Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

Pest Management Science, EarlyView.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Molecular parallelisms between pigmentation in the avian iris and the integument of ectothermic vertebrates.

PLoS Genetics, 2021
Birds exhibit striking variation in eye color that arises from interactions between specialized pigment cells named chromatophores. The types of chromatophores present in the avian iris are lacking from the integument of birds or mammals, but are ...

Effect of cadmium chloride on general body colouration and chromatophores of stinging cat fish, Heteropneustes fossilis (Bloch) [PDF]

, 2018
Chromatophores, specialized pigment cells in poikilothermic animals, have shown great potential in their use as a cell-based biosensor in the detection of a broad range of environmental toxicants, as structure and number of chromatophores alters ...

Morphological and molecular evidence reveals a new species of Characidium from the Ucayali‐Urubamba Piedmont, Peru, and novel molecular clades are proposed within the genus

Journal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...

A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

Interplay between excitation kinetics and reaction-center dynamics in purple bacteria

, 2010
Photosynthesis is arguably the fundamental process of Life, since it enables energy from the Sun to enter the food-chain on Earth. It is a remarkable non-equilibrium process in which photons are converted to many-body excitations which traverse a complex
