1. From wolf to dog: Behavioural evolution during domestication
Sammanfattning : Biologists since Darwin have recognized that domestication, where species are selected to live in human-controlled environments, exerts strong selection on organisms and dramatically impacts their evolutionary trajectories. Across domesticated mammal species, characteristic morphological, physiological and behavioural changes occur simultaneously, as correlated traits, a phenomenon known as the domestication syndrome.

2. Evolution of Mimicry and Aposematism Explained: Salient Traits and Predator Psychology
Sammanfattning : Aposematic species have evolved conspicuous warning signals, such as bright colors and striking patterns, to deter predators. Some edible and harmless species take advantage of this deterrent effect by mimicking their appearance. Mimicry is a great example of how natural selection produces remarkable adaptations. LÄS MER
3. Evolutionary and mechanistic aspects of insect host plant preference
Sammanfattning : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.

4. Predator psychology and mimicry evolution - a theoretical analysis
Sammanfattning : The evolution of Müllerian mimicry depends on many factors, among which predator psychology is the most important one. Predator avoidance learning, generalization and discrimination are primary selective agents during the evolutionary process. LÄS MER
5. Behavioural, physiological and morphological correlates of life-history in killifishes − a macroevolutionary approach
Sammanfattning : Life-histories commonly evolve along a continuum from short-lived and fecund, to long-lived and less fecund. Because life-history traits are mostly components of reproduction and survival, understanding the causes and consequences of life-history variation is at the core of evolutionary biology. LÄS MER
