Herpetofauna of Montane Areas of Tanzania. 4. Amphibians and Reptiles of Mahenge Mountains, with Comments on Biogeography, Diversity, and Conservation

  title={Herpetofauna of Montane Areas of Tanzania. 4. Amphibians and Reptiles of Mahenge Mountains, with Comments on Biogeography, Diversity, and Conservation},
  author={Michele Menegon and Claire E. Bracebridge and Nisha R. Owen and Simon P Loader},
Abstract The Mahenge Mountains are located in the Eastern Arc Mountains, part of a global biodiversity hotspot. Few amphibian and reptile surveys have been conducted in this area, with only one study of the submontane forest zone. This previous study revealed a characteristic endemic Eastern Arc amphibian and reptile forest fauna. New studies outlined here extend the sampling time considerably and the geographical coverage (including Mselezi Forest Reserve). These studies reveal a remarkable… Expand
Species boundaries and biogeography of East African torrent frogs of the genus Petropedetes (Amphibia: Anura: Petropeditidae)
A molecular systematic study sampling populations of East African petropedetids occurring in the mountains of Tanzania provides evidence for the recognition of well-defined genetically distinct populations occurring in each mountain fragment, and further support for a new undescribed species from the Nguru Mountains is examined.

Amphibian diversity on the roof of Africa: unveiling the effects of habitat degradation, altitude and biogeography
Aim Elevational gradients and land use changes can act together as drivers of species richness and composition. Responses to these drivers can be multidirectional, and resulting patterns ofExpand
Targeted vertebrate surveys enhance the faunal importance and improve explanatory models within the Eastern Arc Mountains of Kenya and Tanzania
Aim Detailed knowledge of species distributions, endemism patterns and threats is critical to site prioritization and conservation planning. However, data from biodiversity inventories are stillExpand
The Reptiles of the Uzungwa Scarp Forest Reserve (User): An Updated Checklist with Notes on Dagger-Tooth Vine Snake Xyelodontophis uluguruensis
ABSTRACT Uzungwa Scarp Forest Reserve (USFR) is one of the largest continuous forests within the Eastern Arc Mountains that has not been surveyed adequately from a herpetological perspective. AExpand
Globally Threatened Biodiversity of the Eastern Arc Mountains and Coastal Forests of Kenya and Tanzania

The first endemic West African vertebrate family – a new anuran family highlighting the uniqueness of the Upper Guinean biodiversity hotspot
Based on molecular and morphological distinctiveness, the West African torrent-frog Odontobatrachus natator is allocated to a newly described anuran family, highlighting the Upper Guinean forests as an outstanding, but highly endangered biodiversity hotspot. Expand
Light shines through the spindrift--phylogeny of African torrent frogs (Amphibia, Anura, Petropedetidae).
Interestingly, the three geographic clades do not form a monophyletic group with respect to closely related families Pyxicephalidae and Conrauidae and therefore require taxonomic changes and are placed in the new genus Odontobatrachus gen. nov. Expand
The Dynamics of Re-introduced Kihansi Spray Toad Nectophrynoides asperginis and other Amphibians in Kihansi Gorge, Udzungwa Mountains, Tanzania
The dynamics of the reintroduced Kihansi spray toad Nectophrynoides asperginis and other amphibian species that occur in the KihANSi gorge, UdzungwaMountains were studied and suggest low survivorship of theintroduced KST. Expand
Behavioral and Morphological Divergence of Sympatric Morphotypes of Leptopelis flavomaculatus (Anura, Arthroleptidae) in Northeastern Tanzania
The results show differences in the call durations, dominant frequencies, mean call intensities, as well as in size (body length and body mass) of the two vocally active color morphs of this species. Expand


Herpetofauna of Montane Areas of Tanzania. 3. Amphibian Diversity in the Northwestern Eastern Arc Mountains, with the Description of a New Species of Arthroleptis (Anura: Arthroleptidae)
Abstract Amphibians of the Eastern Arc Mountains are poorly known, apart from those of the East Usambara, Uluguru, and Udzungwa Mountains. Here, we detail specimens collected in the northwesternExpand
Herpetofauna of Mahenge Mountain, Tanzania : a window on African biogeography
The results show significant differences between the two areas, reflecting large altitudinal turnover in species between the widespread lowland fauna and the montane fauna in Tanzania. Expand
The Nguru mountains of Tanzania, an outstanding hotspot of herpetofaunal diversity
The results, documenting the high species richness and the outstanding number of putative endemics of the forests, strongly highlight the biological importance of the South Nguru Mountains and place them among the most important sites for the conservation of herpetofauna in Africa. Expand
The biological importance of the Eastern Arc Mountains of Tanzania and Kenya
Abstract The Eastern Arc Mountains are renown in Africa for high concentrations of endemic species of animals and plants. Thirteen separate mountain blocks comprise the Eastern Arc, supporting aroundExpand
Within and between‐site distribution of frog species on the Udzungwa Plateau, Tanzania
This study provides baseline information for monitoring the anuran community at Mtele over time for changes in numbers, species composition and diversity that may be indicative of population declines. Expand
Three new species of Callulina (Amphibia: Anura: Brevicipitidae) highlight local endemism and conservation plight of Africa's Eastern Arc forests
The high local endemism of Callulina in the northern part of the Eastern Arc Mountains is revealed, raising further conservation concern for this group of amphibians. Expand
Altitudinal species turnover in southern Tanzania shown by anurans: Some zoogeographical considerations
A transect was used to investigate the pattern of altitudinal species turnover shown by the rich fauna of frogs and toads in southeastern Tanzania, and to compare the pattern with those shown bytransects taken further south, suggesting a need for re‐evaluating the common practice of including all sub‐Saharan Africa in a single Afrotropical Region.
