Implication of Cytoplasmic Factors in the Lethality of Bufonidae Nucleocytoplasmic Hybrids [PDF]
Development, Growth & Differentiation, 1984 The nucleocytoplasmic hybrid combination performed by nuclear graft between B. bufo nucleus and B. calamita egg is 95% lethal during gastrulation mostly at the young gastrula stage (75%) and to a lesser extent at the yolk plug stage (20%). The heterologous B. calamita cytoplasm was treated or fractioned by different techniques including centrifugation,

Ecology and Evolution, Volume 16, Issue 1, January 2026.The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),
