Integrated fisheries stock assessment models (SAMs) and integrated population (IPMs) are used in biological ecological systems to estimate abundance demographic rates. The approaches fundamentally very similar, but historically have been considered as separate endeavors, resulting a loss of shared vision, practice progress. We review the two identify similarities differences, with view identifying key lessons that would benefit more generally overarching topic ecology. present case study for...
Abstract Environmental DNA (eDNA) analysis is a technique for detecting organisms based on genetic material in environments such as air, water, or soil. Observed eDNA concentrations vary space and time due to biological environmental processes. Here, we investigate variability production loss by sampling water adjacent managed population of non‐native cetaceans near‐hourly timescale 48 hr. We used diverse approaches modeling methods describe observed then compare the magnitude mechanisms....
Effective conservation and management of animal populations requires knowledge abundance trends. For many species, these quantities are estimated using systematic visual surveys. Additional individual-level data available for some species. Integrated population modeling (IPM) offers a mechanism leveraging sets into single estimation framework. IPMs that incorporate both population- have previously been developed birds, but rarely applied to cetaceans. Here, we explore how can be used improve...
Anthropogenic activities can lead to changes in animal behavior. Predicting population consequences of these behavioral requires integrating short-term individual responses into models that forecast dynamics across multiple generations. This is especially challenging for long-lived animals, because the different time scales involved. Beaked whales are a group deep-diving odontocete respond behaviorally when exposed military mid-frequency active sonar (MFAS), but effect nonlethal on beaked...
Abstract Knowledge about the demographic and environmental factors underlying population dynamics is fundamental to designing effective conservation measures recover depleted wildlife populations. However, sparse monitoring data or persistent knowledge gaps threats make it difficult identify drivers of dynamics. In situations where small, declining, populations show continued evidence decline for unknown reasons, integrated models can efficient use available improve our understanding...
Passive acoustic monitoring is a promising approach for long-term trends in harbor porpoise (Phocoena phocoena) abundance. Before passive can be implemented to estimate abundance, information about the detectability of needed convert recorded numbers echolocation clicks densities. In present study, paired data from grid nine click detectors (C-PODs, Chelonia Ltd., United Kingdom) and three days simultaneous aerial line-transect visual surveys were collected over 370 km2 study area. The focus...
Abstract Behavioral responses of beaked whales (family Ziphiidae) to naval use mid‐frequency active sonar (MFAS) have been quantified for some species and regions. We describe the effects MFAS on probability detecting diving groups Blainville's U.S. Navy Pacific Missile Range Facility (PMRF) in Hawaii compare our results previously published same at Atlantic Undersea Test Evaluation Center (AUTEC) Bahamas. passive acoustic data collected bottom‐mounted hydrophones before during six training...
