“…These natives were expected to affect soil differently as they belong to distinct functional groups-forbs and graminoids, which differ from each other in many traits, for example, tissue density, leaf thickness, leaf life span, and litter decomposability (Scharfy et al 2011). It should be kept in mind that A. vulgaris and P. arundinacea are native expansive species in Europe, but noxious invaders in some other parts of the world, for example, North America (Weston et al 2005;Jacinthe et al 2010). In this context, data on their effects on soil gathered in this study seem particularly valuable.…”

Differential influence of four invasive plant species on soil physicochemical properties in a pot experiment

et al. 2017

Purpose This study compared the effects of four invasive plants, namely Impatiens glandulifera, Reynoutria japonica, Rudbeckia laciniata, and Solidago gigantea, as well as two native species-Artemisia vulgaris, Phalaris arundinacea, and their mixture on soil physicochemical properties in a pot experiment. Materials and methods Plants were planted in pots in two loamy sand soils. The soils were collected from fallows located outside (fallow soil) and within river valley (valley soil) under native plant communities. Aboveground plant biomass, cover, and soil physicochemical properties such as nutrient concentrations, pH, and water holding capacity (WHC) were measured after two growing seasons. Discriminant analysis (DA) was used to identify soil variables responsible for the discrimination between plant treatments. Identified variables were further compared between treatments using one-way ANOVA followed by Tukey's HSD test. Results and discussion Plant biomass, cover, and soil parameters depended on species and soil type. DA effectively separated soils under different plant species.

“…Both plants are tall and reach 0.5-2.5 m in height. Artemisia vulgaris and P. arundinacea are considered invaders in North America, infesting roadsides, waste areas, agronomic settings, and/or wetlands (Weston et al 2005;Jacinthe et al 2010). …”

“…Os valores de diversidade metabólica, medidos por meio do índice de Shannon, variaram de 6,93±0,29 a 7,42±0,07 nas áreas sem pastejo e P-30, respectivamente, e são superiores àqueles reportados (2,0 a 4,5) para sistemas de manejo com plantas de cobertura, em sucessão a culturas comerciais (grãos), em solos de regiões temperadas (Papatheodorou et al, 2008;Jacinthe et al, 2010). Provavelmente, a maior interação solo-planta, na mistura da pastagem de aveia-preta + azevém, associada às condições climáticas em que foi realizado o presente trabalho, favoreceu a diversidade da microbiota do solo.…”

Resumo -O objetivo deste trabalho foi avaliar a diversidade metabólica e a atividade microbiana, em sistema de integração lavoura-pecuária em plantio direto, sob diferentes intensidades de pastejo e produção de soja. O experimento foi realizado em São Miguel das Missões, RS, em Latossolo Vermelho distroférrico argiloso, submetido ao pastejo a 10, 20, 30 e 40 cm de altura de azevém + aveia-preta, e sem pastejo, no inverno. A diversidade metabólica foi avaliada com microplacas Biolog EcoPlate pelo índice de diversidade de Shannon, e a atividade microbiana pelo método de hidrólise do diacetato de fluoresceína. Houve maior diversidade funcional a intensidades moderadas de pastejo (20 a 40 cm). A maior atividade microbiológica no solo ocorreu no tratamento sem pastejo, em consequência da grande quantidade de resíduos vegetais remanescentes. A diversidade funcional da microbiota e a atividade microbiana tiveram alterações causadas pelas intensidades de pastejo, que podem ser utilizadas como indicadores de qualidade do solo, em sistema de integração lavoura-pecuária em plantio direto.Termos de indexação: diacetato de fluoresceína, plantio direto, qualidade do solo. Metabolic diversity and microbial activity in the soil in an integrated crop-livestock system under grazing intensitiesAbstract -The objective of this work was to evaluate the metabolic diversity and the microbial activity in an integrated crop-livestock system under no-tillage, and at different grazing intensities and soybean production. The experiment was carried out in São Miguel das Missões county, in Rio Grande do Sul state, Brazil, in a clayey Rhodic Hapludox (Oxisol), subjected to grazing intensities at 10, 20, 30 and 40 cm-height of pasture with black oat + italian ryegrass, and a nongrazing treatment, in the winter. The metabolic diversity was evaluated with the Biolog EcoPlate technique, by the Shannon diversity index, and the microbial activity by the fluorescein diacetate hydrolysis method. There was higher functional diversity at the moderate grazing intensities (20 to 40 cm). The highest microbial activity, in the soil, occurred in the nongrazing treatment because of the high quantity of plant residues. Microbial functional diversity and activity had alterations caused by the grazing intensities, which can be used as soil quality indicators on integrated crop-livestock systems under no-tillage.

“…These results could potentially be explained by a negative influence of secondary compounds in the closed canopy tree leaves (Earl et al 2011, Burrow and Maerz 2021). Tannins directly impair survival in other species of tadpoles (Earl and Semlitsch 2015), and among plant species with values available in the literature, those used in the closed canopy vegetation treatment have higher phenolics and tannins than those used in the open canopy treatment (Pritchard et al 1997, Osborne et al 2007, Jacinthe et al 2010, McElrone et al 2010). It may also be the case that the vegetation effect on tadpoles was partly or primarily mediated through effects on periphyton and phytoplankton in the mesocosms (Burrow and Maerz 2022).…”

Assessing factors that increase dusky gopher frog larval performance in open‐canopy wetlands

Amphibians are declining worldwide, and research on their habitats and ecology is important for their conservation. The endangered dusky gopher frog (Rana sevosa) breeds exclusively in isolated, open canopy wetlands, usually with extensive herbaceous growth. Larvae of the dusky gopher frog have higher growth and survival under open canopy than under closed canopy conditions. The mechanisms whereby this occurs are poorly understood, however. In the summer of 2021 in Harrison County, Mississippi, USA, we conducted a complete factorial experiment in mesocosms to compare the relative influence of factors differing between open and closed canopy ponds on larvae. A heat and light treatment consisted of one third of tanks being exposed to full sunlight, one third of tanks being shaded with 70% shadecloth, and the final third being shaded with 70% shadecloth but heated to mimic the temperature of the full sun tanks. In addition, tanks received a closed canopy tree leaf litter mixture or an open canopy herbaceous vegetation mixture, and vertical vegetation‐like structure made of polypropylene rope or not. Cool shaded tanks and heated shaded tanks had identical survival to metamorphosis at 74.7% and produced frogs with an average mass of 2.21 g and 2.09 g, respectively, while tanks in full sunlight achieved significantly higher 93.4% survival to metamorphosis and an average mass of 2.64 g. The open canopy vegetation mixture yielded an average tank survival of 88.3% and mass of 2.94 g, compared to closed canopy vegetation tanks with a significantly lower survival of 73.5% and average mass of 1.61 g. Added structure had no effect on survival or mass. These results indicate that sunlight (not heat alone) and herbaceous plants are important in increasing dusky gopher frog survival and mass in open canopy conditions and suggest that management for these characteristics receive priority in captive‐rearing programs and habitat restoration.
