Morphogentic studies of intraspecific hybrids of Microseris laciniata (Hook.) Sch.-Bip.

Creator:

Pires, Maria Joaquina Pinheiro

Abstract:

Microseris laciniata is a perennial, self-incompatible species classified in subgenus Scorzonella. It is morphologically the least specialized species in the genus, in contrast to the members of subgenus Microseris, which are morphologically advanced, self-compatible annuals. First-generation hybrids were available from crosses involving eight populations of two subspecies of Microseris laciniata...

Abstract:

Studies of consumer-resource interactions suggest that individual diet specialisation is empirically widespread and theoretically important to the organisation and dynamics of populations and communities. We used weighted networks to analyze the resource use by sea otters, testing three alternative models for how individual diet specialisation may arise. As expected, individual...
