Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...

Eurasian watermilfoil biomass associated with insect herbivores in New York [PDF]
A study of aquatic plant biomass within Cayuga Lake, New York spans twelve years from 1987-1998. The exotic Eurasian watermilfoil ( Myriophyllum spicatum L.) decreased in the northwest end of the lake from 55% of the total biomass in 1987 to 0.4 ...

Ecological biomechanics of marine macrophytes
AbstractMacroalgae and seagrasses in coastal habitats are exposed to turbulent water currents and waves that deform them and can rip them off the substratum, but that also transport essential water-borne substances to them and disperse their propagules and wastes.

We experimentally disrupted below‐ground microbial communities to test their role in the growth and survival of the seagrass Zostera muelleri under two marine heatwave scenarios. Seagrass leaf growth declined with rhizosphere microbiome disruption across all temperature and sediment conditions.

Modelling fixed plant and algal dynamics in rivers: an application to the River Frome [PDF]
The development of eutrophication in river systems is poorly understood given the complex relationship between fixed plants, algae, hydrodynamics, water chemistry and solar radiation.

Abstract Environmental stochasticity in abiotic factors is inherent to ecosystems and is exacerbated by global change. However, experimental protocols typically cancel this factor by using cyclic or constant conditions, limiting the study of environmental variations.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.

Integrating ecological feedbacks across scales and levels of organization
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Macrophytes as biological indicators of organic pollution in the Lepenci River Basin in Kosovo
Macrophytes represent one part of the biological quality elements defined by the European Water Framework Directive (WFD) as ‘macrophytes and phytobenthos’.
