摘要: Climate change directly affects arctic-alpine plants and acute responses to increased temperatures may be seen in their reproductive fitness germination ability. However, uncertainties prevail predicting whether a future warmer climate favors or hampers seed high latitude altitude soils research such systems has not been able provide generalizable patterns of response. The available literature on this subject conducted at various locations contributing difficulties the response seeds change. Here, we show that discrepancies collection, dormancy breaking treatments, conditions found published are possible reasons for our inability draw large scale conclusions. We explore how these factors influence results highlight fact many previous investigations have reported effects temperature, rather than all associated complex environmental interactions, germination. recommend long-term monitoring treatments mimic present alpine is likely produce more ecologically meaningful insights suggest several practical steps researchers can take would facilitate greater coherence between studies.
