About Me:

I am a broadly trained invertebrate ecologist and conservation biologist. Students in my lab have addressed questions related to the impacts of disturbance on invertebrate communities, food web interactions (such as forage availability for vertebrate wildlife), and conservation. Disturbance may occur naturally in a system or result from human activities such as tillage, prescribed burning, grazing, soil amendment, development, habitat fragmentation, compaction or invasive plant species. We are currently heavily involved in research focused on conservation of the federally endangered American Burying Beetle. If you are interested in invertebrate field ecology or behavioral ecology and would like to join our very “student-focused” research team please email me regarding your specific interests.

Projects currently underway in our lab:

  1. Expanded methodologies for long term monitoring of relocation survival and population density of federally endangered American Burying Beetle (Nicrophorus americanus) in Oklahoma, and surveys for potential re-introduction in central New York. ( duration Sep 2012- Dec 2015). Student researchers involved:

    b. Ben Derr, B.T. Wildlife Management SUNY Cobleskill
    c. Thomas Ferrari, M.S. candidate in Entomology and Plant Pathology, OSU
    d. Kyle Risser, Ph.D. candidate in Entomology and Plant Pathology, OSU
  2. The Effect of Preferred Arthropod Availability on Bobwhite Quail Nest Site Selection and Chick Survival (duration: July 2011- Dec 2014): This is a large, interdisciplinary project involving multiple collaborators and multiple states. Graduate students working on this project are evaluating the effects of a variety of factors that impact arthropod community composition within Beaver and Packsaddle Wildlife management areas of western Oklahoma. Studies focus on arthropod taxa known to be key forage species for juvenile quail. Oklahoma Dept. of Wildlife Conservation. Student researchers involved (from left to right above):

About Alex: I began my turfgrass career in Minnesota working at two private country clubs (Midland Hills C.C. and the White Bear Yacht Club) in the Twin Cities area. I graduated from the University of Minnesota in 1986 with a Bachelor of Science in Turfgrass Management. After graduating I became Assistant Superintendent at the White Bear Yacht Club. The next position I took was Athletic Field Manager at the University of St. Thomas in St. Paul Minnesota. Not feeling challenged in this job, I returned to the University of Minnesota and earned a M.S. degree through the Department of Horticultural Science (turfgrass). I stayed on at the University of Minnesota and worked as a junior scientist assisting with research and maintaining turfgrass plots and greenhouse facilities.

I left the University of Minnesota after working there for two years. I returned to the golf industry taking a position at River Oaks Golf Course, a municipal facility. I worked at River Oaks for five years and kept looking at teaching positions that were available.

After much searching I finally found my niche in academia. I was hired as the Program Director to develop and teach in a turfgrass management program at the University of Minnesota, Crookston. While teaching and developing the turf program I returned to graduate school and earned a Ph.D. through the Department of Plant Pathology at the University of Minnesota. My research included field studies in mowing practices to reduce dollar spot on creeping bentgrass. I chose this topic to research because utilizing these practices can help reduce the need for fungicide applications. I am passionate about reducing chemical inputs and using IPM practices to provide high quality turf with minimal environmental impact.

In 2006 I was hired by SUNY Cobleskill to replace Mr. Bob Emmons, an icon in turfgrass education. I am excited to be here because I really enjoy teaching and advising. I also love the hand on opportunities we are able to give our students.

Mowing Strategies and Dew Removal to Minimize Dollar Spot on Creeping Bentgrass
Alex Ellram, Brian Horgan, Brent Hulke

Crop Science – CROP SCI 01/2007; 47(5). DOI:10.2135/cropsci2006.10.0649
ABSTRACT Dollar spot (DS) disease (caused by Sclero- tinia homoeocarpa F.T. Bennett) on bentgrass (Agrostis spp.) can be greatly reduced by imple- menting mowing and other cultural practices that reduce leaf wetness duration (LWD). Field studies were conducted in 2004 and 2005 to discern the effects of dew removal time (mow- ing at 0400, 1000, or 2200 h), method of dew removal (mowing with sharp or dull mower or squeegee), and frequency of dew removal (daily or alternate days) on the incidence of DS on fairway height (16 mm) creeping bentgrass (Agrostis stolonifera L.). The severity of DS was studied in laboratory experiments with 6, 12, and 18 h LWD. Dollar spot incidence on fi eld test plots was lowest when mowing treatments were conducted at 0400 h. In addition plots mowed at 2200 h had signifi cantly lower DS incidence than plots mowed at 1000 h. Mowing with either a sharp or dull reel mower proved more effective in reducing DS than alternating mowing with a squeegee for dew removal. Dull mower blades were as effective as sharp mower blades in reducing DS in our fi eld studies. Dollar spot incidence was also lower when dew was removed daily than when dew was removed on alternate days. Mowing at 0400 h daily was the most effective treatment for reducing DS on creeping bentgrass plots in both 2004 and 2005. In laboratory experiments, DS lesion size increased as LWD increased. Specifi cally, dis- ruption of leaf moisture after 6 h of uninterrupted LWD appeared to be most effective in reducing DS lesion diameter.
