Giant phytoplankton revealed by in situ imaging
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate

Comparative single-cell genomics of two uncultivated Naegleria species harboring Legionella cobionts
Amoeboflagellates of the genus Naegleria are free-living protists ubiquitously found in soil and freshwater habitats worldwide. They include the “brain-eating amoeba” Naegleria fowleri, an opportunistic pathogen that causes primary amoebic ...

Mitochondrial Genome Reduction and Accelerated Evolution in Planktonic Foraminiferans
The mitochondrial genomes of the eukaryotic lineage Retaria (Foraminifera and Radiolaria) show reductions in multiple gene categories, including complex I, transfer RNAs (tRNAs), ribosomal proteins, and ribosomal RNAs. In planktonic foraminifera, this reduction is even more pronounced, with the potential loss of atp and other genes.

Geographic Variability of Fish Carcass–Associated Microbial Communities
When sardine carcasses (A) were deployed across seven Japanese tidal flats (B), both bacterial (D) and ciliophoran assemblages (C) varied substantially among sites. Yet, carcass‐associated shifts (blue) were overshadowed by regional variation (red), indicating that local species pools and environmental conditions—rather than carcass inputs alone ...

Bacterial domain fusion drives biomineralization innovation in Colepidae ciliates
Mineralized external structures have evolved independently across unicellular eukaryotes. Within the phylum Ciliophora, this trait’s restriction to the family Colepidae makes it an ideal model for dissecting the genomic basis of this innovation. Here, we

The entanglement between the IUCN Red List and international biodiversity law
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species (red list) is of fundamental importance for nature conservation and biodiversity protection. I considered the interaction between the red list and international biodiversity law (IBL), the legal regime that aims to protect biodiversity at a global level ...

Three genotypes – a heat‐resistant maize (Zea mays), a heat‐susceptible maize, and a sorghum (Sorghum bicolor) variety – were grown to the V4 stage in growth chambers under optimal conditions or subjected to heat stress. Plants were grown in soil containing a complex microbial community, or in the same soil with a depleted microbiome.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Despite textbook definitions of foraminifera as marine organisms, foraminifera also occur in freshwater habitats, with first reports from ~150 years ago.
