Hemeróbidos (Insecta: Neuroptera: Hemerobiidae) de la sabana del centro de Brasil

In this study were documented the species of brown-lacewings (Neuroptera: Hemerobiidae) found at Parque Nacional da Chapada dos Veadeiros, in Alto Paraíso de Goiás, state of Goiás and at Parque Nacional Grande Sertão Veredas, in Chapada Gaúcha, state of Minas Gerais, both in Brazil, based on a survey carried out with Malaise traps between February 2018 and May 2019. During the samplings 60 specimens of hemerobiids were captured, being 26 of Nusalala tessellata (Gerstaecker, 1888), 13 of Nomerobius argentinensis González Olazo, 1990, eight of Sympherobius amazonicus Penny & Monserrat, 1985, six of Megalomus impudicus (Gerstaecker, 1888), five of Hemerobius hernandezi Monserrat, 1996, one Nomerobius cuspidatus Oswald, 1990 and one of Notiobiella sp. Nomerobius argentinensis and Nom. cuspidatus are reported by the first time to Brazil and H. hernandezi, M. impudicus, Notiobiella sp. and S. amazonicus to the state of Goiás, Brazil.

Rediscovery of the Blue-necked Tanager Stilpnia cyanicollis albotibialis in the Chapada dos Veadeiros, Goiás, Brazil

We report a new record of the Blue-necked Tanager Stilpnia cyanicollis albotibialis in the Chapada dos Veadeiros, Brazil, which could represent its rediscovery after nearly 100 years without documented records. S. c. albotibialis was known only from its holotype, collected at the Chapada dos Veadeiros, in central Brazil, in December 1929 by José Blaser, and held at the Field Museum of Natural History, Chicago. We present behavioural data and comment on the biogeography of this subspecies, as no information concerning its ecology has been previously published.

Gomphonema Ehrenberg (Bacillariophyta) de córregos prístinos do Cerrado brasileiro

This study aimed to survey the species of Gomphonema Ehrenberg in pristine Cerrado streams located in the Brasilia National Park, Chapada dos Veadeiros National Park and Terra Ronca State Park, located in the midwestern region of Brazil. Samples were taken between the years 2012 and 2013 (rainy and dry seasons), with the periphyton collected from seven different substrates, whenever they were present (pebbles, silt, tree trunk, macrophytes, sand, leaf litter and root). We identified 10 taxa in this study. The species Gomphonema sp.2 was present in all streams, and G. lagenula and G. brasiliense were the species with the highest frequency of occurrence in both seasonal periods. This study contributed with three species cited for the first time for the midwestern region (G. brasiliense subsp. pacificum, G. laticollum and G. pseudoaugur).

Novelties in Dyckia (Pitcairnioideae ‐ Bromeliaceae) from the South America dry diagonal: Two new species, a new combination and a new name

AbstractDyckia is a South American genus mostly distributed in the Brazilian Cerrado and Caatinga domains, which are part of the South American dry diagonal where it represents an important floristic and ecological component. Following phylogenetic studies, the genus was recently expanded to include species previously placed in Encholirium and Deuterocohnia. With this new delimitation, Dyckia comprises ca. 220 species, of which some are micro‐endemic. We present novelties in the genus for the South American dry diagonal based on fieldwork, herbarium specimens and the literature. Two new micro‐endemic species are described: Dyckia avacanoeira, endemic to Chapada dos Veadeiros; and Dyckia oreadica, endemic to the Jalapão region. We provide complete descriptions, illustrations, distribution maps, photographs, preliminary conservation assessments and comments on the taxonomy and ecology of the two species. Additionally, in view of the new circumscription of Dyckia, we provide a new name, Dyckia viridiflora, to replace an illegitimate name, and a new combination, Dyckia josinoi‐narcisae, for a species previously placed in Encholirium.

<p><strong><em>Hyptis lavoisierifolia</em>, a new species from the noteworthy <em>Hyptis</em> subsect. <em>Pachyphyllae</em> (Lamiaceae—Hyptidinae) endemic to Chapada dos Veadeiros region, Goiás, Brazil</strong></p>

Hyptis is a genus with about 151 species that belongs to subtribe Hyptidinae, a monophyletic and predominantly Neotropical group from Lamiaceae. The genus has gone through a series of taxonomic changes, especially sectional, since the early 19th century. Hyptis sect. Eriosphaeria subsect. Pachyphyllae, recent reestablished as subsection, is composed, until this paper, of four species, all endemic to the Chapada dos Veadeiros region, in Goiás state, Brazil. Here we report a novelty for the subsection.

<p><strong>Seek and you shall find: rediscovery of the Brazilian <em>Euphorbia burchellii</em> (Euphorbiaceae) after nearly a century and a half, with a conspectus of <em>Euphorbia</em> sect. <em>Anisophyllum</em> species in the state of Goiás, Brazil</strong></p>

During a taxonomic study of Euphorbia from Goiás state, Brazil, we came across some small populations of an unfamiliar species of the genus in the Chapada dos Veadeiros region. After detailed analyses of these specimens we concluded that they correspond to E. burchellii (E. section Anisophyllum), a species hitherto known only from its type locality. We present an amended description of E. burchellii, provide the first information about its fruits and seeds, as well as its lectotipification. We also include illustrations and field photographs, comments on its geographical range along with a distribution map, a recommendation for conservation status, phenology, morphological relationships, and systematic position. Finally, we also provide a key to the 14 species of E. section Anisophyllum occurring in Goiás State.

Geographic distribution patterns of species of the subtribe Lychnophorinae (Asteraceae: Vernonieae)

Abstract With 119 species distributed in 19 genera, most species of the subtribe Lychnophorinae are endemic to the Espinhaço Range in central eastern Brazil. This region is characterized especially by the campos rupestres, a grassland mosaic associated with vegetation on rock outcrops, which display a high level of endemism. The present work aims to identify distribution patterns, collection density, species richness and research bias in collections. Ten geographic distribution patterns were identified: Chapada Diamantina, Chapada dos Veadeiros and adjacent mountains, Pico da Aliança, Extension of the Espinhaço Range, Central-South Arc of Minas Gerais, Espinhaço Range and Brasília Arc, Campos Rupestres and Restinga, Chapada Diamantina and Caatinga, Northwest-Southeast Diagonal and East Triangle. Other Angiosperm families present similar distribution, mainly in the Espinhaço Meridional, where higher collecting efforts are present. Species richness is higher in sites with higher collection intensity, however, the northeast of Goiás shows the opposite pattern. Spearman correlation analysis shows a strong correlation between collection density and species richness, with an exponential asymptotic model that is quite significant for the total variation of species richness. The cluster analysis presented five clusters correlated with five distribution patterns in Lychnophorinae.

Five new clavate-stigma Waltheria species endemic to Brazilian Cerrado (Malvaceae s. l., Byttnerioideae, Hermannieae)

Five new species are described and illustrated: Waltheria hatschbachii, W. hoehnei, both endangered for extinction, W. coriacea, W. flavovirens and W. matogrossensis. All are endemic to Brazil, in Cerrado s. l. associated with the Brazilian Plateau in N, NE, CW, and SE Brazil. Their affinities and the distinctness from W. ferruginea s. l. are discussed, and they are associated and compared with W. ferruginea s. str., from cerrado, W. brachypetala, from caatinga, W. biribiriensis and W. terminans, both from campo rupestre. The geographic distribution of all nine species is illustrated, and a new identification key for these and for the two sections of Waltheria is provided. All nine species share a clavate stigma in pin (or thrum) flowers, that morphotype given earlier as distinguishing one of three main species groups of the genus, and a new character, the ferruginea type stipitate-stellate trichome, illustrated here. Subconduplicate petals are first reported in the tribe Hermannieae, often keyed by flat petals. Waltheria is first signaled here to present the same enigmatic biogeographical pattern noted before for Triraphis (Poaceae) between Chapada dos Veadeiros, Africa and Australia. Other new taxonomic characters for Waltheria are given.

A new species of Characidium (Characiformes: Crenuchidae) from the Chapada dos Veadeiros, Goiás, Brazil

Abstract A new species of Characidium is described from the tributaries of the rio Tocantinzinho, rio Tocantins basin, located in the southern portion of the Chapada dos Veadeiros, at about 1,200 meters of elevation, Goiás, Brazil. The new species can be diagnosed by an unusual combination of two apomorphic features present in distinct clades of Characidium, the presence of a scaleless isthmus in allied to with a single row of dentary teeth. Additionally, the new species has a unique color pattern of inconspicuous vertical bars disconnected from the dorsal midline, forming seven to nine square blotches along body sides, and the presence of a dark saddle-shaped mark at the dorsal-fin base. Osteologically, it can be diagnosed by having the first and second anal-fin proximal radials fused and contacting the third hemal spine, which is branched. The new species also has a peculiar, unusual variation of fin-ray counts among its congeners.

Two New Species of Anthrenoides Ducke, 1907 (Hymenoptera: Apidae: Andreninae) with a Checklist of Andrenine Bees of Cerrado Savanna

In Neotropical region, the subfamily Andreninae is commonly collected in temperate and subtropical areas with scarce records in tropical areas. Here, we provide a checklist of andrenine bees from Cerrado and describe two new species of Anthrenoides. Twenty-two bee species of Andreninae were recorded. The new species were recorded in the core area of Cerrado, on Brazilan Central Plateau. Anthrenoides kalungasp. nov. is known by a single female specimen from Chapada dos Veadeiros and it is easily recognized by the hairy mesosoma. Anthrenoides urbanaesp. nov. was collected in a grassland area of Cerrado, and is distinguished from other species by glossa and galea longer than compound eyes. A. urbanaesp. nov. is associated with flowers of Alstroemeria gardneri (Alstroemeriaceae) which are used as a source of food and mating sites. The small number of Andreninae bee species recorded on Cerrado is possibly a result of a shortfall of inventories that can be solved by an additional effort to sample these rare bees with specific methods like UV pan traps.

Ocorrência de fogo no Parque Nacional da Chapada dos Veadeiros, Goiás, Brasil: histórico recente no contexto da sua ampliação

<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>

Tropical riparian forests in danger from large savanna wildfires

Abstract Tropical savannas are known for the fire‐prone ecosystems, yet, riparian evergreen forests are another important landscape feature. These forests usually remain safe from wildfires in the wet riparian zones. With global changes, large wildfires are now more frequent in savanna landscapes, exposing riparian forests to unprecedented impact. In 2017, a large wildfire spread across the Chapada dos Veadeiros National Park, an iconic UNESCO site in central Brazil, raising concerns about its impact on the fire‐sensitive ecosystems. By combining remote sensing analysis of Google Earth images (2003–2019) with detailed field information from 36 sites, we assessed wildfire impacts on riparian forests. For this, we measured the structure of trees, saplings and herbaceous plants, as well as topsoil variables. Since 2003, all riparian forests had canopy cover above 90%, but after 2017, canopy cover dropped to 20% in some forests, indicating large variation in wildfire damage. A closer look in the field revealed that, on average, the wildfire killed 52% of adult trees and 87% of tree saplings in flooded forests. In non‐flooded forests, impacts on adult trees were negligible, but fire killed 75% of tree saplings. Opportunistic vines and the invasive grass Melinis minutiflora were already present in severely disturbed flooded forests. In all forests, impacts on many ecosystem variables were related to canopy damage, a variable measurable from satellite. Overall, seasonally flooded riparian forests were the most severely impacted, possibly due to the relatively thinner barks of their trees. Synthesis and applications. Our findings reveal how riparian forests embedded in tropical savanna landscapes are in danger from large wildfires. The destruction of some forests has opened space for new plant species that may propel a shift to an alternative ecosystem state. Riparian forests are habitat of large savanna animals and their loss could affect entire trophic networks. Managing wildfires and invasive grasses locally is probably the best strategy to maintain riparian forests resilient. As wildfire regimes intensify in tropical savanna landscapes, our findings stress the need for an integrated management that considers riparian forests as a vulnerable element of the system.

Hemipogon trilobatus sp. nov. (Apocynaceae: Asclepiadoideae), a new microendemic from Chapada dos Veadeiros, Central Brazil

Hemipogon s. str. (Apocynaceae: Asclepiadoideae) currently consists of three species sharing an erect herbaceous habit, narrow leaves and corona-less flowers with urceolate, internally bearded corolla, that are mainly distributed in savannahs of the Cerrado biodiversity hotspot, South America. Here, we describe and illustrate a new species of Hemipogon, H. trilobatus Bitencourt & Rapini sp. nov., from an open savannah in Chapada dos Veadeiros, Central Brazil. Hemipogon trilobatus sp. nov. differs from the other species of the genus mainly by the presence of a reduced staminal corona with 3-lobed lobes, but also by opposite leaves and triangular anthers. Distribution and habitat data, as well as a key and a comparative table to distinguish the four species currently accepted in Hemipogon s. str., are provided. Based on criteria B2ab(i,ii,iii,iv) of the International Union for Conservation of Nature (IUCN), the species is provisionally assessed as Critically Endangered.

Resíduos sólidos no Parque Nacional da Chapada dos Veadeiros

Meios de hospedagem são os maiores geradores de resíduos sólidos do setor turístico. No contexto da instituição da Política Nacional de Resíduos Sólidos e uma série de orientações sobre gestão sustentável de empreendimentos turísticos, elaboradas pelos órgãos públicos brasileiros, torna-se relevante avaliar as práticas dos meios de hospedagem nesse sentido. Este estudo analisa a gestão de resíduos sólidos nas pousadas e hostels de Alto Paraíso (GO), cidade com a maior capacidade de alojamento mais próxima da entrada do Parque Nacional da Chapada dos Veadeiros. Trata-se de um estudo de caso, com coleta de dados por meio de entrevistas em dez meios de hospedagem e com um representante da associação de reciclagem local. Os resultados indicam uma fraca conscientização dos clientes, forte dependência de decisões das autoridades locais, pouca vontade de cooperar e desconhecimento de técnicas de minimização de resíduos sólidos.

Seasonal Variation in Mycorrhizal Community of Different Cerrado Phytophysiomies.

Purpose: Understanding the dynamics of mycorrhizal fungi in the Cerrado is fundamental for the adoption of conservation practices and for understanding the resilience of this biome in relation to long periods of drought. Thus, this work aimed to verify the dynamics of the mycorrhizal population in five phytophysiognomies of the Cerrado biome.Methods: The samples were taken from the Chapada dos Veadeiros National Park, a permanent preservation with native Cerrado vegetation without any anthropic influence. The five main phytophysiognomies of the Cerrado biome were chosen: the Campo Limpo, Campo Sujo, Cerrado Strictu Sensu, Cerradão, and Veredas. Rhizospherical soil samples were collected in both the wet and dry seasons. Spore density, mycorrhizal colonization rate, easily extractable glomalin, and associated mycorrhizal fungi genera were identified.Results: The values of spore density, mycorrhizal colonization rate, and glomalin were higher in the samples performed during the dry season compared to the samples performed in the rainy season. The same behavior was observed when comparing the different phytophysionomies.Conclusion: Mycorrhizal activity is higher in dry periods when compared to rainy periods. There is no specificity of genera of arbuscular mycorrhizal fungi within the Cerrado phytophysiognomies.

Two new species of Microlicia D.Don (Melastomataceae, Microlicieae) from Chapada dos Veadeiros, Goiás State, Brazil.

Microlicia gracilis and Microlicia xylopodifera, endemic to Chapada dos Veadeiros, Goiás State, Brazil, are described, illustrated and the conservation status is also provided. Both species resemble Microlicia ordinata and Microlicia ramosa that are also endemic to Goiás, by having sessile leaf with serrate and ciliate margin, pedicellate flower, triangular and short sepal and dimorphic stamens with bicolorous and polysporangiate anthers. However, M. gracilis differs by the long internode (2–4 mm long), concolorous, semi-amplexicaul and lanceolate leaf, and petal acuminate at the apex. Microlicia xylopodifera differs in having a robust xylopodium, horizontal or slightly ascending leaf and a dense crown of glandular trichomes at the apex of flower bud.

Geographic distributions of Pseudopaludicola boliviana and congeneric long-legged species (Anura: Leiuperinae)

ABSTRACT In recent years, the taxonomic knowledge of Pseudopaludicola has increased and it is currently possible to elucidate aspects of the species within this genus such as their geographic distributions. Here we accessed new data on geographic distribution of P. boliviana and three long-legged species of the P. saltica group (P. saltica, P. murundu, and P. jaredi). Based on morphometric, acoustic and genetic data, we accessed the specific status of long-legged specimens from Chapada dos Veadeiros highlands and attributed them to the P. murundu. We also performed a phylogenetic analysis including several populations of the three species. Based on this novel dataset, we discussed the geographical distributions of P. saltica, P. murundu, and P. jaredi, providing new records for them. Pseudopaludicola boliviana is one of the five species of the P. pusilla group and it is thought to be a widely distributed species based on its morphology. Hence, we evaluated the geographic distribution of P. boliviana, using novel acoustic data of specimens from Argentina, Northern Brazil, and Bolivia.

<p><strong>Taxonomic and morphological notes on a tiny new species of <em>Paepalanthus </em>(Eriocaulaceae) from central Brazil</strong></p>

We describe and illustrate Paepalanthus campanulatus, a new species of Eriocaulaceae from the Chapada dos Veadeiros National Park (Goiás, Brazil). The species is known from a single population with many individuals growing under rocks and in small caves, sometimes upside down attached to the top of the cave. The new species is mainly distinguished by its usually tiny, unbranched stem bearing a fasciculate inflorescence composed of mostly glabrous, campanulate capitula surrounded by whitish hyaline involucral bracts. Due to its very restricted distribution, the species may be considered endangered. It is compared with Paepalanthus albidus and P. subtilis, the morphologically most similar species. We provide details on the leaf and scape anatomy of these species, as well as comments on the distribution, habitat, ecology, and morphological variation, along with line drawings and photos of the new species.
