Food choice from endemic North Carolina tree species by captive prosimians (Lemur fulvus)

Public school choice and integration evidence from Durham, North Carolina.

Using evidence from Durham, North Carolina, we examine the impact of school choice programs on racial and class-based segregation across schools. Reasonable assumptions about the distribution of preferences over race, class, and school characteristics suggest that the segregating choices of students from advantaged backgrounds are likely to outweigh any integrating choices by disadvantaged stud...

Perceptions Held by Community College Computer Instructors in North Carolina

Community college computer instructors provide a valuable service by preparing students for challenging careers. At the same time, they face many challenges to stay current in their field and to maintain industry certifications. Therefore, community college administrators need to determine what perceptions are held by computer instructors, address any negative perceptions, and determine if inst...

Food procurement and tooth use in two sympatric lemur species.

This study of two lemur species (Lemur catta and Propithecus v. verreauxi) in Madagascar combines observations of food procurement and initial food placement in the mouth with comparisons to food toughness and external properties. Food toughness was hypothesized to play a decisive role in determining food placement during ingestion. It was found that tougher foods are generally ingested on the ...

Intraspecific chromosome variability in a lemur from the north of Madagascar: Lepilemur septentrionalis, species nova.

A cytogenetical study of 25 Lepilemur from the north of Madagascar has given evidence for six karyotypes (with four diploid numbers). Four of the karyotypes with these diploid numbers--2N = 38, 2N = 36, 2N = 34--we believe evolved from one another by centric fusion; and two karyotypes resulted from the hybridization of two of these (2N = 37 and 2N = 35). The different karyotypes distinguish the...
