SCHMIDT, A. D. (2002)

The herpetofauna  of the Langjan Nature Reserve (Limpopo Province, Republic of South Africa) (Amphibia, Reptilia).
Die  Herpetofauna  des Langjan-Naturreservates (Provinz Limpopo, Republik Südafrika) (Amphibia,  Reptilia).  

HERPETOZOA  15 (3/4): 121-135.

Kurzfassung:

Das Langjan-Naturreservat ist ein 4774 ha großes Schutzgebiet in der Limpopo Provinz Südafrikas, 130 km nördlich der Provinzhauptstadt Pietersburg gelegen. Während einer Feldstudie von Januar bis April 1998 und drei kürzeren Aufenthalten zwischen 1999 und 2001 konnten innerhalb des Schutzgebietes insgesamt 43 Reptilien- (3 Schildkröten, 23 Eidechsen, 17 Schlangen) und 7 Amphibienarten nachgewiesen werden. Die Anzahl der aus dem Gebiet bekannten Formen erhöht sich damit auf 47 bei den Reptilien und 10 bei den Amphibien. Die von der Autorin im Untersuchungsgebiet nachgewiesenen Arten werden hinsichtlich ihrer relativen Häufigkeit, ihrer allgemeinen Lebensraumansprüche und Verbreitung im Reservat charakterisiert. Neun weitere, bisher nur außerhalb der Reservatsgrenzen nachgewiesene Reptilienarten kommen wahrscheinlich auch im Reservat selbst vor. Die Fundortbeschreibungen ausgewählter Formen werden durch ökologische, zoogeographische oder taxonomische Hin-weise ergänzt. Vier Arten {Psammobates oculiferus, Typhlosaurus lineatus subtaeniatus, Scelotes limpopoensis albiventris, Colopus wahlbergii wahlbergii) verdienen aufgrund ihrer eingeschränkten Gesamtverbreitungsgebiete bzw. Seltenheit besondere faunistische Beachtung.

GRIFFIN, M. (2003)

Annotated Checklist and Provisional Conservation Status of Namibian Reptiles.

168 Seiten. Windhoek. ISBN

Volltext: http://podarcis.de/AF/Bibliografie/BIB_4908.pdf

Abstract:

An annotated checklist of indigenous and potentially indigenous Namibian terrestrial, aquatic and marine reptiles is presented. The purpose is to serve as an interim description of Namibian reptile diversity, to establish a taxonomic and biogeographical baseline, and as a preliminary review of the conservation status of Namibian reptiles. Two hundred and forty species of indigenous reptiles are presently known to occur in Namibia. These species comprise an array of approximately 265 described (but not always recognized) taxa, several of which are probably unwarranted.  Species accounts are presented for all these species. Four accounts are for new species currently being described. Nineteen species have not yet been recorded from Namibia, but are expected to (accounts given) and another 6 species are less likely to occur (no accounts given).  Full accounts are given for the 17 species which have been formally recorded in the past, but the lack of recent evidence suggests that the species is now locally extinct, the original report erroneous, or the species’ occurred  as vagrants. Four additional species had been included on various published lists in the past, but have never been formally documented, no specimens are known to exist, and it is unlikely that the species would occur today even as vagrants (no accounts given). In total, 276 species-accounts are presented.  Each account cites the original reference and type locality for each taxon, and a short description of the Namibian distribution.  Emphasis is placed on Namibian and international legal and conservation status.  Eighty-five species (33%) were found to be of local conservation concern.  Gaps in knowledge (e.g. taxonomy, biogeography, and conservation status), where future research should be directed, are noted.

HAACKE, W. D. (1984)

The Herpetology of the Southern Kalahari Domain.

Supplement to Koedoe 1984: 171-186.

Volltext: https://www.researchgate.net/publication/47296195_The_Herpetology_of_the_Southern_Kalahari_domain

Abstract:

The herpetofauna of the southrn Kalahari has mixed affinities, as this area lies on a rainfall gradient in a critical area where a transition between the arid south-west and the moister northe-east takes place. As the variation in substrate type is relatively limited, the effect of the rainfall gradient appears to influence and determine the range limits of many taxa in which of 55 recorded reptiles, 11 western taxa overlap or form a parapatric zone with 25 eastern taxa, while the remaining taxa are endemic or wide-ranging.

DOLLINGER, P. (1971)

Tod durch Verhalten bei Zootieren.

Death through behaviour in zoo animals.

Vet. med. Diss. Zürich.
Juris Verlag Zürich. 229 Seiten, 26 Tabellen, 11 Grafiken, 15 Fotos

Tierpsychologische Abteilung des Zoologischen Instituts, Prof. Dr. H. Hediger, und
Veterinär-Pathologisches Institut, Prof. Dr. H. Stünzi, der Universität Zürich
Zoo Zürich

Zusammenfassung:

Die vorliegende Arbeit befasst sich mit dem von HEDIGER (1956) geschaffenen Begriffs des Todes durch Verhalten (TdV) bei Zootieren. Dieser Terminus wird erstmalig definiert, wobei zwischen direktem und indirektem TdV unterschieden wird (pp. 13-14).

Aus der Literatur werden Angaben über die Häufigkeit der traumatischen Todesursachen – welche sich weitgehend mit den direkt durch Verhalten verursachten Todesfällen decken – in verschiedenen Zoos und aus verschiedenen Pathologischen Instituten zusammengestellt (pp. 15-23).

Um sichere Anhaltspunkte über die Bedeutung des TdV zu erhalten, wurden die Todesfälle im Säugetier-, Vogel- und Reptilienbestand des Zürcher Zoos von 1954-1969 bearbeitet (pp.24-47). Dabei zeigte es sich, dass über die Frequenz des indirekten TdV retrospektiv nichts ausgesagt werden kann, dass jedoch der direkte TdV bei Säugetieren und Vögeln die wichtigste Todesursache darstellt (23.4 resp. 29.4 % der Todesfälle), während er bei Reptilien relativ unbedeutend ist.

Eine Zusammenfassung der Ergebnisse aus dem Zürcher Zoo findet sich auf Seite 48.

Den breitesten Raum nimmt eine analytische Untersuchung über das Phänomen des TdV ein (pp. 49-152). Es wird ein Schema der am TdV beteiligten psychologischen, ökologischen, ethologischen und pathologischen Komponenten gegeben (p.49) und deren Beziehungen untereinander werden anhand einiger exemplarischer Beispiele dargestellt (pp. 49-53).

Anschliessend wird detailliert auf die einzelnen Komponenten eingegangen, wobei auf die auslösenden Faktoren (psychologische und ökologische Momente) besonderes Gewicht gelegt wird, da deren Kenntnis Voraussetzung und bester Ansatzpunkt für eine wirksame Prophylaxe des TdV ist (pp- 53-126).

Von den zum  Tod führenden Verhaltensweisen (pp. 127-144) werden Automutilation, Inanition und Kannibalismus sowie das Syndrom des Ausbrechens, Ausreissens und Entweichens näher untersucht.

Die den Tod bewirkenden Läsionen und Funktionsstörungen werden nur der Vollständigkeit halber gestreift (pp. 144-152) und schliesslich werden noch einige grundsätzliche Bemerkungen zur Prophylaxe des TdV gemacht (pp. 153-156).

Den Abschluss des Textteils bildet die umfangreiche Kasuisitik aus den Zoos von Zürich und Mulhouse (pp.157-196) und die Bibliographie (pp. 200-216).

Abstract:

The problem of “death through behaviour” (death caused by effects of behaviour) of zoo animals (HEDIGER,l 1956) is discussed in the present paper.

A definition of this term is provided recognising direct and indirect cause of death through behaviour (pp. 13-14).

Reports from various pathology-laboratories and zoos dealing with traumatic deaths which could be contributed to animal behaviour are reviewed (pp. 15-23).

In order to emphasize the importance of above phenomenon, deaths of mammals, birds and reptiles which occurred at Zurich zoo between 1954 and 1969 were analysed (pp.24-47). The frequency of deaths caused indirectly through behaviour could not be recognised. Behaviour as direct cause of death occurred most frequently in mammals and birds (23.4 and 29.4 % respectively), but was relatively unimportant in reptiles.
The results of the survey from Zurich zoo are summarized on page 48.

The phenomenon of death through behaviour is analysed (pp. 49-152). The psychological, ethological, ecological and pathological factors and their interrelations participating in the occurrence of deaths through behaviour are illustrated on a scheme with some practical examples (pp. 49-53).

All components are discussed each in detail with particular attention to the triggering factors (psychological and ecological moments) in order to gain knowledge and basis for prophylaxis (pp- 53-126).

Some behavioural pattern leading to death, such as automutilation, inanition, cannibalism and also the occurrence of break-outs, tearings and escapes are discussed (pp. 127-144).

The lesions and functional disturbances were only briefly noted (pp. 144-152) and general remarks are given on prophylaxis (pp. 153-156).

In the final chapter case histories are listed from the zoos of Zurich and Mulhouse/France (pp.157-196) and references of the literature are provided (pp. 200-216).

UNEP-WCMC (2009)

Review  of  non-CITES  reptiles that are known or likely to be in international trade.

A Report to the European Commission.
86 Seiten. UNEP-WCMC, Cambridge.

Einleitung:

This report was conducted in order to identify reptile species which are currently not listed in CITES or the EU Wildlife Trade Regulations, but for which there is evidence of international trade, drawing attention particularly to species which are globally threatened and/or appear to be commonly in trade within the European  Union. Based  on  a  survey  of  24  websites offering reptiles for sale within the EU, 75 species were identified as being commonly in trade (advertised  on  five  or  more  websites) and a further 14 species were less common in trade (advertised on fewer than five websites) but were considered globally threatened in the IUCN Red  List.  In-depth  reviews  were conducted for ten species. The remaining species may besuitable for in-depth reviews in subsequent reports. This work follows-on from two reports on trade in non-CITES amphibians. The first report, a document for SRG 42, provided an overall analysis of amphibian species that are not listed in CITES but for which regional or international trade was considered to be a major threat in the 2007 IUCN  Red  List;  in-depth  reviews were undertaken for 13 species. The second report, SRG 46/8, included in-depth reviews for a further 20 species.

CAMPOS SOARES de VASCONCELOS, R. (2010)

Integrative Approaches to the Systematics and Conservation of the Reptiles of the Cape Verde Islands.

PhD Thesis. Departamento de Biologia Faculdade de Ciências da Universidade do Porto

Volltext: http://www.scvz.org/pdf/TeseRVLowRes_ii.pdf

Summary:

Two of the main sensitivities of Conservation Biogeography are the inadequacies in taxonomic and chorological data, the so-called Linnean and Wallacean shortfalls, respectively. These shortfalls increase in the more remote areas such as oceanic islands. This thesis contributed to dilute those shortfalls in one of those remote areas, the Cape Verde Islands, for one of its least studied group, the reptiles.The specific goals of this thesis were related to answering to what diversity occurs there and to address putative biogeographic factors that explain why diversity is unevenly distributed. Then, it is aimed to answer where this biodiversity can be found and, based on all the gathered data, to plan how to better protect it at different levels.

First, the phylogeographic patterns of terrestrial reptiles were studied to identify an introduced agamid and cryptic endemic taxa of the three genera (Hemidactylus, Tarentola and Chioninia) and to clarify their systematics. The new introduced taxon in Cape Verde was identified as Agama agama. Also, some endemic subspecies were upgraded to the specific status and three new cryptic species (Hemidactylus lopezjuradoi, Tarentola bocageiand T. fogoensis) and subspecies (Chioninia vaillanti xanthotis, C. spinalis boavistensis and C. s. santiagoensis) were described using an integrative approach combining morphological, genetic and population analyses. These studies highlighted the usefulness of integrative datasets in the fields of Taxonomy and Phylogeography and how they can improve the performance of taxa estimations. In addition, the origin of the introduced Agama and the colonisation patterns of the endemic taxa were inferred and several historical and environmental factors, such as the Pleistocene sea-level falls and altitude, were related with the uneven distribution of diversity at intraspecific level. Low intraspecific divergence between reptile lineages of the same island has been explained by the recent volcanic activity and high ecological stress that could lead to population extinctions, and the low habitat diversity within some islands that could restrain opportunities for allopatric diversification.

Secondly, extensive sampling and bibliographic chorological data were compiled to produce and updated distribution atlas for all taxa addressing doubtful or erroneous records and to develop predictive maps of occurrence based on ecological niche-based models for most of the endemic taxa. This data also allowed the detection of the wide-spreading of the introduced H. angulatus in Santiago and Boavista and the colonisation of two new islands by the exotic H. mabouia. In addition, it allowed updating the conservation status for the endemic taxa showing that around half of them are threatened under the IUCN criteria and that the most frequent classifying criterion was related to restricted geographic range. The most pervasive threats identified are related to natural disasters, as droughts and volcanic activity, intrinsic factors, such as low population densities and restricted range, and introduced species.

Finally, this work also demonstrated how ecological niche-based models are useful tools to infer ranges on relatively under-sampled and remote areas with high accuracies and how they can be applied to conservation, maximizing efficiency of reserve designs. Results depicted that in Santa Luzia, Branco, Raso, Sal, Boavista, Maio and Rombos designation of new protected areas is not a priority since the ones that are going to be implemented will reach the conservation targets for all identified evolutionary significant units of those islands and islets. On the other hand, new or modified reserves should be implemented on the remaining islands to cover all identified lineages of Cape Verdean reptiles. This measure is especially important in Fogo and Brava, where no planning unit selected by the area prioritisation scenarios is within the protected areas limits and no protected area is planned, respectively.
Altogether, this work exemplifies the usefulness of integrating different disciplines to more effectively allowing systematic conservation planning of biodiversity.
