Interactions between land use, taxonomic group and aspects and levels of diversity in a Brazilian savanna: implications for the use of bioindicators

<p>The study was carried out&nbsp;in&nbsp;the&nbsp;Tri&acirc;ngulo&nbsp;Mineiro region of Minas Gerais state, covering the municipalities of&nbsp;Uberl&acirc;ndia, Monte&nbsp;Alegre,&nbsp;and Nova Ponte,&nbsp;in&nbsp;south-eastern&nbsp;Brazil.&nbsp;We&nbsp;conducted the study&nbsp;in&nbsp;five habitat types,&nbsp;comprising&nbsp;two&nbsp;natural&nbsp;habitats&nbsp;(savanna&nbsp;and&nbsp;semideciduous forest),&nbsp;and three anthropogenic land-uses:&nbsp;cattle pastures (planted with&nbsp;introduced&nbsp;Urochloa&nbsp;grasses),&nbsp;soy fields (where sampling took place when plants were at the vegetative phase)&nbsp;and&nbsp;&nbsp;plantations&nbsp;of&nbsp;Eucalyptus&nbsp;trees&nbsp;(&ge;&nbsp;6&nbsp;yrs&nbsp;old).&nbsp;Ants&nbsp;and beetles&nbsp;were sampled&nbsp;at&nbsp;the same&nbsp;40 sites (8&nbsp;replicates&nbsp;per&nbsp;land use), and birds&nbsp;at&nbsp;30 sites (6&nbsp;replicates&nbsp;per land use), only some of which were the same as for ants and beetles.&nbsp;</p> <p>Ants&nbsp;that forage on ground&nbsp;and&nbsp;dung beetles&nbsp;were sampled&nbsp;using&nbsp;pitfall traps. Sampling took&nbsp;place in&nbsp;November&nbsp;and December&nbsp;(early wet season)&nbsp;2017.&nbsp;In each site, eight traps were&nbsp;installed with traps located at the corners of a 100&times;100&nbsp;m square, and at the mid-points of&nbsp;the sides of the square,&nbsp;keeping a&nbsp;minimum distance of 50&nbsp;m between&nbsp;any two&nbsp;traps.&nbsp;All traps were at least 75 m distant from the edge of the respective land&nbsp;use.&nbsp;Traps were plastic containers (19 cm&nbsp;diam, 11 cm height) filled with 150 ml of a saline solution and detergent. Each trap had a wire hoop suspended over it to accommodate a small (4 cm&nbsp;diam, 4 cm height) plastic container for holding a dung bait. We used a 20 cm&nbsp;diameter plastic cover supported by three sticks to protect traps from rain. Traps were baited with&nbsp;~40 g of a mixture of pig dung and human&nbsp;faeces&nbsp;(4:1 proportion)&nbsp;and left in the field for 48-hrs.</p> <p>Birds were surveyed&nbsp;using&nbsp;20-min point counts in the rainy season (November 2017 to March 2018). At each site,&nbsp;five sampling points were established, 200 m distant from each other. All surveys started at sunrise (about 6 a.m.), and all species seen or heard from each point were recorded. Each sampling site was&nbsp;re-surveyed&nbsp;in the&nbsp;following&nbsp;dry season (April to&nbsp;October to 2018); however, for logistic reasons we were unable to re-survey the plantation sites.&nbsp;</p> <p>Ant&nbsp;and dung beetle&nbsp;species were identified to&nbsp;species or morphospecies&nbsp;by comparison with named species in the Zoological Collection at the Federal University of&nbsp;Uberl&acirc;ndia&nbsp;(UFU)&nbsp;or&nbsp;with&nbsp;specialist assistance from Fernando Vaz de Mello, respectively.&nbsp;Vouchers of&nbsp;all&nbsp;species have been deposited&nbsp;at&nbsp;UFU&acute;s Zoological Collection.&nbsp;Birds were identified directly in the field and species&nbsp;names follow the checklist produced by the Brazilian Ornithological Records Committee.</p> <p>We classified species&nbsp;functionally&nbsp;based on&nbsp;primary diet, foraging&nbsp;location&nbsp;and/or&nbsp;behaviour, and body size,&nbsp;as&nbsp;these&nbsp;traits&nbsp;are known to be sensitive&nbsp;to habitat modifications&nbsp;and of importance for the ecosystem services provided by ants, birds, and dung beetles.</p> <p>Ant species were classified according to their diet as&nbsp;predators,&nbsp;fungivores,&nbsp;nectarivores&nbsp;or omnivores,&nbsp;and according to their main foraging location&nbsp;as arboreal, epigeal&nbsp;(aboveground)&nbsp;or hypogeal&nbsp;(in soil and litter), based on&nbsp;information provided by Brown (2000) and Silvestre&nbsp;et al.&nbsp;(2003). Species were&nbsp;further&nbsp;classified&nbsp;into four body size categories based on&nbsp;our&nbsp;measurements of body length&nbsp;(Weber&acute;s length;&nbsp;Brown,&nbsp;1953)&nbsp;of&nbsp;1-5&nbsp;ant workers&nbsp;per species:&nbsp;1 (&lt; 0.75&nbsp;mm),&nbsp;2 (0.75-1.74&nbsp;mm),&nbsp;3 (1.75-3&nbsp;mm),&nbsp;and 4 (&gt; 3 mm).</p> <p>Dung beetles were classified as coprophagous, necrophagous, frugivore, generalist or predator, according to the type of food resource each species is most&nbsp;often&nbsp;attracted to. This classification was based on over 30 years of field experience&nbsp;throughout Brazil&nbsp;by one of the authors&nbsp;of this study&nbsp;(FVM),&nbsp;who used multiple types of baits&nbsp;(e.g., carcasses, fruits, faeces)&nbsp;to attract and collect dung beetles, and/or on literature information.&nbsp;Although information about the &ldquo;attractiveness&rdquo; of different types of baits&nbsp;to&nbsp;dung beetles (used here as a proxy for primary diet)&nbsp;was&nbsp;not obtained&nbsp;directly&nbsp;in the sites of the present study, it is importat to note that we are not aware of&nbsp;any evidence&nbsp;of geographic or habitat&nbsp;variation in bait preference&nbsp;among tropical species of dung beetles.&nbsp;Dung beetles&nbsp;were also&nbsp;classified&nbsp;according&nbsp;to&nbsp;their&nbsp;foraging&nbsp;behaviour as:&nbsp;telecoprid&nbsp;(species that make a dung ball and roll it away for burial),&nbsp;paracoprid&nbsp;(species that store dung in tunnels dug immediately below the dung&nbsp;source),&nbsp;or&nbsp;endocoprid&nbsp;(species living within or immediately below the dung, without moving it).&nbsp;For this,&nbsp;we used&nbsp;the database of the&nbsp;Zoological Collection&nbsp;of&nbsp;the Federal University&nbsp;of&nbsp;Mato Grosso (UFMT).&nbsp;Whenever sample sizes&nbsp;allowed, 30&nbsp;individuals from each species&nbsp;were weighed for determination of body mass&nbsp;(following Almeida et al.,&nbsp;2011), and species were&nbsp;classified&nbsp;according to the following ordinal scale: 1&nbsp;(&lt;&nbsp;10&nbsp;mg);&nbsp;2&nbsp;(10-99&nbsp;mg);&nbsp;3&nbsp;(100-300&nbsp;mg);&nbsp;and&nbsp;4&nbsp;(&gt;300&nbsp;mg).</p> <p>Each bird&nbsp;species&nbsp;was&nbsp;classified according to&nbsp;its&nbsp;primary diet as&nbsp;frugivores granivore, insectivore, nectarivore,&nbsp;carnivore,&nbsp;detritivore,&nbsp;or omnivore,&nbsp;and according to the main&nbsp;foraging&nbsp;location&nbsp;as&nbsp;ground, understory/shrubby vegetation, or tree canopy, based on&nbsp;the&nbsp;Wilman&nbsp;et al.&nbsp;(2014) database and&nbsp;our&nbsp;own&nbsp;field experience.&nbsp;Using these&nbsp;same sources,&nbsp;we obtained information&nbsp;on&nbsp;mean body weights of each&nbsp;species and&nbsp;assigned&nbsp;them&nbsp;to one of&nbsp;five&nbsp;size categories: 1-&nbsp;(&lt;15 g);&nbsp;2&nbsp;(15-39 g);&nbsp;3&nbsp;(40-199&nbsp;g);&nbsp;4&nbsp;(200-599 g);&nbsp;and 5&nbsp;(&gt;&nbsp;600 g).</p>
