Hummingbirds and the plants they visit in the Tehuacán-Cuicatlán Biosphere Reserve, Mexico

open access: yesRevista Mexicana de Biodiversidad, 2011
We describe the relative abundance, plant species visited, and plant communities used by hummingbird species inhabiting the Tehuacán-Cuicatlán Biosphere Reserve, a semiarid area in South-central Mexico.

Effects of the Fungal Endophyte Epichloë festucae var. lolii on Growth and Physiological Responses of Perennial Ryegrass cv. Fairway to Combined Drought and Pathogen Stresses

open access: yesMicroorganisms, 2020
Perennial ryegrass (Lolium perenne) is widely cultivated around the world for turf and forage. However, the plant is highly susceptible to disease and is sensitive to drought.

Evaluation of maize and hemp cultivars as bioenergy crop [PDF]

open access: yes, 2010
We are cultivating annual and perennial crops as monoculture and as mixed culture to investigate plant biomass use for production of renewable energy sources in northern latitudes. We have grown different hemp (Cannabis sativa L.) and bioenergy maize (

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.

Genome-Wide Association Analysis Uncovers Genes Associated with Resistance to Head Smut Pathotype 5 in Senegalese Sorghum Accessions

open access: yesPlants
A newly documented pathotype 5 of the soil-borne fungus Sporisorium reilianum, causing head smut in sorghum, was tested against 153 unexplored Senegalese sorghum accessions. Among the 153 sorghum accessions tested, 63 (41%) exhibited complete resistance,

Functional mapping of seasonal transition in perennial plants [PDF]

open access: yesBriefings in Bioinformatics, 2014
Unlike annuals, all perennial plants undergo seasonal transitions during ontogeny. As an adaptive response to seasonal changes in climate, the seasonal pattern of growth is likely to be under genetic control, although its underlying genetic basis remains unknown. Here, we develop a computational model that can map specific quantitative trait loci (QTLs)

Allelopathic effects of Rumex obtusifolius leaf extracts against native grassland species [PDF]

open access: yes, 2006
In perennial grasslands R. obtusifolius (broad-leaved dock) is often surrounded by certain plant species. Thus, it is hypothesized for the current study that Rumex can affect their neighbouring plant species by allelopathic interactions.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

A Review of Modeled Water Use Efficiency of Highly Productive Perennial Grasses Useful for Bioenergy

open access: yesAgronomy, 2020
Whole plant productivity is obviously the ultimate product of leaf photosynthesis and this has led to numerous efforts to relate the two. However, often with perennial grasses, plant productivity is more sink-limited than source-limited, causing the ...
