Control experiments marked in green. Figure S2. Relative germination rate in percentage of Adansonia digitata seeds after digestion of elephants and exposed to heat for 5 min. Observation time: 10 weeks (W). Control experiments marked in green. Figure S3. Relative germination rate in percentage of Adansonia digitata seeds exposed to heat for 5 min. Observation time: 10 weeks (W). Control experiments marked in green. Figure S4. Relative germination rate in percentage of Adansonia digitata seeds exposed to heat for 40 min. Observation time: 10 weeks (W). Control experiments marked in green.
