1. Stress and the Offspring : Adaptive Transgenerational Effects of Unpredictability on Behaviour and Gene Expression in Chickens (Gallus gallus)
Abstract : Environmental stress has shown to affect both the exposed individuals and the development of their offspring. Generally, it is thought that the stressed organism responds to stress by trying to adapt to it. READ MORE

2. The Xenopus tropicalis model for developmental endocrine and reproductive toxicity : Histological and molecular endpoints for disrupted spermatogenesis
Abstract : Endocrine disrupting chemicals (EDCs) are linked to adverse effects in both humans and wildlife. There are however, large knowledge gaps regarding cause-effect and dose-response relationships between the interference with endocrine pathways and adverse effects in the organism, especially at puberty and in subsequent generations.

3. Dynamics of the aphid-ant mutualism
Abstract : An appreciation of the role of mutualism is essential when studying ecology and evolution in most ecosystems. Information covering aspects of mutualistic interactions can serve as a complement to the somewhat one-sided perspective from the 1950’s and 60’s that is used when teaching biology. READ MORE

4. Phenotypic Plasticity and Adaptation Potential to Salinity in Early Life Stages of the Tunicate, Ciona intestinalis spB
Abstract : Species respond to environmental heterogeneity through a variety of mechanisms such as plasticity, genetic adaptation and phenotypic buffering. Determining how gene flow, scale of environmental heterogeneity and trait heritability influence these responses is important for understanding how these different mechanisms arise, which is a central task in the field of evolutionary biology.

5. Fishy behavior : persistent effects of early-life exposure to 17α-ethinylestradiol
Abstract : The synthetic estrogen 17α-ethinylestradiol (EE2) is an endocrine disrupting chemical (EDC) of concern due to its persistent nature and widespread presence in the aquatic environment. In mammals, effects of developmental EDC exposure on reproduction and behavior not only persist to adulthood after discontinued exposure, but are also inherited by several consecutive unexposed generations.
