Estimating Dispersal Kernels for Stream Periphyton Using Drifting Lake Algae [PDF]
Ecology and EvolutionDispersal patterns are a key component of many ecological and evolutionary processes, yet they remain understudied in microbial species due to technical challenges.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state. [PDF]
J Anim EcolThe pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

The Role of Local and Upstream Colonisation in Determining Stream Periphyton Metacommunity Assemblages [PDF]
Ecology and EvolutionStream periphyton is an ideal study system for explaining how dispersal shapes community patterns. Few studies have tried to investigate periphyton metacommunities at the reach scale, and studies comparing local versus upstream periphyton propagule ...

Denitrification Associated with Periphyton Communities [PDF]
Applied and Environmental Microbiology, 1981 Scrapings of decomposing Cladophora sp. mats (periphyton) covering stream bed rocks produced N 2 O when incubated under N 2 plus 15% C 2 H 2 . Denitrification (N 2 O formation) was enhanced by NO

Frontiers in Microbiology, 2021 The conversion of mercury (Hg) to monomethylmercury (MMHg) is a critical area of concern in global Hg cycling. Periphyton biofilms may harbor significant amounts of MMHg but little is known about the Hg-methylating potential of the periphyton microbiome.
