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

Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 321-328, April 2026.
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 ...

CONTROLE CULTURAL E QUÍMICO DE Conyza spp. NO CONSÓRCIO DE MILHO COM Urochloa ruziziensis

Revista Brasileira de Herbicidas, 2020
As integrações de métodos de controle, visando o manejo de buva (Conyza spp.) passaram a ser práticas fundamentais nos sistemas integrados de produção, tais como milho (Zea mays) em consórcio com capim-ruziziensis (Urochloa ruziziensis). Os objetivos deste trabalho foram avaliar a eficácia da cobertura do capim-ruziziensis sobre a supressão da buva e ...

Efeito do estresse hídrico na germinação de sementes nuas e incrustadas de cultivares do gênero Urochloa spp

Cadernos Cajuína
As cultivares de Urochloa spp. são amplamente utilizadas na produção de forragem no Brasil. Contudo, seu desenvolvimento é fortemente influenciado por fatores ambientais, especialmente pelo déficit hídrico, um dos principais limitantes da produtividade ...

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

Ecological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
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 ...

Impacts of Intercropping Maize–Grass–Legume for Silage Production and Oversowing Black Oat for Lamb Grazing on Soil Fertility

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Intercropping grasses and legumes could be an important strategy for sustainable food production in tropical weathered soils. This study aimed to assess the impact of intercropping systems comprising maize and grass with or without a legume for silage production and overseeded black oat overseeded for lamb grazing on crop production, root ...

Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...

Crop yield and weed community response to cover crop termination strategies under organic management in the US Mid‐South

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Weed management is still a main drawback for the wider adoption of organic cropping systems in the Mid‐South. Holistic cropping management, which involves a combination of cover cropping, tillage practices, and integrating crop and livestock systems, is an option to overcome this challenge.

Estimating the botanical composition of bahiagrass–rhizoma peanut pastures using aerial multispectral imagery and deep learning

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Estimating the botanical composition in mixed pastures is challenging due to resource‐intensive sampling methods overlooking grassland spatial variability. We aimed to (I) classify bahiagrass (Paspalum notatum Flügge) and rhizoma peanut (Arachis glabrata Benth.) in grass–legume pastures using aerial multispectral imagery and machine learning, (
