9 days, 3 conferences, 8 talks, 2 posters

It’s been a busy week of sharing science for members of the PACE lab.

The Chicago Wilderness Wildlife Committee Meeting was held at Lincoln Park Zoo on February 19th:

 

Tara Hohoff presented “The status of Illinois bats five years after confirmation of white-nose syndrome,” using data from her work with the Illinois Bat Conservation Program and the Urban Biotic Assessment Program monitoring for the Illinois Tollway.

 

Joshua Sherwood presented “Assessing the distribution and habitat of Iowa Darters (Etheostoma exile) in Illinois,” with co-authors Andrew Stites, Jeremy Tiemann, and Michael Dreslik. This work changed the way people look for the Iowa Darter.

 

Jason Robinson presented “Patterns of abundance and co-occurrence of bumblebees associated with the Rusty Patched bumblebee.” RPBB is a federally protected species found in northeastern Illinois that has experienced a decline in its range.

 

Jason Ross presented “Demographic influence of head-starting on a Blanding’s Turtle (Emydoidea blandingii) population in DuPage County, Illinois,” with co-author Michael Dreslik, discussing what amount of head-starting is needed to keep this population viable

 

The  2019 Wild Things Conference was held in Rosemont on February 23rd:

Tara Hohoff, representing the Illinois Bat Conservation Program, presented a poster “Year Three of the Illinois Bat Conservation Program.”

Anastasia Rahlin co-presented “Secretive Marsh Birds in the Big City.” with Audubon collaborator Stephanie Beilke on their ongoing work using playback to detect 17 focal wetland bird species in northeast Illinois and southeast Indiana. Soras were the most commonly detected species which was surprising/unexpected since Marsh Wrens and Swamp Sparrows are expected to be more common, and Little Blue Herons and Yellow-headed Blackbirds were the least detected which was pretty expected due to their declines. Future directions include creating species-specific occupancy models to better understand how our focal species respond to urbanization and presence of different wetland types at three different spatial scales.

Josh Sherwood presented “Current status of Bigeye Chub (Hybopsis amblops) in Illinois”.

Sarah Douglass presented “A preliminary analysis of mussel population dynamics in the Kishwaukee River.”

Jeremy Tiemann presented “Pulling the plug – Results of the fish and mussel salvage following the removal of the Danville Dam on the Vermilion River.”

Andy Stites presented a poster “Fecundity estimates of the Gravel Chub Erimystax x-punctatus

The Enigmatic Asian Clam

UBAP Malacologists Sarah Douglass and Jeremy Tiemann wrote an article for the Fall 2018 issue of Illinois Audubon: “The Enigmatic Asian Clam.” Asian Clams are an invasive species that became established in the Midwest in the 1960s. Douglass and Tiemann identified an unknown species of Asian Clam found in the Illinois River in 2015 and have been studying its distribution. They plan to examine the effect of Asian Clams on the growth of native mussels in Illinois streams.

Iowa Darter might not be as rare as believed

netting in ditchUBAP Ichthyologist Andrew Stites wrote a field account for the Illinois News Bureau’s Behind the Scenes to accompany a recent paper by Josh Sherwood, Andrew Stites, Michael Dreslik, and Jeremy Tiemann.

The paper, “Predicting the range of a regionally threatened, benthic fish using species distribution models and field surveys” developed a species distribution model for the state endangered Iowa Darter, after finding it in several new locations. This work was sponsored by the Illinois Tollway.

Hourly Research Assistant needed

A technician is sought to collect demographic data on amphibians collected from drift fence arrays surrounding vernal wetlands in central Illinois and reptiles from cover board arrays in old field and prairie habitats in central and northern Illinois. The technician will work independently and with others to collect data on amphibian and reptile demographics (identify, count, weigh, mark, and measure species). Records data manually and electronically into a database using a tablet. Prepares, under supervision, data summaries and quarterly reports. The technician will be responsible for decontamination of sampling equipment and boots, maintenance of equipment and fences, data entry, data management, tissue collection, amphibian and reptile marking and operate a variety of hand tools, electronics, and mechanical equipment such as 4WD vehicles and Utility Terrain Vehicles.

Work is performed in prairie and wooded environments where there is exposure to extremes of weather and temperature. The work requires moderate to strenuous physical exertion such as long periods of standing, walking over rough, uneven, rocky, steep, and muddy surfaces; bending, crouching, stretching, lifting, and carrying up to 40 lbs. Long hours in the field should be expected and some work on weekends may be required. Duration of the season will be from mid-January through August 2019.

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.

INHS Herpetologists Present at Venomous Herpetology Symposium

Members of the Population and Community Ecology and Herpetology labs here at the INHS gave several presentations at the first Venomous Herpetology Symposium in Miami, Florida, at Zoo Miami from September 8th-9th. The work showcased the diversity of projects on venomous snakes the graduate and undergraduate students in both labs are working on. Recent graduate Yatin Kalki had received a travel award to attend and present at the symposium.

It’s Mussel Time!

August 2018 marks the 4th year of the long term mark recapture movement study of mussels in the Kishwaukee River, led by malacologist Sarah Douglass. In addition to the staff from INHS, local forest preserve districts and IDNR, this year we were joined by several dedicated high school students and their teacher.

Earlier this year, Douglass came across a poster at the Freshwater Mollusk Conservation Society Mollusk Health & Disease Workshop that immediately caught her attention. The poster “A Comparison of Substrate Preferences for Native and Invasive Mussel Populations in the Kishwaukee River,” was presented by two students from an environmental science class at Sycamore High School. Led by teacher Scott Horlock, the “Watershed” class studies the South Branch of the Kishwaukee River to learn ecological lessons in a real world setting.

Always eager to inspire the next generation, Douglass invited Horlock and his students to join in the annual survey conducted on the Kishwaukee River. Despite it being summer break, Horlock accompanied a small group of students to the study site each day to learn about the sampling methods being used and become more comfortable with mussel species identification.

tree and rain in riverEven with a bit of rain, the river was what Douglass referred to as “nearly prime” for sampling. Like last year, we set out into the river, each claiming one of the 10m transects marked off by orange flagging tape. We waited for the timer to yell “Start!” stuck our heads in the water and fingers in the substrate to locate as many mussels as we could before hearing “Time!” measuring shellsAfter each timed survey we’d head back to our station under the bridge with bags of mussels to be marked and measured, gently ribbing each other about who found the most or best mussels.

Teams assembled to tag and measure all of the mussels, being careful to keep the mussels from each transect separated to return to their locations. The students joined in, eager to learn more about the mussels they had collected. While cleaning and tagging the shells, the malacologists pointed out the subtle differences measuring shellsbetween similar species. With each batch, the students (and other non-malacologists) became more confident in their skills.

Over the course of the three days, we found over 600 mussels, representing 17 species. Many of the individuals collected already had a color coded tag from a previous year, which is imperative to monitor the survival and movement of mussels in the stream. We added 4 new species to our list of live species this year: Fawnsfoot, Creek Heelsplitter, Threeridge, and Round Pigtoe. We also found one shell of a Pistolgrip, a species we hope to find live individuals of in future surveys.
