Phylogenetic lineages and the role of hybridization as driving force of evolution in grass supertribe Poodae

open access: yesTAXON, Volume 69, Issue 2, Page 234-277, April 2020., 2020
Abstract To investigate the evolutionary diversification and morphological evolution of grass supertribe Poodae (subfam. Pooideae, Poaceae) we conducted a comprehensive molecular phylogenetic analysis including representatives from most of its accepted genera.

Plate meter calibrations for forage mass follow a continuum of sward basal density

open access: yesCrop, Forage &Turfgrass Management, Volume 6, Issue 1, 2020., 2020
Abstract The ability to quantify forage mass (FM) is needed when budgeting pasture supply. Calibrated sward height is an indirect measure of FM. In a previous study, it was observed that the regression intercept and slope of forage density vs. height (FDint and FDslope, respectively) had a strong linear relation, giving rise to the hypothesis that ...

Balance de nitrógeno en pastura de gramíneas y pastura de gramínea más Lotus uliginosus en la sabana de Bogotá, Colombia

open access: yesCiencia y Tecnología Agropecuaria, 2009
En esta investigación se determinó el balance de nitrógeno en dos tipos de pasturas de clima frío: una pastura mixta de dos gramíneas -kikuyo (Pennisetum clandestinum) y festuca alta (Festuca arundinacea)- y pastura asociada de la gramínea festuca alta ...

Sod strength and rhizome characteristics of rhizomatous tall fescue

open access: yesCrop Science, Volume 65, Issue 6, November/December 2025.
Abstract Tall fescue (TF) [Schedonorus arundinaceus (Schreb.) Dumort.] continues to increase in popularity in the northern and transitional climatic zone of the United States because of its superior heat and drought tolerance compared to Kentucky bluegrass (KB) (Poa pratensis L.). However, most turf‐type TF cultivars have a bunch‐type growth habit that

Calibration of Pasture Forage Mass to Plate Meter Compressed Height Is a Second‐Order Response with a Zero Intercept

open access: yesCrop, Forage &Turfgrass Management, Volume 3, Issue 1, Page 1-3, December 2017., 2017
Core Ideas Forage density has a linear relation to pasture height. The regression of forage density to pasture height is a measure of plant morphology within the sward. Forage mass is the product of forage density and pasture height resulting in a second‐order relation with zero intercept. The form of the second‐order relation of forage mass to pasture

Comparison of helicopter and ground surveys for North American elk Cervus elaphus and mule deer Odocoileus hemionus population composition

open access: yesWildlife Biology, Volume 9, Issue 3, Page 199-205, September 2003., 2003
Both ground and helicopter surveys are commonly used to collect sex and age composition data for ungulates. Little attention has been paid, however, to whether data collected by each technique are similar. We compared helicopter and ground composition data for both elk Cervus elaphus and mule deer Odocoileus hemionus across a variety of habitats in the

Complex environmental control of growth in a dominant Mediterranean‐alpine shrub species

open access: yesJournal of Ecology, Volume 112, Issue 7, Page 1516-1532, July 2024.
These findings improve the understanding of the species' ecological niche and show that preceding photosynthetic activity helps Cytisus galianoi to perform even under unfavourable conditions in winter and during the active growth phase. Abstract Mediterranean‐alpine plants are exposed to harsh conditions, forcing them to perform with well‐adapted ...
