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.

PACE Lab researchers awarded two Competitive State Wildlife Grants

Two projects from the INHS PACE Lab were among the 21 projects funded nationally by the 2021 U.S. Fish and Wildlife Service’s Competitive State Wildlife Grant (C-SWG) program.

The first cooperative project is with the Iowa and Illinois Department of Natural Resources, allocated at $499,797 for the joint project titled “Blanding’s Turtle Conservation in Iowa and Illinois, 2022 through 2024”.  The project team from the Illinois Natural History Survey (INHS) and National Great Rivers Research and Education Center (NGREEC) comprises Ethan J. Kessler, Michael J.  Dreslik, Andrew R. Kuhns, and John A. Crawford. The team was awarded $249,449 for their portion of the project, “Population Assessment and Space Use in a Kankakee Sands Region Blanding’s Turtle Population.” While much work has been done on Blanding’s Turtle populations in the Chicagoland region, this project focuses on lesser-known populations in the Kankakee Sands Conservation Opportunity Area.

The grant will facilitate an intensive capture-mark-recapture study to determine population size and begin to collect demographic data. A subset of turtles will be tracked using radio telemetry and GPS trackers to monitor survival and determine space and habitat use. The data is necessary to determine the amount and extent of suitable habitat available on the landscape and address causes of mortality for this population. The work will build on previous research on Blanding’s Turtles in Illinois and further inform conservation planning.

musselsThe second cooperative project is with the Minnesota Department of Natural Resources allocated at $247,892 for the joint project titled, “Regional Assessment of Widespread Mussel Declines: a Multistep Approach to Examine Potential Causes.” The project team from the INHS comprises Sarah A. Douglass and Alison P. Stodola while INHS alum Bernard Sietman will lead Minnesota’s portion. The INHS team was awarded $113,364 for their portion of the project. Freshwater mussels, an ecologically important component of river ecosystems, are experiencing widespread declines. With the award, Douglass and Stodola will investigate potential causes for these declines with the goal of informing conservation guidelines and recovery planning. Additionally, this study is an expansion of a largescale, cooperative project spearheaded by Dr. Wendell Haag, US Forest Service Research Fisheries Biologist, and American Rivers to examine causes of freshwater mussel declines across North America.

Researchers will assess pairs of rivers with similar historic mussel assemblages, comparing a river with relatively intact mussel assemblages and a river with a degraded assemblage. They will develop health metrics and assess habitat characteristics to identify potential causal factors of decline. Juvenile mussels will be propagated and used to assess health in response to potential causes of decline. Another part of the project will use eDNA and targeted sampling to update knowledge of Salamander Mussel populations in Illinois and Minnesota. The research will build on a pilot project previously undertaken by Douglass to use eDNA to detect the critically imperiled species and its host, the Mudpuppy salamander.

In granting these awards, USFWS recognizes the necessity of these two projects to further the goals of the Illinois Wildlife Action Plan to conserve imperiled species and their habitats.

 

Radio telemetry used to improve environmental DNA use

Alligator Snapping Turtle

Environmental DNA (eDNA) is an emerging tool used to detect rare and difficult to detect species. A recent study by INHS PACE Lab herpetologists used radio telemetry to evaluate and improve the efficiency of this technique.

As part of a species reintroduction program, hatchling Alligator Snapping Turtles reared in captivity were tracked using radio telemetry to assess their survival. This work provided an ideal system for evaluating the efficacy and limitations of using eDNA to detect a bottom dwelling riverine turtle. At each radio location, water samples were collected as well as upstream and downstream of the turtle.

The researchers found that eDNA can be used to detect a benthic turtle species but that detection can be diminished by UV exposure from open canopy. This study shows the importance of continuing to use traditional methods such as radio telemetry to better understand the dynamics of eDNA in the environment.

PaCE Lab at the Illinois State Fair

Members of the PaCE Lab exhibited in Conservation World at the 2019 Illinois State Fair, providing information and education to over 500 visitors. In addition to displays about the research being done by the group, visitors were able to try their hand at using actual field equipment used by scientists in their daily work.

The Illinois Bat Conservation Program had a mist net deployed where visitors could untangle, identify, and measure bats, all while wearing leather gloves.

The Amphibian and Reptile Conservation group had snake tongs, hooks, calipers, and radio telemetry equipment available for visitors to try to wrangle snakes into a snake bag, measure turtles, or track a hidden turtle.

Other activities included Build-a-Bug, where people can assemble the arthropod of their dreams (or nightmares) from a variety of general and specialized appendages, Wheel of Migration, about the risks migratory birds face, and locating PIT-tagged animals.

UBAP Ornithologist Rahlin receives Kushlan Research Award

Black-crowned Night Heron
Black-crowned Night Heron

UBAP Ornithologist Anastasia Rahlin received the Kushlan Research Award  from the Waterbird Society to assist her research project entitled “Using environmental DNA sampling to determine heron and bittern occupancy in western and northern Michigan: a metagenomics approach.”

This work will improve knowledge of the ranges and population sizes of Black-crowned Night Herons, Yellow-crowned Night Herons, American Bitterns, and Least Bitterns and will inform conservation and management decisions for these rare and declining wetland birds.

PACE Lab Herpetology Post-Doc heads to Arizona

Dr. Sarah Baker accepted a position as a herpetologist with the Arizona Game and Fish Department in October 2018.

Dr. Baker began at INHS as a graduate student conducting research on the Eastern Massasauga Rattlesnake. She was at the forefront of the discovery and subsequent research of Snake Fungal Disease in Illinois Massasaugas. During her 12 years here, she authored and co-authored several papers and collaborated with researchers across the country.

Sarah will remain an affiliate of INHS and we look forward to future collaborations.

UBAP staff presents at Ecological Society of America

UBAP Ornithologist Anastasia Rahlin presented a poster at the Ecological Society of America conference held in Portland, Oregon from August 6th-11th. The poster reported on the environmental DNA research being conducted in collaboration with Mark Davis and Matthew Niemiller to collect presence-absence data on cryptic rails in Northern Illinois. The project is testing environmental DNA for bird detection and comparing it to traditional playback surveys.
