“…The direct and significant relationship between non-troglobitic species composition with the presence of guano reinforces the importance of food resources for the structuring of Guatemalan cave invertebrate communities. The presence of guano tends to be of extreme importance in permanently dry caves (Ferreira et al, 2007;Ferreira, 2019). In this study, even though most of the caves had water bodies, the guano was still a strong structurer for the cave invertebrate communities.…”

“…Several authors have already shown the importance of guano deposits and vegetal debris inside the cave environment (Decu, 1986;Gnaspini, 1989;Ferreira & Martins, 1998;Ferreira & Martins, 1999;Ferreira et al, 2000;Ferreira et al, 2007;Santana et al, 2010;Schneider et al, 2011). Beyond providing habitat availability, they also act as the main food sources for the lower levels of the food web, allowing the occurrence of greater species richness (Pellegrini & Ferreira, 2012;Pellegrini & Ferreira, 2013;Jaffé et al, 2016;Ferreira, 2019). The direct and significant relationship between non-troglobitic species composition with the presence of guano reinforces the importance of food resources for the structuring of Guatemalan cave invertebrate communities.…”

“…The abundance of guano in a cave can eventually attract a huge variety of invertebrates, most of them non-troglobites, which can lead to the emergence and establishment of large invertebrate populations and consequently a high level of biological interactions onto it. The presence of these communities on an ephemeral resource such as guano might repel the troglobitic species, which are often more sensitive, from these habitats (Ferreira et al, 2007), although there are exceptions (Ferreira, 2019).…”

Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live in subterranean habitats. Using 30 m2 transects, the invertebrate fauna was collected and the substrate features were measured. The results showed that community responded to the presence of guano, cobbles, boulders, and substrate heterogeneity. The positive relationship between non-troglobitic species composition with the presence of guano reinforces the importance of food resources for structuring invertebrate cave communities in Guatemalan caves. Furthermore, the troglobitic species responded to different substrate features when compared to non-troglobitic species. For them, instead of the presence of organic matter, a higher variety of abiotic microhabitats seem to be the main driver for species diversity within a cave. The high specialization level of troglobitic organisms might be the reason why they respond differently to environmental conditions. The findings of this study highlight the importance of biological surveys for understanding cave biodiversity and give insights on how this biodiversity might be distributed within a cave. Conservation measures should keep in mind the target organisms and if such measures aim to protect a broad variety of organisms, then one should aim to preserve as many microhabitats and trophic resources as possible.

“…Although fungi in caves could colonize a variety of substrata, such as cave sediments, vermiculations on cave walls, carcasses, and droppings of troglobites or troglophiles (Nováková 2009 ), bat guano is according to Ogórek et al ( 2016 ) the most suitable substrate for fungal growth and proliferation. Since caves are usually regarded as oligotrophic, without primary production, bat guano piles are an important source of organic matter (Ferreira 2019 ). Depending on Chiroptera diet, three types of bat guanos are described.…”

Bats as flying mammals are potent vectors and natural reservoir hosts for many infectious viruses, bacteria, and fungi, also detected in their excreta such as guano. Accelerated deforestation, urbanization, and anthropization hastily lead to overpopulation of the bats in urban areas allowing easy interaction with other animals, expansion, and emergence of new zoonotic disease outbreaks potentially harmful to humans. Therefore, getting new insights in the microbiome of bat guano from different places represents an imperative for the future. Furthermore, the use of novel high-throughput sequencing technologies allows better insight in guano microbiome and potentially indicated that some species could be typical guano-dwelling members. Bats are well known as a natural reservoir of many zoonotic viruses such as Ebola, Nipah, Marburg, lyssaviruses, rabies, henipaviruses, and many coronaviruses which caused a high number of outbreaks including ongoing COVID-19 pandemic. Additionally, many bacterial and fungal pathogens were identified as common guano residents. Thus, the presence of multi-drug-resistant bacteria as environmental reservoirs of extended spectrum β-lactamases and carbapenemase-producing strains has been confirmed. Bat guano is the most suitable substrate for fungal reproduction and dissemination, including pathogenic yeasts and keratinophilic and dimorphic human pathogenic fungi known as notorious causative agents of severe endemic mycoses like histoplasmosis and fatal cryptococcosis, especially deadly in immunocompromised individuals. This review provides an overview of bat guano microbiota diversity and the significance of autochthonous and pathogenic taxa for humans and the environment, highlighting better understanding in preventing emerging diseases. Key points& Bat guano as reservoir and source for spreading of autochthonous and pathogenic microbiota & Bat guano vs. novel zoonotic disease outbreaks & Destruction of bat natural habitats urgently demands increased human awareness

Soil quality is a frequent problem hindering mine reclamation success. Much research conducted on this problem proposed the application of organic material for soil amendment. However, most of the soil amendment research only focused on the usability of organic material, such as providing nutrients, improving soil properties, and adsorbing hazardous elements. Considering that reclamation is a complex activity, we propose a comprehensive assessment of both technical and managerial aspects on the selection of organic material due to the distinctive properties of each organic material. This study aimed to assess the criteria that influence the organic material selection and determine the most suitable alternative of organic material in mine reclamation. The assessment was Analytic Hierarchy Process (AHP) with the expert choice concept. The criteria used in this study were availability, cost, usability, ease of application, and side effects. Oil palm empty fruit bunch (EFB) compost, rice husk charcoal, cattle manure, and guano were selected. This study showed that availability was the principal factor, followed by usability, cost, ease of application, and side effects. The analysis also showed that the most suitable organic material was oil palm EFB compost with a global priority of 0.363, followed by rice husk charcoal (0.244), cattle manure (0.218), and guano (0.175).
