“…Similar results have been reported by others (Savario & Hoy, 2010), for soils under sugarcane production in the State of São Paulo (Brazil). Much of the environmental variability that we observed likely arose from local variation in agricultural practices.…”

“…Based on these analyses, the sum of bases (SB), cation exchange capacity (CEC) and base saturation (V%) (van Raij et al, 2001) were also calculated. These variables were selected because they are commonly associated with different agricultural practices, and because they have been frequently reported to influence the composition of fungal communities in soil (Pankhurst et al, 2003;Graham & Haynes, 2006;Srikumar et al, 2009;Savario & Hoy, 2010;Pupin & Nahas, 2011).…”

Aim Despite the important roles that microbial communities play world‐wide, relatively little attention has been given to the processes that shape their distributions. Of those studies that have addressed this question, the vast majority has focused on temperate regions and relatively undisturbed environments. In particular, tropical agricultural environments have been rarely studied, and it is commonly assumed that agriculture reduces spatial variation in microbial communities, especially in soil. Here, we evaluated the diversity and abundance of fungal communities in soils used for the cultivation of the world's largest crop, sugarcane, in the world's largest producer, Brazil. Location State of São Paulo, Brazil. Methods Our study sampled across 23,022 km2 of the State of São Paulo, Brazil, in an area that is a major producer of sugarcane. The composition of the fungal communities was estimated via terminal restriction fragment length polymorphism (T‐RFLP) analysis, and the fungal abundance was estimated by quantitative PCR (qPCR). Results We observed that the variance in community composition explained by soil characteristics was 2.88%, and that explained by climate variables was 2.93%. In contrast, geographical distance explained 50.75% of the variance. Moreover, the distribution of fungal species abundance fits a neutral model that assumes only dispersal and drift better, rather than models that assume environmental filtering. Main conclusions Our work demonstrates that fungal communities in soil can exhibit biogeographical patterns, even in agricultural soils, and that these patterns are likely to be due at least in part to dispersal limitation.

“…Furthermore, fire and pesticide can eliminate other organisms in the sugarcane plantations, reducing the amount of forage for birds and rodents. For example, studies in other countries have shown the negative impacts of agro-industrial management associated with sugarcane production on microbial communities [50], bacterial communities [51], arthropods [52], and spider populations [53].

Despite the intense debates on the land acquisition effects of large-scale Ethiopian sugarcane plantations and the consequences for food security, the impact on biodiversity has received less attention. We compared remnant patches in the sugarcane zone to the adjacent woodlands to determine the impacts of sugarcane on the diversity, composition, and structure of woody species. We recorded individual woody specimens with diameter at breast height (DBH) ≥ 2.5 cm from 56 quadrats of 200 m 2 at each site in a systematic, random, and gradient-oriented transect design. In addition, we employed a trait-based risk assessment framework to examine the threat posed by agro-industrial sugarcane production on mammals, birds, and rodents. A total of 56 woody species, 38 in the woodlands and 30 in the sugarcane zone, were identified. The proportion of non-native woody species was higher (63%) in the sugarcane zone than in the adjacent woodlands (1%). The rodents and mammals were more abundant in the woodlands than in the sugarcane zone. Although we did not investigate all of the bird and mammal species, our results identified six rodent species, five mammal species, and one bird species as susceptible to sugarcane agriculture activities. The results suggest that large-scale agro-industrial sugarcane production impacts species diversity, composition and abundance of species, and species' resource requirements.

“…El contenido de materia orgánica según Faye-Savario (2011);Cabrera et al (2010);Naranjo et al (2006) y Ribón Carrillo et al (2003 presenta una tendencia a disminuir con el paso de los años de monocultivo de la caña de azúcar; es decir, después de desmontar una selva, el contenido de MO (entre 6% y 10%) desciende en los primeros años de 25 a 50%, como el caso de estudio, esta reducción se hace más lenta y progresiva durante el tiempo del cultivo, hasta alcanzar un valor estable después de 15 años (3% y 4 %). García-Silva et al (2006) concluyeron que el uso antrópico del suelo en especial por monocultivos como la caña de azúcar, es el principal responsable de la reducción de sus reservas orgánicas; se han estimado pérdidas entre 30% y 50% del carbono orgánico edá-fi co (COS) en la capa arable, después de 20 a 30 años de cultivo Sin embargo, las fuentes de MO pueden disminuir a una alta velocidad por las prác-ticas de eliminar los residuos de la cosecha (paja, tlazole, puntas de caña y cogollos) mediante quema y requema (90% de la zona de estudio la emplea como práctica convencional), ya que los residuos pueden ser oxidados más rápidamente debido al aumento de la temperatura por efecto de la quema de la caña de azúcar antes de su cosecha, posteriormente, el contenido de MO del suelo tiende a estabilizarse hasta los 20 años de cultivo, pero sin alcanzar su nivel inicial, registrándose a los 30 años de cultivo una reducción en su contenido por la quema más que a las labores culturales del mismo y el monocultivo (Ribón Carrillo et al, 2003).…”
