Evaluating Bayesian Morphological Clocks for Estimating a Dated Phylogeny in a Relict and Fossil‐Rich Family of Wasps (Hymenoptera, Chrysidoidea)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Pulmonary Transit Time Can Be Accurately Quantified From Non‐Arterial Input Function Series in First‐Pass Cardiac Perfusion MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2207-2213, April 2026.
ABSTRACT Purpose Previous studies suggested that arterial‐input‐function (AIF) images are necessary to avoid signal saturation for pulmonary transit time (PTT) measurements. This study challenges that notion by investigating whether PTT can be accurately measured using blood pool signals from myocardial enhancement (non‐AIF) images during resting first‐

Do Consumers Value Diversity in Agriculture? A Choice Experiment

open access: yesApplied Economic Perspectives and Policy, Volume 48, Issue 1, Page 169-181, March 2026.
ABSTRACT Farm ownership in the US today is racially and ethnically homogeneous. Diverse farmers and ranchers make up less than 10% of all producers, they tend to be less financially stable and have tighter profit margins. In the past few years, both government and industry programs have aimed to increase the participation and profitability of diverse ...

Cost‐effectiveness and impact at scale of collaborative care and lecanemab for Alzheimer's disease

open access: yesAlzheimer's &Dementia: Behavior &Socioeconomics of Aging, Volume 2, Issue 1, March 2026.
Abstract INTRODUCTION Advancements in disease‐modifying therapies and collaborative dementia care programs have created opportunities to transform care for people with Alzheimer's disease. METHODS We modeled people aged 71 across three scenarios: 18 months of lecanemab, collaborative care, and combined interventions.
