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.

Molecular assessment of heterotrophy and prey digestion in zooxanthellate cnidarians [PDF]
Zooxanthellate cnidarians are trophically complex, relying on both autotrophy and heterotrophy. Although several aspects of heterotrophy have been studied in these organisms, information linking prey capture with digestion is still missing.

A review of cnidarians and ctenophores feeding on competitors in the plankton [PDF]
, 1991 Predation among pelagic cnidarians and ctenophores is reviewed. The diets of semaeostome scyphomedusae and hydromedusae commonly include other gelatinous zooplanktivores.

Impact of El Niño-Southern Oscillation 2015-2016 on the soluble proteomic profile and cytolytic activity of Millepora alcicornis (“fire coral”) from the Mexican Caribbean [PDF]
PeerJ, 2019 Reef-forming cnidarians are extremely susceptible to the “bleaching” phenomenon caused by global warming. The effect of elevated seawater temperature has been extensively studied on Anthozoans; however, to date the impact of thermal stress on the ...

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 ...

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 ...

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 ...

Expulsion of symbiotic algae during feeding by the green hydra--a mechanism for regulating symbiont density? [PDF]
PLoS ONE, 2008 Algal-cnidarian symbiosis is one of the main factors contributing to the success of cnidarians, and is crucial for the maintenance of coral reefs. While loss of the symbionts (such as in coral bleaching) may cause the death of the cnidarian host, over ...

Mesophotic octocoral larval settlement preferences and behaviors
Restoration Ecology, EarlyView.Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...
