Escherichia Species Diversity Across Pristine and Impacted Catchments: Evidence for Avian Sources of Escherichia marmotae in Aotearoa/New Zealand

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Escherichia spp. were obtained from pristine and impacted environments to define community structure and assess potential human health risks. E. coli was more prevalent from sites affected by livestock or human activities, whereas non‐E. coli Escherichia spp. were more prevalent in avian faeces and native forest with fewer faecal sources.

The Masked Role of Periphyton in Phosphorus Cycling: Mechanistic Insights Under Large‐Scale Hydrologic and Seasonal Variability

Water Resources Research
The role of periphyton in lake phosphorus cycling has long been overlooked or simplified, as water quality models often classify periphyton parameters as non‐sensitive, thereby masking their key roles in phosphorus cycling.

Carbonate sediment production in coastal wetlands: Periphyton contributions and diatom indicators

Ecological Indicators
Coastal ecosystems rapidly transform as sea levels rise faster than ecosystems can build elevation through biological processes that accrete organic matter and inorganic sediment.

Network Component Analysis Can Identify Potential Axenisation Strategies Circumventing Antibiotic‐Use for Phototrophic Eukaryotic Microalgae

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Network component analysis of published axenisation methods reveals optimal, antibiotic‐free workflows for phototrophic eukaryotic microalgae. Distinct strategies are identified for diatoms, dinoflagellates, and green algae. Verification using microscopy, sequencing, and cell counting enhances reproducibility.

Impact of the Highly Invasive Signal Crayfish (Pacifastacus leniusculus) on Freshwater Macroinvertebrate Communities

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Invasive non‐native species threaten freshwater ecosystems, disrupting the functioning and structure of the food chain and potentially leading to biodiversity loss. As omnivores, crayfish can modify their environment, directly affecting organisms such as macroinvertebrates.

Consumption of periphyton and bioseston by Mozambique tilapia in aqua dams with three different substrates

Aquaculture Environment Interactions
Periphyton-based aquaculture can reduce feed input costs. Here we characterised the periphyton and bioseston formation in aqua dams stocked with net, plastic, and stone substrates.

Green Sea Turtle Recruitment in the Eastern North Pacific: Patterns Identified Using Geochemical Signatures in Bones

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We present vital life‐history and demographic data including the oceanic stage duration, timing of ontogenetic habitat shifts, and multi‐year foraging patterns of eastern North Pacific green sea turtles found in Southern California. The findings were obtained by analyzing sea turtle bones (age and growth via skeletochronology; and habitat and diet via ...

Periphyton pigment shifts in lakes with varying water colour: a possible monitoring method for freshwater Browning

Ecological Indicators
Despite several negative effects of browning, there are no sufficient bioindicators to monitor it. In this study, the effects of water quality on the photosynthetic pigment content of periphyton grown on artificial substrata in different depths were ...

Contrasting impacts of warming and browning on periphyton

Limnology and Oceanography Letters, 2023
We tested interactive effects of warming (+2°C) and browning on periphyton accrual and pigment composition when grown on a synthetic substrate (plastic strips) in the euphotic zone of 16 experimental ponds.

Sediment Characteristics in Stonewort Chara tomentosa Assemblages

Ecology and Evolution, Volume 16, Issue 1, January 2026.
The study investigated sediment characteristics associated with Chara tomentosa. The results show that sediment grain size and the concentration of the dissolved phosphate in the porewater differ in the seafloor areas characterised by C. tomentosa from adjacent areas at similar depth, but without charophytes.
