Species interactions (CLIM 026) - Assessment published Nov 2012
Climate change (Primary topic)
Typology: Descriptive indicator (Type A - What is happening to the environment and to humans?)
- CLIM 026
Key policy question: How is climate change affecting food networks and other species interactions, and what are the implications for biodiversity?
- Climate change is affecting the interaction of species that depend on each other for food or other reasons. It can disrupt established interactions but also generate novel ones.
- Negative effects on single species are often amplified by changes in interactions with other species, in particular for specialist species.
- The impact of species interactions on ecosystems services depends on whether disrupted interactions can be buffered by system-intrinsic properties or by novel organisms.
Projected spatial mismatches of the Portuguese Dappled White butterfly and its host plants
Note: This figure shows spatial mismatches of the Portuguese Dappled White butterfly (Euchloe tagis) and its host plants under the BAMBU scenario (climate: A2) for 2050-2080. Green, suitable climate space for the host plants;orange, suitable climate space for the butterfly; red, suitable area for both butterfly and host plants; open circles, currently observed distribution. BAMBU: Business-As-Might-Be-Usual scenario.

Direct observations of the effects of recent climate change on competition are scarce and are generally thought not to have led directly to the extinction of species in Europe [i]. However, independent studies have shown that observed changes in the distribution and abundance of Populus species (a group of trees that are relatively weak competitors) in the Late Glacial (ca. 13 000–10 000 years ago) and in the 20th century could only be explained when the effects of climate change on its competitors were taken into account [ii].
Climate change has already lead to temporal mismatches between species that depend on each other for feeding and for pollination. For example, the egg hatch of the winter moth (Operophtera brumata) has advanced more than the budburst date of its larval food plant, the pedunculate oak (Quercus robur), over the past two decades, with potentially severe consequences for its fitness [iii]. Similarly, over the last 30 years, the occurrence of the honey bee (Apis mellifera) and the Small White butterfly (Pieris rapae) in relation to the flowering of crucial host plants has changed from about 10 days and 5 days later to about 25 days and 15 days earlier, respectively [iv]. Such temporal mismatches can severely impact pollination activities and the seed set of plants [v]. Climate change has also disrupted several predator-prey relationships, such as between insectivorous birds and their insect prey [vi]. In some cases, differential changes in phenology can also strengthen existing or create new predator-prey relationships, as observed by an increased predation pressure of the fat dormouse (Glis glis) on several songbirds in the Czech Republic [vii].
Climate change can also generate new interactions in novel communities [viii]. In extreme cases, this can lead to severely transformed ecosystems where new species dominate. Such changes are particularly obvious at higher latitudes and altitudes, where growing and reproductive periods are prolonged or where previous thermal constraints are released with climate warming. For instance, the range of the pine processionary moth (Thaumetopoea pityocampa) is no longer limited by temperature in many regions, enabling the species to expand its existing range into new areas and causing serious damage in pine forests [ix].
A study on butterflies in Europe showed that most species are not limited by the distribution of their larval host plants and thus appear rather insensitive to spatial mismatching with their hosts under future climate change. However, there are exceptions such as the Portuguese Dappled White butterfly (Euchloe tagis), which is projected to lose 20–48 % of its current area based on the loss of suitable climatic conditions by 2080, and 50–74 % when a reduced availability of host plants was also considered (Figure 1) [x]. These findings highlight the need for a better understanding of ecological interactions that mediate species responses to climate change.
