Head-start Juvenile and Adult Resident Eastern Box Turtles (Terrapene carolina carolina): Winter Ecology Including Microhabitat Selection, Temperature Tolerance and Philopatry
… tolerance, microhabitat and degree of philopatry to hibernacula for juvenile and adult E. box turtles for two consecutive winters in Charles City Co, VA. The turtles were tracked via radio telemetry to record point locations during the active and inactive seasons. iButton data loggers …

Genetic Dispersal Patterns in Cetaceans: The Development of Dolphin, Whale, and Porpoise Subpopulations
… dispersal patterns such as sex-biased dispersal, philopatry, and subpopulations. The papers were examined for theories behind dispersal patterns. It has been found that populations are highly subdivided in small areas, with female philopatry. Even with female philopatry, there was no sex-biased …

Further studies on the breeding biology of redshank (Tringa totanus L.)
… males and were more likely to disperse. Natal philopatry is discussed in relation to pre and postfledging mortality. Philopatry is non sex biased and is estimated at being very high. Chick growth and development is considered and an age determining formula devised for ageing chicks from their …

Population genetics of the Cape serotine bat (Neoromicia capensis) in South Africa
… been documented. Almost nothing is known about philopatry, migration and dispersal patterns of the Cape serotine bat and therefore nothing is known about its population structure. In this study I use microsatellite and mitochondrial D-Ioop sequences to determine the genetic structure of the Cape …

Population Demographics of Cougars in the Black Hills: Survival, Dispersal, Morphometry, Genetic Structure, and Associated Interactions with Density Dependence
… 2) document dispersal movements and assess philopatry of a cougar population semi-isolated from other populations in a mountainous region surrounded by atypical cougar habitat, 3) assess the genetic structure of a semi-isolated cougar population, 4) document morphological attributes of a …

Photo-identification of humpback whales (Megaptera novaeangliae) between Iceland, Norway and Guadeloupe
… feeding grounds through maternally-directed site philopatry and the spatial distribution of prey has helped identify five separate feeding grounds in the North Atlantic: Gulf of Maine, Eastern Canada (Newfoundland / Labrador, Gulf of St. Lawrence), West Greenland, Iceland and Norway. Breeding …

An Examination of Gene Flow Among Distinct Management Units of The Reddish Egret
… populations and management units and greater philopatry by females than by males. Recent banding and telemetry data also support differences in movement patterns between males and females. Lastly, gene flow between the Baja California population and the other populations is weak; whereas, we …

Ecology and Structure of Black Bear (Ursus americanus) Populations in the Interior Highlands of Arkansas
… density estimates. There was evidence for female philopatry in both source and expanding populations, with relatedness declining with distance until about 30 km. In recently expanding populations, male-male dyads followed a similar pattern to female-female dyads with relatedness decreasing with …

The Effects of Food, Cover and Competition on Demography, Dispersal and Density of Voles
… supported the hypothesis that dispersal and philopatry were components of a mixed evolutionary stable strategy.

The population dynamics and conservation of the African Black Oystercatcher, Haematopus moquini
… populations; (c) assess levels of natal site philopatry and adult site fidelity in local populations; (d) assess the long-term population viability of the species; and (e) assess the potential importance of territorial behaviour in governing the population dynamics of local oystercatcher …

Investigation of population abundance, distribution, and population linkage of Indo-Pacific Bottlenose Dolphins (Tursiops aduncus) on the north and south of Zanzibar using mark-recapture and acoustic methods
… genetic studies, this study suggests female philopatry and male mediated gene flow between the two areas; however, more genetic markers are necessary to test this interpretation. Further work is also necessary to quantify the degree of movement of dolphins around Zanzibar Island, and …

Cheetah of the Serengeti Plains: A home range analysis
… females age. I provide quantitative evidence for philopatry in female- and juvenile dispersal in male cheetah of the Serengeti Plains. I use simple overlap metrics to show that overlap in lifetime and core ranges is greater in related than unrelated female pairs. I use multi-response permutation …

Cryptic Herbivorous Invertebrates Restructure the Composition of Degraded Coral Reef Communities in the Florida Keys, Florida, USA
… exhibited a high degree of philopatry on patch reefs, and that crabs >30mm carapace length reach a size refuge from predation and experience lower mortality. Reef fish abundance and species richness were also greater on reefs with high crab density than on controls. …

Phylogeny and phylogeography of four southern ocean petrels
… island colonies and exhibit strong natal philopatry. They may thus be expected to show population divergence, but published studies show that this is not always the case. Most studies to date have concentrated on northern hemisphere species, with mostly albatrosses studied within the …

An intensive study of movement and population dynamics in Triakis megalopterus in the De Hoop Marine Protected Area, South Africa
… at De Hoop MPA displays a high level of philopatry. Individuals show consistent small movements over periods up to thirteen years. Multiple recaptures of the same sharks indicate frequent and repeated use of home ranges in the order of 1.0 km of coastline. The best fit model suggests a …

Stress and sociality in a patrilocal primate: Do female spider monkeys tend-and-befriend?
… that this strategy is unrelated to female philopatry. Since our hominid ancestors are presumed to be male-philopatric, examining if this strategy applies to unrelated females is essential to understanding the evolutionary context of this mechanism. Here, I examine the tend-and-befriend …

Cranes and crops: investigating the viability of blue cranes in agricultural lands of the Western Cape
