Expert‐Based Prioritization of Control Measures for Salmonid Rickettsial Septicemia in Chilean Salmon Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsiosis (SRS) remains the main infectious disease affecting salmon aquaculture in Chile. This study evaluated expert perceptions of the effectiveness of SRS control measures and the level of agreement among industry professionals.

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

Journal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Earlier spring may explain dominance of the slow‐growing dinoflagellate Naiadinium polonicum over the cyanobacterium Microcystis during a heatwave

Journal of Phycology, EarlyView.
Abstract Global warming and extreme weather events have been linked to a rise in cyanobacterial blooms, which threaten water quality and ecosystem services. However, during an extreme hot and dry summer, Microcystis was outcompeted by a dinoflagellate, Naiadinium polonicum, in a drinking water lake in southern Sweden.

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Journal of Phycology, EarlyView.
Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate new hypotheses for the interpretation of metagenomic data and enrich ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Surface darkening by abundant and diverse algae on an Antarctic ice cap

Nature Communications
Algal blooms play important roles in physical and biological processes on glacial surfaces. Despite this, their occurrence and impacts within an Antarctic context remain understudied.

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Cosmopolitan and endemic species jointly enhance the potential of producing algal blooms in Tibetan glaciers

Communications Earth & Environment
Snow algal blooms lead to glacier and snow surface albedo reduction and subsequent melting. To explore snow algal distribution patterns and potential to cause blooms, we investigated snow algae in the Tibetan, Antarctic, Arctic, and Alps.

Evolution‐Inspired Engineering of Diterpene Biosynthesis via Chloroplast Genome Modification

Plant Biotechnology Journal, EarlyView.
ABSTRACT Terpenes constitute the largest and most structurally diverse class of plant secondary metabolites, with critical roles in plant‐environment interactions and broad industrial applications. Although nuclear genome engineering of terpene pathways has been extensively explored, chloroplast genome engineering remains largely undeveloped, with most
