Diverse ecological functions and the convergent evolution of grass awns. [PDF]
Am J Bot, 2022 Abstract The awn of grasses is a long, conspicuous outgrowth of the floral bracts in a grass spikelet. It is known to impact agricultural yield, but we know little about its broader ecological function, nor the selective forces that lead to its evolution. Grass awns are phenotypically diverse across the extant ~12,000 species of Poaceae. Awns have been

Stronger fertilization effects on aboveground versus belowground plant properties across nine U.S. grasslands. [PDF]
Ecology, 2023 Abstract Increased nutrient inputs due to anthropogenic activity are expected to increase primary productivity across terrestrial ecosystems, but changes in allocation aboveground versus belowground with nutrient addition have different implications for soil carbon (C) storage.

Does responsiveness to arbuscular mycorrhizal fungi depend on plant invasive status? [PDF]
Ecol Evol, 2017 After controlling for phylogenetic similarity, we found no evidence that invasive taxa responded differently to mycorrhizas than other taxa. Although it is possible that mycorrhizal responsiveness contributes to invasiveness in particular species, weak mycorrhizal responsiveness may not be a general mechanism of plant invasion.

Availability of lesser prairie‐chicken nesting habitat impairs restoration success
Wildlife Society Bulletin, Volume 46, Issue 5, December 2022., 2022 Translocated lesser prairie‐chickens avoid areas on Cimarron and Comanche National Grasslands, which were strongholds for these birds in the 1980s and 1990s. Vegetation surveys suggest that these areas no longer provide nesting habitat required for this population to return to historic levels.

Applied Vegetation Science, Volume 25, Issue 2, Page 1-11, April/June 2022., 2022 We evaluated the functional characteristics of plant communities along the abundance gradient of Sporobolus cryptandrus, a C4 bunchgrass, in its both native North American and recent non‐native European ranges. We found that Sporobolus invasion in Europe leads to impoverishment of the host communities and compromises the biomass and floral resource ...

Exploring discrepancies between in situ phenology and remotely derived phenometrics at NEON sites
Ecosphere, Volume 13, Issue 1, January 2022., 2022 Abstract In recent decades, the use of satellite sensors, near‐surface cameras, and other remote methods for monitoring vegetation phenology at landscape and higher scales has become increasingly common. These technologies provide a means to determine the timing of phenophases and growing season length at different spatial resolutions; coverage that is

Different Aspects of Weed Management in Maize (Zea mays L.): A Brief Review
Advances in Agriculture, Volume 2022, Issue 1, 2022., 2022 Maize yield and weed concentration have a long history of reciprocal correspondence. The maize crop plant and weed species compete ruinously for nutrients, space, light, and water essential for their progress and advancement. The losses due to weed and methodologies of weed management have been discussed in this review.

Ecosphere, Volume 12, Issue 9, September 2021., 2021 Abstract Fire exclusion and mismanaged grazing are globally important drivers of environmental change in mesic C4 grasslands and savannas. Although interest is growing in prescribed fire for grassland restoration, we have little long‐term experimental evidence of the influence of burn season on the recovery of herbaceous plant communities, encroachment

Classification of forest and shrubland vegetation in Mediterranean Turkey
Applied Vegetation Science, Volume 24, Issue 2, April/June 2021., 2021 Mediterranean Turkey comprises three vegetation belts: 1) thermo‐ and meso‐mediterranean, with coniferous (Pinus brutia, Pinus pinea) and sclerophyllous forests, as well as macchia, garrigue and phrygana (red dots), 2) supra‐mediterranean, with Pinus nigra, thermophilous oaks and Ostrya carpinifolia forests, and forests of temperate species (yellow ...

Remote Sensing in Ecology and Conservation, Volume 6, Issue 3, Page 344-353, September 2020., 2020 We derived a regression model to predict community leaf dry matter content (LDMC) from remote measurements of canopy reflectance, then used the model to determine how community LDMC interacts with inter‐annual variation in precipitation to influence grassland biomass production.
