The meaning of LIFESPAN is the average length of life of a kind of organism or of a material object especially in a particular environment or under specified circumstances.
Pine trees are one of the most popular types of trees in the world. They are known for their beautiful evergreen needles and cone-shaped fruits. Pine trees are found in almost every continent, and there are over 100 different species of pine tree. Pine trees can grow to be very tall, ...
Life span, the period of time between the birth and death of an organism. The maximum life span is a theoretical number whose exact value cannot be determined from existing knowledge about an organism; it is often given as a rough estimate based on the l
The meaning of LIFETIME is the duration of the existence of a living being (such as a person or an animal) or a thing (such as a star or a subatomic particle). How to use lifetime in a sentence.
In this long-term study we showed how sprouting can extend the persistence of seedlings. Sorbus aucuparia (rowan), a tree species with multi-stemmed seedlings growing in subalpine spruce forest, was chosen for this study. The main aim of the study was to examine the persistence of seedlings...

Existing data for animal longevity7–9 typically include values for the maximum observed lifespan of a species. These datasets include a mix of in situ and ex situ data, with many estimates from unknown (ex situ or wild) sources. Maximum lifespans are usually single observations, and therefore...
Discerning the relationship between sociality and longevity would permit a deeper understanding of how animal life history evolved. Here, we perform a phylogenetic comparative analysis of ~1000 mammalian species on three states of social organization (solitary, pair-living, and group-living) and longevi...
Comparative genomics has revealed extensive horizontal gene transfer among prokaryotes, a development that is often considered to undermine the 'tree of life' concept. However, the possibility remains that a statistical central trend still exists in the phylogenetic 'forest of life'. Results A comprehe...
