 1), and sevier (n = 1) counties, arkansas; webster parish, louisiana (n = 2); and bowie (n = 1) and nacogdoches (n = 2) counties, texas. two of 10 (20%) a. opacum from louisiana harbored an undescribed species of eimeria. oocysts of eimeria trauthi n. sp. were ellipsoidal, 36.6 x 33.1 (33-40 x 29-37) ... | 2008 | 18605797 |
| effect of acute low body temperature on predatory behavior and prey-capture efficiency in a plethodontid salamander. | the low-temperature limit for feeding in some salamander species (desmognathus, plethodontidae) has been inferred from field studies of seasonal variation in salamander activity and gut contents, which could not determine whether feeding is more dependent on environmental conditions influencing salamander foraging behavior or prey availability and movement. we performed two controlled laboratory experiments to examine the effect of short-term (acute) low body temperature on predatory behavior an ... | 2016 | 26939728 |
