Understanding the reasons why intraspecific diversity arises and how populations adapt to spatial variation in environmental conditions continues to be a major focus of evolutionary biology. Recently, inversion polymorphisms have become an active area of research focused on unde…

The Nile crocodile Crocodylus niloticus currently has an extensive range throughout the African continent and Madagascar, though fossil and subfossil remains show that its historic range was considerably larger and included parts of the Sahara Desert, Mediterranean coast, and Ar…
The present study represents the first major effort toward establishing a ceramic sequence of the Iron Age II strata at Tel Ashkelon, Israel. A morphometric methodology is developed and used for the classification of the representative rim-forms of the assemblages from Phases 16…
Two experiments were performed with live turkeys to investigate the nature of adaptive bone remodeling, i.e., the relationship between bone strains and bone morphology. Three birds were trained to hop on one leg during short sessions while otherwise walking normally; the exercis…
The performance of hybrid progeny of outcrossing parents for a variety of important agronomic traits can be highly variable and differ substantially from the performance of either parent. Luxury commodities, such as strawberry, more than staples, have to find that balance been f…
The North American river otter is a semiaquatic carnivore that occupies freshwater habitats across most of North America, and is a conservation symbol across most of its range. It is used as an indicator species, a keystone species, an umbrella species, and an example of conserv…
Contemporary species are undergoing population declines and extinction at rates unprecedented in recorded history. These ongoing global biodiversity losses are largely caused by human overpopulation and other anthropogenic impacts on the environment such as natural habitat destr…
Chapter 1 is a literature review of the taxonomic history of Clematis subg. Viorna. Chapter 2 is a morphometric study and taxonomic treatment of the Clematis reticulata species complex. Clematis subgenus Viorna of North America currently consists of 21 species, most of which are…
