Subterranean Habitat

In this paper, we describe three new Eukoenenia species from specimens collected in limestone caves in the northern region of the Minas Gerais state, Brazil. These species present different degrees of adaptation to the subterranean habitat, with Eukoenenia magna sp. nov., with 6 blades on lateral organs and body ratios very close to other troglobitic species, being the most troglomorphic among them. This species is morphologically very similar to the Brazilian troglobites E. navi, E. eywa and E. neytiri. Eukoenenia lundi sp. nov. and Eukoenenia jequitai sp. nov. are probably closely related species due to their substantial morphological resemblance. These two species are closer to E. virgemdalapa among the Brazilian species described to date. We provide a table summarizing the main diagnostic characters of the three species herein described and those of the Brazilian congeners to facilitate morphological comparisons.

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.

History Of

Abstract SARS-CoV-2 has spread rapidly around the world, with Brazil currently considered an epicenter of the pandemic. The northern region of the country has the highest incidence and mortality rates. This study aimed to investigate information about the evolutionary history of epidemic spread and genetic aspects of strains isolated on the Western Amazon, in the State of Rondônia, Brazil. It was possible to detect a total of 22 mutations. Some of these alterations may possibly be related to effects on transmissibility, the fidelity of RNA replication, the ability of cancer patients to respond to infection, beyond a mutation that emerged after the introduction of SARS-CoV-2 in Rondônia. At least two events of introduction were detected, corresponding to the B.1 and B.1.1 European lineages. An introduction was observed possibly through Argentina, where strains originated that circulated in the Minas Gerais and Ceará Brazilian states, prior to Rondônia (B.1.), as well as through the Minas Gerais state and the Federal District, which gave rise to strains that spread to Rondônia, from the capital to more rural parts of the state (B.1.1.). The findings show the need to monitor the genetic epidemiology of COVID-19, in order to surveil the virus’s evolution, dispersion and diversity.

Crickets of the genus Endecous (Orthoptera: Grylloidea: Phalangopsidae) are frequently found in caves, in some cases presenting strictly subterranean lifestyle. In addition to the morphological diagnostic characters of the group, bioacoustic and karyotype, also help on delimiting species. Here, we describe two new sympatric species of this genus, which occur in the largest cave of Minas Gerais state, Brazil, using the morphology of phallic complex, the courtship song and karyotype. Moreover, we discuss the criteria used, the troglomorphisms for this genus, as well as hypothesis on the speciation process involving these species.

Species Being

Chemotaxis between gametes particularly of the Fucaceae is discussed and techniques for its detection described. Cell-free preparations of Fucus serratus and F. vesiculosus eggs have been obtained which exert a chemotactic attraction on the sperms of F. serratus , F. vesiculosus and F. spiralis , the same chemotactic mechanism among these closely related species being indicated. The chemotactic principle is easily expelled from aqueous solution by a stream of inert gas, and may be recovered in a cooled receiver; it seems therefore to be a simple compound. Various arylacetic acids have a marked effect on the Fucus sperms studied but this effect is distinct from true chemotaxis and is not related to the plant hormone or herbicide activities of the responsible acids.

Copaifera langsdorffii specie occurs throughout Brazil and is of great economic importance, mainly due to its production of oil-resin used for various pharmacological purposes. The objective of this study was to analyze the morphometric relationships in C. langsdorffii stand in northern region of Minas Gerais state, Brazil. Twenty trees were randomly sampled and were measured: stem circumference at 1.3 m height, total height (Ht) and crown diameter (CD). Morphometric indices were estimated. Correlations between dendrometric and morphometric variables were obtained through the Pearson matrix. The morphometric relations of crown proportion (CP), crown area (CA), formal of crown (FC), degree of slenderness (DS), salience index (SI), coverage index (CI) and vital space (VS) presented values of 15.26%, 25.06 m², 1.47, 16.35, 21.70, 0.47 and 7.01, respectively. Strong positive correlations were found in: diameter at breast height (DBH) in relation to CD and CA; Ht with crown proportion (CP) and DS; the formal of crown (FC) with the CI and VS, and between the CI and VS. The morphometric indices made it possible to understand the few magnitude of stand variation. The species can be characterized as facilitating management.

The Zona da Mata region is located in southeastern Minas Gerais State, Brazil with fauna and flora diversified, including herbivorous insects and Solanaceae plants. Ithomiinae caterpillars were observed damaging tree of Solanum granuloso-leprosum Dunal (Solanaceae), used for different purposes and abundant in secondary forest. The objective of this study was to identify defoliating caterpillars of S. granuloso-leprosum at the campus of Universidade Federal de Viçosa (UFV) in Viçosa, Minas Gerais State, Brazil and review host plants of Mechanitis polymnia L., 1758 (Lepidoptera: Nymphalidae). Thirteen caterpillars found damaging a tree of S. granuloso-leprosum at the campus of UFV were collected and maintained in the Laboratório de Controle Biológico de Insetos (LCBI) from UFV until adult emergence. These caterpillars were of two species, being ten of the first and three of the second species. Adult specimens of the latter species were identified as Ithomia lichyi lichyi D'Almeida, 1939 (Lepidoptera: Nymphalidae) in the Departamento de Zoologia of Universidade Federal do Paraná (UFPR) in Curitiba, Paraná State, Brazil and of the group of ten caterpillars as Mechanitis polymnia casabranca Haensch, 1905 (Lepidoptera: Nymphalidae) in the Museu de Zoologia of Universidade de São Paulo (USP) in São Paulo State, Brazil. This is the first report of M. polymnia casabranca and I. lichyi lichyi together damaging plant of S. granuloso-leprosum in the Zona da Mata region of Minas Gerais State, Brazil and 57 plants are recorded as host of M. polymnia.

Aplopabaksis filum (Goeze, 1782), A. clerci Yamaguti, 1935, and A. brachyphallos (Krabbe, 1869) are closely related species that are distinguishable mainly on anatomical characters, their scolex structures being remarkably uniform both in size and form. This opportunity is taken of defining the main diagnostic characters of the three species from an investigation of material collected in the Aberystwyth area of Wales.
