Forage production in mixed grazing systems of elephant grass with arrowleaf clover or forage peanut

Revista Ceres, 2018
Most dairy production systems are pasture-based, usually consisting of sole grass species. This system facilitates pasture management, but results in high production costs, mainly because of nitrogen fertilizers.

Integrating video and genetic data to estimate annual age‐structured apparent survival of American black bears

Population Ecology, Volume 64, Issue 4, Page 300-322, October 2022., 2022
We integrated noninvasive video data with genetic data from hair snares to estimate annual age‐structured apparent survival of American black bears (Ursus americanus), a species with relatively indistinct traits. By combining video and genetic data, we were able to estimate identification accuracy and determine individual age class, which yielded ...

Alteration of plant species mixtures by virus infection: Managed pastures the forgotten dimension

Plant Pathology, Volume 71, Issue 6, Page 1255-1281, August 2022., 2022
This review seeks to highlight the major contribution made by past studies in managed pasture towards understanding the impacts of virus infection on the species balance in mixed plant species systems. Abstract What occurs when virus infection is spreading within a mixed plant species population?

Effect of intercropping wheat with forage legumes on wheat production and ground cover Efeito do consórcio entre trigo e leguminosas forrageiras na produção de trigo e na cobertura de solo

Pesquisa Agropecuária Brasileira, 2001
The use of winter legumes in southern Brazil is hindered by the slow growth of these species during establishment exposing soil surface to erosion. Introduction of these species along with spring wheat (Triticum aestivum L.) was studied as a means of ...
