Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Ant Colony Optimisation – A Proposed Solution Framework for the Capacitated Facility Location Problem

open access: yes
This thesis is a critical investigation into the development, application and evaluation of ant colony optimisation metaheuristics, with a view to solving a class of capacitated facility location problems. The study is comprised of three phases.

Routing design for less-than-truckload motor carriers using ant colony techniques [PDF]

open access: yes, 2004
One of the most important challenges for Less-Than-Truck-Load carriers consists of determining how to consolidate flows of small shipments to minimize costs while maintaining a certain level of service.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

open access: yesJournal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

New medicine for soil restoration: biological soil crust capsules facilitate native plant and soil microbe establishment

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Restoration in drylands is challenging because of harsh climates, requiring creative methods and organisms like biocrusts for restoration of degraded lands. Biocrusts are thin, coherent soil surface layers prevalent in drylands, engineered, and inhabited by communities of organisms including mosses, lichens, and cyanobacteria ...

Self-evolving ant colony optimization and its application to traveling salesman problem [PDF]

open access: yes, 2012
Ant colony optimization (ACO) algorithms are a recently developed, popula- tion-based approach which has been successfully applied to combinatorial optimization problems.

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

A stochastic traffic assignment algorithm based on Ant Colony Optimisation

open access: yes, 2006
In this paper we propose a Stochastic User Equilibrium (SUE) algorithm that can be adopted as simulation model in the design problem or in the real-time management of transportation systems when cost functions (i.e.

A genetic algorithm simheuristic for solving the stochastic project portfolio selection problem with portfolio reliability constraints

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 4039-4071, November 2026.
Abstract In response to the increasing complexity of modern products, dynamic markets, and intensified competition, project‐based organizations are actively seeking methodologies to efficiently manage their expanding project portfolios. This paper analyzes the project portfolio selection problem in uncertain environments. Despite recent advances in the
