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 The harsh Antarctic climate limits soil formation and the development of terrestrial ecosystems, with most biological activity concentrated in the short summer season in ice-free areas. There, penguins play a crucial role in nutrient transport from marine to terrestrial environments, significantly impacting soil properties through guano deposition. This study focuses on characterizing the ornithogenic soils of Half Moon Island in Maritime Antarctica, examining how lithology, vegetation, and geomorphology influence their formation and distribution. Fieldwork conducted during the 2014/2015 austral summer included excavating and sampling 21 soil profiles. Soils were analyzed for physical and chemical properties and classified. Half Moon Island’s soils are predominantly Cryosols and Leptosols, characterized by little development, high gravel content (skeletic), and significant cryoturbation. High variability in soil chemical properties was observed, with principal component analysis highlighting distinct clusters based on landscape position, geology, vegetation and ornithogenic influence. The findings underscore the diverse pedoenvironments of Half Moon Island, shaped by past and present ornithogenic activity and post-glacial geomorphological processes. This research highlights the soil variability in Antarctic environments and the significant ecological importance of seabird colonies on small, isolated islands. ecosystems icefree ice free areas There deposition Antarctica lithology distribution 20142015 2014 2015 2014/201 2 profiles classified Islands s Leptosols skeletic, skeletic , (skeletic) cryoturbation observed position geology postglacial post glacial processes small islands 2014201 201 2014/20 (skeletic 201420 20 2014/2 20142 2014/

Abstract Areas of high concentration of seal carcasses have been observed in localized areas of James Ross Island, Antarctica. Such carcasses show an unusual vegetation development, in a semi-arid area with bare soils under intense winds, high salinity and sandy texture. We investigated carcasses of seals around a lake in James Ross Island, with four different stages of decomposition, with three replicates: Seal (S01), with recently mummified carcasses; S02, with partially degraded carcasses; S03, with broken carcasses with partially degraded exposed bones, and S04, with completely broken, scattered skeletons. The vegetation showed a maximum degree of development in carcasses at stages S02 and S03, with the environment between the skin and the skeleton as the preferred place for vegetation establishment. The chemical alteration was greater with increasing carcass decomposition but reduced with the spreading and final decomposition of the bones, with anomalous values observed only in the vicinity of the carcasses. It is concluded that the presence of carcasses of seals, concentrated in wet places, even in a semi-desert climate, represent important oases of nutrients, with a combination of physical and chemical effects throughout the decomposition process that favor plant establishment and succession.

Abstract Active layer and permafrost are important indicators of climate changes in periglacial areas of Antarctica, and the soil thermal regime of Maritime Antarctica is sensitive to the current warming trend. This research aimed to characterize the active layer thermal regime of a patterned ground located at an upper marine terrace in Half Moon Island, during 2015-2018. Temperature and moisture sensors were installed at different soil depths, combined with air temperature, collecting hourly data. Statistical analysis was applied to describe the soil thermal regime and estimate active layer thickness. The thermal regime of the studied soil was typical of periglacial environment, with high variability in temperature and water content in the summer, resulting in frequent freeze-thaw cycles. We detected dominant freezing conditions, whereas soil temperatures increased, and the period of high soil moisture content lasted longer over the years. Active layer thickness varied between the years, reaching a maximum depth in 2018. Permafrost degradation affects soil drainage and triggers erosion in the upper marine terrace, where permafrost occurrence is unlikely. Longer monitoring periods are necessary for a detailed understanding on how current climatic and geomorphic conditions affect the unstable permafrost of low-lying areas of Antarctica (marine terraces). trend Island 20152018. 20152018 2015 2018 2015-2018 depths data environment summer freezethaw freeze thaw cycles increased years unlikely lowlying low lying terraces. terraces . terraces) 2015201 201 2015-201 201520 20 2015-20 20152 2 2015-2 2015-

Abstract Maritime Antarctica is one of the major terrestrial ecosystems dominated by lichens and mosses, which represent important ecological indicators. Thus, we aimed to evaluate the changes in associated communities of mosses-lichens diversity and coverage along a pedoenvironmental gradient on Half Moon Island, Maritime Antarctica. We focused on how patterns in associated communities of mosses-lichens species diversity (richness, species composition and beta diversity) and coverage are associated with soil properties using plant inventory data from 174 plots across 14 contrasting pedoenvironments. The results clearly show marked differences in soil properties along the pedoenvironmental gradient, which determine variations in species composition, richness and coverage. We presumed that these variations are common in Maritime Antarctica owing to varying periglacial processes, weathering degree, parent material and biological influence (especially by penguins and other birds). The community species richness and coverage along the pedoenvironmental gradient differ, nevertheless share common species present in most pedoenvironments, despite differences in coverage. We assume that most of the pedoenvironments are habitats to rare species that occur only under specific soil conditions, additionally promotes high β-diversity between pedoenvironments and low species similarity.

Abstract The Antarctic Peninsula has experienced some of the most accelerated warming worldwide, resulting in the retreat of glaciers and creation of new areas for plant development. Information regarding the plant dispersal processes to these new niches is scarce in Antarctica, despite birds being important vectors elsewhere. Many bird pellets (with feed remains such as bones and feathers) are generated annually in Antarctica, which are light and easily transported by the wind and include vegetation that is accidentally or purposely swallowed. The aim of this study was to analyze the presence of plant fragments within skua (Stercorarius/Catharacta spp.) pellets collected from two sampling areas in the Maritime Antarctic: Stinker Point (Elephant Island, 17 samples) and Byers Peninsula (Livingston Island, 60 samples), in the South Shetland Archipelago, during the austral summers of 2018 and 2020. In both study areas, five species of Bryophyta were found that were associated with the pellets and viable in germination tests in a humid chamber. The ingestion of Bryophyta for the skuas contribute to the dispersion of different moss species, including to areas recently exposed by the ice retreat. This is the first demonstration that skua pellets effectively act in the dispersion of Antarctic mosses.

Abstract The geomorphic dynamics on ice-free areas are crucial for understanding soil formation, vegetation and landscape stability in maritime Antarctic. We aimed to describe the soil formation on different landforms, following the Holocene glacial retreat at Stinker Point. Twenty profiles were sampled and classified, grouped into three landforms units: middle platforms and scarps, till/glacial deposits and present/Holocene raised beaches. Soil chemical and physical attributes were determined, and the vegetation type identified and quantified. Soils from till and glacial deposits can be separated by the age of exposure: older soils are stony, skeletic; and recently exposed till has soils with moderate depth, alkaline reaction and very high base saturation. Soils at the middle platforms are shallow, coarse-grained, skeletic, with abundant vegetation. Soils from the present-day beaches are alkaline, very coarse with no horizon differentiation, whereas soils on Holocene beaches are acid and nutrient-rich due to past or present-day influence of fauna. Soils from Stinker Point are generally shallow, skeletic and strongly related to the landforms and biogenic influences. Compared with other islands of the South Shetlands, in Elephant Island soil development is less pronounced, being this mainly attributed to the metamorphic nature of parent material, with greater resistance to weathering.

Abstract Ice-free areas of Antarctica represent an important study region that helps us understand how human activity affects plant communities and soil properties. The goal of this study was to determine the changes in plant composition and soil properties around a whale bone skeleton (WB) near Ferraz Station, King George Island, Antarctica from 1972 to 2020 (48 years). The WB was assembled in 1972 by Jacques-Yves Cousteau and his team. It is located in a large moss field and visited by many tourists. We studied the plant composition and development based on historical and recent photographs and phytosociological studies from 1986 to 2020. The soil was sampled in February 2009 to determine general properties. The results showed that human activity surrounding the WB directly affected the plant community composition and soil properties. The Syntrichia cushions were positively affected by the calcium deposits from bone dissolution. The principal component analysis revealed that mineralization of the bones increased soil nutrient assembly. A strong phosphatization process was observed in the WB area, similar to that in ornithogenic soils. The WB on the marine terrace enhanced soil fertility and changed the plant community.

Abstract The aim of this research was to evaluate the physical attributes of Cambisol in apple (Malus domestica Borkh. cv. Gala) orchard under different weed management systems in the state of Santa Catarina (SC), Brazil. The treatments were as follows: control (no weed management), chemical desiccation and mowing. We took samples of undisturbed soil at depths of 0-5, 5-10, 10-15 and 15-20 cm. We evaluated hydraulic conductivity (HC); bulk density (BD); soil penetration resistance (Pr); total porosity (TP), macropores (MaP), micropores (MiP); soil aggregation indices such as arithmetic and geometric mean diameter of air-dried and water-stable aggregates (AMDad, AMDws, GMDad, GMDws, respectively); aggregate stability index (ASIAMD and ASIGMD) and volumetric water content (VWC). We also carried out principal component analysis (PCA) with the data. The mowing or desiccation treatments increased BD at the 15-20 cm depth compared to control. The mowing treatment had the highest ASIGMD while desiccation contributed to the lowest ASIGMD. The desiccation treatment decreased AMDws (0-10 cm), ASIAMD (0-5 cm) GMDws (5-10 cm) and reduced HC by 26% and 22%, respectively, compared to the mowing and control treatments. Through PCA we were able to separate the three treatments. The mowing treatment was correlated with HC, VWC at pressure of 600 kPa and ASIGMD; desiccation was correlated with BD and Pr; and control with ASIAMD, MaP and TP.
Resumo O objetivo do trabalho foi avaliar os atributos físicos de Cambissolo em pomar de macieira (Malus domestica Borkh. cv. Gala) em Santa Catarina, Brasil, submetido a diferentes manejos das plantas espontâneas. Os tratamentos avaliados foram: testemunha (sem manejo das espontâneas), dessecação química e roçada. Foram coletadas amostras indeformadas de solo nas profundidades de 0-5, 5-10, 10-15 e 15-20 cm, nas quais foram avaliadas a condutividade hidráulica (CH); densidade do solo (Ds); resistência do solo à penetração (Rp); porosidade total (PT), macroporos (MaP), microporos (MiP); índices de agregação do solo, sendo o diâmetro médio aritmético e geométrico dos agregados secos ao ar e estáveis em água (DMAsa, DMAea, DMGsa, DMGea, respectivamente); índice de estabilidade de agregados (IEADMA e IEADMG) e umidade volumétrica (UV). Também realizou-se uma análise de componentes principais (ACP) com os dados obtidos. O manejo com roçada ou dessecação aumentou a Ds (15-20 cm) quando comparado com a testemunha. O tratamento roçada foi responsável por apresentar o maior IEADMG, enquanto a dessecação contribui para o menor IEADMG. O manejo com a dessecação diminuiu o DMAea (0-10 cm), IEADMA (0-5 cm), DMGea (5-10 cm) e reduziu a CH em 26% e 22%, respectivamente, em relação à roçada e testemunha. Por meio da ACP foi possível separar os três tratamentos avaliados, sendo o manejo com a roçada correlacionado com a CH, UV na tensão de 600 kPa e IEADMG; a dessecagem correlacionado com DS e RP; e a testemunha correlacionada com IEADMA, MaP e PT.

ABSTRACT This study evaluated the physical attributes of Humic Cambisol cultivated with onion in a no-tillage system (NTSV) and conventional tillage system (CTS), as compared to a secondary forest. The treatments consisted of the use of cover crops, alone and intercropped in an agroecological onion NTSV for six years, in randomized blocks with five replications: spontaneous vegetation, 100% oats; 100% rye; 100% wild radish; intercropping of wild radish (14%) and rye (86%); and intercropping of wild radish (14%) and oats (86%). We also evaluated an onion cultivation area under CTS for ±38 years and a forest area (secondary forest for ±31 years). Undisturbed soil samples were collected at depths of 0-5, 05-10, 10-15 and 15-20 cm, and the soil density, total porosity, macro and micropores, mean geometric diameter and mean weighted diameter of aggregates, and volumetric moisture were evaluated. The NTSV increased the aggregation indices, total porosity and volumetric moisture in comparison to the CTS and the aggregation indices in relation to the forest area. Alone and intercropped wild radish with oats and rye improved the soil physical attributes as compared to the CTS.
RESUMO Este trabalho avaliou os atributos físicos do solo cultivado com cebola em sistemas plantio direto de hortaliças (SPDH) e preparo convencional (SPC) do solo, comparados à área de floresta secundária. Os tratamentos constituíram-se da utilização de plantas de cobertura, solteiras e consorciadas em SPDH agroecológico de cebola por seis anos, em blocos ao acaso com cinco repetições: vegetação espontânea, 100% aveia; 100% centeio; 100% nabo forrageiro; consórcio de nabo forrageiro (14%) + centeio (86%); consórcio de nabo forrageiro (14%) + aveia (86%). Adicionalmente, foram avaliadas duas áreas, uma sob SPC com cultivo de cebola por ±38 anos e outra de mata (floresta secundária, ±31 anos). Foram coletadas amostras indeformadas de solo nas profundidades de 0-5, 05-10, 10-15 e 15-20 cm, e nestas avaliaram-se a densidade do solo; porosidade total, macro e microporos; diâmetro médio ponderado e geométrico dos agregados, e umidade volumétrica. O SPDH aumentou os índices de agregação, a porosidade total e umidade volumétrica em comparação ao SPC, e equiparou-se aos índices de agregação em relação à área de mata. O nabo solteiro e consorciado com aveia e centeio melhorou os atributos físicos do solo em comparação com o SPC.

ResumoAs pesquisas definidas como estado da arte ou da questão, entre as várias nomenclaturas utilizadas, não constituem, aparentemente, uma preocupação efetiva entre os pesquisadores da Comunicação. A partir de um entendimento de que esta tarefa é não apenas necessária como também urgente, a pesquisa aqui relatada se debruça sobre a produção acadêmica stricto sensu desenvolvida nas duas últimas décadas dentro dos estudos de recepção. Foram analisadas as teses e dissertações produzidas nos Programas de Pós-Graduação em Comunicação no intervalo de 1990 a 2009 com vistas a mapear o cenário teórico metodológico adotado pelos pesquisadores que se dedicaram a compreender esse fenômeno complexo das relações entre “meios e audiências”. Os resultados apontam para um ainda lento crescimento desses estudos e vários desafios teóricos para o enfrentamento da problemática.

Based on the understanding that this work is not only necessary, but also urgent, this research focuses on the stricto sensu academic production about reception studies developed in the past two decades. Thesis and dissertations produced in the Graduate Programs in Communication from 1990 to 2009 were analyzed, aiming to map the theoretical and methodological scenario adopted by researchers who made efforts to understand this complex phenomenon of relations between “Media and audiences”. The results point to a slow growth of these studies and several theoretical challenges as regards facing such theme.

O território dos afetos, denominação genérica sob a qual abarcamos emoções, paixões e sentimentos em suas diversas nuanças, tem sido abordado sob diferentes enfoques epistemológicos ao longo do tempo. Partindo de uma perspectiva fisiológica, passou depois por enfoques metafísicos, indo até o surgimento de olhares mais atentos ao papel das interações sociais no desenvolvimento humano, que compreendem o campo dos afetos no contexto dos processos semiótico-culturais nos quais se constitui o sujeito. No presente artigo buscaremos resgatar as contribuições da abordagem histórico-cultural esboçada por Lev Semenovich Vigotski para o estudo das emoções, a qual estabeleceu marcos importantes em meio aos debates das correntes vigentes no século XX. Situaremos, em seguida, algumas abordagens contemporâneas de orientação sociocultural que se propõem a dar prosseguimento à proposta do autor russo, analisando avanços trazidos por novas pesquisas sobre o tema. Por fim, discutiremos desafios e implicações de uma perspectiva histórica e sociocultural para o estudo dos afetos que atente para a complexidade e a dinamicidade dos fenômenos psicológicos.
The territory of affectivity, the generic category that embraces emotions, passions and feelings in their various nuances, has been approached from different epistemological perspectives over time. From physiological to metaphysical approaches based on the role of social interactions in human development, comprising the field of affect within the context of the semiotic-cultural processes in which the subject constitutes itself. In this article, we present and discuss the contributions of the cultural-historical approach outlined by Lev Semenovich Vygotsky for the study of emotions, which established a milestone amid the explicative tendencies found in debates over the subject in the 20th century. We also discuss some sociocultural contemporary approaches as they build upon the Russian author's proposal, analyzing advances brought by new researches about the topic. Finally, we discuss challenges and implications of a sociocultural and historical perspective to the study of affectivity that takes seriously the complex and dynamic nature of psychological phenomena.

O melhoramento genético da batata é complexo e requer uma grande demanda de tempo e energia. A tecnologia do DNA recombinante, com sua capacidade potencial de isolar e transferir genes a partir de qualquer organismo, permite incorporar nas plantas novos caracteres de interesse agrícola. No entanto, as conseqüências da inserção de determinados genes em relação às características fisiológicas da planta são, muitas vezes desconhecidas. O presente trabalho teve como objetivo avaliar as características fotossintéticas de plantas de batata cultivar Baronesa modificadas geneticamente com genes de resistência a vírus. Para isso, tubérculos de batata cultivar Baronesa e seu respectivo genótipo transformado foram plantados em vasos e mantidos em casa de vegetação. Durante o ciclo de vida das plantas foram avaliados parâmetros da fluorescência das clorofilas, fotossíntese líquida e fotossíntese potencial. As plantas de batata cv. Baronesa transformadas com genes de resistência ao vírus PVY apresentaram maior eficiência fotoquímica máxima e maior taxa de liberação de oxigênio do que plantas da mesma cultivar não modificadas geneticamente, embora tivessem mantido os demais parâmetros de fluorescência das clorofilas e a taxa de fotossíntese líquida iguais.
Potato breeding is difficult and requires a great deal of time and energy. The use of recombinant DNA technology, with its potential capacity of isolating and transferring genes from any organism, allows incorporating in plants new characters of agricultural interest. However, consequences of the incorporation of determined genes on physiological characteristics are sometimes unknown. In this study we evaluated photosynthetic characteristics of potato plants genetically modified with resistance genes to PVY. Potato tubers of cv. Baronesa and its respective transformed genotype were planted in pots and kept in greenhouse. During the plant life cycle, parameters of chlorophyll fluorescence, net photosynthesis and potential photosynthesis were evaluated. Plants transformed with PVY resistant genes showed higher maximum photochemical efficiency and higher oxygen evolution rate, however the parameters of chlorophyll fluorescence and net photosynthesis were the same.

No período de janeiro a julho de 2004, foram realizadas 97 necropsias de suínos que apresentaram subdesenvolvimento, aumento generalizado de linfonodos, palidez ou icterícia de mucosas e, ocasionalmente, problemas respiratórios. As principais lesões macroscópicas encontradas incluíram aumento generalizado de linfonodos, pulmões não colapsados com bordos arredondados e áreas de consolidação, especialmente crânio-ventrais, além de edema de septos interlobulares. Os rins estavam pálidos, aumentados de volume e com pontos brancos que, difusamente distribuídos na superfície, infiltravam em forma de estrias até a zona cortical. Alguns apresentavam pequenos pontos vermelhos, semelhantes a petéquias, difusamente distribuídos no córtex renal. O achado histológico comum foi a presença, em graus variáveis, de infiltrados linfo-histiocitários em linfonodos, pulmões e rins. O teste imuno-histoquímico utilizando anticorpo policlonal anti-circovírus suíno tipo 2 foi positivo em amostras provenientes de 50 (89,2%) entre 56 suínos examinados.
A total of 97 pigs, which had presented wasting, lymphadenomegaly, respiratory distress and pale or icteric mucosa, was necropsied over a 6-month period. Macroscopic lesions were characterized mostly by enlarged lymph nodes, non collapsed and round edged lungs with cranio-ventral areas of consolidation and interlobular edema. Kidneys had increased size, were pale, and presented numerous scattered white spots projecting from surface to the cortical area. Some kidneys also showed small red spots similar to petechial hemorrhage over the cortex. Main microscopic lesions were lympho-histiocytic infiltration in lymph nodes, lungs, and kidneys. Immunohistochemical probing with polyclonal antisera to type II swine circovirus stained positively in 50 out of the 56 cases tested (89.2%).
