I am the alpha nerd. My interests span a wide variety of topics at the intersection of theoretical, empirical, and applied ecology, and I have explored these interests in both aquatic and terrestrial systems. I am particularly interested in how populations and communities respond to environmental variation, both natural and human driven, and I use a mixture of mathematical and empirical approaches to understand processes that act across scales of spatio-temporal measurement and biological organization.

My work spans the ecology and conservation of large carnivores with a focus on cheetahs. I am also interested in using social media as a tool for science communication and am currently working on ways to bring ecology classes into the digital realm. Learn more at annehilborn.moonfruit.com

I am most interested in food webs and community ecology of stream systems in the context of flow disturbance (i.e. floods and droughts). My primary study sites are at the Sierra Nevada Aquatic Research Laboratory (SNARL, a UC Natural Reserve), and the Santa Ana River.

The goal of my current research is to understand how dispersal links local food web dynamics through the framework of community assembly. My approach is focusing on how whole food webs assemble in a spatial ecological context. I am currently doing this in modeling simulations and in laboratory microcosm studies using protozoa as a model system. Starting with a population to community approach, I am measuring species specific dispersal and growth rates in order to understand how protist species differ in their dispersal ability and population dynamics. This work on population dynamics gives us the background knowledge of these species necessary to understand how they assemble from complex regional food webs. Another side project I’m developing is centered around local community structure of alpine lakes in the Eastern Sierra Nevada’s as a function of spatial connectivity. More to come on this soon!

I received my B.S. in Environmental Science in 2016 where I studied the invasion of Orconectes rusticus (rusty crayfish) in Southeastern Pennsylvania.
I am interested in the spatial and abiotic processes that shape aquatic macroinvertebrate communities in dendritic systems. My first year project is focused on analyzing large spatio-temporal scale datasets using geographic information systems to examine how anthropogenic damming of streams alters community composition of aquatic arthropods. I am also interested in how character traits including dispersal ability allow species to persist in changing habitats.
I am interested in spatio-temporal interaction of stochastic populations.
The "Bleph Buddies" have been working in the lab as participants in UCR's Summer RISE program, funded by an NSF CAREER Award. Helen Chen, Christina Dang, Shubh Dhruv, Richard Martinez, Dulce Rios, and Megan Whitesell conducted independent projects using protist microcosms.
Cyrus has been working with Matthew Green this field season in the Sierra Nevada and participated in UCR's MSRIP program. His independent project has been to analyze spatial patterns of benthic and pelagic chlorophyll in lake/stream chains.
Rosa joined us as part of UCR's Summer Bridge to Research Program. This summer she worked on quantifying bacterial dynamics in protist microcosms using a mix of direct counts and image analysis techniques.
