Authors: Bao Xi , Huang Bingge , Mao Yiting , Zhang Zhiguang , Zhou Yunfang , Wen Congcong , Zhou Quan
Published: February 2019

Byakangelicol is one of coumarins from Baizhi and has been shown to inhibit the release of PGE2 from human lung epithelial A549 cells in a dose-dependent manner. A sensitive ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was developed and full validated for the quantification of byakangelicol in rat plasma. The pharmacokinetics of byakangelicol after both intravenous (5 mg/kg) and oral (15 mg/kg) administrations were studied. Chromatographic separation was performed on an ultra-performance liquid chromatography ethylene bridged hybrid (UPLC BEH) C18 column with acetonitrile and 0.1% formic acid as the mobile phase at a flow rate of 0.4 mL/min; fargesin was used as the internal standard (IS). The following quantitative analysis of byakangelicol was utilized in the multiple reaction monitoring mode. The samples were extracted from rat plasma via protein precipitation using acetonitrile. In the concentration range of 1–2000 ng/mL, the method correlated linearity (r > 0.995) with a lower limit of quantitation (LLOQ) of 1 ng/mL. Intra-day precision was less than 11%, and inter-day precision was less than 12%. The accuracy was between 92.0% and 108.7%, the recovery was better than 89.6%, and the matrix effect was between 85.9% and 98.6%. The method was successfully applied to a pharmacokinetic study of byakangelicol after intravenous and oral administration, and the absolute bioavailability was 3.6%.

Authors: Barros Luana Machado , Soares Matheus Mickael Mota , Ale-Rocha Rosaly
Published: February 2019

Although Pantophthalmidae is widely distributed in Brazil, in some regions, such as the Amazon basin, there is a dearth of studies on the family. In this work, we record the occurrence of Pantophthalmus chuni (Enderlein, 1912) and Pantophthalmus comptus Enderlein, 1912 for the state of Roraima for the first time. In addition, we provide distribution maps and photographs of the species.
Playing the Myth
Authors: Asimos Vivian
Published: February 2019

As attention to popular culture academically grows, we can begin to see the connection between myth and popular culture. If myths are those narratives an individual or communities uses to understand themselves and the world around them, popular culture narratives have the increasing ability to fill this role. Video games, the largest entertainment industry in the world, make up contemporary mythology. However, saying video games are myth is significantly easier than actually attempting to study video games as myth. This paper seeks to demonstrate not only the connection between myth and video games, but also a theoretical approach to the study of the mythic video game. By using "implicit myth", a term which allows us to see the larger influence and experience of myth, we can detail a theoretical approach possible for the video game as myth.

KINETICS AND ENERGY OF POULTRY MEAT DEHYDRATION IN VACUUM AND MICROWAVE FIELD CONDITIONS
Authors: Burdo O. , Povarova N. , Melnyk L.
Published: February 2019

The article presents the results of obtaining dried poultry meat under vacuum conditions using ultrahigh electromagnetic energy sources. A characteristic of the most common principles of drying is presented, which shows that the trends in the technology of drying technology is a reduction of specific energy consumption. From literary sources it is known that this is the best way to preserve meat protein in the native state. This method of drying leads to the release of a large amount of heat, resulting in evaporation can occur at a low temperature. The heat dissipated is spent exclusively on the evaporation of moisture without heating the fabric of the product. The rational modes of microwave-vacuum drying for meat semifinished products are determined. Drying was carried out at a temperature below 40°C and a pressure of 8 kPa with simultaneous processing by an electromagnetic field at a frequency of 2.7 GHz. This contributes to the intensive evaporation of moisture without a significant change in the structure of the surface layer, reducing the length of processing. Microwave-vacuum drying provides high functional and technological properties, namely: moisture-binding ability, water-retaining, fat-retaining ability and mass fraction of residual moisture, and better organoleptic characteristics. According to the sensory evaluation, the samples studied had a more fragile consistency, characterized by dry powders, a pleasant taste and a flavor similar to boiled chicken meat. The article shows the dependence of the mass of condensate on the duration of drying. On the basis of what was determined the duration of drying of the meat additive, which is 3 hours, while the mass fraction of residual moisture is 4.5%. It was established that obtaining dried meat semis from poultry meat under vacuum conditions using ultra high frequency electromagnetic energy sources allows to receive products with less energy and for a shorter period of production.
REMOVAL OF MINERAL IMPURITIES FROM AFTER - HARVESTING RESIDUES OF CORN
Authors: STANKEVYCH G. , НONCHARUK H. , SHIPKO I. , LIPIN A.
Published: February 2019

Due to the energy crisis, special attention is paid to the production and use of biofuels. After-harvesting residues of corn (AHRC) may become a perspective source of energy for grain dryers. The following components of the AHRC are distinguished: stem, leaves, rod and wrapper of the cob. The AHRC is about 55...60% of the total weight of the plant. The annual harvest of corn grain is more than 20 million tons. The calorific value at burning of wheat straw is 14.4 MJ/kg, AHRC -15.7 MJ/kg. For comparison, the calorific value of wood on average is 14.24 MJ/kg, and natural gas is 33.5 MJ/m3 [1]. Using the AHRC can significantly reduce the need for imported gas. One of the directions of the use of plant raw materials as fuel is the production of granules [2]. The technology involves purifying raw materials from impurities, crushing and granulation. For a similar scheme, granulated feeds are produced. When picking up a harvester, following transportation and reloading, various contaminants, including mineral impurities in the form of stones, fall into the green mass. Having hit the crusher stones lead to damage to parts of the crushing mechanism, an accident and even an explosion. Clearing straw from impurities in agriculture is carried out on pneumatic separating machines [3]. But in the technical literature there is no data available to the separation of mineral impurities from the AHRC. As a result of the experiments, it was found that leaves and stalks can be separated by air from large stones, and the separation ofrods from stones is complicated. Under the influence of air flow, the rods are rotated along the pneumatic separating canal and unfolded by a long axis in parallel with the air flow, which leads to a decrease in the area of the midel section and to the reduction of the aerodynamic resistance. Therefore, to provide the required force acting on the core from the air stream, they increase the air velocity, which causes the capture and joint movement of the stones. To improve the separation process of the AHRC from the stones, it is necessary to develop a nutritional mechanism of the separator, in which to predict the possibility of orientation of the rods in the pneumocaps to the long axis across the air flow. This will enable you to reduce the air velocity required for separation and increase the difference in aerodynamic forces acting on the stones and rods. Accordingly, at the same time, the energy intensity of the pneumatic separation process will decrease and the efficiency of separating the AHRC from the stones increases. The separation of small stones smaller than 3 mm only by air is impossible, since they are picked up by the air flow that moves at the speed necessary for separating the stems (7.5...12.5 m/s). For the separation of small stones, it is proposed to use grid separators with combined air purge. For the complete separation of mineral impurities from corn cores, it is recommended to use hydro-separators.
Management Costs as a Manifestation of Transaction Costs in Hierarchical Structures for the Coordination of Production and Exchange Processes
Authors: Plichta Jarosław
Published: February 2019

According to the assumptions of representatives of institutional economics, enterprises as market institutions exist due to the existence of transaction costs in the processes of market exchange. The hierarchical structures of enterprises limit their occurrence and thus they are by definition more effective than the coordination of exchange by a market mechanism. The creation and maintenance of such structures also bring about costs. These are generally management costs, some of which are transaction costs. They result from imperfections of internal processes, information asymmetry, the division and establishment of property rights, opportunistic behaviour or specific resources involved in these processes. The article looks at the problems of management costs perceived from the institutional point of view, as transaction costs and an indication of the broad applicability of this approach, especially in the context of new phenomena and processes based mainly on modern technologies and the mechanisms of co-creating value. The considerations are of a conceptual character and are based on the achievements of various scientific disciplines.
Społeczna odpowiedzialność biznesu jako nowa forma dialogu w obszarze działań gospodarczych
Authors: Filek Janina
Published: February 2019

Built on a philosophical and social analysis, the paper’s thesis is that corporate social responsibility is a new form of social dialogue. To support the thesis, the features of social communication (on the level of colloquial language), features of philosophical dialogue, and features of corporate social responsibility dialogue are compared. Following the presentation of the corporate social responsibility dialogue, the anthropological, economic and social advantages of a dialogue between companies and their stakeholders is described. One conclusion the analysis led to is that, in the current social-economic situation, further economic development has been increasingly dependent on a company’s dialogue with its stakeholders.  Further benefits a company can derive from conducting a responsible dialogue with stakeholders are also indicated.
Poczucie szacunku pracowników jako predyktor zaangażowania organizacyjnego
Authors: Szczygieł Alicja
Published: February 2019

Current management of human capital is not limited to the motivation of workers to perform their duties. Companies strive to build capital with employees who are both motivated and involved in the organisation. A high level of commitment obviously brings organisations numerous benefits, and although the issue has been discussed for years, it remains a source of scientific interest and business. Involved employees are loyal to their companies beyond the scope of their duties, and act upon their own initiative, often contributing to improved organisational efficiency. The article pays particular attention to the need for employees to feel respect from supervisors and its importance for affective, normative and lasting engagement.
Elastyczność rynku pracy w Polsce w świetle teorii optymalnych obszarów walutowych
Authors: Kawalec Marcin
Published: February 2019

Labour market flexibility is understood as the ability of the market to smoothly adapt to changing economic conditions. To function smoothly and be flexible, the labour market must be able to quickly respond to the demand for labour and changes taking place in the economy. In the context of the theory of optimum currency areas, labour market flexibility plays a greater role as a substitute for flexibility of exchange rates in reducing shocks to the monetary union. The aim of this work is to analyse the current level of labour market flexibility in Poland, in particular in the context of the optimum currency area theory criteria. The most important conclusion from the analysis is that Poland’s labour market is too inflexible, and is therefore an effective alternative to exchange rate flexibility in macroeconomic adjustments.

Repertório vocal de Hylodes phyllodes (Amphibia, Anura, Hylodidae)
Authors: Hartmann Marília T. , Hartmann Paulo A. , Haddad Célio F.B.
Published: February 2019

Hyllodes phyllodes é um anfíbio diurno, que ocorre em córregos de montanha associados à Floresta Atlântica. Neste estudo, são caracterizados cinco tipos de vocalizações de Hylodes phyllodes relacionadas com o comportamento social desta espécie: dois tipos de canto de anúncio, canto de corte, canto territorial e canto de intervalo de briga. O estudo foi realizado entre janeiro de 2001 e novembro de 2002 em córregos na Mata Atlântica, dentro da área do Núcleo Picinguaba, Parque Estadual da Serra do Mar, no Município de Ubatuba, Estado de São Paulo. As observações foram realizadas em vários horários do dia, totalizando 80 horas de observações e gravação de 22 espécimes. O canto de anúncio descrito neste estudo apresentou pequenas diferenças em relação ao canto descrito originalmente, mas estas diferenças provavelmente são resultado de condições ambientais e/ou características comportamentais dos indivíduos gravados em Picinguaba e Boracéia. Adaptações na vocalização de espécies diurnas que vivem em riachos de correnteza permitem a comunicação sonora em um canal livre do barulho d'água, deste modo, os cantos de H. phyllodes têm freqüência dominante acima do barulho da correnteza, ou seja, maior que 3,5 kHz. Este estudo identifica H. phyllodes como a espécie com o repertório vocal mais rico do gênero.
Larval development of Notolopas brasiliensis Miers, 1886 (Brachyura: Majoidea: Pisidae) described from laboratory reared material and a reappraisal of the characters of Pisidae
Authors: Santana William , Marques Fernando P.L. , Fransozo Adilson , Bertini Giovana
Published: February 2019

The complete larval stages of Notolopas brasiliensis are described from laboratory reared material, with emphasis on the external morphological features of Majoidea, and compare the morphology of N. brasiliensis with other genera of Pisidae. Larval development of N. brasiliensis consists of two zoeal stages and one megalopa. The duration mean of each zoeal stage was 4.2 ± 1.0 days for Zoea I and 3.8 ± 0.7 days for Zoea II, the megalopa instar appearing 8.1 ± 0.4 days after hatching. The characters previously used to define larval forms of Pisidae are either symplesiomorphic or potentially highly homoplastic. As well, was observed that there are no common sets of larval characters that would define Pisidae nowadays. However, was showed that only a combination of characters could differentiate Notolopas from other pisid genera.

Female monopolization and paternity assurance in South American crickets (Orthoptera, Grylloidea): mating plugs, extra claspers and forced copulation
Authors: Mello Francisco de A.G. de
Published: February 2019

This paper describes the first three cases in which male crickets monopolize females by means of mating plugs. The origin of the plugs vary among the cases (i.e., they are not homologous). Female monogamy is assured by the permanent presence of the plug attached to their genitalia after first mating, while males are potentially polygamous. The presence of an additional clasping structure and the occurrence of forced copulation are also described.

Oxylopsebus brachypterus: a new genus and species of Oxycoleini (Coleoptera, Cerambycidae, Cerambycinae) from Bolivia
Authors: Clarke Robin O. S.
Published: February 2019

Oxylopsebus brachypterus new genus and species from humid tropical forest, Department of Santa Cruz, Bolivia is described and illustrated. Although with reduced elytra, the genus is placed in Oxycoleini based on the following characters: female urosternites modified, the first as long as the second to fourth together, the second with a brush for covering the eggs with detritus after being laid; the male with six visible urosternites, the first twice as long as the second; eyes with superior lobes; prothorax divergent behind, disc of pronotum with calli; procoxal cavities closed behind. Oxylopsebus gen. nov. would seem to fall between the Oxycoleini and Psebiini and be less closely related to the Obriini and Luscosmodicini, the four tribes in which the females have modified urosternites (the " Obriini group" sensu Martins, 2003). All the specimens were netted as they visited flowers of the vine Serjania lethalis (Sapindaceae).

É apresentada uma revisão histórica dos inventários ornitológicos conduzidos na Chapada dos Guimarães, centro-oeste do Brasil. A avifauna da região é caracterizada a partir de uma revisão crítica de todas as listas de espécies produzidas por várias gerações de ornitólogos, espécimes depositados em museus e meticulosos trabalhos de campo. Especial atenção foi dada às publicações de J.A. Allen, baseadas na monumental coleção preparada por H.H. Smith e sua esposa no final do século XIX. A avifauna da região é típica do Cerrado, abrigando também espécies amazônicas. Um total de 393 espécies de aves é listado para a região, sendo outras 52 espécies citadas pela literatura consideradas de ocorrência improvável baseado nos critérios restritivos adotados. Vinte e quatro espécies coletadas pelos Smith não foram mais registradas para a região. Seis destas espécies são campestres e bastante sensíveis a alterações antrópicas, enquanto que outras três são perseguidas pelo comércio ilegal de aves. Estas espécies provavelmente se encontram extintas na região. Sete outras espécies associadas a corpos hídricos, e duas de distribuição predominantemente Amazônica, eram provavelmente raras na região, mesmo em tempos históricos, principalmente devido à falta de hábitat adequado. Seis outras são normalmente raras, podendo ter passado despercebidas. São apresentados o primeiro registro documentado de Caprimulgus longirostris para o Mato Grosso e o segundo registro de Pipraeidea melanonota para o estado. Também são discutidos os registros de outras espécies raras na região, tais como Ictinia mississipensis, Buteo melanoleucus, Harpia harpyja, Megascops usta, Asio flammeus, Berlepschia rikeri, Euscarthmus rufomarginatus, Xenopsaris albinucha e Poospiza cinerea.
First assessment of the avifauna of Araucaria forests and other habitats from extreme southern Minas Gerais, Serra da Mantiqueira, Brazil, with notes on biogeography and conservation
Authors: Vasconcelos Marcelo Ferreira de , D'Angelo Neto Santos
Published: February 2019

The avifauna of the Araucaria forests in the higher reaches of the Serra da Mantiqueira massif is little known and poorly documented. This region is recognized as an important area of differentiation of birds in southeastern Brazil. Here, we present the first ornithological survey of the Araucaria forests and associated habitats in the mountains of extreme southern Minas Gerais state, near the southern tip of the Serra da Mantiqueira. The study area comprises the Serra do Juncal region and several adjacent sites, located in the municipalities of Gonçalves and Camanducaia. We recorded 206 bird species, of which 57 (27.7%) are endemic to the Atlantic forest. Several records represent the first specimens for Minas Gerais, in the hinterlands of Serra da Mantiqueira, proving that many Atlantic species also occur in the intern most slope of this mountain range. Examples are: Dysithamnus xanthopterus, Chamaeza ruficauda, Leptasthenura setaria, Heliobletus contaminatus, Hemitriccus obsoletus, Phylloscartes difficilis, Piprites pileata, Poospiza thoracica, and Cacicus chrysopterus. The region is also a previously unknown area of sympatry of other closely related species: Scytalopus notorius and S. speluncae, Lepidocolaptes squamatus and L. falcinellus, and Basileuterus culicivorus and B. hypoleucus. Both species of Lepidocolaptes and Basileuterus hybridize in the region. We also comment on the avifauna conservation, which have been threatened by eco-tourism, building of new styles of houses, domestic animals, forest fragmentation, and plantations.

Published: February 2019

Termite mounds are known to offer refuge and microhabitats to a great variety of invertebrates and vertebrates. In the valley of the upper Tocantins River, within areas of influence of hydroelectric power plants 4,000 termite mounds were surveyed to evaluate the diversity of amphibians and reptiles using these environments. Surveys in termite mounds from two other areas (Corumbá River and Araguaia River basins) were used for comparative purposes. The results for termitaria in the upper Tocantins river valley revealed nine families, 13 genera, and 25 species of amphibians, and 16 families, 32 genera, and 47 species of squamate reptiles. Compared to a general herpetofaunal list of the region, the data indicate that between 30.6% and 56.8% of the species use termitaria.

Comparative morphology among representatives of main taxa of Scaphopoda and basal protobranch Bivalvia (Mollusca)
Authors: Simone Luiz Ricardo L.
Published: February 2019

This study deals with detailed morphology and anatomy of 4 species of Scaphopoda and 5 species of protobranch Bivalvia. Both classes are traditionally grouped in the taxon Diasoma, which has been questioned by different methodologies, such as molecular and developmental. This study is developed under a phylogenetic methodology with the main concern in performing it in an intelligible and testable methodology. The analyzed Scaphopoda species came from the Brazilian coast and belong to the family Dentaliidae [(1) Coccodentalium carduus; (2) Paradentalium disparile] and Gadiliidae; [(3) Polyschides noronhensis, n. sp. from Fernando de Noronha Archipelago; (4) Gadila braziliensis]. These species represent the main branches of the class Scaphopoda. From protobranch bivalves, representatives of the families Solemyidae [(5) Solemya occidentalis, from Florida; S. notialis, n. sp. from S.E. Brazil], Nuculanidae [(6) Propeleda carpentieri from Florida], and Nuculidae [(7) Ennucula puelcha, from south Brazil] are included. These species represent the main branches of the basal Bivalvia. The descriptions on the anatomy of S. occidentalis and of P. carpentieri are published elsewhere. The remaining are included here, for which a complete taxonomical treatment is performed. Beyond these species, representatives of other taxa are operationally included as part of the ingroup (indices are then shared with them), as a procedure to test the morphological monophyly of Diasoma. These taxa are: two lamellibranch bivalves [(8) Barbatia - Arcidae; (9) Serratina - Tellinidae; both published elsewhere;, and Propilidium (10) Patellogastropoda, and (11) Nautilus, basal Cephalopoda, based on basal taxa. The effective outgroups are (12) Neopilina (Monoplacophora) and (13) Hanleya (Polyplacophora). The phylogenetic analysis based on morphology revealed that the taxon Diasoma is supported by 14 synapomorphies, and is separated from Cyrtosoma (Gastropoda + Cephalopoda). Although they are not the main goal of this paper, the taxa Scaphopoda and Bivalvia are supported by 8 and by 7 synapomorphies respectively. The taxon Protobranchia resulted paraphyletic. Both scaphopod orders resulted monophyletic. The obtained cladogram is: ((((Coccodentalium carduus - Paradentalium disparile) (Polyschides noronhensis - Gadila brasiliensis)) ((Solemya occidentalis - S. notialis) (Propeleda carpenteri (Ennucula puelcha (Barbatia cancellaria - Serratina capsoides))))) (Propilidium curumim - Nautilus pompilius - Lolliguncula brevis)).

Published: February 2019

A Estação Ecológica dos Caetetus possui um dos maiores remanescentes de mata estacional semidecídua ainda presentes no Estado de São Paulo. Poucos estudos foram realizados nessa localidade, extremamente importante no que diz respeito às aves da Mata Atlântica do interior do Estado. Para caracterizar a avifauna da estação com dados recentes e contribuir com novos registros, foi realizado um levantamento da avifauna utilizando-se o método de Pontos de Escuta entre outubro de 2005 e dezembro de 2006. Foram registradas 226 espécies enquanto diversos autores registraram outras 68, para um total de 293. Muitas espécies são endêmicas da Mata Atlântica ou do Cerrado e algumas são ameaçadas no Estado, justificando a existência dessa unidade de conservação e provando a necessidade de inventários em longo prazo e da preservação de fragmentos de mata estacional semidecídua nativa.

Published: February 2019

Although studies on drosophilid (Diptera, Drosophilidae) assemblages have become relatively abundant in the past decades, many environments remain to be searched. The present study investigates the composition, the species abundances and the richness of the drosophilid assemblages in two localities of the municipality of Cruz Alta, northwestern region of the state of Rio Grande do Sul, a point of contact between the biomes Atlantic Forest and Pampa: (i) an urban area (2007), constituted by a domestic orchard with Citrus trees, and (ii) a forested area, in Centro de Educação, Pesquisa e Proteção Ambiental - CEPPA (2008/2009), of Universidade de Cruz Alta, located in a fragment of riparian forest. Collections were conducted using fermented banana-baited traps and repeated periodically. A total of 7,428 individuals were caught, belonging to two subfamilies, six genera and 53 species. In the urban area, 22 species were found, from two genera (N = 2,421), while in the forested area 46 species were found, from six genera (N = 5,007). Six exotic species were found, markedly more abundant in the urban area, where they corresponded to 95% of the specimens, in comparison to 50% in the forest. Between the Neotropical species, the most common were Drosophila maculifrons Duda and D. polymorpha Dobzhansky & Pavan. Only D. simulans Sturtevant was captured in all samples in both localities. The present survey represents the first records for the state of Rio Grande do Sul of the D. canalinea and D. virilis species groups and the species D. arassari Cunha & Frota-Pessoa, D. fuscolineata Duda, D. nigricruria Patterson & Mainland, D. papei Bächli & Vilela, D. senei Vilela, D. trifilum Frota-Pessoa, D. virilis Sturtevant, Leucophenga maculosa (Coquillett) and Rhinoleucophenga obesa (Loew). Furthermore, it also represents the first record for the state of the genera Amiota Loew, Leucophenga Mik and Rhinoleucophenga Hendel and of the subfamily Steganinae. So, the present survey raises the number of drosophilid species recorded for the state from 66 to 75, the number of genera from five to eight, and subfamilies from one to two.

Authors: Santos-Silva Antonio , Martins Ubirajara R , Tavakilian Gérard L
Published: February 2019

Polyrhaphis Audinet-Serville, 1835, gênero de Lamiinae distribuído entre o México e América do Sul (excluindo o Chile e abaixo da latitude 35°S), é revisado. Três espécies novas são descritas: P. baloupae, procedente da Guiana Francesa; P. lanei, proveniente do Brasil (Amazonas e Pará); e P. peruana, do Peru. Duas espécies são sinonimizadas: P. testacea Lane, 1965 (= P. gracilis Bates, 1862) e P. paraensis [= P. papulosa (Olivier, 1795)]. É designado neótipo para P. papulosa. A autoria de P. horrida [= P. spinosa (Drury, 1773)] é discutida. Cerambyx armatus Voet (1778?) é considerado um nome inválido e Lamia armiger Schöenherr, 1817 (= Polyrhaphis armiger) o nome válido dessa espécie. Polyrhaphis spinipennis Laporte, 1840, é excluída da fauna da Colômbia. Novos registros de distribuição: P. argentina Lane, 1978, para o estado de São Paulo (Brasil); P. batesi Hovore & McCarty, 1998, para o Equador; P. belti Hovore & McCarty, 1998 para o Equador e Colômbia; P. gracilis Bates, 1862, para a guiana Francesa; e P. turnbowi Hovore & McCarty, 1998, em dúvida, para o Peru. É apresentada chave para as espécies do gênero.
Geographical and seasonal distributions of the seedeaters Sporophila bouvreuil and Sporophila pileata (aves: Emberizidae)
Authors: Machado Érika , Silveira Luís Fábio
Published: February 2019

Many species in the genus Sporophila are migratory. Migration patterns, while poorly studied, may be influenced by seed production which can be very seasonal in some regions. The distribution of S. bouvreuil extends from the Amazon and Suriname south through a large part of the open regions of Brazil. Sporophila pileata, on the other hand, is found in southeastern and southern Brazil as well as Argentina and Paraguay. Both of these species migrate, but their movement patterns are poorly known. To better understand the geographical and the seasonal distributions of S. bouvreuil and S. pileata, we grouped the records into two categories: the breeding season (September to March) and the putative migration season (April to August). We found two areas of sympatry between S. bouvreuil and S. pileata in the Brazilian states of Minas Gerais and São Paulo. For S. bouvreuil we suggest that populations that breed in the Amazon migrate to the Cerrado or Caatinga, where they will encounter resident populations of the same species. These resident populations may take part in short distance migrations. Sporophila pileata, on the other hand, occur in the Cerrado and open areas within the Atlantic Forest and it is not yet possible to determine migratory tendencies or destinations in the non-breeding season.

Redescription of Hanleya brachyplax (Polyplacophora, Hanleyidae) from the south-southeastern Brazilian coast
Authors: Jardim Jaime A. , Simone Luiz Ricardo L.
Published: February 2019

Hanleya brachyplax Simone & Jardim in Rios, 2009 is described in detail. The species occurs off the southeastern and south coast of Brazil (São Paulo and Santa Catarina states) in depths from 250 to 408 m. It differs from its congeners in having uniform white valves; wide intermediate valves; the tail valve with straight profile in the antemucronal area, and a concave postmucronal surface; and a cream-colored girdle, covered by non-articulated spines. An anatomical investigation was also performed, showing the main muscle groups; the presence of gills in the posterior third of the pallial groove; auricle with six orifices; a very flat kidney, restricted to the posterior half of the animal; and a simple esophageal region. The odontophore has a single pair of long cartilages. The buccal musculature is also described.
Padrões espaciais na distribuição de abelhas Euglossina (Hymenoptera, Apidae) da região Neotropical
Authors: Sydney Nicolle V. , Gonçalves Rodrigo B. , Faria Luiz R.R.
Published: February 2019

Abelhas das orquídeas (Apini, Euglossina) apresentam distribuição principalmente Neotropical, com cerca de 200 espécies e cinco gêneros descritos. Muitos levantamentos locais de fauna estão disponíveis na literatura, mas estudos comparativos sobre a composição e distribuição dos Euglossina são ainda escassos. O objetivo deste estudo é analisar os dados disponíveis de 29 assembleias a fim de entender os padrões gerais de distribuição espacial nas áreas amostradas ao longo do Neotrópico. Métodos de ordenação (DCA e NMDS) foram utilizados para descrever os agrupamentos de assembleias de acordo com as ocorrências de abelhas das orquídeas. As localidades de florestas da América Central e da Amazônia formaram grupos coesos em ambas as análises, enquanto as localidades de Mata Atlântica ficaram mais dispersas nos gráficos. Localidades na margem leste da Amazônia aparecem como áreas de transição características entre esta sub-região e a Mata Atlântica. As análises de variância entre o primeiro eixo da DCA e variáveis selecionadas apresentaram valores significantes quanto à influência dos gradientes de latitude, longitude e precipitação, bem como das sub-regiões biogeográficas nos agrupamentos das assembleias. O padrão geral encontrado é congruente com os padrões biogeográficos previamente propostos para a região Neotropical. Os resultados do DCA auxiliam ainda a identificar, de forma independente, os elementos das faunas de cada uma das formações vegetais estudadas.
Nuevos registros de squamata (reptilia) para el pleistoceno superior del norte de la provincia de Buenos Aires, Argentina
Authors: Agnolin Federico , Jofré Guillermo
Published: February 2019

En el presente artículo son reportados ejemplares de diversos taxones de reptiles escamados fósiles procedentes de la base de la Formación Luján (Pleistoceno Superior), en la localidad fosilífera de Merlo, provincia de Buenos Aires, Argentina. Entre los ejemplares registrados se reconoce el primer registro fósil para el género y especie Anops kingii (Amphisbaenidae); asimismo se reporta la presencia de especies indeterminadas de los géneros Homonota (Gekkonidae) y Liolaemus (Liolaemidae). La asociación conjunta de estos tres taxones hoy en día no se encuentra representada en el norte de la provincia de Buenos Aires, siendo la región geográficamente más cercana en donde encuentran una superposición en su distribución el Partido de Balcarce, ubicado en el extremo Sureste de la provincia y alejado unos 600 kilómetros al sur de la localidad fosilífera de Merlo. La presencia conjunta de estos tres reptiles se encuentra de acuerdo con la posible existencia de un pulso árido y frío, tal como ha sido propuesto con anterioridad para porción más inferior del Pleistoceno Superior en la provincia de Buenos Aires.

Authors: Deler-Hernández Albert , Santos-Silva Antonio
Published: February 2019

Three species of Parandrinae are recognized from Cuba, all belong to Birandra (Yvesandra) Santos-Silva & Shute, 2009: B. (Y.) cubaecola (Chevrolat, 1862); B. (Y.) cribrata (Thomson, 1861); and B. (Y.) latreillei Santos-Silva & Shute, 2009. The latter, confused with the former by Zayas (1957, 1975) is confirmed as a common species on the island. Birandra (Y.) cubaecola is excluded from the fauna of Puerto Rico; B. (Y.) cribrata is also excluded from Puerto Rico as well as Hispaniola.
