Отправлено: 08.05.22 05:37. Заголовок: Doubts and Questions about the Project

I have a doubt that I think doesn't fit in any of the existing topics, so I decided to make one to ask it. This can also help other english speaking members to ask theirs in the future.

By the way:I was reading the chapter Freshwater sea of Asia and saw this phrase in the description of the Baikal hard-beaked dolphin: "Only a few species of dolphin survived from the entire Order."
Does it means that beyond the Baikal one, another dolphin could have survived in freshwater?
I'm really curious with this possibility. By the way, it's an excellent chapter. Made me remember of a documentary about the wildlife of Russia that I watched in 2018.

OK, the topic is reasonable.

I have a doubt

Which doubt?

цитата:

Only a few species of dolphin survived from the entire Order.

This is mentioned once more in the following text:

цитата:

the order is represented by only a few species with a very limited range

This second mentioning suggests the presence of other species, yes. But where?

The "Neocene: the portrait of the Earth" mentions a descendant of the finless porpoise living in China. Does it already have a description?
Also, would be possible for at least another relic cetacean live in the Amazon river? Maybe a descendant of the Genus Sotalia, these animals can enter in rivers. This could be the only other species of cetacean in the world.

Doubtful. But I guess the Author could tell.

May be. Depends on the exact location. Some may already have such predators, but some may not.

I was thinking about Japan, the chapter about the island is still in Russian, so I don’t know if it already exist, or any other large carnivore.
Other descriptions that I could are for the smaller and arboreal descendants of the common raccoon that live in Europe and are also mentioned in the "Neocene: the portrait of the Earth".

If you mean the chapter 93 "Green Poisoner and Its Suite", it has no carnivores. But Bestiary may contain some Japanese species as well.

I searched in the Bestiary and only found the description of squirrels of Honshu Island. Maybe there is more in the Russian part, because in the picture of one of these rodents, there is some type of feline in the background.

Yes, you are right!

In Japan we have Japan aglah - large marine bentophagous predator - descendant of the raccoon dog (Nyctereutes procyonoides)
http://sivatherium.narod.ru/mammals.htm#thalassocanis_nipponicus_ru

Also we have Kama-itachi - medium-sized ground-dwelling predator - descendant of Japanese weasel (Mustela itatsi)
http://sivatherium.narod.ru/mammals.htm#tardomustela_nipponica_ru

and there is an animal that has not yet been accepted:
Bakeneko - large predator hunting both in the trees and on the ground - descendant of domestic cat

And I almost forget about red berl - medium-sized land predator http://sivatherium.narod.ru/2gisiber.htm#quasiursus_rufus_en

Would make sense if there is at least another hypercarnivore in Japan? For example, a descendant of a marten or of the domestic dog. Or perhaps a panda-like descendants of the raccoon-dog that is more herbivore than carnivore.
While I was reading about Japan, I thought about a genus of a nectar eating rodent that I also eats soft fruits.

Hardly so. Wovoka wrote that there are one weasel and one canine predator in the area in question, so the niches are occupied (and they are not so numerous due to the area limitation - it is an island, remember?).

цитата:

Sounds interesting, but raccoon dog is quite rare today and unlikely to give two descendants simultaneously.

Yes, but rather than being capable of glide, it would be an acrobatic species, moving fast through the canopy with a semi-prehensile tail. Due to winter in Japan, I think that it could also hibernate.

Such animal can exist only in conditions of the year-round presence of blossoming nectar-bearing species. It means - not in conditions of seasonal climate, because in winter flowers do not eager to blossom, as I know.

True, but the Honey possum of Australia also only eats nectar and pollen, but the flowers aren’t present all time of the year in the part of Australia where they live. So they enter in torpor when there isn't enough food. Then, this species of rodent could have this same strategy, or also be omnivorous. During the blossoming period, it eat mostly nectar of the flowers. When autumn arrives, it start to eat fruits and insects. In the end of the autumn, this animal hibernates through winter.

True.

цитата:

But note that feeding on nectar and on fruits and especially insects may require different structures of teeth, tongue and maybe even jaws, let alone different (to certain degree) digestive systems (the difference would concern mostly enzymes, and anatomy to lesser degree).

Yes. This is why I was re-thinking this animal. In this case, they would not be like the honey possum, but more like the sugar glider, with a seasonally adaptive omnivorous diet. For example, in spring they would feed on pollen and nectar, in summer they would also eat insects, in autumn there will be fruits and sap. When winter arrives, they hibernate or enter in torpor.
