The future of sustainable human health and agriculture rests on our ability to view microbial evolution as part of the solution rather than the problem. Kyle Walsh Pa Flip Flops Flat Sandals for Women,Summer Boho Tassel Pompom Beach Slipper shoes BrownThe Koskella lab  takes on this challenge by combining discovery-based science on plant microbiomes with hypothesis-driven experimentation.

We focus primarily on how plant-microbiome, plant-pathogen, and bacteria-phage interactions occur, both as model systems for understanding fundamental principles and with the aim of leveraging these findings for design of novel disease management strategies.

A brief introduction to the lab and our recent research:

I am an evolutionary ecologist interested in how species interactions influence genetic diversity within populations, diversity between populations, and species diversity at the community level. By combining evolutionary theory on coevolution, population dynamics, and infection genetics,Welcometoo 2019 Hot Plus Size Elegant Women Foldable Flat shoes Fashion OL Ladies Flats Round Toe Woman's Footwear Female A074Sperry Women's Seaside Nautical Perf shoesSwedish Flag Women'S Recreation Canvas Handbag For Shopping Big Shopping BagScience It's Like Magic But Real Women'S Leisure Canvas Sling Bag For Work Handbag I directly test the underlying assumptions and predicted outcomes of host-pathogen and microbial interactions through the lens of human health and agricultural sustainability.

My previous work was primarily focused on host – parasite coevolution; first between a smut fungus and a plant (e.g. New Candy color Women Pumps Shallow color Block Thick High Heels shoes Bowtie Pink Working shoes), then a trematode and a snail (e.g. AdeeSu Womens Cross-Body-Strap Platform Height Polyurethane Sandals), and most recently between bacteriophage viruses and the bacteria they infect, which are themselves parasites of plants (e.g. if phages are locally adapted to bacteria, Flats shoes Women Ballet Princess shoes for Casual Crystal Boat shoes Rhinestone Women Flats Plus Size Newand Meimeioo Women's Ballet Flats Comfort Soft Slip On Square Toe Dress shoes). The types of fundamental questions I’ve address are:

1) How do pathogens/parasites adapt to better infect their hosts? And at what scale / speed are they capable of adapting?

2) How do hosts respond to this adaptation (i.e. coevolve) and become more resistant to their local pathogens/parasites?

3) Can antagonistic coevolution lead to increased diversity? For example, do pathogens/parasites preferentially target common hosts (i.e. the hosts that are the most fit) and therefore impose a rare-host advantage?

and 4) Does this coevolution among hosts and parasites matter to human health, agriculture, and conservation? Can we use our understanding about when and how pathogens and commensals evolve to design better treatments and to predict and prevent the spread of diseases?

So far, the body of evidence produced by the scientific community over decades of work suggests that parasites can evolve rapidly and specifically to infect their hosts, but that this doesn’t always mean they get more harmful or even better at infecting.HANBINGPO Bling Women Sandals Summer Fashion High Heel Sandals Crystal Casual Ladies shoes High Heels Rhinestone Slippers Q409,bluee,7Skechers Womens Bobs Plush - Kitty Jam Flats There is also clear evidence that hosts respond by evolving increased resistance, and that this often comes at a cost such as decreased growth or reproduction. This ongoing coevolution, in which neither parasite nor host is winning the battle has been called ‘Red Queen’ dynamics, based on the idea from “Alice Through the Looking Glass” that you have to run as fast as you can just to stay in the same placeGilesJones Flats Loafers Women,Summer Hollow Round Toe Lace up Moccasins Ballet shoesSmile-bi Women Boots 2018 Winter shoes Women Plus Insole Snow Boots Fur Ankle Boots for Women.CoolBao Women Canvas Round Toe Lace up Flat Canvas shoes Oxford Boat shoesRob-Zombie- Classic women's Canvas Slip-Ons Loafer shoes Sneaker At last these ideas are beginning to be incorporated into the design and use of drug treatments (sometimes referred to as Darwinian Medicine) and used to build predictive models of disease spread in our increasingly-connected world. My work has taken advantage of a very powerful approach to address these questions by experimentally evolving hosts and parasites in the laboratory, ADELINA Women's Floral Patterned Boat Loafer shoes Driving Moccasin 39-Black 40 EU 8.5-9 USEdv0d2v266 Women Casual shoes Breathable Height Increasing Sneakers Fashion Swing Shake shoestherefore controlling for all the other “noise” out there in nature (Women Boots Mid-Calf High Wedge Heel Warm Fur Soft Female Winter Snow Botas).QARYYQ Rain Boots, Rain Boots, Men's and Women's shoes, Waterproof, Rain, Anti-Skid, Wear-Resistant, Thickened, Snow-Proof Outdoor Bicycle shoes Cover (color White-2pair, Size XL)Northside Womens Pioneer Wp-w Hiking Boot However,Crazy-Shop Winter Over The Knee Boots Women Thigh High Sexy Lace Up Woman Flat shoes Long BotaHANBINGPO Gladiator Bohemian Sandals Women Crystal Summer Slipper shoes Women Flatshoes Flip Flops 2019 I always try to go back to nature’s microcosm to find out whether what holds true in the lab can be used to explain what we see in the real world.Unm Women's Vintage Peep Toe Heels shoes
