Climate change (Primary topic)
Typology: Descriptive indicator (Type A - What is happening to the environment and to humans?)
- CLIM 025
Key policy question: How is climate change affecting the seasonal cycle of animals in Europe?
- Many animal groups have advanced their life-cycles in recent decades, including frogs spawning, birds nesting and the arrival of migrant birds and butterflies. This advancement is attributed primarily to a warming climate.
- The breeding season of many thermophilic insects (such as butterflies, dragonflies and bark beetles) has been lengthening, allowing more generations to be produced per year.
- The observed trends are expected to continue in the future but quantitative projections are rather uncertain.

Several studies have convincingly demonstrated a tight dependency of life-cycle traits of animals with ambient temperatures, both in terrestrial and aquatic habitats[i]. Mostly, the observed warming leads to an advanced timing of life history events. For example, temporal trends for appearance dates of two insect species (honey bee, small white: Pieris rapae) in more than 1 000 localities in Spain have closely followed variations in recorded spring temperatures between 1952 and 2004 [ii].
The predicted egg-laying date for the Pied flycatcher (Ficedula hypoleuca) showed significant advancement between 1980 and 2004 in western and central Europe, but delays in northern Europe, both depending on regional temperature trends in the relevant season (see Figure 1) [iii]. Data from four monitoring stations in south to mid-Norway that include nest-boxes of Pied flycatcher from 1992–2011 show in contrary to the regional temperature estimated trends that there are no significant delays in egg-laying date for the Pied flycatcher, but an annual fluctuation making a rather flat curve for the median over these years [iv]. A study in the Netherlands covering the period between 1932 and 2004 found that half of the investigated bird species are now overwintering significantly closer to their breeding site than in the past, most likely due to warmer winters [v]. A long-term trend analysis of 110 common breeding birds across Europe (1980–2005, 20 countries) showed that species with the lowest thermal maxima showed the sharpest declining trends in abundance[vi]. In other words, cold-adapted species are losing territory most quickly.
A study from the UK found that each of the 44 species of butterfly investigated advanced its date of first appearance since 1976 [vii]. Recent studies on birds, butterflies and amphibians not only confirmed previous findings that there is a coherent fingerprint of climate change in the pattern of phenological changes [viii], but also indicated that average rates of phenological change have recently accelerated in line with accelerated warming trends [ix]. There is also increasing evidence about climate-induced changes in spring and autumn migration, including formerly migratory bird species becoming resident [x].
Projections for animal phenology are rarely carried out, except for species of high economic interest[xi]. Quantitative projections are hampered by the high natural variability in phenological data, particularly in insects[xii]. The projected future warming is expected to cause further shifts in animal phenology and can lead to an increase of trophic mismatching, unforeseeable outbreaks of species, a decrease of specialist species and changes in ecosystem functioning[xiii].
