Short‐term effects of grass–legume mixtures on greenhouse gas fluxes in southeastern US cool‐season annual forage systems

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract The agricultural sector contributes to the greenhouse gas (GHG) fluxes in the United States. In livestock systems, grass–legume mixtures provide agronomic benefits, but their role in GHG mitigation remains understudied. This study evaluated the short‐term effects of two forage treatments on nitrous oxide (N2O), methane (CH4), and carbon ...

Joint telemetry and mark–recapture model reveal resource selection affects Northern Bobwhite chick survival

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Resource selection studies have become increasingly common since the advent of modern animal tracking equipment, yet most studies fail to examine how selection affects vital rates or population growth (i.e., fitness). Without investigating if optimal habitat selection is facilitated in a system, conservation efforts may promote ineffective ...

Zastosowanie metody RAPD w poszukiwaniu markerów gatunkowych oraz w badaniu polimorfizmu u Lolium perenne L., Lolium multiflorum Lam. [PDF]

, 1997
Zastosowanie metody RAPD pozwoliło na wytypowanie fragmentów DNA pretendujących do miana markerów gatunkowych oraz na dokonanie opisu zmienności genetycznej u dwóch gatunków traw z rodzaju Lolium. Do poszukiwania markerów gatunkowych u Lolium perenne i L.

Identification of quantitative trait loci for seed traits and floral morphology in a field-grown Lolium perenne × Lolium multiflorum mapping population

, 2010
Lolium perenne L. (perennial ryegrass), and Lolium multiflorum Lam. (annual or Italian ryegrass), differ in several traits related to seed yield. Generally, L. multiflorum spikes are larger than L.

Genetic relationships within and among Iberian fescues (Festuca L.) based on PCR-amplified markers [PDF]

, 2006
The genus Festuca comprises approximately 450 species and is widely distributed around the world. The Iberian Penninsula, with more than 100 taxa colonizing very diverse habitats, is one of its main centers of diversification. This study was conducted to
