Nevertheless, it is less clear how the pressure of touristic activities affects the cave fauna. This study aimed to investigate the effects from tourism activities on the cave invertebrate fauna from Gruta de Lanqu&iacute;n Cave (Alta Verapaz, Guatemala). For this, quadrats were placed throughout the cave, where invertebrates were sampled and substrate features were measured. Results showed that the community structure differed among touristic and non-touristic areas of the cave and the troglobitic species are structured differently than the rest of the invertebrate community in the cave. It was detected that the pathways designated for touristic use have different substrate features than their adjacent areas. In order to maintain the conservation of the invertebrate species, several management recommendations are provided, such as determining a well-established walking path that avoids cave microhabitats and the maintenance of a supervised guided tour.</p>

Millipeds (Diplopoda), centipeds (Chilopoda) and isopods (Isopoda) are among the main components of the soil fauna. Vegetation structure represents one of the main factors influencing composition and diversity of these species that inhabit leaf litter and soil, what is particularly important in the Amazon Forest, where there are several singular vegetation types. Savannah and forest areas stand out in ferruginous hills, which represents one of the most poorly known and highly threatened ecosystems in the Amazon. However, sampling the edaphic fauna in high diversity sites represents a challenging task. Studies have shown that sampling method may influence observed patterns of diversity. From this perspective, the present study aimed to (i) investigate whether assemblages of Chilopoda, Diplopoda and Isopoda differ between vegetation types in the Amazon, (ii) indicate how biological parameters behave in such communities, (iii) identify which method or combination of methods is better suited to sample species richness and (iv) quantify the efficiency of each method regarding time of work and cost. Sampling was conducted by means of hand collection, leaf litter collection, hay-bait traps and soil sampling in four patches, two in the savannah (also called canga) and two in the forest. Richness was higher in forest habitats for Chilopoda and Diplopoda, while for Isopoda there was no significant difference. Species composition also differed between vegetation types for Chilopoda and Isopoda, but not for Diplopoda. Beta diversity between vegetation types was mainly determined by nestedness and balancing, while turnover was the main beta diversity component responsible for differences among methods. Soil sampling and hand collection added more species to the samples, therefore, this combination was the most efficient to access diversity. Our results support the hypothesis that differences in the soil cover promoted by distinct vegetation types influence the species diversity and composition of edaphic fauna. The differences were mainly determined by nestedness and balancing, indicating that the fauna sampled in the canga represents a subset of those present in the surrounding forest. In this sense, even in ecosystems with distinct vegetation types, the combination of soil and surface sampling methods is recommended. Lastly, the present study proposes a set of decision rules and a key to select the most appropriate method to sample the studied taxonomic groups.</p>
