The COVID-19 pandemic has disrupted life for populations all over the world. One population that has been uniquely impacted by the pandemic is the student-athlete population. Over the last two years, universities took safety precautions by first sending students home and moving teaching and learning to a remote format and...
Postpartum uterine inflammation (endometritis) is not uncommon in beef cattle, resulting in infertility and culling. Prolonged calving may contribute to the increased incidence of endometritis in heifers. Commonly used methods to treat endometritis in beef cattle include intrauterine antibiotics and/or hormone injections, which can result in meat residues. Platelet rich...
Oyster reefs provide an array of ecosystem services. Specifically, they provide structurally complex habitat for fish and invertebrate species such as the commercially important Dungeness crab, Metacarcinus magister. This ecosystem service, once provided by the native oyster Ostrea lurida, is now provided by the commercially cultured oyster Crassostrea gigas in...
The National Ecological Observatory Network (NEON) provides open access data products including sub-daily precipitation amounts and biweekly stable water isotope concentrations at sites across the United States. Stable water isotope (ẟ2H, ẟ18O) concentrations are often used in hydrometeorological studies and models, however the relatively infrequent biweekly sampling intervals of NEON...
Baccalaureate attainment represents an important goal among educators and policymakers.

Global atmospheric carbon levels are continuing to rise from pre-industrial revolution levels. One of the main regulators of global atmospheric carbon levels, and thus climate, is the world's oceans. Unicellular marine cyanobacteria account for a large percent of total marine carbon fixation. We measured chlorophyll-specific ¹⁴C uptake rates (P[superscript b])...

To initiate the defense response to an invading pathogen, plants utilize an array of immune receptors to recognize virulence effectors. Virulence effectors are released by pathogens to suppress immune responses in target hosts. These effectors are recognized by a family of resistance proteins known as nucleotide-binding leucine-rich repeat (NB-LRR) proteins....

Anthopleura elegantissima (Cnidaria: Anthozoa) is an emerging model organism for studying the endosymbiotic relationship between dinoflagellate (genus Symbiodinium) and the cnidarian host. To be developed as a model organism, more genetic resources, like integrated genome and linkage map, are needed. An important validation for developing genomic resources is chromosome number....
