Movements and Habitat Use of Cuvier's and Blainville's Beaked Whales in Hawaii: Results from Satellite Tagging in 2009/2010

Population structure of melon‐headed whales (Peponocephala electra) in the Hawaiian Archipelago: Evidence of multiple populations based on photo identification

“…The photo-identification catalog was compiled following the same protocol used in other Hawaiian odontocete catalogs (e.g., Baird et al 2008aBaird et al , b, 2009McSweeney et al 2009). Photo sorting and matching was performed in ACDSee Pro v. 2.0 and 2.5, without the use of any additional photo matching software.…”

“…We used the Bayesian method described by to determine what rates of dispersal between populations are consistent with our data. Baird et al's (2009) method uses the catalog size and number of individuals identified in each population in each year of the study (Table 1), along with estimates, drawn from prior distributions, of the abundance of each population (N j ) and the dispersal rate (d) between them, to calculate the likelihood of failing to detect any immigrant individuals. The Sample-Importance Resample (SIR) algorithm (Rubin 1988) is then used to estimate the posterior distributions of N j and d. For d, we used a uniform prior between 0% and 1.5% per year.…”

“…2007, 2010; Baird et al . 2008 b , 2010 c ). There are a number of distinct island‐associated populations of common bottlenose dolphins ( Tursiops truncatus ), with limited movement between island regions (Baird et al .…”

“…Studies over the last decade have shown remarkable differences in population structure, habitat use, and movements among species and even between populations of the same species (e.g., Andrews et al 2006Andrews et al , 2010Baird et al 2008aBaird et al , b, 2009Mc-Sweeney et al 2007, 2009. There are at least two genetically distinct populations of false killer whales (Pseudorca crassidens), for example, an insular population, closely associated with the main Hawaiian Islands, and an offshore population (Chivers et al 2007(Chivers et al , 2010Baird et al 2008bBaird et al , 2010c. There are a number of distinct islandassociated populations of common bottlenose dolphins (Tursiops truncatus), with limited movement between island regions , Martien et al 2011.…”

Movements and Spatial Use of False Killer Whales in Hawaii: Satellite Tagging Studies in 2009

“…Baird et al (2010a). The tags used were based on a design of Andrews et al (2008), which have been used on 16 species of cetaceans (e.g., Schorr et al 2009aSchorr et al , 2009bBaird et al 2010bBaird et al , 2011. The tag contained a Wildlife Computers (Redmond, Washington, USA) ARGOS-linked SPOT-5 location-only Platform Transmitter Terminal in the Low Impact Minimally Percutaneous External-electronics (LIMPET) configuration.…”
