Age-Specific Survival and Reproductive Rates of Mediterranean Monk Seals at the Cabo Blanco Peninsula, West Africa

Live encounter data provides the first complete set of survival rate estimates for the Endangered Mediterranean monk seal birth into adulthood, as well as the first age-specific reproductive rates for the species.

Model-Based Localization for Deep-Diving Cetaceans Using Towed Line Array Acoustic Data

A model-based localization approach is applied to account for errors not typically accounted for by the standard method of passive acoustic monitoring when conducting line-transect cetacean abundance surveys.

Patterns of Depredation in the Hawai’i Deep-Set Longline Fishery Informed by Fishery and False Killer Whale Behavior

We analyzed behavior data on false killer whales to identify patterns that could help fishermen avoid interactions with whales.

Acoustic Classification of False Killer Whales in the Hawaiian Islands Based on Comprehensive Vocal Repertoire

This case study illustrates use of a suite of routines designed to efficiently detect cetacean sounds, extract features, and classify the detection to species using ship-based, visually verified detections of false killer whales.

An Acoustic Survey of Beaked Whales and Kogia spp. in the Mariana Archipelago Using Drifting Recorders

We demonstrate a combination of autonomous drifting acoustic recorders, environmental sampling and remote satellite data are powerful tools for studying the habitat dependent distribution of cryptic cetacean species in minimally studied and remote regions

Sea Turtles Across the North Pacific Are Exposed to Perfluoroalkyl Substances

A risk assessment showed concern for immunosuppression in Kailua green turtles and alarming concern for hawksbill developmental toxicity.

Sighting Patterns Reveal Unobserved Pupping Events To Revise Reproductive Rate Estimates for Hawaiian Monk Seals in the Main Hawaiian Islands

We used sighting reports to describe female breeding biology and reproductive success in the main Hawaiian Islands.

Revising Reproductive Rate Estimates for Hawaiian Monk Seals in the Main Hawaiian Islands

By examining sighting histories, we infer that 25 unobserved pupping events that had previously gone uncounted. This is the highest reproductive rate reported for any of the Hawaiian monk seal breeding sites.

Trace Element Concentrations in Blood and Scute Tissues From Wild and Captive Hawaiian Green Sea Turtles (Chelonia mydas)

The present study compares trace element concentrations in green turtles in captivity at Sea Life Park Hawaii to wild green turtles in Kapoho Bay, Hawaii, USA.

Ensemble Random Forests as a Tool for Modeling Rare Occurrences

Through simulation, we show that ERFs outperform Random Forest with and without down-sampling, as well as with the synthetic minority over-sampling technique, for highly class imbalanced to balanced datasets.
