Killer whales : the natural history and genealogy of Orinus orca in British Columbia and Washington by John K. B Ford( Book )

23 editions published between 1994 and 2009 in English and held by 1,265 WorldCat member libraries worldwide

"This book presents updated results of over twenty-five years of killer whale research in British Columbia and Washington. Intended for both whale enthusiasts and researchers, it contains the latest information on killer whale natural history and presents a catalogue of close to 300 photographs of "resident" killer whales as well as a genealogical registry that enables readers to identify individual killer whales and their family groups. The technique of photographing the dorsal fin and grey saddle patch of whales has revolutionized the study of killer whales, allowing researchers to follow individuals over the course of many years."--Jacket
Transients : mammal-hunting killer whales of British Columbia, Washington, and southeastern Alaska by John K. B Ford( )

11 editions published between 1998 and 1999 in English and held by 792 WorldCat member libraries worldwide

Killer whales are found in all oceans of the world, but nowhere are they better known than in the coastal waters of Washington, British Columbia, and Southeastern Alaska, where 25 years of study have yielded many surprising discoveries about their natural history. One of the most remarkable is that two genetically distinct forms of killer whales reside in these waters. The two groups of whales do not associate and each leads a completely different lifestyle. Residents specialize in a diet of salmon and other fish, while transients are hunters of seals, sea lions, porpoises, and even large whales. Enigmatic and elusive, these mammal-hunting whales travel in small groups, often moving unpredictably

Northern resident killer whales of British Columbia : photo-identification catalogue and population status to 2010 by Graeme M Ellis( )

2 editions published in 2011 in English and held by 52 WorldCat member libraries worldwide

Field studies of the life history and ecology of killer whale populations off Canada's Pacific coast have been conducted annually since 1973. These studies are based on the identification of individual whales from photographs of permanent, natural markings. In this report, we summarize abundance trends in the northern resident killer whale population between 1974 and 2010, and provide an updated photo-identification catalogue of individuals in this population, displayed in a matrilineal framework. At the conclusion of the 2010 field season, the population was composed of the 3 clans, 16 pods, and 35 matrilines, with 261 individuals alive (plus four missing and possibly dead). The population is currently more than twice its size in 1974, representing an average annual increase of 2.1%. Continued population monitoring by photo-identification is a key research activity in the recovery strategy for this Threatened population
Population structure and genetic variability in northeastern Pacific killer whales : towards an assessment of population viability by L. G Barrett-Lennard( )

4 editions published in 2001 in English and held by 43 WorldCat member libraries worldwide

Les études menées à long terme sur l'orque dans les eaux côtières de la Colombie-Britannique ont permis d'identifier deux populations sympathiques et distinctes: des résidents piscivores et des migrateurs dont le régime alimentaire est composé d'autres mammifères. Un troisième groupe, les hauturiers, fréquente la marge externe de la plate-forme continentale. La population résidente de la C.B. englobe deux sous-populations de la C.B., considérées comme menacées à l'heure actuelle par le comité sur le statut des espèces menacées de disparition au Canada. Une autre sous-population de résidents, dont le statut n'est pas officiel, et deux sous-populations de migrateurs ont aussi été signalées en Alaska. Ce complexe de populations et de sous-populations qui perdure malgré l'absence d'obstacles évidents à la dispersion pose un problème aux responsables de la conservation, qui doivent décider si les sous-populations doivent être évaluées ensemble ou séparément. Il est évident que les décisions devraient reposer sur une connaissance du caractère distinctif des sous-populations. Le présent rapport fait état d'une analyse moléculaire conçue en vue d'acquérir cette connaissance. Elle a permis a) d'établir les caractéristiques génétiques de chaque sous-population d'orque, b) de comparer la variabilité génétique entre les sous-populations et c) d'analyser les patrons d'accouplement au sein des sous-populations résidentes en vue d'établir les niveaux de consanguinité
Northern resident killer whales of British Columbia : photo-identification catalogue and population status to 2010 by Graeme M Ellis( Book )

2 editions published in 2011 in English and held by 39 WorldCat member libraries worldwide

In this report, the authors present a summary of the current population status of the northern resident killer whale population through 2010, and an updated photo-identification catalogue of individuals. This catalogue includes demographic and genealogical data for all members of the northern resident population, gathered from annual photo-identification population censuses and associated long-term visual monitoring respectively. It is intended to provide research colleagues, monitoring program personnel as well as professional and recreational marine wildlife viewers with a tool to facilitate their studies and enrich their observations.--Document

An assessment of the potential for recovery of west coast transient killer whales using coastal waters of British Columbia = Évaluation du potentiel de rétablissement de l'épaulard migrateur du Pacifique nord-est vivant dans les eaux côtières de la Colombie-Britannique by John K. B Ford( Book )

3 editions published in 2008 in English and held by 8 WorldCat member libraries worldwide

Mammal-eating transient killer whales off Canada's Pacific coast are listed as threatened under the Species-at-Risk Act. This document presents a recovery potential assessment for west coast transient (WCT) killer whales to provide a basis for on-going recovery planning for this population. For this assessment, an archive of photo-identifications of individual WCT whales collected during 1479 sightings between 1974 and 2006 was used. A capture-recapture approach was applied to the analysis of this dataset and Bayesian statistical techniques were employed to estimate population abundance and dynamics.--Includes text from document

Linking prey and population dynamics : did food limitation cause recent declines of 'resident' killer whales (Orcinus orca) in British Columbia by John K. B Ford( Book )

2 editions published in 2005 in English and held by 5 WorldCat member libraries worldwide

Two populations of fish-eating killer whales in British Columbia, known as residents, are listed under the Species at Risk Act due to their small population size and recent unexplained declines in abundance. Recent studies have shown that chinook & chum salmon are important prey for this species. This report assesses whether food limitation was potentially a significant factor in recent declines of these whale populations. The report examines the relationship between trends in killer whale population dynamics based on long-term photo identification data, and abundance levels of chinook & chum salmon off the British Columbia coast over the past 25 years. Other factors that may be involved in the decline of this species are also discussed
Prey selection and food sharing by fish-eating 'resident' killer whales (Orcinus orca) in British Columbia = Sélection des proies et partage de la nourriture par les épaulards (Orcinus orca) 'résidants' piscivores, en Colombie-Britannique by John K. B Ford( Book )

2 editions published in 2005 in English and held by 4 WorldCat member libraries worldwide

This report describes field studies of foraging behaviour & feeding by the resident population of killer whales in the coastal waters of British Columbia, 1973-2004. The studies were conducted primarily to address gaps in knowledge of the whale diet. In particular, field efforts in 2003-04 were focussed on documenting the detailed aspects of prey capture & handling in order to assess the validity of using prey fragment sampling to interpret dietary preferences. The results present new information on the occurrence of co-operative foraging and prey sharing in resident killer whales and the implications of this behaviour with respect to the use of prey fragments as indicators of diet are discussed. Extensive sampling of feeding events also allowed quantitative evaluation of prey selection in relation to prey species availability, as well as prey selection by age & sex class and group membership of feeding whales
