Natural sounds have always called me. As an Echo and electro-actics researcher with a background in sound engineering and electronic music composition, I have always tried to strike a balance between art and science in my work.
In 1998, when I first heard about the extinction crisis – over 35,500 species of flora and fauna are endangered – the idea for the extinction project came to me very quickly. My vision was to create a collection of ’24-hour-long frag acoustic fractions’ that were recorded in the highest definition, capturing the sonic heritage of ancient, biodiversified, untouched tropical rainforests – before climate change rendered them irreversible. Harms from.
In these forests, some species are vocalized from the canopy, some from the ground and others from the twigs of large trees that act like sound weavers. To capture a 3D acoustic picture of the forest, we simultaneously record over 38 audio channels and microphones.
In this photo, I stand in Sonosfera, a Geodesic theater in Pesaro, Italy, in which viewers can experience the rainforest sounds captured in the Amazon, Africa and Borneo. Twenty-five high-definition loudspeakers are located in a separate, acoustically perfect location, realistically reproducing the natural sounds of the ecosystem.
For the first 15 minutes of the performance, Sonosfer is completely dark. The sound helps the listeners to construct the forest space around them – the position of every insect and amphibian; Birds and mammals through the canopy. My team then presents the spectrograms shown here to interpret the sounds, and current data show that these ecosystems are disappearing.

We have captured deep intrusive calls of elephants and recorded insects that sound like violins or trumps. Our ecosystem recordings are very different. But I have no favorites – they are a collection.
Liz is from Scotland. He has been on a holiday visa working in Canada for almost 2 years and loves every minute in British Columbia, especially the incredible West Coast. With a background in ecology, Liz came to Canada to explore her ecosystem and wildlife, as well as the rich history and culture.
Last summer, Liz traveled from Victoria to Haida Gawai on the coast before spending the winter in Kudayi. Liz has completely fallen in love with Vancouver Island and will be sad to leave in a few weeks. She has been an important part of our volunteer team this year, supporting the FOCS “SUmmer Presentations” and the “Clayoquot Salmon Festival”.
Liz is eager to take home all the amazing things she has learned here and knows that without a doubt she will return to these magical lands. “Thank you so much for the FOCS, you are all wonderful people and have enjoyed learning and knowing you a lot.”
There are over 3,000 species of cicadas, which fall into about two categories: annual cicadas, which are spotted every year, and periodic cicads, which spend the majority of their lives underground and only once a decade or two. Only emerges.
The Cicadas are famous for their penchant for disappearing completely for many years, only to reappear in force at a regular interval. Despite their name, annual cicadas typically live for two to five years – although some species can live longer – and their brood life cycles overlap, meaning that every summer, some cicadas hatch. Huh.
There are also periodic cicadas occurring in different geographic areas from time to time, as they are divided into 15 brood cycles, each lasting 13 or 17 years.
The amazing lifestyle of the cicadas has been a source of attraction since ancient times. Many cultures considered these insects to be powerful symbols of rebirth due to their unusual life cycles.
In early Chinese folklore, cicada was also considered a high-status creature that rulers should imitate in its sanctity, and cicada motifs were also incorporated into the wardrobes of the royal court in the seventh century.
Geographical boundary
While annual cicadas can be found worldwide, the periodic are unique to North America. Periodic brews are concentrated in the central and eastern regions of the United States, and some regions are home to many brews.
Life Cycle
There are three stages of the cicada life cycle: eggs, nymphs and adults. The female cicada can divide 400 eggs into dozens of sites – usually in twigs and branches. After six to 10 weeks, young cicada nymphs grow out of their eggs and dig themselves into the ground to suck up the fluid from the roots of the plant. They spend their entire development time in these underground bridges before they are ready to melt their shells and lay and lay eggs for adults.
