Abstract The critically endangered Western Derby eland Taurotragus derbianus derbianus, representing < 200 wild individuals, undoubtedly needs a coordinated conservation programme. To promote the survival of this subspecies, a single worldwide semi-captive population was established in Senegal in 2000, with one male and five female founders transferred from the Niokolo Koba National Park. To determine a long-term conservation strategy, we used demographic and pedigree data based on continuous… Expand
Conservation genetics of the Western Derby eland (Taurotragus derbianus derbianus) in Senegal: integration of pedigree and microsatellite data
TLDR
The overall results for genetic parameters were comparable with other breeding programmes for endangered ungulates, and the use of comprehensive molecular data to refine the studbook and to correct relatedness of founders and assign the missing paternities is suggested. Expand
Chinko/Mbari drainage basin represents a conservation hotspot for Eastern Derby eland in Central Africa
One of the largest of antelopes, Derby eland (Taurotragus derbianus), is an important ecosystem component of African savannah. While the western subspecies is Critically Endangered, the easternExpand
Comparison of divergent breeding management strategies in two species of semi-captive eland in Senegal
TLDR
The parameters of genetic polymorphism indicated much lower genetic diversity in Western Derby elands compared to Cape elands, and the coefficient of inbreeding was low in both species, and it is hypothesized that this could be a positive effect of strict population management of Western Derbyelands, which, despite the loss of genetic diversity, minimizes inbreeding.

Drivers of diet selection of critically endangered Western Derby eland during the food shortage period within conservation breeding in Senegal
TLDR
It is indicated that large browsers during periods of food shortage must cope with inappropriate chemical composition in regard to nutrition and seek to alleviate them not only by diversification of plant species in the diet, but also by adjusting chemical diet quality as a whole. Expand
Spatially restricted occurrence and low abundance as key tools for conservation of critically endangered large antelope in West African savannah
TLDR
The age-specific vital rates indicate adult males as the most vulnerable; suggesting either an increase in the large predators’ population, livestock encroachment pressure, and/or poaching; imply that targeted monitoring with science-based interpretation may bring forward strong conservation solutions to the protected area management decision-makers.

Cast away on Mindoro island: population dynamics of the critically endangered tamaraw (Bubalus mindorensis) at Mounts Iglit-Baco Natural Park
TLDR
This study highlights that beyond the encouraging results of a continuous growth over the last two decades, the MIBNP tamaraw population remains subject to uncertainty of its long term viability. Expand
Feeding Rank in the Derby Eland: Lessons for Management
TLDR
It is concluded that the position in the hierarchy was related to the actual condition, reflecting the resource holding potential of individuals, and effective supplementary feeding should be provided in excess amounts to enable younger and weaker individuals in need to benefit from it, despite their lower positions inThe hierarchy. Expand
Does Supplemental Feeding Affect Behaviour and Foraging of Critically Endangered Western Giant Eland in an ex situ Conservation Site?
TLDR
Food supplementation facilitates the animals overcoming unfavourable conditions or alleviates stress with additional rest, and could therefore assist as a conservation intervention to enhance fitness. Expand
Does supplemental feeding affect behaviour and foraging of critically endangered western giant eland in an ex situ conservation site?
The western giant eland (Tragelaphus derbianus derbianus) needs appropriate management for its survival. We measured the effects of supplemental food on activity and browsing patterns during seasonsExpand
Spatially Restricted Occurrence and Low Population Abundance Estimates as Key Tools for the Conservation of the Critically Endangered Large Social Antelope in West African Savannah
Background: The effective conservation of mammals on the brink of extinction requires an integrated socio-ecological approach, yet the knowledge of updated species distribution, population size,Expand

Population ecology and conservation of endangered megafauna: the case of European bison in Białowieża Primeval Forest, Poland
TLDR
It is found that recruitment rate, but not mortality, was density dependent, suggesting that the population density was not very high relative to resource levels, and an age-structured matrix model is used to show how knowledge of intrinsic and extrinsic factors affecting vital rates may help managerial decisions by providing explicit links between given environmental conditions and the population growth rates.

Diet Composition of Western Derby eland (Taurotragus Derbianus Derbianus) in the Dry Season in a Natural and a Managed Habitat in Senegal using Faecal Analyses
TLDR
The results indicate that in the dry season the western Derby eland behaves as a pure browser, consuming grasses in negligible amounts, and woody savanna habitat is necessary for future conservation enclosures to ensure adequate natural forage resources for animals and thus to avoid food supplementing that presents a risk of dietary shifts in animals in captivity.

Population Viability Analysis and Genetic Diversity of the Endangered Red Deer Cervus elaphus Population from Mesola, Italy
TLDR
A sensitivity analysis revealed that inbreeding depression and possible catastrophes had a huge impact on the population's prospects, however, the establishment of two subpopulations and successful attempts at reducing the consequences of catastrophic events were able to significantly mitigate the harmful effects of both inbreeding and environmental stochasticity. Expand
GENETIC STATUS AND MANAGEMENT OF CALIFORNIA CONDORS
TLDR
This population bottleneck led to the loss of genetic variation and changes in allele frequencies, including a probable increase in the frequency of the putative allele for chondrodystrophy, a lethal form of dwarfism. Expand
Translocating lions into an inbred lion population in the Hluhluwe‐iMfolozi Park, South Africa
TLDR
It is possible to infuse new genes rapidly and successfully into a small, isolated lion population and such translocations may become an important adaptive management tool as lion populations become increasingly fragmented. Expand
Demographic characterization, inbreeding and maintenance of genetic diversity in the endangered Catalonian donkey breed
TLDR
The correct mating policy between a stallion and a jenny would be that which would maximize the so-called genetic conservation index and minimize the inbreeding coefficient of the hypothetical offspring of the couple. Expand
Quantifying and managing the loss of genetic variation in a free-ranging population of takahe through the use of pedigrees
TLDR
The results demonstrate the value of maintaining pedigrees for wild populations, especially in the years immediately after a translocation event, and suggest that 90% genetic diversity could be maintained over the next 100 years. Expand
Reproduction in a semi-captive herd of pampas deer Ozotoceros bezoarticus
TLDR
Information on reproductive traits of semi-captive breeding of the pampas deer Ozotoceros bezoarticus arerunguaensis, an endangered species, was registered during 20 years, and individual variability in interbirth intervals was significantly higher in primiparous than in multiparous females. Expand
Limitations of Captive Breeding in Endangered Species Recovery
TLDR
Captive breeding should be viewed as a last resort in species recovery and not a prophylactic or long-term solution because of the inexorable genetic and phenotypic changes that occur in captive environments. Expand
Effects of a recent founding event and intrinsic population dynamics on genetic diversity in an ungulate population
TLDR
Monitoring of reproductive success, and incorporation of selective breeding strategies will be required to reduce the rate at which genetic diversity is lost from this small, isolated population of wood bison. Expand
