Tier des Jahres 2016 - Der Feldhamster.

Eliomys 2016/1: 6-10.

Zusammenfassung:

Bis in die 2. Hälfte des 20. Jahrhunderts war der Feldhamster (Cricetus cricetus [LINNAEUS, 1758]) in Deutschland lokal so häufig, dass er bejagt wurde. Mittlerweile hat sich das Blatt gewendet, so dass dieser Nager nun zu den bedrohten Arten gehört.

HORNADAY, W. T. (1889)

The Extermination of the American Bison.

179 Seiten und 22 Bildtafeln. Washington, 1889

Volltext (Projekt Guttenberg): eBook

Einleitung:

It is hoped that the following historical account of the discovery, partial utilization, and almost complete extermination of the great American bison may serve to cause the public to fully realize the folly of allowing all our most valuable and interesting American mammals to be wantonly destroyed in the same manner. The wild buffalo is practically gone forever, and in a few more years, when the whitened bones of the last bleaching skeleton shall have been picked up and shipped East for commercial uses, nothing will remain of him save his old, well-worn trails along the water-courses, a few museum specimens, and regret for his fate. If his untimely end fails even to point a moral that shall benefit the surviving species of mammals which are now being slaughtered in like manner, it will be sad indeed.

Although Bison americanus is a true bison, according to scientific classification, and not a buffalo, the fact that more than sixty millions of people in this country unite in calling him a “buffalo,” and know him by no other name, renders it quite unnecessary for me to apologize for following, in part, a harmless custom which has now become so universal that all the naturalists in the world could not change it if they would.

The Red List of Mammals of South Africa, Swaziland and Lesotho 2016.

South African National Biodiversity Institute and Endangered Wildlife Trust, South Africa.

Abstract:

Of the 343 species, subspecies and subpopulations recorded from the assessment region, six were Not Evaluated (considered vagrant) and five are Extinct, leaving 331 taxa that were assessed. Overall, 57 taxa are threatened (six Critically Endangered, 20 Endangered, 31 Vulnerable) and 35 are Near Threatened. Proportional to the number of taxa assessed, this yields 17% threatened and 10% Near Threatened. This compares to 19% of taxa being threatened and 32% being Near Threatened in the previous assessment (N = 295 taxa assessed). Encouragingly, the proportion of Data Deficient listings has been significantly reduced in this revision (from 18% to 7% in 2004 and 2016 respectively) due to a combination of better information and a change in risk tolerance. While it appears that there are fewer threatened species currently, most of these changes were non-genuine, involving new information, analysis or taxonomic revision. Of the genuine changes detected thus far (N = 29), 19 (66%) are uplistings (more threatened). Thus, while more work is required to determine the overall number of genuine changes so that the Red List Index can be applied, preliminary results indicate a net worsening conservation status for mammals. Similarly, a stakeholder workshop is required to translate the Red List statuses into conservation priorities, weighing extinction risk against the context of ecological, cultural, economic and logistical factors. Finally, being Least Concern does not mean of “no concern” and we developed a watch-list categorisation to flag species that do not currently meet the criteria but may do so in the near future. Continued conservation effort is needed to enhance the recovery of all species such that they comprise evolutionarily and ecologically functional populations.

Antelope Conservation ä From Diadnosis to Action.

Conservation Science and Practice 16: 1-376.

Wiley Blackwell / Zoological Society of London. ISBN: 978-1-118-40957-2.

Beschreibung:

Antelopes constitute a fundamental part of ecosystems throughout Africa and Asia where they act as habitat architects, dispersers of seeds, and prey for large carnivores. The fascication they hold in the human mind is evident from prehistoric rock paintings and ancient Egyptian art to today's wildlife documentaries and popularity in zoos. In recent years, however, the spectacular herds of the past have been decimated or extripated over wide areas in the wilds, and urgent conservation action is needed to preserve this world heritage for generations to come.

As the first book dedicated to antelope conservation, this volume sets out to diagnose the causes of the drastic declines in antelope biodiversity and on this basis identify the most effective points of action. In doing so, the book covers central issues in the current conservation debate, especially related to the management of overexploitation, habitat fragmentation, disease transmission, climate change, populations genetics, and reintroductions. The contributions are authored by world-leading experts in the field, and the book is a useful resource to conservation scientists and practitioners, researchers, and students in related disciplines as well as interested lay people.

BLOMQVIST, L. (2017)

Reindeer Recovery.

Zooquaria 96: 20-21.

Recovery Plan:

To counteract the ongoing population decline, reintroductions will be undertaken in two Finnish Natura 2000 areas in western Finland, south of the current distribution range. The reintroductions form part of a larger, seven-year EU LIFE project on forest reindeer population management. Fifteen-hectare acclimatisation enclosures will be built in both areas to house 10 to 15 animals each. Reindeer from four participating EAZA zoos will be mixed with wild individuals captured by staff from the Natural Resources Institute Finland. Calves bred in the enclosures will then be soft-released when they are between 18 months and two years old.

Stepping-stones and dispersal flow: establishment of a meta-population of Milu (Elaphurus davidianus) through natural re-wilding.

Sci Rep. 2016; 6: 27297.
Published online 2016 Jun 7. doi: 10.1038/srep27297. PMCID: PMC4895148. PMID: 27272326

Zusammenfassung:

The Milu (Père David’s deer, Elaphurus davidianus) became extinct in China in the early 20th century but was reintroduced to the country. The reintroduced Milu escaped from a nature reserve and dispersed to the south of the Yangtze River. We monitored these accidentally escaped Milu from 1995 to 2012. The escaped Milu searched for vacant habitat patches as “stepping stones” and established refuge populations. We recorded 122 dispersal events of the escaped Milu. Most dispersal events occurred in 1998, 2003, 2006 and 2010. Milu normally disperse in March, July and November. Average dispersal distance was 14.08 ± 9.03 km, with 91.41% shorter than 25 km. After 5 generations, by the end of 2012, 300 wild Milu were scattered in refuge populations in the eastern and southern edges of the Dongting Lake. We suggest that population density is the ultimate cause for Milu dispersal, whereas floods and human disturbance are proximate causes. The case of the Milu shows that accidentally escaped animals can establish viable populations; however, the dispersed animals were subject to chance in finding “stepping stones”. The re-wilded Milu persist as a meta-population with sub-populations linked by dispersals through marginal habitats in an anthropogenic landscape.

BURTON, J., HEDGES, S. & MUSTARI, A. H (2005)

The taxonomic status, distribution and conservation of the lowland anoa Bubalus depressicornis and mountain anoa Bubalus quarlesi.

Mammal Review. 35 (1): 25 - 50.
DOI: 10.1111/j.1365-2907.2005.00048.x

Zusammenfassung:

The anoas are two species of dwarf buffalo, the lowland anoa Bubalus depressicornis and mountain anoa Bubalus quarlesi that are endemic to the island of Sulawesi, Indonesia. The classification of the subgenus Anoa within Bubalus is upheld by assessment of recent genetic and morphological research. The classification of anoas into two species is still debated, but with the absence of significant opposing evidence, this position is adopted here. 2. Information about the distribution of the two species is presented that adds to but largely supports existing reports. However, it is still uncertain whether the two putative species are sympatric or parapatric in their distribution. A review of anoa distribution from historical reports and recent field data (1990s to 2002) highlights their decline throughout Sulawesi, especially in the southern and north-eastern peninsulas. The decline has been attributed to local hunting for meat and habitat loss. Most populations are rapidly becoming fragmented, suggesting that the conservation of viable populations may eventually require management of metapopulations. 3. There is an urgent requirement for conservation efforts to: (i) protect anoas from hunting; (ii) prevent habitat loss in key sites; (iii) complete genetic studies to better determine the number of anoa taxa and Management Units and assess their distribution; and (iv) determine the status of the remaining anoa populations.
