| ###RSS_DATE### | ||
| Publication date: 1 May 2019Source: Ecological Modelling, Volume 399Author(s): Alexandra I. Klimenko, Yury G. Matushkin, Nikolay A. Kolchanov, Sergey A. LashinAbstractThere are two evolutionary trends in genome organization among microbes: towards either amplification or reduction. Which evolutionary scenario overcomes depends on environmental conditions and the complexity of gene networks determining phenotypic traits such as metabolic features of cells. In this simulation study, we have shown that the habitats characterized by nutrient gradients allow spatial subdivision of evolutionary... | ||

Westbrook, Tavvs M. Alves, Gregory A. SwordAbstractIntegrating population ecology and aeroecology is important for understanding dispersal dynamics of pest insects that depend on aerial habitats. Sugarcane aphid (Melanaphis sacchari) is an economic pest of sorghum in Asia, Africa, Australia, and South America and recently invaded North America, affecting over 90% of the continent’s sorghum production... | ||
| A synthetic ecosystem for the multi-level modelling of heterotroph-phototroph metabolic interactions | ||
| ###RSS_DATE### | ||
| Publication date: 1 May 2019Source: Ecological Modelling, Volume 399Author(s): Marco Fondi, Francesca Di PattiAbstractMarine ecosystems are characterized by an intricate set of interactions. One of the most important occurs through the exchange of dissolved organic matter (DOM) provided by phototrophs and used by heterotrophic bacteria as their main carbon and energy source. This metabolic interaction represents the foundation of the entire ocean food-web.Here we have assembled a synthetic ecosystem to assist the systems-level investigation of this biological association. This was achieved... | ||

| Publication date: 24 April 2019Source: Ecological Modelling, Volume 398Author(s): Hyo Gyeom Kim, Sungwon Hong, Kwang-Seuk Jeong, Dong-Kyun Kim, Gea-Jae JooAbstractThe Nakdong River has suffered from hydrological alterations in the river channel and riverine area during the Four Major Rivers Restoration Project (FMRRP). As these anthropogenic modifications have induced intensive algal blooms, the prediction of algal abundances has become an important issue for securing a source of drinking water and ecosystem stability. This study aimed to assess the changed river system in terms of... | ||
| Modelling population dynamics in mesocosms using an individual-based model coupled to a bioenergetics model | ||
| ###RSS_DATE### | ||
| Publication date: 24 April 2019Source: Ecological Modelling, Volume 398Author(s): Viviane David, Sandrine Joachim, Cleo Tebby, Jean-Marc Porcher, Rémy BeaudouinAbstractDeveloping population models is of great interest as these models enable to extrapolate toxicity observed at the molecular or individual levels to the population level, and thus improve environmental risk assessment of chemical substances. For this purpose, accounting for natural variations of environmental conditions and prey dynamics along with the chemical stress is needed. In this study, an individual-based model (IBM... | ||
| A data-driven modeling approach for simulating algal blooms in the tidal freshwater of James River in response to riverine nutrient loading | ||
| ###RSS_DATE### | ||
| Publication date: 24 April 2019Source: Ecological Modelling, Volume 398Author(s): Jian Shen, Qubin Qin, Ya Wang, Mac SissonAbstractAlgal blooms often occur in the tidal freshwater (TF) of the James River estuary, a tributary of the Chesapeake Bay. The timing of algal blooms correlates highly to a summer low-flow period when residence time is long and nutrients are available. Because of complex interactions between physical transport and algal dynamics, it is challenging to predict interannual variations of bloom correctly using a complex eutrophication model without having a... | ||
| Transient dynamics: Equilibrium, collapse, and extinction in age-structured models. The case of the Northern cod stock | ||
| ###RSS_DATE### | ||
| Publication date: 24 April 2019Source: Ecological Modelling, Volume 398Author(s): José M. Maroto, Manuel MoránAbstractEquilibrium-based methods are widely used in the literature on population ecology to analyze the sustainability of the management strategy. This approach fails to account for many factors such as age-specific natural mortality rates, the cohort survival rates, the possibility of extinction, the characterization of the equilibriums, their stability properties, and transient dynamics. We propose here a method, based on the theory of non-linear dynamic systems, that... | ||
