ABSTRACT 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. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Leaf litter is an important component related to nutrient cycling and conservation of soil biodiversity. In this context, the objective of our study was to investigate the relationship between soil and leaf litter in different forest communities in sub-regions of the Pantanal (Nhecolândia and Abobral/Miranda). To this end, we collected soil and leaf litter samples from 152 sample plots divided in physiognomies regionally called as Cordilheira, Capão, Murundu, Corixo and Cambará/Canjiqueira forest. In the laboratory, analytical determinations were conducted for 22 soil attributes and 11 elements of the chemical composition of the leaf litter. The forest communities showed a great well-defined edaphic gradient encompassing environments with high natural fertility soils (Capão and Cordilheira Abobral/Miranda), acidic soils with a high proportion of soluble Al3+ (Cambará/Canjiqueira, and Corixo), and poorly developed soils with a predominantly sandy texture (Nhecolândia region, Cordilheira and Murundu). Soil attributes are significantly related to the chemical composition of litter, as indicated by correlations between N, P, Ca, Mg, Mn and the C/N ratio with physical, chemical and soil organic matter attributes. This study revealed the interaction of soils with the chemical composition of litter, constituting an ecosystem service, in forest communities in the Brazilian Pantanal. biodiversity context subregions sub regions Nhecolândia Abobral/Miranda.

ABSTRACT We investigated the influence of Quaternary climate fluctuations on the current distribution of three species of Leguminosae (Fabaceae) occurring in the Chaco. Potential distribution models of Bauhinia hagenbeckii, Muellera nudiflora and Neltuma rubriflora with a supposed endemism area were generated. The Last Interglacial, Last Glacial Maximum, Holocene Middle and current scenarios were used. The species showed a potential distribution according to the South American biogeographic history regarding the glacier regression and the formation of the Dry Diagonal. The models for each Quaternary event exhibited a tolerable AUC ≥ 0.9 for the validations. The LGM was the event that favoured the current species establishment areas in the Dry Diagonal. Quaternary climatic events were related to the current Leguminosae distribution. Bauhinia hagenbeckii and Neltuma rubriflora present similar areas of environmental suitability. Muellera nudiflora models with areas of environmental suitability were larger for the LIG and Holocene than for areas from other periods. All scenario models (LGM, HM and current scenario) highlighted the potential distribution of the three species concomitant with the glacier regression events and were consistent with the history of formation of South American dry areas.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

ABSTRACT The distributions of species of Fabaceae are strongly related to the soil. Their presence can alter restrictive conditions and favour the establishment of other species. However, it is still not known how the relationship between species of Fabaceae and edaphic factors interact in structuring woody Chaco vegetation. In this context, we aimed to test the hypothesis that restrictive edaphic conditions can explain the difference in floristic patterns of two types of vegetation through their species representativeness of Fabaceae. We analysed floristic consistency between wooded and forested Chaco to address how spatial and environment components might explain differences between them along with the effects of the interaction between Fabaceae and the soil. We observed that the association between environmental and spatial variables was more important than any individual factor in explaining the structuring of the communities. Both the percentage of species of Fabaceae present and the soil influence the structure of the two types of vegetation. Species of Fabaceae have greater potential as indicators in the wooded Chaco. Therefore, we suggest the interaction between soil types and species of Fabaceae plays a role during the structuring of the communities through the establishment of these species in more restrictive soils.

ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonization-related traits and determines taxonomic composition of subplots. A total of 5,078 subplots were censused with leaf and fruit traits and height measurements being determined for each tree of each species, and with averaged-abundance-weighted values calculated for each subplot. A dendrogram was generated from the taxonomic composition of subplots using Sorensen similarity and UPGMA clustering. A total of 74,335 trees of 178 species were recorded. Clustering revealed five main groups of subplots that were tested against each other and found to differ in terms of average leaf width, leaf-width/petiole-width, wood density, mean height, height mode, fruit width and fruit length. Greater leaf averages in subplots were associated with greater fruit averages, and with higher wood densities and greater heights among groups of subplots, revealing that heterogeneity during colonization directed the communities of the 50-ha plot. The averaged values of functional traits detected subplots associated with conditions favorable to colonization, thereby reinforcing the growth-survival trade-off hypothesis.

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital’s electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

ABSTRACT The objective of this study was to model the potential effect of future climate change on the distribution of a tree species indicator of Cerrado. For the modeling, we used 488 occurrence points of the species and also bioclimatic variables corresponding to 2050 and 2070, for the more optimistic and pessimistic scenarios. All generated models were classified as consistent, getting an area under curve higher than 0.90. The current modeling of Connarus suberosus showed that 88% of the area with a high probability of species occurrence is inside the Cerrado domain. Future projections suggest losses in the environmental suitability area around 40.8% and 44.8% in the optimistic scenario, 61.6% and 81.6% in the pessimistic scenario considering 2050 and 2070, respectively. Furthermore, we found a tendency of the C. suberosus to move in the Atlantic Forest direction. This modeling is an alert that the C. suberosus will suffer from future climate change.

This study describes the influence of edaphic factors on the floristic composition of an area of cerradão (woodland savanna) in the city of Campo Grande, located in the Brazilian central-west. In 10 plots (5 × 20 m each), we evaluated all trees with a diameter at breast height > 4.77 cm. Soil samples were analyzed for each plot in order to determine edaphic variables correlated with species composition. We sampled 1180 individuals of 61 species. The evenness index was 0.74, which indicates uneven distribution of species, which was explained by a high abundance of Qualea parviflora, Curatella americana, Qualea grandiflora, Terminalia argentea and Astronium fraxinifolium. We registered more trees in the smallest diameter class and in the middle layer of the vertical structure. The soil was dystrophic with a clay texture, which explains the higher abundance of species related to dystrophic cerradão. However, we also found some trees typical of mesotrophic cerradão and deciduous forests, which could be attributable to the presence of patches of fertile soil within the dystrophic cerradão or could indicate that those mesotrophic species are tolerant of lower levels of soil nutrients.

O objetivo deste trabalho foi avaliar a estrutura metabólica e genética de comunidades bacterianas em Latossolo de cerrado sob vegetação nativa ou cultivado em sistema de rotação soja/milho sob preparo convencional e plantio direto. Foram utilizadas microplacas EcoPlate para determinar o perfil e a diversidade metabólica das comunidades bacterianas, e eletroforese em gel com gradiente desnaturante (DGGE) para avaliar a estrutura genética. O teste estatístico de Mantel foi utilizado para avaliar a relação entre a estrutura metabólica e a genética. A comunidade bacteriana sob vegetação nativa apresentou perfil metabólico diferente do encontrado em solos cultivados. No solo cultivado com soja sob preparo convencional, o padrão de utilização das fontes de carbono diferenciou-se dos demais tratamentos. Com base nos resultados de DGGE, a comunidade bacteriana sob vegetação nativa apresentou 35% de similaridade com as de áreas cultivadas. Foram formados grupos distintos de comunidades bacterianas do solo entre as áreas sob preparo convencional e plantio direto. Houve correlação significativa de 62% entre as matrizes geradas pelas microplacas EcoPlate e pela DGGE. Variações no perfil metabólico estão relacionadas às variações na estrutura genética das comunidades bacterianas do solo.
The objective of this work was to evaluate the metabolic and genetic structure of bacterial communities in a cerrado Oxisol under native vegetation or cultivated in a soybean/maize rotation system under conventional tillage and no tillage. EcoPlate microplates were used to determine the metabolic profile and diversity of bacterial communities, and denaturing gradient gel electrophoresis (DGGE) to assess the genetic structure. The Mantel statistic test was used to evaluate the relationship between the metabolic and the genetic structure. The bacterial community under native vegetation showed a different metabolic profile than that of cultivated soils. In the area cultivated with soybean under conventional tillage, the carbon source utilization pattern differed from the other treatments. Based on the DGGE results, the bacterial community under native vegetation showed 35% similarity to the ones found under cultivation. Distinct groups of soil bacterial communities were formed between the areas under conventional tillage and no tillage. A significant correlation of 62% was observed between matrices generated by EcoPlate microplates and by DGGE. Variations in the metabolic profile are related to changes in the genetic structure of soil bacterial communities.

INTRODUÇÃO: O tratamento endovascular da doença aterosclerótica carotídea vem evoluindo continuamente, embora possam ocorrer complicações embólicas ou isquêmicas, mesmo com o uso dos sistemas de proteção cerebral. Este estudo teve como objetivo avaliar os resultados de uma série inicial de pacientes que utilizaram o sistema de reversão de fluxo durante angioplastia carotídea. MÉTODOS: Estudo prospectivo, não-randomizado, não-controlado, realizado em um único centro. Foram incluídos pacientes assintomáticos com lesão > 70% ou sintomáticos com lesão > 50% em artéria carótida interna. Foi utilizado o sistema de reversão de fluxo, com pré-dilatação em casos selecionados e uso de stents de células abertas em todos os casos. Avaliou-se a ocorrência de acidentes vasculares encefálicos (AVEs) maiores e menores, ataques isquêmicos transitórios (AITs), infarto agudo do miocárdio (IAM) e óbito até 30 dias pós-procedimento. RESULTADOS: Entre setembro de 2010 e fevereiro de 2011 foram realizadas angioplastias carotídeas em 17 pacientes, a maioria do sexo masculino (70,6%), com média de idade de 66,7 ± 8 anos, sendo 17,6% diabéticos. Cerca de metade dos pacientes era sintomática, 5 pacientes tinham história de AVE prévio (29,4%) e 3, de AIT (17,7%) prévio. Sucesso técnico foi obtido em 100% dos casos. Houve um caso de óbito (5,9%), 24 horas após o procedimento, em paciente de alto risco cirúrgico tratado na fase evolutiva de IAM por apresentar AITs de repetição. Não ocorreram casos de AVE maior ou menor ou AIT durante o período de acompanhamento. CONCLUSÕES: Neste estudo, o sistema de reversão de fluxo mostrou ser eficiente e seguro em pacientes submetidos a angioplastia carotídea.
BACKGROUND: The endovascular treatment of carotid atherosclerotic disease has continuously evolved, although ischemic or embolic complications may occur even with the use of cerebral protection systems. This study was aimed at evaluating the perioperative results of an initial series of patients using the flow reversal system during carotid angioplasty. METHODS: This was a prospective, non-randomized, non-controlled, single-center study. Asymptomatic patients with lesions > 70% or symptomatic patients with lesions > 50% in the internal carotid artery were included. The flow reversal system was used with pre-dilation in selected cases and open-cell stents were used in all cases. We evaluated the occurrence of major and minor strokes, transient ischemic attacks (TIAs), acute myocardial infarction (AMI) and death within 30 days after the procedure. RESULTS: Between September 2010 and February 2011 carotid angioplasty was performed in 17 patients, most of them male (70.6%), with mean age of 66.7 ± 8 years, of which 17.6% were diabetic. Approximately half of the patients were symptomatic, 5 patients had a prior history of stroke (29.4%) and 3 had TIA (17.7%). Technical success was achieved in 100% of the patients. There was one death (5.9%), 24 hours after the procedure in a high surgical risk patient treated in the evolution phase of an AMI due to repetitive TIAs. There were no cases of major or minor strokes or TIAs during the follow-up. CONCLUSIONS: In our study, the flow reversal system proved to be effective and safe in patients undergoing carotid angioplasty.

As saúvas (Atta spp.) estão amplamente distribuídas pelo continente Sul-Americano e são consideradas importantes componentes do ecossistema neotropical. Diversos estudos têm demonstrado o efeito de formigueiros no enriquecimento do solo e na facilitação ao estabelecimento de espécies vegetais. Possivelmente o enriquecimento do solo seja devido ao acúmulo de matéria orgânica decomposta em câmaras de descarte (lixo) no interior das colônias. Entretanto, pouco se sabe sobre a composição química do lixo de formigas cortadeiras. O objetivo do presente trabalho foi comparar os teores de nutrientes do lixo produzido por colônias de Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae), em laboratório, mantidas com folhas de duas espécies de plantas. Os tratamentos foram dois tipos de substrato (Acalypha sp. ou Bauhinia sp.), repetidos quatro vezes. Oito colônias foram divididas em dois grupos (n = 4), e cada grupo foi mantido com apenas um tratamento. Após 30 dias de experimento, as amostras de folhas e lixo foram secas em estufa (70 ºC) e submetidas à digestão ácida, para determinação das concentrações de N, P, K, S, Ca e Mg. Diferenças nas concentrações dos macronutrientes entre os tratamentos (lixo ou folha) foram comparadas por meio de ANOVA e teste T. As concentrações de nutrientes no lixo foram sempre maiores do que nas folhas, independentemente da espécie cortada. Folhas de Acalypha sp. apresentaram concentrações significativamente maiores do que folhas de Bauhinia sp. com relação aos teores de P, Ca, Mg e S; entretanto, as concentrações do lixo em todos os formigueiros foram muito próximas, indicando incorporação adicional de nutrientes por meio do fungo, excreções e, ou, cadáveres no lixo. Esses resultados indicam que, independentemente do substrato cortado, o lixo produzido apresenta maiores concentrações de nutrientes do que as folhas, sendo importante locus de reciclagem de nutrientes no ecossistema. O lixo pode ser uma das principais razões para o aumento da concentração de nutrientes em solos de formigueiros.
Leaf-cutting ants (Atta spp.) are widely distributed in South America, and are considered to be important components of the neotropical ecosystems. Several studies have demonstrated the effect of ant-nesting in soil enrichment, thus facilitating vegetation succession. Possibly, this enrichment is due to decomposed organic matter concentration after disposal of nest refuse in the deep soil by the colonies. However, little is known about the chemical composition of refuse material produced by leaf-cutting ants. The present work aimed to compare the macronutrient concentration in nest refuse and leaves of two different harvested plants (Acalypha sp. or Bauhinia sp.) in colonies of Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae) maintained in laboratory. Eight colonies were divided into two groups (n = 4), and each one was maintained with only one feed type. After 30 days of experiment, samples of leaves and refuse were oven-dried at 70 ºC and subjected to acid digestion for chemical determination of total N, P, K, S, Ca and Mg. Differences in concentrations of macronutrients in both leaves and refuse were compared using ANOVA and T test. Nutrient concentration in the refuse material was consistently higher than in leaves, for both plants. Acalypha sp. leaves showed greater nutrient concentration than those of Bauhinia sp., while the concentration of all refuses were very similar. This indicates an additional enrichment of nutrients in the refuse material by either ant carcasses, fungus cycling or excretions. Results suggest that nests of leaf-cutting ant are important loci of nutrient recycling of the ecosystem. Moreover, the refuse may represent an important factor for chemical enrichment in soils influenced by leaf-cutting ants.

As formigas cortadeiras (Atta e Acromyrmex) são consideradas importantes pragas na agricultura e silvicultura, mas pouco se sabe sobre os reais danos dessas espécies. Uma forma bastante difundida de avaliação do dano é por meio do cálculo da taxa de conversão, dividindo-se o peso do material cortado pelo peso de lixo produzido pelas colônias. Foi levantada a hipótese de que a qualidade do substrato cortado pode influenciar no forrageamento das operárias, alterando a taxa de conversão e dificultando as estimativas de dano. A taxa de conversão de oito colônias de Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae) foi calculada com duas espécies vegetais com diferentes concentrações de lignina e celulose, para testar essa hipótese. Colônias mantidas com folhas de baixa qualidade (razão lignina/celulose elevada) tiveram maior forrageamento e produziram mais lixo. Entretanto, a taxa de conversão das colônias foi semelhante com essas duas plantas (média = 1,54). Esse valor está dentro da variação encontrada para outras espécies no campo (1,5-1,8), indicando um fator semelhante de conversão entre os gêneros Atta e Acromyrmex. O consumo médio de material vegetal, em termos de pesos seco e fresco, de uma colônia de A. sexdens rubropilosa com 4.500 operárias, foi estimado em 520 e 1.100 g/ano, respectivamente.
Leaf-cutting ants (Atta and Acromyrmex) are important pests in agriculture and forestry, although few data exist on the actual damage caused by these species. A model used to evaluate damage by leaf-cutting ants are estimates of the conversion factor, which is the ratio between the weight of material cut by the ants and the refuse produced by the colonies. The hypothesis that substrate quality influences foraging by workers, modifying the conversion factor and impairing damage estimates was put forward. To test this hypothesis, the conversion factor was calculated for eight colonies of Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae), using two plant species, with different lignin and cellulose concentrations. Colonies maintained with low quality leaves (high lignin/cellulose ratio) presented higher foraging activity and produced more refuse than colonies maintained with high quality leaves. However, the conversion factors obtained for the two groups of leaf-cutting ant colonies (average = 1.54) was within the variation found for other species in the field (1.5 - 1.8), indicating a similar conversion factor in Atta and Acromyrmex. The average consumption in both dry and fresh weight of plant material of a colony of Atta sexdens rubropilosa with 4,500 workers was estimated as 520 and 1,100 g/year, respectively.
