“…One anthropogenic threat that disrupts the rupestrian grassland dynamics, not yet mentioned or included in our models and predictions, is the occurrence of anthropogenic fires. Although rupestrian grassland is a fire-prone vegetation, adapted to natural fires (Warming 1892; Silveira et al 2016;Morellato and Silveira 2018), the time, intensity and frequency of human-induced fires impose additional stresses to plants, with unforeseen effects on the entire ecosystem (e.g, Figueira et al 2016; see also Bond and Keeley 2005). Rupestrian grasslands are moisture-dependent, fire regime ecosystems, with the ignition influenced mostly by the length of the dry season and the rainfall distribution along the season (Alvarado et al 2017).…”

Rupestrian grasslands are biodiverse, evolutionary old vegetation complexes that harbor more than 5000 species of vascular plants and one of the highest levels of plant endemism in the world. Growing on nutrient-impoverished soils and under harsh environmental conditions, these mountaintop ecosystems were once spared from major human interventions of agriculture and intensive cattle ranching. However, in Brazil, rupestrian grasslands have experienced one of the most extreme land use changes among all Brazilian ecosystems, suffering from ill policies leading to intense mining activities, uncontrolled tourism, and unplanned road construction. Indeed, the discovery of large mineral reserves, the adoption of ineffective conservation policies, and, going forward, climate change, are Communicated by David Hawksworth.

“…The Serra do Cipó region comprises private areas under environmental protection (APA Morro da Pedreira) and a National Park under full protection (PARNA Serra do Cipó), as well as being part of the Espinhaço Range Biosphere Reserve (Domingues et al, 2011;Fernandes et al, 2018). At the study location, soil and vegetation are very heterogeneous, with the core landscape being a vegetation mosaic dominated by campo rupestre (rupestrian grassland) intermingled by quartzitic outcrops, surrounding forest patches, gallery forests, and mixing with dry forests and cerrado at the lower elevations (Fernandes, 2016;Silveira et al, 2016;Morellato and Silveira, 2018).…”

“…The vegetation in the studied area, at ca. 1000~1200 m a.s.l., is campo rupestre or rupestrian grasslands, a species rich mountain vegetation characterized by small herbs and shrubs associated with rocky outcrops (Silveira et al 2016;Morellato & Silveira 2018).…”

Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)?

Most angiosperms rely on animals for pollination, and insects, especially bees, are the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors, including native bees and the honeybee, on the pollination of a generalist rupestrian grassland daisy, Aspilia jolyana (Asteraceae), in Serra do Cipó, Espinhaço Mountain Range, Brazil. We recorded floral visitors and measured the seed set resulting from one single visitation. We observed a total of 442 visits, mostly by bees, with Bombus pauloensis and Apis mellifera being the most common floral visitors. Other visitors included many other species of bees, flies, hummingbirds, wasps and butterflies. Pollinators significantly increased seed set in comparison to non-visited (bagged) capitula. Moreover, there was no difference among bee species/groups in their contribution to seed set. Thus, A. jolyana benefits from its generalized pollination strategy, and frequent bee visitors, including several native species and the invasive honeybee, are equally effective pollinators for this generalist daisy of rupestrian grasslands.
