Howdy Folks,
<div><br>
</div>
<div>We have no Ecolunch this week, nor next week (because next Wednesday is a holiday). We will have Ecolunch seminars during the last two weeks of the semester after Thanksgiving, however, so stayed tuned for those!</div>

<div>Also, John Schenk in PBIO is giving a talk this Friday at 11:50 in Porter 104. That information is below. See you there!</div>
