    INHS researchers reveal “virgin birth” in a crocodile

    In a recent study published in the journal Biology Letters, this is the first known instance of a crocodile virgin birth, but virgin births (parthenogenesis) have been recorded in fish, birds, lizards, and snakes. Parthenogenesis is a natural form of asexual reproduction in some animals where viable offspring are produced from an otherwise unfertilized egg. Mark Davis, a conservation biologist at the Illinois Natural History Survey (INHS) at the Prairie Research Institute (PRI) and co-author on the study helped examine the crocodile fetus' genomic makeup, ultimately discovering that the fetal genome resulted from reproduction without a male crocodile’s genetic contribution.

  • INHS botanists train volunteers at Midewin

    INHS botanists (Rick Phillippe, Paul Marcum, Brenda Molano-Flores, Jason Zylka, Jamie Ellis, and Mary Ann Feist) conducted a one-day vegetation monitoring workshop at the Midewin National Tallgrass Prairie, Will Co. Illinois May 19, 2009. A total of 16 volunteers attended the training. The ultimate goal of the workshop was to give volunteers real life experience in quantitative vegetation data collection and analysis. During the morning, volunteers were shown how to set up transects and plots and to determine percent cover for species and functional groups. During the afternoon, volunteers learned how to analyze and interpret the data they had collected. Volunteers expressed that knowing the dos and don’ts of collecting field data will be extremely helpful when they assist Midewn staff during vegetation sampling. They also commented that, although somewhat overwhelming, they now know how the data they will collect will be used to make management recommendations at the site. This event was sponsored by the Nature Conservancy and the Midewin National Tallgrass Prairie.

  • INHS botanists reconstruct 226 year history of fire in Southern Illinois

    By looking at the scars in the growth rings of 36 old-growth post oak trees, INHS botanist Greg Spyreas, affiliate John Ebinger and Illinois State Museum botanist William McClain found that there had been more than 100 fires in Southern Illinois between the 1770s and 1996. This repeated burning stabilized prairies and kept the woodlands open until the mid-1800s when fires appear to have been suppressed by the settlers in the area for a 30 year period. Fire suppression altered the plant community by allowing fast-growing, shade-loving species to survive. The study was published in the journal Castanea. Read news coverage of the story by the Science BlogScience Codex, and Earth Times.
