Ralph W Tingley, III, PhD
I am a biologist at the Great Lakes Science Center in Ann Arbor, MI.
I am responsible for the annual assessment of Lake Michigan prey fish populations. I also lead research focused on trophic ecology, recruitment bottlenecks, and habitat use of ecologically and culturally important fishes of the Great Lakes. I am particularly interested in spatial and temporal heterogeneity in fish habitat use within the Great Lakes and connected waters.

A landscape approach for identifying potential reestablishment sites for extirpated stream fishes: an example with Arctic grayling (Thymallus arcticus) in Michigan A landscape approach for identifying potential reestablishment sites for extirpated stream fishes: an example with Arctic grayling (Thymallus arcticus) in Michigan
Habitat degradation combined with climate change increases the threat of extinction for stream fishes. In response to these threats, efforts to reestablish species within formerly occupied streams or translocation to suitable areas may be effective conservation strategies. In the absence of historic species presence data, identifying locations where suitable habitat exists across many...

Status and trends of pelagic and benthic prey fish populations in Lake Michigan, 2021 Status and trends of pelagic and benthic prey fish populations in Lake Michigan, 2021
Lake wide acoustic (AC) and bottom trawl (BT) surveys are conducted annually to generate indices of pelagic and benthic prey fish densities in Lake Michigan. The BT survey has been conducted each fall since 1973 using 12-m trawls at depths ranging from 9 to 110 m and includes 70 fixed locations distributed across seven transects; this survey estimates densities of seven prey fish species...

FiCli, the Fish and Climate Change Database, informs climate adaptation and management for freshwater fishes FiCli, the Fish and Climate Change Database, informs climate adaptation and management for freshwater fishes
Inland fishes provide important ecosystem services to communities worldwide and are especially vulnerable to the impacts of climate change. Fish respond to climate change in diverse and nuanced ways, which creates challenges for practitioners of fish conservation, climate change adaptation, and management. Although climate change is known to affect fish globally, a comprehensive online...

Identifying candidate reference reaches to assess the physical and biological integrity of wadeable streams in different ecoregions and among stream sizes Identifying candidate reference reaches to assess the physical and biological integrity of wadeable streams in different ecoregions and among stream sizes
Efforts to quantify disturbances to aquatic systems often use landscape-level metrics, presumably linked to ecological integrity, but fewer studies have directly linked ecological integrity to instream habitat, and applied these results to unsampled stream reaches throughout a landscape. We developed a flexible, quantitative approach that characterizes stream impairment across a...
