Abstract Autotrophs play an essential role in the cycling of carbon and nutrients, yet disease‐ecosystem relationships are often overlooked these dynamics. Importantly, availability elemental nutrients like nitrogen phosphorus impacts infectious disease autotrophs, can induce reciprocal effects on ecosystem nutrient Relationships linking with dynamics bidirectional, though interdependence processes has received little attention. We introduce disease‐mediated (DND) as a framework to describe...
<p>Identifiability of a mathematical model plays crucial role in the parameterization model. In this study, we established structural identifiability susceptible-exposed-infected-recovered (SEIR) given different combinations input data and investigated practical with respect to observable data, frequency, noise distributions. The was explored by both Monte Carlo simulations correlation matrix approach. Our results showed that benefits from higher frequency peak an outbreak. incidence...
Abstract An overlooked effect of ecosystem eutrophication is the potential to alter disease dynamics in primary producers, inducing disease‐mediated feedbacks that net productivity and elemental recycling. Models ecology rarely track organisms past death, yet death from infection can important processes including recycling rates nutrient supply living hosts. In contrast, models dynamics, pools (e.g. nitrogen, phosphorus) regulate pathogen reproduction transmission. Thus, both stand grow as...
Death is a common outcome of infection, but most disease models do not track hosts after death. Instead, these disappear into void. This assumption lacks critical realism, because dead can alter host–pathogen dynamics. Here, we develop theoretical framework carbon‐based combining and ecosystem perspectives to investigate the consequences feedbacks between living on dynamics carbon cycling. Because autotrophs (i.e. plants phytoplankton) are regulators cycling, developed general model...
Human‐induced changes in biogeochemical cycles alter the availability of carbon (C), nitrogen (N) and phosphorus (P) environment, leading to elemental stoichiometry primary producers. These ratios may, turn, degree stoichiometric mismatch between producer hosts their pathogens. Here, we outline how ecological could be used as a framework predict effects changing nutrient supply on mismatches autotroph–pathogen interactions. We discuss empirical evidence linking pathogen performance arising...
Intraguild predation is a common ecological phenomenon that manifests itself by the aggression of one predator another to obtain shared prey species. In this paper, we develop discrete analog stoichiometric continuous-time intraguild model. We analyze dynamics discrete-time model, such as boundedness and invariance, stability equilibria, features matrices. The dynamic behavior two models compared analyzed through numerical analysis. observe same coexistence region populations effects food...
Hosts rely on the availability of nutrients for growth, and defense against pathogens. At same time, changes in host nutrition can alter dynamics pathogens that their reproduction. For primary producer hosts, enhanced nutrient loads may increase biomass or pathogen reproduction, promoting faster density-dependent transmission. However, effect elevated be reduced if hosts allocate a growth-limiting to defense. In canonical disease models, transmission is not function availability. Yet,...

In this study, we establish structural identifiability Susceptible-Exposed-Infected-Recovered (SEIR) given different combinations input data and investigate practical with respect to observable data, frequency, noise distributions.

Many population systems are subject to seasonally varying environments. As a result, many species exhibit seasonal changes in their life-history parameters. It is quite natural try understand how forcing affects dynamics stoichiometric constraints, such as nutrient/light availability and food quality. Here, we use variation of Lotka-Volterra type model, known the LKE case study, focusing on producer's light-dependent carrying capacity. Positivity boundedness model solutions studied, well...
Abstract Ecological stoichiometry is the study of balance multiple elements in ecological interactions and processes (Sterner Elser Stoichiometry: The Biology Elements from Molecules to Biosphere, 2002). Modeling under this framework enables us investigate effect nutrient content on organisms whether imbalance involves insufficient or excess content. This phenomenon called “stoichiometric knife-edge”. In paper, a discrete-time predator–prey model that captures established qualitatively...
