Density and Abundance of Cetaceans in the Eastern Tropical Pacific Based on a Spatial/Temporal Analysis of 1986–2006 Line‐Transect Surveys

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The abundance of cetaceans in the eastern tropical Pacific Ocean (ETP) is estimated using spatial/temporal density modeling and conventional line‐transect approaches. Line‐transect data are analyzed from 10 ship‐based visual sighting surveys from 1986 to 2006 that include 281,000 km of survey effort in a 19.4 million km2 study area.

Development and Validation of Girth‐, Volume‐, and Mass‐Based Body Condition Indices for Free‐Swimming Dugongs, via Drone Photogrammetry

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Drone photogrammetry provides a minimally invasive morphometric tool to assess growth and energy reserve in marine mammals. Converting drone‐derived measurements (e.g., body width) into body condition indices (BCIs, residuals from expected body girth, volume, or mass) requires prior knowledge of normative body shape. We developed and validated

Decreasing Sociality With Body Size in All‐Male Groups of Sperm Whales (Physeter macrocephalus)

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The costs and benefits of group living can influence animal group size and social relationships, and these balance points may shift as animals mature. Young male sperm whales (Physeter macrocephalus) appear to form stable all‐male groups unrelated to direct defense of females or territories, but quantitative data on how sociality changes with ...

Diagnostic Accuracy of High‐Resolution Manometry for Assessing Fundoplication Integrity: Validation of the Padova Classification

open access: yesNeurogastroenterology &Motility, Volume 38, Issue 10, October 2026.
The Padova Classification accurately characterized fundoplication function on high‐resolution manometry in 373 patients, showing high sensitivity (88.8%–100%) and specificity (96.9%–97.4%) against a composite reference standard, reliably distinguishing functioning, ineffective, and obstructive fundoplication phenotypes.

Galapagos commentary

open access: yes, 2010
The Galapagos Islands provided one of the first lowland paleoecological records from the Neotropics. Since the first cores were raised from the islands in 1966, there has been a substantial increase in knowledge of past systems, and development of the ...

Thrombomodulin Shapes Thrombo‐Inflammatory Interactions in Lupus Nephritis

open access: yesScandinavian Journal of Immunology, Volume 104, Issue 4, October 2026.
Lupus nephritis is characterized by a distinct thrombo‐inflammatory profile dominated by endothelial activation, with thrombomodulin emerging as the most consistent biological marker of renal involvement in systemic lupus erythematosus. ABSTRACT Lupus nephritis (LN) confers a disproportionate thrombotic risk in systemic lupus erythematosus (SLE) that ...

Structural Heterogeneity Shapes Segmentation of Megathrust Earthquakes and Volcanism in Central America

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.
