Comparative Aquatic Toxicology of Pesticides and Plastics Using the Model Estuarine Fish, Inland Silverside

Creator:: Hutton, Sara J.
Abstract:: Based on current trends both pesticide and plastic production are expected to continue to rise in the coming decade. A growing global population coupled with the effects of climate change are the main drivers of increased pesticide use. Throughout this dissertation pesticides refer to herbicides, fungicides, and insecticides. Plastic production...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:: Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.
Abstract:: Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...

Plankton food web dynamics and larval fish success : influence of prey and predator distributions on larval fish diet, growth, and assemblages in the Straits of Florida

Creator:: Gleiber, Miram R.
Abstract:: Survival of marine fishes during their early life history stage is tightly related to prey availability and predation pressure. Yet, our understanding of how individual larvae to entire assemblages are constrained by these factors is limited. We integrated biological sampling of larval fishes with fine-scale in situ imaging to relate...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:: Barlow, Dawn R.
Abstract:: Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...

Classification of Animal Movement Behavior through Residence in Space and Time

Creator:: Orben, Rachael A., Thompson, David R., Tolkova, Irina, and Torres, Leigh G.
Abstract:: Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...

An integrated approach to historical population assessment of the great whales: case of the New Zealand southern right whale

Creator:: Jackson, Jennifer A., Carroll, Emma L., Smith, Tim D., Zerbini, Alexandre N., Patenaude, Nathalie J., and Baker, C. Scott
Abstract:: Accurate estimation of historical abundance provides an essential baseline for judging the recovery of the great whales. This is particularly challenging for whales hunted prior to twentieth century modern whaling, as population-level catch records are often incomplete. Assessments of whale recovery using pre-modern exploitation indices are therefore rare, despite the...
