Extraordinarily precise nematode sex ratios: adaptive responses to vanishingly rare mating opportunitiesJustin Van Goor
Sex ratio theory predicts both mean sex ratio and variance under a range of population structures. Here, we compare two genera of phoretic nematodes (Parasitodiplogaster and Ficophagus spp.) associated with twelve fig-pollinating wasp species in Panama. The host wasps exhibit classic Local Mate Competition: only inseminated females disperse from natal figs, and their offspring form mating pools that consist of scores of the adult offspring contributed by one or a few foundress mothers. In contrast,...
Genome-wide sequence data show no evidence of hybridization and introgression among pollinator wasps associated with a community of Panamanian strangler figsJordan Satler, Allen Herre, Tracy Heath, Carlos Machado, Adalberto Gomez & John Nason
The specificity of pollinator host choice influences opportunities for reproductive isolation in their host plants. Similarly, host plants can influence opportunities for reproductive isolation in their pollinators. For example, in the fig and fig wasp mutualism, offspring of fig pollinator wasps mate inside the inflorescence that the mothers pollinate. Although often host specific, multiple fig pollinator species are sometimes associated with the same fig species, potentially enabling hybridization between wasp species. Here we study the...
Avicennia germinans (L.) L. (Black Mangrove) is a common, sometimes dominant member of intertidal vegetation in tropical and subtropical regions of the Americas and West Africa. Its flowers are known to be attractive to animals – there are records of a variety of floral visitors – and it is widely believed to be zoophilous, but the degree to which it relies on pollinators for full fruit set is not entirely clear. Molecular methods have revealed...
Stereo methods using GOES-17 and Himawari-8 applied to the Hunga Tonga-Hunga Ha’apai volcanic plume on 15 January 2022 show overshooting tops reaching 50-55 km altitude, a record in the satellite era. Plume height is important to understand dispersal and transport in the stratosphere and climate impacts. Stereo methods, using geostationary satellite pairs, offer the ability to accurately capture the evolution of plume top morphology quasi-continuously over long periods. Manual photogrammetry estimates plume height during the...
Data on monitoring the formation of chemical cocktails in urban streams in response to Freshwater Salinization SyndromeSujay Kaushal
Data include the concentration of base cations and nutrients over time and over space in urban streams near the University of Maryland campus in College Park, Maryland, USA. Data were collected longitudinally along streams and over 24-hour time periods. Data on the retention and release of base cations and trace elements were also collected through incubation experiments.
Encoding laboratory testing data: Case studies of the national implementation of HHS requirements and related standards in five laboratoriesRaja Cholan, Gregory Pappas, Greg Rehwoldt, Andrew Sills, Elizabeth Korte, I.

OBJECTIVE: Assess the effectiveness of providing Logical Observation Identifiers Names and Codes (LOINC®)-to-In Vitro Diagnostic (LIVD) coding specification, required by the Department of Health and Human Services for SARS-CoV-2 reporting, in medical center laboratories, and utilize findings to inform future Food and Drug Administration policy on the use of real-world evidence in regulatory decisions. MATERIALS AND METHODS: We compared gaps and similarities between diagnostic test manufacturers’ recommended LOINC® codes and the LOINC® codes used in...
