Microtheca spp. (Coleoptera: Chrysomelidae) are insect pests primarily related to Brassicaceae crops. In the State of Rio Grande do Sul (RS), southern Brazil, they are found on forage turnip, Raphanus sativus L. var. oleiferus Metzg., which is commonly grown during fall/winter seasons. This work reports the predation of Microtheca spp. larvae by Toxomerus duplicatus Wiedemann, 1830 (Diptera: Syrphidae) larvae, on forage turnip crop, in Santa Maria, RS. This register provides new information about Microtheca spp. natural enemies in Brazil, which might be a new option for integrate pest management of these species.

O objetivo deste trabalho foi avaliar as relações entre caracteres de nabo forrageiro (Raphanus sativus L.) e de tremoço branco (Lupinus albus L.), e identificar caracteres para a seleção indireta. Foi conduzido um experimento com nabo forrageiro e outro com tremoço branco, em Santa Maria, Estado do Rio Grande do Sul (latitude 29°42'S, longitude 53°49'W e 95m de altitude). Na colheita, foram mensurados a altura de planta, o diâmetro de caule, o número de folhas e as massas verde e seca de parte aérea em 300 plantas de nabo forrageiro e a altura de planta, o diâmetro de caule, o número de vagens e as massas verde e seca de parte aérea em 400 plantas de tremoço branco. Foi investigada a relação entre os caracteres por meio de diagramas de dispersão e análises de correlação e de trilha. Na cultura de nabo forrageiro, o diâmetro de caule tem relação linear positiva com as massas verde e seca e pode ser utilizado para seleção indireta. Na cultura de tremoço branco, o número de vagens por planta tem relação linear positiva com as massas verde e seca e pode ser utilizado para seleção indireta.

RESUMO: A produção mundial de noz-pecã Carya illinoinensis (Juglandaceae) é liderada pelos Estados Unidos. No Brasil, em especial no Rio Grande do Sul, houve uma expansão da área plantada com a cultura nos últimos anos. No entanto, faltam pesquisas relacionadas à entomofauna associada à noz-pecã, bem como práticas culturais que auxiliem no Manejo Integrado de Pragas, mesmo havendo uma expansão da cultura. Assim, o presente estudo objetivou avaliar a fauna de artrópodes na copa de plantas de C. illinoinensis, submetido a diferentes manejos de solo, em Santa Maria, Rio Grande do Sul, Brasil. Para tanto, utilizou-se delineamento experimental de blocos ao acaso, com cinco blocos e quatro tratamentos: plantio em cova pequena, com 20 × 60 cm (Sp); utilização de subsolador mais grade niveladora e cova pequena (Ssp); utilização de enxada rotativa e cova pequena (Tsp); e plantio em cova grande, com 40 × 60 cm (Lp). De novembro de 2014 a maio de 2015, foram coletadas 7.617 espécimes nas copas de árvores jovens de nogueira-pecã. Foram identificados 150 grupos taxonômicos, sendo Coleoptera a ordem com maior riqueza de espécies. Monellia caryella (Hemiptera: Aphididae) apresentou elevada densidade. Foram registrados os inimigos naturais himenópteros parasitoides e Coccinellidae. Conclui-se que a artropodofauna em copas de plantas jovens de nogueira-pecã apresenta diversidade similar entre os tratamentos e predomínio de M. caryella nas áreas avaliadas.

The ‘rauisuchians’ are a group of Triassic pseudosuchian archosaurs that displayed a near global distribution. Their problematic taxonomic resolution comes from the fact that most taxa are represented only by a few and/or mostly incomplete specimens. In the last few decades, renewed interest in early archosaur evolution has helped to clarify some of these problems, but further studies on the taxonomic and paleobiological aspects are still needed. In the present work, we describe new material attributed to the ‘rauisuchian’ taxonPrestosuchus chiniquensis, of theDinodontosaurusAssemblage Zone, Middle Triassic (Ladinian) of the Santa Maria Supersequence of southern Brazil, based on a comparative osteologic analysis. Additionally, we present well supported evidence that these represent juvenile forms, due to differences in osteological features (i.e., a subnarial fenestra) that when compared to previously described specimens can be attributed to ontogeny and indicate variation within a single taxon of a problematic but important osteological structure in the study of ‘rauisuchians.’

A Triassic taphoflora identified in the Central Region of the State of Rio Grande do Sul, southern Brazil, represents an important biostratigraphic stage in the paleofloristic succession of the Paraná Basin. This megafloristic association is composed of compressed leaves, fronds and seeds of a “Dicroidium Flora” and shows a predominance of the Dicroidium genus, with several species, and other important taxa like Neocalamites sp, Cladophlebis sp, Tetraptilon aff, heteromerum, Ginkgoites Antarctica, Sphenobaiera sp, Podozamites sp, Nilssonia sp, Pteruchus sp and Carpolithus sp. Taking into account the stratigraphical distribution of different species of the Dicroidium genus, a biostratigraphic framework was established. The biostratigraphical position of this Triassic flora was established by comparison with Triassic floras from Argentina, South Africa and Australasia. Considering that the recognition of this Dicroidium Flora was based on limited outcrops belonging to one lithostratiphic level (Santa Maria Formation – Passo das Tropas Facies), it was impossible to establish a formal biostratigraphic zonation. Instead, at present time, an informal floristic interval, named “Dicroidium odontopteroides Flora” is proposed (Late Anisian to Late Ladinian, Middle Triassic).

A determinação das taxas de infiltração de água no solo é de fundamental importância, pois além de determinar a recarga de aquíferos estima a vulnerabilidade a contaminação a qual o mesmo está sujeito. Com base nisso o presente trabalho tem por objetivo determinar o índice de infiltração de água no solo pelo método DRASTIC na bacia hidrográfica do rio Vacacaí-Mirim, no estado do Rio Grande do Sul. Para a determinação desses índices, seguiu-se a metodologia descrita por Oliveira e Ferreira (2002), onde as análises para os parâmetros físicos foram obtidos no laboratório de física do solo da Universidade Federal de Santa Maria, campus de Frederico Westphalen-RS. Os índices de facilidade a infiltração nos anos de 2010 e 2011 variaram de 10 (áreas pouco fissuradas) a 30 (áreas com altas perfurações). Com relação as áreas de infiltração máxima, no ano de 2010, 24 % da área da bacia apresentou tal condição, já para o ano de 2011, esse percentual caiu para 18,55 %. Com base nisso, a metodologia se mostra interessante para a determinação das taxas de infiltração de água na bacia hidrográfica do rio Vacacaí-Mirim. As áreas que mais se destacaram com as taxas de infiltração máxima localizam-se nas várzeas da bacia hidrográfica, onde predominam o cultivo de arroz, sendo assim é de fundamental importância a preservação de tais áreas com vista a manutenção da qualidade da água subterrânea no local.

Subjective Synonym

Huene (1935) first reported dicynodonts from the Triassic Santa Maria Formation of southern Brazil. Most common are specimens of Dinodontosaurus from localities near Chiniquà (Chiniquà local fauna) and near Candelaria (Candelaria local fauna) in the state of Rio Grande do Sul. The other Middle Triassic dicynodont found near Chiniquà is the huge (about 3 m body length) Stahleckeria potens, and an equally large Middle Triassic dicynodont, Barysoma lenzii, is known from near Candelaria. A fourth, supposed Santa Maria Formation dicynodont, Jachaleria candelariensis (Araújo and Gonzaga, 1990), is actually from a younger, Upper Triassic, horizon of the Caturrita Formation near Candelaria (Bonaparte, 1982). Here, I argue that Barysoma lenzii is a junior subjective synonym of Stahleckeria potens and discuss the biochronological significance of this synonymy.

This research aims to verify the municipalities where it might be interesting to invest in a local beef production in the State of Rio Grande do Sul (RS), southern Brazil. The data analyzed combine the cattle units slaughtered and the estimated beef consumption in each municipality. These indicators were used to identify the capacity of each location to meet the local beef demand. This data were associated to the map of RS by the Quantum GIS 1.8 Lisboa software. The most prominent regions were located at the western frontier, at the southeast Campanha, and at the northeast mountain region of the State. The cattle units slaughtered produced at the municipalities of Aceguá, Pedras Altas, Machadinho, São Valentim, Quatro Irmãos and Sagrada Família is very high, surpassing the municipality’s capacity to absorb it. On the other hand, many municipalities have sufficient productions or little surplus to attend the local beef demand, such as Alegrete, in which a local beef production might benefit a higher number of small producers, but other municipalities also seem to have potential for assisting familiar farmers with this strategy such as Dom Pedrito, Bagé, Santa Maria and Pelotas.

We report here on a new prozostrodontian cynodont, Botucaraitherium belarminoi gen. et sp. nov., from the Late Triassic Riograndia Assemblage Zone (AZ) of the Candelária Sequence (Santa Maria Supersequence), collected in the Botucaraí Hill Site, Candelária Municipality, state of Rio Grande do Sul, Brazil. The new taxon is based on a single specimen (holotype MMACR-PV-003-T) which includes the left lower jaw, without postdentary bones, bearing the root of the last incisor, canine and four postcanines plus one partial crown inside the dentary, not erupted, and two maxillary fragments, one with a broken canine and another with one postcanine. The features of the lower jaw and lower/upper postcanines resemble those of the prozostrodontians Prozostrodon brasiliensis from the older Hyperodapedon AZ and Brasilodon quadrangularis and Brasilitherium riograndensis from the same Riograndia AZ. The inclusion of Botucaraitherium within a broad phylogenetic analysis, positioned it as a more derived taxon than tritylodontids, being the sister-taxon of Brasilodon, Brasilitherium plus Mammaliaformes. Although the new taxon is based on few cranial elements, it represents a additional faunal component of the Triassic Riograndia AZ of southern Brazil, in which small-sized derived non-mammaliaform cynodonts, closely related to the origin of mammaliaforms, were ecologically well succeed and taxonomically diverse.
