A detailed description of the development of the hemichordate Saccoglossus kowalevskii using SEM, TEM, Histology and 3D-reconstructions.

Frontiers in zoology

Kaul-Strehlow S, Stach T.
PMID: 24010725
Front Zool. 2013 Sep 06;10(1):53. doi: 10.1186/1742-9994-10-53.

INTRODUCTION: Traditionally, the origin of the third germ layer and its special formation of coelomic cavities by enterocoely is regarded to be an informative character in phylogenetic analyses. In early deuterostomes such as sea urchins, the mesoderm forms through...

Diversity, environmental requirements, and biogeography of bivalve wood-borers (Teredinidae) in European coastal waters.

Frontiers in zoology

Borges LM, Merckelbach LM, Sampaio I, Cragg SM.
PMID: 24520913
Front Zool. 2014 Feb 13;11(1):13. doi: 10.1186/1742-9994-11-13.

BACKGROUND: Bivalve teredinids inflict great destruction to wooden maritime structures. Yet no comprehensive study was ever carried out on these organisms in European coastal waters. Thus, the aims of this study were to: investigate the diversity of teredinids in...

Host response to cuckoo song is predicted by the future risk of brood parasitism.

Frontiers in zoology

Kleindorfer S, Evans C, Colombelli-Négrel D, Robertson J, Griggio M, Hoi H.
PMID: 23692969
Front Zool. 2013 May 22;10(1):30. doi: 10.1186/1742-9994-10-30.

INTRODUCTION: Risk assessment occurs over different temporal and spatial scales and is selected for when individuals show an adaptive response to a threat. Here, we test if birds respond to the threat of brood parasitism using the acoustical cues...

Young male mating success is associated with sperm number but not with male sex pheromone titres.

Frontiers in zoology

Kehl T, Dublon IA, Fischer K.
PMID: 26557870
Front Zool. 2015 Nov 09;12:31. doi: 10.1186/s12983-015-0124-y. eCollection 2015.

BACKGROUND: Intraspecific communication is of crucial importance throughout the animal kingdom and may involve a combination of visual, gustatory, olfactory and acoustic cues. Variation in male sex pheromone amount and composition may convey important information to female conspecifics, for...

Comparative localization of serotonin-like immunoreactive cells in Thaliacea informs tunicate phylogeny.

Frontiers in zoology

Valero-Gracia A, Marino R, Crocetta F, Nittoli V, Tiozzo S, Sordino P.
PMID: 27708681
Front Zool. 2016 Sep 29;13:45. doi: 10.1186/s12983-016-0177-6. eCollection 2016.

BACKGROUND: Thaliaceans is one of the understudied classes of the phylum Tunicata. In particular, their phylogenetic relationships remain an issue of debate. The overall pattern of serotonin (5-HT) distribution is an excellent biochemical trait to interpret internal relationships at...

The Snark was a Boojum - reloaded.

Frontiers in zoology

Macrì S, Richter SH.
PMID: 26816519
Front Zool. 2015 Aug 24;12:S20. doi: 10.1186/1742-9994-12-S1-S20. eCollection 2015.

In this article, we refer to an original opinion paper written by Prof. Frank Beach in 1950 ("The Snark was a Boojum"). In his manuscript, Beach explicitly criticised the field of comparative psychology because of the disparity between the...

Feeding cessation alters host morphology and bacterial communities in the ascidian Pseudodistoma crucigaster.

Frontiers in zoology

López-Legentil S, Turon X, Erwin PM.
PMID: 26770257
Front Zool. 2016 Jan 14;13:2. doi: 10.1186/s12983-016-0134-4. eCollection 2016.

BACKGROUND: Ascidians can associate with abundant and diverse consortia of microbial symbionts, yet these communities remain unexamined for the majority of host ascidians and little is known about host-symbiont interactions.METHODS: We coupled electron microscopy and 16S rRNA gene tag...

Integrating resource defence theory with a neural nonapeptide pathway to explain territory-based mating systems.

Frontiers in zoology

Oldfield RG, Harris RM, Hofmann HA.
PMID: 26813803
Front Zool. 2015 Aug 24;12:S16. doi: 10.1186/1742-9994-12-S1-S16. eCollection 2015.

The ultimate-level factors that drive the evolution of mating systems have been well studied, but an evolutionarily conserved neural mechanism involved in shaping behaviour and social organization across species has remained elusive. Here, we review studies that have investigated...

Visualization of the 3D structures of small organisms via LED-SIM.

Frontiers in zoology

Ruan Y, Dan D, Zhang M, Bai M, Lei M, Yao B, Yang X.
PMID: 27303437
Front Zool. 2016 Jun 14;13:26. doi: 10.1186/s12983-016-0158-9. eCollection 2016.

BACKGROUND: Innovative new techniques that aid in the visualization of microscopic anatomical structures have improved our understanding of organismal biology significantly. It is often challenging to observe internal 3D structures, despite the use of techniques such as confocal laser...

Differences in neurochemical profiles of two gadid species under ocean warming and acidification.

Frontiers in zoology

Schmidt M, Windisch HS, Ludwichowski KU, Seegert SLL, Pörtner HO, Storch D, Bock C.
PMID: 29093740
Front Zool. 2017 Oct 30;14:49. doi: 10.1186/s12983-017-0238-5. eCollection 2017.

BACKGROUND: Exposure to future ocean acidification scenarios may alter the behaviour of marine teleosts through interference with neuroreceptor functioning. So far, most studies investigated effects of ocean acidification on the behaviour of fish, either isolated or in combination with...

Odonata (dragonflies and damselflies) as a bridge between ecology and evolutionary genomics.

Frontiers in zoology

Bybee S, Córdoba-Aguilar A, Duryea MC, Futahashi R, Hansson B, Lorenzo-Carballa MO, Schilder R, Stoks R, Suvorov A, Svensson EI, Swaegers J, Takahashi Y, Watts PC, Wellenreuther M.

Odonata (dragonflies and damselflies) present an unparalleled insect model to integrate evolutionary genomics with ecology for the study of insect evolution. Key features of Odonata include their ancient phylogenetic position, extensive phenotypic and ecological diversity, several unique evolutionary innovations,...

Mandible evolution in the Scarabaeinae (Coleoptera: Scarabaeidae) and adaptations to coprophagous habits.
