Marine Biodiversity Records, 2011 Here we report on intraspecific cleaning behaviour between two adult bluestreak cleaner wrasse Labroides dimidiatus of similar size on coral reefs surrounding Lizard Island, Great Barrier Reef, Australia. During a SCUBA dive, we observed these individuals posing and the resulting cleaning interactions. While aggression in this species is common between

Ecology and Evolution, Volume 16, Issue 1, January 2026.This study shows that young goats outperform sheep in the reversed‐reward contingency task, which is a cognitive test requiring both inhibitory control and cognitive flexibility. The results highlight the importance of cognitive flexibility when solving this type of task, and suggest that the differences between both species may reflect social and ...

Pairs of cleaner fish prolong interaction duration with client reef fish by increasing service quality [PDF]
, 2017 We present field experiments showing that levels of cooperation quantitatively predict the duration of interactions between the cleaner wrasse and its reef fish clients.

Ecology of Freshwater Fish, Volume 35, Issue 1, January 2026.ABSTRACT Freshwater habitats in the Indo‐Pacific Islands are colonised by amphidromous fish, which undergo a marine larval phase while the rest of the life cycle takes place in the riverine habitat. These fish are mainly represented by Gobiiformes. Among these, Stenogobius genivittatus (Valenciennes, 1837) is widely distributed in the Indo‐Pacific ...

Plasticity of thermal tolerance and associated gill transcriptome in ballan wrasse (Labrus bergylta)
Frontiers in Marine ScienceThermal condition has profound influence on physiology and behaviour of ballan wrasse (Labrus bergylta), a cleaner fish commonly deployed in salmon cages to control sea lice infection.

The ephemeral reward task: Pigeons and rats fail to learn unless discouraged from impulsive choice [PDF]
Animal Behavior and Cognition, 2018 The failure of certain species to learn a particular task while others learn it easily can help identify the learning mechanisms involved. In the ephemeral reward task, animals are given a choice between two distinctive stimuli, A and B, each containing ...

Matching times of leading and following suggest cooperation through direct reciprocity during V-formation flight in ibis [PDF]
, 2015 One conspicuous feature of several larger bird species is their annual migration in V-shaped or echelon formation. When birds are flying in these formations, energy savings can be achieved by using the aerodynamic up-wash produced by the preceding bird ...

Shifting Harbor Seal (Phoca vitulina) Diet May Reflect Ecosystem Changes in Skagerrak
Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Harbor seals, as generalist predators, can adjust their diet in response to shifts in prey availability; thus, their diet composition has the potential to act as a biodiversity indicator. This study examined the diet of harbor seals in the Skagerrak by analyzing otoliths from scat samples collected in 2020 and compared species composition to ...

To clean or not to clean: Cleaning mutualism breakdown in a tidal environment
Ecology and Evolution, 2020 The dynamics and prevalence of mutualistic interactions, which are responsible for the maintenance and structuring of all ecological communities, are vulnerable to changes in abiotic and biotic environmental conditions.
