AbstractLand use is known to affect water quality yet the impact it has on aquatic microbial communities in tropical systems is poorly understood. We used 16S metabarcoding to assess the impact of land use on bacterial communities in the water column of four streams in central Panama. Each stream was influenced by a common Neotropical land use: mature forest, secondary forest, silvopasture and traditional cattle pasture. Bacterial community diversity and composition were significantly influenced by nearby land uses. Streams bordered by forests had higher phylogenetic diversity (Faith’s PD) and similar community structure (based on weighted UniFrac distance), whereas the stream surrounded by traditional cattle pasture had lower diversity and unique bacterial communities. The silvopasture stream showed strong seasonal shifts, with communities similar to forested catchments during the wet seasons and cattle pasture during dry seasons. We demonstrate that natural forest regrowth and targeted management, such as maintaining and restoring riparian corridors, benefit stream-water microbiomes in tropical landscapes and can provide a rapid and efficient approach to balancing agricultural activities and water quality protection.

We studied the vegetation of a 260 ha Hungarian Grey Cattle pasture near Páskom, which can be found in Zámoly basin. We carried out our surveyes in May 2012. The pasture can be divided into five parts. One part, approximately the half of the area (150.83 ha), is an old-field grassland, which was overseeded 20 years ago. The other half of the pasture was restored (109.17 ha) in 4 different ways in 2009 and then was mowed until 2011. Seven relevés were made in each part of the pasture (the occurence of species and their cover value were recorded). The aim of our study was to compare the effects of the different restoration methods and mowing on the botanical composition of the pasture. The results showed, that the grassland restored with hay transfer method was the most similar to the natural conditions. The greatest number of species was recorded in that part and the species of natural grasslands become dominant. The directly sowed and the spontaneous grassland parts separated chiefly from the semi-natural 20 years old grassland.

Resumo. O objetivo deste estudo foi avaliar a contribuição de dois ambientes antrópicos (monocultura de Eucalyptus e pastagem de bovinos) como habitats para espécies de formigas edáficas de Floresta Estacional Decidual (mata nativa). Foram realizadas coletas semanais entre outubro de 2009 e março de 2010 utilizando armadilhas de solo do tipo Pitfall, no município de Santa Cruz do Sul, RS, Brasil. Duas hipóteses foram testadas: (1) a diversidade de formigas é maior na mata nativa em relação a pastagem de bovinos e a monocultura de Eucalyptus; (2) ambientes florestais (mata nativa e monocultura de Eucalyptus) apresentam assembleias de formigas mais similares entre si do que com ambientes abertos (pastagem de bovinos). Foi observado 930 espécimes de formigas, distribuídas em seis subfamílias, 17 gêneros e 28 espécies. As curvas geradas pelos estimadores de espécies indicam que a amostragem foi suficiente. A mata nativa foi mais rica que as outras fitofisionomias, corroborando com a hipótese (1). Embora a pastagem de bovinos tenha sido estatisticamente mais semelhante com a monocultura de Eucalyptus, possivelmente por serem ambientes mais impactados que a mata nativa, houve um alto compartilhamento de espécies entre os ambientes florestais. Esses resultados demonstram a importância da preservação de ambientes naturais como repositórios da mirmecofauna.Contribution of anthropogenic environments as habitats for soil ant from Deciduous Seasonal Forest in Southern BrazilAbstract. The aim of this study was to evaluate the contribution of two anthropic environments (Eucalyptus monoculture and cattle pasture) as habitats for edaphic ant species of Deciduous Seasonal Forest (native forest). Weekly collections were conducted between October 2009 and March 2010 using Pitfall traps, in the municipality of Santa Cruz do Sul, RS, Brazil. Two hypotheses were tested: (1) the diversity of ants is greater in the native forest in relation to cattle pasture and a monoculture of eucalyptus; (2) forest environments (native forest and Eucalyptus monoculture) present ant mounts more similar to each other and with open environments (pasture area). It was observed 930 occurrences of ants, distributed in six subfamilies, 17 genera and 28 species. Curves generated by species estimators indicate that sampling was sufficient. The native forest was richer than the other phytophysiognomies, corroborating with the hypothesis (1). Although the pasture area has been established statistically with the Eucalyptus monoculture, possibly for being environments more impacted than the native forest, there was a high species sharing among the forest environments. These results demonstrate the importance of the preservation of natural environments as repositories of ant fauna.

An examination of oribateid mites from cattle pastures in south-east Queensland showed Zygoribatula longiporosa Hammer to be the only species infested with cysticercoids. By feeding a number of these mites from a cattle pasture to a worm-free calf, the cysticercoids proved to be those of Moniezia benedeni (Moniez 1879). Cysticercoids of a similar type were also found in Z. longiporosa collected from a sheep pasture.

AbstractSlender speedwell (Veronica filiformis Smith, family Plantaginaceae) is a non-native and invasive species of grassland in the Europe. The aim of the study was to test the ability of the growth and spreading in nine differently managed grasslands (mowing, mulching, grazing). The best survival was found in two-years mowed lots with fertilisation and in all lots with not permanent cattle pasture crops. There were found the highest number of survived plants and plants with big “rosette“ diameters. Number of survived plant for two seasons was 18 and total number of vegetative peaks per plant was 688. The potential for the spreading of such plant population is great. On the other hand, plants did not survived in lots with mulch treatment and in fenced lots with permanent cattle grazing.
