Provost Lecture Series: Tangled taxonomy for the genus

10/28/2011

Clarifying a tangled taxonomy for a genus is the focus of the next Provost Lecture Series at Austin Peay State University.

Dr. Dan Frederick, professor of geology and geography, will present “The Foraminiferal Genus Lenticulina: Revising a tangled taxonomy” from 3-4:30 p.m., Thursday, Nov. 3 in the Morgan University Center, Room 307. All presentations in the Provost Lecture Series are free and open to the public.

The genus Lenticulina (Lamarck) has a long a complex history with numerous name changes and definitions.  In addition, many often poorly defined species have been assigned to the genus. The result is a confusing mass of names and variations, complicating any attempt to understand the evolutionary history of the genus and the interplay between morphologic variation, abundance and evolution. 

Frederick’s research has several interrelated goals: to clarify the definition of the genus and the number of species within it, to discuss the degree of variation of both morphology and abundance in this long-ranging taxon and to examine the relationships between variation, species duration and environment in shaping the evolutionary history of the genus Lenticulina

The Provost Lecture Series seeks to foster a spirit of intellectual and scholarly inquiry among faculty, staff and students. The program will be used as a platform for APSU faculty members who are recent recipients of provost summer grants, who have been awarded faculty development leaves and who have engaged in recent scholarly inquiry during sabbatical leaves.

APSU faculty members with recent research of acclaim also will be given a platform within this series. In addition, other faculty members of local or widespread renown will be invited to lecture within this series.
