Tonian carbonaceous compressions indicate that Horodyskia is one of the oldest multicellular and coenocytic macro-organisms
(Nature Portfolio, 2023-04)Macrofossils with unambiguous biogenic origin and predating the one-billion-year-old multicellular fossils Bangiomorpha and Proterocladus interpreted as crown-group eukaryotes are quite rare. Horodyskia is one of these few ... -

Climate change and infectious disease: a review of evidence and research trends
(2023-05-16)Background Climate change presents an imminent threat to almost all biological systems across the globe. In recent years there have been a series of studies showing how changes in climate can impact ... -
Soap application alters mosquito-host interactions
(Cell Press, 2023-05)To find nutrients, mosquitoes use volatile organic compounds (VOCs) emitted by plants and animal hosts. These resources overlap in their chemical composition, and an important layer of information resides in VOCs’ relative ... -
Phylogenetic characterization of Orthobunyaviruses isolated from Trinidad shows evidence of natural reassortment
(Springer, 2023-02)The genus Orthobunyavirus is a diverse group of viruses in the family Peribunyaviridae, recently classified into 20 serogroups, and 103 virus species. Although most viruses within these serogroups are phylogenetically ... -
Nitrate limitation in early Neoproterozoic oceans delayed the ecological rise of eukaryotes
(American Association for the Advancement of Science, 2023-03-23)The early Neoproterozoic Era witnessed the initial ecological rise of eukaryotes at ca. 800 Ma. To assess whether nitrate availability played an important role in this evolutionary event, we measured nitrogen isotope ... -
Revealing the complexity of vampire bat rabies “spillover transmission”
(2023-02-13)Background The term virus ‘spillover’ embodies a highly complex phenomenon and is often used to refer to viral transmission from a primary reservoir host to a new, naïve yet susceptible and permissive host ... -
Evaluation of an open forecasting challenge to assess skill of West Nile virus neuroinvasive disease prediction
(2023-01-12)Background West Nile virus (WNV) is the leading cause of mosquito-borne illness in the continental USA. WNV occurrence has high spatiotemporal variation, and current approaches to targeted control of the ... -
Thermal biology of invasive Aedes mosquitoes in the context of climate change
(Elsevier, 2022-06)The increasing incidence of arboviral diseases in tropical endemic areas and their emergence in new temperate countries is one of the most important challenges that Public Health agencies are currently facing. Because ... -
Drugs and Biodiversity Loss: Narcotraffic-Linked Landscape Change in Guatemala
(IntechOpen, 2022-10-13)Characteristic of the Anthropocene, human impacts have resulted in worldwide losses in forested land cover, which can directly and indirectly drive biodiversity loss. The global illicit drug trade is one source of deforestation ... -
Warm Blood Meal Increases Digestion Rate and Milk Protein Production to Maximize Reproductive Output for the Tsetse Fly, Glossina morsitans
(MDPI, 2022-10-31)The ingestion of blood represents a significant burden that immediately increases water, oxidative, and thermal stress, but provides a significant nutrient source to generate resources necessary for the development of ... -
First Evidence of Powassan Virus (Flaviviridae) in Ixodes scapularis in Appalachian Virginia, USA
(American Society of Tropical Medicine and Hygiene, 2022-03-01)Here we report the first detection and confirmation of Powassan virus (POWV) (family: Flaviridae) in Ixodes scapularis ticks collected from Appalachian Virginia. Ixodes scapularis ticks were collected from vegetation across ... -
Bankfull shear velocity predicts embeddedness and silt cover in gravel streambeds
(Wiley, 2022-01)Excess fine sediment (<2 mm) deposition on gravel streambeds can degrade habitat quality for stream biota. Two measures of fine sediment deposition include embeddedness and silt cover (<62.5 mu m). Embeddedness measures ... -

Horsenettle (Solanum carolinense) fruit bacterial communities are not variable across fine spatial scales
(PeerJ, 2021-11-08)Fruit house microbial communities that are unique from the rest of the plant. While symbiotic microbial communities complete important functions for their hosts, the fruit microbiome is often understudied compared to other ... -
A database of common vampire bat reports
(Nature Portfolio, 2022-02-16)The common vampire bat (Desmodus rotundus) is a sanguivorous (i.e., blood-eating) bat species distributed in the Americas from northern Mexico southwards to central Chile and Argentina. Desmodus rotundus is one of only ... -
The Distribution, Seasonal Abundance, and Environmental Factors Contributing to the Presence of the Asian Longhorned Tick (Haemaphysalis longicornis, Acari: Ixodidae) in Central Appalachian Virginia
(Oxford University Press, 2022-05-30)Over the past decade, Haemaphysalis longicornis, the Asian longhorned tick, has undergone a geographic range expansion in the United States, from its historical range in east Asia. This tick has been characterized by its ... -
Pathogen Spillover to an Invasive Tick Species: First Detection of Bourbon Virus in Haemaphysalis longicornis in the United States
(MDPI, 2022-04-10)Haemaphysalis longicornis (Neumann, 1901) (Acari: Ixodidae), the Asian longhorned tick, is an invasive tick species present in the USA since at least 2017 and has been detected in one-third of Virginia counties. ...
