Local Angler Knowledge Reveals Declines in Fishing Quality for Black Bass in Lakes of Eastern Ontario

Fisheries Management and Ecology, EarlyView.
ABSTRACT Local ecological knowledge can be useful to assess data‐limited fisheries such as the Ontario Black Bass (Micropterus spp.) recreational fishery. We surveyed local anglers using the Life History Calendar approach to determine if there were perceived changes in fishing quality for Black Bass in eastern Ontario across different time periods. For

Hyperstability of Cauchy and Jensen functional equations in 2-normed spaces

Journal of Inequalities and Applications
In this article, with simple and short proofs without applying fixed point theorems, some hyperstability results corresponding to the functional equations of Cauchy and Jensen are presented in 2-normed spaces.

Stability of a Bi-Jensen Functional Equation on Restricted Unbounded Domains and Some Asymptotic Behaviors

Mathematics, 2022
In this paper, we give some properties of the bi-Jensen functional equation and investigate its Hyers–Ulam stability and hyperstability. We construct a function which is bi-Jensen and is not continuous.

Mixed Support for the Temperature‐Size Rule in Wild Freshwater Fishes

Ecology Letters, Volume 29, Issue 2, February 2026.
We use age and length data of 1.4 million fish from 2704 lakes to evaluate the temperature‐size rule in wild populations. We found evidence that warmer environments are associated with faster life histories and reduced lifespans, but this seldom translates to smaller maximum body sizes. A deeper understanding of how temperature shapes growth in natural

Stability of -Jordan Homomorphisms from a Normed Algebra to a Banach Algebra

Abstract and Applied Analysis, 2013
We establish the hyperstability of -Jordan homomorphisms from a normed algebra to a Banach algebra, and also we show that an -Jordan homomorphism between two commutative Banach algebras is an -ring homomorphism.

Characterization, stability and hyperstability of multi-quadratic–cubic mappings

Journal of Inequalities and Applications, 2021
In this paper, we unify the system of functional equations defining a multi-quadratic–cubic mapping to a single equation. Applying a fixed point theorem, we study the generalized Hyers–Ulam stability of multi-quadratic–cubic mappings.

On Asymptotic Behavior of a 2-Linear Functional Equation

Mathematics, 2022
In this paper, we deal with a 2-linear functional equation. The Hyers-Ulam stability of this functional equation is shown on some restricted unbounded domains, and the obtained results are applied to get several hyperstability consequences.

Angler Heterogeneity in Newfoundland and Labrador, Canada: Insights From Nearly Three Decades (1994–2022) of Atlantic Salmon Angler License and Activity Records

Fisheries Management and Ecology, Volume 33, Issue 1, Page 88-104, February 2026.
ABSTRACT Angler demographics and motivations are an important consideration to successful fisheries management. We examined 29 years of angler license and activity records from the recreational Atlantic salmon fishery in Newfoundland and Labrador, Canada to: (1) provide a contemporary evaluation of angler demographic trends; (2) evaluate age and ...

Generalized Hyers–Ulam Stability of the Additive Functional Equation

Axioms, 2019
We will prove the generalized Hyers–Ulam stability and the hyperstability of the additive functional equation f(x1 + y1, x2 + y2, …, xn + yn) = f(x1, x2, … xn) + f(y1, y2, …, yn).
