Citation and Reference system in Russia

Hello,

I was curious to know if the citation and reference system is also similar as APA or other system? What might be the systems in Russian academia? Can APA be used normally or the universities have the specific guidelines? Learnerktm 07:48, 28 April 2022 (UTC)

The Russian Federation has a standard for bibliographic descriptions, ГОСТ Р 7.0.100—2018, based on the International Standard Bibliographic Description. (Source: Russian Wikipedia, article section Библиографическое описание § Национальный стандарт Российской Федерации.) I have not attempted to examine how this compares to the APA reference style guide.  --Lambiam 13:03, 28 April 2022 (UTC)

Plants/Animals more affected by Global *cooling*

On our earth, the Polar Bear species is more affected by Global Warming than the Grizzly Bear, but that doesn't mean that the reverse would necessarily be true on an alternate earth that has had as much rapid Global Cooling as we have had Global Warming. What animals would be likely to be negatively affected by a similar Global Cooling than we have. For example, it is possible (but I'm not sure) that equivalent Global Cooling would lead to enough freezes in Florida to cause Florida Crocodile to be extinct in Florida (while remaining in the Caribbean and the norther coast of South America. I'm not sure which animals would be most likely to go extinct in that sort of situation. (if you need specific situation for global cooling, repeated Krakatoa level explosions as necessary spread across both Northern and Southern Hemispheres.Naraht (talk) 12:55, 28 April 2022 (UTC)

you may want to look up literature on the extinctions linked to the Ice ages to obtain more specific data. As a rule of thumb though: 1. smaller mammals spend larger fraction of their energy intake to maintain their body temperature, so are likely to be more affected than larger mammals. 2. species unable to spread or migrate to warmer areas (e.g. due to natural obstacles) are more vulnerable. Hope this helps. Dr Dima (talk) 16:20, 28 April 2022 (UTC)

to add, you need to also be aware that smaller mammals (especially rodents) are more adaptable, and adapt faster, than larger mammals. That is due to the small mammals reaching reproductive age faster, and having larger litters, compared to larger mammals; see R/K_selection_theory. Dr Dima (talk) 16:33, 28 April 2022 (UTC)

Which of the two size-related opposite effects will dominate depends on the speed with which disaster strikes.  --Lambiam 19:40, 29 April 2022 (UTC)

In global warming, species can adapt by migrating towards the poles. Those who are already at the poles (like polar bears) can't, so they are in trouble. In global cooling it would be the reverse: those who are already in the tropics are in trouble. Note that global temperature changes affect the poles more strongly than the tropics, so it wouldn't be as bad for tropical species as global warming is for polar species. Species from mid to high latitudes that can't simply move to lower latitudes because there's a sea in the way (coming from places like New Zealand or Japan) would have a problem too. PiusImpavidus (talk) 08:42, 29 April 2022 (UTC)

So it seems like the example of a species that would be most affected by Global cooling would be is if an Elephant species was in an isolated population in Northern Madagascar. Naraht (talk) 15:00, 2 May 2022 (UTC)

If this is supposed to be a justification for saying "it could be worse. Calm down":

• Turning a jungle into a desert will obviously kill off tons of species.
• The climate change we are forcing on the Earth at the moment does not just consist of global warming - the climate is also becoming more unstable. More hurricanes, more deluges, more draughts.
• In addition to warming the planet, CO2 also makes the oceans more acidic, killing coral reefs.
• Nature is more complex than you think. Species die out for reasons that are not immediately obvious. --Hob Gadling (talk) 15:12, 2 May 2022 (UTC)
