Estimating Narwhal (Monodon monoceros) Age Using Epigenetic Analysis of Skin
Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Age is an important parameter to understand species life‐history characteristics. Recently, DNA methylation methods have emerged as innovative tools to estimate the age of marine mammals. Narwhal (Monodon monoceros) epigenetic age estimates were computed using beluga (Delphinapterus leucas), killer whale (Orcinus orca), bowhead (Balaena ...

Acoustic behavior of melon-headed whales varies on a diel cycle. [PDF]
, 2015 Many terrestrial and marine species have a diel activity pattern, and their acoustic signaling follows their current behavioral state. Whistles and echolocation clicks on long-term recordings produced by melon-headed whales (Peponocephala electra) at ...

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Telomeres, repetitive nucleotide sequences at chromosome ends, shorten with oxidative damage and cell replication, and are increasingly used as biomarkers of stress and physiological state. Despite this potential, telomere length (TL) in marine mammals has been measured using Southern blot hybridization in only a few cases, often from ...

Effects of an extreme temperature event on the behavior and age structure of an estuarine top predator, Carcharhinus leucas [PDF]
, 2012 The frequency of extreme environmental events is predicted to increase in the future. Understanding the short- and long-term impacts of these extreme events on large-bodied predators will provide insight into the spatial and temporal scales at which ...

Exploring Marine Mammal Cognition as a Conservation Tool
Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.

Beluga, Delphinapterus leucas, Group Sizes in Cook Inlet, Alaska, Based on Observer Counts and Aerial Video [PDF]
, 2000 Belugas, Delphinapterus leucas, groups were videotaped concurrent to observer counts during annual NMFS aerial surveys of Cook Inlet, Alaska, from 1994 to 2000. The videotapes provided permanent records of whale groups that could be examined and compared

Predicting Atlantic Bonefish (Albula vulpes) Fork Length From Head Morphometry
Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.This study developed predictive models using generalized linear statistical analyses to estimate Atlantic bonefish (Albula vulpes) fork length (FL) dependent on four head morphometry covariates: snout length, eye diameter, postorbital head length, and head length.

Ecology and Evolution, Volume 15, Issue 12, December 2025.Consistent individual variation in fine‐scale movement traits is unrelated to movements occurring at larger spatio‐temporal scales in undulate skates (Raja undulata). ABSTRACT Individual variation in behavior is widespread in animals. Movement traits, which describe how individuals interact with their environment, can vary across a range of spatial and
