Fertilization is a complex process, and gamete traits can affect the rate at which sperm and egg collide and fuse, making them prime targets for selection. This is particularly true for broadcast spawners, whose fertilization success...
The evolution of matrotrophy introduces the potential for genomic conflicts between mothers and embryos. These conflicts are hypothesized to accelerate the evolution of reproductive isolation and to influence the evolution of life...
Numerous studies of local adaptation have shown that populations can adapt quickly to local environmental conditions. Other studies have shown that sister species tend to occur in different environments. Recent work has gone a long way...
A central question of evolutionary biology concerns the study of evolvability. A growing body of theory implicates the pattern of genetic effect interactions underlying a trait, referred to as the genetic architecture of a trait, as an...
The nest architecture of underground ant nests was studied in Formica pallidefulva. These ants build shallow (30-45 cm deep) nests, which consisted of more or less vertical shafts that bear chambers. Shafts appeared to be modular units...
When the two sexes maximize their fitness in different ways, a sexual conflict emerges, in which traits favored in one sex are not favored in the other (Parker 1979, Arnqvist and Rowe 2005). Under interlocus sexual conflict, a type of...
The fields of community ecology and evolution are theoretically tightly linked, but in general, community ecologists discount evolution in describing the dynamics of present-day community patterns. Yet, evolution in response to strong...
The persistence of mixed mating systems in plants, in spite of theory suggesting that either complete outcrossing or selfing should evolve depending on the level of inbreeding depression, has become a classic puzzle in evolutionary...
Quantitative genetics is a powerful tool for predicting phenotypic evolution on a microevolutionary scale. This predictive power primarily comes from the Lande equation (Δz̅=Gβ), a multivariate expansion of the breeder's equation, where...
The use of an alternative male mating tactic is frequently discussed as an option that makes the best of a bad situation for disadvantaged males and not as part of an adaptive system that can produce equal average levels of reproductive...
Characterizing Non-Typical Epithelial Behavior: Analysis of the Spatiotemporal Patterns of Patency, and a Study of Nonautonomous Cellular Compaction in Drosophila Melanogaster Follicular Epithelium
The follicular epithelium (FE) in the Drosophila melanogaster ovary is an excellent model system to study epithelial processes and behaviors, such as cell-cell communication, cell cycle regulation, and epithelial morphogenesis. The...
While theory shows that the distribution of populations in space can have profound ecological and evolutionary consequences, the complexity of numerical and genetical dynamics in space has made evaluation of model assumptions and...
Predicting which species will become invasive when introduced to a novel range is one of the main goals of invasion biology. However, many studies of the factors influencing invasion either use the wrong comparison group, fail to control...
In many animal species there is pronounced and repeatable variation among individuals in their expression of suites of behaviors, resulting in consistent behavioral types. These behavioral types are characterized by measures like the...
Many venom proteins have presumably been convergently recruited by taxa from diverse venomous lineages. These toxic proteins have characteristics that allow them to remain stable in solution and have a high propensity for toxic effects...
