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

Ecography, 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.

Dynamic complexity of a discretized predator-prey system with Allee effect and herd behaviour

Applied Mathematics in Science and Engineering
This paper investigates the dynamics of a discrete-time predator-prey system in which the prey population is impacted by the Allee effect. Possible fixed points in the system are studied for their existence and topological categorization.

Stochastic colonization, transient and boom–bust dynamics shape invasions by native taxa

Ecology, Volume 107, Issue 5, May 2026.
Abstract Boom–bust dynamics (BBD) is a population dynamic pattern described in invasion ecology, where a population suddenly increases (boom) before quickly declining (bust), eventually stabilizing at much lower levels. This initial outbreak is considered a transient phase preceding a long‐term population equilibrium.

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

Oikos, 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

Light‐Modulated Humidity Sensing in Spiropyran Functionalized MoS2 Transistors

Small, Volume 22, Issue 25, 4 May 2026.
A hybrid material combining molybdenum disulfide (MoS2) and spiropyran for humidity and light responsiveness is developed. Ultraviolete (UV) irradiation tunes the wettability of MoS2 decorated by spiropyran, enhancing the humidity sensitivity. Water adsorption and photochromic doping significantly alter the optoelectronic properties of MoS2 flakes ...

Stability and bifurcation analysis of a discrete-time plant-herbivore model with chaotic dynamics under weak Allee effect on plant

Franklin Open
In this paper, we propose a discrete-time plant-herbivore model incorporating the weak Allee effect on plant populations to investigate the complex dynamics of ecological interactions.

Integrating ecological feedbacks across scales and levels of organization

Ecography, Volume 2026, Issue 5, May 2026.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Stochastic Forces in Microbial Community Assembly: Founding Community Size Governs Divergent Ecological Trajectories

Ecology Letters, Volume 29, Issue 5, May 2026.
The processes driving community assembly are broadly categorised into deterministic and stochastic ones. With a multi‐replicated experimental design, we quantified the extent to which stochasticity at initial stages of community assembly could drive divergence into alternative ecological trajectories.
