1. Seicho-No-Ie, Deep ecology e as particularidades da globalização nipônica: a comida sob a ótica da ética religiosa ambiental
Resumo: O objetivo principal deste artigo é estabelecer uma relação entre Seicho-No-Ie, Deep Ecology e comida. A hipótese gira em torno da seguinte premissa: a relação entre esses três elementos envolve uma discussão centrada na ética religiosa ambiental, que se preocupa com o bem-estar do meio ambiente como um todo. Com base nessa ética, Masanobu

2. Ecology of knowledges and languages in Latin American academic production
Resumo A produção acadêmica latino-americana é analisada em relação à sua visibilidade, internacionalização e ecologia de saberes e de línguas nesse processo. Ferramentas bibliométricas foram utilizadas para formar um corpus de 2.939 estudos da base de dados Scopus entre 2010-2019, analisados em duas dimensões: a dimensão input/editorial, e a di

3. Avaliação da microbiota intestinal em adultos com esofagite erosiva
RESUMO CONTEXTO: A doença do refluxo gastroesofágico (DRGE) é uma das enfermidades mais comuns na prática clínica e possui fisiopatologia multifatorial. Disbiose da microbiota intestinal pode ter influência em mecanismos envolvidos nesta doença, como mudanças nos padrões motores gastrointestinais, elevação da pressão intra-abdominal e aumento d

4. The aquatic species Pontederia azurea and P. crassipes (Pontederiaceae) in the Pantanal, Brazil: evidence of how plant structure can simultaneously reflect phylogeny and ecology
ABSTRACT Hydric fluctuations in the Pantanal comprise annual dry and wet seasons that modify local diversity and plant morphology and anatomy. Widespread in this wetland are the sympatric Pontederia azurea and P. crassipes, which, although primarily aquatic, can also develop in non-flooded environments. This study undertook a comparative investigation of the

5. Advances in the knowledge of the natural history of aquatic plants in the Neotropics
ABSTRACT Until the mid-XX century, little awareness on the ecological services or socio-environmental problems and benefits related to aquatic plants culminated in bottlenecks on their natural history, especially for the Neotropics. In this context, Acta Botanica Brasilica (ABB) organized this special issue to promote the advancement of knowledge on this eco

6. Brazilian herbaria: an overview
ABSTRACT Herbaria represent irreplaceable repositories of biodiversity and are used to answer questions about conservation, ecology, systematics, and other sciences. In this sense, we characterize the infrastructure, human resources, and idiosyncrasies of Brazilian herbaria. To achieve this goal, curators were sent a structured and standardized questionnaire

7. Can plant hybridization and polyploidy lead to pollinator shift?
ABSTRACT Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyploi

8. Pollen sources used by Frieseomelitta Ihering 1912 (Hymenoptera: Apidae: Meliponini) bees along the course of the Rio Negro, Amazonas, Brazil
ABSTRACT Insect pollination has influenced the evolution and diversification of angiosperms. Consequently, knowing plants used as food sources by bees, the most important pollinator group, is the first step toward understanding how their ecological relationships works. Pollen source information is also highly relevant for bee management and associated fruit

9. METABOLÔMICA DE PLANTAS: MÉTODOS E DESAFIOS
Metabolomics has played a central role in various areas of plant sciences, offering new perspectives for the advancement of agriculture, drug discovery, chemical ecology and taxonomy. Plant metabolomics (identification and quantification) aims to understand the relationship between biological systems and genetic, pathological and or environmental stimuli in

10. Flowering and pollination ecology of Cleistocactus baumannii (Cactaceae) in the Brazilian Chaco: pollinator dependence and floral larceny
ABSTRACT Cleistocactus baumannii is the only ornithophilous cactus species in the Brazilian Chaco. In addition, this species of Cactaceae invests heavily in flowering in the ecoregion. Such characteristics motivated us to evaluate the temporal availability of flowers in the context of its floral visitors. The reproductive system of C. baumannii, the number o

11. AUTOMATED INDIVIDUAL TREE DETECTION IN AMAZON TROPICAL FOREST FROM AIRBORNE LASER SCANNING DATA
ABSTRACT Light Detection and Ranging (LiDAR) derived individual tree crown attributes can potentially serve as a tool for ecology and forest dynamics studies and reduce field inventory costs. In this study, four methods of individual tree detection (ITD), Watershed, Silva et al. (2016), Dalponte and Coomes (2016), and Coomes et al. (2017), were evaluated in

12. A HISTÓRIA DE GIGANTE: CONSERVAÇÃO E CAÇA NO PANTANAL
Resumo Este artigo aborda o primeiro estudo de campo científico sobre a ecologia da onça-pintada, realizado no final dos anos 1970, no Pantanal brasileiro. O ponto de partida é um texto escrito por George Schaller, responsável por aquele estudo, no qual podemos acompanhar a história do cão chamado Gigante. Trata-se de um personagem que atravessa fronte
