Insights into the early gonad development of the protogynous ballan wrasse (Labrus bergylta)

open access: yesAquaculture Reports, 2023
The reproductive biology of ballan wrasse, a popular cleaner fish species now bred in captivity, is not well understood particularly the early stages of development and their accompanying endocrine changes. The protogynous nature of this species has been

Fine‐scale environmentally associated spatial structure of lumpfish (Cyclopterus lumpus) across the Northwest Atlantic

open access: yesEvolutionary Applications, 2023
Lumpfish, Cyclopterus lumpus, have historically been harvested throughout Atlantic Canada and are increasingly in demand as a solution to controlling sea lice in Atlantic salmon farms—a process which involves both the domestication and the transfer of ...

The Guppy Effect as Interference [PDF]

open access: yes, 2012
People use conjunctions and disjunctions of concepts in ways that violate the rules of classical logic, such as the law of compositionality. Specifically, they overextend conjunctions of concepts, a phenomenon referred to as the Guppy Effect. We build on

Cleaner fishLabroides dimidiatusmanipulate client reef fish by providing tactile stimulation [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2001
The cleaner wrasse Labroides dimidiatus often touches 'client' reef fish dorsal fin areas with its pelvic and pectoral fins. The relative spatial positions of cleaner and client remain constant and the cleaner's head points away from the client's body. Therefore, this behaviour is not compatible with foraging and the removal of client ectoparasites. As

Colour change and assortment in the western rainbowfish [PDF]

open access: yes, 2010
Grouping behaviour is widespread across the animal kingdom, and is known to reduce an individual's risk of predation, for example through predator confusion.

Parasite distribution on client reef fish determines cleaner fish foraging patterns [PDF]

open access: yesMarine Ecology Progress Series, 2002
Recent evidence suggests that cleaner fish Labroides dimidiatus effectively control parasite densities on client reef fish that actively visit them to have parasites and dead or infected tissue removed. These findings support the hypothesis that clients benefit from cleaning, However, they do not show how cleaners reduce the parasite load of their ...

A Cross-Sectional Survey on Knowledge and Perceptions of Health Risks Associated with Arsenic and Mercury Contamination from Artisanal Gold mining in Tanzania. [PDF]

open access: yes, 2013
An estimated 0.5 to 1.5 million informal miners, of whom 30-50% are women, rely on artisanal mining for their livelihood in Tanzania. Mercury, used in the processing gold ore, and arsenic, which is a constituent of some ores, are common occupational ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Cleaner fish cause predators to reduce aggression toward bystanders at cleaning stations [PDF]

open access: yes, 2017
Mutualisms, in which both participants gain a net benefit, are ubiquitous in all ecosystems, and the importance of understanding their broader ecological context has been demonstrated many times.
