While human activities are causing a loss of much of the world's biodiversity, amphibians appear to be suffering much greater effects than other species of organisms.
間期、そして間期の各段階に費やす期間はさまざまであり、細胞種と生物種の双方に依存する。
The duration of time spent in interphase and in each stage of interphase is variable and depends on both the type of cell and the species of organism it belongs to.
We realize that even a limited nuclear war can provoke sudden extreme climate change on a global scale, crippling agricultural production and threatening the survival of all higher forms of life.
At the same time, this fact suggests that the recombination of 16S rRNA genes among species is comparatively flexible, and this is expected to be used as an important finding in examining the fitness of 16S rRNA gene for use as a molecular clock.
In the time it takes you to read this, acres of rainforest will vanish, a species will go extinct, women will be raped, men shot, and far too many children will die of easily preventable causes.
Ref. 2Many endemic and biogeologically important species reside on Uotsuri Island, but there is concern that if this situation is allowed to continue, the severe impact on the ecology of the island could lead to the extinction of many valuable species.
The Maui's dolphin population now stands at between 42 and 47 individuals, down from 59 in 2010/2011, according to a paper by Barbara Maas, Head of International Species Conservation at the German conservation group NABU International Foundation for Nature.
This ability has prompted investigation of their genomes, with the first genome sequence of a tardigrade(Hypsibius dujardini) suggesting that a significant amount of acquisition of genes from other species through horizontal gene transfer(transmission of DNA between genomes of different species) took place in tardigrade evolution.
Homologous,” in all its grammatical forms and spelling variations, refers to the relationship between two proteins that possess a“common evolutionary origin,” including proteins from superfamilies in the same species of organism, as well as homologous proteins from different species of organism.
This method is applicable either in vivo or ex vivo/in vitro, and, in cases of in vivo application, the species of organism may be either human or non-human(e.g., mammal such as mouse).
For example, when the designated value is 0.5, the cluster is determined as belonging to the"Plants" group if the sequences of four or more organism species out of seven species in this organism group exist in the cluster.
Habitat loss is a major cause of species extinction, and is principally associated with human disturbance(for example, through urban expansion or conversion of natural habitat to agriculture), but its impact on different species may vary according to the amount of habitat lost and where each species is found within it.
The ecological information for birds and mammal risk assessment consisted of data that is used for the determination of focal species, estimation of the proportion of an animal's daily diet obtained in a treated habitat(PT) and assessment of the composition of the diet obtained from a treated area(PD).
And with this famous entry in his notebook, he begins in the top left-hand corner with,"I think," and then sketches out the first tree of life, which is his perception of how all the species, all living things on Earth are connected through evolutionary history-- the origin of species through natural selection and divergence from an ancestral population.
Understanding the environment surrounding the factory, planning with consideration for the region's types of animals and ecosystem, along with increasing greenery through preservation of existing trees such as Shirakashi and native species such as Yoshi and Suge, changes of water levels were recorded at ponds with purposes such as multi-layer ecosystem.
