Field drawing has long been used as a method of documentation and observation in the natural sciences. However, more technologically advanced documentation tools, perceived dichotomies between artistic and scientific capabilities, and low artistic confidence in both students and instructors have resulted in declining interest and usage of field drawing as a skill. Can the value of field drawing be revived? How can these mental barriers be challenged and overcome? Bethann’s been working hard to find out.

Popcorn accounts for a small portion of the corn grown in the United States. It is therefore important to protect popcorn varieties from cross-pollination with other field corn varieties. Up until now, genetic differences have protected popcorn from field corn cross-pollination. However, the introduction of certain Mexican maize varieties into the corn breeding pool for desirable traits has also introduced the potential risk for corn plants that are genetically compatible with popcorn cross-pollination.

Oysters are praised as ecosystem engineers, not only for their filter feeding, which draws particulate matter and nutrients out of the water, but also for their ability to create natural structures in the wild that can protect against storm surges on the coasts. But, as they expel excess nutrients that they don’t use, is there a potential for an environmental tradeoff, either in soil health or on the other creatures that live within these ecosystems? Chelsea Duball and her team studied oysters in Rhode Island...2020-06-1938 minField, Lab, EarthWater Retention Products on Home Lawns with Vikram Baliga“Evaluation of Water Retention Products to Conserve Urban Water Resources in Home Lawns” with Vikram Baliga.

Riparian buffers are areas of perennial vegetation planted around stream banks and other riparian zones to protect against soil erosion and nutrient leaching. However, tile drainage systems—piping laid under fields to keep them from becoming too saturated—are designed to bypass riparian buffers, leading to potentially harmful levels of nutrient leaching. Saturated Riparian Buffers are a relatively new conservation technique that aims to reduce those water quality issues by redirect...2019-08-1640 minField, Lab, EarthTree Harvesting, Biomass Removal, and Soil Nutrient Reserves with Dr. Dave Morris“Effects of Biomass Removal Levels on Soil Carbon and Nutrient Reserves in Conifer-Dominated, Coarse-Textured Sites in Northern Ontario: 20-Year Results” with Dr. Dave Morris Forest harvesting varies greatly from annual harvests of agricultural crops, with extended times between harvests, the amount of harvested material removed, and the degree of site disturbance. Trees can grow to impressive sizes, but can take up to 60 years or more to reach a merchantable size. Because of these factors, the potential impact of these forest harvest operations on the environmental conditions needed for successful tree regeneration and growth can be substantial.

Hydrology, put plainly, is the study of water: how it moves, where it goes, and what’s inside it. Hydrologists gather as much information as they can about water in order to understand current water trends and to predict potential water patterns in the future. In a changing climate, this is more crucial than ever. Using data from multiple networks of hydrological observatories, hydrologists gather information and create and test models surrounding questions such as: How will land use change affect water flux?

One of a farmer’s greatest enemies is a nemesis that they never even see. A nematode sounds like a ghastly swamp monster – in reality, it’s a microscopic worm that does some big time damage to soybean fields. These little guys love living in the soil and sucking on soybean roots. A bad infestation of soybean cyst nematodes can cost a farmer around 30 to 40% of his or her crop.

For good reason – even at low concentrations, mercury can do serious damage to neural networks and reproductive systems. However, we talk little of how the mercury gets in these fish in the first place.

Canada really cares about the future of canola. It has surpassed spring wheat as the dominant crop in Canada, covering 8.5 million ha of Canadian agricultural land. It is even named after Canada, as the word canola itself is a contraction of “Canada" and "oil”. However, climate change and increasing temperatures threaten Canada’s canola sector—which is why Agriculture and Agri-Food Canada has constructed a team of scientists to study the future of canola and Canada’s agricultural areas, which are projected to have a 3 to...2018-08-1728 minField, Lab, EarthInsect Pollinators and Confection Sunflowers with Dr. Rachel Mallinger“Benefits of Insect Pollination to Confection Sunflowers Differ Across Plant Genotypes” with Dr. Rachel Mallinger.
