Predicting spatiotemporal persistence of rare species: An example with North Atlantic right whales

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Knowledge of when species remain in specified areas is essential for survey design, conservation, and management. Using species occurrence data to predict persistence in space and time (i.e., presence of one or more individuals of the species of interest within a defined spatial area over a duration of a specified number of days) may be ...

Quantifying Ship Strike Risk to Breeding Whales in a Multiple-Use Marine Park: The Great Barrier Reef

Frontiers in Marine Science, 2020
Spatial risk assessments are an effective management tool used in multiple-use marine parks to balance the needs for conservation of natural properties and to provide for varying socio-economic demands for development. The multiple-use Great Barrier Reef

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles

Engineering Reports, Volume 8, Issue 3, March 2026.
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Communicating amidst the noise: modeling the aggregate influence of ambient and vessel noise on baleen whale communication space in a national marine sanctuary

Endangered Species Research, 2018
Anthropogenic noise negatively impacts many species. One of the more insidious effects of elevated noise levels is the reduction in area over which animals are able to acoustically communicate, often termed communication masking.

Computer Simulation of Musical Evolution: A Lesson from Whales [PDF]

, 2015
Simulating musical creativity using computers needs more than the ability to devise elegant computational implementations of sophisticated algorithms. It requires, firstly, an understanding of what phenomena might be regarded as music; and, secondly, an ...

Passive Acoustic Monitoring Reveals New Insights Into the Acoustic Occurrence and Foraging Activity of Hector's Dolphins in Porpoise Bay, New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
To effectively mitigate disturbances from human activities on vulnerable dolphin populations, it is crucial to understand fine‐scale variation in habitat use. This study investigated the habitat utilisation of a small subpopulation of Hector's dolphins (Cephalorhynchus hectori) in Porpoise Bay, New Zealand.

A Novel Dual‐Clustering Approach for Identifying Hydrological Response Patterns From Catchment Characteristics and Environmental Changes

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Understanding how catchments respond to environmental changes is critical for water resource management. However, few studies have systematically linked catchment characteristics, environmental changes, and hydrological responses. Therefore, this study proposes a novel dual‐clustering approach for identifying hydrological response patterns. It

Bi-class classification of humpback whale sound units against complex background noise with Deep Convolution Neural Network

, 2017
Automatically detecting sound units of humpback whales in complex time-varying background noises is a current challenge for scientists. In this paper, we explore the applicability of Convolution Neural Network (CNN) method for this task.

Severe Hearing Loss in the World's First Successfully Captive‐Born Yangtze Finless Porpoise: Impact of High Underwater Sound Exposure and Congenital Hearing Disorders

Integrative Zoology, Volume 21, Issue 2, Page 331-342, March 2026.
The audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.
