ABSTRACT The objective of this study was to examine the effect of the increasing levels of inclusion of palm kernel cake (PKC) in the diet on the performance of feedlot heifers. Forty-eight Nelore heifers with an initial weight of 274 ± 4.58 kg, at 24 months of age, were confined for 98 days in a feedlot. The animals were allocated to the four treatments in a completely randomized design. Treatments consisted of PKC levels of 0 (control), 10, 20, and 30% in the total dry matter of the diet. The roughage:concentrate ratio in the diets was 30:70. Ether extract intake increased, whereas the intakes of non-fiber carbohydrates and total digestible nutrients decreased with the inclusion of PKC. The apparent digestibility of all nutrients decreased, as well as the amounts of nitrogen digested and retained. Microbial protein synthesis and its efficiency also declined. The inclusion of up to 20% PKC increased feeding time and reduced rumination time of heifers. Intake and rumination efficiencies decreased with the inclusion of PKC in the diet. Final weight and average daily gain did not change, but feed efficiency increased with the inclusion of PKC. The inclusion of up to 30% PKC in the diet of feedlot heifers is recommended.

ABSTRACT This study used a pedigree analysis to monitor trends in the genetic structure of the Mangalarga breed and identify factors that could impact its genetic variability. For this, genealogical information was used from the Associação Brasileira dos Criadores de Cavalo da Raça Mangalarga, considering as total population (TP) the animals born between 1919 and 2018 (n = 206,426) and as reference population (RP) those born between 2009 and 2018 (n = 20,539), which is the most recent generation according to the average generation interval calculated for the breed of 9.37 years. We evaluated the number of male and female births per year, foals produced by Mangalarga breeding animals, using the ENDOG 4.8, generation interval, proportion of known ancestors per parental generation, number of equivalent generations known per animal, inbreeding coefficient, increase in inbreeding, average relatedness (AR), effective population size, effective number of founders, effective number of ancestors, and founder genome equivalent. The number of equivalent generations known per animal increased over time, reaching an average of 2.75 in TP and 4.88 in RP. The calculated F was 2.26% for TP and 5.57% for RP, while AR was 2.41% for TP and 4.10% for RP. The effective population size was 40.85 for TP and 38.89 for RP. The 206,426 registered Mangalarga horses (TP) were derived from the genetic contribution of 9,011 founders and 8,908 ancestors, whereas those registered in or after 2009 (RP) originated from 2,662 founders and 2,193 ancestors. The effective number of founders represented 1.11 and 1.35% of the total number of founders in TP and RP, respectively. For RP, 11 animals accounted for 29.21% of the genetic pool of the breed. The analysis of population parameters estimated in the present study indicates that the Mangalarga horse population was formed through uneven contributions from founders and ancestors; therefore, genetic management of the breed is required to restrict average inbreeding from increasing over generations. variability this (TP 191 201 n 206426 206 426 RP (RP 200 20,539, 20539 20,539 , 20 539 20,539) 937 9 37 9.3 years year 48 4 8 4.8 coefficient AR, (AR) time 275 2 75 2.7 488 88 226 26 2.26 557 5 57 5.57 241 41 2.41 410 10 4.10 4085 40 85 40.8 3889 38 89 38.8 206,42 9011 011 9,01 8908 908 8,90 2662 662 2,66 2193 193 2,19 111 1 1.1 135 35 1.35 respectively 2921 29 21 29.21 therefore 19 20642 42 2053 20,53 53 93 3 9. 4.

Abstract Objective Pregnancy in women with lupus poses a higher risk of complications compared with the general population. The present study aimed to determine and describe the obstetric and neonatal outcomes of pregnant women with lupus. Materials and Methods We conducted an observational retrospective study of pregnant women with the diagnosis of lupus, who were selected and followed at the Maternal-Fetal Medicine Clinic of our institution between January 2013 and July 2018. We analyzed 59 pregnancies and 52 newborns, and collected data regarding sociodemographic features, the preconception period, pregnancy, childbirth, postpartum and the newborn. A descriptive analysis of the variables was performed. Results In 58% of the cases, the pregnancy was uneventful. We registered flares in 25% of the cases, preeclampsia in 3%, fetal growth restriction in 12%, gestational loss in 10%, preterm labor in 10%, postpartum complications in 20%, and small for gestational age newborns in 17% of the cases. Conclusions Most pregnancies in women with lupus have favorable obstetric and neonatal outcomes. Prenatal counseling, adequate multidisciplinary surveillance, and optimized treatment of the disease are fundamental pillars for these good results.

RESUMO: Objetivou-se analisar as alterações demográficas e biométricas dos animais registrados da raça Mangalarga, ao longo das décadas. Foram utilizadas informações de 206.428 equinos Mangalarga, extraídas do sistema de registro genealógico da Associação Brasileira de Criadores de Cavalos da Raça Mangalarga. Dos animais nascidos entre 1930 e 2018, foram consideradas informações referentes ao sexo, data de nascimento, pelagem, localização do criatório, pontuação obtida no ato do registro genealógico e três medidas corporais dos equinos. Utilizando a medida de altura à cernelha e os perímetros torácico e de canela foram calculados cinco índices morfométricos. Os resultados foram submetidos à análise de variância, utilizando delineamento inteiramente ao acaso em esquema de parcelas subdivididas, sendo as parcelas compostas pelos sexos e as subparcelas constituídas pelas décadas de seleção. Entre 1930 e 1990 houve aumento progressivo na emissão de registros genealógicos, com destaque para as décadas de 70 e 80, quando se registrou maior taxa de crescimento do rebanho. Em 2018 identificou-se criatórios da raça Mangalarga em 23 estados brasileiros, sendo o Estado de São Paulo detentor do maior rebanho, seguido de Minas Gerais e Bahia. Entre 1970 e 2018 registrou-se aumento na altura à cernelha das fêmeas, garanhões e machos castrados, que se tornaram 5,1 cm, 3,1 cm e 2,1 cm mais altos, respectivamente. Enquanto o perímetro torácico dos garanhões aumentou 3,3 cm, o perímetro de canela das fêmeas reduziu 0,34 cm. Concluiu-se que a raça Mangalarga está distribuída por todo o Brasil, com destaque para a região sudeste. Independente do sexo, a seleção aplicada à raça tornou os equinos Mangalarga mais altos. Além disso, os garanhões ficaram mais pesados e com maior perímetro torácico e as fêmeas tornaram-se hipométricas.
ABSTRACT: This study analyzed the demographic and biometric changes in registered animals of the Mangalarga breed over the decades. Information from 206,428 Mangalarga horses born between 1930 and 2018 extracted from the genealogic registry system of the Associação Brasileira de Criadores de Cavalos da Raça Mangalarga was employed. The data referred to sex, birth date, fur coat, breeding site location, score achieved at genealogic registration, and three body measurements. Height at withers and the thoracic and cannon bone circumferences were used to calculate five morphometric indices. Results were submitted to analysis of variance using a completely randomized split-plot design where the plots comprised the sexes and the split-plots comprised the decades of selection. Between 1930 and 1990, genealogic registrations progressively increased, particularly in the 1970s and 80s, when the herd experienced the highest growth rate. In 2018, Mangalarga breeding sites were reported in 23 Brazilian states and the states of São Paulo, Minas Gerais, and Bahia held the largest herds. Between 1970 and 2018, the height at withers of mares, stallions, and geldings increased by 5.1, 3.1, and 2.1 cm, respectively. The thoracic circumference of stallions increased by 3.3 cm and the cannon bone circumference of mares decreased by 0.34 cm. It is concluded that the Mangalarga breed is found across Brazil, especially in the Southeast region. Irrespective of sex, the selection of the breed has led to taller Mangalarga horses. In addition, the stallions became heavier and gained thoracic circumference, while mares became hypometric.

Abstract We investigate the impact of yacon syrup consumption on glycemic, lipid and metabolic endotoxemia in healthy subjects. Thus, 32 healthy were randomized into two groups that consumed 40 g of yacon syrup/day (= 8.74 g FOS/day) or a placebo, for 2-weeks. Anthropometric assessments, gastrointestinal effects, glycemic and lipid profile, and LPS were performed at the beginning and at the end of the study. The results obtained shown that the 2-weeks consumption of yacon syrup does not promote serum LPS alteration in healthy volunteers. Moreover, the glycemic and lipid profile were also similar between the groups before and after the intervention. Yacon syrup did not affect blood lipid, glucose or metabolic endotoxemia. However, it is possible that positive effects of yacon syrup will turn evident only in a long-term intervention. Further studies are needed to assess the long-term effect of yacon syrup consumption, and its use in obese and diabetic individuals.

RESUMO Objetivo: Gerar valores de referência para espirometria em crianças brasileiras de 3-12 anos de idade e comparar os resultados obtidos com as equações em uso no Brasil. Métodos: Foram incluídas crianças sadias de 3-12 anos recrutadas em 14 centros (dados primários) e resultados de espirometria de crianças com as mesmas características de seis bancos de dados (dados secundários). As equações quantílicas foram geradas após transformações logarítmicas dos dados espirométricos e antropométricos. A classificação por cor da pele foi autodeclarada. Os resultados obtidos foram comparados com os previstos nas equações em uso no Brasil para testar sua adequação. Resultados: Foram incluídos 1.990 indivíduos de 21 fontes de dados primários e secundários, sendo 1.059 (53%) do sexo feminino. Equações para VEF1, CVF, VEF1/CVF, FEF25-75% e FEF25-75%/CVF foram geradas para crianças brancas e para crianças negras e pardas. Os logaritmos da estatura e da idade e a cor da pele foram os melhores preditores para VEF1 e CVF. Os resultados obtidos foram significativamente maiores do que as estimativas geradas pelas equações em uso no Brasil, tanto para valores previstos quanto para o limite inferior da normalidade, particularmente em crianças negras e pardas. Conclusões: Novas equações espirométricas foram geradas para crianças brasileiras de 3-12 anos de cor branca, negra e parda. As equações atualmente em uso no Brasil parecem subestimar a função pulmonar de crianças brasileiras menores de 12 anos de idade e deveriam ser substituídas pelas equações propostas neste estudo.
ABSTRACT Objective: To generate reference values for spirometry in Brazilian children 3-12 years of age and to compare those values with the values employed in the equations currently in use in Brazil. Methods: This study involved healthy children, 3-12 years of age, recruited from 14 centers (primary data) and spirometry results from children with the same characteristics in six databases (secondary data). Reference equations by quantile regressions were generated after log transformation of the spirometric and anthropometric data. Skin color was classified as self-reported by the participants. To determine the suitability of the results obtained, they were compared with those predicted by the equations currently in use in Brazil. Results: We included 1,990 individuals from a total of 21 primary and secondary data sources. Of those, 1,059 (53%) were female. Equations for FEV1, FVC, the FEV1/FVC ratio, FEF between 25% and 75% of the FVC (FEF25-75%) and the FEF25-75%/FVC ratio were generated for white-, black-, and brown-skinned children. The logarithms for height and age, together with skin color, were the best predictors of FEV1 and FVC. The reference values obtained were significantly higher than those employed in the equations currently in use in Brazil, for predicted values, as well as for the lower limit of normality, particularly in children with self-reported black or brown skin. Conclusions: New spirometric equations were generated for Brazilian children 3-12 years of age, in the three skin-color categories defined. The equations currently in use in Brazil seem to underestimate the lung function of Brazilian children 3-12 years of age and should be replaced by the equations proposed in this study.

Resumen El objetivo fue evaluar la viabilidad económica, a través de diferentes estrategias de suplementación, de las etapas post destete y finalización del ganado bovino suplementado en pastoreo de Brachiaria brizantha cv. Marandú durante las temporadas de lluvias y secas. El periodo experimental fue de 447 días. El estudio comprendió las etapas post destete y finalización de 22 bovinos machos (1/2 Holstein-Cebú) enteros con un peso inicial promedio de 164.09 ± 12.13 kg y una edad promedio de 7 meses. Los animales se distribuyeron en un diseño aleatorio con 11 repeticiones por tratamiento. Se probaron las siguientes estrategias de suplementación: estrategia 1 (E1): mezcla de minerales en el 1er y 3er periodos y suplementación de proteína y energía al 0.2% del peso corporal (PC) en el 2do periodo; y estrategia 2 (E2): suplementación de proteína-energía a 0.4% PC en los períodos 1º y 3º, y suplementación de proteína-energía a 0.6% PC en el 2º período. La estrategia 1 dio como resultado un menor costo por arroba producido y un menor costo por hectárea, generando una mayor ganancia neta por hectárea y, en consecuencia, una mayor tasa interna de retorno. Cuando se dispone de forraje, la suplementación de minerales suministrada durante la temporada de lluvias, asociada con bajos niveles de suplementación de proteína y energía en la estación seca (S1), es de mayor atractivo económico para el desarrollo del sistema, ya que conduce a mayores tasas internas de valores de retorno y valores netos presentes en todo el periodo.
Abstract The objective of this study was to evaluate the economic viability, through different supplementation strategies, of the post-weaning and finishing stages of cattle supplemented on Brachiaria brizantha cv. Marandu pastures during the rainy and dry seasons. The experimental period was 447 d. The study comprised the post-weaning and finishing stages of 22 intact male crossbred (½ Holstein-Zebu) cattle with an average initial weight of 164.09 ± 12.13 kg and an average age of 7 mo. The animals were distributed in a randomized design with 11 replications per treatment. The following supplementation strategies were tested: strategy 1 (S1): Mineral mix in the 1st and 3rd periods and protein-energy supplementation at 0.2 % of the body weight (BW) in the 2nd period; and strategy 2 (S2): protein-energy supplementation at 0.4 % BW in the 1st and 3rd periods, and protein-energy supplementation at 0.6 % BW in the 2nd period. Strategy 1 resulted in a lower cost per arroba produced and lower cost per hectare, generating a greater net profit per hectare and consequently a higher internal rate of return. When herbage is available, mineral supplementation supplied during the rainy season, associated with low levels of protein-energy supplementation in the dry season (S1), is of greater economic attractiveness for the development of the project, as it leads to higher internal rates of return and net present values in the entire period.

ABSTRACT This study aimed to determine the participation frequency and competitive performance of Campolina and Mangalarga Marchador horses in national shows concerning marcha type, sex, and age. To that end, the trial results of national horse shows between 2007 and 2017, comprising 1,781 Campolina and 5,239 Mangalarga Marchador animals, were extracted from the databases of the breeders’ associations of each breed. The results regarding participation frequency in these events and the performance achieved by horses were grouped by breed, marcha type, sex, and age group and then subjected to frequency distribution tests. In both breeds, most animals attended only one national show. However, when the specimens were separated by marcha type, sex, and age, it was observed that 54.39% of marcha batida Campolina males competed twice, with greater participation of adult horses (41.41%) than of young ones (22.22%). For Mangalarga Marchador, irrespective of gait type, the proportion of adult horses (67.22%) that competed was higher than that of young ones (25.63%). For marcha picada competitors, the proportion between young (13.97%) and adult (81.91%) was even higher. It was concluded that, over their competitive careers, most horses of either breed attended only one national show, that marcha picada animals usually compete only when adults, and that marcha batida females compete more often when young. In addition, the age group in which competitors achieve their best performances varies according to the specimen.

BACKGROUND Visceral Leishmaniasis (VL) is an infectious disease that is a significant cause of death among infants aged under 1 year and the elderly in Brazil. Serodiagnosis is a mainstay of VL elimination programs; however, it has significant limitations due to low accuracy. OBJECTIVE This study aimed to evaluate three recombinant Leishmania infantum proteins (rFc, rC9, and rA2) selected from previous proteomics and genomics analyses to develop enzyme-linked immunosorbent assay (ELISA) and immunochromatographic tests (ICT) for the serodiagnosis of human VL (HVL) and canine VL (CVL). METHODS A total of 186 human (70 L. infantum-infected symptomatic, 20 other disease-infected, and 96 healthy) and 185 canine (82 L. infantum-infected symptomatic, 27 L. infantum-infected asymptomatic, and 76 healthy) sera samples were used for antibody detection. FINDINGS Of the three proteins, rA2 (91.5% sensitivity and 87% specificity) and rC9 (95.7% sensitivity and 87.5% specificity) displayed the best performance in ELISA-HVL and ELISA-CVL, respectively. ICT-rA2 also displayed the best performance for HVL diagnosis (92.3% sensitivity and 88.0% specificity) and had high concordance with immunofluorescence antibody tests (IFAT), ELISA-rK39, IT-LEISH®, and ELISAEXT. ICT-rFc, ICT-rC9, and ICT-rA2 had sensitivities of 88.6%, 86.5%, and 87.0%, respectively, with specificity values of 84.0%, 92.0%, and 100%, respectively for CVL diagnosis. MAIN CONCLUSIONS The three antigens selected by us are promising candidates for VL diagnosis regardless of the test format, although the antigen combinations and test parameters may warrant further optimisation.

RESUMO: Este estudo buscou identificar componentes principais (CP) que explicam os maiores percentuais de variância total e que melhor caracterizam cabritos mestiços da raça Anglo Nubiana, quanto à medidas morfológicas obtidas in vivo, e na carcaça de 28 animais com 8 meses de idade. Foram conduzidas duas análises de componentes principais, sendo uma para 19 características de carcaça e outra para seis características morfométricas in vivo. Os cinco primeiros CP explicaram 82,54% da variância total das 19 características incluídas nessa análise. Estes componentes foram chamados de: CP1 - Tamanho da Carcaça, CP2 - Condição Corporal, CP3 - Largura da Carcaça, CP4 - Profundidade do Tórax e, CP5 - Comprimento do Pernil. Os dois primeiros componentes principais das morfometrias obtidas in vivo explicaram 78,86% da variância total e foram chamados de CP1 - Tamanho in vivo e CP2 - Conformação in vivo.
ABSTRACT: This study aimed to identify the principal components (PC) that explain the highest percentages of total variance and best characterize the in vivo and carcass morphologies of Anglo-Nubian crossbred goats. Nineteen carcass morphometric traits and six in vivo morphometric traits were measured in 28 kids at eight months of age. Principal component analysis indicated that five PC were able to explain 83.57% of the total variance in the 19 original carcass traits. Those components were termed PC1-Carcass Size, PC2 - Body Condition, PC3-Carcass Width, PC4-Chest Depth, and PC5 - Hindquarter. For in vivo morphometric traits, the first two principal components explained 78.86% of the total variance. These components were called PC1-In vivo Size and PC2-In vivo Conformation.

Abstract Glycerin is an organic compound with an alcoholic function and can be esterified into fatty acids to form triglycerides. Due to the increasing availability of glycerin, studies that determine the best level of its inclusion in diets for ruminants are needed. This study evaluated the effects of glycerin supplementation on the proximate composition and fatty acid profile of the longissimus lumborum of heifers fed on Brachiaria brizantha pasture. Thirty-six heifers were distributed in a totally randomized design with four treatments (G0.0 = without glycerin, G4.6 = 4.6% glycerin, G9.3 = 9.3% glycerin and G14.3 = 14.3% glycerin). The addition of glycerin decreased the tetradecanoic and octadecanoic fatty acids but increased the pentadecanoic, heptadecanoic, heptadecenoic, eicosanoic, eicosatetraenoic and docosatetraenoic fatty acids. The saturated (SFA), monounsaturated (MUFA) and omega-3 (n-3) fatty acid concentrations were similar across the diets. However, the polyunsaturated (PUFA) concentrations and the PUFA:MUFA and n-6:n-3 ratios increased with the inclusion of glycerin in the diet. Glycerin levels up to 14.3% (corresponding to a substitution of 50.5% of corn for this byproduct as an energy source) did not alter the proximate composition of the meat but improved the fatty acid profile of the longissimus lumborum muscle and, consequently, increased the meat quality, potentially providing benefits for human health.
Resumen La glicerina es un compuesto orgánico con una función alcohólica que puede esterificarse en ácidos grasos para formar triglicéridos. Debido a su disponibilidad cada vez mayor, se necesitan estudios que indiquen el mejor nivel de inclusión en las dietas para los rumiantes. Este estudio evaluó los efectos de la glicerina sobre la composición próxima y el perfil de ácidos grasos de Longissimus lumborum de novillas suplementadas con pasto de Brachiaria brizantha. Se distribuyeron 36 vaquillas en un diseño totalmente aleatorizado con cuatro tratamientos (G0.0 = sin glicerina, G4.6 = 4,6% de glicerina, G9.3 = 9.3% de glicerina y G14.3 = 14.3% de glicerina). La adición de glicerina disminuyó los ácidos grasos tetradecanoico y octadecanoico, pero aumentó los ácidos grasos pentadecanoico, heptadecanoico, heptadecenoico, eicosanoico, eicosatetraenoico y docosatetraenoico. Las concentraciones de ácidos grasos saturados (SFA), monoinsaturados (MUFA) y omega-3 (n-3) fueron similares en todas las dietas. Sin embargo, las concentraciones de poliinsaturados (PUFA) y los niveles de PUFA: MUFA y n-6: n-3 aumentaron con la inclusión de glicerina en las dietas. Los niveles de glicerina hasta 14.3% (que corresponden a una sustitución del 50.5% de maíz por este subproducto como fuente de energía) no alteraron la composición proximal de la carne pero mejoraron el perfil de ácidos grasos del músculo Longissimus lumborum y, en consecuencia, aumentaron la carne calidad, potencialmente proporcionando beneficios para la salud humana.

RESUMO Objetivou-se com este estudo identificar e quantificar os constituintes do óleo essencial de Zanthoxylum caribaeum e avaliar o potencial antimicrobiano de diferentes extratos vegetais e do óleo essencial desta planta frente a diferentes sorotipos de Salmonella enterica, de maior ocorrência e isoladas na região oeste do Paraná, Brasil. A extração do óleo essencial foi realizada utilizando aparelho Clevenger e a composição química foi determinada por Cromatografia Gasosa acoplada a Espectrometria de Massas (CG-EM). Os extratos foram obtidos através de diferentes solventes (etanol, metanol, hexano, acetona, diclorometano, acetato de etila e água destilada). A atividade antibacteriana foi realizada segundo a técnica de microdiluição em caldo. As análises de CG-EM resultaram na identificação de 15 constituintes principais, todos terpenos, representando 63,88 % do total de óleo essencial. Os compostos majoritários identificados foram Germacreno-D (20,77 %), a-Panasinseno (14,40 %) e b-Selineno (11,68 %). O óleo essencial apresentou atividade antibacteriana frente a 5 sorotipos de Salmonella enterica, com CIM e CBM variando de 7000 a 437 µg.mL-1. Já os extratos variam a CIM e CBM de 200 a 25 mg.mL-1, sendo eficazes para a maioria dos sorotipos de S. enterica, com exceção do extrato aquoso. Os resultados sugerem que o óleo essencial e os extratos das folhas de Z. caribaeum representam uma alternativa para o controle de S. enterica, no setor avícola, refletindo uma nova perspectiva para estudos com produtos naturais.
SUMMARY The present study aimed to identify and quantify the components of the essential oil of Zanthoxylum caribaeum and to evaluate the antimicrobial potential of different plant extracts and the essential oil of this plant against different serotypes of Salmonella enterica, which is of greater occurrence and isolated in the western region of Paraná, Brazil. The extraction of the essential oil was performed using Clevenger apparatus and the chemical composition was determined by Gas Chromatography coupled to Mass Spectrometry (GC-MS). The extracts were obtained through different solvents (ethanol, methanol, hexane, acetone, dichloromethane, ethyl acetate and distilled water). The antibacterial activity was carried out according to the broth microdilution technique. The GC-MS analysis resulted in the identification of 15 main components, all terpenes, representing 63.88% of the total essential oil. The major compounds identified were Germacrene-D (20.77%), a-Panasinsene (14.40 %) and b-Selinene (11.68 %). The essential oil presented antibacterial activity against 5 serotypes of Salmonella enterica, with MIC and MBC ranging from 7000 to 437 μg.mL-1. While MIC and MBC from the range from 200 to 25 mg.mL-1, being effective to most serotypes of S. enterica, with the exception of the aqueous extract. The results suggest that the essential oil and leaf extracts of Z. caribaeum represent an alternative for the control of S. enterica in the poultry sector, in this way reflecting a new perspective for studies with natural products.

Temporal triangular alopecia, also referred as congenital triangular alopecia, is an uncommon dermatosis of unknown etiology. It is characterized by a non-scarring, circumscribed alopecia often located unilaterally in the frontotemporal region. It usually emerges at ages 2-9 years. Alopecia areata is the main differential diagnosis, especially in atypical cases. Dermoscopy is a noninvasive procedure that helps distinguish temporal triangular alopecia from aloepecia areata. Such procedure prevents invasive diagnostic methods as well as ineffective treatments.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
