Males perceive honest information from female released sex pheromone in a moth

Yiftach Golov, Adrea Gonzalez-Karlsson, Russell Jurenka & Allly Harari
There is accumulating evidence that male insects advertise their quality to conspecific females through pheromones. However, most studies of female released sex pheromone assume information transfer regarding merely the species of the female and her mating status. We show that more and precise information is conveyed through the female sex pheromone, positioning it as an honest sexual trait. We demonstrate that females in bad physical conditions (small, starved or old) lay significantly fewer eggs than...

Establishing the role of light intensity as a factor for disease forecasting systems

Suzanne Slack
This is an ARDP applied research (single-function) project with a request of $301,732 funds. The use of antibiotics and biologically derived pesticides (biopesticides) are essential to producing high quality specialty crops. With biopesticides are becoming more widely adapted, best application timings for integrative disease forecasting systems need updated. For fire blight, the disease models only use streptomycin data, which outperforms other registered antibiotics and biopesticides. A study by the grant submitters found that the major...

Chimpanzees as ecosystem service providers: Seed dispersal of an economically important plant resource

William Aguado, Haldre Rogers & Jill Pruetz
Vertebrate-mediated seed dispersal is vital to the maintenance of diversity in tropical ecosystems, and seed-dispersing animals are increasingly thought to provide ecosystem services by dispersing the seeds of plant species utilized by people. However, few studies have demonstrated a link between vertebrate frugivores and plants used by people, thus limiting the generalizability of the seed-disperser-as-ecosystem-service-provider concept. We examined the effectiveness of western chimpanzees (Pan troglodytes verus) as seed dispersers (i.e., their influence on seedling recruitment)...

Influence of habitat quality and resource density on breeding-season female monarch butterfly (Danaus plexippus) movement and space use in north-central USA agroecosystem landscapes

Kelsey Fisher & Steven Bradbury
The eastern North American monarch butterfly is at risk of quasi-extinction due, in part, to the loss of breeding habitat in agricultural landscapes of the USA Midwest. Because adult females are not patch residents, egg abundance and distribution across the landscape are a function of their perceptual range, flight directionality, and flight step lengths. Conservation actions that account for habitat use in agricultural landscapes can enhance functional connectivity. Field-captured females (n=114) were released in a...

Demonstration of local adaptation in maize landraces by reciprocal transplantation

Garrett Janzen, Maria Rocio Aguilar-Rangel, Carolina Cintora-Martinez, Karla Azucena Blocher-Juarez, Eric Gonzalez-Segovia, Anthony Studer, Daniel Runcie, Sherry Flint-Garcia, Ruben Rellan-Alvarez, Ruairidh Sawers & Matthew Hufford
Populations are locally adapted when they exhibit higher fitness than foreign populations in their native habitat. Maize landrace adaptations to highland and lowland conditions are of interest to researchers and breeders. To determine the prevalence and strength of local adaptation in maize landraces, we performed a reciprocal transplant experiment across an elevational gradient in Mexico. We grew 120 landraces, grouped into four populations (Mexican Highland, Mexican Lowland, South American Highland, South American Lowland), in Mexican...

Frei Otto's Pneumatic Experiments for Humanitarian Design

This paper will explore the intersection of building technology and humanitarian design-science research by looking at Frei Otto’s pneumatic experiments. The purpose of the study is to contextualize our contemporary demands for humanitarian design work by reflecting upon the manner by which Otto integrated an ambitious design ideology with an elevated and innovative technical acumen. Constraining the investigation to Otto’s work, particularly his relatively unknown early work with pneus, provides a useful exploration of design-science...

Sheepnose mussel (P. cyphyus) microsatellite dataset for population genetic analysis

Sara Schwarz & Kevin Roe
North American freshwater mussel species have experienced substantial range fragmentation and population reductions. These impacts have the potential to reduce genetic connectivity among populations and increase the risk of losing genetic diversity. Thirteen microsatellite loci and an 883 bp fragment of the mitochondrial ND1 gene were used to assess genetic diversity, population structure, contemporary migration rates, and population size changes across the range of the Sheepnose mussel (Plethobasus cyphyus). Population structure analyses reveal five populations,...

Genome-wide sequence data show no evidence of hybridization and introgression among pollinator wasps associated with a community of Panamanian strangler figs

Jordan Satler, Allen Herre, Tracy Heath, Carlos Machado, Adalberto Gomez & John Nason
The specificity of pollinator host choice influences opportunities for reproductive isolation in their host plants. Similarly, host plants can influence opportunities for reproductive isolation in their pollinators. For example, in the fig and fig wasp mutualism, offspring of fig pollinator wasps mate inside the inflorescence that the mothers pollinate. Although often host specific, multiple fig pollinator species are sometimes associated with the same fig species, potentially enabling hybridization between wasp species. Here we study the...
