Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics

Journal of Phycology, EarlyView.
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

Journal of Phycology, EarlyView.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

Heat stress induces organelle alterations in Macrocystis pyrifera gametophytes

Journal of Phycology, EarlyView.
Abstract Kelp, brown macroalgae in the order Laminariales, provide ecosystem services vital to ocean biodiversity. However, kelp forests worldwide are declining due to abiotic stressors such as ocean warming. In this study, we present results from high‐resolution confocal microscopy and in vivo imaging system imaging using protocols developed to ...

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Identification and functional analysis of class 3 lipases associated with triacylglycerol metabolism in Nannochloropsis oceanica (Eustigmatophyceae)

Journal of Phycology, EarlyView.
Abstract Microalgae accumulate triacylglycerols (TAGs) as storage lipids in response to nutrient limitation, yet the mechanisms governing TAG turnover remain incompletely understood. In the oleaginous microalga Nannochloropsis oceanica, functional studies of TAG degradation have focused on lipases containing patatin domains, whereas the roles of other ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Top-down Control of Algal Biomass: The Role of Snails (Elimia Potosiensis) in the James River Watershed, Missouri

, 2007
Algal biomass in streams is influenced by a combination of bottom-up (nutrients) and top-down (gazers) effects. The objective of the current study was to investigate the relationship between snails and algal biomass through a survey and an in situ ...

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, EarlyView.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.
