This summer eastern Kansas has been in an extreme drought. But what exactly does it mean to be in a drought, and did you know that there are several types of drought often not discussed? Generally, a drought is a period when an area receives below-average amounts of rain/snow. Droughts can last months, years and even decades (decadal droughts are called “megadroughts”). However, not all droughts are equal and differ in their impacts on society, plants, animals, and the landscape. Continue reading “Drought And The Prairie”
A beautiful blue and green mass with stars covering its surface, the human papillomavirus (HPV) is ironically beautiful. Not only is HPV pretty, it is also very small. All viruses, like HPV, are small, consisting only of genetic material and protective coatings made of fats and proteins. Due to this simplicity, the only way viruses can replicate and spread is by infecting other organisms’ cells. Viruses are so reliant on their hosts that some have evolved to be entirely specialized on one species. In particular, HPV is dependent on humans to replicate.

Fish, believe it or not, need water. Though this may not be a shocking revelation, it does make predicting what might happen to fish when the waters they depend on disappear rather simple. Imagine being confined to a small, swelteringly hot room with a limited amount of oxygen to breathe that nearly disappears overnight. You cannot escape, and you realize that you are ill-equipped to survive very long under such conditions. That scenario does not sound very pleasant, does it? In the years ahead, scientists expect climate change to increase both the length and number of drought events here in the Kansas Flint Hills. But how will aquatic organisms like fish fare under these drier future climatic conditions? As the sweltering summer heat and the historic drought that accompanied it lingered on, this question spurred researchers at K-State to investigate.

Freshwater is necessary for human society in many ways, especially as a water supply for farming, industry, cities and towns. The most common way people have found to make water readily available is by building dams, which stop free-flowing streams and rivers to create reservoirs of standing water. While dams have been important for human population growth and major technological innovations, dams often negatively affect many of the animals and plants that inhabit rivers.

This post is a highlight of a research article recently published by K-State alum Dr. Kimberly O’Keefe and her PhD advisor, Dr. Jesse Nippert.
On the Biology Division office front desk sits a small bowl of candy. Students often grab one or two pieces on their way in and out of the office, as expected, but you would not necessarily expect a student to take the whole bowl. Likewise, you would not expect other organisms to use more resources than they need, not necessarily because they have manners, but because it is not efficient to gather more resources than necessary. Yet recent evidence suggests that in some grasslands, certain plants may be doing just that—absorbing more than they need to cripple their neighbors’ success. These greedy plants are not hoarding candy, but water, which is essential to life. Continue reading “Greedy Plants: Water use and nighttime transpiration in the tallgrass prairie”
When I was growing up, I really enjoyed “choose your own adventure” books. The adventures in these books would start out with the same problem and allow you to make decisions that would affect the story’s outcome from there. For instance, you might start out at the entrance to a cave and have to decide whether to go in or walk in the opposite direction. Typically, these different decisions would lead to different outcomes, although occasionally two or more stories would converge on the same ending. Continue reading “Different stories, same conclusion: how evolution is sometimes like a “choose your own adventure” book”
When is too much rain a bad thing? In eastern Kansas, we know that rain drives the productivity of crops and other plants, but we also understand that raging floodwaters can cause major damage. However, some ecosystems rely on enormous amounts of rain. In tropical rainforests, life thrives while receiving as much as seven times the average rainfall in Manhattan, Kansas. So can these tropical wet rainforests get too much rain? Continue reading “Science on Tap: Rain, migration, and dancing birds”
This post is the first of our new series covering Science on Tap. This monthly event, a part of Sunset Zoo’s Behind the Science initiative, is a gathering at the Tallgrass Taphouse during which a featured scientist shares their research and engages with the audience in a lively conversation about the topic. Hopefully you are able to grab a beer and join in on the conversation; if not, we’ll be here to provide a summary of the research that was shared!
Have you ever been in a room full of people and wondered whether another person in the room has the same birthday as you? The chances that one other person will share your birthday in a situation such as this is a question of probability, termed the birthday paradox. This statistics problem has been studied in detail, and the results are quite surprising. In a room containing 65 people, there are a total of 2,080 number of unique birthday pairs; quite a big number of interactions! And though it seems like 65 is not that many people, there is a 99.7% chance that two people share the same birthday in a group this big. The problem is finding a significant pair, two people with the same birthday, in a pool of insignificant ones.

Avoiding predators is always challenging, but it’s even harder in human altered landscapes where the escape routes may not be as plentiful as they used to.
Evading large predatory fish in highly disrupted waters is just one of the many challenges faced by the Topeka Shiner, a small, freshwater minnow that lives in prairie streams throughout the Mississippi River basin. This endangered species must also contend with both native and introduced predators, including the largemouth bass, a species favored by anglers.
The Topeka Shiner’s natural habitats have been significantly altered by human activities. Much of the area once covered by Kansas’s historic prairies has been converted to agricultural lands, and many landowners have dammed or dug out areas of stream to create small agricultural ponds. These ponds change and disrupt the habitats of freshwater fish, as do road crossings.
