The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -

Misgund Orchards
MISGUND ORCHARDS ENVIRONMENTAL AUDIT 2014 Grey Rhebok Pelea capreolus Prepared for Mr Wayne Baldie By Language of the Wilderness Foundation Trust In March 2002 a baseline environmental audit was completed by Conservation Management Services. This foundational document has served its purpose. The two (2) recommendations have been addressed namely; a ‘black wattle control plan’ in conjunction with Working for Water Alien Eradication Programme and a survey of the fish within the rivers was also addressed. Furthermore updated species lists have resulted (based on observations and studies undertaken within the region). The results of these efforts have highlighted the significance of the farm Misgund Orchards and the surrounds, within the context of very special and important biodiversity. Misgund Orchards prides itself with a long history of fruit farming excellence, and has strived to ensure a healthy balance between agricultural priorities and our environment. Misgund Orchards recognises the need for a more holistic and co-operative regional approach towards our environment and needs to adapt and design a more sustainable approach. The context of Misgund Orchards is significant, straddling the protected areas Formosa Forest Reserve (Niekerksberg) and the Baviaanskloof Mega Reserve. A formidable mountain wilderness with World Heritage Status and a Global Biodiversity Hotspot (See Map 1 overleaf). Rhombic egg eater Dasypeltis scabra MISGUND ORCHARDS Langkloof Catchment MAP 1 The regional context of Misgund Orchards becomes very apparent, where the obvious strategic opportunity exists towards creating a bridge of corridors linking the two mountain ranges Tsitsikamma and Kouga (south to north). The environmental significance of this cannot be overstated – essentially creating a protected area from the ocean into the desert of the Klein-karoo, a traverse of 8 biomes, a veritable ‘garden of Eden’. -

Using Spatially Explicit Call Data of Anhydrophryne Ngongoniensis to Guide Conservation Actions
Using spatially explicit call data of Anhydrophryne ngongoniensis to guide conservation actions M Trenor orcid.org/0000-0002-0682-2262 Dissertation submitted in fulfilment of the requirements for the Masters degree in Zoology at the North-West University Supervisor: Prof C Weldon Co-supervisor: Dr J Tarrant Graduation May 2018 25747339 Abstract It’s been barely 25 years since the Mistbelt Chirping Frog (Anhydrophryne ngongoniensis) was discovered. This secretive amphibian occurs only in the so-called mistbelt grasslands and montane forest patches of south-central KwaZulu-Natal, South Africa and is restricted to an area of occupancy of just 12 square kilometers. This species’ habitat is severely fragmented due to afforestation and agriculture and only two of the remaining populations are formally protected. The species occurs mostly on fragmented grassland patches on forestry land, and any conservation strategies should include the management practices for the landowners. Updated density estimates and insight into habitat utilization are needed to proceed with conservation strategy for the species. Like many other frogs, this species is cryptic in its behaviour, making mark-recapture surveys prohibitively challenging. Audio transects have been used previously, but are dependent on surveyor’s’ experience, hindering standardization. Using automated recorders, in a spatially explicit array with GPS synchronization, one can confidently estimate the density of calling males and reveal the estimated locations of calling males, thus providing insight into their occupancy. We surveyed nine historic sites and detected the species at five of the sites in either isolated grassland patches or indigenous Afromontane forest. We successfully employed the spatially explicit catch recapture (SECR) method at three of the sites using Wildlife Acoustics™ Song Meters with extended microphones in an array. -
Extinction of Threatened Vertebrates Will Lead to Idiosyncratic Changes in Functional Diversity Across the World ✉ Aurele Toussaint 1 , Sébastien Brosse 2, C
ARTICLE https://doi.org/10.1038/s41467-021-25293-0 OPEN Extinction of threatened vertebrates will lead to idiosyncratic changes in functional diversity across the world ✉ Aurele Toussaint 1 , Sébastien Brosse 2, C. Guillermo Bueno1, Meelis Pärtel 1, Riin Tamme 1 & Carlos P. Carmona 1 1234567890():,; Although species with larger body size and slow pace of life have a higher risk of extinction at a global scale, it is unclear whether this global trend will be consistent across biogeographic realms. Here we measure the functional diversity of terrestrial and freshwater vertebrates in the six terrestrial biogeographic realms and predict their future changes through scenarios mimicking a gradient of extinction risk of threatened species. We show vastly different effects of extinctions on functional diversity between taxonomic groups and realms, ranging from almost no decline to deep functional losses. The Indo-Malay and Palearctic realms are par- ticularly inclined to experience a drastic loss of functional diversity reaching 29 and 31%, respectively. Birds, mammals, and reptiles regionally display a consistent functional diversity loss, while the projected losses of amphibians and freshwater fishes differ across realms. More efficient global conservation policies should consider marked regional losses of func- tional diversity across the world. 1 Institute of Ecology and Earth Sciences, University of Tartu, Tartu, Estonia. 2 Université Paul Sabatier, CNRS, IRD, UMR5174 EDB (Laboratoire Évolution et ✉ Diversité Biologique), Toulouse, France. email: [email protected] NATURE COMMUNICATIONS | (2021) 12:5162 | https://doi.org/10.1038/s41467-021-25293-0 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-021-25293-0 he loss of global biodiversity is accelerating throughout the with different key aspects of their ecology and their life-history Tworld1 triggering the sixth mass extinction crisis2. -

Rigorous thesis. Masaryk University, Brno: 82 pp. Anotace: The phylogenetic relationships of brevicipitid frogs are poorly understood. The first morphology phylogeny for genus Breviceps is presented, including representatives of 8 species (n= 84), and 1 hemisotid genus Hemisus (n=4) as outgroup. The total of 25 morphological characters (synapomorphies) were analysed using Maximum parsimony method - Paup 4.010b. Analysis of the data are consistent with the paraphyly of the Breviceps and forms two sister clades within the genus. Well supported is a monophyly of the clade B. namaquensis and B. macrops grouped with B. rosei as a sister taxon. This group forms a sister clade to the B. gibbosus, B. fuscus and B. verrucosus monophyletic group. Other two species B. adspersus and B. montanus forms a sister clade to this second group. Morphometric study (diameter of the eye) is also described. Breviceps namaquensis and B. macrops possess the biggest eye diameter of the genus and also their six morphological adaptations are presented in this study.
