If there is more than 30 years old in your home faineant still do not go working gnaw old a group of things with common features, do not worry please too much.
Because be in recently, a new about Atlantic fossil and existent double carapace kind the big data of animal and gastropod considers to make clear, lazy it is individual likely, species even the community that a lot of species form will multiply a strength strategy. This research positive result is the closest just just by can Sa this the group of a research of the university is published in " England is royal institutional the journal of an association - B " on.
For this achievement, investigation content covered researcher to include to arrive from Pliocene metaphase now time of about 5 million years, they are led in the metabolization that analysed 299 kinds of species -- namely the energy that daily life place requires organism -- later, the possibility that discovers metabolization leads taller species to eradicate is larger, and this both dependency is very remarkable.
"Then we put forward such hypothesis again, ' what is there to contact? ' " can Sa this the postdoctoral researcher of institute of undergraduate content diversity and natural history museum, also be the say of Luke Strotz of the first author of this paper, "Through our investigation we discover, there is vast difference between the mollusc sort that already eradicated 5 million years in the past and the mollusc sort that still survive to go up at this world up to now. The metabolization of those mollusc that had eradicated is led often prep above survives the metabolization rate of those animals that come down. That is to say, the live thing that keeps life place to need those biology with inferior energy to want taller than having metabolization to lead it seems that survives more easily come down. The live thing that keeps life place to need those biology with inferior energy to want taller than having metabolization to lead it seems that survives more easily come down..
The author of this paper still has 3 collective writers besides Strotz, it is can Sa respectively this the collection of the biology diversity institute of the university manager Julien Kimmig, can Sa this university ecology and Bruce Lieberman of developmental biology professor and the Erin Saupe that come from Oxford.
Lieberman says, "Perhaps look from long-term point of view, the optimal strategy of animal evolution is the life rhythm with comfortable slow gentle - make metabolic rate lower so, the species that you belong to survives more likely come down; We all the time since say ' survival of the fittest ' , nevertheless perhaps to whole life history, better summary ought to be ' lazy person live ' , perhaps be at least ' slow person live ' . Perhaps be at least ' slow person live ' ..
Researcher expresses, in to forecasting what species to be in coming global climate change be in more likely short-term inside disappear, their this research work has important sense to its.
"In some sense, what we are studying is the potential influencing factor that a certain species eradicates probability, " Stroltz says. "From the point of whole species level, only metabolization rate is not the most important, bringing about extinct element finally have a lot of elements to act well jointly. But these research can explain as a result, the metabolization rate of organism is with eradicate one of elements related probability. The metabolization rate of a species is higher, this species is eradicated more likely. As be in the numerous tool of kit we discovered a new tool is same, this research will deepen the understanding of the mechanism that we eradicate to species, help us calculate the possibility that some species eradicates better. Help us calculate the possibility that some species eradicates better..
Arcinella Cornuta (on the biology in the graph) it is the place in article say that new concerned Atlantic fossil and existent double carapace kind a species that studies in the big data research of animal and gastropod. This considers to make clear, lazy likelihood is individual, the community that numerous even species forms species lives a strategy that multiply expands.
Study the group returns discovery, higher metabolization rate is a when judgement eradicates probability more accurate index, be restricted to be on the habitat with lesser some when the life limits of the species that is judged especially, this is both the associated sex between is stronger; And distributing when some species when relatively vast marine geography area, associated sex is fewer.
"We discover, relatively capacious species is in distributinging limits to eradicate and metabolize the dependency respect between rate, what with those distributinging limits lesser species behaves is different, " Strotz says, "So, the distributinging scope magnitude of this species also is one of influencing factor that its eradicate probability, the possibility that the species with distributinging narrower range eradicates it seems that is a few larger. And if become some biology distributinging range is narrow and metabolization rate is very high, the possibility that then this species eradicates will be very tall. The possibility that then this species eradicates will be very tall..
This group returns discovery, one by different and individual or always accumulate metabolization rate of the community that species forms to always can hold the range in stability inside, although always have inside this community,differ individual or species appears inside community or die out.
"If you go analysing whole community and make all species in these community, you can discover the average metabolization rate of this community whole to often can keep changeless, " Strotz says, "The total energy level of whole community carries a static state it seems that since settle on. The development of new species, or the numerary that a certain already have species expands the growth that the energy of brings addition spends, just touched what the eradicate and brings energy of those other species uses up to decrease it seems that. To researcher, this is a surprizing discovery, because connect ordinary people to be able to guess, as the elapse of time the metabolic rate of a community affirms meeting as the elapse of time change. But fact rather, although a lot of species were eradicated, but these double carapace kind with abdominal foot or leg kind the animal is whole of community average energy is absorbed still maintain hundreds all ages changeless.
Strotz still says, he uses mollusc to study metabolism and the research that eradicate the dependency of probability, because this one community is having enougher concerned living things and the data that eradicate species,be.
"We need very big database, the bag wants to contain many species and incident inside, " he says. "These double carapace kind still survive up to now with a lot of species in gastropod, so we can are opposite now from us strange vivid double case kind the data that with abdominal foot or leg physiological understanding gets we need. Because this area has better large data set,we choose the area that ocean regards Xidaxi as to be studied is, this area was recorded inside of more fossil and life mollusc distributing. And I still used a lot of fossil material that come from American each district to consider. And I still used a lot of fossil material that come from American each district to consider..
Study the group shows, after this one investigation next, will be affirmatory to other species, metabolization rate and eradicate the dependency between probability.
"We think we this research popularizes other community as a result also likewise will applicable, perhaps be at least in the other community of marine domain applicable, " Strotz says, "Later next, will be the other branch community that the conclusion that whether can test and verify study this expands with what study now community is having same ancestry, look to these community our research conclusion is applicable. The issue that at present we still are studying is, whether this one conclusion is opposite only is mollusc applicable? We choose mollusc have a few reason, for instance the size of these biologic data set, and the time that they cover on the history is longer, and they still survive to go up in the world up to now. But we still resemble studying other live thing, does this one conclusion look to you can apply to vertebrate in light of? Be perhaps it can apply to land even? Be perhaps it can apply to land even??
