UBAP leader A Rahlin presents Chicagoland ornithological research

UBAP leader Anastasia Rahlin presented two talks recently.

In January Rahlin presented “Oak Masting in the Chicagoland Region” at the Cook County Forest Preserve District – Resource Management talk as part of CCFPD’s Environmental Education program.

Rahlin and collaborators have been collecting oak masting data in the Chicagoland region over a seven-year period from 2017-2023. The talk focused on data regarding northern red, white, and bur oaks and discussed the history of oak masting research, outlined potential hypotheses that explain the likelihood of mast seeding events, and explored preliminary model results linking weather factors such as temperature and precipitation to acorn masts.
This study examines the impact of oak masting on Red-headed Woodpecker populations, an acorn caching species. Preliminary analyses linking acorn masts to Red-headed Woodpecker presence/absence and whether masting influences Red-headed Woodpecker overwintering in northern Illinois sites were also discussed.
In February, Rahlin presented  “Investigating Extreme Weather Impacts on Sedge and Marsh Wren food limitation and nesting success” at the McHenry County Forest Preserve District Research Roundup talk series.
Rahlin has been examining how habitat quality and extreme weather events impact marsh and wet meadow species in northern Illinois. Her talk focused on continued efforts to monitor marsh and sedge wren body condition through wren morphometrics and blood metabolites in order to understand how the two species respond to droughts and storms. Rahlin also discussed nesting outcomes for both wren species, as well as avenues for future research.

New publication from aquatic ecologist Hugo Ruellen

INHS PaCE Lab’s aquatic ecologist, Hugo Ruellen is lead author on a recent publication stemming from his M.Sc. research on freshwater mussels: “Predicting suitable habitat for surrogate species of critically imperiled freshwater mussels to aid in translocations.”

Mussel translocations have been used to mitigate the impacts of in-stream construction projects, including bridge replacements. This work developed a model to predict suitable habitat for mussels. “Knowing where and how much suitable habitat is present in rivers is essential to the conservation and long-term persistence of endangered freshwater mussel species, and habitat suitability models such as these are important tools for achieving these goals.”

Even small urban wetlands can support wetland birds

The landscape surrounding wetlands does not determine use by most wetland birds according to a new study by UBAP Ornithologist Anastasia Rahlin and collaborators Sarah P. Saunders (National Audubon) and Stephanie Beilke (Audubon Great Lakes).

The three researchers have been studying marsh birds in the Chicagoland area for the past 3 years, and their results indicate that even small scale wetland conservation in developed areas can be beneficial to many wetland birds.

Rahlin says, “to me, it’s a hopeful message that yes, restoration does work and is important even in small urban wetlands.”

Five year, $6 million contract awarded to UBAP team

The Urban Biotic Assessment Program was awarded $6,226,400 to continue providing technical assistance to the Illinois Tollway Environmental team.

This is the third intergovernmental agreement between the INHS and the Illinois Tollway and will allow the continuation of this mutually beneficial partnership that began in 2005.

The partnership has grown from monitoring Blanding’s Turtles in the Des Plaines River Valley to a multi-disciplinary program. While the key function is to provide the ecological knowledge necessary to comply with state and federal regulations, both organizations share a goal of studying the natural resources of the region to protect them into the future.

Research projects in this new agreement include biotic surveys of each of the Tollway corridors, continuation of longterm monitoring of the Kishwaukee River mussel population, using eDNA to detect cryptic species, Rusty Patched Bumble Bee surveys, and identifying bat roost trees.
