On the crumpled bark, a few neat scratches are engraved on it.

Bi Fang stretched out his hand and pressed on the big tree, grabbing it with his five fingers, and the audience clearly saw that no one could catch such a big scratch with their hands, and the owner of the paw print was definitely a big guy.

【Bear? Bears nearby? 】

[I'll rub, I'll take a look, is Lao Fang the first person to find clues now? 】

[It seems to be]

[Awesome, it's time to hunt! ] 】

The audience coaxed, but Bi Fang shook his head and waved his hand to let the drone get closer.

Under the light and shadow, Bi Fang rubbed the bark that had already formed a scar, and looked down at the nearby soil: "It was left a long time ago, at least there is a moon, and there are no footprints on the ground, it should be left by a black bear passing by." ”

"Normally, the paw prints left by the tree can cut through the bark, revealing the white trunk, and now the trunk is blackened, oxidized for a long, long time, and it is impossible to find the black bear with this one."

"Unless it's in the vicinity, but that's obviously not true, because there are very few signs of other large animals in the vicinity other than this scratch."

It turned out to be a fake!

The audience was disappointed.

I thought that Boss Fang would be the first hunter to find the prey information in the morning.

However, the sudden appearance of the black bear's paw prints also reminded everyone that there are really black bears in this forest, and there are very many of them.

Bi Fang shook his head and put away his thoughts.

"Continuing with the topic just now, someone asked why bears like to eat honey, in fact, honey is not the main thing in all the food of bears, but honey is very important to bears."

Bi Fang chatted with the audience while walking, which is his usual style.

This is a test of concentration, you need to observe the surrounding environment, but also check the barrage in time, and respond, in other words, ordinary people don't have this ability, you may be tripped and fell while walking.

Bi Fang felt that with this, he had to show himself a dual-purpose skill.

"The food that bears eat is very mixed, and some foods are not easy to digest, and honey can promote digestion and absorption, improve the bears' own immunity, and allow their body energy to be replenished quickly."

"Secondly, when bears enter hibernation, they must rely on the conversion of body fat into energy to maintain their physical needs."

"Of all the nutrients, sugar is the easiest to convert into fat, and for these reasons, bears naturally like to eat honey very much."

"In addition to ant nests and honey, there are many places that are easy to observe, such as some shrubs with berries, which have been trampled and rotten, probably the lean black bear."

Bi Fang carefully explained all kinds of possible clues, and casually picked a small red fruit from the side of the branch mountain and stuffed it into his mouth.

"Well, it tastes good, sweet and sour."

[, what did Boss Fang stuff into his mouth? 】

[What kind of thing is this, just eat it, and you're not afraid of poisoning? 】

"Don't be nervous, it's just a hook, raspberry, it can also be aphrodisiac."

Bi Fangyao remembers that when he followed the old professors into the forest to investigate, the most eaten wild fruit was the sling.

Picking off the slings from the nearby bushes one by one, Bi Fang said: "In June, July, or even August, if you want to eat something good in the wild, then you can try to find a sling, because not only can you eat every species of Rubus genus, but most species are delicious." ”

"Most of the fruits that have not been artificially cultivated will not be delicious, sour and astringent, and some may even have slight toxicity, so it is really rare for the hook to evolve itself into a good taste." Frog

"The characteristics of Rubus are very memorable: shrub or woody vine, with skin spines on the veins on the back of the stems and leaves, and the fruit is a berry-like aggregate fruit that develops from multiple isolated carpels, which simply looks like a pomegranate fruit aggregated and is very tender."

"I won't say what the flowers look like, but seeing a hooked flower in the wild means that you came two months early."

Bi Fang plucked the small fruits from the bushes one by one, some of them were stuffed directly into his mouth, and some of them were put into small bags.

The ripe rubus fruits are juicy and delicious, and the most disadvantage is that some species are too sour, but there are very few, and this is obviously not the case in front of you.

It's also simple to eat, just take it down and stuff it in your mouth, but the flesh of wild species is too tender, it is impossible to store and transport, and it is easy to crush when stacked together, so it is rare to see any deep processing, even if there are people, they are basically picked.

"However, it is easy to identify Rubus and start eating, but it is very difficult to determine what kind of food is in your mouth, and the same is true for experienced plant taxonomists, and I don't even know what I just ate."

The classification of Rubus is a worldwide problem.

According to different classification systems, there are 250~700 species in this genus in the world - just look at the numbers to see how much taxonomists diverge on this genus.

Just like eating squid, some plants don't need to remember what they can eat when they survive in the wild, just remember what they can't eat in the genus.

"Among the squid, only the flame squid is poisonous, and all types of slings can be eaten, which is a simple way to remember."

Once, after eating wild hooks, Bi Fang habitually wanted to do the work of a genus, but he encountered obstacles.

One of his respected teachers gave advice: "Why don't you completely abandon the existing species divisions, first build a phylogenetic tree by molecular means, and then re-divide the species." ”

But at that time, Bi Fang estimated the difficulty of sampling, counted the shy funds in his pocket, and silently gave up.

I didn't expect that until now, I still can't make a suitable species, but my pockets are bulging, but I don't have much interest in classifying plants.

"Now the seed I have in my hands is single-leafed, with very few skin spines; The fruit is also solitary, with a sweet and sour taste that is difficult to describe. I feel a bit like a certain pesticide smell, but it is very light and does not affect the consumption, maybe it can be called a 'pesticide hook'. ”

[Hahahaha, this is too casual, right? 】

[Pesticide hook, I never thought I could get this name in my life]

[What is the name of the species that Lao Fang discovered last time? ] 】

[Bi's crocodile. 】

[Ah, yes, yes, that's it, it's waterlogged]

"Where is the crocodile waterlogged?" Bi Fang was puzzled, and said seriously, "A lot of creatures are called that, Bi's yeast, Bi's ovarian ant, it's all like this, the ovarian ant doesn't have a queen ant, it's a kind of marching ant, it's cool, okay." ”

[Ah, yes, yes, yes]

[When can I see Bi's crocodile in the zoo]

[Yes, does the old party know the news? Isn't that what you discovered? 】

"How do I know?"

Bi Fang shook his head, he didn't know the specific news, but it didn't seem to have any intention of developing it at all, but it protected it.

Even Bi Fang was told not to tell others the exact location.

But it doesn't matter, it's okay with me anyway.

The only news I know is that the head I brought back at the beginning was very tenacious, and after the new arrival, it was kept in the laboratory, which was very large, and someone fed it every day.

It is said that there is a meaning of taking a female crocodile to breed, and further observe the behavior and habits of this creature.
