Effects of soil physical properties on dung beetle assemblages in pasture landscapes of the Brazilian Cerrado

Agricultural and Forest Entomology, EarlyView.
We assessed the effect of the type of soil texture (loamy sand and sandy loam) and its physical properties on dung beetle species assemblages in a pastureland region of the Brazilian Cerrado. We found a reduction in the total and paracoprid beetle abundances in loamy sand soil. Furthermore, the increase of soil compaction negatively affected the entire

Molecular dating of phylogenetic divergence between Urochloa species based on complete chloroplast genomes

BMC Genomics, 2017
Background Forage species of Urochloa are planted in millions of hectares of tropical and subtropical pastures in South America. Most of the planted area is covered with four species (U. ruziziensis, U. brizantha, U. decumbens and U.

Diazotrophs Show Signs of Restoration in Amazon Rain Forest Soils with Ecosystem Rehabilitation. [PDF]

, 2020
Biological nitrogen fixation can be an important source of nitrogen in tropical forests that serve as a major CO2 sink. Extensive deforestation of the Amazon is known to influence microbial communities and the biogeochemical cycles they mediate. However,

What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle

Entomologia Experimentalis et Applicata, EarlyView.
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...

Leaf anatomy of Urochloa brizantha and Urochloa ruziziensis (Poaceae) plants subjected to different fertilization management practices

Agronomy Science and Biotechnology, 2022
Brazilian agribusiness is heavily influenced by beef export. Thus, it is important to evaluate the quality and growth rate of forage species used as cattle food. Given that the structural organization of leaf cells and tissues is directly related to forage-plant growth, we aimed to analyze the foliar anatomy of Urochloa brizantha and U.

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, EarlyView.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

SHORT-TERM DYNAMIC OF SOIL FERTILITY FROM INTEGRATED CROP-LIVESTOCK SYSTEMS IN TROPICAL SAVANNA

Tropical and Subtropical Agroecosystems, 2017
The chemical attributes and the total organic carbon stock of the soil, from crop-livestock integration systems for renovation of degraded pasture, with fodder sorghum, were evaluated in torpical Savanna.

Wildland Weeds: Paragrass, Urochloa mutica

EDIS, 2013
Paragrass (also referred to as Californiagrass) is thought to have been introduced into Florida sometime in the late 1870s as a forage plant. The semiaquatic grass is a native of tropical Africa, and today it is established in both hemispheres in tropical and subtropical regions as a highly palatable fodder.
