Phylogenetic relationships and the timing of evolutionary events are essential for understanding evolution on longer time scales. Cheilostome bryozoans a group ubiquitous, species-rich, marine colonial organisms with an excellent fossil record but lack phylogenetic inferred from molecular data. We present genome-skimmed data 395 cheilostomes combine these 315 published sequences to infer key among c. 500 cheilostome species. find that named genera species phylogenetically coherent, rendering...
Abstract Climate change can alter ecological communities both directly, by driving shifts in species distributions and abundances, indirectly influencing the strength direction of interactions. Within benthic marine ecosystems, foundation such as canopy‐forming macro‐algae often underpin important cascades facilitative We examined wider impacts climate‐driven relative abundances within a temperate reef system, with particular focus on habitat cascade whereby kelp facilitate epiphytic algae...
Kelp species are ecologically-important habitat-formers in coastal marine ecosystems, where they alter environmental conditions and promote local biodiversity by providing complex biogenic habitat for an array of associated organisms. While it is widely accepted that kelps harbour significant biodiversity, our current understanding spatiotemporal variability kelp-associated assemblages the key drivers patterns remains limited. Here we examined influence ocean temperature wave exposure on...
Lichens are exemplar symbioses based upon carbon exchange between photobionts and their mycobiont hosts. Historically considered a two-way relationship, some lichen have been shown to contain multiple photobiont partners; however, the way in which these communities react environmental change is poorly understood. Lichina pygmaea marine cyanolichen that inhabits rocky seashores where it submerged seawater during every tidal cycle. Recent work has indicated L. complex community including...
Parental care is considered crucial for the enhanced survival of offspring and evolutionary success many metazoan groups. Most bryozoans incubate their young in brood chambers or intracoelomically. Based on drastic morphological differences incubation across members order Cheilostomatida (class Gymnolaemata), multiple origins were predicted this group. This hypothesis was tested by constructing a molecular phylogeny based mitogenome data nuclear rRNA genes 18S 28S with most complete sampling...
Abstract Cheilostomata is the most diverse and ecologically dominant order of bryozoans living today. We apply a Bayesian framework to estimate macroevolutionary rates cheilostomes since Late Jurassic across four datasets: (I) manually curated genus ranges; (II) published text‐mined (III) non‐revised Paleobiology Database (PBDB) records; (IV) revised augmented PBDB records. All datasets revealed increased origination in Albian, twin K–Pg Danian extinction rate peak. High Selandian–Ypresian...
Polyembryony–the production of multiple cloned embryos from a single fertilised egg–is seemingly paradoxical combination reproductive modes that nevertheless persists in diverse taxa. We document features polyembryony the Cyclostomata (Bryozoa)–an ancient order modular colonial marine invertebrates–that suggest substantial reduction nature this enigmatic mode. Firstly, we provide molecular evidence for three exemplar species, supporting widely cited inference characterises entire order....
Abstract Animal mitogenomes are typically devoid of introns. Here, we report the largest number mitochondrial introns ever recorded from bilaterian animals. Mitochondrial were identified for first time phylum Bryozoa. They found in four species three families (Order Cheilostomatida). A total eight complete mitogenome Exechonella vieirai , and five, 17 18 partial Parantropora penelope Discoporella cookae Cupuladria biporosa respectively. Intron-encoded protein domains reverse transcriptase...
Many sessile, suspension-feeding marine invertebrates mate by spermcasting: aquatic sperm are spawned and gathered conspecific individuals to fertilize eggs that generally retained during development. In two phylogenetically distant examples, a cheilostome bryozoan an aplousobranch ascidian, the receipt of allosperm has previously been shown alter sex allocation triggering female investment in brooding. Here we report experiments demonstrating species cyclostome also show restrained absence...
Cyclostomes are the only order of stenolaemate bryozoans living today. The non-feeding larvae modern cyclostomes metamorphose on settlement to produce a calcified dome-shaped protoecium. Protoecial diameter provides proxy for larval size. sparse data available suggests that protoecial is about one-and-a-half times greater than width. Here we use estimate sizes in fossil and Recent cyclostome species. A total 233 protoecia were measured, 143 from 90 cyclostomes, which 84 came Jurassic. ranged...
Cyclostomes are an ancient order of bryozoans with more than 500 living species. Traditionally, cyclostome taxonomy has depended almost entirely on characters the calcareous skeletons mature colonies. However, taxonomic distribution these is largely incongruent well-supported molecular phylogenetic trees, implying need for major revisions if to reflect phylogeny. While far taxa must be sequenced ascertain their relationships, there also a discover morphological that can used support clades,...
<title>Abstract</title> The main aim of this study was to investigate whether environmental or biological factors predominantly influence bryozoan mineralization along the South African coast (spanning from 29.263°S; 16.87°E 27.540°S; 32.677°E), a region known for its diverse oceanographic conditions. New data into mineralogical (calcite vs. aragonite) and geochemical (Mg content in calcite) composition bryozoans are provided thereby enhancing global database understanding biomineralization...

Version 1.5 Purpose: This SOP outlines the method used to DNA barcode macroalgae and marine protists (microalgae), fungi lichens for DToL project. The barcodes will be generated allmacroalgae protists, being collected by orcultivated at MBA (as a Genome Acquisition Lab – GAL) sent Sangerfor sequencing. Barcodes act as markers track final genomes back tooriginal samples, verify morphological identifications. Summary As part of Darwin Tree Life(DToL) initiative, is tasked with barcoding all...
