Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans [PDF]

open access: yes, 2017
The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws supports an inclusion in Gnathifera nested in the Spiralia.

Specific immune priming in the invasive ctenophore Mnemiopsis leidyi [PDF]

open access: yes, 2013
Specific immune priming enables an induced immune response upon repeated pathogen encounter. As a functional analogue to vertebrate immune memory, such adaptive plasticity has been described, for instance, in insects and crustaceans. However, towards the

Global coordination and standardisation in marine biodiversity through the World Register of Marine Species (WoRMS) and related databases [PDF]

open access: yes, 2013
The World Register of Marine Species is an over 90% complete open-access inventory of all marine species names. Here we illustrate the scale of the problems with species names, synonyms, and their classification, and describe how WoRMS publishes online ...

The mitochondrial genome of the hexactinellid sponge : Evidence for programmed translational frameshifting [PDF]

open access: yes, 2008
Background Mitochondrial genomes (mtDNA) of numerous sponges have been sequenced as part of an ongoing effort to resolve the class-level phylogeny of the Porifera, as well as to place the various lower metazoan groups on the animal-kingdom tree.

Profiling G protein-coupled receptors of Fasciola hepatica identifies orphan rhodopsins unique to phylum Platyhelminthes [PDF]

open access: yes, 2017
G protein-coupled receptors (GPCRs) are established drug targets. Despite their considerable appeal as targets for next-generation anthelmintics, poor understanding of their diversity and function in parasitic helminths has thwarted progress towards GPCR-

Approaches to the ethology of hydroids and medusae (Cnidaria, Hydrozoa) [PDF]

open access: yes, 2000
The behavioural patterns of 26 species of Antho- and Leptomedusae (with or without medusa stage) were investigated by video recordings. The analysed activities were: answers to mechanical stimuli, prey capture and ingestion, digestion, egestion, and ...

Coral Disease and Health Workshop: Coral Histopathology II [PDF]

open access: yes, 2007
The health and continued existence of coral reef ecosystems are threatened by an increasing array of environmental and anthropogenic impacts. Coral disease is one of the prominent causes of increased mortality among reefs globally, particularly in the ...

Social Feeding Behavior of Trichoplax adhaerens

open access: yesFrontiers in Ecology and Evolution, 2019
Animals have evolved different foraging strategies in which some animals forage independently and others forage in groups. The evolution of social feeding does not necessarily require cooperation, social feeding can be a beneficial individual-level ...

The Opisthokonta and the Ecdysozoa may be clades: An update on Philip et al. (2005) [PDF]

open access: yes, 2009
To test the monophyly of Opisthokonta (animal-fungal clade) and Ecdysozoa (nematode-arthropod clade), Philip et al [Mol. Biol. Evol. 22: 1175–1184 (2005)] used sequence data from 10 eukaryotic genomes (an alveolate, a plant, two ascomycetous ...
