The Oriental hornet, Vespa orientalis Linnaeus, 1771 (Hymenoptera, Vespidae): diagnosis, potential distribution, and geometric morphometrics across its natural distribution range

Autor: Allan H. Smith-Pardo, Mariano Altamiranda-Saavedra, P. David Polly

Publikováno v: Frontiers in Insect Science, Vol 4 (2024)

We present a short review of the biology, diagnostic characteristics, and invasiveness of the Oriental hornet, Vespa orientalis. We also performed an analysis of the shape of the forewings (geometric morphometrics) of different geographic groups alon

Identifying Morphs of the Yellow-Legged Hornet (Vespa velutina) and Other Pests of Quarantine Importance with Geometric Morphometrics

Autor: Allan Smith-Pardo, P. David Polly, Todd Gilligan

Publikováno v: Diversity, Vol 16, Iss 7, p 367 (2024)

We assess the accuracy of geometric morphometrics (GMM) for determining the origin of insects of quarantine importance using the Asian hornet (Vespa velutina Lep.1836) as a case study. This species is highly variable, has an extensive natural distrib

Shrews, Chromosomes and Speciation

Autor: Jeremy B. Searle, P. David Polly, Jan Zima

The chromosome complement (karyotype) often differs between related mammalian species (including humans vs chimpanzees), such that evolutionary biologists muse whether chromosomal difference is a cause or a consequence of speciation. The common shrew

Novel 2D long film imaging utility to avoid wrong level spinal surgery

Autor: Rajiv Dharnipragada, BA, Bryan Ladd, MD, Kristen Jones, MD, David Polly, Jr., MD

Publikováno v: Radiology Case Reports, Vol 17, Iss 7, Pp 2400-2403 (2022)

Wrong-level spinal surgery (WLSS) can lead to increased morbidity, cost, and worse long-term outcomes. Current intraoperative localization methods rely on counting spinal levels from a known reference location using fluoroscopy. Miscounting from a re

Extinction and morphospace occupation: A critical review

Autor: P. David Polly

Publikováno v: Cambridge Prisms: Extinction, Vol 1 (2023)

Processes of extinction, especially selectivity, can be studied using the distribution of species in morphospace. Random extinction reduces the number of species but has little effect on the range of morphologies or ecological roles in a fauna or flo

Incidental extraspinal imaging findings on adult EOS full body radiographs: prevalence and clinical importance

Autor: Lily Wood, Christopher Martin, David Polly, Samuel Luchsinger, Takashi Takahashi

Publikováno v: BMC Medical Imaging, Vol 21, Iss 1, Pp 1-11 (2021)

Abstract Purpose The purpose of this study was to review our institutional experience with the EOS machine in order to identify the incidence and clinical significance of incidental extraspinal findings (IESF) in an adult spinal deformity population.
