PP2A:B56epsilon is required for eye induction and eye field separation.

Eye induction and eye field separation are the earliest events during vertebrate eye development. Both of these processes occur much earlier than the formation of optic vesicles. The insulin-like growth factor (IGF) pathway appears to be essential for eye induction, yet it remains unclear how IGF downstream pathways are involved in eye induction.

Carrion fly (Diptera: Calliphoridae) larval colonization of sunlit and shaded pig carcasses in West Virginia, USA.

Two pig (Sus scrofta L.) carcasses were placed in sunlit and shaded plots in September 2003, and again in May 2004. Mean ambient temperatures between sunlit and shaded plots were not significantly different in either September or May, but mean ambient temperatures at sunlit and shaded plots in 2004 were significantly higher than corresponding means for sunlit and shaded plots in 2003.
