Simulating crop-disease interactions in agricultural landscapes to analyse the effectiveness of host resistance in disease control: The case of potato late blight
24. Juni 2018
Publication date: 24 June 2018 Source:Ecological Modelling, Volume 378 Author(s): Francine C.A. Pacilly, Gert Jan Hofstede, Edith T. Lammerts van Bueren, Geert J.T. Kessel, Jeroen C.J. Groot Disease-resistant potato varieties can play a key role in sustainable control of potato late blight. However, when these varieties are more widely used, resistance breakdown can occur as a result of pathogen adaptation. Here we focussed on potato cultivation in the Netherlands, where new (single gene) resistant varieties have been introduced over the last ten years. This new generation of...

Publication date: 10 June 2018 Source:Ecological Modelling, Volume 377 Author(s): Meiling Sheng, Junzhi Liu, A-Xing Zhu, David G. Rossiter, Liming Zhu, Guoqiang Peng Climate change has significant impacts on crop yields and could greatly affect global food security. As an advanced process-based land surface model, the Community Land Model (CLM) includes a comprehensive crop model (CLM-Crop), which aims to simulate crop growth globally. Although this model has been evaluated in the United States, it is not clear whether it can be applied successfully in other parts of the...

Modelling assessment of interactions in the Black Sea of the invasive ctenophores Mnemiopsis leidyi and Beroe ovata
24. Mai 2018
Publication date: 24 May 2018 Source:Ecological Modelling, Volume 376 Author(s): Shiganova Tamara A., Elena Alekseenko, Moskalenko Lidia, Nival Paul We analyzed the main factors that controlled the prey-predator dynamics of two invasive ctenophores, Mnemiopsis leidyi and Beroe ovata in the Black Sea using a demographic model. We assessed the bottom up cascading effect from edible zooplankton to its consumer M. leidyi and its predator B. ovata. For these purposes, we used life cycles of both ctenophores (ova, larva, juvenile, transitional and adult stages), variability of annual...

Plastic tree crowns contribute to small-scale heterogeneity in virgin beech forests—An individual-based modeling approach
24. Mai 2018
Publication date: 24 May 2018 Source:Ecological Modelling, Volume 376 Author(s): Markus Engel, Michael Körner, Uta Berger Old-growth beech (Fagus sylvatica L.) forests in Europe show a structural heterogeneity, which distinguish from managed ones. Recent investigations revealed that facilitative belowground interactions might counteract aboveground competition for light. However, the exact interaction of these mechanisms is unclear. We developed the BEEchPlasticity (BEEP) model to investigate whether the mere focus on the aboveground competition for canopy space with subsequent...

The process of connectivity loss during habitat fragmentation and their consequences on population dynamics
24. Mai 2018
Publication date: 24 May 2018 Source:Ecological Modelling, Volume 376 Author(s): Fernando Córdova-Lepe, Rodrigo Del Valle, Rodrigo Ramos-Jiliberto Understanding the processes and consequences of habitat fragmentation is highly relevant since it represents a serious threat to biodiversity. However, fragmentation includes several facets that are difficult to dissect, such as loss of habitat connectivity, edge effects, and habitat loss. In this study, we analyze by mathematical and computational means a single isolated component of habitat fragmentation: the loss of connectivity...

Modelling weed and vine disturbance in tropical forests after selective logging and clearcutting
10. Mai 2018
Publication date: 10 May 2018 Source:Ecological Modelling, Volume 375 Author(s): Roberto Cazzolla Gatti Although tropical rainforests preserve high levels of biodiversity, they are among the most threatened ecosystems globally due to large-scale fragmentation as a result of anthropogenic activities. Overall, fast human-driven habitat destruction is suspected to be one of the major causes of species extinction. The mosaic of vegetation types, which contributes to the incredible diversity of the tropics is highly impacted by large-scale fragmentation. The main causes of such habitat...
Metapopulation mirages: Problems parsing process from pattern
10. Mai 2018
Publication date: 10 May 2018 Source:Ecological Modelling, Volume 375 Author(s): Natasha A. Urban, Stephen F. Matter Ecological models attempting to unite the concepts of biodiversity and biogeography have been used to describe and predict the distribution and abundance of species. Two mechanistic hypotheses, the neutral model and the community-level metapopulation model, have the potential for direct comparison. However, there is potential for incorrectly inferring the underlying mechanisms of observed data if the hypotheses have similar descriptive ability. In this paper, we...
