Erin Conlisk, Postdoctoral Research Fellow


My PhD dissertation, surpervised by Professor John Harte at UC
Berkeley, developed quantitative methods for analyzing the spatial
distribution of species, and applied the results to censuses of
tropical forests and a serpentine grassland. The methods are relevant
to spatial autocorrelation, the study of community biodiversity, the
fate of rare species, the species area relationship, and the
prediction of abundance at multiple spatial scales.

In Helen Regan’s lab at UC Riverside, I am studying models which link
population dynamics to climate niche models.  We are applying the
hybrid models to California plants, estimating extinction risks due to
climate change, altered fire regimes, and urban growth.  Complementing
this work, I am exploring climate niche model sensitivity to
uncertainty in input data.

Rebecca Swab, PhD student

I received a B.S. degree with honors in Environmental Science (specializing in Wetland Science)and a Master of Science degree in Natural Resources (specializing in Ecosystem Science), both from Ohio State University.

For my Ph.D. thesis, I am performing population level modeling analyses for plant congeners in the Californian chaparral, Chilean mattorral, and the Australian heathland. Comparing species from these similar systems will bring to light general patterns in the responses of mediterranean plants to synergistic processes such as climate change and changing fire regimes.  These modeling methods can then be used to predict areas and species with high extinction risk.  Decision makers could implement this information to ensure continuation of ecosystem function in the presence of climate change and anthropogenic influences.


Pamela Rueda-Cediel, PhD Student

I received a Bachelors degree in Biology from the Universidad Industrial de Santander in Bucaramanga, Colombia. I have assisted with a range of field- and lab-based projects including:

  • the ovarian and oviductal morphology of a brood parasitic bird in Columbia,
  • reproductive cycle of Creagrutus guanes in a tropical mountain river
  • the breeding biology of Steller´s eiders in Barrow, Alaska, with the Fairbanks Fish and Wildlife field office
  • variation of the abiotic component and the vertical distribution of  Cladocera and Copepoda during the rainy and dry seasons in an Andean lake  
  • reproductive biology of the fish Geophagus stendachnerii in the Fonce River, Santander, Columbia
  • water bird monitoring program in the south pacific region of Columbia

I am currently investigating the ability of population models to accurately estimate rates of decline across species from a range of taxonomic groups. I am using publicly available time series population data to address the following questions:

    1. How do population decline estimates differ between scalar and matrix models across a range of taxonomic groups?

    2. How many years of data is required to attain robust risk estimates for species from different taxonomic groups?

    3. Does this depend on whether scalar or matrix models are used to estimate declines?
