Accounting for Additional Heterogeneity: A Theoretic Extension of an Extant Economic Model
<p>The assumption in economics of a representative agent is often made. However, it is a very rigid assumption. Hall and Jones (2004b) presented an economic model that essentially provided for a representative agent for each age group in determining the group's health level function. Our work seeks …

The Phylogenetic Relationships Among Extant Catfishes, With Special Reference to Ictaluridae (Otophysi: Siluriformes)
Cytochrome b suggested cryptic diversity within several species of Noturus. Relationships among members of the subgenus Rabida were resolved and in many cases well supported. Relationships among Schilbeodes were poorly resolved. A calibrated substitution rate identified a period between 8 and 2 …

Palaeobiology and flight capacity of volant palaeognaths (Pan-Palaeognathae: Lithornithidae): implications for the common ancestor of extant palaeognaths and early crown birds
Extant palaeognathous bird diversity comprises the flightless ratites (ostriches, rhea, kiwi, cassowaries, and emu), as well as the partridge-like tinamous that fly powerfully over short distances. As the sister clade of all other crown birds (Neognathae), insight into the biology of early …

Dead bugs do tell tales: implications of a new fossil assassin bug (Heteroptera: Reduviidae) for the evolutionary history and systematics of an extant lineage
The following thesis comprises three parts: (1) the description of a new fossil assassin bug, (2) the use of this newly described taxon to inform the phylogenetic history of the family, and (3) a survey of previously-described extinct taxa compiled into the first taxonomic catalog of fossil …

Studies on the evolution of morphological traits in ferns, with an emphasis on the family Dipteridaceae.
Extant ferns form a diverse, monophyletic group that is sister to the seed plants. Although ferns are rarely the dominant feature of any particular flora, they are found in many of the same habitats that seed plants occupy today. Studying the evolution of characters within this separate line of …
