A Bit of Sex Stabilizes Host+Parasite Dynamics

Flatt, Thomas ; Maire, Nicolas ; Doebeli, Michael

In: Journal of Theoretical Biology, 2001, vol. 212, no. 3, p. 345-354

To date, only a few studies have focused on the effects of sex on population dynamics. Previous models have typically found that sexual reproduction dampens population fluctuations. Although asexual and sexual reproduction are just the two endpoints along a continuum of varying rates of sex, previous work has ignored the effects of intermediate degrees of sex on population dynamics. Here we study...

A gardener’s influence on urban soil quality

Tresch, Simon ; Moretti, Marco ; Le Bayon, Renée-Claire ; Mäder, Paul ; Zanetta, Andrea ; Frey, David ; Fliessbach, Andreas

In: Frontiers in Environmental Science, 2018, vol. 6, p. -

Gardens are hot spots for urban biodiversity and provide habitats for many plant and animal species, both above- and below-ground. Furthermore, gardens provide a wide range of ecosystem services, including carbon (C) storage and nutrient cycling. Although the soil is the foundation of sustainable gardens providing those ecosystem services, very little is known about the consequences of garden...
