Mass mortality of saguaros (Carnegiea gigantea) from windthrow: A rare, demographic disturbance in a desert ecosystem

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to

In Silico and Fluorescence In Situ Hybridization Mapping Reveals Collinearity between the Pennisetum squamulatum Apomixis Carrier-Chromosome and Chromosome 2 of Sorghum and Foxtail Millet. [PDF]

open access: yesPLoS ONE, 2016
Apomixis, or clonal propagation through seed, is a trait identified within multiple species of the grass family (Poaceae). The genetic locus controlling apomixis in Pennisetum squamulatum (syn Cenchrus squamulatus) and Cenchrus ciliaris (syn Pennisetum ...

Effects on the compressive strength of cement-stabilized rammed earth blocks with varied content of buffelgrass-based fibers in wet-dry conditions

open access: yesFrontiers in Built Environment
Stabilized rammed earth blocks have been an alternative building material around the world due to their cost efficiency, low embodied energy, and environmental footprints. However, the lower compressive strength and resistance to wearing limits their use

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

Feasibility of Invasive Grass Detection in a Desertscrub Community Using Hyperspectral Field Measurements and Landsat TM Imagery

open access: yesRemote Sensing, 2011
Invasive species’ phenologies often contrast with those of native species, representing opportunities for detection of invasive species with multi-temporal remote sensing.

Developing an expert elicited simulation model to evaluate invasive species and fire management alternatives

open access: yesEcosphere, 2019
Invasive species can alter ecosystem properties and cause state shifts in landscapes. Resource managers charged with maintaining landscapes require tools to understand implications of alternative actions (or inactions) on landscape structure and function.

Forage Biomass and Chemical Composition of Buffelgrass Genotypes in the Semi‐Arid Region of Brazil

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Forage improvement in semi‐arid regions requires the identification of genotypes capable of maintaining productivity under climatic variability and chronic water scarcity. This study evaluated six buffelgrass (Cenchrus ciliaris L.) genotypes over two production years in northern Minas Gerais, Brazil, to characterize their agronomic, morphological, and ...

Land tenure contributions to protected area growth under alternative conservation targets in the Australian monsoon tropics

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Global Perspective and the Current Characterization of Buffelgrass (Pennisetum ciliare (L.) Link) with Emphasis on Arid Mexican Territories

open access: yesGrasses
Characterized as one of the most controversial and widely used grasses in various regions, buffelgrass (Pennisetum ciliare (L.) Link) is considered a significant and problematic invasive exotic species and an adaptable and resilient forage source with ...

Exotic grass invasion and wildlife abundance and diversity, South‐Central United States

open access: yesWildlife Society Bulletin, 2013
Exotic grasses dominate rangelands in parts of the South‐central United States. We reviewed the literature on the effects of exotic grasses on wildlife functional groups and species, and examined the state of the art of managing exotic vegetation in the ...
