After sorting and prepping her catch, she photographed the specimens with the college\u2019s research-grade JEOL JSM-6100 \u2019scope (which you can pick up for around $35,000, used).<\/p>\n<p>She chose the Puddle project after noticing an irony. \u201cStudents love the Puddle \u2014 we\u2019re like, \u2018Woo-hoo! Puddle Jump!\u2019 \u2014 but we don\u2019t really know anything about it,\u201d she says. \u201cIt was fun for me to get my hands dirty and learn about the Puddle from a scientific point of view.\u201d<\/p>\n<p>Nothing she found in her catch particularly surprised her or Bates\u2019 biologists, but that was the fun part, \u201cfinding both concrete, recognizable things\u201d and a diversity of creatures. She expected lots of copepods (they\u2019re a dime a dozen in freshwater ponds) but the fish and dragonfly larvae fell into that \u201cwell, lookee here\u201d category.<\/p>\n<p>On one level, knowing how to use a scanning electron microscope is just another helpful skill for a science major. On another, it did remove Schultz\u2019s safety net, bringing her closer to what she is now: a confident bio major capable of doing original research. \u201cWhen you have trouble in a lab, a lot of times the teacher can come over and magically make it go away,\u201d she says. \u201cWith this project, I had to work through things myself.\u201d<\/p>\n<p>For her senior thesis, Schultz looked at Lyme disease and whether catbirds can be \u201creservoirs,\u201d meaning a carrier of the disease-causing Borrelia bacteria, like deer and rodents.<\/p>\n<p>Catbirds are an intriguing research subject because their migratory range includes Canada, \u201cwhere new Lyme disease foci have been found,\u201d Schultz says.<\/p>\n<p>Lyme disease is spread by ticks that feed on carriers and, ultimately, on humans. As recently as 1990, disease-carrying ticks were nearly nonexistent in Canada, but by 2020 are expected to be found in 80 percent of populated Canadian areas, according to a recent study authored by Canadian researchers.<\/p>\n<div id=\"attachment_10249\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.bates.edu\/magazine\/files\/2012\/09\/E4-120223_schultz_9260.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10249\" class=\"size-large wp-image-10249\" title=\"Hannah Schultz '12.
