Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...
Koi herpesvirus (KHV) is highly pathogenic to Cyprinus carpio. KHV can also become latent in recovered fish and reactivate from latency under stressful conditions. Understanding KHV latency is important for development of strategies against herpesvirus latent infection. Our previous studies found KHV ORF6 mRNA is detectable during latent infection. In...
Models that seek to predict environmental variables invariably demonstrate bias when compared to observations. Bias correction (BC) techniques are common in the climate and hydrological modeling communities, but have seen fewer applications to the field of wave modeling. In particular there has been no investigation as to which BC methodology...
Rebuilding of some U.S. West Coast rockfish (Sebastes spp.) stocks relies heavily on mandatory fishery discard, however the long-term condition of discarded fish experiencing capture-related barotrauma is unknown. We conducted two studies designed to evaluate delayed mortality, physical condition,and behavioral competency of yelloweye rockfish, Sebastes ruberrimus, experiencing barotrauma during capture...

whale Eubalaena australis population in New Zealand by
whaling, research on its recovery has focused on the wintering
ground at the Auckland Islands, neglecting potentially
important wintering habitat at Campbell Island. For
the first time in 20 years we conducted an expedition to...
Periodic weighing of seabird chicks is labour-intensive and repeated handling can cause high levels of disturbance to chicks. Although automatic weighing systems using a fibreglass nest have been designed for albatross species with a pedestal nest made of mud, this approach is inappropriate for great albatross species (genus Diomedea) whose...
Streams that dry during part of the year are common throughout the world, yet studies of the macroinvertebrate assemblages in these types of streams are rare compared to those in permanent streams; and studies that assess the effects of agriculture on temporary stream invertebrates are even rarer. We studied macroinvertebrate...
The DUNE near detector will be used to characterize the LBNF neutrino beam and to predict the neutrino fluxes at the DUNE far detector. Because of the different detector locations with respect to the beam-line, energy spectra at the two detectors will be slightly different, even in the absence of...

Fact/value holism has become commonplace in philosophy of science, especially in feminist literature. However, that facts are bearers of empirical content, while values are not, remains a firmly-held distinction. I support a more thorough-going holism: both facts and values can function as empirical claims, related in a seamless, semantic web....
