封面图片：Fluorescent micrograph of Epichloë hyphae growing endophytically within the intercellular spaces ola grass seedling. The fungus exhibits a high branching freguency within the apical meristem of the plant (center). incontrast, hyphae are characteristically alianed parallel with the eaf axis and exhibit ittle to no branchina when thefunaus colonizes leaf primordia and axillary buds (either side of the meristem). The fungal strain in this image wastransformed to express the green fluorescent protein (GFP) and was observed using a confocal laser microscope. ltis now standard practice for ryegrass seed sold in New Zealand to carry a proprietary strain of endophvte to conferbiotic and abiotic stress resistance while reducing/minimizing harmful effects on livestock, lmage courtesy of StuartCard (David E.

英文标题：Development of long-term spatiotemporal continuous NDVI products for alpine grassland from 1982 to 2020 in the Qinghai–Tibet Plateau, China
作者：Xiali Yang, Xiaodong Huang, Ying Ma, Yuxin Li, Qisheng Feng, Tiangang Liang
第一作者：Xiali Yang
通讯作者：Xiaodong Huang
A long time-series monthly Normalized Difference Vegetation Index (NDVI) data set with a spatial resolution of 250m from 1982 to 2020 was developed by combining MODIS (Moderate Resolution Imaging Spectroradiometer) and AVHRR (Advanced Very High-Resolution Radiometer) time-series NDVI products using the Random Forest model. The generated product is reliable in accuracy and has great potential for grassland dynamic monitoring in the Qinghai-Tibet Plateau.

英文标题：Stability and purity of selected ryegrass Epichloë endophytes in New Zealand dairy pastures
作者：David E. Hume, Dongwen Luo, Grant M. Rennie, Warren M. King, Anna L. Taylor, Marty J. Faville, Katherine N. Tozer
第一作者&通讯作者：David E. Hume
Ryegrass tiller sampling is performed to determine Epichloë fungal endophyte infection and strain of Epichloë, to ensure that sown selected endophytes are delivering pasture production, animal health, and productivity benefits for New Zealand dairy farmers.

英文标题：Challenges in bermudagrass production in the southeastern USA
作者：Lisa L. Baxter, William F. Anderson, Roger N. Gates, Esteban F. Rios, Justin C. Burt
第一作者：Lisa L. Baxter
通讯作者：Lisa L. Baxter
The bermudagrass stem maggot is one of the most persistent pests in the southeastern USA. The damage is evident by chlorosis of the top two to three leaves of the pseudostem. Fine stem cultivars (left) are more susceptible than coarse stem cultivars (right).

英文标题：Fecal microbiota reveal adaptation of herbivores to the extreme environment of the Qinghai–Tibet Plateau
作者：Hao Zou, Qi Li, Jie Liu, Xiangtao Wang, Qun Gao, Yunfeng Yang, Xinquan Zhao
第一作者：Hao Zou
通讯作者：Jie Liu、Xinquan Zhao
Our study revealed that nonruminant Kiang had lower gut microbiota diversity than ruminant Chiru and Yak and that gut microbiota have more exclusive bacteria than fungi and tended to co-occur. Moreover, gut bacteria assemble stochastically, but gut fungi deterministically, except in Chiru.

英文标题：Grassland management intensity determines root development, soil structure, and their interrelationship: Results of a regional study of Leptosols in the Swabian Alps
作者：Katrin Kuka, Monika Joschko
第一作者&通讯作者：Katrin Kuka
The way we manage grasslands affects how the soil and roots behave. Our study using X-ray microcomputed tomography shows that especially fertilizers and mowing have a strong impact on root growth and soil structure. Understanding this helps to develop better land strategies that balance productivity with maintaining soil health.

英文标题：Systems management strategies for increasing alfalfa use in warm-humid regions
作者：Jennifer J. Tucker, Mary K. Mullenix, Esteban Rios, Daniel Basigalup, J. H. Bouton
第一作者：Jennifer J. Tucker
通讯作者：Mary K. Mullenix
Popular press summary: Success stories of alfalfa use in the Southeast United States and Argentina demonstrate the potential for expansion of planted area of alfalfa in subtropical and tropical regions of the world. This may improve forage production, nutritive value, and ecosystem services of livestock-forage operations in these regions.

英文标题：Perennial grass and herb options to extend summer–autumn forage in a drought-prone temperate environment
作者：Rebecca S. Stutz, Joanne De Faveri, Richard A. Culvenor
第一作者&通讯作者：Rebecca S. Stutz
Pasture quality and quantity limit summer–autumn livestock production in drought-prone temperate environments. We evaluated summer-active perennial grasses and herbs over the warm season in south-eastern Australia. Lucerne and chicory consistently showed high persistence, productivity and nutritive value. Digit grass, cocksfoot, tall fescue, perennial ryegrass, prairie grass and plantain also showed potential.
