"Toward Better Understanding of Terrestrial Processes through Long-Term Hydrological Observatories" with Dr. Heye Bogena.

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? Will climate change create conditions for more low or high flow events? How can forestation affect frequency of high flow events? They then use this information to create resources for natural resource managers, officials, and the public to make informed decisions. In this episode, we'll take a deeper look at how hydrological observatories are making strides in understanding water and its movement around the world.

We'll discuss:

• What's a catchment?
• What is the history of hydrological observatories?
• How do hydrological observatories communicate?
• Why should different disciplines of sciences collaborate with hydrology?

Precision Agriculture Basics with Dr. David Clay

Dr. David Clay, along with the precision agriculture community, are working like codebreakers to crack the secret to more efficient, more environmentally friendly farming. The key? Understanding variability.

Across any given farm field, there are many discrepancies in how given points of the field react to similar management practices. If farmers understand what causes those discrepancies, they can fine tune management in ways that can optimize fertilizer and pesticide use, inputs, and time. Getting this type of information used to mean extensive and costly soil sampling. Dr. Clay discusses how tech has made it possible to make great management decisions from data obtained miles above a farm.

• Learn about this as well as:
• What are the types of variability found in a field?
• Why does topography affect yield?
• How does the Dust Bowl impact us and the land today?
• What is soil's memory effect?
• What are zone sampling and grid sampling? Why is the difference important?
• How can one identify chlorophyll from miles away?

"Hand Planter for the Developing World: Factor Testing and Refinement" with Dr. Bill Raun

Across Central America, South America, and Africa, there are thousands of acres of land with slopes and landscapes that will never be suitable for mechanized agriculture. For hundreds of years, they have been planted by hand, a practice that continues today.

The problem is, as technology in chemical seed treatments has advanced, technology in hand-planting techniques has not, resulting in thousands of farmers' exposure to seed-friendly chemicals that can lead to sickness and even birth defects in humans.

After splitting much of his childhood and early career between North, South, and Central America and seeing the results of this exposure, Dr. Bill Raun decided it was time to do something about it. Working with engineering students and professors at Oklahoma State University, he has spent more than 20 years developing a new hand planter that will work with existing hand-planting techniques to increase yields and get good, chemically treated seed out of farmers' hands.

Listen now to learn:

• What are some of the problems Central American farmers face when using traditional hand-planting techniques?
• How can use of the hand-planter and modified hand-planting techniques double yields for developing world farmers?
• Why is anthropology so key in designing new tools, and how does human interaction affect design?

"Review: Sediment-Related Controls on the Health of the Great Barrier Reef" with Dr. Peter Hairsine.

In 2016, a catastrophic bleaching event killed off around 30% of the Great Barrier Reef's coral. The reef has been in a precarious spot for decades, but climate change and human-caused pollution have amplified the threats to its existence. Dr. Peter Hairsine is a scientist with The Fenner School of Environment and Society, The Australian National Univ., Canberra, Australia, working on the front lines of monitoring and researching the reef's responses to these changes, with an ultimate goal of preserving it as one of the world's richest and most unique ecosystems.

Join us as Dr. Hairsine and I discuss the stresses that the Great Barrier Reef (GBR) currently experiences. Warming ocean temperatures, deteriorating river water quality, and tropical storms all threaten the fragile coral that houses thousands upon thousands of native species. You'll learn the three ecosystems of reef within the GBR, as well as the sources of sediment and attached pollutants that currently feed into it.

Also in the episode:

• Why is the reef considered a "nutrient desert"? Why is that a good thing?
• What is a bleaching event? Why does it happen?
• How does a "plague" of starfish occur?
• How do reservoirs help trap sediment before it can reach the reef?
• What is an evidence based way of prioritizing the locations where rehabilitation money should be spent?

"Pyramiding of Alleles from Multiple Sources Increases the Resistance of Soybean to Highly Virulent Soybean Cyst Nematode Isolates" with Dr. Brian Diers.

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.

So how does one fight a nemesis that is too small to see? You build up a resistance. That's what Dr. Brian Diers is developing through his soybean breeding research. He's been working with crop wild relatives, soybean varieties, and plant breeders to identify sources of resistance and ways to incorporate that resistance into soybean.

This process is a race against time. Resistant soybean varieties are almost entirely from a single source. Nematodes are becoming more and more capable of overcoming this resistance.

Listen in to learn:

• How Dr. Diers team finds a gene location responsible for resistance
• How to visually identify nematode infestation
• How to create a genetic marker
• How a polymerase chain reaction is used in genetics research

"Yellow Perch (Perca flavescens) Mercury Unaffected by Wildland Fires in Northern Minnesota" with Dr. Randy Kolka and Trent Wickman.

We often hear of the dangers of mercury to pregnant women and children that require them to restrict fish consumption. 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.

The most common way mercury enters the ecosystem is through the burning of coal; however, it can also volatilize via prescribed and wild fires in forests. From there, it can redistribute into other parts of the ecosystem, such as lakes, and work its way into the food chain. This can hurt the animals that rely on lakes or the fish that live in them to survive. It can also hurt people. For Dr. Randy Kolka and Trent Wickman of the USDA Forest Service, who love the people and wildlife of Northern Minnesota – they had to know more.

They set up a study on two lakes – one that hadn't seen a fire in over 100 years and one that had a serious fire that covered over 99% of the watershed – and sampled soil, water, and fish to compare mercury levels.

In this episode, they discuss their experimental design, along with a breakdown of the realities of fieldwork. It can be tough carrying heavy equipment or samples of lakewater, let alone camping gear and food; they discuss how they made choices on what to bring, how samples were collected, and how they managed the logistics of the trips.

Tune in to learn this and more:

• How does one collect a water sample from a deep lake?
• What's a "crown fire" and why is it so dangerous?
• How is fire severity judged?
• Why perch?

"An Inventory of Crop Wild Relatives of the United States" with Dr. Stephanie Greene.

Crop Wild Relatives week is September 22 – 29, 2018!

Crops are vital to feeding an expanding world – and like anything incredibly important, they need to be protected from things like disease, environmental disaster, and anything else that can pose a real threat. The key to their protection? Unexpected heroes that could be growing in your back yard– wild varieties of domesticated crops called crop wild relatives.

Crop wild relatives are the close cousins of domesticated crops (think a poodle vs. a wolf). Often, these crops are well-adapted to their environment and can exhibit wild superpowers such as drought or disease resistance. And because they are so closely related to domesticated crops, scientists can cross them with crops that people rely on for food or other uses, such as wheat or blueberries. The result – stronger, healthier crops– and peace of mind that your favorite blueberry muffins will be available for years to come.

Dr. Stephanie Greene and seedbanks around the world have made it their mission to catalog, protect, and educate the public on these wild, unruly cousins of crops and how scientists use them to give our favorite crops super strength.

This year, for Crop Wild Relatives week, tune in to find answers to the following questions and more:

• What's the point of a gene bank?
• What type of traits are scientists looking for in crop wild relatives?
• How do they determine which ones are important?
• What's a gap analysis, and how is it done?
• Why is it so important that the public knows about crop wild relatives?

The Farm Bill with Dr. Julie McClure and Dr. Elizabeth Stulberg

If you have ever eaten food in the United States, you've been impacted by The Farm Bill, a mega-bill that is due for renewal in Congress this September. Although it heavily affects farmers, the Farm Bill covers a huge swath of topics: wildlife conservation, rural affairs, agriculture research, food stamps, and a lot more. If it seems like a big and overwhelming deal, that is because it is. Luckily, we have Drs. Elizabeth Stulberg and Julie McClure, two ASA-CSSA-SSSA science policy managers that are fluent in scientific research and the ins and outs of Washington politics to be our guides. For our membership, they work as translators between scientists and policymakers. Scientists want to know about relevant happenings in D.C. and new available funding opportunities; policymakers want to know new science that could impact their legislative districts.

We discuss the amazing history of the Farm Bill, how the bill will move through Congress this September, and what happens to the $1 trillion that is slated to be budgeted for this next Farm Bill. As it turns out, passing an important bill (especially a bill that affects so many) is hard! Put your learning caps on, because we're about to take a deep dive into the process of how a concept grows from idea into a large-scale part of our daily lives.

Tune in to learn:

• Why is the Farm Bill so huge?
• What does the Farm Bill have to do with The Dust Bowl?
• What's a congressional committee and what do the different committees do? How are committee assignments made?
• What's an authorization, and how is that different from an appropriation?
• What's mandatory funding, and why would a bill need it?
• Where are we are with the Farm Bill today?

Please note: At around 32:00 Dr. McClure says FFAR funds have to be matched by public funding, but in fact they must be matched by private (non-federal) funding.

"Simulated Canola Yield Responses to Climate Change and Adaptation in Canada" with Dr. Budong Qian.

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 3.5 °C increase in temperatures within the next 30 years.

Tune in to learn:

• What exactly is canola, and why does it matter?
• How Dr. Qian simulated the response of canola growth to future climate change scenarios
• Potential adaptations for canola to climate change

"Benefits of Insect Pollination to Confection Sunflowers Differ Across Plant Genotypes" with Dr. Rachel Mallinger.

Sunflowers are a hallmark of an American summer. They're grown for beauty, but they are also important industrial crops in America, grown for sunflower oil, for fresh eating (of the seeds), and for bird seed. And although we've slowly bred them to be more independent of pollinators, sunflowers still partner with bees. And not just honey bees. More often, they partner with native bees.

Did you know honey bees aren't even native to the U.S.? And while just as charismatic in their own way, native bees might not fit the usual description of a bee that we imagine. Most U.S. bees don't have a colony, don't have a queen, and don't have a hive that sits in a tree. And yet these mostly underground, solitary dwellers are the ones that are so important for sunflowers (and many flowers).

Dr. Mallinger's research looks at the fascinating relationship between these species – the confection sunflower and native bees. She wants to be able to measure this relationship. How do sunflowers benefit from pollination by bees?

Tune in to learn more about Dr. Mallinger's research and to find answers to these questions:

• What are the differences between a honey bee and a native bee?
• Why should we care about native bees?
• What is Dr. Mallinger's favorite type of bee?
• How does pollination increase the yield of sunflowers?
