Department of Entomology: Faculty Publications
A list of treehoppers (Aetalionidae and Membracidae) is presented from Madre de Dios region at the southeastern Amazon basin in Peru. The treehopper specimens were collected as by-catch in a survey of the beetles in the Villa Carmen Biological Station and Los Amigos Biological Station. The list comprises 44 species, 31 genera, 16 tribes and 9 subfamilies. Ten genera are new records to Peru. The images of representative specimens of each identified species and genera are provided to facilitate the identification of the local treehopper fauna.

Impact Of The Human Footprint On Anthropogenic Mortality Of North American Reptiles, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant
Impact Of The Human Footprint On Anthropogenic Mortality Of North American Reptiles, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant

Human activities frequently result in reptile mortality, but how direct anthropogenic mortality compares to natural morality has not been thoroughly investigated. There has also been a limited examination of how anthropogenic reptile mortality changes as a function of the human footprint. We conducted a synthesis of causespecific North American reptile mortality studies based on telemetry, documenting 550 mortalities of known cause among 2461 monitored individuals in 57 studies. Overall 78% of mortality was the result of direct natural causes, whereas 22% was directly caused by humans. The single largest source of mortality was predation, accounting for 62% of mortality overall. …

The Taxonomic Report of the International Lepidoptera Survey
We obtained and analyzed whole genome shotgun sequences of all 845 species of butterflies recorded from Canada and the United States. Genome-scale phylogenetic trees constructed from the data reveal several nonmonophyletic genera and suggest improved classification of species included in these genera. Here, these changes are formalized and 2 subgenera are described: Amblyteria Grishin, subgen. n. (type species Goniloba exoteria Herrich-Schäffer, 1869, parent genus Amblyscirtes Scudder, 1872), and Coa Grishin, subgen. n. (type species Hesperia baracoa Lucas, 1857, parent genus Polites Scudder, 1872). Furthermore, we resurrect 3 genera and 2 subgenera from synonymy, change the rank of 6 currently used …
The Neotropical Variegated Squirrel, Sciurus Variegatoides (Rodentia: Sciuridae) In Nicaragua, With The Description Of A New Subspecies, Hugh H. Genoways, Robert M. Timm
The Neotropical Variegated Squirrel, Sciurus Variegatoides (Rodentia: Sciuridae) In Nicaragua, With The Description Of A New Subspecies, Hugh H. Genoways, Robert M. Timm
University of Nebraska State Museum: Mammalogy Papers
The Neotropical variegated squirrel, Sciurus variegatoides, is represented in Nicaragua by five known subspecies—adolphei, belti, boothiae, dorsalis, and underwoodi. Analyses of morphometrics, color, and color patterns of 394 specimens from throughout the country and all available literature support the retention of these subspecies, but also reveal the presence of a sixth population of these squirrels, which is worthy of description and recognition as a new subspecies. This new subspecies is confined to Isla de Ometepe in Lago de Nicaragua. Variegated squirrels on Ometepe are on average the smallest variegated squirrels in the country …
Fifty New Genera Of Hesperiidae (Lepidoptera), Qian Cong, Jing Zhang, Jinhui Shen, Nick V. Grishin

Genomic sequencing and analysis of worldwide skipper butterfly (Lepidoptera: Hesperiidae) fauna points to imperfections in their current classification. Some tribes, subtribes and genera as they are circumscribed today are not monophyletic. Rationalizing genomic results from the perspective of phenotypic characters suggests two new tribes, two new subtribes and 50 new genera that are named here: Ceratrichiini Grishin, trib. n., Gretnini Grishin, trib. n., Falgina Grishin, subtr. n., Apaustina Grishin, subtr. n., Flattoides Grishin, gen. n., Aurivittia Grishin, gen. n., Viuria Grishin, gen. n., Clytius Grishin, gen. n., Incisus Grishin, gen. n., …

Commensal rodents (invasive rats, Rattus spp.; house mice, Mus musculus) are well established globally. They threaten human health by disease transfer and impact economies by causing agricultural damage. On island landscapes, they are frequent predators of native species and affect biodiversity. To provide managers with better information regarding methods to suppress commensal rodent populations in remote island forests, in 2016 we evaluated the effectiveness of continuous rat trapping using snap-traps, Goodnature® A24 self-resetting rat traps, and a 1-time (2-application) hand-broadcast of anticoagulant rodenticide bait pellets (Diphacinone-50) applied at 13.8 kg/ha per application in a 5-ha forest on Oahu, Hawaii, USA. …
Necrobiome Framework For Bridging Decomposition Ecology Of Autotrophically And Heterotrophically Derived Organic Matter, M. Eric Benbow, Philip S. Barton, Michael D. Ulyshen, James C. Beasley, Travis L. Devault, Michael S. Strickland, Jeffery K. Tomberlin, Heather R. Jordan, Jennifer L. Pechal

Decomposition contributes to global ecosystem function by contributing to nutrient recycling, energy flow, and limiting biomass accumulation. The decomposer organisms influencing this process form diverse, complex, and highly dynamic communities that often specialize on different plant or animal resources. Despite performing the same net role, there is a need to conceptually synthesize information on the structure and function of decomposer communities across the spectrum of dead plant and animal resources. A lack of synthesis has limited cross-disciplinary learning and research in important areas of ecosystem and community ecology. Here we expound on the “necrobiome” concept and develop a framework describing …
Cause‐Specific Mortality Of The World’S Terrestrial Vertebrates, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant
Cause‐Specific Mortality Of The World’S Terrestrial Vertebrates, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant

Aim: Vertebrates are declining worldwide, yet a comprehensive examination of the sources of mortality is lacking. We conducted a global synthesis of terrestrial vertebrate cause‐specific mortality to compare the sources of mortality across taxa and determine predictors of susceptibility to these sources of mortality.
Location: Worldwide.
Time period: 1970–2018.
Major taxa studied: Mammals, birds, reptiles and amphibians.
Methods: We searched for studies that used telemetry to determine the cause of death of terrestrial vertebrates. We determined whether each mortality was caused by anthropogenic or natural sources and further classified mortalities within these two categories (e.g. harvest, vehicle collision and predation). …
