Occurrence of pests and diseases in cactus pear genotypes / Ocorrência de pragas e doenças em genótipos de palma forrageira

The objective was to evaluate the occurrence of pests, diseases and mortality rate in nine genotypes of cactus pear (Nopalea cochenillifera) destined for forage production. The genotypes were implanted in a complete randomized block design, with nine treatments and three replications. After 330 days of cultivation, the occurrence of pests and diseases and verification of plant mortality were carried out. Among all the pests and diseases observed in this experimental trial, the most prevalent disease regardless of the evaluated genotype was the anthracnose stain “Colletotrichum gloeosporioides” (49.20%) and the less frequent diseases were the resine “Dothiorella ribis” (6.87%) and soft rot “Erwinia carotovora” (2.58%). The only occurrence pest was the cochineal in scales “Diaspis echinocacti” (22.69%). The Texas (V13) and Negro Michoacan (F07) genotypes showed the highest occurrence of pests and diseases, from 50% of the total plants, followed by anthracnose stain and cochineal in scales. On the contrary, the genotypes Tamazunchale (V12) and California (V14) were not affected by any pest or disease. It was observed that the genotypes Nopalea Uruapan (V20) and Blanco San Pedro (V19), had a lower occurrence of pests and diseases, less than 20% of the total plants. The genotypes that presented the highest mortality rate were Texas (V13), Blanco San Pedro (V19) and Polotitlan (V09), with 80, 70 and 65% mortality rate, respectively. The genotypes Nopalea Uruapan (V20) and California (V14) had the lowest mortality rate (20 and 35%), respectively. The genotypes that were least affected by pests and diseases and had the lowest mortality rate are Tamazunchale (V12), California (V14) and Nopalea Uruapan (V20)

O Serviço de documentação textual e iconografia do Museu Paulista

The essay compares the curatorship's works realized during the decade of 1990 by the actual Department of Textual and Iconographical Documentation of Museu Paulista, responsible for the MP Fund / Permanent File (Fundo MP/Arquivo Permanente), hundreds of collections and textual funds and 50.000 iconography pieces, great part of which are gathered in photographic collections. It shows how the documentation work extrapolates the limits of SVDHICO in order to integrate itself with the group activities of the museum and with other research groups. It also points towards new work methodologies which allow to perform the curatorship in an integrated way with the interdisciplinary research and the culture diffusion.O artigo faz um balanço dos trabalhos de curadoria realizados durante a década de 1990 pelo atual Serviço de Documentação Textual e Iconografia do Museu Paulista, responsável pelo Fundo MP/Arquivo Permanente, centenas de coleções e fundos textuais e 50.000 peças de iconografia, grande parte delas reunidas em coleções fotográficas. Mostra como o trabalho de documentação extrapola os limites do SVDHICO para integrar-se com as atividades de conjunto do Museu e com outros grupos de pesquisa. Aponta também para novas metodologias de trabalho com imagens que permitem realizar a curadoria de forma integrada à pesquisa interdisciplinar e à difusão cultural

Avaliação das estratégias de capacitação para o monitoramento da biodiversidade em unidades de conservação

The article evaluates several training strategies implemented since 2013 within the Monitora Program’s training cycle. We analyzed 39 national courses for focal points from 2013 to 2023 and 15 courses from ICMBio’s People Development National Plan, from 2021 to 2023. All this effort culminated on the Monitora Program implemented in 113 federal protected areas (PAs). An average of 26 students and 10 federal PAs participated in each course. The largest number of PAs starting monitoring usually occurred about one year after the first courses. Reaction evaluation results showed improvement in the participants’ performance at work (92%) and in their confidence to apply the knowledge and skills acquired (87%). It is a great challenge to develop courses for different social and economic realities, therefore different strategies are needed to better develop students' knowledge, skills, and competencies. In this sense, the following strategies stand out: the variety of modalities (face-to-face courses, hybrid, online) and the multiple levels covered (local – only one PA or regional/national – several PAs), collective construction from course design to data analysis, and the diversity of pedagogical tools used in the learning process.El objetivo de este estudio de caso es evaluar las estrategias de formación que se han implementado desde 2013 en el ciclo formativo del Programa Monitora. Se analizaron 39 cursos de puntos focales nacionales, de 2013 a 2023, y 15 cursos del Plan Nacional de Desarrollo de las Personas del ICMBio de 2021 a 2023. Con este esfuerzo de capacitación, se logró iniciar la implementación del Programa Monitora en 113 areas protegidas (APs) federales. En cada curso participaron, en promedio, 26 estudiantes y 10 APs federales. Se pudo observar que el mayor número de APs que iniciaron el monitoreo ocurrió generalmente alrededor de un año después de los primeros cursos de puntos focales. El resultado de la evaluación de reacción mostró que los cursos contribuyen a mejorar el desempeño profesional de los estudiantes: el 92% respondió que el curso contribuyó a mejorar su desempeño laboral y el 87% señaló confianza en el uso de los conocimientos y habilidades adquiridos. Es un gran reto desarrollar cursos para el monitoreo de la biodiversidad en el panorama de amplia diversidad ambiental, social y económica, por lo que se necesitan diferentes estrategias para desarrollar mejor los conocimientos, habilidades y competencias de los estudiantes. En este sentido, se destacan las siguientes estrategias: las diferentes modalidades de enseñanza utilizadas (presencial, híbrida, aprendizaje virtual), el formato de cobertura de los cursos (local – una sola AP o regional/nacional – varias APs), la construcción colectiva, desde el diseño del curso hasta el análisis de datos, y la variedad de herramientas pedagógicas utilizadas en el proceso de aprendizaje.O objetivo deste estudo de caso é avaliar as estratégias de capacitação que vêm sendo implementadas desde 2013 no ciclo de capacitação do Programa Monitora.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
