Identifying potential keystone microbes from co-occurrence networks in the Gulf of Alaska
The Northern Gulf of Alaska (NGA) is a highly productive and diverse marine ecosystem. Differences in nutrient supply and physical circulation between nearshore and offshore waters in the NGA result in a mosaic of water masses with distinct ...

ABSTRACT High‐quality reference genome assemblies have become essential for deepening our understanding of biodiversity, yet obtaining them for many species remains surprisingly challenging. Drawing on experiences from the European Reference Genome Atlas (ERGA) community, we focus on permit and sample‐handling procedures leading up to nucleic acid ...

Functional kleptoplasty in a limapontioidean genus: phylogeny, food preferences and photosynthesis inCostasiella, with a focus onC. ocellifera(Gastropoda: Sacoglossa) [PDF]
The evolution and origin of functional kleptoplasty (sequestration and retention of functional plastids) within the Sacoglossa is still controversial. While some authors have suggested that it is a synapomorphy of the parapodia-bearing Plakobranchoidea, others have suggested an earlier origin at the base of the more inclusive clade Plakobranchacea. The

ABSTRACT Benthic Foraminifera exhibit diverse adaptations to low oxygen (O2) environments, including denitrification, a rare trait among eukaryotes. Denitrifying species store intracellular nitrate (NO3−), possibly within vacuoles, and contribute significantly to the global marine nitrogen (N) cycle.

Preliminary Study of Kleptoplasty in Foraminifera of South Carolina [PDF]
Recent studies of living foraminifera, microscopic aquatic protists, indicate that some species have the ability to steal photosynthetic plastids from other microorganism and keep them viable through a process called kleptoplasty.

Abstract As chloroplast‐stealing or “kleptoplastidic” lineages become more reliant on stolen machinery, they also tend to become more specialized on the prey from which they acquire this machinery. For example, the ciliate Mesodinium rubrum obtains > 95% of its carbon from photosynthesis, and specializes on plastids from the Teleaulax clade of ...

Abstract Dinophysis is an obligate mixotroph that relies on consumption of the ciliate, Mesodinium rubrum, to grow and form harmful algal blooms (HABs). In this study, blooms of Dinophysis acuminata in two NY, USA, estuaries were studied over the course of 3 yr (2019–2021) using discrete samples and an Imaging FlowCytobot (IFCB) to capture images of ...

Photoprotective Non-photochemical Quenching Does Not Prevent Kleptoplasts From Net Photoinactivation
The enigmatic association of photosynthetically active chloroplasts from algae and some sacoglossan sea slugs, called functional kleptoplasty, is a functional unique system of photosymbioses observed in metazoans.

Temporal and spatial diversity and abundance of cryptophytes in San Diego coastal waters
Abstract Cryptophytes (class Cryptophyceae) are bi‐flagellated eukaryotic protists with mixed nutritional modes and cosmopolitan distribution in aquatic environments. Despite their ubiquitous presence, their molecular diversity is understudied in coastal waters.

The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling
