Review of spatial analysis of urban carbon metabolism
Publication date: 10 March 2018 Source:Ecological Modelling, Volume 371 Author(s): Yan Zhang, Qiong Wu, Brian D. Fath Urban areas have contributed 75% of the global CO2 emissions. Therefore, seeking global carbon reduction solutions from the perspective of city has become a focus of decision-makers in charge of environmental protection. The carbon emission reduction potential in land management and spatial adjustment has become an important mean for achieving regional and global sustainable development. In this paper, we systematically review and synthesize four main aspects of...

In order to successfully deal with these challenges, we need comprehensive approaches that integrate knowledge from multiple disciplines and perspectives and emphasize interconnections. In short...
Dome-shaped transition between positive and negative interactions maintains higher persistence and biomass in more complex ecological networks
24. Februar 2018
Publication date: 24 February 2018 Source:Ecological Modelling, Volume 370 Author(s): Chuan Yan, Zhibin Zhang Positive relationship between diversity and biomass was often observed by empirical experiments at the community level, but the effects of species interactions on community total biomass have been rarely explored from a network perspective. Weak interaction and specific non-monotonic interactions have been proposed to be stabilizing mechanisms in maintaining persistence in more complex ecosystems, but it is unclear how they contribute to the high level of biomass or...
A spatially explicit agent-based simulation model of a reservoir host of cutaneous leishmaniasis, Rhombomys opimus
24. Februar 2018
Publication date: 24 February 2018 Source:Ecological Modelling, Volume 370 Author(s): Mohammadreza Rajabi, Ali Mansourian, Petter Pilesjö, Mohammad Reza Shirzadi, Reza Fadaei, Javad Ramazanpour Rhombomys opimus (R. opimus), a social rodent, is the main reservoir host for zoonotic cutaneous leishmaniasis (ZCL) in most parts of the Middle East and central Asia. The difficulties in monitoring rodent population patterns have hindered the effective application of preventive measures of ZCL. This study presents a spatially explicit agent-based simulation model of R. opimus...
Predicting Heliothis (Helicoverpa armigera) pest population dynamics with an age-structured insect population model driven by satellite data
10. Februar 2018
Publication date: 10 February 2018 Source:Ecological Modelling, Volume 369 Author(s): Moshe Blum, David Nestel, Yafit Cohen, Eitan Goldshtein, David Helman, Itamar M. Lensky The cotton bollworm (Helicoverpa armigera) is among the most damaging agricultural insect pests in the world. The life cycle of H. armigera is temperature dependent and as such modeling its population dynamics for integrated pest management (IPM) purposes requires accurate temperature information throughout the area of interest, which is not always available. We present, for the first time, a continuous...
Integrating spatio-temporal variation in resource availability and herbivore movements into rangeland management: RaMDry—An agent-based model on livestock feeding ecology in a dynamic...
10. Februar 2018
Publication date: 10 February 2018 Source:Ecological Modelling, Volume 369 Author(s): Pascal Fust, Eva Schlecht Fast growth of the human population puts high pressure on pasture habitats due to increasingly high grazing intensities on shrinking grazing land. Adapted herbivore management is needed to maintain the long term productivity of the rangeland ecosystem, especially in dry climates where precipitation is highly erratic and where forage yield and quality of the pasture are highly dynamic. We used an agent-based approach to develop a spatially explicit model for a case study...

Sensitivity of WOFOST-based modelling solutions to crop parameters under climate change
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Carlo Gilardelli, Roberto Confalonieri, Giovanni Alessandro Cappelli, Gianni Bellocchi The formalization of novel equations explicitly modelling the impact of extreme weather events into the crop model WOFOST (EMS: existing modelling solution; MMS: modified modelling solution) is proposed as a way to reduce the uncertainty in estimations of crop yield. A sensitivity analysis (SA) was performed to assess the effect of changing parameters values on the yield simulated by the model (both EMS and...
An integrated stochastic economic-ecological-social model with stratified-population
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Pablo T. Rodriguez-Gonzalez, Ramiro Rico-Martinez, Vicente Rico-Ramirez There has been a growing interest on the study of the human-ecosystems sustainability from an integrated point of view. The recognition of sustainability as a complex long-term problem has led to the development of tools that address it from a multidisciplinary perspective. Several mathematical models have been developed to support the understanding of the interactions between human activities and natural resources, and the...
Patch dynamics of various plant-animal interactions in fragmented landscapes
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Zhichao Xu, Yang Shen, Jinbao Liao Habitat destruction, characterized by patch loss and patch fragmentation, has been recognized as one of leading factors driving species loss. Although some studies have already explored how patch loss affects metacommunity dynamics, the effect of patch configurational fragmentation remains vaguely understood. Here we construct a patch-dynamic model for various plant-animal interactions in fragmented landscapes, including neutralism (0, 0), poison (0...

The course employed extensive use of outdoor field laboratories at a nearby park, which had multiple ecological habitats. The main progression was...
Long-term structural and functional changes driven by climate variability and fishery regimes in a sandy beach ecosystem
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Diego Lercari, Omar Defeo, Leonardo Ortega, Luis Orlando, Ignacio Gianelli, Eleonora Celentano Structural and functional changes in a sandy beach ecosystem in the southwestern Atlantic (Barra del Chuy, Uruguay) were assessed by contrasting four Ecopath trophic models and performing temporal dynamic simulations using Ecosim. Each model (1982, 1989, 1996 and 2012) represents a historical period of a clam fishery in which regulatory structure, management tools and resource status varied...
Responses of the terrestrial carbon cycle to drought over China: Modeling sensitivities of the interactive nitrogen and dynamic vegetation
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Binghao Jia, Yuanyuan Wang, Zhenghui Xie Drought can trigger both immediate and time-lagged responses of terrestrial ecosystems and even cause sizeable positive feedbacks to climate warming. In this study, the influences of interactive nitrogen (N) and dynamic vegetation (DV) on the response of the carbon cycle in terrestrial ecosystems of China to drought were investigated using the Community Land Model version 4.5 (CLM4.5). Model simulations from three configurations of CLM4.5 (C, carbon cycle...
Sustainability factors in dynamical systems modeling: Simulating the non-linear aspects of multiple equilibria
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Joseph W. Dorsey, Leon C. Hardy What is sustainability? Sustainability is a concept that can be defined in many ways depending upon a society's perception of current material needs and the actual material needs of future generations. Much of our ability to achieve sustainability entails developing indicators and measurements that will guide us to this goal. This paper suggests that we can strengthen the prediction of sustainability indicators by adopting a “multiple equilibria” approach for a...
A hierarchical modelling framework for assessing physical and biochemical characteristics of a regulated river
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Andrew W. Tranmer, Clelia L. Marti, Daniele Tonina, Rohan Benjankar, Dana Weigel, Leticia Vilhena, Claire McGrath, Peter Goodwin, Matthew Tiedemann, Jim Mckean, Jörg Imberger Regulated rivers below dams have traditionally been managed using a minimum instream flow to provide adequate aquatic habitat. However, dam management, in conjunction with changes in climate and land use, challenges downstream ecosystem functions that cannot be properly addressed by a simple minimum flow...
Food web dynamics in trophic hierarchies
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Anett Endrédi, Vera Senánszky, Simone Libralato, Ferenc Jordán Using network analysis for making predictions about food web dynamics is one of the major challenges in systems ecology. Since there are several notoriously difficult methodological problems with food webs, only a comparative perspective can help. We study a standard database for trophic flow networks and analyse the correlation between structure and dynamics in strictly hierarchical food webs (directed acyclic graphs, DAGs). To...
Quantitative predictions from competition theory with an incomplete knowledge of model parameters tested against experiments across diverse taxa
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Hugo Fort The capacity of community ecology for making quantitative predictions is often limited by incomplete empirical information which precludes obtaining reasonable estimates of model parameters. This is particularly the case for communities with large species richness S since it is practically impossible to perform the S monoculture experiments (to obtain the species carrying capacities) plus the S ×(S −1)/2 pairwise experiments (required to estimate the entire set of interspecific...
Mathematical modelling for phytoplankton distribution in Sundarbans Estuarine System, India
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): Tanaya Das, Saranya Chakraborti, Joydeep Mukherjee, Goutam Kumar Sen Mathematical modeling is an important tool to study planktonic ecosystem dynamics and various mechanisms involved in its interaction with hydrological regime. The difficulty arises when describing plankton dynamics under wide range of estuarine environmental conditions due to inadequate knowledge to interpret the mechanism to which the environmental nature of a given situation force the model condition towards the observation...
Natural capital and environmental flows assessment in marine protected areas: The case study of Liguria region (NW Mediterranean Sea)
24. Januar 2018
Publication date: 24 January 2018 Source:Ecological Modelling, Volume 368 Author(s): C. Paoli, P. Povero, E. Burgos, G. Dapueto, G. Fanciulli, F. Massa, P. Scarpellini, P. Vassallo A methodology based on emergy analysis for the calculation of the biophysical value of the stocked biomass (natural capital) was applied to the Marine Protected Areas (MPAs) of Portofino (PF) and Cinque Terre (CT). The resources exploited, on a yearly base, to maintain the natural capital itself alive (environmental flows) were accounted too. Emergy analysis is an accounting method useful to...
