An analysis of ethanol-induced behavioural plasticity in Caenorhabditis elegans
… targets<br/>integrate to produce various behavioural responses remains far from clear.<br/><br/>The nematode worm Caenorhabditis elegans is a model genetic organism with a<br/>simple nervous system and well-defined behaviour. These nematodes can display<br/>plasticity in the form of …

Individual risk and reward in the wild. A study on blue tits
Behavioural biologists seek to understand why individuals of the same species differ in their behaviour. The "pace-of-life syndrome" (POLS) hypothesis offers a framework to explain such individual behavioural variation. It puts forth that individuals differ broadly in how they take risks in their …

Mating costs and gametic barriers to reproduction
… behaviours and performance. I find evidence for behavioural plasticity in males influenced by mate search duration to maximize female egg laying which may be mediated by male seminal fluids and/or female cryptic choice. I then use transparent organisms, Caenorhabditis nematodes, to identify a …

Behavioural Ecology of Large Tuna
… for stressor impacts. However, understanding behavioural responses requires monitoring at temporal resolutions matching the biological processes of interest, from sub-second events to seasonal strategies. Accelerometers uniquely capture behaviour across this breadth: high-frequency sampling …

Hide and seek : a multidisciplinary study on the ecological success of an estuarine dweller
… role in the estuarine food web. Here, I applied behavioural experiments using a novel method to quantify pigment cover (PiC) to study background matching in Crangon crangon, and assessed the application of metabarcoding to define its trophic ecology in six European estuaries. Results indicate …

The effects of flooding disturbance on the distribution and behaviour of riparian arthropods along a lowland gravel river
… are expected to have evolved or adjusted their behavioural responses in accordance with their functional life-history characteristics such as habitat affinity and mobility. Correspondingly, less mobile species are expected to show variation in their spatial genetic structure as well. Based on an …

Evaluation of anthropogenic disturbance on African clawless otter (Aonyx capensis) physiological stress, behaviour, and population density using non-invasive methods
… Conversely, the otters exhibit substantial behavioural plasticity to exploit the anthropogenic landscape. Transformed areas such as Millstream farm provide ACOs with suitable habitat and abundant food resources, evidently supporting higher than average otter population densities. Such …

Sentinel behaviour and urban environments: A corvid’s perspective
… urbanized species such as the American crow can behaviourally adapt to exploit anthropogenic resources resulting in positive urbanization effects on corvids. While individual-level behavioural adaptations are an active area of research, social behaviour adaptations and their contribution to the …

The ecology of a recovering native predator: the European pine marten (Martes martes)
… fluctuations, and in denning as observed through behavioural plasticity in response to scarcity of natural above ground sites. Finally, I provide robust evidence of a three-way interaction between a recovering native predator, the pine marten, an invasive alien species, they grey squirrel, and a …
