Resource and non-resource root competition among trees of different successional status [PDF]

, 2009
1. This study assessed the effects of resource (i.e. nutrients) and non-resource (i.e. interference for space) competition from fine roots of competing grasses on the growth, morphology and architecture of fine roots of four tree species of varying ...

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

Integrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Differences in microbiota between two multilocus lineages of the sugarcane Aphid (Melanaphis sacchari) in the continental United States [PDF]

, 2020
The sugarcane aphid (SCA), Melanaphis Sacchari (Zehntner) (Hemiptera: Aphididae), has been considered an invasive pest of sugarcane in the continental United States since 1977. Then, in 2013, SCA abruptly became a serious pest of U.S.

Sugarcane nutrition under organomineral fertilizer, phosphate‐solubilizing bacteria, and reduced phosphate doses

Annals of Applied Biology, EarlyView.
Sugarcane phosphorus (P) availability is limited in tropical soils, requiring strategies to improve fertilizer efficiency. This study evaluated Bacillus velezensis UFV 3918 (Bv) in combination with an organomineral fertilizer (OF) at reduced monoammonium phosphate (MAP) doses. It showed that Bv + OF + 1/3 MAP achieved soil and plant P levels comparable

Calcário e escória de siderurgia avaliados por análise foliar, acúmulo, e exportação de macronutrientes em cana-de-açúcar Lime and slag evaluated by leaf analysis, macronutrient accumulation and export of sugarcane

Scientia Agricola, 2002
A opção de uso de materiais corretivos alternativos como as escórias de siderurgia, pode influenciar na absorção de nutrientes pela planta e, consequentemente, na diagnose foliar, acúmulo e exportação de nutrientes.

Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

Entomologia Experimentalis et Applicata, EarlyView.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Escarificação de um Latossolo Vermelho na pós-colheita de soqueira de cana-de-açúcar Chisel plowing in an Oxisol in post harvest of ratoon cane

Revista Brasileira de Ciência do Solo, 2004
A escarificação nas entrelinhas da soqueira da cana-de-açúcar, associada à adubação e à gradagem (tríplice cultivo), é adotada como um recurso para amenizar o problema da compactação do solo; entretanto, pouco se sabe de seus efeitos no enraizamento da ...
