The web is such an essential part of a spider’s life that some researchers consider it an extension of the animal’s consciousness.
White-tailed deer jump in front of cars in November and the number of crashes increases.
According to a recent US study, the transition to winter time significantly increases deer crashes in the US. According to an article in Current Biology, there were 16% more crashes.
In total, there are approximately two million accidents between cars and deer in the United States each year. If the clocks were not moved, according to the researchers’ calculations, 33,000 deer and 33 human lives would be saved every year.
Why this happens is due to a couple of factors. With the change of clocks, the rhythm of commuting traffic changes and there are more cars in motion at dusk. Then the deer are already on the move.
The second point is biological. The rut season of deer falls in November, when deer bucks in particular are active hosts, as can be concluded from the main video of this story.
The problem was particularly acute on the US East Coast.
– Autumn has a really sharp spike, says Prugh from the University of Washington in Seattle.
In the western states, growth can also be seen, but it is not nearly as steep.
– On the east coast, the change of autumn falls in the middle of the white-tailed deer’s mating season. In addition to the fact that motorists are more active after dark, there are also more deer. The timing couldn’t be worse, Prugh states in the New Scientist publication.
The white-tailed deer, or more recently the white-tailed deer, has become so abundant in Finland that its population is now estimated to be over a hundred thousand animals.
In the provincial accident statistics, animals collide with cars the most in Varsinais-Suomi and Uusimaa. Of course, the deer density area also falls in Etelä Häme, for example Vesilahti.
Varsinais-Suomi is a good comparison province because there are white-tailed deer in the whole province. The statistics do not strongly support the transition to winter time affecting the number of accidents, as deer accidents always happen the most in November.
This year’s data is still missing, but last year in Finland proper there were 85 deer crashes a week before the clocks were changed and 75 after (257 and 249 in the whole country). In 2020, the numbers would again show a clear effect: crashes in the week before the change of clocks 52 and after the change 63 (in the whole country in 2020: 169 and 213).
The annual variation is large, as in 2019 the figures were 61 and 66 (the whole country: 232 and 208), while in 2018 they were 51 and 60 (the whole country: 149 and 182). If you add up the above-mentioned years, then in the week after the transition to winter time, the growth in Finland proper will be 6 percent and in the whole country 5.6 percent.
Kim Väisänen, chairman of the board of think tank Libera, would find something to cut at least in home care support and entertainment cruises.
Finland is getting into more debt all the time, and next year new debt will be taken on at eight billion euros. In Tuesday’s A-studio, financial experts will discuss how to balance the Finnish economy.
– In my opinion, docking between Stockholm and Helsinki or Stockholm and Turku during people’s free time should not be supported, Väisänen said.
– We have a large ecological crisis, which involves climate change, loss of nature, overuse of natural resources. Then we have an energy crisis coming on badly in the winter and we also have some kind of healthcare crisis and the population is getting older, Ahokas listed.
He pointed out that all difficult social challenges should be dealt with at the same time and public finances should be looked at from that perspective.
In the opinion of Kim Väisänen of Ajatuspaja Libera, the Finnish economy has not moved forward in 14 years. He compared Finland to a water runner.
– Finland has been water running for 14 years now. Unlike the water runner, we have not moved forward. We have stayed put. That’s the biggest problem, Väisänen thought in Tuesday’s A-studio.
– If that period were cut out, then our situation would actually be quite good, Maliranta reflected.

Does the left hand know what the right hand is doing? This comparison came up as a cause for concern on Monday, when the city of Vaasa organized a public meeting about the plans to clear Gerby’s nearby forest and build apartments instead.
The future plans of the city of Vaasa for one of the central nearby forests of Gerby’s residential area have already aroused the opposition of almost 1,600 people. The new Gerby rinne – residential area planned by the city of Vaasa is being zoned in the middle of the forest, which is used for active and versatile recreational use by the local residents.
Over the decades, the area has become an important neighborhood forest for many people, where people go for both exercise and relaxation. This project, when realized, would bring up to 300 new residents to the forest in apartment, terraced and single-family houses.
The address opposing the project has collected so many names that the city reacted to it by organizing an open public meeting about the project. The event was held at the Gerby Swedish-language school in Vaasa on Monday.
Not all the tables and chairs in the dining room were enough when people wanted to express their concerns about the city’s plans. The new site plan area would be 13 hectares in size and 4.3 hectares would be built on it.
The fish and plant growing system aquaponics makes it possible to grow food at home. If you lower the price for the work, then growing food at home is not economically viable, because the system requires regular maintenance.
How would it sound to raise your own rainbow trout at home? It would be possible with the help of the rotational cultivation system, which has already been used in food production in the ancient Aztec Empire.
Aquaponics refers to a system where a pump transports the water in the aquarium through a biofilter to the plants that utilize the excrement of the fish. The water cleaned of nutrients is transferred back to be used by the fish.
There are completely ready-made circular growing systems for consumers, but it is also possible to build aquaponics yourself. However, rotational farming requires a lot of maintenance. Because of the hours of work involved, growing fish and vegetables using aquaponics at home is not economically viable.
Instead, it’s a fun hobby that allows you to produce local food and observe the ecosystem up close.
– In that case, the small group should carefully calculate the return according to the annual fish catch, because it can be more difficult to earn a profit from salads and vegetables.
However, if you optimize the equipment for vegetables instead of fish, more profit can be accumulated from vegetables, adds Pulkkinen.
– If, for example, fish costs €15–20/kg in the store and the device produces 5–10 kg of vegetables at the same rate, then at current prices, cucumber and tomato are placed in the \”same box\” with fish.
However, with a small amount of feed, you can get a lot of food for the whole group. For example, one kilogram of feed produces one kilogram of fish and up to ten kilograms of vegetables, reveals Pulkkinen.
Legislation does not set obstacles for small-scale fish farming with an aquaponics system.
– You could grow up to 2,000 kilos of fish a year without an environmental permit. Catches larger than this already require a permit, explains Pulkkinen.
The need for an environmental permit would hardly be a problem for a small group wanting food from aquaponics. The housing company might more likely want to produce a few tens or hundreds of kilos of fish a year, Pulkkinen thinks.
It would be particularly important to pay attention to where the water would be brought into the selected system and where the exit water would end up, reminds Pulkkinen.
