“…The Soutpansberg (and associated Blouberg and Makgabeng) Mountain Range situated in the Savanna Biome of northern South Africa comprises a recognized Centre for Plant Endemism [32] with some 3000 plant species (of which 44 are endemic) and 1066 genera [33,34]. Faunal diversity is also high.…”

“…Variation in aspect and topography within the Soutpansberg results in strong latitudinal, longitudinal and elevational gradients in climate and vegetation. Owing to a rain shadow on the northern slopes, precipitation varies from 367 mm on the northern slopes to greater than 3000 mm (of which one third falls as mist) on the southeastern slopes [33]. Most of the Soutpansberg is covered by various types of savannah including thickets (Soutpansberg Mountain Bushveld), with small patches of temperate grasslands occurring at higher elevations (Soutpansberg Sourveld) and small patches of Mistbelt forest occurring at the bases of cliffs on the southern slopes (Soutpansberg Mistbelt Forest) [38].…”

Morphology and stable isotope analysis demonstrate different structuring of bat communities in rainforest and savannah habitats

Bats play important ecological roles in tropical systems, yet how these communities are structured is still poorly understood. Our study explores the structure of African bat communities using morphological characters to define the morphospace occupied by these bats and stable isotope analysis to define their dietary niche breadth. We compared two communities, one in rainforest (Liberia) and one in savannah (South Africa), and asked whether the greater richness in the rainforest was due to more species ‘packing’ into the same morphospace and trophic space than bats from the savannah, or some other arrangement. In the rainforest, bats occupied a larger area in morphospace and species packing was higher than in the savannah; although this difference disappeared when comparing insectivorous bats only. There were also differences in morphospace occupied by different foraging groups (aerial, edge, clutter and fruitbat). Stable isotope analysis revealed that the range of δ13C values was almost double in rainforest than in savannah indicating a greater range of utilization of basal C3 and C4 resources in the former site, covering primary productivity from both these sources. The ranges in δ15N, however, were similar between the two habitats suggesting a similar number of trophic levels. Niche breadth, as defined by either standard ellipse area or convex hull, was greater for the bat community in rainforest than in savannah, with all four foraging groups having larger niche breadths in the former than the latter. The higher inter-species morphospace and niche breadth in forest bats suggest that species packing is not necessarily competitive. By employing morphometrics and stable isotope analysis, we have shown that the rainforest bat community packs more species in morphospace and uses a larger niche breadth than the one in savannah.

Climate change constitutes a potential threat to montane biodiversity, particularly in low-altitude, tropical mountains; however, few data exist for the Afromontane taxa. In South Africa, the temperate grassland and fynbos biomes are mostly associated with the Great Escarpment and the high-lying central plateau. Varying contractions of the grassland and fynbos biomes are predicted under different climate scenarios by 2050. Animal taxa adapted to these biomes should suffer similar range declines and can be used to independently test the vegetation models. We constructed MaxEnt models from 271 unique locality records for three species of montane and submontane vlei rats that are closely associated with grassland angoniensis) due to historically documented changes from a grassland-dominated to thicket-dominated landscape.

“…Everything is connected.'' Several of the Zwifho are the sites of considerable biodiversity and home to endemic species (Hahn, 2017;Symes, Venter, & Perrin, 2000) and traditional practices have protected this biodiversity (Mutshinyalo & Siebert, 2010). For decades, traditional sacred rituals have been performed at these sites by several clans chosen by Nwali, such as the Netshidizhe clan of Zwifho zwa Thathe (sacred natural site of Thathe).…”

“Mupo Is Life”: Intergenerational Community Identity and Safeguarding Sacred Natural Sites in Limpopo Province, South Africa

Place attachments are essential for community identity, yet little is understood about sacred natural sites' salience to these attachments. A network of sacred natural sites, also known as Zwifho, is located across the Vhembe District in South Africa's Limpopo province. This qualitative case study explores and describes community members' relationships with these sacred natural sites and community responses to ecological degradation affecting these places. The study used purposive sampling to access community members who identify as protectors of the Zwifho, traditional leadership, and community members with particular environmental knowledge. The primary researcher conducted 13 in-depth qualitative interviews and conducted a thematic analysis. After data collection, archival and online materials were used to complement the description of communitybased responses to ecological degradation. Field workers verified the data and the findings were critically reviewed. The findings highlighted psychological bonds that community members have to Zwifho and have demonstrated that these sites are essential for the co-creation and transferal of intergenerational community identity.
