Fine-scale plant defence variability increases top-down control of an herbivore
Ryan Paul, Ian S. Pearse, Paul J. Ode
2021, Functional Ecology (35) 1437-1447
Herbivore populations are regulated by a combination of plant defences and natural enemies. While plant defence can suppress herbivore populations, these defences can also adversely affect natural enemies, thereby releasing herbivores from top-down control.Over their life spans, herbivores and their natural enemies may experience substantial variation in plant defence....
Evaluation of riverbed magnetic susceptibility for mapping biogeochemical hot spots in groundwater-impacted rivers
Cheng-Hui Wang, Martin A. Briggs, Frederick Day-Lewis, L. Slater
2021, Hydrological Processes (35)
Redox hot spots occurring as metal-rich anoxic groundwater discharges through oxic wetland and river sediments commonly result in the formation of iron (Fe) oxide precipitates. These redox-sensitive precipitates influence the release of nutrients and metals to surface water and can act as ‘contaminant sponges’ by absorbing toxic compounds. We explore...
