Summary: Microbial communities are crucial for natural processes and are closely linked to species metabolism. Researchers are reevaluating consumer-resource models to better understand the dynamics of microbial communities. The study explores proteome allocation in relation to microbial growth and aims to determine conditions for species coexistence in systems with multiple resources.

Summary: Many species are annual breeders who consume resources and may die between reproductive events. A model for such life cycles needs to represent both the discrete- and continuous-time processes in the community. The dynamics of multiple discrete breeders on a single resource reveal coexistence mechanisms and complex dynamics.

Summary: This study incorporates stoichiometry into a chemostat culture model and examines the dynamics and competition results of single and multiple algae species. The results show that increased phosphorus input or slower dilution rate promotes the persistence of algae species, while stoichiometry facilitates coexistence of competing algae species. The study concludes that under low phosphorus input or fast dilution rate, competitive exclusion still occurs, but high phosphorus input or slow dilution rate enables the coexistence of multiple species.

Summary: This study investigates the evolutionary impact of temporal periodicity and spatial heterogeneity on population ecology. By analyzing the dynamics of a competition-diffusion system with different interspecific competition coefficients, the study provides conditions for the interplay between diffusion intensities, interspecific competition coefficients, and their effects on coexistence and competitive exclusion.

Summary: Genetic heterogeneity plays a crucial role in the interaction of microorganisms, and the competitive exclusion principle is the main governing principle for disease competition. This paper studies the dynamics of a two-strain SIS epidemic model on complex networks and derives the reproduction numbers associated with each strain. It is proven that the competitive exclusion principle holds globally and the endemic equilibrium uniquely and globally coexists.

Summary: In this paper, the population dynamics of a general competitive parabolic system with both diffusion and advection are investigated. The global dynamics are determined by values of competition coefficients b and c, with a clear picture on the local dynamics of semi-trivial steady states provided. The results in this study greatly extend those in a previous work by removing certain conditions.

Summary: Savannas, which cover a significant portion of the Earth's land surface, are characterized by the persistent coexistence of C-3 trees and C-4 grasses. However, the mechanisms explaining this coexistence are still debated. Existing quantitative models have contrasting assumptions about the responsible mechanisms. This study shows that a single model cannot fully explain the coexistence, but combining elements from different models can provide a synthesis that incorporates both Walter's two-layer model and demographic bottlenecks. Functional rooting separation is proposed as a necessary factor for coexistence, supported by empirical evidence and the grasses' advantage in soil moisture acquisition.

Summary: This research focuses on the robustness analysis in model reduction, which is particularly relevant for engineered biological systems. By providing robustness guarantees under parametric uncertainties, an automated model reduction method is proposed to determine the best possible reduced model for a given system model.

Summary: The study focused on a periodic Kolmogorov system describing nonlinear competition between two species. The researchers discussed coexistence and extinction scenarios for both species, as well as the domain of attraction of nontrivial periodic solutions on the axes, under generalized Gopalsamy conditions. The results were further applied to models of microbial growth and phytoplankton competition under toxin influence.

Summary: This research investigates the dynamics of competitive Kolmogorov systems formulated in a semi-Markov regime-switching framework. It establishes sharp sufficient conditions for species coexistence and competitive exclusion, as well as estimates the convergence rate of transition probabilities in the case of species coexistence. Additionally, the study proposes a method for proving the exponential convergence of transition probabilities in population models driven by a semi-Markov process.

Summary: In this paper, a novel strategy is proposed to improve the performance of physics-based models of dynamical systems by using continuous simulation and deterministic data allocation. The strategy addresses the challenge of ensuring distributional similarity in partitioning data into independent subsets. The results of testing on rainfall-runoff models demonstrate that the proposed strategy consistently outperforms the traditional approach, especially under conditions of larger runoff skewness.

Summary: This article focuses on the robust D-stabilization analysis of fractional-order control systems and introduces a necessary and sufficient condition for the robust D-stabilization of the closed-loop control system. The geometric pattern of the value set of the characteristic polynomial is obtained analytically, and a new function is provided to determine the D-stability robustness radius. The achieved results are applicable to systems of incommensurate order and are demonstrated through numerical simulations and practical experiments.

Summary: This article investigates the robustness of an uncertain nonlinear system by approximating the system with a linear time-varying system and describing the perturbation with integral quadratic constraints. The analysis provides a computational method for bounding the worst-case performance without using heuristics like time gridding.

Summary: Ilse Rosenthal-Schneider, a refugee immigrant to Australia in 1938, was a student of Nobel Prize-winning physicists, Einstein, Planck, and von Laue. She combined a background in physics with a philosophical focus on the nature of knowledge. She not only taught science students at the University of Sydney but also conducted science outreach programs in regional towns of New South Wales, where she was highly acclaimed as a science communicator.

Summary: The principle of microbial infallibility, which states that microorganisms will always find a way to utilize environmental resources for energy gain, has a long history in microbial physiology. Recent discoveries have reignited interest in this principle and highlighted its importance in contemporary metagenomics research. Hypothesis-driven metagenomics can benefit from the assumptions of microbial infallibility, allowing for the formulation and testing of hypotheses with the help of enrichment cultures and other strategies.

Summary: The theory of Selected Effects explains function in biology as the effect of past traits that contributed to the current existence of a trait. However, it is critiqued for its inability to account for the introduction of new functions and for neglecting the physical work involved in function.
