Genome-Wide Variation In Potyviruses, Deepti Nigam, Katherine Latourrette, Pedro F.N. Souza, Hernan Garcia Ruiz
Genome-Wide Variation In Potyviruses, Deepti Nigam, Katherine Latourrette, Pedro F.N. Souza, Hernan Garcia Ruiz

Potyviruses (family Potyviridae, genus Potyvirus) are the result of an initial radiation event that occurred 6,600 years ago. The genus currently consists of 167 species that infect monocots or dicots, including domesticated and wild plants. Potyviruses are transmitted in a non-persistent way by more than 200 species of aphids. As indicated by their wide host range, worldwide distribution, and diversity of their vectors, potyviruses have an outstanding capacity to adapt to new hosts and environments. However, factors that confer adaptability are poorly understood. Viral RNA-dependent RNA polymerases introduce nucleotide substitutions that generate genetic diversity. We hypothesized that selection imposed by …

This data article provides the methods and procedures followed to collect and analyse soil, vegetation and bird data on three different treatment islands in Guntersville Reservoir, Alabama. Samples were collected from randomly selected plot points from islands that were placed into three different treatment types: Colony (currently occupied by Double-crested Cormorants) (Phalacrocorax auritus; n 1⁄4 5), Historic (historically occupied by cormorants and currently abandoned; n 1⁄4 3) and Reference (never occupied by cormorants; n 1⁄4 4). We compared vegetation and tree metrics such as structure and diversity, as well as soil chemistry and bird diversity and communities among islands within …

Effects of Double-crested Cormorants (Phalacrocorax auritus) on vegetation, soil chemistry and tree health have been documented from their breeding colonies in the northern breeding grounds of Canada and the United States (U.S.) but not for areas within the southeastern United States where breeding activity is relatively novel. We compared vegetation and tree metrics such as structure diversity, and soil chemistry among colony islands, uninhabited islands, and abandoned colony islands within Guntersville Reservoir, a temperate forest ecosystem. Avian diversity and community structure were also quantified on these islands. Concentrations of potassium (K), phosphorus (P) and nitrate (NO3 −) in soil were …

Spatial And Temporal Distribution Of The Forensically Significant Blow Flies Of Los Angeles County, California, United States (Diptera: Calliphoridae), Royce T. Cumming
School of Natural Resources: Dissertations, Theses, and Student Research
Forensic entomology although not a commonly used discipline in the forensic sciences, does have its niche and when used by investigators is respected in crinimolegal investigations (Greenberg and Kunich, 2005). With many species of forensically significant insects being regionally specific, it is often difficult for forensic entomologists to as confidently translate regionally specific studies across drastically differing geographic regions (Brundage, et al., 2011).
The purpose of this study is to help create a better temporal and geographic distributional understanding of the blow fly species present in Los Angeles County, California, United States. Twenty-five locations from four ecoregions (coastal mountains, urban, …
Composition And Host-Use Patterns Of A Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting The Canopy Of A Lowland Tropical Rainforest In Southern Venezuela, Susan Kirmse, Brett C. Ratcliffe
Composition And Host-Use Patterns Of A Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting The Canopy Of A Lowland Tropical Rainforest In Southern Venezuela, Susan Kirmse, Brett C. Ratcliffe

The adult scarab beetle fauna of the canopy in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a 42 m-tall tower crane for a complete year. This first census of an entire Amazonian canopy scarab community was embedded within the interdisciplinary research project "Towards an understanding of the structure and function of a Neotropical rainforest ecosystem with special reference to its canopy" organized by the Austrian Academy of Science. The Scarabaeidae represented one of the most species-rich beetle families in the canopy of the crane plot and were therefore selected for a detailed analysis …
