Biocrusts do not differentially influence emergence and early establishment of native and non‐native grasses

Ecosphere, 2021
Biological soil crusts (biocrusts) cover the soil surface of global drylands and interact with vascular plants. Biocrusts may influence the availability and nature of safe sites for plant recruitment and the susceptibility of an area to invasion by non ...

Grassification and Fast-Evolving Fire Connectivity and Risk in the Sonoran Desert, United States

Frontiers in Ecology and Evolution, 2021
In the southwestern United States, non-native grass invasions have increased wildfire occurrence in deserts and the likelihood of fire spread to and from other biomes with disparate fire regimes. The elevational transition between desertscrub and montane

Impact of Nigrospora oryzae-Derived Natural Products on Photosynthesis and Oxidative Stress in Eichhornia crassipes. [PDF]

Physiol Plant
Abstract Interest in natural herbicides has been growing due to government policies restricting synthetic herbicide use in many countries. In that regard, this study investigates the potential of Nigrospora oryzae extract as a natural herbicide against the aquatic invasive weed Eichhornia crassipes.

Spittlebug and Buffelgrass Responses to Summer Fires in Mexico [PDF]

Journal of Range Management, 1999
Summer burning was used to reduce spittlebug (Aeneolamia albofasciata Lall.) populations in buffelgrass [Cenchrus ciliaris (L.) Link] on the Carbo Livestock Research Station in Sonora, Mexico. Five treatments included (1) an untreated control; (2) burning 7-14 days before the summer rains when the insect and the plant were inactive; (3) burning after ...

Invasive buffelgrass detection using high‐resolution satellite and UAV imagery on Google Earth Engine

Remote Sensing in Ecology and Conservation, 2019
Methods to detect and monitor the spread of invasive grasses are critical to avoid ecosystem transformations and large economic costs. The rapid spread of non‐native buffelgrass(Pennisetum ciliare) has intensified fire risk and is replacing fire ...

Predicting Buffelgrass Survival across a Geographical and Environmental Gradient [PDF]

Journal of Range Management, 1995
This research was designed to identify relationships between T4464 buffelgrass (Cenchrus ciliaris L.) survival and climatic and soil characteristics. At 167 buffelgrass seeding sites in North America we collected climatic and soils data where the grass: 1) persisted over time and increased in area covered (spreads), 2) persisted over time but does not ...

Molecular characterization of new Buffelgrass (Cenchrus ciliaris) genotypes

Plant Omics, 2020
Buffelgrass (Cenchrus ciliaris L. Link) is an African agamospermous grass that has been widely introduced into arid regions of the world to improve rangelands for cattle production and as a result, it has invaded adjacent habitats. Cenchrus ciliaris is apomictic, a condition that is normally associated with low genetic variation within populations, but
