Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -
Insect Orders V: Panorpida & Hymenoptera
Insect Orders V: Panorpida & Hymenoptera • The Panorpida contain 5 orders: the Mecoptera, Siphonaptera, Diptera, Trichoptera and Lepidoptera. • Available evidence clearly indicates that the Lepidoptera and the Trichoptera are sister groups. • The Siphonaptera and Mecoptera are also closely related but it is not clear whether the Siponaptera is the sister group of all of the Mecoptera or a group (Boreidae) within the Mecoptera. If the latter is true, then the Mecoptera is paraphyletic as currently defined. • The Diptera is the sister group of the Siphonaptera + Mecoptera and together make up the Mecopteroids. • The Hymenoptera does not appear to be closely related to any of the other holometabolous orders. Mecoptera (Scorpionflies, hangingflies) • Classification. 600 species worldwide, arranged into 9 families (5 in the US). A very old group, many fossils from the Permian (260 mya) onward. • Structure. Most distinctive feature is the elongated clypeus and labrum that together form a rostrum. The order gets its common name from the gential segment of the male in the family Panorpodiae, which is bulbous and often curved forward above the abdomen, like the sting of a scorpion. Larvae are caterpillar-like or grub- like. • Natural history. Scorpionflies are most common in cool, moist habitats. They get the name “hangingflies” from their habit of hanging upside down on vegetation. Larvae and adult males are mostly predators or scavengers. Adult females are usually scavengers. Larvae and adults in some groups may feed on vegetation. Larvae of most species are terrestrial and caterpillar-like in body form. Larvae of some species are aquatic. In the family Bittacidae males attract females for mating by releasing a sex pheromone and then presenting the female with a nuptial gift. -

Betts Revised: 29 July 20 II/Accepted: 9 August 20II ��. Springer Seicnee+Business Media, LLC 2011 Abstract Discerning the intricacies of mating systems in butterflies can be difficult, particularly when multiple mating strategies are employed and are cryptic and not exclusive. We observed the behavior and habitat use of 113 male Taylor's checkerspot butterflies (Euphydryas editha taylori). We confinned that two distinct mating strategies were exhibited; patrolling and perching. These strategies varied temporally in relation to the protandrous mating system employed. Among perching males, we recorded high site fidelity and aggressive defense of small «5 m2) territories. This telTitoriality was not clearly a function of classic or non-classic resource defense (i.e., host plants or landscape), but rather appeared to constitute guarding of female pupae (virgin females). This discrete behavior is previously undocumented for this species and has rarely been observed in butterflies.

Competition between males for sexually receptive females has led to the evolution of a large variety of mating systems in this taxon (Rutowski 1991). Among these mating systems, mate acquisition strategies, such as mate locating, V J. Bennett (18) . M. G. Betts Department of Forest Ecosystems and Society, Oregon State University. -
ABSTRACT Hill, Hilary Nan. Phylogenetic Utility of Two New Nuclear Genes, Opsin and CAD, Within the Stiletto Flies (Diptera: Th
ABSTRACT Hill, Hilary Nan. Phylogenetic Utility of Two New Nuclear Genes, Opsin and CAD, within the stiletto flies (Diptera: Therevidae) (Under the direction of Brian M. Wiegmann). A need for multiple phylogenetic markers to reconstruct evolutionary relationships is increasingly apparent within both the Therevidae and insect systematics as a whole, especially markers that can accommodate the immense species diversity that arose during the Mesozoic (~65-250mya). Phylogenetic trees are often best reconstructed using datasets from distinct sources and from character sets that have been under different selective pressures. Many recent insect systematics studies use various combinations of markers from multiple genomes, morphology, and biogeography. Nuclear genes, particularly protein-encoding genes that are highly conserved and low copy-number, are increasingly attractive as phylogenetic markers, and there is a recent concerted effort to find and increase access to new nuclear genes. Chapter one of this study investigates the phylogenetic utility of opsin, a new multiple copy nuclear protein- encoding gene in the dipteran family Therevidae. The present analyses of nucleotide sequence data of opsin reconstructed a therevid phylogeny that is partially concordant with previous classifications which demonstrates that opsin may have some limited utility as a phylogenetic marker within the Therevidae and closely related Diptera, but also shows that opsin may be better used in combination with other molecular markers or morphological data sets. Phylogenetic analyses of opsin at multiple levels within insects supports these results, but also reveals the significant obstacles in technical manipulation of the gene and in the interpretaion of ortholog/paralog relationships. In the second chapter two new nuclear, protein-encoding genes, opsin and CAD, in combination with EF-1α and 28S rDNA, are applied to reconstruct evolutionary relationships among the major lineages of Therevidae for which previous molecular evidence has been insufficient. -

We describe a rearing protocol that allowed us to raise the threatened butterfly, Argynnis diana (Nymphalidae), while bypassing the first instar overwintering diapause. We compared the survival of offspring reared under this protocol from field-collected A. diana females from North Carolina, Georgia, and Tennessee. Larvae were reared in the lab on three phylogenetically distinct species of Southern Appalachian violets (Viola sororia, V. pubescens,andV. pedata). We assessed larval survival in A. diana to the last instar, pupation, and adulthood. Males reared in captivity emerged significantly earlier than females. An ANOVA revealed no evidence of host plant preference by A. diana toward three native violet species. We suggest that restoration of A. diana habitat which promotes a wide array of larval and adult host plants, is urgently needed to conserve this imperiled species into the future. 1.

Frequency of Pathology in a Large Natural Sample from Natural Trap

Rothschild1, L.D. Martin2 1The Arthritis Center of Northeast Ohio, University of Kansas Museum of Natural History, Carnegie Museum of Natural History, Northeastern Ohio Universities College of Medicine and University of Akron; 2Museum of Natural History and Department of Systematics and Ecology, University of Kansas, Lawrence, Kansas 66045 RIASSUNTO Nel presente studio vengono riportati i rilievi paleopatologici, con particolare riguardo alla presenza di artrite ero- siva, di osteoartrosi, di DISH , nonché ai segni di danno della dentizione, relativi ad un’ampia popolazione di mam- miferi, i cui resti (più di 30.000 ossa di 24 specie diverse) sono stati ritrovati nella Natural Trap Cave, Wyoming, USA. L’evidenza di artrite erosiva è confinata ai bovidi, Bison, Ovis e Bootherium, fatto osservabile anche in bisonti del tardo Pleistocene ritrovati nel Kansas (Twelve Mile Creek) e in un’altra località del Wisconsin, riferibile cronologi- camente al primo Olocene. Questi dati, ovvero la restrizione di tali segni di patologia articolare ad un singolo gene- re animale (Bovidi) e ad un determinato periodo storico, rende plausibile l’ipotesi che un agente patogeno, identifi- cabile col Mycobacterium tubercolosis, possa essere stato implicato nella genesi dell’artrite erosiva. Osteoartrosi e DISH sono risultate poco rappresentate nella popolazione animale della Natural Trap Cave, anche se il genere Bi- son ha dimostrato una discreta prevalenza di segni di osteoartrosi.
