Chapada das Mesas National Park (CMNP) is the fourth largest conservation unit in Maranhão state and an important area for the study of bryophytes due to its geomorphological characteristics, predominant vegetation, and water potential. The aim of our study was to investigate the richness and composition of leafy liverwort species in CMNP, discuss the importance of this area in the state, and present an updated checklist of the leafy liverworts for Maranhão. Our botanical material was collected during four excursions to the park. The checklist was mainly based on literature reports. Forty-one species and two varieties in eight families and 20 genera were identified in CMNP. From the state of Maranhão, 106 species and two varieties in nine families and 39 genera are reported. Our survey of bryophytes in CMNP resulted in the first records from Maranhão of 19 species. Lejeunea juruana Gradst. & M.E.Reiner is also newly found in the Northeastern region of Brazil and in the Cerrado domain.

We report a floristic survey of the species of Clusiaceae s.l. (Calophyllaceae, Clusiaceae s.s., and Hypericaceae) in the Viruá National Park (Roraima, Brazil). The fieldwork was conducted between 2009 and 2015 and covered the different vegetation types found in the park. Calophyllaceae is represented by two genera and three species, Clusiaceae s.s. by five genera and 12 species, and Hypericaceae by one genus and five species. Three species are new records for the state of Roraima. We present an identification key, updated taxonomic descriptions, and photographic illustrations for each species. Two lectotypifications are proposed for Clusia. A new combination in Garcinia is also proposed.

<p>O presente estudo tem como objetivo aferir, para o período entre 2008 e 2019, o regime de queima no Parque Nacional da Chapada dos Veadeiros (PNCV), Unidade de Conservação (UC) localizada no estado de Goiás que teve sua área ampliada neste período. A partir de imagens dos satélites Landsat e CBERS, cicatrizes de incêndio foram identificadas, vetorizadas e analisadas quanto à localização, ao tamanho e à frequência. A área atual do PNCV queimou cerca de 542.113 hectares, i.e., mais de 225% da área da UC. Aproximadamente 76% das cicatrizes foram registradas na área ampliada do Parque, a qual teve a maior participação de incêndios em 10 dos 11 anos analisados. Foi possível discriminar dois regimes de queima: um que abrange o limite antigo do Parque, caracterizado por baixa ocorrência de queimada, com presença de feições que se assemelham a aceiros e baixa frequência de incêndios; e outro na área ampliada, com histórico de queima anual com valores mais próximos à média, ausência de cicatrizes lineares e frequência máxima de 10 ocorrências. A unificação destes panoramas em um só território exigirá esforços para homogenização dos regimes e poderá, associada a outras ações, diminuir a imprevisibilidade dos incêndios, e respectivos impactos, legitimando o papel que as UCs possuem para a conservação e a preservação da natureza.</p><p>Abstract</p><p>OCCURRENCE OF FIRE IN THE CHAPADA DOS VEADEIROS NATIONAL PARK, GOIÁS, BRAZIL: RECENT HISTORY IN THE CONTEXT OF ITS EXPANSION</p><p>The present study aims to assess, for the period between 2008 and 2019, the burning regime in the Chapada dos Veadeiros National Park (CVNP), Conservation Unit (CU) located in the state of Goiás that had its area expanded in this period. From images of Landsat and CBERS, fire scars were identified, vectorized, and analyzed for their location, size, and frequency. The current area of the CVNP burned about 542,113 hectares, i.e., more than 225% of the area of the CU. Approximately 76% of the scars were recorded in the expanded area of the Park, which had the highest participation of fires in 10 of the 11 years analyzed. It was possible to discriminate two burning regimes: one that covers the old limit of the Park, characterized by the low occurrence of fire, with the presence of features that resemble firebreaks and low frequency of fires; And another in the enlarged area, with a history of annual burning with values closer to the average, absence of linear scars and a maximum frequency of 10 occurrences. The unification of these panoramas in a single territory will require efforts to homogenize the regimes and may, associated with other actions, reduce the unpredictability of fires, and their impacts, legitimizing the role that CU have in the conservation and preservation of nature.</p>

As lianas e trepadeiras são importantes componentes das unidades florestais, principalmente em regiões tropicais, as quais se diferenciam, especialmente, pelo grau de lenhosidade no seu caule. Esses grupos contribuem notavelmente para a riqueza de espécies de diferentes ecossistemas, trazendo benefícios para a flora e fauna. No entanto, constituem o componente menos estudado, gerando uma lacuna no conhecimento sobre aspectos florístico-estruturais, regenerativos e fatores que influenciam esses grupos nas diversas formações vegetacionais. Esse estudo objetivou realizar o levantamento das espécies de lianas e trepadeiras registradas no Parque Nacional de Ubajara (PARNA Ubajara), no estado do Ceará. As informações sobre as espécies foram obtidas através de consulta aos bancos de dados digitais Flora do Brasil 2020 e Centro de Referência em Informação Ambiental – CRIA. Com base nessas informações, foi elaborada uma lista de espécies e uma chave de identificação das famílias botânicas registradas. No PARNA Ubajara foram listadas 60 espécies, distribuídas em 42 gêneros e 20 famílias de lianas e trepadeiras, com destaque para Fabaceae (25%), Bignoniaceae (8,3%) e Convolvulaceae (8,3 %), correspondendo a 41,6 % do total de táxons. Tais famílias foram representadas em outros remanescentes de Mata Atlântica, mostrando uma similaridade florística entre essas áreas. O estudo mostrou a importância dos inventários florísticos com esses grupos de plantas, os quais podem servir como subsídio para a criação de programas de conservação de espécies, principalmente para aquelas que estão na categoria de pouco preocupante, segundo o livro vermelho da flora do Brasil, e que foram registradas na área de estudo.  Diversity of Climbers of the Ubajara National Park, Ceará, BrazilA B S T R A C TLianas and vines are important components of forestry units, especially in tropical regions, which are differentiated mainly by the degree of woodiness in their stem. These groups contribute notably to the richness of species from different ecosystems, bringing benefits to flora and fauna. However, they constitute the least studied component, generating a gap in knowledge about floristic-structural, regenerative aspects, and factors that influence these groups in the different vegetation formations. This study aimed to survey the species of lianas and vines recorded in the National Park of Ubajara (PARNA Ubajara), in the state of Ceará. The information about the species was obtained through consultation with the digital databases Flora do Brasil 2020 and Reference Center for Environmental Information - CRIA. Based on this information, a list of species and an identification key for the registered botanical families were prepared. In PARNA Ubajara, 60 species were listed, distributed in 42 genera and 20 families of lianas and vines, with emphasis on Fabaceae (25%), Bignoniaceae (8.3%) and Convolvulaceae (8.3%), corresponding to 41.6 % of total taxa. Such families were represented in other remnants of the Atlantic Forest, showing a floristic similarity between these areas. Floristic inventories are important to these groups of plants, which can serve as a subsidy for the creation of species conservation programs, especially for those that are in the category of little concern, according to the red book on flora in Brazil, and that were recorded in the study area.Key words: Floristic, Atlantic forest, Northeast of Brazil, Conservation unit.

The Jaú National Park, located in the Amazon, is the largest National Park of Brazil and still its insect fauna is barely known. Herein we describe two new species of Psychodinae, Alepia iy sp. nov. and Parasetomima timmirima sp. nov., and report 19 other species of Psychodidae, subfamilies Phlebotominae, Psychodinae and Trichomyiinae collected from this Conservation Unit. Micrommatos Quate & Brown, represented by M. stephaniae Quate & Brown, and Platyplastinx culmosus Quate & Brown are recorded for the first time for Brazil. Among the collected phlebotomine sand fly species, three species have previously been implicated in transmission of Leishmania: Nyssomyia anduzei (Rozeboom), Psychodopygus ayrozai (Barretto & Coutinho) and Trichophoromyia ubiquitalis (Mangabeira).

Serra da Pedra Branca (SPB) is a mountain range located in the Southwestern portion of the state Minas Gerais, in the municipality of Caldas (21°58′-21°55′S, 46°24′-46°22′W). It is a striking feature in the landscape, between 1100 and 1780 m.s.m., in a region that is part of the Atlantic Forest Domain and is considered as a priority area for conservation of the flora in Minas Gerais state. The vegetation is composed by a mosaic of “campo de altitude” (which occupy the greatest extension in the area), Seasonal Semidecidual Montane Forest, Dense Ombrophilous High-Montane Forest and Mixed Ombrophilous Forest. The aims of this study was the elaboration of a floristic survey of SPB added to the specimens collected by Anders Fredrik Regnell in the nineteenth century in Caldas and to analyze its floristic similarity with altitude areas of the Southeastern Region of Brazil. There were recorded 502 vascular plant species, distributed in 274 genera and 100 families. The majority of recorded species present herbaceous habit, terricolous, saxicolous and/or rupicolous (representing around 58% of recorded species), predominantly occurring in the “campo de altitude” (ca. 46%). The richest families were Polypodiaceae (20 spp.) and Dryopteridaceae (10 spp.) among the ferns, and Orchidaceae (56 spp.), Asteraceae (27 spp.) and Fabaceae (26 spp.) among the angiosperms. Just one species of gymnosperm was recorded, Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae). Five new records were made for the Minas Gerais flora, 13 species are cited as threatened with extinction in the state and at least six are endemic to SPB. Amongst 127 species collected in XIX century in the region, only 29 collected again, while 375 new records were made for SPB. The analysis of floristic similarity performed between the flora of SPB and other altitude areas of Southeastern Region revealed isolation of SPB in relation to other areas, highlighting its floristic peculiarity, which can probably be explained by its location in a distinct hydrographic basin. The vegetation of the SPB must be considered as endangered since the presence of endemic species and/or threatened species, associated with local environmental conditions suffering accelerated rate of destruction, highlight the need for urgent actions to preserve local biodiversity.

La colonización dirigida, espontánea y estratégica, además de la permanente ampliación de la frontera agrícola para la extracción de recursos naturales, han determinado el uso y zonificación del espacio amazónico en los últimos 50 años. Las drásticas huellas socio-económicos, culturales y ambientales generadas por estos procesos han impactado negativamente la vida de los pueblos ancestrales y la naturaleza. Una consecuencia drástica es el cambio de la comprensión de la territorialidad en el interior de los territorios indígenas, y de la percepción que de aquel cambio tienen el Estado y los actores asentados en el entorno territorial comunitario. El presente estudio aborda el caso del pueblo waorani e inquiere cómo la ampliación de la frontera extractiva intensificaría los impactos negativos del proceso de desterritorialización en el Parque Nacional Yasuní, poniendo en mayor riesgo la integridad física y cultural de los de los pueblos que viven en aislamiento voluntario: Tagaeri y Oñamenane u otros de los cuales no se tiene referencia.   Abstract Targeted, spontaneous and strategic colonization, in addition to the permanent expansion of the agricultural frontier for the extraction of natural resources, has determined the use and zoning of the Amazonian space in the las 50 years. The drastic socioeconomic, cultural and environmental impacts generated by these processes have impated negatively the life of the ancestral peoples and nature. A drastic consequence is the change of the understanding of the territoriality in the interior of the indigenous territories, and the perception that the state and the actors settled in the community territorial environment have of that change. This study addresses the case of the Waorani people and inquires how the expansion of the extractive frontier would intensify the negative impacts of the process of decentralization in the Yasuní National Park, putting at greater risk the physical and cultural integrity of the peoples living in voluntary isolation: Tagaeri and Onamenane or others of which there is no reference.

This study evaluated the Arctiini fauna of the Serra do Pardo National Park (Pará, Brazil) between 22 September and 3 October 2011. Light traps were left one night in each sampling site (SS) from 18:00 h to 6:00 h of the next day. The following parameters were evaluated: richness (S), abundance (N), diversity index (H’), Shannon uniformity (U) index, and Berger-Parker dominance (BP). Richness was estimated using the non-parametric methods Chao1, Chao2, ACE, ICE, Jackknife1, Jackknife2 and Bootstrap. A total of 3,247 specimens were captured, belonging to 221 Arctiini taxa; 32 of these are new records for the state of Pará and, of these, six are new records for the Brazilian Amazon. The Arctiini fauna is very rich and uniform. The richness estimator and rarefaction curve indicated the need for increased sampling efforts in the area.

Abstract A taxonomic treatment of the genera Turnera and Piriqueta in the state of Pernambuco, northeastern Brazil, is presented. Fourteen species of Turnera and six species of Piriqueta were found in the Atlantic Forest and Caatinga, of which nine are endemic to Brazil. Turnera pernambucensis is threatened and restricted to the Atlantic Forest of Pernambuco, while T. joelii is a new record for the state. The species predominate in steppe savanna and semideciduous seasonal forest, but several of them grow naturally in anthropized areas. Catimbau National Park is the locality with the highest species richness. Tristyly is recorded for the first time in Piriqueta guianensis. Identification keys, descriptions, illustrations, distribution maps, and comments about habitat, flowering, fruiting, and morphological relationships are provided.
