Summary: Toxin evolution in animals is a complex and fascinating area of scientific research. Understanding the factors that influence toxin evolution, such as genetics and ecology, as well as antagonistic interactions and coevolutionary dynamics, is crucial. By studying toxic Pacific newts and their coevolution with snake predators, we can gain insights into the evolution and ecology of toxins.

Summary: Single-trait models often inhibit diversification, but multiple-trait arms race models can promote it. Coevolution generates adaptive landscapes, determining specific combinations of consumer and resource species. Stable community states depend on stochastic differences along evolutionary pathways.

Summary: This paper investigates the effects of constant time delays on a population dynamics model with Allee effect and weakening memory. Analytical and numerical analyses are conducted to study the role of delays in competition and cooperation. The results demonstrate that time delays can significantly impact the system behavior and offer important insights into underlying biological mechanisms.

Summary: This study investigates the system of two resources and one consumer within the Rosenzweig-MacArthur model, with a Holling type II functional response. The results show that oscillations of C and mutually synchronized R-i are destabilized when consumption rates are modified, leading the system towards fixed points or limit cycles with smaller amplitudes. The consumer is unable to change the preferred resource due to the symmetry between the resources.

Summary: Predator-prey arms races provide ideal models for studying natural selection and adaptive evolution in the formation of biodiversity. This study focused on two closely related sea snakes with different prey preferences. Using proteomic analysis, the researchers found differences in venom composition and toxin-receptor binding activity between the two snakes, which are explained by trophic specialization. Additionally, noncoding RNAs were identified as regulators of toxin gene expression. These findings provide valuable insights into the molecular basis and regulatory mechanisms of venom evolution in response to divergent diets, contributing to the understanding of coselection and coevolution in predator-prey ecosystems.

Summary: In coevolutionary arms races, interacting species impose selection on each other, generating reciprocal adaptations and counter adaptations. The host-specific egg mimicry in the African cuckoo finch is maternally inherited, enabling the evolution of different mimetic traits. However, maternal inheritance and the lack of sexual recombination may hinder the further adaptation of cuckoo finches and impede the ongoing arms races with their individual hosts.

Summary: Antagonistic coevolution between natural enemies can lead to highly exaggerated traits, and this study found that common garter snakes in western North America have evolved conspicuous red coloration as a result of their coevolutionary arms race with toxic prey.

Summary: The study suggests that dormancy can be an effective adaptive strategy to outcompete actively prey, replicating the game-theoretic Parrondo's paradox where two losing strategies combine to achieve a winning outcome. Species with the ability to switch between active and dormant forms can dominate communities through competitive exclusion.

Summary: Antagonistic coevolution between hosts and parasites has important implications in ecology and evolution. This study found that increasing the genetic diversity of parasites may give them an evolutionary advantage in long-term coevolution.

Summary: This work proposes a prey-predator model afflicted with an incurable illness and examines the effect of providing extra food on disease control. The study investigates the model and its disease-free subsystem both theoretically and numerically, exploring local and global bifurcations. Numerical results show that the additional food parameter greatly influences the dynamics of the system and can lead to unexpected bistability and multistability. The infection rate is also found to impact the system's behavior, with the alternative food potentially eradicating the disease even at higher infection rates.

Summary: This paper proves the existence of a unique global positive solution in a stochastic two-patch predator-prey model with ratio-dependent functional responses through the stochastic comparison theorem. It discusses the long-time properties of the solutions pathwise using two different methods and obtains sufficient conditions for extinction and persistence in mean. The results also include discussions on stochastic persistence and the existence of an ergodic stationary distribution, with applications to special models and numerical simulations to support the main results.

Summary: This study investigates the impact of infectious diseases among prey on the dynamics of an eco-epidemic system, and finds that the spread of disease can enhance the chances of predator survival, which is of significant importance for the stability and balance of the ecosystem.

Summary: Propagation of disease in a population with spatial variation raises complex questions. We analyze a predator-prey model with a disease affecting only the predator. We derive analytically the instability conditions for this spatio-temporal model. Using numerical simulations and experimental data, we demonstrate the possibility of travelling waves, periodicity, and chaotic patterns. Our findings show that the introduction of disease can produce Turing patterns in the predator population, while coexistence in non-Turing patterns occurs when infection is absent. This implies that disease persistence may be predictable, but eradication may not be.

Summary: The study introduces a novel approach to track the evolution of absolute fitness and determine when escalatory coevolution results in a switch from mutualism to parasitism. Results show that interactions mediated by a bigger-is-better mechanism tend to evolve towards parasitism, while generalizing the trait-matching mechanism may preserve mutualistic interactions. The study also discusses the consequences of coevolutionary arms races for the maintenance of cheating and the implications of coevolution in a South African pollination network for the evolution of parasitism.

Summary: In this paper, the dynamical behavior of a predator-prey model with discrete time is explored through theoretical analysis and numerical simulation. The existence and stability of four equilibria are analyzed, with Flip bifurcation and Hopf bifurcation occurring at the unique positive equilibrium point. Chaotic cases are observed at some corresponding internal equilibria when small perturbations are applied to the bifurcation parameter. Numerical simulations using maximum Lyapunov exponent and phase diagrams reveal a complex dynamical behavior.

Summary: The aim of this study was to determine if a single-generator approach can be used to model the complex mechanism of periodic leg movements. Through numerical simulations, the researchers developed a phenomenological model and found that the simulated data closely resembled the real polysomnographic data. This provides convincing preliminary support for the validity of the single-generator model.

Summary: Neuroblastoma is a common solid tumor in children, and current multi-modal therapy lacks individualization. This study uses a mathematical model to find personalized chemotherapy schedules based on tumor composition and drug resistance. The optimized schedules improve induction chemotherapy and provide a foundation for targeted therapy in overall multi-modal treatment.
