Download or read book Behavioral Physical and Acoustic Characteristics of Humpback Whales Megaptera Novaeangliae at Argus Island written by Coleman Levenson and published by . This book was released on 1969 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the behavioral, physical, and acoustic characteristics of humpback whales was conducted at Argus Island Tower near Bermuda during April 1968. Swimming and diving habits were observed and photographed, and underwater sounds produced by the whales were recorded. Whale behavior at the surface prior to diving varied according to the time span of the succeeding dives. Information concerning the range of variation in physical appearance was sufficient to improve the quality of current visual identification aids. Preliminary analysis of humpback sounds indicates components at frequencies as high as 8kHz. (Author).

Download or read book Intra annual Changes in Population Parameters as Indicators of Humpback Whale Megaptera Novaeangliae Migratory Behavior written by Casey Clark and published by . This book was released on 2013 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many techniques used to study animal migrations rely on observations of specific animals, which provide valuable information about individuals studied but do not capture population variability. By examining changes in population parameters, researchers may gain a better understanding of migratory behaviors. In this study, intra-annual changes in population parameters were used to study migratory behaviors of humpback whales off central California in 2011/2012. Data were compared with a historic dataset from 2004/2005. Parameters measured included sex ratio, pregnancy rate, mitochondrial DNA haplotype frequencies and mean [delta]13C and [delta]15N values. Weighted moving averages of the sex ratio were moderately effective at revealing deviations from expected values. Progesterone assays successfully determined pregnancy in humpbacks and revealed a previously undocumented intra-annual decrease in pregnancy rate in 2011. Analyses of mitochondrial DNA haplotype frequencies indicated greater prevalence of haplotypes associated with British Columbia and Washington late in the year; however, the origin of these animals was unclear. Stable isotope ratios proved ineffective for measuring a fasting effect in humpbacks early in the year. The effectiveness of these parameters for investigating migratory behaviors varied, but used in conjunction with traditional methods of study, they may help create a broader understanding of animal migrations.

Download or read book Satellite Telemetry and Humpback Whales written by Amy Kennedy and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation has been prepared in manuscript format and contains four individual papers. Each paper/chapter is formatted for the journal to which it has been, or will be, submitted. In the first manuscript, “From Whaling to Tagging: The evolution of knowledge regarding humpback whales in their North Atlantic breeding grounds”, I describe the evolution of humpback whale research from the days of Yankee whaling to the most recent satellite telemetry project in the West Indies breeding grounds. The humpback whales that over-winter in the West Indies are part of one of the most heavily studied whale populations in the world; projects conducted in this area have served as models for humpback whale research world-wide. This manuscript will be submitted for publication in Mammal Review in 2014. In my second manuscript, “Local and migratory movements of humpback whales satellite tracked in the North Atlantic Ocean”, I report the results of a satellite telemetry project that was conducted in the winters of 2008 through 2012 in the breeding areas of Silver Bank (Dominican Republic) and Guadeloupe (French West Indies). The results from this project add a level of detail to the current knowledge about North Atlantic humpback whale habitat use, migration, and population structure that could not be obtained without current satellite tagging technology. This paper has been reviewed and accepted for publication by the Canadian Journal of Zoology and will be published by November, 2013 ii In my third manuscript, “Individual variation in movements of humpback whales satellite tracked in the eastern Aleutian Islands and Bering Sea”, I report the results from a satellite telemetry project conducted off Dutch Harbor, (Alaska, USA) in the summers of 2007 through 2011. Satellite telemetry from this project showed the fine-scale use of foraging habitat in a North Pacific feeding ground. Additionally, a long-distance, within-season travel event was recorded in 2010, prompting speculation about the humpback population structure throughout the Bering Sea. This manuscript has been reviewed and accepted for publication by Endangered Species Research and will be published by November, 2013. In the fourth manuscript, “Assessing implantable satellite tag extrusion using light sensors”, I report the results of a novel approach for remotely quantifying tag rejection; the use of tag-mounted light sensors to indicate extrusion rate. The data for this paper were collected during a 2011 follow-up study aimed at assessing the behavioral and physiological responses of Gulf of Maine humpback whales to current tagging methods. Tag diagnostic technology like this, while still being developed, could significantly improve future telemetry work by updating tag design and placement methods to increase overall project efficiency. This paper has been accepted as a poster presentation at the 20th Biennial Conference on the Biology of Marine Mammals (December 2013, Dunedin New Zealand). It will be updated with the results from the 2013 Gulf of Maine tagging field season and submitted to a peer reviewed journal in 2014.

Download or read book Using New Tag Attachments to Study Humpback Whale Fine scale Spatiotemporal Dive Behavior Habitat Use and Reaction to Ships Off Northern California written by Angela Renee Szesciorka and published by . This book was released on 2015 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the foraging behavior of humpback whales (Megaptera novaeangliae) is important for ethology and monitoring ecosystem-level health. Because humpback whales are generalist foragers, regional dive differences should reveal information about prey preference and availability. Any external influences of foraging behavior has important conservation implications because disruptions to foraging may impact individual fitness. From 2013 to 2014, I opportunistically tagged 22 humpback whales and 12 blue whales (Balaenoptera musculus) to test eight tag attachments, which were used to study the fine-scale dive behavior of humpback whales in four regions off California, and when they encountered ships. Four-barb tag configurations remained on the longest with no difference in reaction and no infection; however, some breakage occurred. Whales in Bodega Canyon and on the continental break/slope made deeper, longer foraging dives to feed on krill, while whales in Monterey Bay and on the continental shelf foraged in shallow waters on more fish species. Encounters between ships and whales showed changes to overall dive behavior depending on dive type, but responses varied. Whales, mostly juveniles and injured whales, were more at risk in the upper 50 m of the water column during the daytime. This study provided insight into how humpback whale dive behavior differenced among regions and how ship encounters affected dive behavior.
