Morphological Detection of Genetic Introgression in Red Junglefowl (Gallus Gallus)
… status. However, evidence suggests that genetic introgression from free-ranging, escaped, and feral domestic chickens might be so widespread and pervasive that Red Junglefowl may be endangered or even extinct in the wild. Because genetic markers have yet to be identified, detection of …

Effects of selective genetic introgression from wild soybean to soybean
… in the U.S. currently relies on a narrow genetic base in which more than half of the genetic contribution, calculated by pedigree analysis, comes from only 5 ancestral lines. For decades, but more intensely in recent years, efforts have been made to incorporate exotic soybean germplasm …

Genetic introgression and female mate choice within the Calendulauda albescens/C. barlowi hybrid zone
… of these individuals to determine if possible introgression is occuring from C. albescens to C. barlowi. Mitochondrial DNA from 13 lark individuals found in the C. albescens/C. barlowi hybrid zone was analysed. A 358 base pair cytochrome-b sequence was obtained. The neighbour-joining …

Morphological Variation and Community Science in Orthoptera
… for a subset of crickets demonstrating nuclear genetic introgression, phenotypic intermediacy of hybrids, and essentially unidirectional mitochondrial introgression. We discuss how these morphological traits relate to life history differences between the species. Our comparisons across …

Analysis of Hybridization Between Native and Invasive Pupfishes (Cyprinodon)
… </em>species through rapid hybridization and genetic introgression. <em>Cyprinodon rubrofluviatilis </em>is native to the Brazos, Wichita and Red Rivers but<em> </em>fish collected between 2006-2012 from the Brazos River expressed intermediate morphological traits suggesting hybridization had …

MOLECULAR AND MORPHOLOGICAL CONSEQUENCES OF POST-GLACIAL CONTACT AMONG LINEAGES OF NORTHERN SHORT-TAILED SHREWS (Blarina brevicauda) IN EASTERN NORTH AMERICA
… the contact zones where they meet. Using a genetic and morphological approach, I evaluated evidence for hybridization between historically isolated phylogroups of <em>B. brevicauda</em> by quantifying the distribution of genetic and morphological variation within and across contact zones. …

Utilization of Stormwater Retention Ponds by Aquatic Turtles in Montgomery County, Virginia

Evolutionary dynamics of bird populations in Southeast Asia
… factors that shaped the morphological and genetic diversity of rainforest birds in Southeast Asia. (1) In the Oriental Dwarf Kingfisher (Ceyx erithaca) complex, the birds are highly polymorphic in plumage. Quantitative analysis of this variation indicated that a large proportion of birds in …
