Changes were inconsistent with predictions derived from past disturbances (no increase in shade-tolerant or long-lived late-succesional species), rainfall or temperature increase (no increase in evergreen or deciduous species, respectively). Among 27 common tree species, net population growth was negatively correlated with maximum tree size and longevity, and positively correlated with leaf size and leaf nutrient content, especially so when initial population size was controlled for. Increased stem density resulted from enhanced recruitment of understory treelets (Piper tucumanum, Eugenia uniflora, Allophylus edulis) into small size classes. Between 19, stem density markedly increased by 50 % (12 stems ha21 y21) and basal area by 6 % (0.13 m2 ha21 y21). The study relies on 15 years of demographic monitoring within 8 ha of subtropical montane forest in Argentina.
Undisturbed nature drivers#
Here, we report rapid net structural and compositional changes in an old-growth subtropical forest and we assess the functional nature of these changes to test hypothetical drivers including recovery from past disturbances, reduction in ungulate browsing, CO2 fertilization, and increases in rainfall and temperature.
It is my hope that these films will contribute to a deeper understanding and gratitude of the natural wonders in our world and to the preservation of our fragile environment in the future.Recent studies have shown directional changes in old-growth tropical forests, but changes are complex and diverse, and their drivers unclear.
Undisturbed nature series#
Afterwards this footage was combined with lot of creativity to make a series of 4K video films that show the beautiful landscapes of the Nordic countries. The footage was afterwards stabilized in postproduction.ĭuring my hiking in the undisturbed nature I shot 35 thousands time-lapse photos and several hundred aerial photography videos in 4K UHD of some of Scandinavia’s most beautiful spots. To create movement in this timelapse I used a motorized slider. Instead of lying sleepless I went for walks in the nature and came one early morning across this beautiful waterfall at the Geirangerfjord.įrom the Geirangerfjord the road goes very steep to the Dalsnibba mountain plateau in 1476m. It can be a challenge to fall asleep in the bright Norwegian summernights. So with this magnificent scenery in front of me I turned on my camera, put up my tent and stayed for the night.Īt the island Havøya close to the North Cape I was the spectator to one of natures rare phenomena – lenticular clouds. It was while driving along the fjords on this unique route that I came across this spectacular place and felt an urge to stop. This route has everything … if you like bridges, ferries, tunnels and countless eye-catching sights … and if you are not in a hurry. in this permanent state of nature, there is a 'great chain of being' with a place for each creature (a habitat and a niche) and create in its. if it is disturbed and the disturbing force is removed, nature returns to exactly the same permanent state 3.
This clip is made at the coastal route of northern Norway – the Fv17. 1.nature undisturbed achieves a permanency of form and structure that persists indefinitely 2. To my amazement, I saw the biggest ans tallest tree I have ever seen in my life. I was standing outside and looking up into the sky to see if it was cloudy since it was kinda nippy outside. But I think it was worth the effort.Ĭlose to the North Cape I had the opportunity to make a timelapse of a sun halo which is an optical phenomena produced by light interacting with ice crystals in the upper atmosphere. Undisturbed nature: Biggest tree Ive ever seen. To make this clip of dancing morning clouds over a glacier lake, I had to get out of my warm sleeping bag at 3 o’clock in the morning. The first clip is from Svartisen – the second largest glacier in Norway. To get the right shots it was often necessary to hike for hours with heavy equipment to remote locations.ĭescription of timelapses in ‘Undisturbed Nature’: On this epic journey not only the most popular tourist places were visited. This adventure went from Copenhagen in the south of Scandinavia through the always changing landscapes of Norway with its deep fjords, snowy mountains, glaciers and many waterfalls, through the untouched islands of Lofoten and all the way to the moon landscape at the North Cape before returning to Denmark through Finland and Sweden with thousands of lakes and deep mysterious forests. The material for the timelapse film ‘Undisturbed Nature’ was shot during a 7000 km long road trip through amazing scenery in the summer 2016.
