Resumo: Avaliaram-se os efeitos da idade do animal e da proporção de volumoso nas dietas sobre a biodigestão anaeróbia dos dejetos de cabritos Saanen. Foram utilizadas as fezes produzidas por cabritos Saanen aos 90, 120 e 150 dias de idade e alimentados com dietas de três relações volumoso:concentrado (80:20, 60:40 e 40:60), representando as dietas 1, 2 e 3, respectivamente. Utilizaram-se biodigestores tipo batelada de bancada com capacidade para 12 litros de substrato em fermentação e 8% de sólidos totais iniciais para determinação das produções e dos potenciais de produção de biogás e metano, da redução de sólidos voláteis e quantificação dos teores de minerais no afluente e efluente. As maiores reduções de sólidos voláteis foram observadas nos substratos preparados com as fezes de cabritos aos 150 dias alimentados com a dieta com relação volumoso:concentrado de 40:60. Os melhores rendimentos de substrato ou fezes foram obtidos com os dejetos dos cabritos de 120 e 150 dias de idade alimentados com a dieta com relação volumoso:concentrado 40:60. As maiores concentrações de minerais nos biodigestores foram observadas para as fezes de cabritos de 150 dias de idade alimentados com a dieta com relação volumoso:concentrado 40:60. A biodigestão anaeróbia é eficiente na remoção de coliformes nos dejetos de caprinos, proporcionando efluentes com no máximo 4,3 × 102 coliformes totais termotolerantes por grama de material.
[Anaerobic biodigestion of manure of Saanen goats fed diets with different proportions of roughage and concentrate].
Abstract: It was evaluated the effects of age of the animal and of the proportion of dietary roughag on anaerobic biodigestion of the manure of Saanen kids. It was used the feces produced by Saanen kids at 90, 120 and 150 days of age and fed diets with three roughage:concentrate ratios (80:20, 60:40 and 40:60), representing diets 1, 2 and 3, respectively. It was used batch digesters of bench with capacity for 12 liters of substratum in fermentation process and 8% of initial total solids for determination of biogas and methane productions and production potentials, and reduction of volatile solids and quantification of mineral contents in affluent and effluent. The greatest volatile solid reductions were observed in substrata prepared with feces of goats at 150 days of age fed diets with roughage:concentrate ratio of 40:60. The best results of substratum or feces were obtained with manure of goats at 120 and 150 days of age fed diet with 40:60 roughage:concentrate ratio. The greatest concentrations of minerals in the biodigesters were observed for feces of goats at 150 days of age fed the diet 40:60 roughage:concentrate ratio. Anaerobic biodigestion is efficient in removing coliforms from goat manure, providing effluents with maximum of 4.3 × 102 of total and thermotolerant coliforms per gram of material.

Climate change can have a plethora of effects on organisms above and below the ground in terrestrial ecosystems. Given the tremendous biodiversity in the soil and the many ecosystem functions governed by soil organisms, the drivers of soil biodiversity have received increasing attention. Various climatic factors like temperature, precipitation, soil moisture, as well as extreme climate events like drought and flood have been shown to alter the composition and functioning of communities in the soil. Earthworms are important ecosystem engineers in the soils of temperate and tropical climates and play crucial roles for many ecosystem services, including decomposition, nutrient cycling, and crop yield. Here, we review the published literature on climate change effects on earthworm communities and activity. In general, we find highly species- and ecological group-specific responses to climate change, which are likely to result in altered earthworm community composition in future ecosystems. Earthworm activity, abundance, and biomass tend to increase with increasing temperature at sufficiently high soil water content, while climate extremes like drought and flooding have deleterious effects. Changing climate conditions may facilitate the invasion of earthworms at higher latitudes and altitudes, while dryer and warmer conditions may limit earthworm performance in other regions of the world. The present summary of available information provides a first baseline for predictions of future earthworm distribution. It also reveals the shortage of studies on interacting effects of multiple global change effects on earthworms, such as potential context-dependent effects of climate change at different soil pollution levels and across ecosystem types.
