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.

Resumo Fundamento: A análise de indicadores como taxa de readmissão hospitalar é crucial para aprimorar a qualidade dos serviços e gestão em processos hospitalares. Objetivo: Identificar as variáveis correlacionadas a readmissão hospitalar até 30 dias após cirurgia de revascularização miocárdica (CRM). Métodos: Estudo de coorte transversal no banco de dados Registro Paulista de Cirurgia Cardiovascular II (REPLICCAR II)(N=3.392), de junho de 2017 a junho de 2019. Avaliaram-se retrospectivamente 150 pacientes para identificar os fatores correlacionados a readmissão hospitalar até 30 dias após-CRM via regressão logística univariada e multivariada. As análises foram realizadas no software R, com significância de 0,05 e intervalos de confiança de 95%. Resultados: Cento e cinquenta pacientes foram readmitidos até 30 dias após a alta hospitalar de CRM (150/3.392, 4,42%) principalmente por infecções (mediastinite, ferida operatória e sepse) totalizando 52 casos (52/150, 34,66%), outras causas foram: complicações cirúrgicas (14/150, 9,33%) e pneumonia (13/150, 8,66%). Os preditores de readmissão identificados foram: O modelo de regressão multivariada apontou intercepto (OR: 1,098, p<0,00001), apneia do sono (OR: 1,117, p=0,0165), arritmia cardíaca (OR: 1,040, p=0,0712) e uso de balão intra-aórtico (OR: 1,068, p=0,0021) como preditores do desfecho, com uma AUC de 0,70. Conclusão: 4,42% dos pacientes foram readmitidos pós-CRM, principalmente por infecções.

Abstract Background: The analysis of indicators such as hospital readmission rates is crucial for improving the quality of services and management of hospital processes. Objectives: To identify the variables correlated with hospital readmission up to 30 days following coronary artery bypass grafting (CABG). Methods: Cross-sectional cohort study by REPLICCAR II database (N=3,392) from June 2017 to June 2019. Retrospectively, 150 patients were analyzed to identify factors associated with hospital readmission within 30 days post-CABG using univariate and multivariate logistic regression. Analysis was conducted using software R, with a significance level of 0.05 and 95% confidence intervals. Results: Out of 3,392 patients, 150 (4,42%0 were readmitted within 30 days post-discharge from CABG primarily due to infections (mediastinitis, surgical wounds, and sepsis) accounting for 52 cases (34.66%). Other causes included surgical complications (14/150, 9.33%) and pneumonia (13/150, 8.66%). The multivariate regression model identified an intercept (OR: 1.098, p<0.00001), sleep apnea (OR: 1.117, p=0.0165), cardiac arrhythmia (OR: 1.040, p=0.0712), and intra-aortic balloon pump use (OR: 1.068, p=0.0021) as predictors of the outcome, with an AUC of 0.70. Conclusion: 4.42% of patients were readmitted post-CABG, mainly due to infections. Factors such as sleep apnea (OR: 1.117, p=0.0165), cardiac arrhythmia (OR: 1.040, p=0.0712), and intra-aortic balloon pump use (OR: 1.068, p=0.0021) were predictors of readmission, with moderate risk discrimination (AUC: 0.70).

Abstract This study aims to refine orthogonal cutting analysis using numerical methodology of limit analysis, focusing on predicting cutting forces and contact stresses more accurately. Unlike prior models, it incorporates frictional dissipation and considers sticking or sliding as part of the solution. It is shown that shear stress in sticking contact cannot be equated to shear yield stress, as typically imposed, leading to stress overestimation. The workpiece is treated as a deformable body, discretized with finite elements, while the tool is rigid. Interaction between them follows contact conditions in normal and tangential directions. Inputs include cutting conditions, friction coefficient, and material properties. Results encompass cutting forces, velocity and stress fields, and shear regions. Discrepancy between the shear angle predicted by Merchant and those ones obtained numerically is discussed. Finally, results are compared with experimental data found in literature. This approach provides a more accurate cutting model for determining cutting forces and contact stresses, which is crucial for estimating tool wear and life. accurately models solution imposed overestimation body elements rigid directions coefficient properties fields regions discussed Finally literature life

ABSTRACT: The study of fossil and subfossil birds in Brazil is still in its early stages despite its relatively abundant material. The remains are represented by bones, feathers, mummified specimens, eggs, coprolites, pellets, and tracks found in all Regions of the country starting in the 1830s. They are known from the Early Cretaceous to the latest Holocene, albeit several temporal gaps exist, and the most expressive diversity and quantity are concentrated in a few but important sites. Our survey and review of the literature and some previously unpublished specimens resulted in a list of 670 records demonstrating that the country’s known past avifaunas are essentially modern and rely mostly on provisional determination methods. Despite this, 15 extinct genera and 20 extinct species were newly described, demonstrating this field’s potential. The proper study of numerous long-stored materials from both paleontological and archeological contexts and eventual new remains can contribute significantly to our understanding of avian evolution and their taxonomic diversity throughout time, besides furnishing paleobiogeographic and paleoenvironmental information.

Resumo Aves domésticas, como Gallus gallus, Meleagris gallopavo, Anser anser e Numida meleagris, são amplamente distribuídas pelo mundo e mantêm contato com humanos e outras espécies animais consideradas reservatórios tanto da Leishmaniose Visceral (LV) quanto da Leishmaniose Tegumentar Americana (LTA), incluindo-se cães e gatos, canídeos silvestres, marsupiais; e animais sinantrópicos, como roedores e quirópteros. Portanto, este estudo teve como objetivo detectar a presença de anticorpos anti-Leishmania spp. em aves de uma área rural do município de Santa Maria, sul do Brasil. De maio a dezembro de 2022, foram coletadas 262 amostras de sangue de 244 galinhas, 8 perus, 7 pintadas e 3 gansos, distribuídas em 27 propriedades rurais de 6 distritos. Todos os locais visitados apresentaram aves positivas para a presença de Leishmania spp. Assim, infere-se que o contato com esse protozoário pode induzir a produção de anticorpos, sugerindo que esses animais possam ser utilizados como sentinelas para a circulação desse agente. Além disso, o sangue desses animais é uma fonte de alimento preferencial para insetos da subfamília Phlebotominae, que podem ser utilizados como bioindicadores da presença desses flebotomíneos. domésticas gallus gallopavo meleagris LV (LV LTA, LTA , (LTA) incluindose incluindo se gatos silvestres marsupiais sinantrópicos quirópteros Portanto antiLeishmania anti spp Maria Brasil 2022 26 24 galinhas perus gansos 2 distritos Assim inferese infere agente disso Phlebotominae flebotomíneos (LTA 202 20
Abstract Domestic birds such as Gallus gallus, Meleagris gallopavo, Anser anser and Numida meleagris are widely distributed throughout the world and maintain contact with humans and other animal species considered reservoirs of both Visceral Leishmaniasis (VL) and American Tegumentary Leishmaniasis (ATL), including dogs and cats; wild canids, marsupials; and synanthropic animals such as rodents and chiroptera. Therefore, this study aimed to detect the presence of anti-Leishmania spp. antibodies in birds from a rural area of the municipality of Santa Maria, southern Brazil. From May to December 2022, 262 blood samples were collected from 244 chickens, 8 turkeys, 7 guinea fowl and 3 geese, distributed in 27 rural properties in 6 districts. All the sites visited presented positive birds for the presence of Leishmania spp. Thus, it is inferred that, contact with this protozoan can induce the production of antibodies, suggesting that these animals can be used as sentinels for the circulation of this agent. In addition, the blood of these animals is a preferred food source for insects of the subfamily Phlebotominae, which can be used them as bioindicators of the presence of these phlebotomes. gallus gallopavo VL (VL ATL, ATL , (ATL) cats canids marsupials chiroptera Therefore antiLeishmania anti spp Maria Brazil 2022 26 24 chickens turkeys geese 2 districts Thus agent addition Phlebotominae phlebotomes (ATL 202 20

ABSTRACT Brazil is home to many mountain ranges which harbor diverse avifauna. However, studies on the altitudinal distribution of Brazilian birds are still few and many have never been published, hampering both the dissemination of basic information and conservation actions. Here we present a critical review of ornithological studies undertaken in Brazilian mountain ranges, and propose a classification of geographic scope, altitudinal gradient, and methodology. Since 1922, 184 ornithological studies included altitude in some way in Brazil, encompassing a variety of research topics and species. About a quarter of these studies were never published in peer-reviewed journals, and 39% do not provide basic data on elevation nor link the bird species with sampling plots, thus limiting their applicability. The majority of studies are concentrated (83%) in southern and southeastern Brazil, especially in the Serra do Mar range, and so most data are associated with the Atlantic Forest. Gaps remain in other regions, such as Amazonia (Pantepui region). Most studies either did not sample the entire elevation gradient, were not standardized, lacked explicit hypothesis, or did not account for a seasonal sampling embracing the four seasons of the year, so interpretation of the observed patterns remains difficult. With this compilation, we organize the available information and point to future altitudinal research on birds, in addition to highlighting the importance of preserving habitats along altitudinal gradients in the mountainous regions in Brazil. avifauna However actions scope gradient methodology 1922 18 peerreviewed peer reviewed journals 39 plots applicability 83% 83 (83% range Forest Pantepui region. region . region) standardized hypothesis year difficult compilation 192 1 3 8 (83 19 (8 (

Resumo Fundamento A Doença de Chagas (DC) é uma causa importante de transplante cardíaco (TC). O principal obstáculo é a reativação da DC (RDC), normalmente associada a altas doses de imunossupressores. Estudos anteriores sugeriram uma associação do micofenolato de mofetila com aumento na RDC. No entanto, preditores de mortalidade são desconhecidos. Objetivos Identificar os fatores de risco de mortalidade em pacientes com DC após o TC e o impacto do regime antiproliferativo sobre a sobrevida. Métodos Estudo retrospectivo com pacientes chagásicos submetidos ao TC entre janeiro de 2004 e setembro de 2020, em protocolo de imunossupressão que priorizava o uso de azatioprina e sua mudança para micofenolato de mofetila em caso de rejeição. Realizamos regressão univariada para identificar preditores de mortalidade e comparamos sobrevida, rejeição, e evidência RDC entre os pacientes que usavam azatioprina, micofenolato de mofetila, e aqueles que mudaram de azatioprina para micofenolato (grupo “Mudança”) após a alta. Um valor de p<0,05 foi considerado estatisticamente significativo. Resultados Foram incluídos 85 pacientes, 54,1% homens, idade mediana 49 (39-57) anos, e 91,8% com prioridade na lista de espera. Dezenove (22,4%) usavam azatioprina, 37 (43,5%) micofenolato de mofetila, e 29 (34,1%) trocaram a terapia; a sobrevida não foi diferente entre os grupos, 2,9 (1,6-5,0) x 2,9 (1,8-4,8) x 4,2 (2,0-5,0) anos, respectivamente; p=0,4. Não houve diferença na taxa de rejeição (42%, 73% e 59% respectivamente; p=0,08) ou de RDC (T. cruzi positiva na biópsia endomiocárdica 5% x 11% x 7%; p=0,7; uso benzonidazol 58% x 65% x 69%; p=0,8; PCR positiva para T. cruzi 20% x 68% x 42% respectivamente; p=0,1). Conclusões Este estudo retrospectivo com pacientes com DC e TC não mostrou diferença na sobrevida entre os diferentes regimes antiproliferativos. O uso de micofenolato de mofetila não foi associado com taxas significativamente mais altas de RDC ou rejeição do enxerto nesta coorte. Novos ensaios randomizados são necessários para abordar essa questão. (DC TC. .

Abstract Background Chagas’ disease (CD) is an important cause of heart transplantation (HT). The main obstacle is Chagas’ disease reactivation (CDR), usually associated to high doses of immunosuppressants. Previous studies have suggested an association of mycophenolate mofetil with increased CDR. However, mortality predictors are unknown. Objectives To identify mortality risk factors in heart transplant patients with CD and the impact of antiproliferative regimen on survival. Methods Retrospective study with CD patients who underwent HT between January 2004 and September 2020, under immunosuppression protocol that prioritized azathioprine and change to mycophenolate mofetil in case of rejection. We performed univariate regression to identify mortality predictors; and compared survival, rejection and evidence of CDR between who received azathioprine, mycophenolate mofetil and those who changed from azathioprine to mycophenolate mofetil after discharge (“Change” group). A p-value < 0.05 was considered statistically significant. Results Eighty-five patients were included, 54.1% men, median age 49 (39-57) years, and 91.8% were given priority in waiting list. Nineteen (22.4%) used azathioprine, 37 (43.5%) mycophenolate mofetil and 29 (34.1%) switched therapy; survival was not different between groups, 2.9 (1.6-5.0) x 2.9 (1.8-4.8) x 4.2 (2.0-5.0) years, respectively; p=0.4. There was no difference in rejection (42%, 73% and 59% respectively; p=0.08) or in CDR (T. cruzi positive by endomyocardial biopsy 5% x 11% x 7%; p=0.7; benznidazole use 58% x 65% x 69%; p=0.8; positive PCR for T. cruzi 20% x 68% x 42% respectively; p=0.1) rates. Conclusions This retrospective study did not show difference in survival in heart transplant patients with CD receiving different antiproliferative regimens. Mycophenolate mofetil was not associated with statistically higher rates of CDR or graft rejection in this cohort. New randomized clinical trials are necessary to address this issue. Chagas (CD HT. .

Abstract The Black Skimmer (Rynchops niger) and the Large-billed Tern (Phaetusa simplex) are two migratory waterbirds that breed simultaneously on many river beaches in South America. Both are polytypic taxa with little information about the distribution and nonbreeding (“wintering”) areas. Based on data from the literature, citizen science websites, fieldwork, and specimens housed in natural history museums, we revised the distribution of some of the main breeding colonies in South America, comparing it with continental rainy cycles to identify generalities about the role of precipitation seasonality on the defining intratropical migration routes of these species. Our data suggest that the seasonal precipitation cycle of South America directly influences the reproductive timing and distribution of both species, which is largely circumscribed by South America’s rivers. After breeding on sandy beaches during the dry season, both species disperse in small groups or even individually - not in large flocks as seen in breeding areas - making it difficult to find general migration patterns during the rainy season. Nonetheless, individuals of both species tend to follow the course of the largest rivers of the continent and even alternative routes to disperse into several areas throughout South America during the nonbreeding season.

ABSTRACT Birds’ seasonal altitudinal movements in Brazil are poorly understood. The main source of information and has fostered interest since the 1980s. However, most of the available information is anecdotal, sources are repeatedly cited, and the information provided is quite superficial and speculative. Through bibliographic searches, we found 107 studies, 83 (77%) of which we consider valid, and only 63 (59%) were peer-reviewed. Most studies were carried out in southern and southeastern Brazil. Only 11 studies explicitly addressed seasonal altitudinal movements. Surprisingly, none of the studies simultaneously comprised a full year of study, standardized sampling methods, and encompassed the entire altitudinal range through which the birds might have moved. As a consequence, the quality of the data is questionable, and the expression “altitudinal migration” is unlikely to be accurate and has never been unequivocally demonstrated for birds in Brazil. Mention of “altitudinal migration” was found for 68 bird species, but these must be more clearly defined and appropriately tested.

Objective: Positron emission tomography (PET) allows in vivo evaluation of molecular targets in neurodegenerative diseases, such as Alzheimer’s disease. Mild cognitive impairment is an intermediate stage between normal cognition and Alzheimer-type dementia. In vivo fibrillar amyloid-beta can be detected in PET using [11C]-labeled Pittsburgh compound B (11C-PiB). In contrast, [18F]fluoro-2-deoxy-d-glucose (18F-FDG) is a neurodegeneration biomarker used to evaluate cerebral glucose metabolism, indicating neuronal injury and synaptic dysfunction. In addition, early cerebral uptake of amyloid-PET tracers can determine regional cerebral blood flow. The present study compared early-phase 11C-PiB and 18F-FDG in older adults without cognitive impairment, amnestic mild cognitive impairment, and clinical diagnosis of probable Alzheimer’s disease. Methods: We selected 90 older adults, clinically classified as healthy controls, with amnestic mild cognitive impairment, or with probable Alzheimer’s disease, who underwent an 18F-FDG PET, early-phase 11C-PiB PET and magnetic resonance imaging. All participants were also classified as amyloid-positive or -negative in late-phase 11C-PiB. The data were analyzed using statistical parametric mapping. Results: We found that the probable Alzheimer’s disease and amnestic mild cognitive impairment group had lower early-phase 11C-PiB uptake in limbic structures than 18F-FDG uptake. The images showed significant interactions between amyloid-beta status (negative or positive). However, early-phase 11C-PiB appears to provide different information from 18F-FDG about neurodegeneration. Conclusions: Our study suggests that early-phase 11C-PiB uptake correlates with 18F-FDG, irrespective of the particular amyloid-beta status. In addition, we observed distinct regional distribution patterns between both biomarkers, reinforcing the need for more robust studies to investigate the real clinical value of early-phase amyloid-PET imaging.

Resumo As coleções científicas constituem uma fonte valiosa para contribuições à pesquisa científica e para a formação de recursos humanos em sistemática, mas também em outras áreas do conhecimento biológico. Nesta contribuição, pretendemos discutir esses avanços nas coleções e o papel desempenhado pela FAPESP no seu patrocínio, bem como um panorama geral das coleções zoológicas do estado de São Paulo. Também pretendemos enfatizar a importância das coleções zoológicas e a necessidade de apoio logístico e financeiro contínuo de instituições e agências de pesquisa para manter e desenvolver esses repositórios únicos de biodiversidade. Ao longo de 1980 até os dias atuais, a FAPESP apoiou 118 projetos de pesquisa focados em diversas áreas da zoologia, direta ou indiretamente associados a coleções. Há um crescimento constante no número de projetos, e o apoio financeiro da FAPESP por meio do Programa Biota foi fundamental para o avanço do nosso conhecimento sobre a biodiversidade no Brasil. Paralelamente aos avanços científicos, mas não menos importante, este apoio permitiu aos curadores aumentar o número de exemplares, e organizá-los, mantê-los e digitalizá-los nestas valiosas e insubstituíveis coleções. Em relação à falta de novos taxonomistas, é fundamental que a FAPESP e as universidades paulistas estimulem a formação de novos acadêmicos em grupos zoológicos onde os especialistas são raros. Considerando o investimento realizado pela FAPESP, é de suma importância que as instituições beneficiadas com esses recursos tenham maior responsabilidade na salvaguarda desses acervos, devendo considerar a inclusão de recursos em seus orçamentos para obtenção de certificados de segurança, garantindo sua permanência por muitas gerações. As coleções zoológicas são patrimônio da humanidade, e são essenciais não apenas para o aprimoramento do nosso conhecimento sobre a biodiversidade, mas também com aplicações diretas, entre outros serviços prestados por esses recursos biológicos. É importante que as instituições de pesquisa e ensino paulistas que abrigam exemplares sob seus cuidados passem a valorizar mais esse importante patrimônio e essa herança, pois essas coleções representam o testemunho mais valioso de nossa impressionante biodiversidade, registros do nosso passado e janelas para o nosso futuro, essenciais à nossa soberania acadêmica, científica, cultural e social. sistemática biológico contribuição patrocínio Paulo 198 atuais 11 zoologia Brasil científicos organizálos, organizálos organizá los, los organizá-los mantêlos mantê digitalizálos digitalizá taxonomistas raros acervos segurança gerações humanidade diretas biológicos herança futuro acadêmica social 19 1
Abstract Scientific collections constitute a valuable source for contributions to scientific research and the training of human resources in systematics, but also other areas of biological knowledge. In this contribution, we intend to discuss these advancements in collections and the role played by FAPESP in sponsoring them, as well as a general overview of the zoological collections in São Paulo state. We also aim to stress the importance of zoological collections and the need for continuous logistic and financial support from institutions and research agencies to maintain and develop these unique repositories of biodiversity. From 1980 to the present, FAPESP supported 118 research projects focused on several areas of zoology that are directly or indirectly associated with collections. There is a constant growth in the number of projects, and the financial support provided by FAPESP through the Biota Program was paramount for the advancement of our knowledge of biodiversity in Brazil. Parallel to the scientific advances, but not less important, this support allowed curators to increase the number of specimens, and to organize, maintain and digitize them in these valuable and irreplaceable collections. Regarding the lack of new taxonomists, it is essential that FAPESP and universities in São Paulo encourage the formation of new academics in zoological groups where specialists are rare. Considering the investment provided by FAPESP, it is quite important that the institutions that benefited from these resources took greater responsibility to safeguard these collections, and they should consider including resources on their budgets to obtain safety certificates, ensuring their permanence for many generations to come. Zoological collections are a heritage of humanity and are essential not only for the improvement of our knowledge of biodiversity but also with direct applications, among other services provided by these biological resources. It is important that research and teaching institutions in São Paulo that house specimens under their care start to value more this important patrimony and this heritage, as these collections represent the most valuable testimony of our impressive biodiversity, records of our past, and windows to our future, essential to our academic, scientific, cultural and social sovereignty. systematics contribution state 198 present 11 Brazil advances organize taxonomists rare certificates come applications past future academic sovereignty 19 1

ABSTRACT Although stable isotopes have been increasingly used in ornithology since 1980 in many places, Brazil has been slow in adopting this methodology, especially when it comes to terrestrial birds. The most common elements in bird ecology studies are carbon, nitrogen, hydrogen, and oxygen stable isotopes, which provide information on diet, trophic interactions, habitat use, migration, geographic patterns, and physiology. It is important that Brazilian ornithologists become aware of the potential of stable isotope analysis in ecological studies, and the shortcomings of this tool. The use of stable isotopes to study bird ecology has great potential in Brazil, since many ecological questions about Neotropical birds can be addressed by it (e.g., resource and habitat use, migratory routes, isotopic niches, anthropogenic impacts, individual specialization). Brazilian museums and other Natural History collections can provide samples to study long-term temporal dynamics in bird ecology. Additionally, the integration of avian tissue sample information into a database may increase the collaboration among researchers and promote sample reuse in a variety of studies. All biomes in Brazil have been under pressure from anthropogenic impacts (e.g., land-use change, habitat loss, fragmentation, intensive agriculture), affecting several taxa, including terrestrial birds. Considering the negative effects of human expansion over natural areas and that stable isotopes provide useful ecological information, ornithologists in Brazil should increase their use of this tool in the future.

ABSTRACT Altitudinal migration in birds comprises seasonal movements between breeding and non-breeding areas in mountainous regions, attributed to biotic and abiotic factors. Different authors have suggested the existence of altitudinal migration between high and low areas of the mountains of the Atlantic Forest, with movement from high to low during the winter when birds would be fleeing the cold and in search of food, but there is no documented evidence. Through recaptures of understory birds, we investigated possible altitudinal migration in a region of the Atlantic Forest in Southeast Brazil. Twenty mist-nets were set at four locations between 15 and 729 m a.s.l. during 143 days of field work, distributed over 54 months and covering all seasons of the year. A total of 1946 birds (98 species) were captured/banded with 558 being recaptured (28.6%; 45 species). However, only 42 of the recaptures were at a different elevation. Most of the movements were of short distances and performed only once by birds, showing no seasonal pattern. These movements may be better interpreted as daily movements undertaken by birds of mixed-species flocks looking for food or moving around their respective home-ranges. Our results show that mist-nets may not be an effective tool in detecting altitudinal movements of birds and that other methods should be evaluated for this purpose.
