Stimpson, 1857, a barnacle predator, is one of the most common and conspicuous intertidal nemerteans found along West Coast North America from Alaska to California, but it currently referred by wrong name. Briefly described without designation type material or illustrations, species was synonymized with Atlantic look-alike,
Green roofs are a way for cities to mitigate environmental stressors, such as heatwaves and droughts. However, these stressors can adversely affect green roof vegetation, causing challenges plant growth survival subsequently reducing the ability of systems deliver critical ecosystem services heat mitigation nutrient cycling. Plant-associated microbes may facilitate resilience tolerance vegetation climate-associated stress. despite their crucial role in natural ecosystems, there has been...
Animals vary widely in their ability to regenerate, suggesting that regenerative has a rich evolutionary history. However, our understanding of this history remains limited because only been evaluated tiny fraction species. Available comparative regeneration studies have identified losses ability, yet clear documentation gains is lacking. We assessed regenerate heads and tails either through own experiments or from literature reports for 35 species Nemertea spanning the diversity phylum,...
Abstract Cell surface properties can strongly mediate microbial interactions with predators in soil and host‐pathogen systems. Yet, the role of avoiding or enhancing predation ocean is less well known. Appendicularians are globally abundant marine suspension feeders that capture microorganisms a complex mucous filtration system. We used artificial microspheres to test whether prey particles influenced selection by appendicularian, Oikopleura dioica . range microsphere sizes (0.5, 1, 2, 3 μ...
Micrura alaskensis Coe, 1901 is a common intertidal heteronemertean known from eastern and northwest Pacific (Alaska to Ensenada, Mexico Akkeshi, Japan, respectively). It an emerging model system in developmental biology research. We present evidence morphology of the adults, gametes, sequences cytochrome c oxidase subunit I 16S rRNA genes that it not one, but complex five, cryptic species. All five these species co-occur at least part their geographic range (e.g. southern Oregon)....
Planktonic organisms feed while suspended in water using various hydrodynamic pumping strategies. Appendicularians are a unique group of plankton that use their tail to pump over mucous mesh filters concentrate food particles. As ubiquitous and often abundant members planktonic ecosystems, they play major role oceanic webs. Yet, we lack complete understanding the fluid flow underpins filtration. Using high-speed, high-resolution video micro particle image velocimetry, describe kinematics...
Abstract A typical nemertean pilidium larva resembles a hat with ear flaps. But one type, called recurvatum , looks more like sock, swimming heel first. This distinctive was discovered in 1883 off the coast of Rhode Island and subsequently found plankton samples from other parts world. Despite long time since discovery, its significance discussions larval evolution, this remained unidentified even to family level. We collected larvae Coos Bay, OR identified them as belonging heteronemertean...
Biodiversity assessments are critical for setting conservation priorities, understanding ecosystem function and establishing a baseline to monitor change. Surveys of marine biodiversity that rely almost entirely on sampling adult organisms underestimate diversity because they tend be limited habitat types individuals can easily surveyed. Many animals have planktonic larvae sampled from the water column at shallow depths. This life stage often is overlooked in surveys but used relatively...
Ribbon worms (phylum Nemertea) are among several animal groups that have been overlooked in past studies of genome-size diversity. Here, we report estimates for eight species nemerteans, including representatives the major lineages phylum. Genome sizes these ranged more than fivefold, and there was some indication a positive relationship with body size. Somatic endopolyploidy also appears to be common animals. Importantly, this study demonstrates both most methods estimation (flow cytometry...
The genus Carinina Hubrecht, 1885 has long been considered the most ‘archaic’ nemertean taxon because its members are distinguished by basiepidermal position of brain and lateral nerve cords, characters thought to be plesiomorphic for phylum. Here we describe two new species, yushini sp. nov. from Sea Japan (Russia) C. chocolata north-east Pacific (Oregon, USA), brown body colour. A phylogenetic analysis based on partial sequences five nuclear mitochondrial gene regions, 18S rRNA, 28S...
Unique to the phylum Nemertea, pilidium is an unmistakable planktonic larva found in one group of nemerteans, Pilidiophora. Inside pilidium, juvenile develops from a series epidermal invaginations larval body, called imaginal discs. The discs grow and fuse around gut over course weeks months plankton. Once complete, breaks free body catastrophic metamorphosis, often devours as its first meal. One third nemertean species are expected produce but larvae known for very few species; development...
Prochlorococcus is the most abundant photosynthetic cell on Earth and critical to primary productivity biogeochemical cycles of open ocean. Appendicularians are ubiquitous gelatinous filter-feeding zooplankton that feed marine microorganisms including . However, details this feeding interaction extremely understudied relative its potential importance in top-down controls This first study experimentally examine several dimensions between cultivated appendicularians Prochlorococcus. We found...
The purpose of this application, under Articles 23.9.3, 41, 65.2, and 70.2 the Code, is to conserve current usage year priority name Emplectonematidae Bürger, 1904 for a family ribbon worms by reversing its precedence with respect senior synonym, Eunemertidae Joubin, 1894, concept type genus, Emplectonema Stimpson, 1857, designating viride 1857 as species. In preparation these rulings, common species, Nemertes gracilis Johnston, 1837, designated herein nominal genera 1837 (a largely...
Abstract Animals vary widely in their ability to regenerate, suggesting that regenerative abilities have a rich evolutionary history.

Available comparative studies identified losses ability, yet clear documentation gains is lacking. We surveyed 34 species spanning the phylum Nemertea, assessing regenerate heads and tails either through own experiments or from...
