“…Possibly, beetles were affected indirectly by changes caused by fire such as loss of cover and canopy or light increase (Sasal et al ., ). Studies on beetle colonisation showed that colonisation can take many years since fire, depending on the severity, intensity, and extension of fire (Sasal et al ., and references therein; Anjos et al ., ). Fire season might also have indirect effects related to whether the temporary removal of above ground plant resources post fire occurred when an insect species needed them.…”

“…Here, season may affect how much and which species show a positive or negative response (Swengel, ). Arthropods were shown to be able to recolonise the burned area soon after fire in the rainy season, but stayed low in abundance for at least 2 years (Anjos et al ., ). Eventually, the degree of exposure to or shelter from lethal temperature, amount of stress experienced in the post fire environment before full vegetational regrowth, suitability of post fire vegetation as habitat, season when burning occurred and ability to repopulate is a basis to predict arthropod responses not only to fire but also to grazing.…”

“…Anjos et al . () showed that the effect of fire on beetles can extend to 2 years after burn without complete recovery of species richness and composition. Darkling beetles are the most diverse and abundant group of beetles with the highest level of endemnism in arid savannahs.…”

Fire and grazing shape biodiversity in savannah landscapes. In land use management, knowing the effects of fire and grazing on biodiversity are important in order to ensure environmental sustainability. Beetles specifically are indicators of the biodiversity response to fire and grazing. A grazing exclusion and burning experiment in a split‐plot design was used in order to investigate the interacting effects of fire and wildlife grazing on biomass, diversity, and species composition of darkling beetles (Coleoptera, Tenebrionidae) over time after fire. Darkling beetle species richness and diversity were responding in a three‐way‐interaction to fire, grazing, and time after fire, whereby biomass of darkling beetles remained unaffected and species compositional changes were attributed to seasonal changes of time only. Fire on ungrazed plots had a negative effect on species diversity and richness 2 weeks and 6 months post fire, whereas fire on grazed plots had no impact on species diversity and richness. Grazing only lowered species diversity and richness 6 months after fire treatments. Results suggest that grazing overrides the effects of fire and that the similar effects caused by fire and grazing are due to niche and assemblage simplification of the habitat.

“…Current threats to their habitat that we observed in Serra do Cipó include development (e.g., roads and houses), cattle ranching, invasive plants, and frequent anthropogenic fires that alter the structure of plant and arthropod communities (Anjos et al. , Figueira et al. ) and affect the availability of suitable nest sites and food resources for Cipo Canasteros (Costa et al.…”

Home‐ranges, population densities, vocal behavior, and post‐fledging movements of Cipo Canasteros ( Asthenes luizae , Furnariidae), a rock‐specialist endemic of the highlands of eastern Brazil

Cipo Canasteros (Asthenes luizae, Furnariidae) have a fragmented and limited range restricted to the campos rupestres (rupestrian grasslands) habitat in the Brazilian highlands of the Espinhac ßo Range, and little is known about their behavior, ecology, and population biology. From March 2009 to November 2010, we monitored birds (24 banded and 22 radio-tracked) at two study sites at Serra do Cip o in the state of Minas Gerais, Brazil, to estimate their home-range sizes and population density, and describe their habitat use, natal dispersal behavior, and vocal behavior. We found an average density of 8.7 paired adults/ km² in our study areas or 22.9 paired adults/km 2 when considering only used habitats. The sex ratio was male-biased (males/total adults = 0.68), adults exhibited high site fidelity, home-ranges averaged 4.0 ha (fixed kernel 95%) or 3.5 ha (95% minimum convex polygon) in size, and both sexes defended territories yearround. We recorded four main types of songs, including two uttered more often during the breeding season. We monitored the natal dispersal of two males and one female who moved maximum distances of 1238 m, 780 m, and 1056 m, respectively, from natal areas. Our results confirm that Cipo Canasteros are restricted to the rocky-outcrop habitat of the campos rupestres. In part due to their habitat specialization, Cipo Canasteros are considered Near Threatened, but other factors contributing to their demographic fragility include the small number, and probably low survival, of females and low reproductive success due to predation and brood parasitism by cowbirds. Given these threats, along with their specialized habitat and restricted range, the future conservation of Cipo Canasteros will likely depend on the extent to which their campos rupestres habitat can be conserved.
