A common assumption is that breeding in polygnous systems is not limited by the number of males because one male can inseminate many females. But here we show that reproductive collapse in the critically endangered saiga antelope (Saiga tatarica tatarica) is likely to have been caused by a catastrophic drop in the number of adult males in this harem-breeding ungulate, probably due to selective poaching for their horns. Fecundity and calf survival are known to be affected by markedly skewed sex… Expand
Harvesting of males delays female breeding in a socially monogamous mammal; the beaver
A negative impact of harvesting of adult males on the timing of parturition in female beavers is found, which can apparently affect their normal reproductive cycle. Expand
Sustainable trophy hunting of African lions
A simple non-invasive technique for estimating lion age in populations lacking long-term records is presented, and it is suggested that quotas would be unnecessary in any male-only trophy species where age determination could be reliably implemented. Expand
Monitoring population productivity in the saiga antelope
The recent poaching-driven collapse in saiga numbers has potentially resulted in reductions in fecundity, which will have an impact on population growth rate, and the potential for monitoring of twinning rate using non-invasive calving aggregation transects is highlighted. Expand
Demographic consequences of adult sex ratio in a reintroduced hihi population.
Using a 12-year longitudinal data set of a free-living and endangered New Zealand passerine, the hihi, it is shown that a changing adult sex ratio has little or no effect on adult female survival or the number of fledglings produced per female. Expand
Turtle mating patterns buffer against disruptive effects of climate change
It is suggested that male mating patterns have the potential to buffer the disruptive effects of climate change on marine turtle populations, many of which are already seriously threatened. Expand
Population Dynamics of a Key Steppe Species in a Changing World: The Critically Endangered Saiga Antelope
Comparison of field observations with data on fluctuations in average annual temperature and rainfall showed that there was no direct effect of climatic factors on the state of this population of saiga antelope. Expand
Ageing and reproductive effort in male moose under variable levels of intrasexual competition
Test hypotheses regarding the pattern of reproductive effort (weight loss during rut) in this capital breeder and how this may be affected by factors such as age, population sex ratio and density provided the first evidence consistent with the terminal investment hypothesis in male mammals. Expand
The ‘big spenders’ of the steppe: sex-specific maternal allocation and twinning in the saiga antelope
It is concluded that an explicit focus on potential constraints can enhance the progress in the field of sex-specific maternal allocation in polytocous species. Expand
Male age structure influences females’ mass change during rut in a polygynous ungulate: the reindeer (Rangifer tarandus)
It is concluded that the male age structure during rut will influence the females’ behavior and mass change and may have implications for Females’ life history and for population dynamics. Expand
Wild boar (Sus scrofa) harvesting using the espera hunting method: side effects and management implications
It is found that the espera hunting method allows very selective harvesting regimes, and thus, it seems a highly effective population management tool. Expand


Dramatic declines in saiga antelope populations
Abstract We present new data on the size of all the saiga antelope populations; three populations of the subspecies Saiga tatarica tatarica in Kazakhstan, one of S. t. tatarica in Kalmykia, Russia,Expand
The ecology and management of the Saiga antelope in Kazakhstan
The ecology and management of the Saiga antelope Saiga tatarica tatarica, a nomadic herding species of the desert, semi-desert and steppe ecosystems of Central Asia, are reviewed. The range area andExpand
The role of males in the dynamics of ungulate populations
It is demonstrated that if the dynamics of a population can be described with a first-order auto-regressive process in a log-linear framework, the asymmetry between the effects of females on the male dynamics and vice versa can introduce a second order process. Expand
The relative roles of density and climatic variation on population dynamics and fecundity rates in three contrasting ungulate species
Using a process–orientated generalized linear modelling approach, it is shown that variations in fecundity rates in populations of three species of ungulates with contrasting life histories are associated with density and winter weather in a remarkably similar manner. Expand
Pastoralism and land degradation in Kazakhstan.
This thesis looks at the major factors, both environmental and institutional, which haye affected pastoralism in Kazakhstan throughout this century, concentrating in particular on the changes whichExpand
