Hybridization in Ants
<p>Interspecific hybridization is a relatively common occurrence within all animal groups. Two main factors make hybridization act differently in ants than in other species: eusociality and haplodiploidy. These factors serve to reduce the costs of interspecific hybridization in ants while …

Plasmon hybridization in real metals
… incompressible and irrotational fluid, Plasmon hybridization (PH) method can be used as a very useful tool in interpolating the electric magnetic behaviors of complex metallic nanostructures. Using PH theory and Finite Element Method (FENI), we theoretically investigated the optical properties …

Experimental designs for population hybridization studies
… designs were developed for population hybridization studies. The objective of all of these designs was to obtain information about (i) the general combining ability of populations, (ii) the specific combining ability of population crosses, (iii) the general combining ability of …

Meta-RaPS Hybridization with Machine Learning Algorithms
… framework (or AMP) and the metaheuristic hybridization taxonomy. The concepts from both frameworks are followed when identifying useful information that Meta-RaPS can collect during execution. Hybridizing Meta-RaPS with machine learning algorithms helped in transforming the collected …

Evolutionary history and hybridization in Passerina buntings
Understanding the genetic basis of speciation is of fundamental importance to evolutionary biology and hybrid zones offer unique natural laboratories in which to investigate the ecological and evolutionary processes important in creating and maintaining biological diversity. By comparing …

Hybridization Between Amaranthus Tuberculatus and Amaranthus Hybridus
Interspecific hybridization can be thought of as a potential adaptive mechanism by which favorable alleles may be transferred among related species. Studies have shown that weedy Amaranthus species are capable of interspecific hybridization, and hybridization may foster the evolution of herbicide …

Adaptation and hybridization in Helicoverpa crop pests
… reproductive isolation. As a consequence of hybridization, an allele conferring insecticide resistance was introduced into the native Brazilian H. zea population through adaptive introgression. I use this as a system with which to investigate the outcome of secondary contact between native …

Inter-specific hybridization in the fish family Cyprinidae
… reproductive isolation leading to inter-specific hybridization is a widespread phenomenon amongst cyprinid fishes. There are seventeen cyprinid species occcurring in the British Isles, within five sub-families, giving rise to some ten different types of hybrid. Most of these belong to the …

The Evolutionary Causes and Consequences of Mammalian Hybridization
… the wild to study the causes and consequences of hybridization in mammals. Hybrid sterility is a common reproductive barrier between species that tends to preferentially manifest in the heterogametic sex and frequently genetically maps to the sex chromosomes. Thus, the sex chromosomes appear to …

DNA Hybridization and Ligation for Directed Colloidal Assembly
… centrifugation. The salt requirement for DNA hybridization and ligation made it necessary to use slow salt addition through a dialysis membrane to achieve well-ordered colloidal crystals. Well-ordered hexagonally close-packed polystyrene colloid monolayers could be assembled by sedimentation, …

Merge : the hybridization of architecture, infrastructure, and landscape
… What generative forms and spaces emerge through hybridization? This thesis investigation seeks to understand at what scales this hybridization can occur, from the urban scale of infrastructure to the architectural scale of building form and building identity.

Analysis of Hybridization Between Native and Invasive Pupfishes (Cyprinodon)
… are detrimental to native species and when hybridization is involved a decrease in biodiversity may result. <em>Cyprinodon variegatus </em>is an invasive species that has caused devastation to several <em>Cyprinodon </em>species through rapid hybridization and genetic introgression. …
