Female mating with multiple males within a single fertile period is common phenomenon in the animal kingdom. insects are particularly promiscuous. It not clear why females mate partners despite several potential costs, such as expenditure of time and energy, reduced lifespan, risk predation contracting sexually transmitted diseases. red flour beetles (Tribolium castaneum) obtain sufficient sperm from insemination to retain fertility for months. Nonetheless they copulate repeatedly minutes...

Information on the molecular basis of resistance and evolution is crucial to an understanding appearance, spread, distribution genes mechanisms host adaptation in natural populations. One potential important genetic constraint for fitness cost associated with resistance. To determine whether parasite infection costs, we conducted simultaneous quantitative trait loci (QTL) mapping traits using red flour beetle (Tribolium castaneum) tapeworm (Hymenolepis diminuta) system two independent...
The costs of mating with multiple partners include expenditure energy and time a reduction in lifespan, but females many taxa mate several different shortly after their first copulation. Often it is not clear what gain from this behaviour. In study, we used the red flour beetle (Tribolium castaneum Herbst, 1797) to test hypothesis that males for fertility assurance because copulation often does lead offspring production. We found probability producing offspring, as measured by proportion...
Best-practices pedagogy in science, technology, engineering, and mathematics (STEM) aims for inclusive excellence that fosters student persistence. This paper describes principles of inclusivity across 11 primarily undergraduate institutions designated as Capstone Awardees Howard Hughes Medical Institute's (HHMI) 2012 competition. The Capstones represent a range institutional missions, profiles, geographical locations. Each successfully directed activities toward persistence STEM students,...
Many female insects mate with multiple males within a single fertile period despite costs such as expenditure of energy and time contraction sexually transmitted diseases. In the red flour beetle, Tribolium castaneum, females remate different minutes first copulation. If rapid mating is adaptive then multiply mated should have higher fitness than singly females. this study, we determined remating frequency beetles, characterized behavior, examined consequences mating. We found that T....
The use of transgenic mosquitoes with parasite inhibiting genes has been proposed as an integral strategy to control malaria transmission. However, release exotic will bring in novel alleles along parasite-inhibiting that may have unknown effects on native populations. Thus it is necessary study the and dynamics fitness traits mosquito populations response introduction genes. This was designed evaluate a simulation under laboratory conditions using two strains Anopheles gambiae: Mbita strain...
Abstract Polyandry or female mating with several different partners in a single fertile period is widespread phenomenon possibly involving both costs and benefits. This study tested whether remating after weeks of initial copulation (periodic multiple mating) has fitness consequences for females red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), cosmopolitan storage pest. We hypothesize that benefit from higher frequency more mates through sperm replenishment and/or...
Parasites may exert negative effects on host survivorship and reproductive success. The of parasites female fitness have been well documented; however, the success male hosts particularly underlying mechanisms that alter are not understood. Previous studies demonstrated infection by rat tapeworm (Hymenolepis diminuta) reduced red flour beetles (Tribolium castaneum) in an environment mate choice strong male-male competition. present study determined role insemination capacity observed...
Abstract Female mate choice, both before and after copulation, is pervasive among insect species. It often hypothesized that females would preferentially with males are genetically dissimilar to promote the genetic variability of offspring. We used various strains red flour beetle, Tribolium castaneum, tested effect male female backgrounds on precopulatory post-copulatory choice. Simultaneous choice experiments using previously well established pheromone assays did not detect preference for...
Abstract Parasites have profound effects on host ecology and evolution, the of parasites are often influenced by magnitude susceptibility to parasites. Many complex life cycles that require intermediate hosts for their transmission, but little is known about genetic basis host's these This study examined a tapeworm (Hymenolepis diminuta) in red flour beetle (Tribolium castaneum) serves as an its transmission. Quantitative trait loci (QTL) mapping experiments were conducted with two...
We adopted Facebook as part of a large enrollment science discussion class in bid to exploit students’ time on this social networking site and tested the effectiveness “co-option” strategy creating education-related activity for our students. used “Facebook Group” create an online avenue scientific claim students wished evaluate by inviting them post comment articles. found that with respect extent participation well diverse ways use, group surpassed expectations set instructors.

Abstract Parasite infection impacts population dynamics through effects on fitness and fecundity of the individual host. In addition to known roles environmental factors, host susceptibility parasites has a genetic basis that not been well characterized. We previously mapped quantitative trait loci (QTL) for rat tapeworm (Hymenolepis diminuta) in Tribolium castaneum using dominant AFLP markers; however, resistance genes were identified. Here, we refined QTL locations increased marker density...
This case study reports the instructional development, impact, and lessons learned regarding use of Facebook as an educational tool within a large enrollment Biology class at Spelman College (Atlanta, GA). We describe this social networking site to (a) engage students in active scientific discussions, (b) build community student body class, (c) promote communication between instructors. To achieve this, we created Group page that were required join complete main assignment which was read,...
Anopheles gambiae is a major malaria vector in Africa and popular model species for variety of ecological, evolutionary, genetic studies on control. Genetic manipulation mosquito vectorial capacity promising new weapon the control malaria. However, release exotic transgenic mosquitoes will bring novel alleles addition to parasite-inhibiting genes, which may have unknown effects local population. Therefore, it necessary develop methodologies that can be used evaluate spread rate introduced...
Abstract We isolated and characterized microsatellite markers for the red flour beetle Tribolium castaneum , an important model species studies in various areas of evolutionary biology ecology. A microsatellite‐enriched genomic library was constructed screened with single stranded oligonucleotide probes [(CCT) 17 (AAT) (CAG) ]. Forty‐five primer pairs were designed which 19 produced successful amplification. Polymorphism screening involved beetles from five strains revealed 15 polymorphic...
