Evidence-based marine protected area planning for a highly mobile endangered marine vertebrate (2013, background): “, 2003), our study further highlighted the complex issues associated with meeting the requirements of one species (Babcock et al., 2005; Hooker et al., 2011; Taylor et al., 2007).”
Social and Behavioural Factors in Cetacean Responses to Overexploitation: Are Odontocetes Less “Resilient” Than Mysticetes? (2012, methodology): “Some of the difference is likely due to the relative lack of good monitoring data for odontocetes [19].”
Accelerating population decline of Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) (2012, background): “…or declines, usually requires decades of field investigations, and the target population may have declined substantially before a change in abundance is detectable (Gerrodette, 1987; Taylor and Gerrodette, 1993; Thompson et al., 2000; Taylor et al., 2007; Wilson et al., 2011; Huang et al., 2012a).”
The global extent and character of marine mammal consumption by humans: 1970-2009 (2011, background): “Even in affluent countries with resources dedicated to the conservation of marine mammals, population status and trends are difficult to assess (Taylor et al., 2007).”
Underestimating the damage: interpreting cetacean carcass recoveries in the context of the Deepwater Horizon/BP incident (2011, background): “…taken from (Waring et al. 2009b), unless otherwise noted. b Population-level estimates are preferable but generally unavailable, so data taken from (Taylor et al. 2007a). c Calculated as the abundance multiplied by mortality rate ( = 1–survival rate). d Population abundance and stranding data…”
Synthesizing multiple data types for biological conservation using integrated population models (2018, background): “These conditions result in limited longitudinal data to model population viability, extrapolate inference at large scales, and detect significant changes in population trends within time frames for appropriate management actions (Taylor et al., 2007; Mosnier et al., 2015).”
Marine seismic surveys and ocean noise: time for coordinated and prudent planning (2015, background): “…populations, numerical abundance and trends in abundance are the standard measurements for assessing population status, but such measurements are difficult to obtain and have limitations (eg require decades of research and are complicated by resolution of temporal trends; see Taylor et al. 2007).”
Marine mammal bycatch in gillnet and other entangling net fisheries, 1990 to 2011 (2013, background): “Such data requirements are rarely met, even in highly developed countries with strong legal and institutional foundations (Taylor et al. 2007).”
A Brief Review of Known Effects of Noise on Marine Mammals (2007, background): “The vast majority (72-90%) of serious population declines in cetaceans would not be detected under the current population monitoring effort ( Taylor, Martinez, Gerrodette, Barlow, & Hrovat, 2007 ).”
Abundance and conservation status of the Yangtze finless porpoise in the Yangtze River, China (2008, background): “The precision of surveys should be maximized because it is extremely difficult to detect trends in abundance, particularly when population size is low (Taylor et al., 2007).”
The impacts of anthropogenic ocean noise on cetaceans and implications for management (2007, background): “Taylor et al. (2007) noted that 72% of large whale declines, 90% of beaked whale declines, and 78% of dolphin or porpoise declines would not be detected under current monitoring effort, even if the declines were so dramatic as to represent a 50% decrease in abundance in 15 years.”
Design and field methods for sighting surveys of cetaceans in coastal and riverine habitats (2008, background): “…and the detected decline led to conservation actions (e.g. Cook Inlet beluga whale; Hobbs, Rugh & DeMaster, 2000), it is important to note that the power to detect trends from repeated abundance surveys, even if they were carefully designed, is likely to be very low (Taylor et al., 2007).”
First evidence that marine protected areas can work for marine mammals (2012, background): “This is especially so as populations become rare (Taylor & Gerrodette 1993), hence the ability to detect population changes from trends in abundance is usually poor (Taylor et al. 2007).”
US Atlantic and Gulf of Mexico marine mammal stock assessments - 2015 (2016, background): “For example, the power to detect a precipitous decline in abundance (i.e., 50% decrease in 15 years) with estimates of low precision (e.g., CV > 0.30) remains below 80% (alpha = 0.30) unless surveys are conducted on an annual basis (Taylor et al. 2007).”
