Immigration and Trade in Portugal: A Static and Dynamic Panel Data Analysis [PDF]

open access: yes
This article tests the relation between immigration and Portuguese bilateral trade, considering the fifteen European partners (EU15). Using a static and dynamic panel data analysis, the results show that the stock of immigrants has a positive effect on ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

From niche theory to demographic realities: the demographic niche concept for understanding range‐wide population dynamics

open access: yesEcography, Volume 2026, Issue 5, May 2026.
The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

Between Consistency and Adaptation: How Middle Managers Shape Compensation System Implementation

open access: yesHuman Resource Management, Volume 65, Issue 3, Page 705-729, May/June 2026.
ABSTRACT The success of a human resource management (HRM) system or subsystem, such as a compensation system, hinges on its implementation—yet the microfoundations of this process remain underexplored. To address this gap, we conducted two studies. Study 1 surveyed middle managers and employees in six organizations to examine their attributions of ...

Urinary Extracellular Vesicles for High‐Precision Bladder Cancer Subtyping and Prognosis

open access: yesJournal of Extracellular Biology, Volume 5, Issue 5, May 2026.
ABSTRACT Bladder cancer (BCa) exhibits molecular heterogeneity that complicates early diagnosis and prognosis, and drives confounding clinical outcomes. Non‐muscle invasive and muscle‐invasive subtypes, especially for intermediate to high grade, carry a 25%–50% progression‐free survival rate, underscoring the need for high‐precision prognostic strategy.

Propagation and Depropagation Kinetics of Tetrahydrofurfuryl Methacrylate Investigated by PLP‐SEC

open access: yesMacromolecular Chemistry and Physics, Volume 227, Issue 9, 15 May 2026.
The propagation and depropagation kinetics of the bio‐based monomer tetrahydrofurfuryl methacrylate (THFMA) were quantified via PLP‐SEC over a wide temperature range (10∘C$^\circ{\rm C}$–160°C). Beyond that, lauryl methacrylate (LMA) was investigated as a reference system.

Individual variation in perceived density of conspecifics and its impacts on the realization of ecological niches

open access: yesOikos, Volume 2026, Issue 5, May 2026.
Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception

Solar Wind‐Magnetosphere‐Ionosphere Coupling During the October 2024 Storms

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Two geomagnetic storms occurred in October 2024 (Oct 6‐9 and 10–12), driven by the impact of a series of interplanetary coronal mass ejections on the magnetosphere. The first was a moderate storm, with peak Sym‐H near −150 nT, whereas the second was intense, Sym‐H reaching −340 nT.

Latitudinal Gradients of Species Richness in Marine Benthos: Insights From Japan's Tidal Flat Areas

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
Latitudinal diversity gradients in species richness were observed in the coasts of Japan. Extensive tidal flats and biogeographical connectivity to the Eurasian Continent may cause the unexpected peak in species diversity at the Kyushu region. Mollusca was the dominant taxonomic group, followed by Malacostraca, Annelida, and other benthic groups ...

Navigating Pandemic Hardships: Experiences of Food Insecurity in Racially/Ethnically Diverse Adults in Canada

open access: yesSociology of Health &Illness, Volume 48, Issue 4, May 2026.
ABSTRACT The COVID‐19 pandemic highlighted the health, economic and social inequities among adults in food‐insecure households. Stigma can exacerbate household food insecurity (HFI) by limiting access to vital resources, including nutritious food. We explored the following among racially/ethnically diverse adults in food‐insecure households in Canada: (
