Nice research and great to see Poznan featured: it is a great town if you get a chance to visit. Just don't drink vodka with the locals, they're nutters. Some

Nice research and great to see Poznan featured: it is a great town if you get a chance to visit. Just don't drink vodka with the locals, they're nutters. Some seeds I am pretty amazed by are some of those of the cycads. Check these out: https://i.pinimg.com/474x/3f/35/ca/3f35ca3dbdfbaf957ad6ca333c8e6965--seeds.jpg https://i.pinimg.com/474x/3f/35/ca/3f35ca3dbdfbaf957ad6ca333... They both have spikes and are physically quite large and hard, so large and hard in fact that nothing alive can eat them. Apparently a going theory is that they previously largely depended upon distribution by extinct macro-fauna. I wonder: does that mean the groves that we find in the Australian bush date from periods of macro-fauna? Anthropogenic distribution is limited to 65,000 years, water can move seed, yet many are in places for which water cannot account for seed dispersal. What a shame that we are destroying and mismanaging everything for short term need through ignorance.
