Lead concentration on surface soil (0-20 cm), root and aerial part of natural and cultivated pastures were evaluated, in the rainy season (March 2018), collected in 20 sites of a rural community located 20 km from the La Oroya metallurgical complex , which has been emitting to the environment particulate material with heavy metals since 1922. Lead concentration was determined by flame atomic absorption spectrometry. The data was statistically processed in SPSS 23. Lead levels in the soil, root and aerial part of the cultivated pastures were 224.75 ± 39.41, 169.13 + 58.79 and 20.73 ± 2.52 mg / kg (p <0.01). In natural pastures values were 210.87a ± 40.37, 184.36b + 52.66 and 19.47c ± 3.12 mg / kg (p <0.01). There are no differences between cultivated and natural pastures. Lead transfer factor from soil to root of cultivated and natural pastures was 0.75 and 0.87. Lead transfer factor value from soil to aerial part of cultivated and natural pastures was 0.092 in both. High lead content in soil and aerial part of the pastures used as food for high Andean cattle is a public health problem; livestock products produced in these soils would not be fit for human consumption.

“…Composition analyses of the soundscapes can contribute to the understating of how species are distributed in the landscape (Campos‐Cerqueira and Aide ) and how human impacts, such as mining and oil exploration, affect and structure the acoustic communities (Alvarez‐Berríos et al. ; Duarte et al. , Deichmann et al.…”

Despite several efforts to quantify the effectiveness of forest certification in developing sustainable use of forest resources, there is little evidence that certified forests are more effective in conserving fauna than non‐certified managed forest. To evaluate the impact of forest certification on the fauna, we compared the biodiversity in reference sites (n = 23), Forest Stewardship Council (FSC) certified management sites (n = 24) and non‐FSC management sites (n = 20) in the Tahuamanu region of Peru, during the dry season of 2017. Specifically, we determined if the acoustic space used (ASU), soundscapes composition, and the bird richness and composition significantly varied among the three management types. Variation in ASU was best explained by management type and mean ASU in the FSC sites was significantly greater than the reference and non‐FSC sites, possibly suggesting greater richness of acoustically active species. An ordination analysis of the soundscapes showed that there was a significant difference among the three management types. There was greater dissimilarity in soundscape composition between the FSC and non‐FSC sites, and greater overlap between FSC and reference sites. Bird identifications resulted in 11,300 detections of 226 bird species. Bird species richness and composition were not significantly different among the management types, indicating, in this context, that birds may not be the best indicators of different management strategies. The weak discrimination by the bird community is likely due to their dispersal ability, undisturbed primary forest matrix, and the occurrence of bamboo patches. The differences in ASU among the management types were most likely due to differences in acoustically active insects, which may be more sensitive to changes in microhabitat differences. Our findings correspond with the conclusions of other studies that certified forests can maintain levels of fauna biodiversity similar to those of undisturbed primary forest in the Amazon region.

It's time to listen: there is much to be learned from the sounds of tropical ecosystems

et al. 2018

Knowledge that can be gained from acoustic data collection in tropical ecosystems is low‐hanging fruit. There is every reason to record and with every day, there are fewer excuses not to do it. In recent years, the cost of acoustic recorders has decreased substantially (some can be purchased for under US$50, e.g., Hill et al. 2018) and the technology needed to store and analyze acoustic data is continuously improving (e.g., Corrada Bravo et al. 2017, Xie et al. 2017). Soundscape recordings provide a permanent record of a site at a given time and contain a wealth of invaluable and irreplaceable information. Although challenges remain, failure to collect acoustic data now in tropical ecosystems would represent a failure to future generations of tropical researchers and the citizens that benefit from ecological research. In this commentary, we (1) argue for the need to increase acoustic monitoring in tropical systems; (2) describe the types of research questions and conservation issues that can be addressed with passive acoustic monitoring (PAM) using both short‐ and long‐term data in terrestrial and freshwater habitats; and (3) present an initial plan for establishing a global repository of tropical recordings.
