A dichotomous species of Codium (Bryopsidales, Chlorophyta) is colonizing northern Chile [PDF]

Revista chilena de historia natural, 2004
A fines de 2001 y principio de 2002, aparecio en el norte de Chile una especie del genero Codium, de morfologia dicotomica, colonizando los niveles intermareales y submareales de la Bahia de Caldera (27° 03’ S, 70° 51’ O). Debido al impacto ecologico y economico que ha provocado esta especie en la Bahia de Caldera y a su dispersion potencial a lo largo

Metabarcoding as a tool to examine cryptic algae in the diets of two common grazing surgeonfishes, Acanthurus triostegus and A. nigrofuscus

Environmental DNA, Volume 4, Issue 1, Page 135-146, January 2022., 2022
Abstract Surgeonfishes (Acanthuridae) are an important group of herbivores that are abundant on reefs globally. Acanthurids consume macroalgae that can compete with corals for space, turf algae that can proliferate on degraded reefs, and detritus that may smother adult corals or inhibit settlement.

Quantifying the diet diversity of herbivorous coral reef fishes using systematic review and DNA metabarcoding

Environmental DNA, Volume 4, Issue 1, Page 191-205, January 2022., 2022
In this study we conducted a systematic literature review of quantitative diet studies addressing herbivorous reef fishes in the Pacific to compare diet diversity. We also examined the diets of five common surgeonfish in Hawaiʻi using metabarcoding and compared the findings of the two approaches.

The underexplored potential of green macroalgae in aquaculture

Reviews in Aquaculture, Volume 14, Issue 1, Page 5-26, January 2022., 2022
Abstract Green macroalgae (Chlorophyta) currently represent a residual fraction (<1%) of global seaweed biomass production landings. In turn, red (Rhodophyta) and brown (Ochrophyta) macroalgae dominate the remaining percentage of aquaculture production, exceeding 32 million tonnes per annum.

Insights into the bacterial community composition of farmed Caulerpa lentillifera: A comparison between contrasting health states

MicrobiologyOpen, Volume 10, Issue 6, December 2021., 2021
The co‐occurrence of bacteria in sea grape (green caviar) Caulerpa lentillifera under two health state conditions was studied. The role of potentially detrimental and beneficial bacteria was discussed. A baseline for understanding the C. lentillifera holobiont was presented.

Tubular microfossils from ∼2.8 to 2.7Ga-old lacustrine deposits of South Africa: A sign for early origin of eukaryotes? [PDF]

, 2016
Unequivocal evidence for Archean eukaryotic life has been long sought for and is a matter of lively debate. In the absence of unambiguous fossils this debate has focused on biogeochemical signatures and molecular phylogenies.

Phylogenomic analysis restructures the ulvophyceae

Journal of Phycology, Volume 57, Issue 4, Page 1223-1233, August 2021., 2021
Here, we present new transcriptome sequencing data from seven species of Dasycladales (Ulvophyceae) and a phylogenomic analysis of the Chlorophyta with a particular focus on Ulvophyceae. We have focused on a broad selection of green algal groups and carefully selected genes suitable for reconstructing deep eukaryote evolutionary histories.

How endo- is endo-?: surface sterilization of delicate samples: a Bryopsis (Bryopsidales, Chlorophyta) case study [PDF]

, 2010
In the search for endosymbiotic bacteria, elimination of ectosymbionts is a key point of attention. Commonly, the surface of the host itself or the symbiotic structures are sterilized with aggressive substances such as chlorine or mercury derivatives ...

Morphotype differentiation in the Great Barrier Reef Halimeda bioherm carbonate factory: Internal architecture and surface geomorphometrics

The Depositional Record, Volume 7, Issue 2, Page 176-199, June 2021., 2021
A geomorphometric analysis of Holocene Halimeda bioherms in the northern Great Barrier Reef was undertaken by combining high‐resolution 3D LiDAR bathymetry and 2D sub‐bottom profile datasets. The three bioherm morphotypes (termed annulate, reticulate and undulate) vary significantly in their surface topography, internal structure, volume, slope ...

Permanent residents or temporary lodgers: characterizing intracellular bacterial communities in the siphonous green alga Bryopsis [PDF]

, 2013
The ecological success of giant celled, siphonous green algae in coastal habitats has repeatedly been linked to endophytic bacteria living within the cytoplasm of the hosts.
