Marchetti Lab Graduate Student Research Projects:

Current Graduate Students





    

Heather Bowen - Habitat induced phenotypic variation in juvenile salmon using Geometric Morphometrics.   Heather is using a statistical technique to look at physical variation in juvenile salmonid body shape from fish that are reared in permanent waterbodies (i.e. the Sacramento River) as compared to seasonal water bodies (i.e. Mud Creek)

becky and sturgeon

Becky Walther - Spatial distribution of native fish larvae.  Becky is examining spatial patterns of larval fish distribution and abundance in seasonal stream habitat (Mud Creek).  


aquatic insect sampling

Gina Benigno - Aquatic Macroinvertebrate use of seasonal tributaries.  Using a combination of field collection techniques, Gina will be examining the use and colonization of a seasonal tributary (Mud Creek) by aquatic macroinvertebrates over a year-long period.  

 

Past Graduate Students

mike limm
 
 Mike Limm. MS 2003- Juvenile Chinook salmon use of off-channel flooded vegetation: Working with the Nature Conservancy,  Mike (UC Berkeley) asked the question of wether off-channel habitats (seasonal backwaters and temporary stream habitat) is good for the rearing of juvenile salmonids who use the shallow water during floods. He did this using otolith microstructure analysis of fall run chinook salmon. 
Mike is currently finishing up his PhD at UC Berkeley in the Power lab.

elaine esteban
  

Elaine Esteban MS 2002 - Effect of flow variation on the macroinvertebrate ecology and salmonid feeding in the Feather River: Elaine, investigated the influence of the Oroville Dam complex on  the feeding preferences of juvenile salmonids.  She tested a food availability model using juvenile steelhead trout and chinook salmon.   She and I are currently writing a second manuscript from her masters research using community ordination techniques to examine the macroinvertebrate fauna in two highly flow regulated sections of the Feather River.
Elaine is currently fully employed as a mother of two young children living in Vancouver BC.

 ryon kurth
  
Ryon Kurth - MS 2006 Tracing marine-derived energy pathways in the Feather River.- Ryon examined the structure of the aquatic food web in the lower Feather River using stable isotopes.  He investigated the effect severe flow manipulation has on the aquatic organisms in the river.
Currently Ryon is employed as a Field Director by the California Department of Water Resources in Oroville CA
mariah garr
  
Mariah Garr - MS 2007 Wetland Restoration and its effects on the macroinvertebrate community .  Mariah investigated temporal changes in the aquatic macroinvertebrate assemblages associated with vegetative restoration of wetlands in the Central Valley.  Specifically examined whether there are predictable faunal assemblages associated with restored wetlands over a 50 year chronosequence of wetland restoration.
Mariah currently is employed by the CSU Chico Research Foundation and a laboratory assistant

elastomer marked R. boyleii Kyle Hartwigsen - MS 2007. Interactions between California native yellow-legged frogs (Rana boyleii) and introduced bullfrogs (R. catesbeiana):  Kyle investigated the effect bullfrogs have on the habitat and abundance of yellow-legged frogs in Dye Creek, a Nature Concervancy reserve in Northern California.
Kyle is currently employed as a scientific aid by the Department of Water Resources in Oroville CA.
Alicia Seesholtz - MS 2008 - Catch Selectivity of Fish Larvae using different gear type and placement. - Alicia's work examined the ability to collect fish larvae in a large river using multiple gear types and alternative gear placement in the river.  She did her reserch on the Lower Feather River CA.
Alicia is currently employed by the California Department of Water Resources.
