Raspberries are an important commodity worldwide, with the United States (U.S.) leading fourth in global production in 2017. An important factor when shipping propagated Rubus across the globe is the security of clean plant material verified through pathogen detection methods which is vital in preventing disease spread. A raspberry virus...
The Bering Sea is a highly productive ecosystem with abundant prey populations in the summer that support some of the largest seabird colonies in the Northern Hemisphere. In the fall, the Bering Sea is used by large numbers of migrants and post-breeding seabirds. We used over 22000 km of vessel-based...

Metagenomics has revealed that the marine microbial biosphere is immensely more diverse than originally considered, and is an almost untapped reservoir for the potential discovery of microbial natural products. Despite numerous advances in culturing, biosynthetic engineering and genomic-based screening efforts to uncover much of this diversity in relatively accessible environments,...
Landscape fire succession models (LFSMs) predict spatially–explicit interactions between vegetation
succession and disturbance, but these models have yet to fully integrate ungulate herbivory as a driver of
their processes. We modified a complex LFSM, FireBGCv2, to include a multi-species herbivory module,
GrazeBGC. The system is novel in that it explicitly...
The Aleutian tern (Onychoprion aleuticus) is a species of high conservation concern in Alaska due to large declines at known breeding locations since the 1960s. Due to the small population size and ephemeral behavior of this species on the nesting grounds, there is little basic biological information available and data...
Numerous studies have examined the evolution of sexual systems in angiosperms, but few explore the
interaction between these and the evolution of pollination mode. Wind pollination is often associated
with unisexual flowers, but which evolved first and played a causative role in the evolution of the other
is unclear. Thalictrum,...
An improved extraction and HPLC method for the simultaneous extraction and quantitation of retinol, α-tocopherol, α-tocotrienol and β-carotene was developed to analyze commercial whole/semi-skim/skim samples of raw/pasteurized/UHT milk in transparent plastic/glass bottles and Tetra Brik™ containers. The sample preparation method required prior saponification at 40ºC for 15 min followed by...
