Deforestation is the turning point for the spreading of a weedy epiphyte: an IBM approach
Chaves, Cleber Juliano Neves; Leal, Bárbara Simões Santos ; Rossatto, Davi Rodrigo ; ; (Scientific Reports, 2021) [Artigo]
The rapid spread of many weeds into intensely disturbed landscapes is boosted by clonal growth and self-fertilization strategies, which conversely increases the genetic structure of populations. Here, we use empirical and ... -
Beneficial Effect of Silicon Applied Through Fertigation Attenuates Damage Caused by Water Deficit in Sugarcane
Teixeira, Gelza Carliane Marques; Mello Prado, Renato de ; Rocha, Antonio Márcio Souza ; Silveira Sousa Junior, Gilmar da ; Gratão, Priscila Lupino (Journal of Plant Growth Regulation, 2021) [Artigo]
Water deficit limits the establishment of sugarcane that uses Pre-sprouted seedlings (PSS). Silicon (Si) can mitigate the effects of water deficiency, but it is not known if the Si applied through fertigation is efficient ... -
Do neighbours matter? The effect of single- and mixed-species sowing density on seed germination of annual wetland plants
Bao, Francielli; Rossatto, Davi Rodrigo ; ; ; de Assis, Marco Antonio ; ; Ramos, Desirée Marques (Applied Vegetation Science, 2021) [Artigo]
Question: Germination is one of the decisive processes influencing species presence and plant community structure. Here, we investigated the influence of seed density and single and mixed species on germination percentage ... -
Sub-lethal effects of a Bt-based bioinsecticide on the biological conditioning of Anticarsia gemmatalis

Bioinsecticides based on Bacillus thuringiensis (Bt) Berliner, 1915 are widely used to control lepidopteran in several crops. However, surviving insects exposed to the sub-lethal concentration of Bt-based bioinsecticides ... -
Bottom-up effects of breeding tomato genotypes on behavioural responses and performance of Tetranychus evansi population
Savi, Patrice Jacob; ; Carvalho, Rogério Falleiros ; de Andrade, Daniel Júnior (Journal of Pest Science, 2021) [Artigo]
The tomato red spider mite, TRSM, Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae), is an invasive tomato pest in several countries, with potential to reduce yield by up to 90% in Africa. Solanum habrochaites, ... -
Cryptochrome 1a of tomato modulates nutritional deficiency responses
D'Amico-Damião, Victor; ; Garcia, Luis Felipe de Oliveira ; ; Prado, Renato de Mello ; Carvalho, Rogério Falleiros (Scientia Horticulturae, 2022) [Artigo]
The blue light photoreceptor cryptochromes are involved in nutritional response pathways in plants. Evidence shows that cryptochromes mediate the control of genes related to nutrients accumulation in plants. However, nothing ... -
Giant Anteater Population Density Estimation and Viability Analysis Through Motion-Sensitive Camera Records
; Bianchi, Rita de Cassia; (Journal of Wildlife Management, 2021) [Artigo]
Giant anteater (Myrmecophaga tridactyla) populations are decreasing throughout their range. We tested a methodology for individual identification using camera records and fur patterns to estimate the giant anteater population ... -
Water deprivation induces biochemical changes without reduction in the insecticidal activity of maize and soybean transgenic plants
Silva, Juliana Barroso; Mori, Raphael ; ; ; ; ; ; Gratão, Priscila Lupino ; Rossi, Guilherme Duarte (Journal of Economic Entomology, 2021) [Artigo]
Like conventional crops, transgenic plants expressing insecticidal toxins from Bacillus thuringiensis (Bt) are subjected to water deprivation. However, the effects of water deprivation over the insecticidal activity of Bt ... -
