Beyond Body Mass, Beyond Adulthood: The Ontogeny of Sexual Size Monomorphism

American Journal of Biological Anthropology, Volume 190, Issue 1, May 2026.
ABSTRACT Objectives Contest competition for mates and female reproductive energetics influence body size and sexual dimorphism across many primates; nevertheless, some monomorphic species defy these patterns. These deviations may reflect biological anthropology's focus on body mass and adult size as defining features of sexual dimorphism.

Bottlenose dolphin habitat and management factors related to activity and distance traveled in zoos and aquariums.

PLoS ONE, 2021
High-resolution non-invasive cetacean tagging systems can be used to investigate the influence of habitat characteristics and management factors on behavior by quantifying activity levels and distance traveled by bottlenose dolphins (Tursiops truncatus ...

Historical Range Contraction and Extent of Harbour Porpoises (Phocoena phocoena) in the Baltic Sea Revealed by Archival Newspapers

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Archival Swedish newspapers from the 18th to 20th centuries reveal that the Baltic harbour porpoise once utilized the waters along the full Swedish coast, reaching far north into the Gulf of Bothnia, areas where it no longer occurs today. These records show a major range loss and highlight the importance of historical baselines for conservation ...

Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...

From transporter to motor: Evolutionary and structural insights into the emergence of prestin's area‐motor activity in mammals

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Prestin, a member of the SLC26A family, is essential for the electromotility of mammalian outer hair cells, converting voltage changes into mechanical work. In contrast, nonmammalian orthologues function as anion transporters. To investigate the molecular and structural basis of this functional divergence, we performed ancestral sequence ...

Ecoacoustics for context‐rich direct and indirect trophic interaction data and ecological network construction

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1489-1505, May 2026.
Abstract Understanding species interactions is critical for ecology and conservation, yet conventional network construction methods often lack spatiotemporal resolution and important contextual information. The growing field of ecoacoustics enables remote sensing across large spatiotemporal scales and the monitoring of otherwise cryptic communities ...

The distribution of a rarely encountered stingray, Megatrygon microps, informed by citizen science: A systematic review

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
This study combines literature and online data sources to expand the smalleye stingray's range, highlight ecological interactions and specific threats. Abstract Many chondrichthyan fishes are experiencing alarming population declines primarily due to overfishing, exacerbated by their inherently vulnerable life history traits including slow growth rates

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

The impact of urbanisation on social behaviour: a comprehensive review

Biological Reviews, Volume 101, Issue 2, Page 1003-1035, April 2026.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social
