No way back: decadal lack of functional recovery of a coralligenous community in a warming Mediterranean

Oikos, EarlyView.
Anthropogenic disturbances are degrading nature at a rate that exceeds its capacity to recover. While considerable research has focused on understanding ecosystem impacts, recovery processes remain comparatively overlooked, particularly in marine ecosystems, where long‐term data on how highly complex systems respond to disturbances are scarce.

Challenging Host Specificity: Malacosporean Parasite Dynamics—Tetracapsuloides bryosalmonae Beyond Salmonids—An Infection Experiment

Journal of Fish Diseases, EarlyView.
ABSTRACT Proliferative Kidney Disease (PKD) is a severe parasitic disease of salmonids caused by the malacosporean endoparasite Tetracapsuloides bryosalmonae. In the fish intermediate host, the parasite is disseminated via the circulatory system and ultimately reaches the kidney, where it matures before releasing infective spores into the environment ...

Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
Background Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities.

Exceptionally preserved jellyfishes from the Middle Cambrian. [PDF]

PLoS ONE, 2007
Cnidarians represent an early diverging animal group and thus insight into their origin and diversification is key to understanding metazoan evolution.

Histopathological and Molecular Data on Myxobolus spp. Infecting Bryconid Fish From the Brazilian Pantanal Wetland

Journal of Fish Diseases, EarlyView.
ABSTRACT Previous studies described Myxobolus umidus infecting the spleen of Brycon hilarii, whereas Myxobolus pantanalis and Myxobolus salminus infecting the gill filaments of Salminus brasiliensis. In this study, we provided supplementary morphological and molecular data on these three Myxobolus species and histopathological analyses of the tissues ...

Phylogenomics provides a robust topology of the major cnidarian lineages and insights on the origins of key organismal traits

BMC Evolutionary Biology, 2018
Background The phylogeny of Cnidaria has been a source of debate for decades, during which nearly all-possible relationships among the major lineages have been proposed.

Origins of neurogenesis, a cnidarian view

Developmental Biology, 2009
New perspectives on the origin of neurogenesis emerged with the identification of genes encoding post-synaptic proteins as well as many "neurogenic" regulators as the NK, Six, Pax, bHLH proteins in the Demosponge genome, a species that might differentiate sensory cells but no neurons.

Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

Cnidarians and Their Polychaete Symbionts [PDF]

, 2016
Cnidarians, especially skeleton-bearing anthozoans and hydrocorals, are known to host abundant and diverse symbiotic fauna encompassing members of the majority of metazoan taxa, ranging from sponges and flat worms to fishes. Members of the class Polychaeta are between the most diverse and perhaps the least studied taxa of coral symbionts.
