RESUMO

The Western honey bee Apis mellifera is a managed species that provides diverse hive products and contributing to wild plant pollination, as well as being a critical component of crop pollination systems worldwide. High mortality rates have been reported in different continents attributed to different factors, including pesticides, pests, diseases, and lack of floral resources. Furthermore, climate change has been identified as a potential driver negatively impacting pollinators, but it is still unclear how it could affect honey bee populations. In this context, we carried out a systematic review to synthesize the effects of climate change on honey bees and beekeeping activities. A total of 90 articles were identified, providing insight into potential impacts (negative, neutral, and positive) on honey bees and beekeeping. Interest in climate change's impact on honey bees has increased in the last decade, with studies mainly focusing on honey bee individuals, using empirical and experimental approaches, and performed at short-spatial (<10 km) and temporal (<5 years) scales. Moreover, environmental analyses were mainly based on short-term data (weather) and concentrated on only a few countries. Environmental variables such as temperature, precipitation, and wind were widely studied and had generalized negative effects on different biological and ecological aspects of honey bees. Food reserves, plant-pollinator networks, mortality, gene expression, and metabolism were negatively impacted. Knowledge gaps included a lack of studies at the apiary and beekeeper level, a limited number of predictive and perception studies, poor representation of large-spatial and mid-term scales, a lack of climate analysis, and a poor understanding of the potential impacts of pests and diseases. Finally, climate change's impacts on global beekeeping are still an emergent issue. This is mainly due to their diverse effects on honey bees and the potential necessity of implementing adaptation measures to sustain this activity under complex environmental scenarios.


La abeja occidental Apis mellifera es una especie manejada que proporciona diversos productos de la colmena y servicios de polinización, los cuales son cruciales para plantas silvestres y cultivos en todo el mundo. En distintos continentes se han registrado altas tasas de mortalidad, las cuales son atribuidas a diversos factores, como el uso de pesticidas, plagas, enfermedades y falta de recursos florales. Además, el cambio climático ha sido identificado como un potencial factor que afecta negativamente a los polinizadores, pero aún no está claro cómo podría afectar a las poblaciones de abejas melíferas. En este contexto, realizamos una revisión sistemática de la literatura disponible para sintetizar los efectos del cambio climático en las abejas melíferas y las actividades apícolas. En total, se identificaron 90 artículos que proporcionaron información sobre los posibles efectos (negativos, neutros y positivos) en las abejas melíferas y la apicultura. El interés por el impacto del cambio climático en las abejas melíferas ha aumentado en la última década, con estudios centrados principalmente en individuos de abejas melíferas, utilizando enfoques empíricos y experimentales y realizados a escalas espaciales (<10 km) y temporales (<5 años) cortas. Además, los análisis ambientales fueron basaron principalmente en datos a corto plazo (meteorológicos) y se concentraron sólo en algunos países. Variables ambientales como la temperatura, las precipitaciones y el viento fueron ampliamente estudiadas y tuvieron efectos negativos generalizados sobre distintos aspectos biológicos y ecológicos de las abejas melíferas. Además, las reservas alimenticias, las interacciones planta-polinizador, la mortalidad, la expresión génica y el metabolismo se vieron afectados negativamente. Entre los vacios de conocimiento cabe mencionar la falta de estudios a nivel de colmenar y apicultor, la escasez de estudios de predicción y percepción, la escasa representación de las grandes escalas espaciales y a mediano plazo, el déficit de análisis climáticos y la escasa comprensión de los impactos potenciales de plagas y enfermedades. Por último, las repercusiones del cambio climático en la apicultura mundial siguen siendo un tema emergente, que debe estudiarse en los distintos países. Esto se debe principalmente a sus diversos efectos sobre las abejas melíferas y a la necesidad potencial de aplicar medidas de adaptación para mantener esta actividad crucial en escenarios medioambientales complejos.

RESUMO

RESUMO: Transtorno do Déficit de Atenção com Hiperatividade (TDAH) é um transtorno do neurodesenvolvimento caracterizado por níveis prejudiciais de desatenção e/ou hiperatividade-impulsividade. Foram investigados resultados obtidos em pesquisas sobre impactos do TDAH ao adolescente e foi utilizada a recomendação PRISMA 2020. As bases de dados consultadas foram: APA PsycNet, Lilacs, Medline, PubMed Central, Scorpus, SciELO, a partir dos seguintes descritores: Transtorno do Déficit de Atenção e Hiperatividade, TDAH, Attention Deficit Hyperactivity Disorder, ADHD e Adolescente, Adolescentes, Adolescência, Adolescent, Teenager e Adolescence. Os critérios de inclusão foram: artigos publicados em periódicos entre janeiro de 2001 e janeiro de 2021, em português e inglês, completos e disponíveis online, estudos empíricos, revisados por pares, terem adolescentes como participantes e apresentarem no título, resumo ou corpo do texto os descritores referidos. Os dados foram tratados e organizados conforme check list (recomendação PRISMA 2020). Análises estatísticas descritivas foram realizadas com o Excel 2019. Para apresentar os resultados, utilizaram-se o fluxograma PRISMA, quadro e figuras. Incluíram-se 68 artigos que apontaram variedade de impactos negativos ao desenvolvimento do adolescente nas áreas sociais/relacionais, comportamentais, biológicas, neurológicas, cognitivas, psicológicas e psicopatológicas. Possível limitação desta revisão pode ser a não inclusão de artigos em outros idiomas, além do inglês e português. Os resultados sugerem multidimensionalidade dos impactos do TDAH ao adolescente, requerendo abordagem pluridimensional para evitar cronicidade, reduzindo seus efeitos ao desenvolvimento.


ABSTRACT: Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by harmful levels of inattention and/or hyperactivity-impulsivity. Results obtained from research on the impact of ADHD on adolescents were investigated and the PRISMA 2020 recommendation was used. The databases consulted: were APA PsycNet, Lilacs, Medline, PubMed Central, Scorpus, SciELO, from the following descriptors: Transtorno do Déficit de Atenção e Hiperatividade, TDAH, Attention Deficit Hyperactivity Disorder, ADHD and Adolescente, Adolescentes, Adolescência, Adolescent, Teenager and Adolescence. The inclusion criteria were: articles published in journals between January 2001 and January 2021, in Portuguese and English, complete and available online, empirical studies, peer reviewed, with adolescents as participants and presenting in the title, abstract or body of the text the referred descriptors. The data were processed and organized according to the check list (PRISMA 2020 recommendation). Descriptive statistical analyzes were performed using Excel 2019. The PRISMA flowchart, table and figures were used to present the results. Sixty-eight articles were included that pointed to a variety of negative impacts on adolescent development in the social/relational, behavioral, biological, neurological, cognitive, psychological and psychopathological areas. A possible limitation of this review may be the non-inclusion of articles in languages other than English and Portuguese. The results suggest the multidimensionality of the impacts of ADHD on adolescents, requiring a multidimensional approach to avoid chronicity, reducing its effects on development.

RESUMO

Microplastics (Mps) pose a significant environmental challenge with global implications. To examine the effect of Mps on coastal and oceanic surface waters, as well as in marine organisms, 167 original research papers published between January 2013 and September 2022 were analyzed. The study revealed an unequal distribution of research efforts across the world. Fragments and fibers were the most frequently detected particles in ocean surface waters and marine biota, which mainly consisted of colored and transparent microparticles. Sampling of Mps was primarily done using collecting nets with a mesh size of 330 µm. Most articles used a stereomicroscope and Fourier-Transform Infrared spectroscopy for identification and composition determination, respectively. Polyethylene and polypropylene were the most frequent polymers found, both in coastal waters and in marine organisms. The major impact observed on marine organisms was a reduction in growth rate, an increase in mortality, and reduced food consumption. The hydrophobic nature of plastics encourages the formation of biofilms called the "plastisphere," which can carry pollutants that are often toxic and can enter the food chain. To better define management measures, it is necessary to standardize investigations that assess Mp pollution, considering not only the geomorphological and oceanographic features of each region but also the urban and industrial occupation of the studied marine environments.

RESUMO

The ingestion of plastic marine litter (PML) by sea turtles is widespread and concerning, and the five species that occur in the southwestern Atlantic - green, loggerhead, olive ridley, leatherback and hawksbill - are vulnerable to this pollution. Here, we quantified and characterized PML ingested by these species in southern Brazil, and observed PML ingestion in 49 of 86 sampled individuals (~57.0%). Green turtles presented the highest rates and variety of ingested plastics, and such ingestion has been high at least since 1997. Omnivorous turtles presented higher PML ingestion than carnivorous ones. Loggerheads displayed a negative correlation between body size and number of ingested items. Green turtles ingested mostly flexible transparent and flexible/hard white plastics; loggerheads ate mainly flexible, hard and foam fragments, in white and black/brown colors. These results help us better understand PML ingestion by sea turtles, highlighting the seriousness of this threat and providing information for prevention and mitigation strategies.
