Increasing absolute prey density within a mimicry complex protects aposematic models and their Batesian mimics

Abstract Batesian mimicry is a defensive adaptation where predators learn to avoid aposematic prey and generalize their warning signals to phenotypically similar mimics. The phenotypic accuracy needed for mimics to benefit from this adaptation depends on the relative densities of...

Linking social attention to reproductive state and future reproduction in female monkeys

Abstract The demands of complex social life are thought to drive the evolution of cognition in primates. One important approach to testing this hypothesis is to assess if variation in psychological processes impacts an individual’s fitness outcomes, but this can be challenging in...

Preliminary investigation into the maternal‐embryo stable isotope dynamics and nutrient routing in an oophagous elasmobranch, the Common Thresher Shark ( Alopias vulpinus )

Abstract Two opportunistic sampling events were used to analyse the isotopic composition of different tissue constituents (protein and lipid) to explore maternal investment routing pathways from pregnant Common Thresher Sharks ( Alopias vulpinus ) to their near‐term embryos. Prot...

Strengthening Youth Crisis Reporting and Response: Development of a Practice-Based Systems Maturity Model

Youth suicide prevention and crisis response require coordinated action across public health, behavioral health, education, health care, law enforcement, and community systems. However, local jurisdictions often lack practical tools to assess system readiness and prioritize syste...

Map Orientation Impact on Spatial Acquisition During a Memory Task

Navigational systems are widely used to support wayfinding, yet concerns remain about their impact on spatial learning. This study examined how map rotation and working memory demands influence the extraction of spatial and nonspatial information from GPS style displays. In a mix...

The Structural Geography of Firearm Violence: Poverty, Opportunity and Shooting Victim Concentrations in Philadelphia, Pennsylvania

In the United States, firearm violence remains highly concentrated within a relatively small number of urban neighborhoods despite substantial post-pandemic declines in shootings across many cities. This study examines whether enduring poverty and neighborhood structural and oppo...

Layer-Controlled Intermolecular Coupling and Many-Body Effects in C60 Films

Abstract Crystalline C60 is a molecular solid whose electronic properties emerge from the interplay of intermolecular hopping, electron correlations, and electron–vibration coupling. Unlike moiré van der Waals heterostructures, where the interaction strength is commonly tuned by...

Integrated Supports: Perspectives from Adults with Intellectual and/or Developmental Disabilities

Abstract All individuals need supports throughout their lives. Individuals with intellectual and/or developmental disabilities (IDD) may rely on integrated supports – a combination of formal (i.e., paid supports provided by service providers) and natural supports (i.e., unpaid su...

Customer Trustworthiness and Procedural Fairness on Relationship Marketing Performance of Food Suppliers in Multi-Customer Relationships

This study examines how a food supplier’s perceptions of customer trustworthiness relate to its customer concentration, the extent to which a supplier’s sales are unevenly distributed across its major customers, and how customer concentration is associated with procedural fairnes...

Clinical Reasoning Under Uncertainty in Speech-Language Pathology When Measures, Labels, and Best-Practice Claims Get Ahead of Evidence

Purpose: Speech-language pathologists often have to make consequential decisions with evidence that is incomplete, indirect, or mixed. The risk is not uncertainty itself, but the way an indirect measure, a familiar label, or a best-practice statement can begin to carry more inter...

Magnetized Dense Matter in the Nambu–Jona–Lasinio Model and Its Applications to Compact Stars

We review the properties of strongly interacting matter under the influence of an external magnetic field, with emphasis on results obtained using the Nambu–Jona–Lasinio model and its variants. Strong magnetic fields, relevant for heavy-ion collisions and magnetars, introduce mod...
