Studies on wild Eurasian lynx (Lynx lynx) have revealed variation in reproduction between areas, years and individuals. In order to explore potential causes for this variation other than food supply, we analysed data from captive lynx, which provide conditions with minimal environmental variation as all were fed ad libitum. Data from 37 individual female lynx were available from 20 zoos in Norway, Sweden, Finland, Switzerland and the Czech Republic. Data on 177 reproductive events (where a male… 

Patterns of variation in reproductive parameters in Eurasian lynx (Lynx lynx)

The lack of differences in litter sizes among age classes is at odds with most findings in large mammals, and it is argued that this is because the level of prenatal investment is relatively low in felids compared to their substantial levels of postnatal care.

Reproductive maturation in the male Eurasian lynx (Lynx lynx): a study on 55 reproductive organs collected from carcasses during 2002-2005.

The results indicate that most males are fertile during the reproductive season of their second year, and adherence of the prepuce to the penis and absence of penile spines were associated with immaturity.

Reproduction management in female Lynx (Lynx lynx)

It is verified that CLs persist after pregnancy and pseudopregnancy for at least a two-year period, and the described non-felid like ovarian physiology appears to be a remarkably non-plastic system.

Parturition dates in wild Eurasian lynx: evidence of a second oestrus?

This work reports 175 parturition dates from wild Eurasian lynx in Scandinavia and proposes that these represent evidence of a second oestrus which is highly unusual in lynx because of their unique reproductive physiology.

Testosterone production and spermatogenesis in free-ranging Eurasian lynx (Lynx lynx) throughout the year

It is demonstrated that it is possible to analyze the gonadal activity of frozen testis/epididymis tissue postmortem and that male Eurasian lynxes show—opposite to the females—only moderate seasonal changes in their reproductive capacity.

Morphometric characteristics of free-ranging Eurasian lynx Lynx lynx in Switzerland and their suitability for age estimation

Knowledge of the age of individual animals is crucial to assess population dynamics, disease epidemiology and to successfully implement conservation strategies. Morphometric data reflect complex

The cost of maturing early in a solitary carnivore

Analysis of the reproductive tracts of harvested Eurasian lynx females in Norway finds that females that mature early are generally heavier than those that postpone maturation, and suggests that such costs of maturing early in terms of body weight development might be high in terrestrial large carnivores due to a prolonged period of postnatal care.

Reproductive parameters of female South China Tigers in captivity

We monitored the reproductive parameters of South China Tigers (SCT) in captivity from 1983 to 2018. Tigers gave birth in all but 3 months of the year, with a peak in May, June, and July (goodness of



Status and conservation of the Eurasian lynx (Lynx lynx) in Europe in 2001

The Action Plan for the Conservation of the Eurasian Lynx in Europe (Breitenmoser et al. 2000) was based on data up to 1995. This new report presents data up to 2001 (with some more recent

Reproductive status of endemic felid species in Latin American zoos and implications for ex situ conservation

Breeding success and reproductive traits for many endemic felids in Latin American zoos appear to be suboptimal, and likely would benefit from improvements in diet and exhibitry.

Reproductive and genetic consequences of founding isolated lion populations

In an examination of three distinct lion populations, a direct correlation was observed between genetic variability and two physiological traits, incidence of abnormal sperm and circulating testosterone, a critical hormone for spermatogenesis.

Phenotypic quality and senescence affect different components of reproductive output in roe deer

For species such as roe deer, where females rely on food intake rather than fat reserves for reproduction, a two-step process shapes patterns of reproductive output: body mass first sets an upper limit to potential litter size at conception, then reproductive output is limited mainly by senescence and climatic severity through implantation failure.

Ecological Correlates of Life Span in Populations of Large Herbivorous Mammals

The objective of this chapter is to present a comprehensive picture of levels and trends of variation in mammalian life span at both intra- andinterspecific levels.

Captive breeding of cheetahs in North American zoos: 1987-1991

From 1987 to 1991, the North American captive cheetah population increased by 38% (to 266 animals), due to importation and captive breeding, and management recommendations implemented to increase fecundity and population size appear to be successful.

Influence of food availability and reproductive status on the diet and body condition of the European lynx in Finland

The carcasses of the 497 European lynx Lynx lynx (Linnaeus, 1758) killed in two areas in Finland in the 1980s were sexed, the nutritional status and diet of the lynx determined and the breeding stage

Snow conditions may create an invisible barrier for lynx.

It is shown that various features of the snow may influence lynx interaction with its main prey species, the snowshoe hare, and exemplifies how large-scale climatic fluctuations can mechanistically influence population biological patterns.


If canalization occurs, within a given population the variance of canalized fitness components should be less than that of noncanalized components, and among populations an inverse relationship should occur between the potential demographic impact of fitness components and their temporal variability.
