Hooked on zombie worms? Genetic blueprints of bristle formation in Osedax japonicus (Annelida)
BackgroundThis study sheds light on the genetic blueprints of chaetogenesis (bristle formation), a complex biomineralization process essential not...

Current State of Planktonic and Benthic Communities in the Mouth Part of the Northern Dvina River
AbstractThe Northern Dvina River, one of the largest watercourses in the European northeast of Russia, is exposed to a multifactorial anthropogenic...

Sources of variation in endohelminth parasitism of common eiders over-wintering in the Canadian Arctic
Documenting how climate change will affect Arctic ecosystems and food web dynamics requires an understanding of current sources of variation in...

Cellular proliferation dynamics during regeneration in Syllis malaquini (Syllidae, Annelida)
BackgroundIn syllids (Annelida, Syllidae), the regenerative blastema was subject of many studies in the mid and late XX th century. This work on...

Myogenesis of Siboglinum fiordicum sheds light on body regionalisation in beard worms (Siboglinidae, Annelida)
BackgroundMany annelids, including well-studied species such as Platynereis , show similar structured segments along their body axis (homonomous...

Studying Annelida Regeneration Using Platynereis dumerilii
Regeneration, the ability to restore body parts after an injury or an amputation, is a widespread property in the animal kingdom. This chapter...

Spezielle Zoologie Teil B: Bilateria – Prostostomia
Protostomia (Urmünder) stellen eine Großgruppe der Bilateria dar. Die Gruppe wird dadurch definiert, dass der Urmund (Blastoporus) sich zum...

Microbiomes of microscopic marine invertebrates do not reveal signatures of phylosymbiosis
Animals and microorganisms often establish close ecological relationships. However, much of our knowledge about animal microbiomes comes from two...

Distribution and biodiversity patterns of hyperiid amphipods across the coastal-offshore gradient of the sub-tropical Southeast Pacific
The subtropical region of the Southeast Pacific exhibits a strong onshore-offshore gradient in hydrographic conditions and biological production from...

Conservative route to genome compaction in a miniature annelid
The causes and consequences of genome reduction in animals are unclear because our understanding of this process mostly relies on lineages with often...

Fine structure of the cerebral eyes in Flabelligera affinis (Annelida, Sedentaria, Cirratuliformia): new data prove the existence of typical converse annelid multicellular eyes in a sedentary polychaete
Sedentary polychaetes usually possess small and simple eyes with flabelligerids being an exception by possessing large pigmented eyes. These eyes...

The anatomy and development of the nervous system in Magelonidae (Annelida) – insights into the evolution of the annelid brain
BackgroundThe annelid anterior central nervous system is often described to consist of a dorsal prostomial brain, consisting of several commissures...

Sri Lankan Mangroves: Biodiversity, Livelihoods, and Conservation
Mangroves in Sri Lanka occur in a patchy distribution along the island’s coastline, in areas adjacent to lagoons, estuaries, and river mouths...

Spectral responses across a dorsal–ventral array of dermal sensilla in the medicinal leech
How do animals use visual systems to extract specific features of a visual scene and respond appropriately? The medicinal leech, Hirudo verbana , is a...

Development and structure of the anterior nervous system and sense organs in the holopelagic annelid Tomopteris spp. (Phyllodocida, Errantia)
Tomopteridae are transparent, predatory Annelida inhabiting pelagic ocean zones. Despite being well-known for their fast metachronal swimming and...

Recent progress in reconstructing lophotrochozoan (spiralian) phylogeny
Lophotrochozoa (also called Spiralia), the sister taxon of Ecdysozoa, includes animal taxa with disparate body plans such as the segmented annelids,...

Detailed morphology of tentacular apparatus and central nervous system in Owenia borealis (Annelida, Oweniidae)
The Oweniidae are marine annelids with many unusual features of organ system, development, morphology, and ultrastructure. Together with magelonids,...

Uses of nonhuman primates by humans in northeastern Brazil
Humans have used non-human primates (hereafter referred to as primates) as food source, medicine, parts of rituals, pets, and models for various...

Sluggish methane discharge and biological traits of benthic invertebrates in Lake Baikal
The biological traits of invertebrates inhabiting freshwater methane seeps are poorly understood. We analysed the relationship between invertebrate...

Regeneration in Annelids: Cell Sources, Tissue Remodeling, and Differential Gene Expression
AbstractRecent studies have shown that, despite stereotypical cleavage, annelids show the ability for embryonic regulation, including the formation...
