The ichthyofauna from 3 streams (Água Boa, Perobão, and Santa Maria) to the lower Iguatemi River were inventoried, which is located in the upper Paraná river basin, in Mato Grosso do Sul state, Brazil. Sites in the upper, intermediate, and lower portions of each stream were quarterly electrofished from March to December 2008. All sampled fish (n = 6,816 individuals) represented 43 species of 5 orders, and 16 families. The most abundant species was Phalloceros harpagos (63.5%), followed by Astyanax aff. paranae (10.6%), Hypostomus ancistroides (5.9%), Gymnotus inaequilabiatus (3.4%), and Knodus moenkhausii (2.7%). Despite the high ichthyofauna richness in the lower portion of Iguatemi River, the need to implement and/or expand soil conservation practices and riparian forest restoration is of utmost importance to maintain these populations in the long term.

O ambiente SIG (Sistema de Informações Geográficas) é o ideal para integrar dados, informações e cartas de naturezas diferentes. Por exemplo, dados climáticos e cartas topográficas ou de solos podem ser analisados em conjunto, levando toda a informação para uma base comum, o que permite a sua integração e uso. A Equação Universal de Perdas dos Solos (EUPS ou USLE) é atualmente utilizada, com sucesso, como uma forma para a avaliação da perda dos solos por erosão laminar e foi aplicada para a Bacia do Rio Taquarizinho (ao Sul de Coxim, Mato Grosso do Sul), região que apresentou grandes modificações no tipo de uso e ocupação do solo no período analisado. Neste trabalho são apresentados os parâmetros envolvidos com a USLE, alguns obtidos da digitalização de cartas temáticas e tabelas como de Erosividade das chuvas (R), Erodibilidade do solo (K) ou Uso e Manejo do Solo e Práticas Conservacionistas (CP) e outros, como Comprimento (L) e Declividade de vertentes (S,) obtidos em ambiente SIG, através de dados topográficos. O ambiente SIG permitiu a completa integração entre os dados para a obtenção dos parâmetros da USLE e os resultados. Para a Bacia do Rio Taquarizinho a USLE foi aplicada em três diferentes momentos: 1966, 1985 e 1996. Esta aplicação multitemporal mostrou a tendência evolutiva do processo erosivo na região. Para os valores absolutos da taxa de erosão laminar dos solos, de 1966 a 1996, em alguns locais, o desmatamento implicou num aumento da taxa de erosão laminar dos solos em mais de 50 vezes. As perdas médias anuais de solo por erosão laminar foram representadas por valores médios, para toda a Bacia do Taquarizinho, de 4,44 ton/ha. para 1966, de 5,53 ton/ha. para 1985 e de 8,65 ton/ha. para 1996. MULTITEMPORAL EVALUATION OF SOIL LOSS IN THE TAQUARIZINHO BASIN, MATO GROSSO DO SUL - BRAZIL Abstract The GIS - Geographic Information System environment is ideal for integrating data, information and different kinds of maps. For example, climate data and topographic or soil cover maps can be analyzed together, bringing all the information into a common base, thus permitting integration and use. The Universal Soil Loss Equation (USLE) is currently used successfully as a form of evaluating soil loss via laminar erosion, and it was applied to the Taquarizinho River Basin (to the south of Coxim, Mato Grosso do Sul State), a region which showed great changes in the type of use and occupation of the soil during the period analyzed. In the present work are presented the parameters involved in the USLE, some obtained from the digitalization of thematic maps and tables, such as the Rain Erosive Potential (R), Soil Erodability (K), and Cover and Management of the Soil and Conservation Practices (CP), and others, such as Length (L) and Slope Declivity (S), obtained from the GIS environment, from topographic data. The GIS environment permitted a complete integration between the data used to obtain the USLE parameters, and the results. For the Taquarizinho River Basin, the USLE was applied to three different periods: 1966, 1985 and 1996. This multi-temporal application showed a tendency of evolving erosion in the region. Calculations of the absolute values of rates of laminar erosion of the soils indicate that deforestation has lead to an increase of more than fifty times in such erosion, from 1966 to 1996. The mean annual losses of soil from laminar erosion for the entire Taquarizinho River Basin are calculated to have been 4.44 ton/ha in 1996, 5.53 ton/ha in 1985, and 8.65 ton/ha in 1996.

The Porto Murtinho Pantanal lies at the limit of the Upper Paraguay River basin, and despite its biogeographical importance, several aspects of the ecology of the fish assemblage are not known. Monthly samples of fish associated with aquatic macrophytes were taken from February 2009 through January 2011. A total of 46,327 individuals were collected, belonging to 144 species. Characiformes and Siluriformes were the predominant orders, and Odontostilbe pequira, O. paraguayensis and Bryconamericus exodon were the most abundant species. Two species, Cynopotamus sp. and Pimelodus mysteriosus, were recorded for the first time in the Pantanal, and a new occurrence record of Cichla piquiti was observed, representing an approximately 400 km range expansion in your distribution area in the Pantanal.

Coleoptera of the family Geotrupidae play an important ecological role in the decomposition of animal and plant organic matter. In Brazil there is little information on the diversity and distribution of this group, thus, this work had a purpose to study Geotrupidae species, occurring in Aquidauana, MS. A survey for geotrupids was conducted in Aquidauana, Mato Grosso do Sul, Brazil. Beetles were captured using a light trap over a period of two years, from January 2006 to December 2007. A total of 907 specimens were collected and identified to eight species. From the subfamily Bolboceratinae, the species identified were Bolbapium minutum (Luederwaldt, 1929) and Pereirabolbus castaneus (Klug, 1845). In the subfamily Athyreinae the species identified were Athyreus bilobus Howden & Martínez, 1978, Parathyreus aff. bahiae, Neoathyreus aff. julietae, N. sexdentatus Laporte, 1840, N. centromaculatus (Felsche, 1909) and N. goyasensis (Boucomont, 1902). Four species (A. bilobus, N. centromaculatus, N. goyasensis and P. castaneus) are reported for the first time in Aquidauana, MS, Brazil. The most abundant species, representing 85.9% of the total capture, was B. minutum. The greatest numbers of specimens was caught from October to December of both years of the study.

We present herein a synthesis of faunistic data from caves in the Serra da Bodoquena karst area, middle Paraguay River basin, Mato Grosso do Sul State. Those include phreatic, submerged and dry caves. Emphasis is given to troglobites (exclusively subterranean species), potentially threatened due to their morphological, physiological and behavioral specializations, associated to generally small distributions. The Bodoquena karst area distinguishes as a spot of high diversity of troglobites, such as trichomycterid and heptapterid catfishes, aquatic planarians and gastropods, arachnids (Eusarcus opilionids, ctenid spiders), Polydesmida diplopods, several collembolans, some insects, and Peracarida crustaceans, which include interesting phylogenetic relicts as spelaeogriphaceans. Four geographic compartments corresponding to microbasins, seemingly with biogeographic importance for the subterranean fauna, are recognized. Phreatobic troglobites (Trichomycterus catfishes, aquatic peracarids, planarians) distribute widely across these compartments and some well beyond (the spelaeogriphacean Potiicoara brasiliensis reaches Mato Grosso state), while those living in base-level streams (Rhamdia and Ancistrus catfishes) and the terrestrial ones, that live in the vadose (aerated zone) are generally restricted to one compartment. Many subterranean ecosystems in Mato Grosso do Sul are endangered by several threats described here and urgent actions for effective protection are required to guarantee a sustainable use of the land and the karst aquifers.

Abstract: The objective of this work was to evaluate the grain yield of soybean and corn cultivars cropped in succession, in different sowing dates. The experiment was carried out in the municipality of Dourados, in the state of Mato Grosso do Sul, Brazil, during three growing seasons, in the sowing dates: 9/15, 10/1, 10/15, and 11/1 for soybean; and 2/1, 2/15, 3/1, and 3/15 for corn. Although soybean yields are strongly affected by the crop season, sowing between late September and early October results in higher long-term yields. Planting corn in succession in mid-February provides the highest grain yield in the southern region of the state Mato Grosso do Sul; therefore, there is no need for an early soybean sowing in September, in order to ensure corn planting in January. Soybean-corn succession in which soybean is sown in early October and corn in mid-February results in higher total grain yields and reduces the climatic risk associated with these crops in the region.

Astyanax biotae é uma espécie originalmente descrita em um afluente do Rio Paranapanema, bacia do alto Paraná. Durante amostragens realizadas em drenagens dos rios Ivinhema e Verde, no sistema do alto Paraná, em Mato Grosso do Sul, exemplares de A. biotae foram coletados em cabeceiras de pequenos riachos e em lagoas de várzea, tanto em Unidades de Conservação como em áreas de agricultura intensiva. Os dados morfomerísticos de 20 indivíduos analisados foram similares aos da série-tipo. Exemplares testemunhos estão depositados nas coleções ictiológicas da UFMS (ZUFMS), UEMS (CPUEMS) e UNESP (DZSJRP). Com base nos critérios da IUCN, sugerimos sua classificação como Menos Preocupante (LC) no estado de Mato Grosso do Sul, considerando principalmente a inexistência de ameaças efetivas em duas das áreas de ocorrência da espécie, situadas dentro de Unidades de Conservação. No entanto, reforçamos a urgência em medidas para a proteção das regiões de cabeceiras de riachos, a fim de evitar o aumento do desmatamento, assoreamento e poluição agrícola, problemas recorrentes no Cerrado, que comprometem severamente a manutenção desses hábitats e suas espécies. É necessário investir em estudos sobre a biologia da espécie e ampliar as amostragens, buscando diminuir os vazios amostrais ainda existentes nas drenagens estaduais.

This study aimed to assess the diversity, abundance and seasonal dynamics of Ophioniformes wasps collected throughout a year, as recorded in Malaise traps set at the Reserva Ecológica da Universidade Estadual do Mato Grosso do Sul, a Brazilian Savanna area in Aquidauana city, MS. A total of 621 specimens of Ophioniformes belonging to 11 subfamilies, 30 genera and 106 species were sampled. Despite the impressive number of species found, in a pattern of a few relatively abundant species and many rare ones, our data estimate even higher richness, probably between 125 to 165 species in the studied area. The genera Diadegma, Nonnus, Diradops, Meniscomorpha, Syzeuctus, Ophiopterus and Thyreodon are recorded for the first time in Mato Grosso do Sul State. Among the climatic variables evaluated, mean temperature and relative humidity were positively and significantly correlated with richness and abundance. Our data highlights the huge unknown species richness of these parasitoids in Brazil and the need of taxonomic studies efforts in the future.

High Diversity

Phytoseiidae is the most extensively studied family of predatory mites, some of which are effectively used as biological control agents. Nevertheless, studies of these mites in some Brazilian biomes such as the Pantanal are still scarce. The objective this publication was to assess the diversity of this family in Pantanal vegetation from Mato Grosso do Sul State, Brazil, verifying the importance of the native plants as reservoirs for these mites. Samplings were carried out in five phytophysiognomies of the Pantanal: Cambarazal, Capão (forest islet), Carandazal, Riparian Forest and Paratudal. Thirty-five phytoseiid species were recorded on 40 plant species of 28 families. The most common species were Amblyseius chiapensis De Leon and Euseius concordis De Leon, recorded on 21 and 18 plant species, respectively. Inga vera Willd. (Fabaceae) and Paullinia pinnata L. (Sapindaceae) were the host plants harboring the greatest richness of phytoseiids, 15 and 14 species, respectively. Our results suggest a high diversity of phytoseiid mites in the Pantanal biome. However, as only a small proportion of the total biome area was considered, only a fraction of the mite diversity was probably recovered. Thus, new studies on this biome are needed, especially in other well-preserved native vegetation remnants.

Irrigated Soils

In the Mediterranean basin, edaphic salinization, sodification and alkalinization related to anthropic pressures and climatic changes may hinder the ecosystem sustainability. It is pertinent to study the mid and long-term variability of these soil characteristics in face off the macro agricultural system in use (i.e., irrigation or rain-fed). Four irrigated soils from the Caia Irrigation Perimeter (Portugal), Fluvisols, Luvisols, Calcisols and Cambisols were analysed in the mid-term, from 2002 to 2012, for its available Ca2+, Mg2+, K+ and Na+ content. Overall, Ca2+, K+ and Na+ significantly increased during the period of this study by 25%, 8% and 7%, respectively. Soil organic matter (SOM) and pH for the irrigated soils in the area were already assessed in previous studies with the overall SOM remaining constant (p ≥ 0.05) and pH increasing (p < 0.01) by 5%. We provide the predictive maps for Na+ and the CROSS predictive & HotSpot evolution map from 2002 to 2012. Rain-fed soils were analysed in the long-term, from 1965 to 2012, for their SOM, pH and non-acid cations (Ca2+, Mg2+, K+ and Na+) content. While SOM, pH and the exchangeable Ca2+, Mg2+ and K+ significantly increased (p < 0.01) by 23%, 8%, 60%, 21% and 193%, respectively, exchangeable Na+ significantly decreased (p < 0.01) by 50%. These results may be related to the local climate changes as, according to the Thornthwaite classification, it went from sub-humid with great water excess (C1B2s2b4) in the climate normal 1951/1980 to sub-humid with moderate water excess (C1B2sb4) in 1981/2010 to semi-arid with little to none water excess (DB2db4) in 1991/2020. The irrigated areas in this Mediterranean region are slowly departing from sustainable goals of soil conservation and better edaphic management and conservation practices, that address the registered climatic changes in the area, could be adopted.

The knowledge on the Ephemeroptera, Plecoptera and Trichoptera (EPT) assemblages in running waters of Mato Grosso do Sul State is still deficient. As a contribution to improve this situation, this study presents an inventory of immature EPT assemblages in Miranda River basin. The samples were collected between January and September 2006 from 4th to 7th orders river reaches. A total of 3069 larvae were collected, belonging to 49 genera and 17 families. The caddisflies presented the greatest abundance while the mayflies presented the greatest richness. Of the larvae collected, 22 genera of Ephemeroptera and 20 of Trichoptera are new occurrences for the State. The high genera richness observed in this study, with sites subjected to moderate to high human impacts, as well as the high genera richness indicated by non-parametric estimators and by the genera accumulation curve, indicate that the EPT richness of Miranda River basin is high. This result seems to be related to the environmental heterogeneity of the basin catchment (Cerrado and Pantanal biomes; carbonate, sedimentary and basaltic rocks). Additionally, these results should incentive future ecological and environmental integrity studies in the region, which are urgent in a landscape under fast anthropogenic impacts.
