Stigmatodon enigmaticus D. R. Couto, Gonella & A. F. Costa 2023, sp. nov.
No full textStigmatodon enigmaticus D.R. Couto, Gonella & A.F. Costa, sp. nov. (Figures 1–2) Stigmatodon enigmaticus differs from S. vexatus by the more numerous leaves (15–25 vs. 10–12 in number), distinctly smaller leaf blade (6–8.5 × 1.5–2.3 cm vs. 13–14 × 2.8–3.7 cm), with acuminate apex (vs. caudate), floral bracts red (vs. green), flowers with diurnal anthesis (vs. nocturnal), greenish-yellow sepals (vs. green), yellow petals (vs. greenish-yellow), and stamens and stigma exceeding the corolla (vs. shorter than the corolla). Type: — BRAZIL. Minas Gerais: Conselheiro Pena, Serra do Padre Ângelo, Serra do Pinh „o, campo rupestre, 1,300 m elevation, 2 May 2021 (flowered in cultivation in November 2021), P . M. Gonella 2965, D. P. Cordeiro, G. A. da Silva, P. R. Bartholomay, J. C. Ribeiro & L. Medeiros (holotype MBML!). Description: — Plant rupicolous, heliophytic, 21–35.5 cm tall when flowering, propagating by basal axillary shoots. Leaves 15–25, forming a utriculiform rosette; sheath ovate to elliptic, 6–8.5 × 4–5.5 cm, purplish to purplishgreen distally, castaneous at the base, densely lepidote on both sides, chartaceous; blade narrowly triangular, 6–8.5 cm long, 1.5–2.3 cm wide at the base, green to dark reddish, densely lepidote on both sides, forming white crossbands on adaxial surface, suberect to spreading-recurved, revolute along the margins (under water stress), apex acuminate. Peduncle suberect or curved at the base, (16-) 23–30 cm long, 1.2–1.8 mm in diameter, green, glabrous; peduncle bracts erect, exceeding the internodes, imbricate, elliptic, apex rounded then acuminate to caudate, 1.7–3 × 1.4 cm, the lower ones subfoliaceous, green, the upper ones red, lepidote on both sides, more sparsely lepidote near the margins, densely white lepidote near the apex. Inflorescence simple, 4–12 cm long, suberect, with apical sterile bracts, 3–7 flowered; main axis slightly geniculate, 2.8–3 mm in diameter, green, glabrous, internodes 5–9(-16) mm; floral bracts suborbicular, apex broadly obtuse, 1.7–2.2 × 1.0– 1.7 cm, ecarinate, secund with the flowers at anthesis, red, exceeded by the sepals, densely lepidote abaxially, adaxially glabrous, coriaceous. Flowers distichous, secund at anthesis, diurnal, 4.0– 5.5 cm long; pedicel green, 4.5–7.2 mm long; sepals elliptic, apex obtuse, 20–23 × 10–11 mm, greenishyellow, ecarinate, glabrous, coriaceous, free; petals linear-oblong, 3.0–3.5 × 0.5–0.8 cm, apex rounded to emarginate, suberect with spreading apex, yellow, glabrous, connate at the base to 0.9–1.5 mm, forming a prevailing tubular corolla; petal appendages 6–7.6 × 2–2.5 mm, spatulate, apex rounded, distally free for 2.5–3.2 mm; stamens exserted for 2–3.8 mm; anthers oblong in outline, 4–5 mm long, obtuse, dorsifixed near the base; filaments complanate, 25–31 mm long, pale yellow, adnate to the petals for 4.3–5 mm; ovary superior, 4.2–5.4 mm long; style 30–35 mm long; stigma convolute blade type (the vriseoid type II), exceeding the corolla for 8–9 mm, green, ca. 1.4 mm in diameter. Capsules unknown. Phenology: —Colected with flowers in October (in situ), and in November and December (in cultivation). Distribution and ecology: — Stigmatodon enigmaticus is a lithophyte on quartzitic rocky outcrops (Fig. 1C) within the Atlantic Forest, in the municipality of Conselheiro Pena, eastern Minas Gerais state, Brazil. So far, the species is only known from the type locality at Serra do Pinh„o (above 1,250 m elevation), part of Serra do Padre Ângelo (Fig. 1A). At the type locality, the species forms a small and sparse population, exposed to full sunlight, growing in crevices or fissures, or directly on bare rock, usually on horizontal or inclined quartzitic rocky outcrops (Fig. 1), surrounded by herbaceous and shrubby vegetation (Fig. 1B, C). The floral characteristics of this species, i.e., floral bracts red, flowers with diurnal anthesis, yellow petals, and stamens and stigma exceeding the corolla (Fig. 1F–H), allows us to suggest that it is possibly pollinated by hummingbirds (Neves et al. 2020), an unusual characteristic for the genus Stigmatodon (its species have nocturnal flowers and bat-pollination). This observation raises new and promising perspectives for evolutionary, morphological, and taxonomic studies in Stigmatodon. Preliminary conservation status: —Critically Endangered (CR): B2ab(iii). Stigmatodon enigmaticus is a microendemic species with an Area of Occupancy (AOO) of 4 km ², found only in Serra do Pinh„o (Fig. 1 A–B). While the rock outcrop where it is found is relatively protected from fires by the irregular topography, the surroundings have been severely transformed in the past decades, from the original matrix of Semideciduous Seasonal Forest to pastures for cattle farming. Fires for pasture renovation are regular in the area, as is the active conversion of the few remnants of secondary forest into pastures, with the use of fire, one of such observed during one of the expeditions to the area in October 2022. Similar criminal fires resulted in a wildfire of great proportions that affected the neighboring Pico do Padre Ângelo in September 2020, affecting many of its endemics (Andrino & Gonella 2021, Kollmann & Gonella 2021, Gonella et al. 2022). The frequent fires in the area facilitated the invasion of the rocky outcrops by alien grass species, such as Melinis minutiflora Beauvois (1812: 54), which can be found on the rocky outcrop that S. enigmaticus inhabits. The area where the species is found is not protected by any sort of Protected Area but should be recognized as a priority for conservation given the exceptional biodiversity and the relevance of the ecosystem services provided by the mountainous relief and native vegetation of Serra do Padre Ângelo, such as water cycle, climate balance, and pollinators, among others. Finally, less than 20 mature individuals could be located in the area, suggesting that the population is relatively small, as is common with microendemic species from the Campos Rupestres (Conceiç„o et al. 2007). Given the aforementioned characteristics and threats, we have preliminarily assessed S. enigmaticus as Critically Endangered based on the categories and criteria of IUCN (2012). Etymology: — This new species was discovered in May 2021, when only sterile specimens were observed, and its vegetative characteristics pointed to Stigmatodon. However, when in flower, its red bracts and yellow sepals and petals, common in Vriesea and so far not reported for Stigmatodon, raised the question of its generic placement. This puzzling combination inspired the epithet, from the Greek aenigma meaning “riddle”, or “enigma”. Additional specimens examined (paratypes): ___ BRAZIL. Minas Gerais: Conselheiro Pena, Serra do Padre Ângelo, Serra do Sossego, campo rupestre, 1,250 m elevation, 15 October 2022, (fl.), D. R . Couto 6625, P. M. Gonella, L. Medeiros, D. Cordeiro & L. Magalhães (R!); ibidem, 1,350 m elevation, 13 May 2022, P . M. Gonella 3521, E. P. Fernandez, G. Crispin, G. A. Queiroz & J. C. Ribeiro (MBML!). Discussion: — Stigmatodon enigmaticus, resembles the small rupicolous species of “ Stigmatodon limae group” (Fig. 1 C), from which it is easily distinguished by its red floral bracts, as well as by the yellow and linear-oblong petals, and the exserted stamens and stigma. Among the species of the S. limae group, this new species is morphologically most similar to S. vexatus, which is endemic to the Pico da Aliança, an emblematic quartzitic mountain distant about 20 km from the type locality of S. enigmaticus, in the neigboring municipality of Alvarenga. Stigmatodon enigmaticus can be distinguished from S. vexatus by its ovate to elliptic leaf sheaths (vs. broadly ovate), which are purplish to purplish-green toward the apex and castaneous at the base (vs. vinaceous brown adaxially), leaf blade with revolute margins (under water stress vs. flat to involute), peduncle longer (up to 30 cm vs. up to 13 cm), larger flowers (4.0– 5.5 cm vs. ca. 3.2 cm), and obovate to elliptic sepals (vs. oblong-elliptic; data on S. vexatus from Leme 2016). For the Stigmatodon limae group, three stigma types have been recognized recently (see Leme et al. 2022a), which are relevant to the Stigmatodon taxonomy: tubo-laciniate type II, observed in S. rosulatulus (Leme 2012: 10) Leme, G.K. Br. & Barfuss (in Barfuss et al. 2016: 58) and S. ilhanus Leme & D.R. Couto (in Leme et al. 2022a: 7); (ii) convolute-blade (the vriseoid type II), observed in S. freicanecanus (Siqueira & Leme, 2006a: 377) D.R.Couto & A.F.Costa (in Couto et al. 2022: 352), S. oliganthus (Baker, 1887: 345) D.R.Couto & A.F.Costa (in Couto et al. 2022: 354), S. vellozicolus (Leme & Siqueira 2006b: 406) D.R.Couto & A.F.Costa (in Couto et al. 2022: 354), S. vexatus and S. enigmaticus; and (iii) convolute-blade type III (stigmadontoid type III), observed in S. andaraiensis (Leme 2012: 16) D.R.Couto & A.F.Costa (in Couto et al. 2022: 352), S. itamarajuensis Leme, D.R. Couto & L. Kollmann (in Leme et al. 2022a: 9), S. limae (Smith 1970: 181) D.R.Couto & A.F.Costa (in Couto et al. 2022: 354), and S. zonatus (Siqueira & Leme 2006a: 374) D.R.Couto & A.F.Costa (in Couto et al. 2022: 354). The floral features of S. enigmaticus, i.e., red bracts and yellow perianth, exserted stamens and stigma, and diurnal anthesis, are unique in the genus Stigmatodon but common in Vriesea (Costa et al. 2014, Neves et al. 2020, Couto et al. 2022). These characteristics, associated with hummingbird pollination syndrome (ornithophily), seem to be the ancestral state among bromeliads, while bat pollination (chiropterophily) originated multiple times in the family as a whole (Aguillar-Rodríguez et al. 2019), as well as in Vriesea (Kessler et al. 2020; Neves et al. 2020), and is supported as an ancestral state in Stigmatodon species (Couto et al. 2022). All the 33 previously known species of Stigmatodon bear chiropterophilous flowers, therefore the floral features of S. enigmaticus could result from the retention of the ancestral state or a reversion to it, a hypothesis that needs to be tested with molecular phylogeny.Published as part of Couto, Dayvid R., Gonella, Paulo M. & Costa, Andrea F., 2023, Stigmatodon enigmaticus (Bromeliaceae, Tillandsioideae), a new lithophytic species from the Campos Rupestres within the Brazilian Atlantic Forest, pp. 207-215 in Phytotaxa 584 (3) on pages 209-212, DOI: 10.11646/phytotaxa.584.3.7, http://zenodo.org/record/764569

Este suplemento panamericano veio a público entre 1941 e 1949, no entanto a pesquisa aqui apresentada focalizou o período que compreendeu desde seu início até 1945, representativo marco do final da segunda Guerra Mundial e do Estado Novo. A primazia do enfoque recaiu sobre o estudo de mecanismos editoriais que permearam uma publicação oficial, bem como sobre a relação estabelecida entre os intelectuais acima apontados e o governo estadonovista. Abstract : This dissertation purpose is to study the editorial activity of Rui Ribeiro Couto and Renato Costa Almeida while these intellectuals were editors of a publication linked to the newspaper of Estado Novo (A Manhã). This publication was called Pensamento da America and was a monthly pan-American journal published between 1941 and 1949. However, this research focused on the period between 1941 and 1945, year that represents the end of the Second World War and the end of the Estado Novo. The focus was on the study of mechanisms that permeated the edition of an official publication, as well as on the relation between these intellectuals and the Estado Novo

Pabstiella pseudotrifida is very similar to P. trifida, but can be distinguished by the subtruncate to truncate petals, and the smooth lip which is free of callosities and truncate to rounded at apex. Plant epiphytic, 2-4 cm tall, caespitose, erect. Roots whitish, terete, flexuose, glabrous. Ramicauls 5.5-7 mm long., green, cylindrical, enclosed by tubular, acute, pale green sheaths that are paleaceous and whitish when dried. Leaves 16-28 X 3-3.5 mm, 0.8-1.6 mm thick, green, linear-elliptic, the base subpetiolate, the apex minutely 3-dentate, Inflorescence a congested, successively several-flowered raceme, 1.2-1.7 cm long, shorter than the leaves. Floral bracts ca. 1.5 mm long, translucent, pale green, tubular, acute. Flowers resupinate, glabrous. Pedicels 1.5-2 mm long. Ovary 1-1.2 mm long. Sepals yellow, translucent, with orange margins, 3-veined, carinate abaxially, the dorsal sepal 5-5.5 X 1.9-2 mm, oblong-elliptic, obtuse, the laterals sepal 4-4.1 X 1.4-1.5 mm, connate to above the middle into a oblong synsepal with acute apices, forming a small mentum below the tip of the column-foot. Petals 2.6-3.3 X 1.2-1.4 mm, spathulate, curved, 3-veined, translucent yellow with orange veins, slightly carinate abaxially, subtruncate to truncate. Lip 2.5-2.6 X 0.91 mm, orange, slightly purplish-lilac at base, green at the attachment with the column-foot, 3-lobed, unguiculate, 3-veined, the midvein longer than the laterals, smooth, free of callosities, the lateral lobes more or less below the middle, erect, broadly rounded, the apical lobe truncate to rounded. Column ca. 2.5 mm long, greenish, winged above the middle, white and 3-dentate at apex, the teeth straight and acute; column-foot 1.3-1.8 mm long with two callosities at base the apex papillose. Anther ca. 0.7 mm long, yellowishwhite; pollinia two, yellow. Capsule unknown. Etymology. – The specific epithet refers to its similarity to P. trifida (Lindl.) Luer. Habitat, distribution. – This species is apparently endemic to the Atlantic forest of southern Espírito Santo, growing as an epiphyte in dense rainforest remnants, from 800 to 1600 m altitude. It is partially protected in the mountain forests of the Caparaó National Park (Fig. 2). Conservation status. – Due to the apparently endemic distribution of P. pseudotrifida, and on the basis of the extension of its occurrence in the State of Espírito Santo, which is estimated to be less than 500 km 2, it seems appropriate to include this new species in the “Endangered” (EN) category (B2a(iii)), according to the IUCN (2001). Taxonomical notes. – Pabstiella pseudotrifida is most similar to P. trifida, from which it may be distinguished by its petal and lip morphology. In P. pseudotrifida the petals are subtruncate or truncate, and the lip is smooth, free of callosities, truncate or rounded at apex, with side lobes above the middle. In P. trifida, the petals are obtuse or acute, the lip is papillose or verrucose, the side lobes are near or below the middle, and the disc is shallowly channelled between a pair of verrucose, intramural calli.

Stigmatodon ilhanus Leme & D. R. Couto 2022, sp. nov.
No full textStigmatodon ilhanus Leme & D.R. Couto, sp. nov. (Figs. 4 A–E) Diagnosis: ___ This new species is morphologically similar to S. rosulatulus, but can be differentiated by: leaf blades narrowly triangular (vs. suboblong to sublinear), completely obscured on both sides by a dense layer of cinereous trichomes (vs. the green or purple color not obscured by the trichomes except for the parts covered by white irregular crossbands), sepals vinaceous-nigrescent (vs. greenishcastaneous with vinaceous margins), petals greenish (vs. yellowish-white), with larger appendages (9–10 × 3 mm vs. ca. 7 x 2 mm), and stigma blades sparsely and inconspicuously papillate (vs. densely papillate). Type: — BRAZIL. Bahia: Guaratinga, Buranhém, Pedra do Ferreiro, conjunto Fazenda Santa Clara, 536 m elevation, 16° 33’ 36.28” S, 40° 00’ 53.68” W, May 2015, A . Ilha s.n., cult. E . Leme 8997 (holotype RB!). Description:— Plants rupicolous, flowering ca. 42 cm tall. Leaves 25–30 in number, densely rosulate, thin coriaceous, forming a broadly funnelform rosette; sheath broadly elliptic, 6–8 × 5–7 cm, densely and minutely pale castaneous lepidote on both sides, nerved when dry; blade narrowly triangular, acuminate-caudate, nearly flat toward the apex, subspreading to recurved, 8–11 cm long, 2.5–3 cm wide at the base, completely covered on both sides with a dense layer of cinereous trichomes obscuring the color of the blade, margins reddish, inconspicuously truncate. Peduncle suberect or abruptly bending just above the rosette, 17–20 cm long, 0.3–0.4 cm in diameter, dark purplish to nigrescent, glabrous, not sulcate at anthesis; peduncle bracts the basal ones subfoliaceous, the upper ones ovate, attenuate and apiculate to obtuse, 14–20 × 8 mm, equaling to distinctly shorter than the internode, abaxially densely white lepidote mainly toward the apex, clasping the peduncle, nigrescent except for the stramineous margins. Inflorescence simple, suberect, linear in outline at anthesis, ca. 12 cm long, 7–8-flowered; main axis smooth at anthesis, nigrescent, glabrous, bluntly if at all angled, slightly flexuous, internodes 1–2 × 0.2–0.3 cm; floral bracts broadly ovate to broadly elliptic, obtuse, 8–13 × 7–9 mm, sparsely and inconspicuously white lepidote on both sides, ecarinate, remote, secund with the flowers at anthesis, thin coriaceous, lustrous, smooth, nigrescent, about reaching 1/3 of the sepal length. Flowers ca . 37 mm long (with petals extended), nocturnal, with a garlic odor, distichous, laxly disposed, distinctly secund at anthesis; pedicel 5–6 mm long, ca. 7 mm in diameter at distal end, stout, nigrescent, glabrous; sepals ovate, rounded, 17–18 × 9–10 mm, vinaceaous-nigrescent, sparsely and minutely white lepidote on both sides, smooth, ecarinate, thin coriaceous, apical margins membranaceous; petals obovate, apex broadly rounded and emarginate, recurved near the apex at anthesis, ca. 30 × 17 mm, pale greenish, thicker toward the base, bearing 2 appendages at the base; appendages 9–10 × 3 mm, spathulate, basally adnate to the petals for ca. 5 mm, apex bifid-caudate to caudate; corolla campanulate, 26–30 mm in diameter; stamens in pairs facing each petal at anthesis; filament free, 19–20 × 1.5 mm; anther ca . 7 mm long, dorsifixed near the base, base bilobed, apex obtuse; stigma tubo-laciniate type II, campanulate, margins entire to inconspicuously crenulate, sparsely and inconspicuously papillate, ca. 2.5 mm in diameter, green; ovules distinctly caudate at the distal end. Capsules unknown. Etymology: ___ The name of this new species honors the conservationist and climber André Ilha, who has brought countless bromeliad species found in difficult-to-access vertical cliffs from granitic inselbergs of southeastern Brazil to our attention. He documented this new species in the field and provided the specimens used in this study. Distribution and habitat:— Stigmatodon ilhanus is an ephilitic species, living on bare, nearly vertical granitic surfaces of inselbergs located in the district of Buranhém, county of Guaratinga, Bahia state, near the border with Minas Gerais. At the type locality, the heliophytic rosettes are scattered and form small to medium-sized groups of plants. Preliminary conservation status: ___ Vulnerable [VU: D2]. Stigmatodon ilhanus is only known from its type locality, at the Pedra do Ferreiro, a lowland inselberg from the southern region of Bahia, with the AOO of 4 km ² (AOO), and EOO undefined. Due to the apparent rarity and restricted distribution, with its small populations outside any conservation unit, and thus unprotected and prone to the effects of stochastic events in the near future, it seems prudent to include this species in the Vulnerable category [VU: D2]. However, the region of Guaratinga forms impressive inselberg landscapes, and new research in this region may change the conservation status of S. ilhanus. Observations: ___ Stigmatodon ilhanus is closely related to S. rosulatulus, living in ecologically similar habitats. This new species can be clearly distinguished mainly by the combination of leaves completely cinereous and obscured on both sides by a dense layer of trichomes (vs. leaves not obscured by the trichomes except for the parts covered by white irregular crossbands), and sepals vinaceous-nigrescent (vs. greenish-castaneous with vinaceous margins). Its stigma belongs to the tubo-laciniate type II, which allows grouping S. ilhanus with the species of Stigmatodon s.l. The stigma blades with sparse and inconspicuous papillae (fig. 1 J–K) differ from the densely papillate stigma of its close relative (figs. 1 M–N).Published as part of Leme, Elton M.

Impactos da Covid-19 na associação de catadores de materiais recicláveis do município de Itacoatiara-AM
No full textO presente estudo buscou analisar dados relevantes provenientes da pandemia na Associação de Catadores de Lixo de Itacoatiara-AM (ASCALITA). Foram realizadas visitas técnicas na Associação, bem como entrevistas semiestruturadas com 11 catadores em janeiro e fevereiro de 2022, as quais possibilitaram identificar problemas enfrentados, por meio da metodologia de análise Strengths, Weaknesses, Opportunities, Threats (SWOT). Com isso, foi observado que a maioria dos catadores possui Ensino Fundamental, renda inferior ao salário-mínimo e vivem em condições insalubres. Além disso, foi observado que durante a pandemia da COVID-19, os catadores não paralisaram a catação, contraíram o vírus da COVID-19 e tiveram danos econômicos. A falta de infraestrutura, aparecimento de novos concorrentes e baixo preço dos materiais recicláveis prejudicaram as atividades da Associação. Os resultados do presente estudo mostram a necessidade de atenção por parte do poder público e sociedade em geral com os catadores de materiais recicláveis, uma vez que esses atores são responsáveis pela minimização de impactos socioambientais
