Ecology and Evolution, Volume 16, Issue 4, April 2026.We propose a conceptual framework for assessing ecological integrity in hybrid ecosystems based on the identification of active self‐organizing processes and the mapping of their functional contributions. This process‐based approach offers a practical and scalable tool for monitoring ecosystem health and guiding adaptive management strategies in an era

Sequences of Binomial Type with Persistent Roots [PDF]
, 1996 We find all sequences of polynomials (pn)n⩾0with persistent roots (i.e.,pn(x)=cn(x−r1)(x−r2)···(x−rn)) that are of binomial type in Viskov's generalization of Rota's umbral calculus to generalized Appell polynomials.

On an approximation operator and its Lipschitz constant
Journal of Numerical Analysis and Approximation Theory, 2002 In this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a delta operator and a Sheffer sequence for the same delta operator.

The algebra for formal series. II. Sheffer sequences
Journal of Mathematical Analysis and Applications, 1980 In this paper we continue the study of the algebra of formal series. We will develop some new results on special sequences and begin the study of Sheffer Sequences, discussing the important examples of Hermite, Laguerre and Bernoulli. The second section gives a very brief survey of parts of [I] as well as a new result which will be used in the sequel ...

The making of novel ecosystems: A process‐based framework for measurement, analysis and application
Methods in Ecology and Evolution, Volume 17, Issue 3, Page 683-704, March 2026.Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.

The Sheffer B-type 1 Orthogonal Polynomial Sequences [PDF]
, 2009 In 1939, I.M. Sheffer proved that every polynomial sequence belongs to one and only one type. Sheffer extensively developed properties of the B-Type 0 polynomial sequences and determined which sets are also orthogonal.

Linear Recurrences Under Side Conditions [PDF]
, 1980 A linear recurrence is a linear operator which maps rn into rn-1, where (rn) is a (recursive) sequence of functions. If the kernel of this operator consists only of constant functions, uniqueness and representation theorems of (rn) can be stated for the ...
