Tamalia coweni is unusual among gall-forming aphids in that it will often share its gall space with other members of its species, even as this has been shown to lower its fitness. Previous research utilizing manipulated densities of T. coweni on inflo . . .

Meadows in the Sierra Nevada are characterized as wet, heterogeneous habitats with diverse plant communities, often being biodiversity hot spots. These meadows not only provide resources for wildlife but also filter and store snowmelt, providing susta . . .

Zebrafish (Danio rerio) is an excellent model organism for studying embryonic vertebrate development due to their conserved genome with humans, external development, and ease of observation under the microscope. The gene SON is found on the twenty-fir . . .

95% of the cases of chronic myeloid leukemia (CML) are caused by a chromosomal translocation linking the breakpoint cluster region (BCR) gene to the Abelson murine leukemia viral oncogene-1 (ABL1). Downstream of BCR-ABL is growth receptor bound protei . . .

Kelp forest ecosystems are sensitive to changing global environmental conditions and unsustainable fishing practices (Tegner and Dayton 2000). Natural resource managers have implemented marine protected areas (MPAs) to mitigate ecosystem collapse and . . .

Flammulated owls (Psiloscops flammeolus) are small nocturnal owls that are thought to migrate long distances every year from summer breeding grounds in the western United States and southern Canada to winter habitat in Mexico. They are cryptic and elu . . .

This study examined the diets of two predatory fish species, the native Sacramento Pikeminnow (Ptychocheilus grandis) and the introduced Striped Bass (Morone saxitilis), within the Sacramento River, CA, USA. Sampling occurred between March and Decembe . . .

Recent human infections with avian influenza viruses (AIV) highlight the need for continued surveillance of AIV in waterfowl. California’s Sacramento Valley is an important wintering site for waterfowl from which avian influenza viruses may be isolate . . .

My study aimed to quantify nesting habitat availability for cavity-nesting birds in restored and remnant patches of riparian forest on the Sacramento River. I explored three hypotheses: 1) that older restored forests will attract more cavity-nesting b . . .

Walnut (Juglans) and wingnut (Pterocarya) trees have been declining in response to Thousand Cankers Disease (TCD). The TCD pathogen, Geosmithia morbida, is vectored by a phloeophagous bark beetle, the walnut twig beetle (Pityophthorus juglandis Blackm . . .
