  journal={Population Ecology},
African lions (Panthera leo) live in social groups (prides) that exhibit group territorial behavior. Pride persistence is expected to depend on its ability to compete against neighboring prides as well as on average rates of reproduction and survival, thus providing a meaningful measure of intergenerational reproductive success. We used Akaike’s Information Criterion (AIC) to select the best approximating models explaining how demographic variables influenced pride persistence during a 30-year… 
Effects of Trophy Hunting on Lion and Leopard Populations in Tanzania
Lion population trends in protected areas where lion abundance has been directly measured and data on the frequency of lion attacks on humans in high-conflict agricultural areas are summarized and quantitative analyses suggest that annual hunting quotas should be limited.
Methods for lion monitoring: a comparison from the Selous Game Reserve, Tanzania
The Selous Game Reserve in Tanzania is believed to contain Africa’s largest population of lions (Panthera leo), making it a popular destination for trophy hunters and photographic tourists. However,
The Space Between A geospatial analysis of connectivity between lion populations in East Africa
Lion (Panthera leo) populations and habitat range are in steep decline. Lions are increasingly isolated in protected areas and other pockets of habitat. Habitat fragmentation lowers effective
Examining the Extinction of the Barbary Lion and Its Implications for Felid Conservation
The evidence presented for a much later persistence of lions in North Africa, including generations when sightings were nil, suggests caution when considering felid populations as extinct in the wild, and raises the possibility that captive animals descended from the Moroccan royal collection are closer contemporaries to wild Barbary lions.
Genetic insights into dispersal distance and disperser fitness of African lions (Panthera leo) from the latitudinal extremes of the Kruger National Park, South Africa
Large genetic differences between the two sampling localities, and low relatedness among males and high dispersal rates among females in the south, are suggestive of unstable territory structure and high pride turnover, have potential implications for spread of diseases and the management of the Kruger lion population.
Patterns of bird predation on reptiles in small woodland remnant edges in peri-urban north-western Sydney, Australia
It is found that there was a strong negative correlation between skink numbers and predatory birds (individually and combined) consistent with higher predation pressure in the edge compared to the core of remnants.
Conservation status of the lion (Panthera leo Linnaeus, 1758) in Tanzania . June 2010
The IUCN SSC organized two regional workshops, one for West and Central Africa (2005) and one for Eastern and Southern Africa (2006), to produce regional conservation strategies for the lion.
Protection of the African Lion: A Critical Analysis of the Current International Legal Regime
This article looks at the current international regime that pertains to the African lion, a species that needs adequate protection across its range (a range that does not adhere to state boundaries).
Individual Identification of Large Felids in Field Studies: Common Methods, Challenges, and Implications for Conservation Science
Large felids represent some of the most threatened large mammals on Earth, critical for both tourism economies and ecosystem function. Most populations are in a state of decline, and their monitoring


Reduced dispersal and opportunistic territory acquisition in male lions ( Panthera leo )
Investigation of life-history patterns in lions Panthera leo living in savanna woodlands of the Kruger National Park, South Africa, found that both sexes gain an advantage by not dispersing far, and use currently undocumented mechanisms to avoid inbreeding.
Case Study of a Population Bottleneck: Lions of the Ngorongoro Crater
The simulations suggest that the Crater population may have passed through previous bottlenecks before 1962 but that the level of heterozygosity in the breeding population has been declining since the mid-1970s, regardless of the population's genetic composition in the 1960s.
Top–down population regulation of a top predator: lions in the Ngorongoro Crater

It is reported on 40 years of data on the lion population in Ngorongoro Crater, Tanzania, which showed strong evidence of density–dependent regulation at 100–120 individuals but has remained below 60 individuals for the past decade despite consistently high prey abundance.
Ecological Change, Group Territoriality, and Population Dynamics in Serengeti Lions
It is found that group living in African lions causes a complex response to long-term ecological change, and the observed pattern of “saltatory equilibria” results from the lions' grouping behavior.
The Evolution of Sex-Biased Dispersal in Lions
Most female lions remain in their natal pride for their entire lives, but about a third emigrate before they reach four yrs of age. Most emigrating females leave either when they are evicted by an
Factors affecting the hunting success of male and female lions in the Kruger National Park
It is concluded that in African ecosystems, the hunting success of male and female lions varies with a range of combinations of lion-, prey- and environment-related variables, and the hunting ability of male lions is demonstrated, which has perhaps been understated in other studies.
Ritual vs. retaliatory killing of African lions in the Ngorongoro Conservation Area, Tanzania
The Ngorongoro Conservation Area (NCA), Tanzania, is a multiple land-use area where Maasai pastoralists co-exist with large migratory herbivores and associated carnivores. Maasai retal- iate against
Empirical support for a despotic distribution in a California spotted owl population
Spotted owls in this study tended to occupy territories with the highest λ-sub-pf, supporting the assumption of ideal perceptual abilities within this population and suggesting that some individuals do not assess site quality accurately because of perceptual limitations, prey dynamics, and large territory sizes.
