“…The transition metals Zn and Ni, found in high concentrations in samples PS and PL (Table 2), confirm the geochemical signatures of guano in the phosphate minerals (Tatur, 1989;Tatur & Keck, 1990;Zdanowski et al, 2005;Liu et al, 2008;Oliveira et al, 2009;Wurster et al, 2015). High content Rb were also detected, which may be another guano geochemical signature, given that the LC/SJ samples are poor in this element.…”

“…The P 2 O 5 increase is related to the presence of guano in the caves, given that organic-rich bat guano, in addition to being composed of carbon, nitrogen and sulfur, also contain high content of phosphorus released due to organic reactions in acidic conditions (Hutchinson, 1950;McKelvey, 1967;Forti, 2001;Onac et al, 2002;Zdanowski et al, 2005;Albarède, 2009;Onac & Forti, 2011;Tămaş et al, 2011).…”

Abstract:The Carajás Mineral Province has one of the largest concentrations of caves in Brazil, and its iron ore is among the country's main exports. As a result of iron ore intense extraction, new environmental policies have been implemented. In an attempt to balance economic activity and environmental conservation, an inventory and a relevance-based classification of caves were implemented in 2008 as criteria for environmental licensing of mining ventures. This implementation motivated the present study of phosphate speleothems in Carajás' caves developed in ferriferous rocks. The objectives of this study are to describe the phosphate minerals and their formation processes based on geochemical and petrographic analysis, X-ray powder diffraction (XRD), differential scanning calorimetry coupled with thermogravimetry (DSC-TG), Fourier-transform infrared (FTIR) and scanning electron microscopy (SEM). Eight caves were selected for this study, along the slopes of the plateaus from Carajás. The phosphate speleothems usually present compositional zoning, with strengite-phosphosiderite in the core and leucophosphite-spheniscidite on the edges. This zoning cannot be related to leucophosphite-spheniscidite decomposition, since the DSC-TG curves show that dehydroxylation and loss of NH 3 from leucophosphite-spheniscidite require temperatures higher than 250°C. FTIR results allowed us to identify the NH 4 functional group, based on absorbance bands at 1,430 and 3,040 cm -1 , which associated to other data confirm the presence of spheniscidite. Refined values of the unit cell parameters for spheniscidite (a = 9.803 Å, b = 9.722 Å, c = 9.858 Å, β = 102.78°) obtained using the Rietveld refinement, were slightly lower than those of the ICSD-39654 file. These smaller values are attributed to increasing substitutions of K + for NH 4 + , and Al 3+ for Fe 3+ . Based on the geochemical analysis, significant enrichment in P 2 O 5 , Zn, Ni, and Rb was detected in phosphate speleothems, and phosphatized laterite, suggesting that bat guano was a potential source of these elements.cave, iron ore, phosphate speleothems, spheniscidite, Carajás

“…Uric acid is a major component of guano-enriched, ornithogenic soil (Speir and Cowling 1984), which can remain in arid soils (like the soils studied here) for extended periods (Ramsay and Stannard 1986). Relatively high numbers of culturable uric acid degrading bacteria are known to occur in ornithogenic soils (Pietr 1986), including members of genus Psychrobacter, which has been isolated from ornithogenic soil (Bowman et al 1996) as well as penguin guano (Zdanowski et al 2005).…”

Abstract. Bird guano has been shown to alter the structure and function of ecological communities.Here we characterize the effects of vulture guano on the phylogenetic structure, taxa richness, and abundance in soil bacterial communities within an African savanna. By altering soil chemistry and nutrient status, vulture guano appears to play a role in influencing the structure of soil bacterial communities. DNA was extracted from soil collected under twenty trees: five African white-backed vulture (Gyps africanus, WBV) nesting sites, five lappet-faced vulture (Torgos tracheliotos, LFV) nesting sites and ten control sites where no sign of vulture activity was detected. Using a high-density phylogenetic microarray (PhyloChip G2), we identified 1,803 bacterial Operational Taxonomic Units (OTUs) in the twenty samples. Analysis of beta-diversity using the Unifrac distance metric demonstrated that WBV nesting sites were phylogenetically distinct from both control trees and LFV nesting sites. We detected a higher degree of phylogenetic clustering in soil bacterial communities associated with both WBV and LFV nesting sites compared to control sites, suggesting that the deposition of guano increases the strength of habitat filtering in these communities. Canonical correspondence analysis revealed that variation in OTU intensity (a measure of relative abundance) could be related to variations in pH, electrical conductivity and total nitrogen content. WBV sites explained 10% to 22% of the variation in OTU intensity. The elevated total nitrogen and lower pH characteristic of soils associated with vultures may favor Proteobacteria and suppress Firmicutes, particularly Clostridia and Bacilli. Acidic aggregations of vulture guano may be unlikely to support longterm survival of spore-forming Firmicute pathogens and thus may limit the role that vultures play as potential disease vectors.

“…Variability in soil d 13 C has a multitude of causes, but within a particular site older, mineral-associated soil C has a c. 3 higher d 13 C than younger soil C fractions (Garten et al 2007). Within guano, lipid makes up 40Á50% m/m of fresh penguin guano (Zdanowski et al 2005); lipid in living seabirds has a d 13 C that is 4Á6 lower than bulk tissue (Thompson et al 2000 We conclude that blue penguin burrow invertebrates participate in food webs derived from both terrestrial and marine burrow materials, with guano playing a central role consistent with its abundance. Co-processing of feathers and guano, or soil and guano, is indicated for some taxa.…”
