A Preliminary Study Of The Diversity And Temporal Patterns Of Abundance Of Tachinidae In Southwestern Ohio, Diego J. Inclán, John O. Stireman Iii
A Preliminary Study Of The Diversity And Temporal Patterns Of Abundance Of Tachinidae In Southwestern Ohio, Diego J. Inclán, John O. Stireman Iii
Biological Sciences Faculty Publications
Although tachinids are one of the most diverse families of Diptera (Irwin et al. 2003) and represent the largest group of non-hymenopteran parasitoids (Belshaw 1994), the ecology of most species in the family is poorly known. Most of the studies that have focused on tachinids are related to taxonomic descriptions. Currently, our knowledge is very limited in terms of the diversity and distribution of populations across time and space, especially in the Nearctic and Neotropical Regions (Stireman 2008). There have been a number of recent studies focused on diversity and temporal distributions of tachinids in the Palaearctic Region such as …

Here we describe the immature stages and ecological associations of Antirrhea adoptiva porphyrosticta Watkins, 1928 (Lepidoptera:Nymphalidae:Morphinae). The cloud forest bamboo, Chusquea scandens Kunth (Bambusoidea: Poaceae), serves as the larval food plant for this butterfly in eastern Ecuador, the first hostplant record for Antirrhea outside the family Arecaceae. The larvae of A. adoptiva porphyrosticta are superficially similar to those of other Antirrhea species. We also provide observations on adult and larval behavior. Caterpillars of this butterfly species are parasitized by tachinid flies, as well as by Ichneumonidae and a newly described braconid wasp.

Most of the unknown biological diversity of macro-organisms remaining to be discovered and described lies in the tropical regions of the world and consists primarily of insects. Those insects with parasitoid lifestyles constitute a significant portion of insect diversity, yet parasitoids are among the most poorly known of major insect guilds in the humid tropics. Here we describe and analyze the richness of one diverse taxon of parasitoids, flies in the family Tachinidae, reared from Lepidoptera as part of a biological survey of Lepidoptera and their parasitoids in one mid-elevation (2000 m) area in the northeast Ecuadorian Andes. One hundred …
Habitat Variation Among Aquatic Gastropod Assemblages Of Indiana, U.S.A., Mark Pyron, Jayson Beugly, Matthew Spielman, Jennifer Pritchett, Stephen J. Jacquemin
Habitat Variation Among Aquatic Gastropod Assemblages Of Indiana, U.S.A., Mark Pyron, Jayson Beugly, Matthew Spielman, Jennifer Pritchett, Stephen J. Jacquemin
Biological Sciences Faculty Publications
We collected aquatic gastropods at 137 sites in lakes and streams of Indiana and tested for patterns of assemblages with environmental variables. The survey resulted in 32 species with a mean of 2.8 species at each site, and a mean abundance at each site of 144 individuals. Nonmetric multidimensional scaling (NMS) multivariate analyses resulted in watershed drainage area, water conductivity, substrate category frequency, and dissolved oxygen as significant correlates of gastropod assemblage structure. Gastropod assemblages of lakes were not significantly different than assemblages of streams in the ordination. Prosobranch taxa occurred in higher abundances than pulmonate taxa at sites with …

Shifts In Southern Wisconsin Forest Canopy And Understory Richness, Composition, And Heterogeneity, David A. Rogers, Thomas P. Rooney, Daniel Olson, Donald M. Waller
Shifts In Southern Wisconsin Forest Canopy And Understory Richness, Composition, And Heterogeneity, David A. Rogers, Thomas P. Rooney, Daniel Olson, Donald M. Waller
Biological Sciences Faculty Publications
We resurveyed the under- and overstory species composition of 94 upland forest stands in southern Wisconsin in 2002–2004 to assess shifts in canopy and understory richness, composition, and heterogeneity relative to the original surveys in 1949–1950. The canopy has shifted from mostly oaks (Quercus spp.) toward more mesic and shade-tolerant trees (primarily Acer spp.). Oak-dominated early-successional stands and those on coarse, nutrient-poor soils changed the most in canopy composition. Understories at most sites (80%) lost native species, with mean species density declining 25% at the 1-m2 scale and 23.1% at the 20-m2 scale. Woody species have increased …
Tachinid Collecting In Southwest New Mexico And Arizona During The 2007 Nads Field Meeting, John O. Stireman Iii
Tachinid Collecting In Southwest New Mexico And Arizona During The 2007 Nads Field Meeting, John O. Stireman Iii
Biological Sciences Faculty Publications
The 2007 field meeting of the North American Dipterists Society (NADS) was held August 13–16 in southwestern New Mexico, centered in Silver City (at Western New Mexico University), and the surrounding Gila National Forest. This was the first NADS meeting that I have been able to attend, and I think I can speak for all in saying it was enjoyable, productive, and interesting; an overall success. A more detailed account and evaluation of this meeting is available in the 2007 Fly Times article (O’Hara 2007).

To determine whether the distinctive features of Caenorhabditis elegans chromosomal organization are shared with the C. briggsae genome, we constructed a single nucleotide polymorphism-based genetic map to order and orient the whole genome shotgun assembly along the six C. briggsae chromosomes. Although these species are of the same genus, their most recent common ancestor existed 80-110 million years ago, and thus they are more evolutionarily distant than, for example, human and mouse. We found that, like C. elegans chromosomes, C. briggsae chromosomes exhibit high levels of recombination on the arms along with higher repeat density, a higher fraction of intronic …

Preliminary Notes On Tachinidae Reared From Lepidoptera In The Ecuadorian Andes, John O. Stireman Iii
Preliminary Notes On Tachinidae Reared From Lepidoptera In The Ecuadorian Andes, John O. Stireman Iii
Biological Sciences Faculty Publications
Current estimates of the species richness of Tachinidae among geographical provinces suggest that the Neotropical Region harbors the largest number of species and represents a geographic epicenter of tachinid diversification (O’Hara 2006). The Neotropics boasts an impressive fauna consisting of 2864 described species belonging to 822 genera at the time of the Neotropical catalog (Guimarães 1971), making it almost twice as species rich as any other geographic realm (O’Hara 2006; Stireman et al. 2006). This diversity is most apparent at middle elevations (1000– 2000m) along the mountain chains of tropical Central and South America, where tachinids are an abundant and …
Autoregulation Of Gld-2 Cytoplasmic Poly(A) Polymerase, Labib Rouhana, Marvin Wickens
Autoregulation Of Gld-2 Cytoplasmic Poly(A) Polymerase, Labib Rouhana, Marvin Wickens
Biological Sciences Faculty Publications
Cytoplasmic polyadenylation regulates mRNA stability and translation and is required for early development and synaptic plasticity. The GLD-2 poly(A) polymerase catalyzes cytoplasmic polyadenylation in the germline of metazoa. Among vertebrates, the enzyme is encoded by two isoforms of mRNA that differ only in the length of their 3′-UTRs. Here we focus on regulation of vertebrateGLD-2 mRNA. We show that the 3′-UTR of GLD-2 mRNA elicits its own polyadenylation and translational activation during frog oocyte maturation. We identify the sequence elements responsible for repression and activation, and demonstrate that CPEB and PUF proteins likely mediate repression in the resting oocyte. …

Caenorhabditis Briggsae Methods, Scott Everet Baird, Helen M. Chamberlin
Biological Sciences Faculty Publications
Caenorhabditis briggsae is being developed in parallel to C. elegans as a model system, primarily for the study of evolution. Like C. elegans, C. briggsae is a protandrous hermaphrodite and like C. elegans, its genome has been sequenced. From this point, these two model systems diverge. The development, behavior, and physiology of C. elegans have been characterized through tens of thousands of genetic and molecular studies. Genetic and molecular characterizations of C. briggsae are relatively few. Experimental resources in C. elegans include a high density recombination map that is well integrated with the genome sequence. The C. briggsae …

Implications Of Spatial Autocorrelation And Dispersal For The Modeling Of Species Distributions, Volker Bahn
Implications Of Spatial Autocorrelation And Dispersal For The Modeling Of Species Distributions, Volker Bahn
Biological Sciences Faculty Publications
Modeling the geographical distributions of wildlife species is important for ecology and conservation biology. Spatial autocorrelation in species distributions poses a problem for distribution modeling because it invalidates the assumption of independence among sample locations. I explored the prevalence and causes of spatial autocorrelation in data from the Breeding Bird Survey, covering the conterminous United States, using Regression Trees, Conditional Autoregressive Regressions (CAR), and the partitioning of variance. I also constructed a simulation model to investigate dispersal as a process contributing to spatial autocorrelation, and attempted to verify the connection between dispersal and spatial autocorrelation in species’ distributions in empirical …

Phylogenetic Reconstruction Of Exoristinae Using Molecular Data: A Bayesian Re-Analysis, John O. Stireman Iii
Phylogenetic Reconstruction Of Exoristinae Using Molecular Data: A Bayesian Re-Analysis, John O. Stireman Iii
Biological Sciences Faculty Publications
A few years ago I published the results of a phylogenetic analysis of New World Exoristinae based on molecular data from two genes, 28S rDNA and Elongation Factor 1-alpha (Stireman 2002). In that study I employed parsimony, neighbor joining, and maximum likelihood inference methods to generate phylogenetic reconstructions, and explored a variety of weighting schemes and combinations of the sequence data (i.e. each gene separately and both together). The results of these analyses generally supported recent taxonomic hypotheses (e.g., Herting 1984; Wood 1987; O’Hara and Wood 2004). For example, Tachinidae and Exoristinae were reconstructed as monophyletic in most analyses, as …
The Genetics Of Ray Pattern Variation In Caenorhabditis Briggsae, Scott Everet Baird, Cynthia R. Davidson, Justin C. Bohrer
The Genetics Of Ray Pattern Variation In Caenorhabditis Briggsae, Scott Everet Baird, Cynthia R. Davidson, Justin C. Bohrer
Biological Sciences Faculty Publications
Background: How does intraspecific variation relate to macroevolutionary change in morphology? This question can be addressed in species in which derived characters are present but not fixed. In rhabditid nematodes, the arrangement of the nine bilateral pairs of peripheral sense organs (rays) in tails of males is often the most highly divergent character between species. The development of ray pattern involves inputs from hometic gene expression patterns, TGFβ signalling, Wnt signalling, and other genetic pathways. In Caenorhabditis briggsae, strain-specific variation in ray pattern has provided an entrée into the evolution of ray pattern. Some strains were fixed for a derived …

Biological Sciences Faculty Publications
Cytoplasmic polyadenylation is important in the control of mRNA stability and translation, and for early animal development and synaptic plasticity. Here, we focus on vertebrate poly(A) polymerases that are members of the recently described GLD2 family. We identify and characterize two closely related GLD2 proteins in Xenopus oocytes, and show that they possess PAP activity in vivo and in vitro and that they bind known polyadenylation factors and mRNAs known to receive poly(A) during development. We propose that at least two distinct polyadenylation complexes exist in Xenopus oocytes, one of which contains GLD2; the other, maskin and Pumilio. GLD2 protein …

Chemical Defenses In Garlic Mustard (Alliaria Petiolata) And Their Potential Role In Species Interactions In Forest Understories, Don Cipollini
Chemical Defenses In Garlic Mustard (Alliaria Petiolata) And Their Potential Role In Species Interactions In Forest Understories, Don Cipollini
Biological Sciences Faculty Publications
Garlic mustard [Alliaria petiolata [(M. Bieb) Cavara & Grande; Brassicaceae] is a European native biennial herb, first recorded on Long Island, NY in the 1860s, and is expanding rapidly in northeastern and midwestern forests in the U.S. and in southern Canada. Garlic mustard flourishes in moist woodlands with moderate exposure to light, but it can grow in a diversity of other habitats. It is found in natural areas, woodlots, and along edges of agricultural fields and lawns throughout North America. Several life history traits likely contribute to the invasiveness of this species. It has a high inbreeding rate and can …
