From individuals to ecosystems – the broader consequences of climate change on phenology
Session ID#: 85149
Session Description:
The effects of climate change on phenology - the timing of annual recurring biological events - are well known. Such studies usually tend to expect âearlier when warmerâ outcomes. However, biological patterns are not solely influenced by temperature, and the interacting effects of other physical, biological and anthropogenic variables (e.g. sea ice, stratification, hypoxia, predator-prey dynamics, fisheries) are often ignored. Moreover, studies typically focus on single taxa and/or single trophic levels, whereas the wider ecosystem effects of climate-driven changes in phenology are poorly known. In this session, we will highlight studies that 1. move beyond single taxa and climatic variables, towards those that investigate the effects of climate-driven phenology at the population level and beyond; and 2. focus on the wider implications of phenological changes on productivity, ecosystem structure, function, and the socio-economic system.
We encourage contributions on:
- Impacts of phenological change on predator-prey interactions, higher trophic levels, fitness, productivity, ecosystem structure and function.
- Effects of more than one explanatory variable (e.g. temperature and sea ice) or interacting effects
- Regional or broader impacts of phenological change
- New approaches to detect climate effects on phenology
- Socio-economic consequences of phenological change
