Jeffrey is a MSc student in Watershed Sciences and Ecology. Originally from El Sobrante, California, he received a B.S. in Environmental Science & Management from University of California, Davis. At USU, Jeffrey's current research focuses on mapping potential shifts in climate regime and landscape connectivity across Utah's ecoregions and modeling the prioritization of conservation efforts in light of projected regional change. His broad interests in conservation ecology are based in studying how best to conserve and reconcile biologically-diverse ecosystems in landscapes that have experienced or are undergoing high levels of anthropogenic change, with particular focuses on urbanization and climate change. When he's not busy studying ecology, Jeffrey enjoys playing music, hiking, boating, and generally anything else that gets him outdoors.
Josh is a MSc student in Watershed Sciences and Ecology, and is from Grand Rapids, Michigan. He is proud to be part of the multi-disciplinary research team on the Diamond Fork restoration project. The aim of the project is to understand the effects of reduced flow on fluvial processes and aquatic ecosystem functioning in Diamond Fork River / Sixth Water Creek, a system which historically has had artificially high flows. In particular, Josh is studying how macroinvertebrate populations in Diamond Fork / Sixth Water respond to different flow regimes. His research interests are aquatic ecosystem productivity and anthropogenic stressors on river systems. Josh is co-supervised by Trisha Atwood at USU.

Charlie completed his honours thesis in 2015 under the supervision of Dr Edd Hammill at the University of Technology, Sydney. His research focused on the impact of invasive species on freshwater ecosystems at the community and ecosystem level, with specific regards to Mosquitofish (Gambusia holbrooki) in lentic ecosystems of New South Wales, Australia. Through this work he received a UTS University Medal for achieving the highest grade in his cohort. Charlie currently works in ecological restoration, specialising in wetlands, riparian zones and saltmarshes, and plans to continue his research career through a PhD in 2017.

Dr. Edd Hammill co-supervised me in the latter stages of my PhD (2015-2016) at the University of Technology, Sydney in Australia. My research investigated the importance of the identity of adjacent habitats in determining edge effects for a cross section of seagrass (Posidonia australis) fauna i.e. fish, zooplankton, benthic invertebrates and epiphytes (measured as epiphyte load) on the New South Wales coast. The research incorporated a manipulative aquarium experiment investigating the habitat combination and heterogeneity level preferences of select seagrass fish in the presence and absence of predatory threat. I am currently back in my home country (Jamaica) and am a full-time lecturer of Environmental Studies at the University of Technology, Jamaica in the Faculty of Science and Sport, Environmental Sciences Division.

Quinn's research interests are in environmental management and policy, biogeochemical cycling, trophic cascades effects on community structure, and ecosystem functions of coastal vegetated or 'blue carbon' ecosystems. Quinn completed his first research project under Dr Edd Hammill's supervision, investigating changes in community structure and distribution of benthic invertebrates due to habitat edge effects across posidonia australis seagrass beds. He then continued to complete an Honours year with Dr Hammill producing a first class thesis looking at how predator induced trophic cascades alter benthic communities and sedimentary carbon stocks in the Great Barrier Reef. Quinn is currently completing a PhD at Deakin University, Melbourne, Australia, researching the function of seagrasses, tidal marshes and mangroves as highly productive atmospheric carbon sinks, with the aim to aid in future environmental policy decisions and management across Australia.

Coreen spent an undergraduate directed studies course exploring the consumptive and non-consumptive effects of predators in the Srivastava Lab supervised by Edd during his Post Doctoral appointment at UBC. Conducting experiments in protist microcosms allowed the study of many generations of a multi-trophic community in only a semester. This work was published in Oikos as an editor's choice article.
Currently, Coreen is working towards a PhD in the O'Connor Lab at UBC. She studies metacommunity processes in eelgrass food webs and how climate change may affect these processes over multiple spatial scales.
