Abstract Background Subacute ruminal acidosis (SARA) is a metabolic disorder often observed in high-yielding dairy cows, that are fed diets high in concentrates. We hypothesized that circulating miRNAs in blood of cows could serve as potential candid

Abstract Agrivoltaic (AV) systems are designed to coproduce photovoltaic (PV) energy on lands simultaneously supporting agriculture (food/forage production). PV infrastructure in agroecosystems alters resources critical for plant growth, and water‐

Compound hydroclimatic extremes in a semi-arid grassland: Drought, deluge, and the carbon cycle

Autor: David L. Hoover, Olivia L. Hajek, Melinda D. Smith, Kate Wilkins, Ingrid J. Slette, Alan K. Knapp

Publikováno v: Global change biologyREFERENCES. 28(8)

Climate change is predicted to increase the frequency and intensity of extreme events including droughts and large precipitation events or "deluges." While many studies have focused on the ecological impacts of individual events (e.g., a heat wave),

Different Temporal Stability and Responses to Droughts between Needleleaf Forests and Broadleaf Forests in North China during 2001–2018

Autor: Guodong Yin, Xiran Li, Olivia L. Hajek, Muxing Liu

Publikováno v: Forests
Volume 12
Issue 10
Forests, Vol 12, Iss 1331, p 1331 (2021)

Droughts can affect the physiological activity of trees, damage tissues, and even trigger mortality, yet the response of different forest types to drought at the decadal time scale remains uncertain. In this study, we used two remote sensing-based ve

Shifting seasonal patterns of water availability: ecosystem responses to an unappreciated dimension of climate change

Autor: Olivia L. Hajek, Alan K. Knapp

Publikováno v: The New phytologistReferences. 233(1)

Seasonal patterns of water availability can differ dramatically among ecosystems, with well-known consequences for ecosystem structure and functioning. Less appreciated is that climate change can shift the seasonality of water availability (e.g. to w

Fire frequency influenced grazed grasslands' resistance and resilience to extreme drought

Autor: Kate Wilkins, Xiran Li, Jillian LaRoe, Olivia L. Hajek, Alan K. Knapp, Melinda D. Smith

Grasslands provide critical ecosystem functions and services globally, including forage production for livestock and other animals. As frequency and intensity of disturbances, including fire and drought, are increasing globally, grasslands and the se

Rodent seed predators and a dominant grass competitor affect coexistence of co‐occurring forb species that vary in seed size

Autor: Dean E. Pearson, Karyn L. Hajek, Philip G. Hahn, John L. Maron

Publikováno v: Journal of Ecology. 106:1795-1805

Propagule size and number often vary by several orders of magnitude among co‐occurring plant species. Explaining the maintenance of this variation and understanding how propagule size contributes to coexistence remain a central challenge for commun
