Some Identities on Degenerate Bernstein and Degenerate Euler Polynomials

Mathematics, 2019
In recent years, intensive studies on degenerate versions of various special numbers and polynomials have been done by means of generating functions, combinatorial methods, umbral calculus, p-adic analysis and differential equations.

Assessing and quantifying variations in the functioning of marine food webs across scales

Conservation Biology, EarlyView.
Abstract The mismatch between the scale of ecological processes and management decisions represents a significant challenge in marine conservation. This misalignment can result in ineffective conservation measures and compromise the sustainability of marine ecosystems.

Non-linear sigma models on K3 and Umbral Moonshine [PDF]

, 2022
In this thesis we study some aspects of non-linear sigma models on K3 surfaces, a particular case of N=(4,4) superconformal field theories which are widely studied in the context of string compactification.

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Functional Ecology, Volume 40, Issue 11, Page 3577-3591, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed.

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, Volume 40, Issue 11, Page 3398-3421, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

A Museum‐Curated, Voucher‐Backed 12S Barcode Reference Library for Fishes of the Ecuadorian Amazon

Molecular Ecology Resources, Volume 26, Issue 8, November 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding is an emerging method that promises to expedite and improve biodiversity surveys by identifying species from the genetic material they shed into the environment. eDNA methods offer many advantages over conventional specimen‐based surveys, but their effectiveness hinges on reference libraries, which for ...

Beyond Evidence: How Framing Shapes Public Health Policies During Health Crises

Policy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT Does the level of evidence that accompanies policy action depend on how a problem is framed, and on who frames it? This article examines these questions in the context of health crises. Bridging sociological and equivalence framing theories, it treats frames as preexisting interpretive schemes shared within communities of actors, whose ...
