Age-specific, population-level pedigree of wild black bears provides insights into reproduction, paternity, and maternal effects on offspring apparent survival. [PDF]

Ecol Evol, 2022
We installed video cameras at hair stations and combined genetic and video data to reconstruct an age‐specific, population‐level pedigree of wild black bears during 2010–2020. Combining individual birth year with mother‐offpsring relatedness, we also estimated reproductive parameters and evaluated the effect of maternal identity on offspring survival ...

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

Agrosystems, Geosciences & Environment
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.

Conciliating Traditional Green Manure Technique and Modern Precision Agriculture

Proceedings, 2020
Currently the productivity of some European cropping systems is maintained artificially by increasing production factors like mineral fertilizers or pesticides in order to mask the loss of productivity resulting from soil quality degradation.

Forage mass and nutritional value of elephant grass intercropped with forage legumes1

Revista Ceres, 2021
Forage-legume systems are a sustainable and competitive alternative for improving pasture yield and quality because of the symbiotic nitrogen fixation capacity and high nutritional value of legumes.

Agro-ecological services delivered by legume cover crops grown in succession with grain corn crops in the Mediterranean region

Open Agriculture, 2021
Grain corn is the main cereal produced in Portugal. It is grown in intensive monoculture cropping systems that may have negative effects on soil quality, affecting long-term fertility and productivity, and, therefore, the sustainability of the production.

Effect of different botanically‐diverse diets on the fatty acid profile, tocopherol content and oxidative stability of beef

Journal of the Science of Food and Agriculture, Volume 103, Issue 10, Page 4983-4992, 15 August 2023., 2023
Abstract BACKGROUND Beef from pasture‐fed animals is viewed as a healthier and more welfare‐friendly alternative to concentrate‐fed beef. Botanically‐diverse pastures consisting of numerous plant species may alter the fatty acid (FA) profile and the tocopherol content of beef, as well as the oxidative stability of the meat. In the present study, steers

Vegetation dynamics in nitrogen‐fertilized versus mixed legume‐smooth bromegrass pastures interseeded with sorghum‐sudangrass

Agronomy Journal, Volume 115, Issue 2, Page 674-686, March/April 2023., 2023
Abstract Interseeding annual warm‐season grasses may increase forage and pasture productivity. From 2017 to 2019, we conducted a grazing experiment that examined smooth bromegrass (Bromus inermis Leyss.) pasture responses to interseeding sorghum‐sudangrass [Sorghum bicolor (L.) Moench × S. bicolor (L.) Moench ssp.

Improving bermudagrass in the Southeastern United States with alfalfa as an alternative nitrogen source in grazing systems

Grassland Research, Volume 1, Issue 4, Page 280-289, December 2022., 2022
Alfalfa‐bermudagrass mixture under rotational grazing in Tifton, GA 2018. Abstract Background Bermudagrass (Cynodon spp.) is one of the most common perennial warm‐season forages grown in the Southeastern United States. The incorporation of alfalfa (Medicago sativa) into bermudagrass pastures could serve as an alternative source of nitrogen (N) while ...
