Conservation Refugium Value of a Large Mesa for Grasshoppers in South Africa

  title={Conservation Refugium Value of a Large Mesa for Grasshoppers in South Africa},
  author={Solomon Ali Gebeyehu and Michael John Samways},
  journal={Biodiversity \& Conservation},
A 3-year study was undertaken on and around a prominent South African mesa to determine its role for grasshoppers in a sea of grazed flatlands. The number of grasshopper species and individuals on the summit, slopes and flatlands varied significantly in relation to measured environmental variables. The summit, through inaccessibility to livestock grazing, was effectively a conservation refugium for one highly responsive grasshopper species, Orthochtha dasycnemis. There was no significant…

Feeding and Mobility Traits Influence Grasshopper Vulnerability to Agricultural Production in the Cape Floristic Region Biodiversity Hotspot
It is revealed that the fynbos biome is an important habitat for low-mobility and range-restricted species, and hence require conscious conservation efforts to conserve such species to prevent possible future biotic erosion and homogenisation in this hotspot.
Grazing and Orthoptera: a review
The over-arching principle for grazing management should be to establish a heterogeneous sward with a range of sward heights and bare earth for oviposition/basking, and the greatest diversity of habitats should provide the highest species richness.
Grasshopper assemblage response to surface rockiness in Afro‐montane grasslands
Overall, grasshopper assemblage composition, as well as familial composition, responded strongly to an elevation gradient, and not to the correlates of surface rock cover, which suggests the higher species richness in such areas is more likely a function of the significant vegetation correlates of higher surfaceRock cover.
Significant variables for the conservation of mountain invertebrates
Conserving biodiversity on mountains holds particular challenges, with topographic species beta diversity being high. In turn, conserving mountain biodiversity in the heart of a biodiversity hotspot,
Impact of wild ungulate grazing on Orthoptera abundance and diversity in subalpine grasslands
Abstract.  1. Grasslands cover approximately 40% of the Earth’s terrestrial landscape, supporting large communities of vertebrate and invertebrate herbivores. Orthoptera play an important role,
The interactive effects of fire and herbivory on understorey vegetation and its dependent fauna
This thesis demonstrates how by failing to identify mechanistic pathways, or non-linear effects, such studies are limited in their management applications.
Effect of wild ungulate density on invertebrates in a Mediterranean ecosystem
Este estudio apoya the idea of that las poblaciones with una alta densidad of ungulados perjudican a the estructura of las comunidades faunisticas, probablemente debido a the disminucion of the disponibilidad of alimentos como consecuencia ofrecer refugio a los invertebrados.


The dynamics and trophic ecology of grasshoppers (Acridoidea) in a South African savanna
Production efficiency and ecological efficiency were lower than those measured for grasshoppers in other systems, and Vegetation structure is more significant than species composition as a determinant of habitat selection within the savanna type.
Abundance and guild structure of grasshoppers (Orthoptera: Acridoidea) in communally grazed and protected savanna
The mowed area, characterised by short vegetation and low aerial cover, low greenness of grass, and low frequency of forbs, exhibited lower grasshopper abundance, species richness, and diversity than either of the grazed areas.
Land Forms and Winter Habitat Refugia in the Conservation of Montane Grasshoppers in Southern Africa
: The importance of topography in evaluation of insect conservation is discussed with reference to grasshoppers in the Natal Drakensberg Mountains, South Africa For these insects, the hilltops act as
Grasshopper assemblage response to a restored national park (Mountain Zebra National Park, South Africa)
Twelve grassland sites were sampled inside and outside the Mountain Zebra National Park (MZNP), South Africa to assess changes in grasshopper assemblages to grazing by indigenous mammals inside the
Influence of Grazing History on the Community Structure of Grasshoppers of a Mixed-Grass Prairie
Results indicated that grasshopper communities changed along habitat gradients defined by grazing history and coverage and species richness of Grasshopper species richness was greatest at sites with high richness of grasses and total coverage ofgrasses and sedges.
Monitoring of grasshopper populations in six differentially grazed pastures of native shortgrass prairie found that changes in abundance would also be accompanied by shifts in the grasshoppers species complex.
Rangeland Grasshopper (Orthoptera: Acrididae) Community Structure: A Working Hypothesis
It appears that rangeland grasshopper communities consist of facultative assemblages of species, similar to other studies in plant and insect ecology, and a positive relationship between species abundance and the number of sites collected was found at both the habitat type and valley levels.
Effect of grazing by cattle on the abundance of grasshoppers on fescue grassland.
If different intensities of grazing affect the densities of various species of grasshoppers on native fescue rangeland is determined to determine if changes in the vegetative cover should result in changes in grasshopper populations.
Dynamics of two Montana grasshopper populations: relationships among weather, food abundance and intraspecific competition
The observed annual changes in food abundance were correlated with the annual variation in weather, which indicated that the long established relationship between grasshopper densities and weather conditions does not imply population limitation by density-independent processes.
