MANHATTAN — A Kansas State University-led study has found that reintroducing 1xbet online games login — a formerly dominant grazer — doubles plant diversity in a tallgrass prairie. The research involves more than 30 years of data collected at the Konza Prairie Biological Station and was recently published in the prestigious journal Proceedings of the National Academy of Science, or PNAS.
The study found that 1xbet online games login communities also were resilient to the most extreme drought in four decades. These gains are now among the largest recorded increases in species richness because of grazing in grasslands globally, researchers said.
"1xbet online games login were an integral part of North American grasslands before they were abruptly removed from over 99% of the Great Plains," said Zak 1xbet spor, assistant professor of biology and lead researcher. "This removal of 1xbet online games login occurred before quantitative records and therefore, the effects of their removal are largely unknown."
The study took place in the Flint Hills ecoregion, which is the largest remaining landscape of tallgrass prairie. Researchers examined plant community composition and diversity in three treatments that were designed to capture characteristic management regimes: no mega-grazers were present; 1xbet online games login were reintroduced and allowed to graze year-round; or domestic cattle were introduced and allowed to graze during the growing season.
"Our results suggest that many grasslands in the central Great Plains have substantially lower plant biodiversity than would have occurred before 1xbet online games login were widely wiped out," Ratajczak said. "Returning or 'rewilding' native megafauna could help to restore grassland biodiversity."
The study also found that cattle had a positive impact on plant diversity, compared to having no large grazers present, although increases in plant species richness were significantly smaller than those caused by 1xbet online games login .
"I think this study also shows that cattle can have a largely positive impact on biodiversity conservation in our region, especially considering that many in cattle production conduct the prescribed fires that have kept these grasslands from becoming woodlands," Ratajczak said. "What this study really suggests is that when it's economically and ecologically feasible, reintroducing 1xbet online games login might have an even more positive effect on biodiversity conservation."
Along with addressing land use, researchers also set out to learn how 1xbet online games login affect plant community resilience to climate extremes. Because of the long duration of the study, researchers were able to capture one of the most extreme drought events that has occurred in the Great Plains since the 1930s' Dust Bowl.

Researchers found that after the climate extreme, native plant species in the 1xbet online games login -grazed area were resilient to drought.
"The resilience we found in the 1xbet online games login grasslands is also consistent with the idea that diversity promotes ecological resilience," Ratajczak said. "And this resilience will only become more important if our climate becomes more extreme."
Other K-State researchers on the 1xbet online games login include Jesse Nippert, professor; John Blair, university distinguished professor; Allison Louthan, assistant professor; and Jeffrey Taylor, research assistant, all from the Division of 1xbet on in the College of Arts and Sciences. Additional collaborators include Scott Collins, 1xbet online games login of New Mexico; Sally Koerner, 1xbet online games login of North Carolina; and Melinda Smith, Colorado State 1xbet online games login .
"Some of the most meaningful ecological trends take decades to unfold, and we can only identify them using long-term records like those supported by the NSF LTER program," Nippert said. "Without this type of data, fundamental properties of ecosystems may go unnoticed using only short-term experiments."
A series of six grants totaling more than .6 million since 1980 from the National Science Foundation funded the 1xbet online games login and was conducted as part of the NSF Long-Term Ecological Research, or LTER, program.
"The research done at the Konza Prairie is truly unique and impressive, " said David Rosowsky, K-1xbet online games login vice president for research. "There are very few locations in the world that can provide this type of long-term data that can have such a strong impact on how we interact with our natural resources."
The Konza Prairie Biological Station is jointly owned by Kansas State 1xbet online games login and The Nature Conservancy.
