Sistematics, Biogeography and Natural History of butterflies in the subtribe Phyciodina (Nymphalidae: Nymphalinae: Melitaeini)

Eduardo Barbosa
The Neotropical region, considered one of the regions with the greatest biodiversity on the planet, is especially important for the butterfly fauna. Among the species that occur in the Neotropical region, there are those that belong to the tribe Melitaeini, a group with approximately 250 species, of which 120 are exclusive to the Neotropical region, and were divided into five distinct clades according to phylogenetic studies published in the first decade of the 2000’s. One...

Modelling conventional and tall transmission towers directly in time domain for electromagnetic transient analysis

Anderson Ricardo Justo De Araújo
This project is a continuation of the doctorate (FAPESP grant 2014/18551), in which a methodology was developed to model transmission towers directly in the time domain taking into
account the tower-footing grounding system, real soils, and tower structure. Such parameters are
generally omitted in traditional transmission tower modeling. Additionally, tall towers were studied in which no proper model was proposed in the scientific literature. It was found that the
models for traditional transmission towers are not suitable for...

Abandoned pastures and restored savannahs have distinct patterns of plant-soil feedback and nutrient cycling compared with native Brazilian savannahs.

André D'Angioli, André Giles, Patrícia Costa, Gabriel Wolfsdorf, Luísa Pecoral, Larissa Verona, Fernanda Piccolo, Alexandre Sampaio, Isabel Schmidt, Lucy Rowland, Hans Lambers, Ellen Kandeler, Rafael Oliveira & Anna Abrahão
Around 40% of the original Brazilian savannah territory is occupied by pastures dominated by fast-growing exotic C4 grasses, which impact ecosystem nutrient cycling. The restoration of these areas depends on the re-establishment of soil processes. We assessed how restoration of abandoned pastures through direct seeding of native species and land-management practices (burning and ploughing) affect soil nutrient cycling dynamics compared to native savannahs. We compared the activity of soil enzymes related to carbon (C), nitrogen...

Climate variability and aridity modulate the role of leaf shelters for arthropods: a global experiment

Gustavo Q Romero
Current climate change is disrupting biotic interactions and eroding biodiversity worldwide. However, species sensitive to aridity, high temperatures and climate variability might find shelter in microclimatic refuges, such as leaf rolls built by arthropods. To explore how the importance of leaf shelters for terrestrial arthropods changes with latitude, elevation, and climate, we conducted a distributed experiment comparing arthropods in leaf rolls vs. control leaves across 52 sites along an 11,790 km latitudinal gradient. We then...

Crotalaria pallida chemical defence and ant attendance

Martin Pareja & Luiz Rezende
The efficiency of different plant defences is expected to vary depending on the combination and abundance of herbivores. Effectiveness of ant-mediated defences can also depend on ant activity and local ant assemblage, which can vary due to human activities such as intensive grazing. We used the plant Crotalaria pallida (Fabaceae), its two pod-boring herbivores and the ants that visit the extrafloral nectaries (EFNs) to understand how chemical defence and ant-plant associations affect plant damage. We...

Trophic allometry in a predator that carries corpses of its prey

Nicole Victor & Raul Costa-Pereira
Ant-snatching assassin bugs carry a ‘backpack’ of ant corpses as an antipredator strategy. From photographs, we quantified the relative size and number of ants in these backpacks. We found a trade-off between size and number of carried ants, suggesting that trophic allometry has implications beyond energy acquisition, potentially affecting camouflage.

Plantando floresta no coração da monocultura canavieira: uma etnografia sobre as práticas agroecológicas e agroflorestais em assentamentos da reforma agrária na região de Ribeirão Preto

Carlos Alberto Corrêa Moro
A região de Ribeirão Preto é conhecida nacionalmente como um polo econômico do agronegócio, sobretudo pela magnitude da agroindústria sucroalcooleira que rendeu à cidade o slogan de “Capital do Agronegócio”. O crescimento de Ribeirão Preto se dá na esteira de uma conjunção de fatores diversos e trágicos (SILVA, 1999): migração de mineiros expulsos pelo declínio da atividade de mineração em grande escala no estado de Minas Gerais em meados do século XVIII; a expansão da...

Filogenômica e macroecologia em Orchidaceae: integrando a citogenética e a ecologia no estudo da evolução de orquídeas neotropicais

Ana Moraes
A existência de associações entre os caracteres citogenéticos, em especial a ploidia, e as características ecológicas, como a colonização de ambientes extremos, foi inicialmente proposta a quase um século, mas ainda hoje são poucos os estudos que avaliam se tais associações representam tendências gerais em plantas ou são resultados de casos pontuais. Tais análises macroecológicas, integrando dados citogenéticos e ecológicos, dependem obrigatoriamente de um background evolutivo que só pode ser oferecido por hipóteses filogenéticas robustas,...

Nuñez-Rosas, María Del Coro Arizmendi, Carsten Rahbek & Bo Dalsgaard
Research on resource partitioning in plant-pollinator mutualistic systems is mainly concentrated at the levels of species and communities, whereas differences between males and females are typically ignored. Nevertheless, pollinators often show large sexual differences in behaviour and morphology, which may lead to sex-specific patterns of resource use with the potential to differentially affect plant reproduction and diversification. We investigated variation in behavioural and morphological traits between sexes of hummingbird species as potential mechanisms underlying sex-specific...

Extrato da casca de jabuticaba (Myrciaria jaboticaba) como terapia adjuvante à ablação androgênica no câncer de próstata resistente à castração: estudo da apoptose, dos mecanismos de neovascularização tumoral e de novos biomarcadores

Fabio Montico
Prostate cancer (PCa) is the second most common cancer in men and its progression requires the development of a new vascular network to supply oxygen and nutrients to the tumor. This phenomenon can occur from preexisting vessels, thus defining angiogenesis, or through vessel-independent mechanisms, such as vasculogenic mimicry (VM), which has been registered mainly in aggressive and metastatic tumors. In the prostate, the standard protocol for treating advanced tumor stages is androgen deprivation therapy (ADT)...

Phytogeographic origin determines Tropical Montane Cloud Forest hydraulic trait composition

Fernanda De Vasconcellos Barros, Fernanda Barros, Paulo Bittencourt, Cleiton Eller, Caroline Signori-Müller, Leonardo Meireles & Rafael Oliveira
Tropical montane cloud forests (TMCF) have unique climatic conditions, which allow the coexistence of plant lineages with different phytogeographic origins from tropical versus temperate climates. Future climate projections suggest TMCFs will be subjected to increasing drought stress due to fog uplift and higher temperatures, possibly leading to tree mortality and local extinctions, and consequently changes in forest composition and functioning. Characterising community functional composition, trade-offs among traits and the drivers of community assembly is of...

Genomic, transcriptomic and metagenomic in populations of native stingless bees aiming the search for detoxification genes

Patricia Azevedo
O declínio drástico das abelhas, sejam elas nativas ou exóticas, é uma ameaça iminente aos serviços ecossistêmicos de polinização e, consequentemente, à segurança alimentar mundial e à preservação e conservação dos recursos naturais. Vários fatores têm sido associados a esse declínio, dentre eles o uso de inseticidas merece destaque, visto que o Brasil é o maior consumidor mundial de agrotóxicos. Assim, o presente estudo propõe montar um genoma e transcriptoma da abelha nativa sem ferrão...

Full-wave black-box transmission tower modeling in ATP-software for electromagnetic transient analysis of power systems

Anderson Ricardo Justo De Araújo
BEPE (FAPESP grant 2021/11106-0)-with Prof. Dr. Behzad Kordi from University of Manitoba (UofM), Winnipeg, Canada. The objective of the research internship is to model transmission towers (conventional and tall structures) and to predict the occurrence of backflashovers (BFs) when lightning strikes hit overhead power lines. This model consists of a tower structure, including the tower-footing grounding system buried into a realistic model of soil. Then, the tower structure model is represented by an electric circuit...

Geographical variation in the trait-based assembly patterns of multitrophic invertebrate communities

Diane S. Srivastava, A. Andrew M. MacDonald, Valério D. Pillar, Pavel Kratina, Vanderlei J. Debastiani, Laura Melissa Guzman, M. Kurtis Trzcinski, Olivier Dézerald, Ignacio M. Barberis, Paula M. De Omena, Gustavo Q. Romero, Fabiola Ospina Bautista, Nicholas A. C. Marino, Céline Leroy, Vinicius F. Farjalla, Barbara A. Richardson, Ana Z. Gonçalves, Bruno Corbara, Jana S. Petermann, Michael J. Richardson, Michael C. Melnychuk, Merlijn Jocqué, Jacqueline T. Ngai, Stanislas Talaga, Gustavo C. O. Piccoli … & Régis Céréghino
It has been argued that the mechanisms structuring ecological communities may be more generalizable when based on traits than on species identities. If so, patterns in the assembly of community-level traits along environmental gradients should be similar in different places in the world. Alternatively, geographic change in the species pool and regional variation in climate might result in site-specific relationships between community traits and local environments. These competing hypotheses are particularly untested for animal communities....

A face sociopolítica da crise climática e eventos extremos: estudo com as ecovilas paulistas e bávaras

Luciana Lima
As ecovilas surgiram do movimento social contracultural e antissistema das comunidades alternativas da década de 1970. Essas organizações sociais têm, como propósito, a regeneração humana, social e natural. No entanto, não há dados publicados de como essas comunidades têm incorporado a crise do clima e eventos extremos. A forma como os movimentos sociais lidam com a crise pode influenciar seu poder de resposta e o resultado de sua atuação social e ambiental. A proposta da...

Axell Kou Minowa
A meiofauna é um conjunto operacional de microinvertebrados com importante papel ecológico no bentos e fitofauna de ambientes marinhos e dulcícolas de todo o globo. Entre eles, destaca-se o clado Gastrotricha por sua abundância e diversidade morfológica, representada por 860 espécies, divididas em Macrodasyida e Chaetonotida. Apesar de se passarem dois séculos desde o primeiro quetonótido descrito, devido às dificuldades inerentes do trabalho com animais de tamanho diminuto e frágeis, ainda existem muitas lacunas no...

Data from: Analysis of the PEBP gene family and identification of a novel FLOWERING LOCUS T orthologue in sugarcane

Julien Venail, Paolo Da Silva Santos, Joao Manechini, Leonardo Alves, Maximiliano Scarpari, Thais Falcao, Elisson Romanel, Michael Brito, Renato Vicentini, Luciana Pinto & Stephen Jackson
Sugarcane (Saccharum spp.) is an important economic crop for both sugar and biomass, the yields of which are negatively affected by flowering. The molecular mechanisms controlling flowering in sugarcane are nevertheless poorly understood. RNA-seq data analysis and database searches have enabled a comprehensive description of the PEBP gene family in sugarcane. It is shown to consist of at least 13 FLOWERING LOCUS T (FT)-like genes, two MOTHER OF FT AND TFL (MFT)-like genes, and four...

DELLA protein and the signaling crosstalk in mycorrhizal Eucalyptus species in response to phosphate

Luana Ferreira Torres
Phosphorus (P) is part of essential molecules for life, such as ATP, RNA and DNA molecules, and membrane lipids, among others, without which plants cannot survive. Phosphate rocks used to produce fertilizers are finite and the fact that P in the soil is frequently poorly available to plants makes it necessary to maximize the efficiency of P use by plants. More than 80% of terrestrial plant species can establish mutualistic symbiosis with arbuscular mycorrhizal (AM)...
