Diverged Subpopulations in Tropical Urochloa (Brachiaria) Forage Species Indicate a Role for Facultative Apomixis and Varying Ploidy in Their Population Structure and Evolution [PDF]

Annals of Botany, 2022
Background Urochloa (syn. Brachiaria) is a genus of tropical grasses sown as forage feedstock, particularly in marginal soils. Here we aimed to clarify the genetic diversity and population structure in Urochloa species to understand better how population

Meiotic behavior in apomictic Brachiaria ruziziensis × B. brizantha (Poaceae) progenies [PDF]

Scientia Agricola, 2012
Hybrids combining desirable traits from divergent parents are the main objective of some Brachiaria (Syn. Urochloa P. Beauv.) breeding programs. There is great interest in the development of apomictic hybrid cultivars that combine desirable genes such as

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region. [PDF]

Pest Manag Sci
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

Molecular and Structural Characterization of Foam Proteins from Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) Nymphs Reveals Adaptive Features and Potential Targets for Pest Control. [PDF]

Arch Insect Biochem Physiol
Nymphs of Mahanarva spectabilis produce a protective foam that supports survival, reduces plant damage, and contributes to adult population establishment. Proteomic profiling combined with protein sequencing and structural modeling revealed foam proteins enriched in functional domains associated with environmental resilience.

How does the condition of the pasture in late winter influence the plant and animal responses in the subsequent seasons?

Bioscience Journal, 2022
This study aimed to test the hypotheses: (i) the deferred pasture with lower height in late winter has greater herbage accumulation rate (HAR) and better structure, which facilitates the animal selective grazing during the subsequent spring and summer ...

Does amount of cut vegetal residue on the canopy influence growth and the structural characteristics of marandu palisadegrass?

Bioscience Journal, 2022
The pasture mowing in late winter removes the old forage, improving the pasture structure in spring and summer. However, the residue after mowing can affect tillering, thus limiting forage production and the structural characteristics of pasture.

The sward height at the early stockpiling period modifies the structural characteristics of marandu palisadegrass under continuous stocking

Bioscience Journal, 2022
The control of sward height at the early stockpiling period influences the structural characteristics of stockpiled sward in winter. So, we conducted this work on the Cerrado region of Brazil based on the hypothesis that the reduction of pasture height ...

Tillering dynamics in spring and summer of marandu palisade grass pastures previously used under deferred grazing

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2021
This work was conducted to evaluate the effect of deferred pasture condition of Brachiaria brizantha cv. Marandu in the late winter on tillering during the growing season.
